Outpatient Intravenous Insulin Treatment (Therapy)

1. The Centers for Medicare and Medicaid Services (CMS) proposes the following. 

   The evidence is adequate to conclude that outpatient intravenous insulin therapy does not improve health outcomes in Medicare beneficiaries.  Therefore, CMS has determined that outpatient intravenous insulin therapy is not reasonable and necessary for any indication under Section 1862(a)(1)(A) of the Social Security Act.  Services comprising an Outpatient Intravenous Insulin Therapy regimen are nationally noncovered under Medicare when furnished pursuant to an outpatient intravenous insulin therapy regimen.

2. Outpatient Intravenous Insulin Therapy (OIVIT) consists of an outpatient regimen of pulsatile or continuous intravenous infusion of insulin via any means, guided by the results of:
   • measurement of respiratory quotient; and/or
   • measurement of urine urea nitrogen (UUN); and/or
   • measurement of arterial, venous or capillary glucose; and/or
   • measurement of potassium concentration;

   performed in scheduled recurring intermittent episodes.

   This regimen is also sometimes termed Cellular Activation Therapy (CAT), Chronic Intermittent Intravenous Insulin Therapy (CIIT), Hepatic Activation Therapy (HAT), Intercellular Activation Therapy (iCAT), Metabolic Activation Therapy (MAT), Pulsatile Intravenous Insulin Treatment (PIVIT), Pulse Insulin Therapy (PIT) and Pulsatile Therapy (PT).

We request public comments on this proposed determination pursuant to section 1862(l) of the Social Security Act.  After considering the public comments and any additional evidence, we will make a final determination and issue a final decision memorandum.

I. Proposed Decision

1. The Centers for Medicare and Medicaid Services (CMS) proposes the following.

   The evidence is adequate to conclude that outpatient intravenous insulin therapy does not improve health outcomes in Medicare beneficiaries. Therefore, CMS has determined that outpatient intravenous insulin therapy is not reasonable and necessary for any indication under Section 1862(a)(1)(A) of the Social Security Act. Services comprising an Outpatient Intravenous Insulin Therapy regimen are nationally noncovered under Medicare when furnished pursuant to an outpatient intravenous insulin therapy regimen.

2. Outpatient Intravenous Insulin Therapy (OIVIT) consists of an outpatient regimen of pulsatile or continuous intravenous infusion of insulin via any means, guided by the results of:
   • measurement of respiratory quotient; and/or
   • measurement of urine urea nitrogen (UUN); and/or
   • measurement of arterial, venous or capillary glucose; and/or
   • measurement of potassium concentration;

   performed in scheduled recurring intermittent episodes.

   This regimen is also sometimes termed Cellular Activation Therapy (CAT), Chronic Intermittent Intravenous Insulin Therapy (CIIT), Hepatic Activation Therapy (HAT), Intercellular Activation Therapy (iCAT), Metabolic Activation Therapy (MAT), Pulsatile Intravenous Insulin Treatment (PIVIT), Pulse Insulin Therapy (PIT) and Pulsatile Therapy (PT).

We request public comments on this proposed determination pursuant to section 1862(l) of the Social Security Act. After considering the public comments and any additional evidence, we will make a final determination and issue a final decision memorandum.

II. Background

Terminology
The term outpatient intravenous (IV) insulin therapy (OIVIT) refers to an outpatient regimen that integrates pulsatile or continuous intravenous infusion of insulin via any means, guided by the results of:

performed in scheduled recurring intermittent episodes.

The term diabetes refers to diabetes mellitus (DM) unless we describe a more specific use. We specify Type 1 or Type 2 DM when the discussion refers to one type rather than to both. The terms hypo- and hyperkalemia refer respectively to abnormally low or high levels of potassium (from the Latin kallium) in the blood. The terms hypo- and hyperglycemia refer respectively to abnormally low or high levels of glucose (from the Greek glykys) in the blood. The term endogenous is an adjective referring to internal bodily processes or the products of internal bodily processes. Glycogen is a large molecule consisting largely of multiple glucose molecules linked together, and serves as a means to store energy. The term hepatic is an adjective that refers to the liver.

Proteins are comprised of amino acids, many of which are derived from dietary sources. A peptide may be thought of as a small fragment consisting generally of fewer amino acids than a protein. Insulin is an example of a peptide hormone.

A cell may store substances in tiny packets called vesicles, or substances may be dispersed more generally in the intracellular liquid environment (cytosol). Cells release substances through a variety of mechanisms. Small molecules may traverse the cell membrane via specific gates or channels. Cells may also release substances through a process called exocytosis, by which a vesicle will merge with the cell’s membrane and discharge its contents directly into the surrounding environment.

Human cells display electrochemical activity to various degrees, depending on their biologic function. The electrical properties of cells are determined by the relative concentrations of electrically charged atoms (ions) inside and outside of the cell. Sodium, potassium, calcium and chloride are examples of ions that play a significant role. When various stimuli cause these ions to move into or out of the cell in a coordinated manner the cell becomes momentarily "depolarized." Energy is required to maintain this electrical balance. Adenosine triphosphate (ATP) is a nucleotide molecule which stores cellular energy in its bonds to its three phosphates; adenosine monophosphate (AMP) and adenosine diphosphate (ADP) store lower amounts of cellular energy with their one and two phosphate units respectively. A kinase is a type of enzyme. Additional terms are defined below as needed.

Scope of this decision
We recognize that various individual components of OIVIT may have medical uses in conventional treatment regimens for diabetes and other conditions. In this decision, we are not making (a) coverage determination(s) regarding those other various uses. Coverage for such other uses may be determined by other local or national Medicare determinations and will not be considered here.

We remind the reader that Medicare differentiates the clinical laboratory diagnostic glucose testing performed by medical professionals from the home self-monitoring of glucose that is customarily performed by patients. The test equipment and supplies for home self-monitoring are coverable under the durable medical equipment (DME) benefit and are not payable as diagnostic tests for Medicare purposes. As such, they are not included in the scope of this review.

Commercially available insulin preparations
Various preparations of insulin have FDA approved labeling to improve glycemic control in adults and children with diabetes mellitus. The commercially available insulin products are marketed by many manufacturers. The original animal-derived insulins (beef, pork) have been largely supplanted by recombinant (genetic technology) human insulin or recombinant insulin analogues, ^{(Brogden 1987, Chance 1993, Heller 2007, Hoome 1982, Ladisch 1992)} The pharmacokinetic and pharmacodynamic activity profiles of the various insulin products depend on changes in the primary molecular structure of the insulin (native insulin versus insulin analogue), the addition of modifying components such as zinc and protamine, and the route of administration (subcutaneous versus intravenous). ^{(Bruni 1973, Hagedorn 1936, Meneghini 2008, Scott 1935)} There are unlabelled uses of IV insulin unrelated to diabetes mellitus, such as the rapid correction of emergent hyperkalemia in the setting of cardiac toxicity. ^{(Allon 1990, Birmbaum in Olson 2004, Hollander-Rodriguez 2006, Kocoglu 2002)}

Endogenous insulin
The pancreas is a gland that has both exocrine (digestive enzymes) and endocrine (digestive hormones) functions. The specialized areas producing hormones are islets (of Langerhans) and are scattered throughout the pancreas. The various islets contain "alpha", "beta", "delta", and "epsilon" cells, which secrete the hormones "glucagon", "insulin", "somatostatin", and "ghrelin" respectively. ^{(Andralojc 2008, Dezaki 2006, Docherty 2001, Gromada 2007)} Insulin is produced as proinsulin, which is cleaved in the beta cells to produce insulin and C-peptide. C-peptide has no definitively established metabolic effect, but is measurable as a marker for insulin production by the pancreas and to differentiate endogenously produced insulin from administered insulin preparations in blood samples.^{(Brandenburg 2008, Hills 2008, Norquist 2008)}

Insulin and its counter-regulatory hormone, glucagon, are released into the portal vein, through which they enter the liver. The portal venous system is anatomically unique in that venous blood from the small intestine is directed to the liver rather than returning directly through the systemic (general) venous system to the heart. Thus insulin, glucagon, digested nutrients and drugs may be found in higher concentrations in the portal vein than in the systemic venous circulation, and may act upon or be acted upon by the liver before entering the systemic venous circulation. In contrast, digestive enzymes are released into the pancreatic duct and subsequently enter the common bile duct, from which they are delivered into the duodenal part of the small intestine through a natural opening called the ampulla of Vater.

As noted above, insulin has uses beyond diabetes. However, because it is illustrative of insulin’s biochemical actions and clinical effects, we have included a detailed discussion of diabetes and insulin below. We recognize that this discussion may be complex for the lay reader, but the underlying topic is itself complex, and we believe that oversimplification will lead to misinterpretation and misunderstanding.

Diabetes
Diabetes encompasses a spectrum of metabolic disorders. Classical Type 1 DM (previously termed Juvenile Diabetes) is an autoimmune disorder in which there is destruction of the pancreatic islet cells that produce insulin, and sometimes also the islet cells that produce counter-regulatory hormones that mitigate hypoglycemia. Because they lack endogenous insulin, Type 1 diabetic patients require insulin replacement in multiple doses throughout the day to prevent ketoacidosis. This contrasts with Type 2 DM (previously termed Adult-Onset Diabetes), in which insulin is still produced, but is secreted in insufficient quantities to meet insulin requirements because of impaired insulin action (resistance). These patients do not require daily insulin to avoid ketoacidosis, but may benefit from insulin supplementation to correct nocturnal hyperglycemia or post-prandial (after eating) hyperglycemia. Patients with mixed disorders may require therapeutic intervention with modalities and regimens from both Type 1 and Type 2 diabetes.

Physiology of insulin secretion
In the following section, we describe the physiology of insulin secretion. We believe this is important because some proponents of OIVIT cite the importance of mimicking the endogenous release of insulin in support of their claims.

Glucose utilization by the body is mediated by both insulin and non-insulin mediated mechanisms (Figure 1). ^{(Baron 1987, 1988, Saltie/ Pessin 2007)} The beta cells in the pancreatic islets secrete insulin into the hepatic portal vein (splenic-mesenteric confluence), which drains the mesenteric (largely digestive) organs and supplies the liver. ^{(Bergman 2000, Moore 2003)} Insulin levels in the portal vein are substantially higher than in the hepatic vein, which drains the liver, and in other peripheral veins. Exposure to high insulin levels results in suppression of hepatic gluconeogenesis (glucose formation) and an increase in hepatic glycogenesis (glycogen formation). Insulin exposure in the peripheral circulation causes glycogenesis in muscle tissue and triglyceride disposition in adipose (fatty) tissue. ^{(De Meyts 2000)}

Figure 1: Pictorial of Glucose Utilization and the Role of Insulin

Insulin release is mediated by a variety of activating or inhibitory triggers including nutrients, neurotransmitters, chemical signals and drugs. ^{(Martens 2009, Torres 2009)} Glucose enters pancreatic beta cells via glucose transporters (GLUT 2) and is metabolized to ATP. ^{(Ashcroft 1999, 2006, Jensen 2008, Thorens 2001)} The relative excess of ATP compared to ADP results in the closure of potassium ATP channels and thus produces cellular membrane depolarization. This depolarization opens voltage-dependent channels and permits extracellular calcium influx. Higher levels of calcium in the cytosol results in insulin exocytosis. ^{(Hou 2009, Weiderkehr 2008)}

Insulin release can occur both 1) in response to glucose exposure or mixed meals; and 2) in background oscillation patterns present even during the fasted state. ^{(Goodner 1982, Lefebvre 1987, Porksen 1995, 1997, Weigle 1987)} Like other peptide hormones it is secreted in pulses.^{(Carmel 1976, Dierschke 1970, Goodner 1977, Lang 1979, 1982, Laursen 199, Stagner 1980, Shapiro 1988, Tannenbaum 1976)} Background insulin secretion occurs in high frequency pulses (8-15 minute intervals) and ultradian (recurrent cycles within a 24 hour period) pulses. ^{(Goodner 1977, Lang 1979, Polonsky 1988x2 NEJM), Sturis 1992, Song 2000)}

Classically, insulin release was thought to occur in two segments: first-phase, which is a short secretory burst occurring within minutes of a stimulus, and second-phase, which is longer in duration and whose magnitude reflects the extent of stimulus. ^{(Caumo 2004, Cherrington 2002, del Prato 2002. Henquin 2002)} First-phase insulin release is diminished in patients with Type 2 diabetes and may be impaired in subjects at risk for the development of Type 1 diabetes. ^{(Cutfield 2004, Fujita 1975, Grendal 2007, Porte 1991, Ratzmann 1981, Smith 1988, Vialettes 1988)} As the technologic capability to detect hormone pulsations has improved, it has become apparent that the classic two-phase release reflects an extreme response to a large and sudden glucose load. Under more physiologic stimulus conditions than an intravenous glucose bolus, the occillatory pattern of insulin release changes, but is not as discrete. ^{(Caumo 2004, Lefebvre 1987, Matthews 1991, Polonsky 1995, 1998, Porksen 2002)}

Insulin pulsatility can vary by amplitude, inter-pulse interval, and regularity of periodicity. Abnormalities in the background insulin oscillations are present in patients with Type 2 diabetes, in high risk relatives of patients with Type 2 diabetes, and in obese patients with insulin resistance. ^{(Hollingdal 2000, Hunter 1996, Juhl 2001, Lang 1981, O’Rahilly 1988, Radetti 1998, Zarkovic 1999)} These abnormal pulsatile patterns can be normalized by weight loss. ^{(Radetti 1998, Zarkovic 2000)} Conversely, a pattern of the normal number of pulses, but lower insulin content per pulse, is present in persons engaged in endurance training. ^{(Engdahl 1995)} Curiously, although there appears to be a correlation between the insulin pulsatility frequency and peripheral insulin sensitivity, a similar relationship was not present for hepatic insulin sensitivity. ^{(Hunter 1996)}

Some investigators have focused on the response of the liver to insulin in the portal venous system. Indeed, it is known that hepatic enzymes involved in glucose metabolism, e.g., hepatic glucokinase (hexokinase IV), phosphofructokinase, and pyruvate kinase require higher insulin levels (200-500 μU/ml) than can be achieved by absorption of subcutaneous insulin into the peripheral venous system. ^{(Aoki 1992, Basu 2000, Clark [Saltiel, Pessin] 2007, Vester 1963)} Furthermore, some, but not all, investigators observed increased hepatic extraction of insulin during endogenous insulin pulsations. ^{(Grubert 2005, Meier 2005)} It is thought that this entrainment (synchronization) of hepatic insulin receptor turnover optimally suppresses endogenous hepatic glucose output and determines the amount of insulin to be delivered to the peripheral circulation. These findings prompted some researchers to consider insulin treatments which more closely replicate the normal physiologic state and increase the amount of portal vein and hepatic exposure to insulin. Although peritoneal or portal vein delivery could achieve this goal, these routes of administration are very invasive and impractical. Intravenous administration can approximate these levels of hepatic exposure to insulin only if systemic venous insulin levels (and the risks of hypoglycemia) are also high. Nonetheless, some investigators have proposed these alternative routes of insulin administration.

Diabetes and standard insulin therapy
In the following section, we describe the typical route of administration (subcutaneous injection), along with some additional routes of administration that are under development, because all of these are generally self-administered, unlike intravenous insulin. We then describe the typical inpatient settings in which IV insulin infusion might be transiently employed and the types of monitoring that are required for safe administration.

Because insulin and insulin analogues are proteins, they are degraded and/or denatured in the digestive tract. For this reason, the majority of insulin products are given parenterally, i.e. via routes that do not involve the gastrointestinal (GI) tract. The standard outpatient route of administration is a) subcutaneous injection via syringe or pen-cartridge device; or b) subcutaneous infusion from an external pump (usually programmable with bolus and basal rates). ^{(Bohannon 1999, Pickup 1997, Saudek 1997)} In patients on peritoneal dialysis, insulin may be added to the dialysate (dialysis fluid). ^{(Chan 1993, Tzamaloukas 1991)} Although less invasive methods of insulin administration (inhaled, buccal, or oral) were or are under investigation, patients can safely self-administer insulin via the more invasive standard parenteral routes. ^{( C&E News, DOC, Drugs.com; FDA Dear Doctor Letter, Heller 20007, Khafagy 2007; Royle 2004 with Cochrane update 2008, Yadav 2009)}

There are circumstances under which insulin therapy is administered IV by a third party. Intravenous insulin is commonly employed to treat patients with diabetic ketotic acidosis (also known as ketoacidosis, a life threatening condition), hyperosmolar coma, limited consciousness, and rapidly changing nutritional needs and intake. ^{(Braithwaite 2003, Furnary 2003, Harrower 1979, Kitabchi 2003, Knapke 1989, Lazar 2000, Malmberg 1997, Park 1992, Pezzarossa 1988, Piters 1977, Pomposelli 1998, Scott 1999, Van den Berghe 2003,Woolfson 1981, Zerr 1997)} The IV route of insulin administration is employed under these types of circumstances because the onset of insulin action is rapid and the drug half-life short; permitting rapid therapeutic intervention in response to rapidly changing clinical conditions. ^{(Turnheim 1988)} When such IV insulin therapy is administered, it is performed in an inpatient hospital setting such as in the intensive care unit, the surgical suite, and the step-down unit where the capacity to monitor patients with professional clinical laboratory testing (glucose and electrolytes including potassium levels) and skilled nursing staff are present. ^{(Braithwaite 2004, Grissinger 2003, Hellman 2004, Joint Commission 2000, Paice 1986)} The duration of IV insulin therapy is short; patients are switched to sustainable, less invasive, less risky treatment modalities when their condition stabilizes. ^{(Laveria 2008)}

When administered intravenously, the insulin product typically is diluted to a fixed dose, e.g., 1 unit insulin/1 cc of normal saline, piggy-backed onto the maintenance IV line flowing through an adjustable rate pump. ^{(Joint Commission 2000)} A concomitant IV potassium solution is also piggy-backed into the infusion system. Intravenous insulin is administered as part of a diluted solution along with adjunctive potassium in the setting of monitoring to enhance patient safety because the therapeutic index (lethal dose divided by the therapeutic dose) is very narrow when given by this route. ^{(Braithwaite 2004, Grissinger 2003, Hellman 2004)} In addition to the potential lethality of hypoglycemia, patients are at risk for hypokalemia because of the intracellular flux (flow from the blood into the cells) of potassium with insulin administration. ^{(Bergman 1982, Rave 1999, Simmons 1994, Tattersall 1999)} Hypokalemia itself can be lethal because it precipitates cardiac rhythm disturbances. ^{(Alfonzo 2006, Cohn 2000)}

Diabetes and metabolic measurements
In the following section, we delineate the typical role of respiratory gas measurements, and the respiratory quotient (RQ) measurement in particular, in medical care and physiologic assessment. We do this because serial outpatient respiratory quotient values have been advocated by some as a means of assessing the metabolic response to insulin dosing in OIVIT and as a tool for determining subsequent insulin dosing in OIVIT.

Metabolism can be determined by measurements of inspired O₂ (oxygen) and expired O₂ and CO₂ (carbon dioxide). ^{(Bartlett 1952, Fuji 2003)} The respiratory exchange ratio (RER) (CO₂ elimination/O₂ absorbed across alveolar capillary membranes) is the same as the RQ (CO₂ production/O₂ utilization) under steady state (equilibrium) conditions. The respiratory quotient of completely oxidized substrates is represented by: the number of carbon atoms in the fuel molecule divided by the number of carbon atoms plus the number of hydrogen atoms divided by four and minus the number of oxygen atoms divided by 2 (carbon #/ carbon + [hydrogen #/4] –[oxygen #/2]). Complete metabolism of pure carbohydrate substrate yields a RQ of 1.0 whereas complete metabolism of fat yields a respiratory quotient of approximately 0.7. The RQ associated with proteins is mid-range and is complicated by a variety of metabolic pathways. In other words, the value of the RQ reflects the extent to which a food substrate is oxidized and the composition of that food substrate. The advocates of OIVIT interpret the RQ as a measurement of carbohydrate metabolic efficacy.

The accuracy and/or utility of this RQ ratio depends on a number of factors including a) the absence of substrate other than carbohydrate, fat and protein, b) substrate disappearance only due to oxidation (and not the urinary losses of glucose or protein that can be present in diabetes), c) the rested state, and d) the fasted state. Furthermore, there are errors in the measured metabolic rate that are introduced when the urinary urea nitrogen (UUN) component is not included in the calculation. ^{(Mansell 1990)} Typically these measurements are obtained through indirect calorimetry (measurement of heat [energy] using respiratory gases) using metabolic carts (an instrument that measures respiratory gases). Some determinations such as resting energy expenditure (REE) may require the use of additional equations (Fleisch, Harrison-Benedict, or Reed) and patient data. The carts must be regularly calibrated. ^{(Diamond 2007, Hopkins 2003 Policy 159)} All devices may not provide comparable data. ^{(Webster 1999, Wells 1998)} Typically, RQ measurement is limited to the inpatient setting. Frequently, the measurements are used in the adjustment of nutrition and ventilation parameters. ^{(AARC 2004)} Such measurements would not be taken more often than once daily.

There are RQ related measures, Basal Metabolic Rate (BMR) and REE, which are more typically taken in the outpatient setting. ^{(Compher 2006, Henry 2005)} The former is the energy expenditure in the rested, fasted (10-12 hrs), thermally neutral state. The latter does not require the same degree of fasting. BMR (kcal/24 hrs) ~ REE (kcal/24 hrs) = 5.68 VO₂ (ml/min) + 1.59 VCO₂ - 2.17 UUN g/24 hrs = 5.46 VO₂ + 1.75 VCO₂. These are used in weight management and weight loss programs. Serial measurements are seldom required. Other measurements, such as VO₂ max, are obtained during exercise for cardiopulmonary or fitness testing. ^{(ATS/ACCP 2003, Diamond 2007, Guimaraes 2008)} Multiple determinations within a 24 hour period are seldom required.

Outpatient Intravenous Insulin Therapy (OIVIT) Development
In OIVIT, insulin is intravenously administered in the outpatient setting for a variety of indications. Most commonly, it is delivered in pulses, but it may be delivered as a more conventional drip solution. ^{(ADRI, MI, Strategic Partners-Bionica, VitalCare, Pulse Medix, Normedex, Diabetes.net.)} The insulin administration is adjunctive to the patient’s routine diabetic management regimen (oral agent or insulin-based) or other disease management regimen, typically performed on an intermittent basis (often weekly), and frequently performed chronically without duration limits. ^(ADRI) Glucose or other carbohydrate is available ad libitum (in accordance with patient desire).

Infusion sessions may be accompanied by multiple metabolic measurements, primarily RQ to assess oxygen utilization and carbon dioxide production from glucose metabolism. Insulin dosing may be determined via six serial (pre-, post-) measurements. These RQ measurements may or may not include a UUN component. Other monitoring includes glucose measurements, although the precision and accuracy of methodology and the frequency of assessment are not well delineated. It is not known whether serum potassium, serum triglycerides, and organ lipid/fat accumulation are monitored. ^{(See Insulin Delivery.) (Agius 2009)} Some business plans describe the use of closed or semi-closed loop systems for administration in the home setting. ^{(See Appendix 3 Strategic Partners-Bionica)} Blood will be intermittently aspirated by the infusion pump. Glucose levels will be detected by sensors and could be monitored remotely. Insulin will be delivered from commercial cartridges and not via standard diluting solutions.

Claimed benefits for this therapy include 1) improved glycemic control without increased hypoglycemia or with reduced hypoglycemia; 2) improved blood pressure control; 3) decreased progression of nephropathy; 4) reversed autonomic neuropathy (postural hypotension, abnormal diurnal blood pressure, hypoglycemic unawareness); 5) improved wound healing and reduced amputation risk; 6) reduced perception of disability; and 7) improved quality of life. ^{(Logan-Darroguh 1995) (See Appendices 1 ADRI, 7Aoki patent series)} More speculative claims involve use of the therapy in the peri-islet cell transplant period and use in non-diabetic patients. ^{(Mirbolooki 2009) (See Appendices 2 MI, 6 Aoki patent series, 7 Normedex)} Furthermore, it has been claimed that no adverse events have ever been reported for this treatment. ^{(See Appendices 3 Strategic Partners-Bionica, 7 Normedex)}

The physiology underlying this therapy was studied extensively in Europe, but this line of investigation was abandoned there in the early 1990s after a series of conflicting study results. (See Exploratory Studies in Humans.) Of note, respiratory quotients were not used for either dosing or efficacy assessment in the European studies. This is in contrast to the subsequent commercialization in the U.S. ^{(ADRI, MI, Strategic Partners-Bionica, VitalCare, Pulse Medix, Normedex, Diabetes.net, SEC Files)} The initial proponents of this therapeutic regimen were Dr. Thomas Aoki and colleagues. To further study the regimen and treat patients, the Aoki Diabetes Treatment Institute (ADRI) was founded in 1986. ^(ADRI) Dr. Aoki holds patents for metabolic activation therapy for a variety of diabetic and non-diabetic indications. ^{(Aoki Patent Series)} Respiratory quotient measurements are integral to his proprietary treatment regimen, which is available at ADRI and other authorized institutions. ^{(ADRI, ADRI Injunction, MI, Strategic Partners-Bionica, VitalCare, Pulse Medix, Nomedex, CA Cases )} A variety of other clinics provide similar therapy. ^{(ADRI, MI, Strategic Partners-Bionica, VitalCare, Pulse Medix, Nomedex, Diabetes.net)}

OIVIT could involve computer input of data and/or dosing algorithm.

Exploratory animal studies
There have been three important animal studies in which IV insulin therapy was employed. We include them as background as they illustrate the preliminary research in this field. One study was a short-term physiology study. Two studies employed IV insulin as a chronic treatment. In the latter two studies, the IV insulin therapy replaced standard therapy; it was not used as intermittent adjunctive therapy.

Grubert et al. studied 15 fasted non-diabetic mongrel dogs with the 3.5 hour glucose clamp. ^{(Grubert 2005)} Endogenous insulin was suppressed with somatostatin. Glucagon was kept constant. Sampling catheters were placed in the portal and hepatic veins as well as the aorta. Infusion catheters were placed in the splenic and jejunal veins (a physiologic location). The dogs underwent three infusion procedures: constant insulin infusion (1 µU/kg/min, pulsatile insulin (12 µU/kg/min over 1 minute q 12 minutes), and pulsatile insulin (3 µU/kg/min over 4 minutes every 12 minutes). The results indicated that hepatic glucose uptake did not differ by the infusion mode or by the amplitude and duration of the insulin pulse when the pulses were given at 12 minute intervals (physiologic for canines).

Weigle et al. studied five streptozoticin-induced diabetic baboons over three ~ 1-month long treatment periods (pulsatile insulinà continuous insulinà pulsatile insulin). ^{(Weigle 1991)} Insulin needs throughout the day were determined and then delivered either continuously or as pulses every 10 minutes. (N.B. This differs from the use of intravenous insulin as adjunctive therapy.) Endpoints included four-times daily glucose values, HbA1_c, fasting hepatic glucose production (via titrated glucose dilution) and beta-cell function (via response to glucose and arginine loads). Counter-regulatory hormones and other metabolic parameters were also measured. There were no differences by treatment group. Of note, glucagon secretion, which is postulated to contribute to the putative glycemic control associated with pulsatile insulin, was not entrained by insulin. ^{(Matthews 1983, Paolisso 1987, 1988)}

Koopmans et al. studied 25 streptozoticin-induced diabetic rats in parallel treatment groups (pulsatile insulin, continuous insulin, control) for ~ 18 days. ^{(Koopmans 1996)} Endpoints included fasting glucose levels, fasting insulin levels, diurnal glucose areas-under-the-curve, diurnal insulin areas-under-the-curve and urinary glucose levels. Counter-regulatory hormones, insulin binding, glucose uptake by adipocytes and glycerol production by adipocytes were also measured. Glycemic control was markedly improved as was the anti-lipolytic action of insulin (as measured by glycerol production) in the setting of pulsatile insulin.

Results from animal studies assessing pulsatile IV insulin have been contradictory. The reasons for the disparate animal results are not well understood. The baboons had a higher level of endogenous insulin reserve (comparable to some patients with Type 2 diabetes) whereas the dogs had endogenous insulin suppressed by somatostatin and the rats had a lower insulin level (comparable to Type 1 diabetes). It is possible that higher levels of endogenous insulin obscure small insulin pulses or that longer periods of infusion are required or that the biologic benefit conferred by pulsatility is relatively small in comparison to other environmental factors. ^{(Grubert 2005, Koopmans 1996, Schmitz 1986, 1994, Wiegle 1991)}

No animal studies have demonstrated that exogenous IV insulin therapy results in improved glycemic control via activation of hepatic enzymes, e.g., hepatic glucokinase (hexokinase IV), phosphofructokinase, and pyruvate kinase. Hexokinase IV has been studied via glucokinase activators and by genetic over-expression. ^{(Ajius 1995, 2009, Coughlan 2008, Gunn 1973, Hariharan 1997, Mateo 1989, Matschinsky 2006, Pal 2009, Payne 2007, Postic 2001, Soane 1996, Takeuchi 1996, Tilley 2009)} In a rodent model using titrated doses of the hexokinase IV gene in a viral vector, even gene activity that was six-times the normal did not result in euglycemia. ^{(Torres 2009)} Other studies have suggested that activation of this enzyme could result in hypertriglyeridema and pathologic lipid deposition. ^{(O’Doherty 1999, Pal 2009)}

III. History of Medicare Coverage

The outpatient intravenous insulin therapy regimen has several constituent components which are discussed below. We also make note other items and services related to other uses of insulin to make clear to the reader that they do not pertain to OIVIT.

A. National Coverage Determinations

There is currently no national coverage determination on the outpatient intravenous insulin therapy regimen as an integrated program.

There is currently no national coverage determination on the intravenous administration of insulin.

There is currently no national coverage determination on respiratory quotient testing.

There is currently no national coverage determination on metabolic cart testing.

There is currently no national coverage determination on urine urea nitrogen (UUN) testing.

There is currently no national coverage determination on serum potassium testing.

Medicare has a national coverage determination on Glucose Testing as a diagnostic laboratory test, at 190.20 of the NCD Manual. It includes the following among its indications and limitations:

We note for the reader’s convenience the Home Glucose Monitors NCD at 40.2 of the NCD Manual. We are not making a determination on home glucose testing with this decision. Diagnostic testing of glucose levels is distinguished from home glucose testing, which is covered as durable medical equipment (DME).

We note only for the reader’s convenience that Medicare has a national coverage determination on Closed-loop Blood Glucose Control Device (CBGCD) as an inpatient hospital service at 40.3 of the NCD Manual. However, OIVIT as described is not the same as CBGCD. It includes the following indications and limitations:

We also note only for the reader’s convenience that Medicare has a national coverage determination on Infusion Pumps at 280.14 of the NCD Manual. However, this addresses the subcutaneous administration of insulin, not the IV administration.

B. Benefit Categories
Because Medicare is a defined benefit program, an item or service must fall within a benefit category as a prerequisite to Medicare coverage: 1812 (Scope of Part A); 1832 (Scope of Part B); 1861(s) (Definition of Medical and Other Health Services); of the Social Security Act.

1. Insulin and Insulin Infusion
Drugs and biologicals and the administration of drugs and biologicals may be considered to be within the benefit category of the Social Security Act Section 1861(s)(1), physicians’ services; section 1861(s)(2)(A), services and supplies (including drugs and biologicals which are not usually self-administered by the patient) furnished as incident to a physician’s professional service; and Section 1861(s)(2)(B), hospital services (including drugs and biologicals which are not usually self-administered by the patient) incident to physicians’ services rendered to outpatients.

2. Metabolic Cart/Respiratory Quotient
The metabolic testing may be considered a benefit under the benefit category set forth in Title XVIII of the Social Security Act, Section 1861(s)(3) (diagnostic tests - other), a Part B benefit.

IV. Timeline of Recent Activities

March 25, 2009: The CMS opened an internally generated National Coverage Analysis (NCA) to evaluate the available evidence for outpatient intravenous insulin treatment, as well as the devices used to administer the therapy and the laboratory monitoring and medical-nursing surveillance required for implementation in the various outpatient settings, and the role for accompanying metabolic testing (including respiratory quotients). The initial 30-day comment period began.

April 24, 2009: The initial 30-day public comment period closed; 187 timely comments were received.

August 31, 20009: CMS met with Dr. Thomas Aoki, Mr. Bruce Parsons and Mr. Dick Costigan from the Aoki Institute.

V. Food and Drug Administration (FDA) Status

The treatment regimen under evaluation consists of multiple elements; some of which are intrinsic to the regimen and others which are optional: a biological pharmaceutical agent, an intravenous infusion device, glucose monitoring device, a metabolic cart for the determination of respiratory quotients, and a treatment regimen. The pump may have the capacity to be programmed for the delivery of insulin pulse patterns. The pump may have an integrated glucose monitoring device. The pump may be linked to a computer. A computer may integrate information about glucose levels, prior drug responsiveness, and respiratory quotients as well as other variables. The treatment regimen may be explicitly codified as a treatment algorithm or nomogram or may be more implicit. None of the proposed elements have specifically been approved by the FDA for outpatient intravenous insulin treatment. The FDA has not approved this treatment regimen as a comprehensive unit.

Regular human insulin, which has long been used off-label as an intravenous drip in the in-patient setting, especially intensive care units, acquired a labeled indication for intravenous use (Novolin R in 2005). On-label use, however, requires adequate monitoring:

INDICATIONS "Novolin R may be administered intravenously under proper medical supervision in a clinical setting for glycemic control";
DOSAGE AND ADMINISTRATION "Intramuscular and intravenous administrations of Novolin R are possible under medical supervision with close monitoring of blood glucose and potassium levels to avoid hypoglycemia and hypokalemia. For intravenous use, Novolin R should be used at concentrations from 0.05 U/ml to 1.0 U/ml in infusion systems with the infusion fluids 0.9% sodium chloride, 5% dextrose, or 10% dextrose with 40 mmol/l potassium chloride using polypropylene infusion bags."

The rapid-acting insulin analogues acquired the intravenous indication insulin aspart (Novolog) and glulisine (Apidra) respectively. The rapid onset of action for these agents occurs only because of more rapid transit through the skin. Onset of action is not more rapid through the intravenous or peritoneal routes of delivery. There are no approved computer systems for the input and integration of glucose and respiratory quotient data for either the determination of an insulin dose or for the determination of an insulin dose linked to a pumping mechanism.

VI. General Methodological Principles

When making national coverage determinations, CMS evaluates relevant clinical evidence to determine whether or not the evidence is of sufficient quality to support a finding that an item or service falling within a benefit category is reasonable and necessary for the diagnosis or treatment of illness or injury or to improve the functioning of a malformed body member. The critical appraisal of the evidence enables us to determine to what degree we are confident that: 1) the specific assessment questions can be answered conclusively; and 2) the intervention will improve health outcomes for patients. An improved health outcome is one of several considerations in determining whether an item or service is reasonable and necessary.

For diagnostic testing, CMS generally considers evidence in the hierarchical framework of Fryback and Thornbury (1991) where Level 2 addresses diagnostic accuracy, sensitivity, and specificity of the test; Level 3 focuses on whether the information changes the physician's diagnostic thinking; Level 4 concerns the effect on the patient management plan and Level 5 measures the effect of the diagnostic information on patient outcomes. Most studies have focused on test characteristics and changes in physician diagnostic thinking and have not considered health outcomes, such as mortality or morbidity. We believe that health outcomes are more important than test characteristics.

A detailed account of the methodological principles of study design that the agency utilizes to assess the relevant literature on a therapeutic or diagnostic item or service for specific conditions can be found in Appendix A. In general, features of clinical studies that improve quality and decrease bias include the selection of a clinically relevant cohort, the consistent use of a single good reference standard, and the blinding of readers of the index test and reference test results.

Public comment sometimes cites the published clinical evidence and gives CMS useful information. Public comments that give information on unpublished evidence such as the results of individual practitioners or patients are less rigorous and therefore less useful for making a coverage determination. CMS uses the initial public comments to inform its proposed decision. CMS responds in detail to the public comments on a proposed decision when issuing the final decision memorandum.

VII. Evidence

We are providing a summary of the evidence that we considered during our review. This section presents the agency's evaluation of the evidence considered for the assessment questions.

1. Is the evidence sufficient to conclude that an outpatient intravenous insulin therapy (OIVIT) regimen improves health outcomes in Medicare beneficiaries?

In order to answer question 1, we asked the following questions about the individual components that comprised OIVIT.

2. Do outpatient insulin treatment strategies that incorporate diagnostic respiratory quotient (RQ) testing to guide intravenous insulin therapy improve health outcomes compared to strategies that do not use RQ testing?
3. Do outpatient insulin treatment strategies that incorporate diagnostic urine urea nitrogen (UUN) testing to guide intravenous insulin therapy improve health outcomes compared to strategies that do not use UUN testing?
4. Do outpatient insulin treatment strategies that incorporate diagnostic blood glucose or potassium testing to guide intravenous insulin therapy improve health outcomes compared to strategies that do not use blood glucose or potassium testing?
5. If the answer to any of the above questions is affirmative,
   1. Which health outcomes of Medicare beneficiaries are improved?
   2. What is the duration of therapy required to effect a clinically significant improvement and how durable is that improvement (in the presence or absence of continued therapy)?
   3. Which patient characteristics reliably predict a clinically significant favorable or unfavorable health outcome?

Outcomes of greatest interest

Medicare is most interested in therapeutic modalities that have been shown to improve morbidity and mortality, i.e., hard clinical endpoints, in its beneficiaries. Reliance on intermediate (or surrogate) outcomes, such as change in test results, can be misleadingly encouraging.

For example, early studies in diabetes management led to hypotheses that hyperglycemia itself was the cause of diabetic complications such as neuropathy, retinopathy and macrovascular coronary artery disease. Thus, researchers focused on the improvement of glycemic control as a goal or desired outcome of treatment.

Indeed, the Diabetes Complications and Control Trial (DCCT) demonstrated that glycemic control could blunt the onset/progression of microvascular retinal and renal complications in Type 1 diabetic patients. ^{(DCCT 1993)} The United Kingdom Prospective Diabetes Study (UKPDS) suggested the same in Type 2 diabetic patients, but also indicated that the patient management of Type 2 diabetes with its impaired insulin action in combination with other metabolic defects involved more than insulin replacement. ^{(UKPDS 33, 34 1998)}

The subsequent studies by the Veterans’ Administration (VA) and the National Institutes of Health (NIH) have shown that intensive glycemic control using oral hypoglycemic medications and insulin does not confer major protection against cardiovascular disease and may increase morbidity and mortality.^{.(ACCORD Gerstein 2008, Skyler 2009, VA Abraira 1997, 2003, VA Duckworth 2009)} In addition, glycemic control has not been shown to reverse end-stage microvascular diabetic complications in either Type 1 or Type 2 patients and renal disease in Type 2 patients, when its underlying etiology is macrovascular or hypertensive in nature. ^{(Orchard 2006)}

Health outcomes of interest include improvements in the following morbidities of diabetes: retinal disease, microvascular renal complications, macrovascular renal disease and cardiovascular disease. Intermediate outcomes such as glycemic control, blood pressure control and blood pressure medication use are not accorded evidentiary weight for the reasons discussed above, as they can be misleading. Treatment burden and adverse effects, particularly severe hypoglycemia and any potential side effects attributable to the metabolic changes induced by the outpatient intravenous regimen of insulin administration such as alterations in serum lipids and lipid deposition in tissue are of interest because of the advanced age and co-morbid conditions present in many Medicare beneficiaries.

Health disparities
The Medicare beneficiary population includes several subgroups of diabetic patients. The largest segment (95+%) comprises older Type 2 diabetic patients (age 65+ years), whose primary cause of death is cardiovascular disease. Minority populations are overly represented in this diabetic population. Younger beneficiaries with Type 2 diabetes frequently have co-morbid conditions, e.g., psychiatric disease, which limit diabetes management. Younger beneficiaries with Type 1 disease are frequently in the Medicare program because they are already disabled by diabetes-related complications. As such, Medicare is interested in treatment modalities that address these complications and clinical conditions. ^{(MCAC 2006)}

B. Methods and Summary of Evidence Reviewed

CMS staff conducted a comprehensive search of materials to address the clinical questions delineated above. CMS staff extensively searched Medline (1965 to present) for primary studies evaluating pulsatile insulin and intravenous insulin therapy. The emphasis was on studies structured to assess long-term efficacy and adverse events. CMS staff likewise searched the Cochrane collection, the National Institute for Health and Clinical Excellence (United Kingdom) appraisals, and the Agency for Healthcare Research and Quality (United States) library for systematic reviews and technology assessments. Systematic reviews were sought to help locate any obscure publications and abstracts.

The CMS reviewed FDA reviews of the registration trials for intravenous insulin, intravenous pumps, glucose testing, and indirect calorimeters as well as FDA safety data for intravenous pumps and insulin. CMS staff reviewed the transcripts from the FDA Advisory Committee meetings on glucose monitoring systems, the warnings on glucose monitoring systems and the guidance document on 510k clearance for external infusion devices. CMS staff reviewed the 2008 NIH/FDA workshop proceedings about closed-loop insulin infusion systems. CMS searched the National Institutes of Health (NIH) Clinical Trials.gov database for ongoing/completed trials of outpatient intravenous insulin therapy. We used internet searches to identify websites with clinical trial results and/or pump information and/or respiratory quotient measurement information, press releases for clinical trials and/or pump information and calorimetry devices and U.S. government regulatory action. Preference was given to English language publications. Keywords used in the searches included: intravenous-insulin, pulsatile-insulin, hepatic activation, metabolic activation, calorimetry, respiratory quotient, metabolic cart, infusion pump and insulin pump.

We reviewed external technology assessments, evidence based guidelines, professional society position statements and public comments. We conducted an internal technology assessment of pertinent animal studies, exploratory physiologic studies in humans and longer-term clinical studies in patients. In addition, we reviewed eight trials listed in ClinicalTrials.gov.

We will consider additional evidence submitted through the 30-day public comment period on this proposed decision.

C. External Technology Assessments (TAs)

CMS did not commission an external TA for this NCA. We are aware of two external assessments of outpatient intravenous insulin treatment. We describe them below briefly.

1. Blue Cross/Blue Shield-California ^{(BCBS 2001)}
The therapeutic regimen was reviewed on February 14, 2001. The following was extracted from the assessment:
"Other alternatives to PIVIT exist for treatment of blood sugar, blood pressure, and kidney disease. Intensive insulin therapy has been documented to produce more sustained effects on glycemic control and antihypertensive therapy (particularly with ACE [angiotensin converting enzyme] inhibitors) to produce excellent control of blood pressure adequate to reduce or prevent progression of diabetic nephropathy. Based on the two randomized, controlled trials, it is difficult to conclude that PIVIT improves net health outcomes as much as or more than the established alternatives. Finally, the substantial drop-out rates in the randomized, controlled trials suggest that maintaining the schedule of weekly PIVIT in addition to daily intensive insulin needed to achieve its potential benefits may be difficult for many patients under conditions of usual medical practice. Therefore, TA criteria 2-5 are not met.

RECOMMENDATION It is recommended that pulsatile intravenous insulin therapy does not meet Blue Shield TA criteria for patients with type 1 diabetes mellitus."

2. Hayes (A proprietary technology assessment and rating firm in Landsdale, PA) ^{(Hayes 2007)} This therapeutic regimen was initially reviewed July 14, 2006 and subsequently updated August 15, 2007 and September 29, 2008. The following was extracted from the Executive Summary:
"Important questions regarding CIIIT are:

• Does CIIIT improve glycemic control and/or reduce incidence or progression of sequelae of diabetes, compared with conventional intensive insulin therapy?
• Is CIIIT safe?
• Have definitive patient selection criteria for CIIIT been established?"

"Major complications of CIIIT have not been reported.

Definitive patient selection criteria for CIIIT have not been established.

Conclusions: There is insufficient evidence from the limited number of published studies to conclude that CIIIT is effective in reducing symptoms, improving glycemic control, or preventing diabetic sequelae inpatients with type 1 diabetes. Although results of several of the studies suggest that CIIIT may improve glycemic control, facilitate blood pressure control, and/or slow progression of nephropathy, the lack of adequate controls, randomization, and blinding, and the small sample sizes of the available studies preclude definitive conclusions regarding the health benefit of CIIIT. Double-blind RCTs of adequate size are necessary to evaluate this therapy adequately."

D. Internal Technology Assessment
In this section, we describe and review the published studies (human physiologic and human clinical).

Published Studies: Exploratory Human Physiology Studies
There have been multiple physiologic studies of pulsatile insulin. (See Figure 6 and Table 1) They have been of short-term duration with testing occurring during treatment or immediately after 1-2 days of treatment. Normal subjects, Type 1 diabetic patients, and Type 2 diabetic patients have been tested. Similar to the animal studies discussed in the Background section, these studies used exogenous insulin as replacement for endogenous insulin and not as adjunctive therapy.

Figure 6: Published Human Physiology Studies

Table 2: Published Studies of Pulsatile IV Insulin: Exploratory and Physiologic: Human

Published Studies: Longer Clinical Trials
Clinical studies have been conducted by two groups of investigators: Aoki et al. and Dailey et al. (See Figure 6 and Table 3) Weinrauch et al. have studied a subset of the Dailey patient population more extensively. Unlike the physiology studies, these studies used exogenous insulin as replacement for endogenous insulin and not as adjunctive therapy. Non-standard endpoints were used in many of the studies. (Figure 7 and Table 3)

Figure 7: Clinical Studies of Outpatient Intravenous Insulin Therapy (OIVIT)

Table 3: Published Studies of Pulsatile IV Insulin: Extended Use: Human

Table 4: Randomized Clinical Studies of outpatient IV Insulin Therapy by Endpoint

There have been two semi-independent groups of researchers in this field. We have categorized the studies by research group and subcategorized the studies by topic or design features.

Aoki et al. Studies
Most of the studies conducted by Aoki and colleagues have been case series or retrospective studies without contemporaneous controls. (Tables 2, 3) ^{(Aoki 1993, 1995B, 1995C, and 1999)}

Non-randomized Studies

Randomized Studies (Aoki et al.)

Dailey et al. Studies
The studies conducted by Dailey et al. and Weinrauch et al. are related. (Figure 7, Table 2) The Weinrauch study population(s) are a subset of the Dailey population. (Figure 7, Table 2)

Randomized Studies (Dailey et al.)

Other Studies
We did not find published studies on the utility of pulsatile insulin in wound healing and amputation risk reduction.

We did not find published studies of pulsatile insulin in the peri-whole pancreas transplant or peri-islet transplant period despite published speculation about its utility. ^{(Mirabolooki 2009)}

E. Medicare Evidence Development and Coverage Advisory Committee (MEDCAC)

A MEDCAC meeting was not convened for this issue.

F. Evidence Based Guidelines
Numerous agencies and professional groups (Agency for Healthcare Research and Quality [AHRQ], American Association of Clinical Endocrinologists [AACE], American Association for Respiratory Care [AARC], American College of Cardiology [ACC], American College of Chest Physicians [ACCP], American College of Physicians [ACP], American Diabetes Association [ADA], American Dietetic Association [ADA], American Geriatrics Society [AGS], American Heart Association [AHA], American Thoracic Society [ATP], Canadian Diabetes Association [CDA], Endocrine Society, Juvenile Diabetes Research Foundation [JDRF], Scottish Intercollegiate Guidelines Network [SIGN], and Veterans Health Administration [VHA]) were queried about guidelines regarding intravenous insulin therapy and metabolic cart measurements. Many of these groups have a variety of guidelines for diabetes, nutrition, and cardiopulmonary disease management.

We found no evidence-based guidelines addressing the use of outpatient intravenous insulin therapy, the use of calorimetry to direct dosing or monitor intravenous insulin therapy in any type of patient, and/or the use of calorimetry in diabetic patients. Only the CDA addressed intravenous insulin and did so in the "In-hospital" chapter. "Role of Intravenous Insulin Infusion. Intravenous (IV) insulin infusion therapy should be considered during critical illness, or other illness requiring prompt glycemic control, or prolonged fasting (NPO status) (7). IV insulin infusion therapy should be administered only where frequent blood glucose (BG) monitoring and close nursing supervision are possible. Staff education is a critical component of the implementation of an IV insulin infusion protocol. IV insulin protocols should take into account the current and previous BG levels (and, therefore, the rate of change), and the patient’s usual insulin dose."

G. Professional Society Position Statements

American Association of Clinical Endocrinologists (AACE)
We received the following statement from the American Association of Clinical Endocrinologists (AACE).

American Diabetes Association (ADA)
The ADA issues positions statements, expert committee reports, workgroup reports, technical reviews, and consensus statements. Upon review, none of these documents address outpatient intravenous insulin, whether pulsatile or not. None of these documents address the use of calorimetry and respiratory quotients in managing diabetic patients.

Several years ago, the ADA was asked to assess the pulsatile insulin therapeutic program. The presented data were found not to be persuasive. (Communication with Richard Kahn, Ph.D., Scientific Director; September 2009)

Endocrine Society
The Endocrine Society does not have a position statement on outpatient IV insulin therapy.

Department of Defense
There are no centrally determined positions on insulin therapy. Pulsatile insulin therapy does not appear to have any/any significant use in the Army (Dr. Robert Vigersky; Walter Reed; personal communication) or the Navy (Dr. Patrick Clyde; National Naval Medical Center-Bethesda; personal communication March 2009)

Indian Health Service
Outpatient insulin therapy does not appear to have any/any significant use in the Indian Health Service (Dr. Susan Karol, chief medical officer for IHS; personal communication August 2009)

Veterans’ Health Systems
There are no centrally determined positions on insulin therapy. Pulsatile insulin therapy does not appear to have any /any significant use in the VA system (Dr. Leonard Pogach, Director-VA New Jersey Healthcare System, Center for Healthcare Knowledge Management; personal communication March 2009)

H. Expert Opinion
We expect to receive expert opinion on the proposed decision and will consider it in the final decision memorandum.

I. Public Comments
Public Comment Period: March 25, 2009 – April 24, 2009

Public comment sometimes cites the published clinical evidence and gives CMS useful information. Public comments that give information on unpublished evidence such as the results of individual practitioners or patients are less rigorous and therefore less useful for making a coverage determination. The CMS uses the initial public comments to inform its proposed decision. The CMS responds in detail to the public comments on a proposed decision when issuing the final decision memorandum.

During this initial public comment period, the CMS received a total of 187 comments from individuals/groups. The majority (n= 134) were patient testimonials about their own outpatient intravenous insulin treatment; three were testimonials in support of family members who had received outpatient intravenous insulin therapy. The remaining comments came from non-physician health care professionals (n= 21), physician clinicians (n= 17), academic physicians (n= 2); an attorney (n= 1), a health insurance industry representative (n= 1), and assorted or unspecified contributors. The majority favored CMS coverage of outpatient intravenous insulin therapy; five did not; two provided non-specific comments. Six provided literature citations and/or other materials with their comments but no new scientific publications were uncovered. Full text comments without personal health information can be viewed at: http://www.cms.hhs.gov/mcd/viewpubliccomments.asp?nca_id=231.

VIII. Analysis

Introduction
National coverage determinations (NCDs) are determinations by the Secretary with respect to whether or not a particular item or service is covered nationally under title XVIII of the Social Security Act §1869(f)(1)(B). In order to be covered by Medicare, an item or service must fall within one or more benefit categories contained within Part A or Part B, and must not be otherwise excluded from coverage. Moreover, with limited exceptions the expenses incurred for items or services must be "reasonable and necessary for the diagnosis or treatment of illness or injury or to improve the functioning of a malformed body member." See §1862(a)(1)(A) of the Act.

The Medicare regulations at 42 CFR 410.32(a) state in part, "…diagnostic tests must be ordered by the physician who is treating the beneficiary, that is, the physician who furnishes a consultation or treats a beneficiary for a specific medical problem and who uses the results in the management of the beneficiary’s specific medical problem." Thus we look for evidence demonstrating how the treating physician uses the result of a test, such as the respiratory quotient (RQ), for the management of a patient with diabetes who is undergoing intravenous insulin treatment and whether insulin treatment strategies that incorporate diagnostic respiratory quotient testing to guide insulin therapy improve health outcomes compared to strategies without RQ testing. This section presents the agency’s evaluation of the evidence considered and conclusions reached for the assessment.

Discussion
Outpatient intravenous insulin therapy (OIVIT) encompasses a large array of treatment regimens with associated services and testing. We recognize that various individual components of OIVIT may have medical uses in conventional treatment regimens for diabetes and other conditions. We are not in this decision making a coverage determination regarding those other various uses where these components are furnished outside of an OIVIT regimen. Coverage for such other uses may be determined by other local or national Medicare determinations and we will not consider them here.

The most commercial OIVIT procedure in the U.S. involves serial infusions of insulin in a pulsed fashion. The therapy is adjunctive to the patient’s usual diabetes management regimen. Metabolic cart measurements, specifically respiratory quotients, may be used for putative assessment of response to dosing and for determination of subsequent dosing. Multiple respiratory gas measurements for RQ measurements are often obtained on a single day.

CMS searched for evidence regarding OIVIT, including evidence pertaining to the use of its components in an OIVIT regimen. Although we focused on clinical trials, we did consider animal studies (See Background) and short-term/human physiology studies (See Evidence) because these types of studies are frequently used to establish primary efficacy, identify treatment protocol variables that impact efficacy, and identify patient or disease indication variables that impact efficacy prior to more extended clinical trials in human subjects.

Most of the animal and short-term/human physiology studies differed from therapeutic clinical studies in that the insulin dose was replacement dosing and not intermittent adjunctive dosing. Nonetheless, as in the three cited animal studies, the efficacy results in the short-term/human physiology studies were contradictory. Some studies demonstrated improved glycemic control or fuel utilization whereas others did not. Such inconsistency suggests the presence of important variables in regimen, technique, patient traits or disease state which require identification.

Investigators have not been able to determine which variables, whether intrinsic or experimental, except perhaps pulse rate, glucagon level and duration of infusion, contribute to these disparate results. ^{(Porksen 1998, Zarkovic 1999, 2000)} Respiratory quotients were seldom included in short-term/human physiology study protocols. As such, their role in future therapeutic clinical trial regimens was not clearly defined. ^{(Meistas 1985)}

CMS did identify nine published manuscripts for five studies in which outpatient IV insulin therapy was employed. The same proprietary treatment regimen was utilized. Only patients with diabetes were studied. Patient variables, (e.g., age, diabetes type, disease severity, and co-morbid conditions), or treatment variables, (e.g., pulse parameters, respiratory quotient response, and duration of therapy), which could impact therapeutic utility were not adequately addressed in the studies. None of the studies served as registration trials for FDA devices or drugs. No IND or IDE information was included in the methods sections.

All of these longer-term studies have significant limitations. Indeed, four manuscripts were based on populations that were subsets of larger study populations. None of the studies were blinded. Only two were randomized. Most were case series. This creates difficulty in determining whether the investigational treatment is comparable to conventional therapy and whether any apparent benefit is due to increased patient supervision/support.

All of the studies were small (n < 100). Total patient exposure in the studies was < 250 patients. Studies of sufficient duration to establish efficacy and/or durability were too small at initiation or through attrition or had design shortcomings. For example, analysis of only completers instead of all entrants in an intent-to-treat analysis can introduce selection bias. In addition, large differences in the clinical and demographic findings between the screened patient population and the entrant population limits generalizability. The small population also limits assessment of patient subgroups including those from different socioeconomic strata, ethnic/racial group, diabetes type, disease severity and co-morbid disease.

Only Type I diabetic patients were studied limiting generalizability to the Medicare patient population. No non-diabetic or perioperative islet cell transplant patients were studied, precluding generalizability of evidence to putative indications in those patient populations.

Many of the endpoints were subjective or poorly defined a priori. None were hard endpoints or non-surrogate endpoints. Several studies had numerous endpoints and reported on the variables that were statistically significant in completers (not the complete population). One study extended the length of the study until there was statistical significance. One study conducted the wrong statistical comparison. One study used a self-report survey tool developed by the progenitor of the pulsatile insulin regimen and not otherwise used/validated by diabetic researchers. ^{(Hammond 2004, Weinrauch 2009)} The investigators further modified this survey instrument when differences between treatment cohorts were absent when the complete scale was used. How hypoglycemia, hypokalemia and other adverse events were avoided was not adequately addressed. Safety data on lipids and organ/peri-organ lipid deposition were not presented. None of the studies were designed to identify and assess potentially important patient or treatment regimen variables for efficacy and safety.

Putative improvements in the rate of renal function decline, antihypertensive medication reduction, and perceived disability were not related to the glycemic control achieved with the treatment. No rationale for this epi-phenomenon was provided. Nor did the studies clarify why putative positive study results mediated by glycemic control could not be achieved through more standard therapy.

Algorithm information for use of the respiratory quotient was absent from the methods sections of all papers. No trials were structured to assess the role of the respiratory quotient either as a marker for efficacy or as a tool for subsequent insulin dosing. Response rates as indicated by an achievement of predetermined respiratory quotient thresholds or changes in respiratory quotients was not presented. Correlation of respiratory quotients or changes in respiratory quotients with clinical outcomes was not presented. No studies assessed the impact of scheduled or ad libitum carbohydrate ingestion or antecedent meal content on respiratory quotient measurements. ^{(Austin 2008, Benade 1973, Blundell 2002, Maffeis 2004, McGregor 1995, Root 1944, Talbott 1938)} No studies included urine collections as part of their respiratory quotient determinations. No studies addressed the absence of steady state conditions in the presence of glycosuria and albuminuria. No studies addressed factors that could affect the reliability and predictive value of the respiratory quotients such as technique requirements, device variability and standardization issues. None of the studies were structured to provide substantive information on the therapeutic intervention, on the variables that impact efficacy (if any), and the role of the respiratory quotient in directing the therapeutic regimen. None of the studies were structured to assess whether the urinary component (UUN) of RQ testing contributes to efficacy of any kind.

As such, CMS did not identify any high quality clinical trials for outpatient IV insulin therapy for any clinical indication. None of the studies clearly established any efficacy attributable to outpatient IV insulin therapy (versus increased insulin exposure and increased medical attention). None of the studies provided robust health outcome data of interest to the Medicare program (versus surrogate markers). None of the studies compared outpatient intravenous insulin treatment regimens with and without RQ testing (±UUN testing).

Moreover, CMS is concerned that the procedure is invasive and potentially burdensome to patients due to the perpetual weekly 6-hour sessions. CMS is also concerned that the monitoring for adverse events in the published trials was inadequate. Putative adverse events associated with alterations in glucose metabolism enzymes in the liver were not included in data collection. CMS is particularly concerned about the risk of hypoglycemia, especially in older beneficiaries with cardiovascular disease and co-morbidities when IV insulin is delivered undiluted from a pump syringe rather than via a diluted saline solution with a potassium piggy-backed solution.

Although this has been claimed to be standard therapy for glycemic control in a variety of diabetic patient populations and for control of diabetes-related complications, the available evidence does not support this. Other Federal health programs (Department of Defense, Indian Health Service, and the Veterans’ Affairs Health System) do not provide this therapeutic modality. No professional societies have included outpatient IV insulin therapy in their treatment guidelines or otherwise endorsed the therapeutic regimen. Only the ATS and ACCP have provided comments to CMS and these are tangentially related. Both societies stated that multiple determinations of the respiratory quotient in a single day are unwarranted.

Blue Cross/Blue Shield (California) and the Hayes Group have performed technology assessments of this therapeutic modality and concluded that the data did not support use of this treatment regimen. Many of the usual reviewers of technology, e.g., the Agency for Healthcare Research and Quality (AHRQ), the Cochrane Collaboration, and the National Institute for Health and Clinical Excellence (NICE), have not published technology assessments on outpatient intravenous insulin or metabolic cart measurements although they have conducted other assessments of diabetes-related technology and novel therapeutic regimens. The FDA has not approved or cleared the intravenous insulin treatment regimen, and no pumps have specifically been approved for this indication. The public commentors who advocated for CMS coverage did not provide scientific data that would support their position and many had conflicts of interest. Therefore, based on the evidence reviewed and analyzed, we conclude that OIVIT does not improve health outcomes in Medicare beneficiaries.

In summary, the evidence of record does not demonstrate that the use of OIVIT is reasonable and necessary to treat diabetes or any other medical condition. Moreover, the evidence of record does not demonstrate that the diagnostic tests RQ, UUN, diagnostic blood glucose or potassium testing performed in the context of OIVIT provide results that can be reasonably used by a physician in managing a patient with diabetes. Thus we are proposing to deny coverage of these specific components of OIVIT when furnished pursuant to an OIVIT regimen.

IX. Conclusion

1. The Centers for Medicare and Medicaid Services (CMS) proposes the following.

   The evidence is adequate to conclude that outpatient intravenous insulin therapy does not improve health outcomes in Medicare beneficiaries. Therefore, CMS has determined that outpatient intravenous insulin therapy is not reasonable and necessary for any indication under Section 1862(a)(1)(A) of the Social Security Act. Services comprising an Outpatient Intravenous Insulin Therapy regimen are nationally noncovered under Medicare when furnished pursuant to an outpatient intravenous insulin therapy regimen.

2. Outpatient Intravenous Insulin Therapy (OIVIT) consists of an outpatient regimen of pulsatile or continuous intravenous infusion of insulin via any means, guided by the results of:

General Methodological Principles of Study Design

When making national coverage determinations, CMS evaluates relevant clinical evidence to determine whether or not the evidence is of sufficient quality to support a finding that an item or service is reasonable and necessary. The overall objective for the critical appraisal of the evidence is to determine to what degree we are confident that: 1) the specific assessment questions can be answered conclusively; and 2) the intervention will improve health outcomes for patients.

We divide the assessment of clinical evidence into three stages: 1) the quality of the individual studies; 2) the generalizability of findings from individual studies to the Medicare population; and 3) overarching conclusions that can be drawn from the body of the evidence on the direction and magnitude of the intervention’s potential risks and benefits.

The methodological principles described below represent a broad discussion of the issues we consider when reviewing clinical evidence. However, it should be noted that each coverage determination has its unique methodological aspects.

Assessing Individual Studies

Methodologists have developed criteria to determine weaknesses and strengths of clinical research. Strength of evidence generally refers to: 1) the scientific validity underlying study findings regarding causal relationships between health care interventions and health outcomes; and 2) the reduction of bias. In general, some of the methodological attributes associated with stronger evidence include those listed below:

• Use of randomization (allocation of patients to either intervention or control group) in order to minimize bias.
• Use of contemporaneous control groups (rather than historical controls) in order to ensure comparability between the intervention and control groups.
• Prospective (rather than retrospective) studies to ensure a more thorough and systematical assessment of factors related to outcomes.
• Larger sample sizes in studies to demonstrate both statistically significant as well as clinically significant outcomes that can be extrapolated to the Medicare population. Sample size should be large enough to make chance an unlikely explanation for what was found.
• Masking (blinding) to ensure patients and investigators do not know to which group patients were assigned (intervention or control). This is important especially in subjective outcomes, such as pain or quality of life, where enthusiasm and psychological factors may lead to an improved perceived outcome by either the patient or assessor.

Regardless of whether the design of a study is a randomized controlled trial, a non-randomized controlled trial, a cohort study or a case-control study, the primary criterion for methodological strength or quality is the extent to which differences between intervention and control groups can be attributed to the intervention studied. This is known as internal validity. Various types of bias can undermine internal validity. These include:

• Different characteristics between patients participating and those theoretically eligible for study but not participating (selection bias).
• Co-interventions or provision of care apart from the intervention under evaluation (performance bias).
• Differential assessment of outcome (detection bias).
• Occurrence and reporting of patients who do not complete the study (attrition bias).

In principle, rankings of research design have been based on the ability of each study design category to minimize these biases. A randomized controlled trial minimizes systematic bias (in theory) by selecting a sample of participants from a particular population and allocating them randomly to the intervention and control groups. Thus, in general, randomized controlled studies have been typically assigned the greatest strength, followed by non-randomized clinical trials and controlled observational studies. The design, conduct and analysis of trials are important factors as well. For example, a well designed and conducted observational study with a large sample size may provide stronger evidence than a poorly designed and conducted randomized controlled trial with a small sample size. The following is a representative list of study designs (some of which have alternative names) ranked from most to least methodologically rigorous in their potential ability to minimize systematic bias:

• Randomized controlled trials
• Non-randomized controlled trials
• Prospective cohort studies
• Retrospective case control studies
• Cross-sectional studies
• Surveillance studies (e.g., using registries or surveys)
• Consecutive case series
• Single case reports

When there are merely associations but not causal relationships between a study’s variables and outcomes, it is important not to draw causal inferences. Confounding refers to independent variables that systematically vary with the causal variable. This distorts measurement of the outcome of interest because its effect size is mixed with the effects of other extraneous factors. For observational, and in some cases randomized controlled trials, the method in which confounding factors are handled (either through stratification or appropriate statistical modeling) are of particular concern. For example, in order to interpret and generalize conclusions to our population of Medicare patients, it may be necessary for studies to match or stratify their intervention and control groups by patient age or co-morbidities.

Methodological strength is, therefore, a multidimensional concept that relates to the design, implementation and analysis of a clinical study. In addition, thorough documentation of the conduct of the research, particularly study selection criteria, rate of attrition and process for data collection, is essential for CMS to adequately assess and consider the evidence.

Generalizability of Clinical Evidence to the Medicare Population

The applicability of the results of a study to other populations, settings, treatment regimens and outcomes assessed is known as external validity. Even well-designed and well-conducted trials may not supply the evidence needed if the results of a study are not applicable to the Medicare population. Evidence that provides accurate information about a population or setting not well represented in the Medicare program would be considered but would suffer from limited generalizability.

The extent to which the results of a trial are applicable to other circumstances is often a matter of judgment that depends on specific study characteristics, primarily the patient population studied (age, sex, severity of disease and presence of co-morbidities) and the care setting (primary to tertiary level of care, as well as the experience and specialization of the care provider). Additional relevant variables are treatment regimens (dosage, timing and route of administration), co-interventions or concomitant therapies, and type of outcome and length of follow-up.

The level of care and the experience of the providers in the study are other crucial elements in assessing a study’s external validity. Trial participants in an academic medical center may receive more or different attention than is typically available in non-tertiary settings. For example, an investigator’s lengthy and detailed explanations of the potential benefits of the intervention and/or the use of new equipment provided to the academic center by the study sponsor may raise doubts about the applicability of study findings to community practice.

Given the evidence available in the research literature, some degree of generalization about an intervention’s potential benefits and harms is invariably required in making coverage determinations for the Medicare population. Conditions that assist us in making reasonable generalizations are biologic plausibility, similarities between the populations studied and Medicare patients (age, sex, ethnicity and clinical presentation) and similarities of the intervention studied to those that would be routinely available in community practice.

A study’s selected outcomes are an important consideration in generalizing available clinical evidence to Medicare coverage determinations. One of the goals of our determination process is to assess health outcomes. These outcomes include resultant risks and benefits such as increased or decreased morbidity and mortality. In order to make this determination, it is often necessary to evaluate whether the strength of the evidence is adequate to draw conclusions about the direction and magnitude of each individual outcome relevant to the intervention under study. In addition, it is important that an intervention’s benefits are clinically significant and durable, rather than marginal or short-lived. Generally, an intervention is not reasonable and necessary if its risks outweigh its benefits.

If key health outcomes have not been studied or the direction of clinical effect is inconclusive, we may also evaluate the strength and adequacy of indirect evidence linking intermediate or surrogate outcomes to our outcomes of interest.

Assessing the Relative Magnitude of Risks and Benefits

Generally, an intervention is not reasonable and necessary if its risks outweigh its benefits. Health outcomes are one of several considerations in determining whether an item or service is reasonable and necessary. CMS places greater emphasis on health outcomes actually experienced by patients, such as quality of life, functional status, duration of disability, morbidity and mortality, and less emphasis on outcomes that patients do not directly experience, such as intermediate outcomes, surrogate outcomes, and laboratory or radiographic responses. The direction, magnitude, and consistency of the risks and benefits across studies are also important considerations. Based on the analysis of the strength of the evidence, CMS assesses the relative magnitude of an intervention or technology’s benefits and risk of harm to Medicare beneficiaries.

The CDA guideline section on intravenous insulin is delineated in the "In-hospital” chapter.
"Role of Intravenous Insulin Infusion. Intravenous (IV) insulin infusion therapy should be considered during critical illness, or other illness requiring prompt glycemic control, or prolonged fasting (NPO status) (7). IV insulin infusion therapy should be administered only where frequent blood glucose (BG) monitoring and close nursing supervision are possible.  Staff education is a critical component of the implementation of an IV insulin infusion protocol.  IV insulin protocols should take into account the current and previous BG levels (and, therefore, the rate of change), and the patient’s usual insulin dose.”
