Updates to the Standards of Medical Care in Diabetes

Jump to:
June 3, 2019 Updates (CREDENCE and CANVAS Trials—10. Cardiovascular Disease and Risk Management, 11. Microvascular Complications and Foot Care)
April 18, 2019 Updates (Nutrition Therapy Consensus Statement—5. Lifestyle Management)
March 27, 2019 Updates (DECLARE-TIMI 5 and REDUCE-IT—9. Pharmacologic Approaches to Glycemic Treatment,  10. Cardiovascular Disease and Risk Management, 11. Microvascular Complications and Foot Care)
2018 Updates (2018 updates incorporated into the 2019 Standards of Care)

The American Diabetes Association’s (ADA’s) Standards of Medical Care in Diabetes (Standards of Care) provide the latest in comprehensive, evidence-based recommendations for the diagnosis and treatment of children and adults with type 1, type 2 or gestational diabetes; strategies to prevent or delay type 2 diabetes; and therapeutic approaches that reduce complications and positively affect health outcomes. The Standards of Care is a “living” document where notable updates are incorporated as determined appropriate and voted on by the Professional Practice Committee (PPC). Updates are made in response to important events such as approval of new treatments (medications or devices) with the potential to impact patient care, publication of new findings that support a change to a recommendation and/or evidence level of a recommendation, or publication of a consensus document endorsed by ADA that necessitates an update of the Standards to align content of the documents. The updating process allows the online version (and downloadable PDF) to be updated and revised throughout the year by adding annotations to the Standards of Care published in Diabetes Care and the abridged Standards of Care publishing in Clinical Diabetes. For each “living” Standards update, ADA notifies providers and stakeholders through various communication channels (emails, websites, social medical, etc.) and revises the Standards of Care slide deck, Standards of Care app, professional education programs, and selected other materials to be consistent with living Standards of Care updates.

June 3, 2019
Today, we have issued important updates to the 2019 Standards of Care focused on improving cardiovascular and renal health in people with type 2 diabetes. Section 10, Cardiovascular Disease and Risk Management and Section 11, Microvascular Complications and Foot Care were updated based on findings from the Canagliflozin and Renal Outcomes in Type 2 Diabetes and Nephropathy (CREDENCE) trial, which was published on April 14, 2019, in the New England Journal of Medicine (https://doi.org/10.1056/NEJMoa1811744). The CREDENCE trial assessed the impact of canagliflozin therapy on cardiorenal outcomes in patients with diabetes-related chronic kidney disease. The updates are as follows.

Section 10. Cardiovascular Disease and Risk Management

The third paragraph of the subsection “Antihyperglycemic Therapies and Cardiovascular Outcomes” is edited and lengthened to incorporate findings from the Canagliflozin and Renal Events in Diabetes with Established Nephropathy Clinical Evaluation (CREDENCE) trial, as follows:

  • UPDATE: "Two large outcome trials of the SGLT2 inhibitor canagliflozin have been conducted, which separately assessed the cardiovascular effects of treatment in patients at high risk for major adverse cardiovascular events, and the impact of canagliflozin therapy on cardiorenal outcomes in patients with diabetes-related chronic kidney disease. First, the Canagliflozin Cardiovascular Assessment Study (CANVAS) program integrated data from two trials. The CANVAS trial that started in 2009 was partially unblinded prior to completion because of the need to file interim cardiovascular outcomes data for regulatory approval of the drug (158). Thereafter, the post-approval CANVAS-Renal (CANVAS-R) trial was started in 2014. Combining both of these trials, 10,142 participants with type 2 diabetes were randomized to canagliflozin or placebo and were followed for an average 3.6 years. The mean age of patients was 63 years and 66% had a history of cardiovascular disease. The combined analysis of the two trials found that canagliflozin significantly reduced the composite outcome of cardiovascular death, MI, or stroke versus placebo (occurring in 26.9 vs. 31.5 participants per 1,000 patient-years; HR 0.86 [95% CI 0.75-0.97]). The specific estimates for canagliflozin versus placebo on the primary composite cardiovascular outcome were HR 0.88 (0.75-1.03) for the CANVAS trial and 0.82 (0.66-1.01) for CANVAS-R, with no heterogeneity found between trials. Of note, there was an increased risk of lower-limb amputation with canagliflozin (6.3 vs. 3.4 participants per 1,000 patient-years; HR 1.97 [95% CI 1.41-2.75]) (9). Second, the Canagliflozin and Renal Events in Diabetes with Established Nephropathy Clinical Evaluation (CREDENCE) trial randomized 4,401 patients with type 2 diabetes and chronic diabetes-related kidney disease (UACR >300 mg/g, and eGFR 30 to <90 mL/min/1.73 m2) to canagliflozin 100 mg daily or placebo (Perkovic 2019). The primary outcome was a composite of end-stage kidney disease (ESKD), doubling of serum Cr, or death from renal or cardiovascular causes. The trial was stopped early due to conclusive evidence of efficacy identified during a pre-specified interim analysis with no unexpected safety signals. The risk of the primary composite outcome was 30% lower with canagliflozin treatment when compared with placebo (HR 0.70 [95% CI 0.59-0.82]). Moreover, it reduced the prespecified endpoint of ESKD alone by 32% (HR=0.68 [95%CI 0.54-0.86]). Canagliflozin was additionally found to have a lower risk of the composite of cardiovascular death, myocardial infarction, or stroke (HR 0.80  [95% CI 0.67-0.95]), as well as lower risk of hospitalizations for heart failure (HR 0.61 [95% CI 0.47 – 0.80]), and of the composite of cardiovascular death or hospitalization for heart failure (HR 0.69 [95% CI 0.57 – 0.83]). In terms of safety, no significant increase in lower-limb amputations, fractures, acute kidney injury, or hyperkalemia were noted for canagliflozin relative to placebo in CREDENCE. An increased risk for diabetic ketoacidosis (DKA) was noted, however, with 2.2 and 0.2 events per 1,000 patient-years noted in the canagliflozin and placebo groups, respectively (HR 10.80 [95% CI 1.39-83.65]) (Perkovic 2019). Please refer to Table 9.1 for drug-specific factors, including adverse event information, for these agents."

The fourth paragraph of the subsection “Antihyperglycemic Therapies and Heart Failure” is edited to incorporate findings from the Canagliflozin and Renal Events in Diabetes with Established Nephropathy Clinical Evaluation (CREDENCE) trial.

  • UPDATE: "Reduced incidence of heart failure has been observed with the use of SGLT2 inhibitors. In EMPA-REG OUTCOME, the addition of empagliflozin to standard care led to a significant 35% reduction in hospitalization for heart failure compared with placebo (8). Although the majority of patients in the study did not have heart failure at baseline, this benefit was consistent in patients with and without a history of heart failure (172). Similarly, in CANVAS and DECLARE-TIMI 58, there were 33% and 27% reductions in hospitalization for heart failure, respectively, with SGLT2 inhibitor use versus placebo (9, DECLARE-TIMI 58). Additional data from the CREDENCE trial with canagliflozin showed a 39% reduction in hospitalization for heart failure, and 31% reduction in the composite of cardiovascular death or hospitalization for heart failure, in a diabetic kidney disease population with albuminuria (UACR of >300 to 5,000 mg/g) (Perkovic 2019). These combined findings from four large outcomes trials of three different SGLT-2 inhibitors are highly consistent, and clearly indicate robust benefits of SGLT2 inhibitors in the prevention of heart failure hospitalizations. They also suggest (but do not prove) that SGLT-2 inhibitors may be beneficial in patients with established HF. This hypothesis is being specifically evaluated in several large outcome trials in patients with established heart failure, both with and without diabetes, to determine the efficacy of SGLT-2 inhibitors in the treatment of heart failure with reduced and preserved ejection fraction."

Section 11. Microvascular Complications and Foot Care

Recommendations have been updated based on findings from the Canagliflozin and Renal Events in Diabetes with Established Nephropathy Clinical Evaluation (CREDENCE) trial, as follows:

  • UPDATE: 11.1 At least once a year, assess urinary albumin (e.g., spot urinary albumin-to-creatine ratio) and estimated glomerular filtration rate in patients with type 1 diabetes with duration of ≥5 years, in all patients with type 2 diabetes, regardless of treatment, and in all patients with comorbid hypertension. B
     
  • UPDATE: 11.3 For patients with type 2 diabetes and diabetic kidney disease, consider use of a sodium-glucose cotransporter 2 inhibitor in patients with an eGFR ≥ 30 and particularly in those with >300 mg/g albuminuria to reduce risk of CKD progression, cardiovascular events, or both. A In patients with CKD who are at increased risk for CV events, use of a glucagon-like peptide 1 receptor agonist may reduce risk of progression of albuminuria, cardiovascular events, or both (Table 9.1). C
     
  • UPDATE: 11.8 Based on findings from the Canagliflozin and Renal Events in Diabetes with Established Nephropathy Clinical Evaluation (CREDENCE) trial, recommendation 11.8 in Section 11. Microvascular Complications and Foot Care has been removed and is no longer a recommendation.

Based on findings from the Canagliflozin and Renal Endpoints in Diabetes with Established Nephropathy Clinical Evaluation (CREDENCE) trial, the 6th paragraph of the sub-section “Selection of Glucose-Lowering Medications for Patients with Chronic Kidney Disease” has been edited to update the existing paragraph discussing the CREDENCE trial:

  • UPDATE: "Several large clinical trials of SGLT2 inhibitors focused on patients with CKD, and assessment of primary renal outcomes are completed or ongoing. Canagliflozin and Renal Endpoints in Diabetes with Established Nephropathy Clinical Evaluation (CREDENCE), a placebo-controlled trial of canagliflozin among 4,401 adults with type 2 diabetes, UACR ≥300 mg/g, and EGFR 30-90 mL/min/1.73m2, had a primary composite end point of ESRD, doubling of serum Cr, or renal or cardiovascular death (54; Perkovic 2019). CREDENCE was stopped early following a planned interim analysis due to conclusive evidence of efficacy. The risk of the primary composite outcome was 30% lower with canagliflozin treatment when compared with placebo (HR 0.70 [95% CI 0.59-0.82]). In addition, the risk of the renal-specific composite outcome of ESRD, doubling of serum Cr, and death from renal causes was lower by 34% in the canagliflozin group compared with placebo (HR 0.66 [95% CI 0.53-0.81]). Importantly, the renal and cardiovascular risk reduction observed in CREDENCE was present in patients with an eGFR in the 30-45 ml/min/1.73m2 range. Although the adverse event profiles of these agents must be considered, the risk-benefit balance of SGLT-2 inhibitor treatment appears to be favorable for most patients with type 2 diabetes and CKD. No increased risk of lower-limb amputations, fractures, acute kidney injury, or hyperkalemia were noted for canagliflozin relative to placebo in CREDENCE. An increased risk for diabetic ketoacidosis (DKA) was noted, however, with 2.2 and 0.2 events per 1000 patient-years noted in the canagliflozin and placebo groups, respectively (HR 10.80 [95% CI 1.39-83.65]) (Perkovic 2019). Please refer to Table 9.1 for drug-specific factors, including adverse event information, for these agents."

Based on findings from the Canagliflozin and Renal Endpoints in Diabetes with Established Nephropathy Clinical Evaluation (CREDENCE) trial, the 8th paragraph of the sub-section “Selection of Glucose-Lowering Medications for Patients with Chronic Kidney Disease” has been edited to acknowledge findings from CREDENCE:

  • UPDATE: "Findings from CREDENCE provide important evidence that canagliflozin use in patients with type 2 diabetes and albuminuric (UACR >300 mg/g) DKD decreased the risk of the renal-specific composite outcome (inclusive of ESKD, doubling of the creatinine level, or death from renal causes) by an additional 34% over standard of care with over 99% of people being on a renin angiotensin system blocker with good BP and glycemic control. Moreover, there were significant reductions in cardiovascular events, including MACE and hospitalizations for heart failure (Perkovic 2019). Although the adverse event profiles of these agents must be considered, the risk-benefit balance of SGLT-2 inhibitor treatment appears to be favorable for most patients with type 2 diabetes and CKD. Please refer to Table 9.1 for drug-specific factors, including adverse event information, for these agents. Clinical trials currently in progress will provide additional insight into the benefits and risks of these classes of drugs among people with CKD."

April 18, 2019
In 2018 ADA issued a nationwide call for experts to review the latest research on nutrition therapy for diabetes. The resulting writing group prepared a nutrition Consensus Report intended to update and replace the 2014 ADA nutrition Position Statement. The Consensus Report panel performed a comprehensive review of more than 600 key nutrition manuscripts published from 2014 through 2018. The resulting recommendations focus on key areas of nutrition management and guidelines to achieve optimal diabetes management, reduce complications, and improve quality of life for adults with type 1 or type 2 diabetes or prediabetes. The new nutrition consensus report is published online ahead of print and in the May issue of Diabetes Care (available April 22, 2019) in a special section titled “The Continuing Evolution of Nutritional Therapy for Diabetes.” Recommendations from this latest Consensus Report are included as updates to the Standards of Care. The April 18 Living Standards of Care updates:

5. Lifestyle Management: Standards of Medical Care in Diabetes—2019 

Section 5 is updated based on information provided in the ADA document titled: "Nutrition Therapy for Adults with Diabetes or Prediabetes: A Consensus Report" per below.

  • UPDATE: The highlighted paragraph in the section titled: "Eating Patterns, Macronutrient Distribution, and Meal Planning" is updated to state the following: “Evidence suggests that there is not an ideal percentage of calories from carbohydrate, protein, and fat for all people with diabetes. Therefore, macronutrient distribution should be based on an individualized assessment of current eating patterns, preferences, and metabolic goals. Consider personal preferences (e.g., tradition, culture, religion, health beliefs and goals, economics) as well as metabolic goals when working with individuals to determine the best eating pattern for them (35,51,52). It is important that each member of the health care team be knowledgeable about nutrition therapy principles for people with all types of diabetes and be supportive of their implementation. A variety of eating patterns are acceptable for the management of diabetes (51,54). Until the evidence surrounding comparative benefits of different eating patterns in specific individuals strengthens, health care providers should focus on the key factors that are common among the patterns: 1) emphasize nonstarchy vegetables, 2) minimize added sugars and refined grains, and 3) choose whole foods over highly processed foods to the extent possible (Evert 2019).  Referral to an RD or registered dietitian nutritionist (RDN) is essential to assess the overall nutrition status of, and to work collaboratively with, the patient to create a personalized meal plan that considers the individual’s health status, skills, resources, food preferences, and health goals to coordinate and align with the overall treatment plan including physical activity and medication. The Mediterranean-style (55,56), low-carbohydrate (add 2 references) and plant-based (60,61) eating patterns are all examples of healthful eating patterns that have shown positive results in research, but individualized meal planning should focus on personal preferences, needs, and goals. Reducing overall carbohydrate intake for individuals with diabetes has demonstrated the most evidence for improving glycemia and may be applied in a variety of eating patterns that meet individual needs and preferences. For individuals with type 2 diabetes not meeting glycemic targets or where reducing glucose-lowering drugs is a priority, reducing overall carbohydrate intake with a low- or very low-carbohydrate eating pattern is a viable option. (Sainsbury 2018, van Zuuren 2018, Snorgaard 2017). As research studies on some low-carbohydrate eating plans generally indicate challenges with long-term sustainability, it is important to reassess and individualize meal plan guidance regularly for those interested in this approach. This eating pattern is not recommended at this time for women who are pregnant or lactating, people with or at risk for disordered eating, or people who have renal disease, and it should be used with caution in patients taking sodium–glucose cotransporter 2 (SGLT2) inhibitors due to the potential risk of ketoacidosis (65,66). There is inadequate research in type 1 diabetes to support one eating pattern over another at this time.”

  • UPDATE: The first highlighted paragraph in the section "Weight Management" is updated to state the following: “Management and reduction of weight is important for people with type 1 diabetes, type 2 diabetes, or prediabetes who have overweight or obesity. To support weight loss and improve A1C, CVD risk factors, and quality of life in adults with overweight/obesity and prediabetes or diabetes, MNT and DSMES services should include an individualized eating plan in a format that results in an energy deficit in combination with enhanced physical activity (Evert 2019). Lifestyle intervention programs should be intensive and have frequent follow-up to achieve significant reductions in excess body weight and improve clinical indicators. There is strong and consistent evidence that modest persistent weight loss can delay the progression from prediabetes to type 2 diabetes (51,68,69) (see Section 3 “Prevention or Delay of Type 2 Diabetes”) and is beneficial to the management of type 2 diabetes (see Section 8 “Obesity Management for the Treatment of Type 2 Diabetes”).”

  • UPDATE: The second highlighted paragraph in the section "Weight Management"is updated to state the following: “In prediabetes, the weight loss goal is 7–10% for preventing progression to type 2 diabetes (Hamman 2006). In conjunction with lifestyle therapy, medication-assisted weight loss can be considered for people at risk for type 2 diabetes when needed to achieve and sustain 7–10% weight loss (Carlsson 2012, Booth 2014). People with prediabetes at a healthy weight should be considered for lifestyle intervention involving both aerobic and resistance exercise (Hamman 2006, Jeon 2007, Duncan 2003) and a healthy eating plan such as a Mediterranean-style eating pattern (75). For many overweight and obese individuals with type 2 diabetes, 5% weight loss is needed to achieve beneficial outcomes in glycemic control, lipids, and blood pressure (70). It should be noted, however, that the clinical benefits of weight loss are progressive, and more intensive weight loss goals (i.e., 15%) may be appropriate to maximize benefit depending on need, feasibility, and safety (73, Wing 2011). In select individuals with type 2 diabetes, an overall healthy eating plan that results in energy deficit in conjunction with weight loss medications and/or metabolic surgery should be considered to help achieve weight loss and maintenance goals, lower A1C, and reduce CVD risk (Sjöström 2014, Garvey 2014, Cefalu 2015). Overweight and obesity are also increasingly prevalent in people with type 1 diabetes and present clinical challenges regarding diabetes treatment and CVD risk factors (Prinz 2018, Lipman 2013). Sustaining weight loss can be challenging (70,71) but has long-term benefits; maintaining weight loss for 5 years is associated with sustained improvements in A1C and lipid levels (72). MNT guidance from an RD/RDN with expertise in diabetes and weight management, throughout the course of a structured weight loss plan, is strongly recommended. People with diabetes and prediabetes should be screened and evaluated during DSMES and MNT encounters for disordered eating, and nutrition therapy should accommodate these disorders (Evert 2019).”

  • UPDATE: The last highlighted paragraph in the section "Carbohydrates" has been changed to state the following: “Individuals with type 1 or type 2 diabetes taking insulin at mealtime should be offered intensive and ongoing education on the need to couple insulin administration with carbohydrate intake. For people whose meal schedule or carbohydrate consumption is variable, regular counseling to help them understand the complex relationship between carbohydrate intake and insulin needs is important. In addition, education on using the insulin-to-carbohydrate ratios for meal planning can assist them with effectively modifying insulin dosing from meal to meal and improving glycemic control (51,82,93–96). Results from recent high-fat and/or high-protein mixed meals studies continue to support previous findings that glucose response to mixed meals high in protein and/or fat along with carbohydrate differ among individuals; therefore a cautious approach to increasing insulin doses for high-fat and/or high-protein mixed meals is recommended to address delayed hyperglycemia that may occur 3 h or more after eating (Evert 2019).  Checking glucose 3 h after eating may help to determine if additional insulin adjustments are required (Bell 2016, Campbell 2016). Continuous glucose monitoring (CGM) or self-monitoring of blood glucose (SMBG) should guide decision-making for administration of additional insulin. For individuals on a fixed daily insulin schedule, meal planning should emphasize a relatively fixed carbohydrate consumption pattern with respect to both time and amount (35).”

March 27, 2019—Atherosclerotic cardiovascular disease (ASCVD) is the leading cause of morbidity and mortality for individuals with diabetes, and heart disease is the cause of one in four deaths in the U.S. Diabetes is the leading cause of chronic kidney disease, and approximately one out of four adults with diabetes has kidney disease. Recently published research indicated an urgent need to update the 2019 Standards of Care to ensure optimal treatment recommendations for people with cardiovascular disease and diabetes, and for those with chronic kidney disease and diabetes. The March 27 Living Standards of Care updates:

  • Section 10 is updated based on the outcome of Reduction of Cardiovascular Events with Icosapent Ethyl–Intervention Trial (REDUCE-IT), which determined the addition of icosapent ethyl to statin therapy for patients with high triglyceride levels reduced cardiovascular events. The Standards of Care now include a recommendation that icosapent ethyl be considered for patients with diabetes and atherosclerotic cardiovascular disease (ASCVD) or other cardiac risk factors on a statin with controlled LDL-C, but with elevated triglycerides (135-499) to reduce cardiovascular risk.
     
  • Sections 9, 10, and 11 are revised based on findings from The Dapagliflozin Effect on Cardiovascular Events-Thrombosis in Myocardial Infarction 58 (DECLARE-TIMI 58) Trial, in which dapagliflozin treatment showed a reduction of hospitalization for heart failure and a reduction in progression of chronic kidney disease (CKD).
     
  • Based on a revision to the prescribing information for dapagliflozin, for patients with diabetes and CKD, the approved use per estimated glomerular filtration rate (eGFR) is revised from ≥60 mL/min/1.73 m2 to ≥45 mL/min/1.73 m2 in Section 11 of the Standards of Care.
