7 STANDARDS OF MEDICAL CARE IN DIABETES 2015

8 ADA Evidence Grading System for Clinical Practice Recommendations Level of Evidence A B C E Description Clear or supportive evidence from adequately powered well-conducted, generalizable, randomized controlled trials Compelling nonexperimental evidence Supportive evidence from well-conducted cohort studies or case-control study Supportive evidence from poorly controlled or uncontrolled studies Conflicting evidence with the weight of evidence supporting the recommendation Expert consensus or clinical experience ADA. Diabetes Care 2015;38(suppl 1):S2; Table 1

9 Recommendations: Strategies for Improving Diabetes Care Care should be aligned with components of the Chronic Care Model to ensure productive interactions between a prepared proactive practice team and an informed activated patient A When feasible, care systems should support teambased care, community involvement, patient registries, and embedded decision support tools to meet patient needs B Physicians, nurse practitioners, physician s assistants, nurses, dietitians, pharmacists, mental health professionals, CDE In this collaborative and integrated team approach, essential that individuals with diabetes assume an active role in their care ADA. 1. Strategies for Improving Diabetes Care. Diabetes Care 2015;38(suppl 1):S5

10 CLASSIFICATION AND DIAGNOSIS OF DIABETES

11 Type 1 diabetes β-cell destruction Type 2 diabetes Classification of Diabetes Progressive insulin secretory defect Other specific types of diabetes Genetic defects in β-cell function, insulin action (MODY) Diseases of the exocrine pancreas (CFRD) Drug- or chemical-induced Gestational diabetes mellitus (GDM) ADA. 2. Classification and Diagnosis. Diabetes Care 2015;38(suppl 1):S8

12 Criteria for the Diagnosis of Diabetes A1C 6.5% OR Fasting plasma glucose (FPG) 126 mg/dl (7.0 mmol/l) OR 2-h plasma glucose 200 mg/dl (11.1 mmol/l) during an OGTT OR A random plasma glucose 200 mg/dl (11.1 mmol/l) ADA. 2. Classification and Diagnosis. Diabetes Care 2015;38(suppl 1):S9; Table 2.1

13 Categories of Increased Risk for Diabetes (Prediabetes)* FPG mg/dl ( mmol/l): IFG OR 2-h plasma glucose in the 75-g OGTT mg/dl ( mmol/l): IGT OR A1C % *For all three tests, risk is continuous, extending below the lower limit of a range and becoming disproportionately greater at higher ends of the range. ADA. 2. Classification and Diagnosis. Diabetes Care 2015;38(suppl 1):S10; Table 2.3

14 Recommendations: Testing for Diabetes in Asymptomatic Patients Consider testing overweight/obese adults (BMI 25 kg/m 2 or 23 kg/m 2 in Asian Americans) with one or more additional risk factors for type 2 diabetes; for all patients, particularly those who are overweight, testing should begin at age 45 years B If tests are normal, repeat testing at least at 3-year intervals is reasonable C To test for diabetes/prediabetes, the A1C, FPG, or 2-h 75-g OGTT are appropriate B In those with prediabetes, monitor for development of diabetes annually E ADA. 2. Classification and Diagnosis. Diabetes Care 2015;38(suppl 1):S11

15 PREVENTION/DELAY OF TYPE 2 DIABETES

16 Recommendations: Prevention/Delay of Type 2 Diabetes Diabetes Prevention Program Targeting weight loss of 7% of body weight Increasing physical activity to at least 150 min/week of moderate activity (eg, walking) Follow-up counseling appears to be important for success Based on cost-effectiveness of diabetes prevention, such programs should be covered by third-party payers ADA. 5. Prevention/Delay of Type 2 Diabetes. Diabetes Care 2015;38(suppl 1):S31

17 GLYCEMIC TARGETS

18 Diabetes Care: Glycemic Control Two primary techniques available for health providers and patients to assess effectiveness of management plan on glycemic control Patient self-monitoring of blood glucose (SMBG), or interstitial glucose A1C Perform the A1C test at least two times a year in patients meeting treatment goals (and have stable glycemic control) Perform the A1C test quarterly in patients whose therapy has changed or who are not meeting glycemic goals ADA. 6. Glycemic Targets. Diabetes Care 2015;38(suppl 1):S33

19 Approach to the Management of Hyperglycemia ADA. 6. Glycemic Targets. Diabetes Care 2015;38(suppl 1):S37. Figure 6.1; adapted with permission from Inzucchi SE, et al. Diabetes Care, 2015;38:

20 Recommendations: Glycemic Goals in Adults (1) Lowering A1C to below or around 7% has been shown to reduce microvascular complications and, if implemented soon after the diagnosis of diabetes, is associated with long-term reduction in macrovascular disease. Therefore, a reasonable A1C goal for many nonpregnant adults is <7% Providers might reasonably suggest more stringent A1C goals (such as <6.5%) for selected individual patients, if this can be achieved without significant hypoglycemia ADA. 6. Glycemic Targets. Diabetes Care 2015;38(suppl 1):S35

21 Recommendations: Glycemic Goals in Adults (2) Less stringent A1C goals (such as <8%) may be appropriate for patients with History of severe hypoglycemia, limited life expectancy, advanced microvascular or macrovascular complications, extensive comorbid conditions Those with longstanding diabetes in whom the general goal is difficult to attain despite DSME, appropriate glucose monitoring, and effective doses of multiple glucose lowering agents including insulin ADA. 6. Glycemic Targets. Diabetes Care 2015;38(suppl 1):S35

22 APPROACHES TO GLYCEMIC TREATMENT

23 Recommendations: Pharmacological Therapy For Type 1 Diabetes Most people with type 1 diabetes should: Be treated with MDI injections (3 4 injections per day of basal and prandial insulin) or continuous subcutaneous insulin infusion (CSII) A Be educated in how to match prandial insulin dose to carbohydrate intake, premeal blood glucose, and anticipated activity E Use insulin analogs to reduce hypoglycemia risk A ADA. 7. Approaches to Glycemic Treatment. Diabetes Care 2015;38(suppl 1):S41

24 Recommendations: Pharmacological Therapy For Type 2 Diabetes (1) Metformin, if not contraindicated and if tolerated, is the preferred initial pharmacological agent for type 2 diabetes A ADA. 7. Approaches to Glycemic Treatment. Diabetes Care 2015;38(suppl 1):S42

25 Recommendations: Therapy for Type 2 Diabetes (2) A patient-centered approach should be used to guide choice of pharmacological agents Considerations include efficacy, cost, potential side effects, effects on weight, comorbidities, hypoglycemia risk, and patient preferences E Due to the progressive nature of type 2 diabetes, insulin therapy is eventually indicated for many patients with type 2 diabetes B Overall each class of noninsulin agent decreases A1c by % ADA. 7.

40 CARDIOVASCULAR DISEASE AND RISK MANAGEMENT

41 Cardiovascular Disease CVD is the major cause of morbidity, mortality for those with diabetes Largest contributor to direct/indirect costs Common conditions coexisting with type 2 diabetes (e.g., hypertension, dyslipidemia) are clear risk factors for CVD Diabetes itself confers independent risk Benefits observed when individual cardiovascular risk factors are controlled to prevent/slow CVD in people with diabetes ADA. 8. Cardiovascular Disease and Risk Management. Diabetes Care 2015;38(suppl 1):S49

42 Recommendations: Hypertension/Blood Pressure Control Goals People with diabetes and hypertension should be treated to a systolic blood pressure goal of <140 mmhg A Lower systolic targets, such as <130 mmhg, may be appropriate for certain individuals, such as younger patients, if it can be achieved without undue treatment burden C Patients with diabetes should be treated to a diastolic blood pressure <90 mmhg A Lower diastolic targets, such as <80 mmhg, may be appropriate for certain individuals, such as younger patients, if it can be achieved without undue treatment burden B ADA. 8. Cardiovascular Disease and Risk Management. Diabetes Care 2015;38(suppl 1):S49

43 Recommendations: Hypertension/Blood Pressure Control Treatment Pharmacological therapy for patients with diabetes and hypertension comprise a regimen that includes either an ACE inhibitor or angiotensin II receptor blocker B; if one class is not tolerated, substitute the other C An ACE inhibitor or ARB is not recommended for the primary prevention of diabetic kidney disease in patients who have normal blood pressure and a normal urine-albumin-tocreatinine ratio (UACR) (<30 mg/g) B ADA. 8. Cardiovascular Disease and Risk Management. Diabetes Care 2015;38(suppl 1):S50

44 Recommendations: Dyslipidemia/Lipid Management Screening In adults, a screening lipid profile is reasonable E At first diagnosis At the initial medical evaluation And/or at age 40 years and periodically (e.g., every 1-2 years) thereafter ADA. 8.
