Diabetes is a chronic illness that requires continuing medical care and patient self-management education to prevent acute complications and to reduce the risk of long-term complications. Diabetes care is complex and requires that many issues, beyond glycemic control, be addressed. A large body of evidence exists that supports a range of interventions to improve diabetes outcomes. These standards of care are intended to provide clinicians, patients, researchers, payors, and other interested individuals with the components of diabetes care, treatment goals, and tools to evaluate the quality of care. While individual preferences, comorbidities, and other patient factors may require modification of goals, targets that are desirable for most patients with diabetes are provided. These standards are not intended to preclude more extensive evaluation and management of the patient by other specialists as needed. For more detailed information, refer to refs. 1–3. The recommendations included are screening, diagnostic, and therapeutic actions that are known or believed to favorably affect health outcomes of patients with diabetes. A grading system (Table 1), developed by the American Diabetes Association (ADA) and modeled after existing methods, was utilized to clarify and codify the evidence that forms the basis for the recommendations. The level of evidence that supports each recommendation is listed after each recommendation using the letters A, B, C, or E.
A. Classification In 1997, ADA issued new diagnostic and classification criteria (4); in 2003, modifications were made regarding the diagnosis of impaired fasting glucose (5). The classification of diabetes includes four clinical classes:
Recommendations C. Diagnosis of pre-diabetes
Recommendations A. Testing for pre-diabetes and type 2 diabetes in adults B. Testing for type 2 diabetes in children C. Screening for type 1 diabetes
Recommendations
Recommendations
A. Initial evaluation B. Management C. Glycemic control 1. Assessment of glycemic control. a. Self-monitoring of blood glucose Recommendations b. A1C Recommendations 2. Glycemic goals Recommendations 3. Approach to treatment a. Therapy for type 1 diabetes. b. Therapy for type 2 diabetes. D. Medical Nutrition Therapy (MNT) General recommendations Energy balance, overweight, and obesity Primary prevention of diabetes Dietary fat intake in diabetes management Carbohydrate intake in diabetes management Other nutrition recommendations Reimbursement for MNT E. DSME Recommendations Evidence for the benefits of DSME The National Standards for DSME Reimbursement for DSME F.
