The American Diabetes Association (ADA) "Standards of Medical Care in Diabetes" includes ADA's current clinical practice recommendations and is intended to provide the components of diabetes care, general treatment goals and guidelines, and tools to evaluate quality of care. Members of the ADA Professional Practice Committee, a multidisciplinary expert committee, are responsible for updating the Standards of Care annually, or more frequently as warranted. For a detailed description of ADA standards, statements, and reports, as well as the evidence-grading system for ADA's clinical practice recommendations, please refer to the Standards of Care Introduction. Readers who wish to comment on the Standards of Care are invited to do so at professional.diabetes.org/SOC. In the hospital, both hyperglycemia and hypoglycemia are associated with adverse outcomes, including death (1,2). Therefore, inpatient goals should include the prevention of both hyperglycemia and hypoglycemia. Hospitals should promote the shortest safe hospital stay and provide an effective transition out of the hospital that prevents acute complications and readmission. For in-depth review of inpatient hospital practice, consult recent reviews that focus on hospital care for diabetes (3,4). HOSPITAL CARE DELIVERY STANDARDS Recommendation 15.1 Perform an A1C on all patients with diabetes or hyperglycemia (blood glucose .140 mg/dL [7.8 mmol/L]) admitted to the hospital if not performed in the prior 3 months. B High-quality hospital care for diabetes requires both hospital care delivery standards, often assured by structured order sets, and quality assurance standards for process improvement. "Best practice" protocols, reviews, and guidelines (2) are inconsistently implemented within hospitals. To correct this, hospitals have established protocols for structured patient care and structured order sets, which include computerized physician order entry (CPOE). Considerations on Admission Initial orders should state the type of diabetes (i.e., type 1 or type 2 diabetes) or no previous history of diabetes. Because inpatient insulin use (5) and discharge orders (6) can be more effective if based on an A1C level on admission (7), perform an A1C test on all patients with diabetes or hyperglycemia admitted to the hospital if the test has not been performed in the prior 3 months (8). In addition, diabetes self-management knowledge and behaviors should be assessed on admission and
