Case management involves coordinating healthcare services for people with diabetes. The Task Force found strong evidence that diabetes case management improves glycemic control. Case management includes appointing a case manager to oversee services, assessing needs, developing care plans, implementing plans, and monitoring results. A review of 15 studies found case management reduced average HbA1c levels by 0.53% when combined with disease management and 0.40% without it. However, the evidence was insufficient to determine the effectiveness on other health outcomes.
