Managing patients with type 2 diabetes takes time. Clinicians in primary care, where most diabetes visits take place, lack that time. Planned visits by diabetes care managers-nurses, pharmacists, social workers, and other team members-assist clinicians and are associated with improved glycemic control. Particularly effective is care management featuring nurses or pharmacists adjusting medications without prior physician approval. Care management programs need to pay close attention to inequities in diabetes care and outcomes. The widespread implementation of diabetes care management in primary care faces several barriers: lack of an adequate, diverse, trained care manager workforce; regulations limiting care managers' scope of practice; and financial models not supportive of care management. Wide-ranging policies are needed to address these barriers. In particular, payment reform is needed to stimulate the spread of diabetes care management: adding fee-for-service codes that adequately pay care managers for their work, adopting shared savings models that channel savings back to primary care, and increasing the percentage of health care spending dedicated to primary care. In this article we explore key questions around type 2 diabetes care management, review the published evidence, examine the barriers to its wider use, and describe policy solutions.
