The YDC’s Inpatient Diabetes Management Team, founded in 2005, is the only one of its kind in Connecticut. The team focuses on improving the blood glucose control of patients hospitalized at Yale-New Haven Hospital with high blood sugar. 

Team members consist of nurse practitioner Linda Ferro, as well as Anne Kaisen, Leigh Bak, and Karen McAvoy, who serve as Yale-New Haven Hospital's Clinical Diabetes Nurse Specialists; endocrine fellows; and an attending endocrinologist. Rounds are conducted daily. 

Yale is a national leader in the development of protocols and procedures to ensure optimal glucose control during hospitalizations. The Yale Insulin Infusion Protocol, for example, is now used by hundreds of hospitals around the world to achieve meticulous glucose control in critical care units.

Clinical research opportunities are also available for our patients, who may take advantage of ongoing clinical trials at the NIH-funded Yale Center for Clinical Investigation (YCCI).
