Additional Information

Official title Improving Diabetes Care Collaboratively in the Community
Principal investigator Marshall H Chin, MD, MPH
Description In 1998 the Health Resources and Services Administration's Bureau of Primary Health Care began the Health Disparities Collaborative (HDC) to improve chronic disease management in community health centers (HC) nationwide. The HDC incorporates rapid quality improvement (QI), a chronic care model, and best practices. This study determines if the HDC improves diabetes care and whether more intensive interventions with additional learning sessions for health centers, provider training in behavioral change, and patient empowerment materials enhance care further.
