The quality of care delivered to patients with diabetes has an impact on long-term outcomes. The purpose of this quality improvement project was to examine the effect of a Diabetes Disease Management Program (DDMP) on compliance with recommended process measures of care in primary care practice settings. Certified diabetes nurse educators visited five participating primary care practices biweekly for 1 year providing education to physicians and office staff on standards for diabetes management and to patients regarding self-management. Among 208 participants, 85.5% had >2 HbA1cs, 93.6% had lipid profiles, and 100% had foot examinations. Improvements in HbA1c (9.0% to 7.7%) were observed. Implementation of DDMP effectively promotes compliance with care standards in primary care practices.
