Primary care providers (PCPs) are responsible for the medical management of patients with chronic illness. Unfortunately, many PCPs do not adhere to national guidelines. This quality improvement (QI) project was designed to use the Awareness-to-Adherence theory to strengthen the PCPs understanding of the American Diabetes Association (ADA) guideline for the testing frequency of Glycosylated Hemoglobin A1c (A1c) in patients with diabetes mellitus Type 2 (DM2). Before implementation of the project, PCPs ordered the A1c per ADA guideline on 37% of their patients with DM2. After the QI project the PCPs ordered the A1c per ADA guidelines on 65% of patients with DM2; a net gain of 28%.
