Background: People living with diabetes are often taking multiple medications for glycemic control. There is an inverse relationship between the complexity of the medication regimen and adherence. Motivational interviewing has been shown to improve medication adherence in chronic disease state management. Objectives: Evaluate the use of motivational interviewing and the impact on medication adherence and hemoglobin A1C (A1C) levels. Methods: This single-center, quality improvement study included adult participants enrolled in a Diabetes Self-Management, Education, and Training program. All patients completed a Morisky Medication Adherence Scale and had A1C and other clinical biomarkers recorded at baseline and each additional encounter. Proportion of days covered (PDC) was calculated for the six months prior to and after study enrollment. Results: The greatest percent reduction in body mass index (-0.5%) and blood pressure (-3.5% average) occurred in subjects attending group classes, while the greatest percentage reduction for A1C occurred in subjects attending individual sessions only (-7.1%). PDC increased in subjects attending group sessions (47.2%, p=.008) and decreased in subjects attending individual sessions only (-32.6%, p=.035). Conclusion: Motivational interviewing, applied in a group setting and in a repeated format, is more impactful on improving medication adherence than individual education or single application alone.
