Abstract
INTRODUCTION: The Education-Centered Medical Home (ECMH) is a longitudinal clerkship that emphasizes continuity and quality improvement in primary care. We aimed to evaluate our ECMH's ability to improve type 2 diabetes mellitus (T2DM) care through a systematic chart audit and care planning process. The effect of this intervention was measured by adherence to process and outcome measures. METHODS: From November 2015 to March 2017, medical students were educated on and performed monthly chart audits of guideline-based quality metrics: hemoglobin A1c systolic blood pressure; lipid and microalbuminuria evaluation; annual ophthalmic and foot examinations; flu, hepatitis, and pneumonia vaccination; and statin therapy. Patients were included if they had a diagnosis of T2DM and were seen by the ECMH clinic before and after the audits started. Students shared audit logs, using them to plan patient appointments. We assessed changes in proportion of patients meeting each guideline with Fisher's exact test. RESULTS: The project included 11 patients with T2DM. ECMH adherence to the annual eye exam increased significantly 1 year postintervention, compared to preintervention (73% vs 55%; P=.03) and 6 months (73% vs 46%, P=.01). CONCLUSION: The metric with significant improvement during the chart audit, annual eye exam, is a process measure requiring advance planning. This small study suggests that a formal, regular audit process can improve student adherence to evidence-based care guidelines, particularly for tasks that require advance planning or action by the care team outside the day of a patient visit.
