Primary outcomePrimary: Number of Participants With Diabetes Care Gaps at Baseline, 3 Months, 6 Months, and 12 Months — 75; 57; 77; 79 Participants — p=<0.001
Summary
The purpose of this study is to evaluate the effect of a novel patient portal intervention on the number of patients with diabetes care gaps (e.g., no diabetes eye exam i the last 12 months). The intervention is designed to: (a) notify patients when selected, clinically meaningful, evidence-based diabetes monitoring & preventative care (e.g., annual urine microalbumin) are due and (b) allow patients to initiate orders for the care.
