Change in glycemic control for patients enrolled in a membership-based primary care program: Longitudinal observational study

Abstract

Background: Both primary care practices based on the chronic care model (CCM) and digital therapeutics have been shown to improve the care of patients with diabetes. Objective: The aim of this observational study was to examine the change in diabetes control for patients enrolled in a membership-based primary care service that is based on the CCM. Methods: Using a diabetes registry, we analyzed the change in glycated hemoglobin (HbA1c) for patients with uncontrolled diabetes mellitus (initial HbA1c.9%). All patients had access to a technology-enhanced primary care practice built on the CCM. Results: The registry included 621 patients diagnosed with uncontrolled diabetes. All patients had at least two HbA1c measurements, with the average time between the first and last measurement of 1.2 years (SD 0.4). The average starting value of HbA1c was 10.7, which decreased to 8.7, corresponding to a reduction of 2.03 (P
