Abstract OBJECTIVE: To evaluate an online disease management system supporting patients with uncontrolled type 2 diabetes. MATERIALS AND METHODS: Engaging and Motivating Patients Online With Enhanced Resources for Diabetes was a 12-month parallel randomized controlled trial of 415 patients with type 2 diabetes with baseline glycosylated hemoglobin (A1C) values ≥7.5\% from primary care sites sharing an electronic health record. The intervention included: (1) wirelessly uploaded home glucometer readings with graphical feedback; (2) comprehensive patient-specific diabetes summary status report; (3) nutrition and exercise logs; (4) insulin record; (5) online messaging with the patient's health team; (6) nurse care manager and dietitian providing advice and medication management; and (7) personalized text and video educational 'nuggets' dispensed electronically by the care team. A1C was the primary outcome variable. RESULTS: Compared with usual care (UC, n=189), patients in the intervention (INT, n=193) group had significantly reduced A1C at 6 months (-1.32\% INT vs -0.66\% UC; p<0.001). At 12 months, the differences were not significant (-1.14\% INT vs -0.95\% UC; p=0.133). In post hoc analysis, significantly more INT patients had improved diabetes control (>0.5\% reduction in A1C) than UC patients at 12 months (69.9 (95\% CI 63.2 to 76.5) vs 55.4 (95\% CI 48.4 to 62.5); p=0.006). CONCLUSIONS: A nurse-led, multidisciplinary health team can manage a population of diabetic patients in an online disease management program. INT patients achieved greater decreases in A1C at 6 months than UC patients, but the differences were not sustained at 12 months. More INT than UC patients achieved improvement in A1C (>0.5\% decrease). Trial registered in clinical trials.gov: #NCT00542204.
