Impact of Personalized Mail and Telephone Interventions to Improve Follow-up to Vision Care in Patients with Diabetes: Results from Two Randomized Prospective Trials
The purpose of this project was to evaluate the effectiveness of personalized mail and telephone interventions to improve follow-up to vision care in patients with diabetes. The project was divided in two parts. In the first study, 521 patients with diabetes who were due for a follow-up dilated fundus examination (DFE) were randomly assigned to receive 1) a single-mailed reminder form letter (usual care), or 2) a reminder letter plus an educational brochure, followed by a telephone call to schedule a DFE. In the second study, patients with diabetes were randomly assigned to receive 1) a single-mailed reminder letter (usual care), or 2) a personalized reminder letter plus an educational brochure or, 3) usual reminder letter plus a telephone call to schedule the DFE. Barriers to care utilization were also captured. The primary outcome was completion of a DFE within 3 months of suggested return date (timely appointment). Overall, all intervention groups were similar regarding demographic characteristics with a majority being female and African American. A combination of personalized mail and telephone communications and telephone communications alone were more effective in improving DFE adherence than a strategy based solely on standard mailed reminders. However, including an educational brochure did not enhance the effectiveness of the telephone-based intervention. Most commonly reported barriers to scheduling a DFE included busy schedule and issues with health insurance. In summary, a low cost telephone-based intervention significantly improves DFE adherence in an urban primary eye care setting.
