Influence of Patient Literacy on the Effectiveness of a Primary Care-Based Diabetes Disease Management Program

This study was conducted to examine the role of literacy on the effectiveness of a comprehensive disease management program for patients with diabetes. Data from a randomized controlled trial of a comprehensive diabetes management program were analyzed to explore the influence of literacy on glycemic control and systolic blood pressure.

Key Findings:

  • Among patients with low literacy, intervention patients had more improvement in glycemic control [HbA1c] levels and were more likely than control patients to achieve goal HbA1c levels.
  • Patients with higher literacy had similar odds of achieving goal HbA1c levels regardless of intervention status.
  • Overall, intervention patients improved systolic blood pressure more than control patients, yet differences were comparable for patients with low and higher literacy levels.
