Improving diabetes care with patient decision aids: A randomized controlled trial in community-based primary care

This project will conduct a 2-group randomized controlled trial of a patient decision aid (PtDA) focused on diabetes care in community-based primary care practices that serve an ethnically diverse economically disadvantaged patient population. Prior research has demonstrated that PtDAs help racial and ethnic minority patients recognize that a decision needs to be made and prepare them to talk to their physicians about what matters most to them. This project moves beyond subjective evaluations of PtDAs to evaluate whether these tools can also change health behavior and improve health outcomes. The grantee plans to enroll 200 participants from 4 community-based primary care practices in the Los Angeles area and randomize them to receive a state-of-the-art PtDA (experimental group) or standard printed diabetes education materials (control group). Participants will complete self-report measures at baseline, one week following exposure to the interventions and at one- and six-month follow-up. Biological measures (hemoglobin A1c, lipids, blood pressure) will be collected at baseline and six-month follow-up. Trial data will be analyzed using analysis of variance techniques. In addition to quantitative data, the researchers will also collect qualitative data from a subset of participants using in-depth interviews. The project will produce quantitative and qualitative data that will significantly enhance the understanding of the impact of PtDAs on patients from racial and ethnic minority groups. Data will include the constructs usually assessed in decision aid trials (e.g., decisional conflict and satisfaction) but also go beyond these to examine the impact of PtDAs on changes in health behavior and outcomes, thereby maximizing the relevance of our findings for policy-makers. The findings will be presented at national scientific meetings and will be published in peer-reviewed medical journals.
