Using the COM-B Model and Theoretical Domains Framework to Examine Intention to Discuss Deprescribing among Complex Older Adults with Diabetes
Abstract
Overtreatment of diabetes in complex older adults (i.e., at least 3 coexisting conditions, at least 2 functional impairments, or cognitive impairment) causes harm. Achieving an A1C < 7.5% in complex older adults with diabetes (COADs) is overtreatment, which can be addressed through deprescribing. Our research will (1) examine the association between patient-related factors and willingness to deprescribe among COADs, (2) determine the predictors of intention to discuss deprescribing with clinicians across patient activation levels, and (3) identify the barriers and facilitators to discuss deprescribing with clinicians. We will analyze data from the National Health and Aging Trends Study and conduct a mixed-methods study with cross-sectional surveys and semi-structured interviews. We expect to understand the underlying mechanism of having the intention to discuss deprescribing with clinicians. This knowledge will support developing interventions to maximize deprescribing opportunities.

It is a great honor to receive the PhRMA Foundation - Predoctoral Fellowship in Value Assessment and Health Outcomes Research award. This award not only recognizes my research efforts, but also emphasizes the significance of a patient-centered approach to deprescribing.
