Abstract
Increased treatment complexity in patients with diabetes contributes to medication nonadherence. Patient portals that are accessible through electronic health records may offer improved patient-provider communication and better medication management in patients with diabetes and uncontrolled hypertension. We conducted a prospective, mixed-methods evaluation of the Duke PillBox application, a SMART-on-FHIR medication management application integrated into the electronic health record patient portal. Adults with active portal status, diabetes, and uncontrolled hypertension participated in a usability/feasibility survey and communicated with a pharmacist via the portal-based application who conducted medication reconciliation and discussed medication indications, side effects, and barriers to use with patients. Of the eligible patients (n = 285), 29 (10%) were interested, and 12 (8%) participated. Challenges to usability were due to the electronic health record-portal communication interface (91%), browser access and compatibility (55%), and persistent lists of unused medications in the electronic health record (27%). The findings of this study suggest that electronic health record-integrated medication applications are desirable as indicated in patient interactions at the outset and conclusion of the study. Persistent challenges included electronic health record integration, interoperability, user interface, and browser connectivity for both patients and providers.
