Improving Participation in HIV Preexposure Prophylaxis via an Informatics Approach—a Process-Improvement Project

With this project, we aimed to re-engage military health care beneficiaries with expired HIV preexposure prophylaxis prescriptions at Madigan Army Medical Center (Tacoma, WA). We identified prescriptions expired between August 2022 and August 2023 via electronic health records, then called patients to assess HIV risk and arrange follow-up. Of those with clinical indications, 80% agreed to re-engage with preexposure prophylaxis services, increasing the number of patients receiving preexposure prophylaxis at our institution by 30%. Systematic electronic health records query can reduce nonadherence when active case management is not feasible.
