# P-346. Implementation of an Inpatient HIV Antiretroviral Transitions of Care Pilot at a Veterans Affairs (VA) Medical Center

## TL;DR

A pharmacist-led program at a VA hospital improved HIV care during hospital admissions by optimizing antiretroviral therapy and linking patients to follow-up care.

## Contribution

A feasible, pharmacist-led inpatient HIV transitions of care program was implemented and shown to improve medication safety and care linkage.

## Key findings

- 73% of ART reviews resulted in at least one intervention, with 120 total interventions made during the 8-month pilot.
- Outpatient ID clinic follow-up was arranged for 38 patients, with 20 attending follow-up appointments, including 3 previously out of care.
- Routine HIV lab monitoring recommendations were made in 35 cases, showing improved medication safety and care coordination.

## Abstract

During transitions of care (TOC), people living with HIV (PLWH) often warrant additional attention beyond a routine medication reconciliation. In August 2024, a single center pharmacist-led quality improvement pilot program was begun to enhance the care of this high-risk population during new hospital admissions. An aim of this pilot program was to assess the impact of inpatient HIV TOC on HIV treatment and linkage to care.

Between August 1st, 2024, and March 31st, 2025, electronic medical record (EMR) alerts for inpatient antiretroviral therapy (ART) orders were reviewed Monday through Friday by the Infectious Diseases (ID) pharmacist. Patients were only reviewed once per admission and were excluded if a formal ID consult had been placed. The ART review included HIV treatment history, medication interactions, and established linkage to HIV care if needed. These findings were documented as an HIV pharmacotherapy note in the EMR. Interventions were made by the ID clinical pharmacist and/or in collaboration with an ID physician or the inpatient medical team.

During the 8-month pilot period, there were 92 ART reviews (70 unique patients) of which 67 resulted in at least 1 intervention (73%). There were 120 total interventions made. Routine HIV laboratory monitoring recommendations were made to primary teams in 35 cases. ART interventions were made in 39 cases including: addressing drug-drug interactions (15), dose adjustment (5), ART refills (17), and ART changes (2). Outpatient ID clinic follow up was arranged in 44 cases for 38 unique patients. Of these, 20 subsequently attended a follow up appointment including 3 patients who had previously been out of care.

HIV ART monitoring at transitions of care resulted in tangible benefits such as improved medication safety and linkage to care for PLWH at our medical center. A simple EMR alert resulted in a specialty pharmacist review that was shown to be feasible and resulted in multiple episodes of ART optimization and improved patient care. This inpatient program will continue at our medical center and is expected to lead to improvements in health outcomes.
