Implementation of a bundle to improve HIV testing during hospitalization for people who inject drugs.

Background: Increased HIV testing is essential to ending the HIV epidemic. People who inject drugs (PWID) are among the highest risk for HIV infection. Previous research at Tufts Medical Center identified low HIV testing rates in hospitalized PWID. Our research team aimed to identify and overcome barriers to inpatient HIV screening of PWID using implementation science methods.

Methods: Stakeholders were engaged to gather perspectives on barriers and facilitators of HIV testing. A PWID care bundle was developed and implemented, which included (1) HIV screening; (2) hepatitis A, B, and C testing and vaccination; (3) medications for opioid use disorder; and (4) naloxone prescription. Strategies from all nine Expert Recommendations for Implementing Change (ERIC) clusters guided the implementation plan. Stakeholder feedback was gathered throughout implementation, and implementation outcomes of acceptability and feasibility were assessed.

Results: PWID overall felt comfortable with HIV testing being offered while hospitalized. Clinicians cited that the main barriers to HIV testing were discomfort and confusion around consenting requirements. Many resident physicians surveyed reported that, at times, they forgot HIV testing for PWID. Overall, though, resident physicians felt that the PWID bundle was useful and did not distract from other patient care responsibilities.

Conclusions: Engagement of key stakeholders to increase HIV testing in an inpatient setting led to the implementation of a PWID bundle, which was feasible and acceptable. Bundling evidence-informed care elements for inpatient PWID should be investigated further.
