Abstract
BACKGROUND: Driven by increased injection opioid use, rates of hospitalisation for infective endocarditis, an infection associated with injection drug use, are increasing. In the USA, 1 in 10 hospitalised patients for opioid use disorder-associated infective endocarditis (OUD-IE) die in the hospital and 1 in 20 have a patient-directed discharge. Emerging models of care reveal opportunities for healthcare systems to meet the complex care needs of these patients. We characterised promising practices of staff who care for these patients and identified areas for improvement. METHODS: We conducted a qualitative study with 1-hour semistructured virtual interviews between October 2021 and March 2022. Participants included 26 healthcare staff who care for patients with OUD-IE at the Hospital of the University of Pennsylvania. We used thematic analysis of interviews guided by an abductive approach. Interviews were digitally recorded and transcribed and analysed using NVivo software. RESULTS: Interviews were characterised by three major themes: (1) care rooted in interdisciplinary collaboration; (2) managing OUD and its sequelae in a setting not designed to treat OUD; and (3) clinician needs and barriers to change. CONCLUSIONS: These findings highlight the facilitators of high-quality treatment for patients with OUD-IE, as well as the key areas for improvement. Findings add context to the complexity that both the healthcare staff and patients navigate during and following hospitalisation for OUD-IE. Needed changes include training staff to talk with patients about preparing for a return to drug use following hospitalisation, and changing discharge facilities' practices that hinder access for patients with OUD-IE.
