Reducing Hospital Readmissions for Injection Drug Use-Related Infections: A Rapid Qualitative Analysis of Health Care Teams’ Consultations to Inform Intervention Design

Le résumé fourni par la source

OBJECTIVES: People who inject drugs (PWID) face elevated risks of hospitalizations and readmissions due to serious injection-related infections, yet few evidence-based interventions exist to prevent readmissions. This study aimed to explore factors contributing to rehospitalization among PWID, potential strategies, and assess the acceptability of 2 proposed interventions and implementation considerations. METHODS: We conducted 22 semistructured interviews with 36 health care providers and staff across 4 study sites in Georgia, Maryland, the District of Columbia, and West Virginia from June 2023 to September 2023. Participants were purposively sampled to represent diverse roles in providing or overseeing care to PWID. Interviews explored barriers to care, challenges contributing to rehospitalization, and perceptions of 2 proposed interventions: (1) integrated care for addiction and infectious diseases, and (2) patient navigation to support linkage to care postdischarge. Data were analyzed using rapid qualitative analysis informed by framework and thematic approaches. RESULTS: Three main themes emerged regarding rehospitalization factors (unaddressed structural, health system, and social determinants; gaps in addiction care training; and continuity of care). Participants expressed high acceptability toward the proposed interventions. Three main themes emerged as recommendations for the implementation of the proposed interventions (organizational needs and capacity; leveraging existing resources; patient engagement and retention). CONCLUSIONS: Reducing readmissions among PWID requires addressing provider training gaps, care fragmentation, and structural barriers. Both proposed interventions were deemed acceptable by health care team members. Key implementation factors include strengthening organizational capacity, leveraging existing resources effectively, and using person-centered approaches to build trust and maintain patient engagement and retention.
