Barriers and facilitators to implementing treatment for opioid use disorder in community hospitals

Introduction

Methadone and buprenorphine are effective treatment for opioid use disorder (OUD), yet they are vastly under-utilized across US hospitals. To inform a national trial assessing the effectiveness of implementation strategies to increase adoption of an inpatient hospital-based opioid treatment (HBOT) model (NCT04921787), we explored barriers and facilitators to expanding medication for opioid use disorder (MOUD) within community hospitals across the United States.

Methods

From November 2021 to March 2022, we used purposeful and snowball sampling to identify and interview participants involved in inpatient care of patients with OUD from twelve community hospitals. We conducted semi-structured interviews on providers' experiences and perspectives on current treatment approaches as well as potential influences on MOUD expansion in their hospitals. We used thematic analysis to identify key barriers and facilitators that could impact implementation of an HBOT model, and organized these findings based on the Consolidated Framework for Implementation Research (CFIR).

Results

From qualitative interviews with 57 participants (30 physicians, 7 pharmacists, 6 nurses, and 14 professionals involved in the care of patients with OUD), we identified key barriers and facilitators mapped to CFIR's internal and outer settings. The most salient inner setting domains included tension for change and relative priority, compatibility, available resources, organizational culture, access to knowledge and information, relational connections and communications, and information technology infrastructure. Outer setting domains included policies and laws, financing, and partnerships and connections.

Conclusions

Identifying potential barriers and facilitators can inform hospital-specific strategies to support implementation of HBOT. Implementation strategies that address barriers such as staff availability, knowledge, and attitudes may support increased HBOT adoption. On a broader scale, national policy changes such as increased financing and public reporting of quality metrics would address other barriers we identified and may also encourage hospitals to adopt HBOT models.
