The primary objective of this proposal is to conduct surveys and qualitative interviews to get feedback from (1) stakeholders and (2) people with lived experience of opioid use and a related medical hospitalization, on the barriers and facilitators of new potential strategy of treatment. The potential proposed intervention we will ask questions about is the direct mailing medications for opioid use disorder (OUD) in an attempt to overcome many of the barriers that interfere with treatment retention (i.e. transportation). Qualitative interviews will be used to get feedback on the feasibility, appropriateness, and acceptability of mailing maintenance medications for OUD after a hospital discharge. In a future study, this feedback will be used to develop a protocol to test this method.
