The study intervention ("SIRI Team") consists of a hospital-based multidisciplinary (ID/SUD consult) team that will provide intensive, integrated care for participants' ID and SUD both during the hospital stay and post-discharge for up to four months post-randomization. The SIRI Team will provide low barrier access to medications and harm reduction services for SUD; streamline ID/SUD treatment; provide longitudinal care with familiar providers; leverage different areas of expertise between physicians, advance practice providers, and patient navigators; and create patient-centered treatment plans, tailored to the individual, and informed by each patient's social circumstances, substance use, and personal goals/desires. The SIRI Team intervention will be grounded in a harm reduction approach. The intervention duration is approximately 4 months. Participants will complete follow-up visits at 4-, 8-, and 12-months post-randomization.
