Integrated Care and Treatment for Severe Infectious Diseases and Substance Use Disorders Among Hospitalized Patients

The goal of this clinical trial is to test the effectiveness of an integrated infectious disease/substance use disorder (SUD) clinical team intervention approach in patients hospitalized with severe injection-related infections (SIRI) who use drugs. The main question this study aims to answer is whether this intervention approach will be associated with lower mortality and fewer hospital readmissions. Participants will participate in the integrated SUD/ID care team intervention (SIRI Team). Researchers will compare this intervention to treatment as usual (TUA) to see if there are any differences in health outcomes.
