RecruitingClinical trialHepatitis C Pharmacist, Physician, Patient Navigator Collaborative Care Model in Permanent Supportive HousingThe objective of this study is to extend our prior research by conducting a pragmatic implementation trial using a parallel-group, cluster randomized design to evaluate the PPP-CCM's ability to improve access to DAAs for HCV within a network of permanent supportive housing (PSH) buildings in Seattle and King County. The study will implement PPP-CCM to 16 housing buildings, randomizing half to receive PPP-CCM (intervention) versus usual care (UC) for 12-months, after which all buildings will have access to PPP-CCM. All buildings will have access to point-of-care HCV screening for the first 6 months of the study. Study outcome data will be collected through a longitudinal cohort-study of persons who screened positive for HCV which will conduct surveys and review of medical records at baseline, 12- and 24-months.
