Improving HIV and HCV Testing in Substance Use Disorder Programs (SUDs) That Provide Medications for Opiate Use Disorder (MOUD): Role of Addressing Barriers and Implementing Universal and Site-Specific Approaches

Introduction. National strategies to end the HIV epidemic and eliminate hepatitis c (HCV) through a syndemic approach require improvements in testing for HIV and HCV. Given the intersection of the opioid crisis with HIV and HCV acquisition, substance use disorder (SUD) treatment centers providing medications for opiate use disorder (MOUD) provide a critical opportunity to expand testing. Rates of testing in MOUD clinics have been suboptimal. Method. We employed the Nominal Group Technique (NGT), Ishikawa cause and effect diagrams, and individualized Quality Improvement (QI) efforts at two SUD clinics (SUD A and B) in Connecticut (CT) as part of an HRSA-funded grant focused on improving HCV cure in persons with HIV/HCV coinfection. Baseline and longitudinal data were collected on rates of HIV and HCV testing and positivity as well as linkage to treatment. Results. Between April 1, 2019, and May 31, 2021, for SUD A and B respectively, HIV testing increased from 13% to 90% and 33% to 83%; HCV testing increased from 4% to 90% and 30% to 82%, with few reported cases of HIV/HCV coinfection. HCV testing revealed new and prior diagnoses at both sites, with subsequent referrals for treatment. Qualitative assessments identified best practices which included the institution of formal policies and procedures, streamlining of testing logistics, designation of a site champion, and broadening relevant education to staff and clients. Conclusion. Strategic assessment of barriers and facilitators to HIV and HCV testing at MOUD clinics can lead to improved testing and referral rates that are key to improving the cascade of care for both diseases.
