The Project seeks to reduce new HIV infections while addressing SUD and mental health issues that patients exhibit. BACH will increase access to care and promote health equity for 300 patients per year for the grant period. BACH will refer these 300 high-need, medically underserved clients in southern Alameda County and SCC to SUD services, of whom 75 will be referred to BACH’s Medically Assisted Treatment (MAT) Program. BACH will expand current and establish new services, which will increase HIV testing, resultant referrals and access to SUD services, naloxone, fentanyl detection kits, PrEP and nPEP, link persons with HIV to HIV medical care and antiretroviral therapy (ART) and provide and/or refer previously diagnosed or those at risk of HIV to HIV and SUD prevention and treatment, including mental health services. The Project seeks to reduce the impact of SUD and HIV infection and death rate, and HIV-related disparities while improving health outcomes despite HIV status. The Project will thus implement outreach and promotion in SCC and Alameda County that supports those with or at risk of HIV to access HIV testing, during which, staff will conduct client-centered, trauma-informed screenings for medical and non-medical risk factors and social determinants of health (SDOH), including SUD and mental health issues.
