Early Outcomes of Mental Health Screening Integrated Into Routine HIV Care in Malawi.

Abstract

Mental health (MH) disorders are highly prevalent among people living with HIV and can have a negative impact on antiretroviral therapy (ART) outcomes. Malawi's Ministry of Health introduced MH screening in national HIV management guidelines in 2022. We describe early experience with integrated MH screening at ART clinics that have scarce human resources and limited capacity of specialist MH units. ART staff in 15 facilities were trained to use the Patient Health Questionnaire-9 (depression) and the Alcohol Use Disorders Identification Test (harmful alcohol use) screening instruments, MH registers were developed for tracking screening results and referrals, and existing MH referral units were engaged. Based on screening results, ART clients received counseling by lay cadre staff (for mild symptoms) or intensive counseling by trained psychosocial counselors and referrals to specialist MH units (for moderate to severe symptoms). From October 2022 through July 2023, 9,826 ART clients were screened from the following priority groups: returning to care after an interruption in treatment (50%), newly diagnosed (38%), and viral load ≥1,000 copies/mL (12%). Of those screened, 59% were female and 14% were aged 12-19 years. Screening coverage was 85% (9,826/11,553) among the 3 priority groups. All of the individuals who screened positive for moderate/severe depression (1.1%; n=106) or high risk for harmful alcohol use (2.3%; n=227) were referred to specialist MH units. In conclusion, thorough preparation led to high MH screening coverage among ART priority groups, and the number of referrals to specialist MH units was low. MH screening was feasible at Malawi ART clinics. Next steps include studying the clinical impact of integrated MH screening on MH outcomes and ART outcomes (retention in care and viral suppression) and scaling up integrated MH screening to all ART clinics.
