The Los Angeles Commission on HIV (COH), in conjunction with the Department of Public Health Office of AIDS Programs and Policy (OAPP) and the Prevention Planning Committee (PPC), developed the Los Angeles County HIV Needs Assessment (LACHNA). This comprehensive survey combined the PPC’s annual prevention survey with the COH’s assessment of service needs and gaps of persons living with HIV/AIDS. Key survey domains included: demographic information, benefit services, Medicare Part D, living situation, substance, psychological symptoms/complaints, medical care, medication adherence, oral health care, unmet need. The project was to conduct an analysis of the LACHNA data for the purpose of planning of HIV/AIDS care and treatment services in Los Angeles, CA.
