Urban Health Activities

Community Health Advisory & Information Network (CHAIN): Dr. Messeri was the principal investigator of CHAIN, a longitudinal study of persons living with HIV/AIDS. Since his retirement he has continued as a senior investigator. Since its inception in 1994, CHAIN has followed over 2,400 people living with HIV in the New York City region. The goal of CHAIN is to assess the need for health and social services among people living with HIV/AIDS and to understand the availability, accessibility, and quality of HIV/AIDS services. Based on repeated in-person interviews with study participants, the study informs the planning of HIV services in New York City through the production of reports on data collected written in collaboration with New York City Department of Health and Mental Hygiene, Public Health Solutions, and the Westchester Department of Health. The study is primarily funded through the Ryan White CARE Act, with supplemental funding from the federal government and various private foundations.

Evaluation of HomeBase Program to Prevent Family Homelessness: This study evaluated NYC Department of Homelessness Services' innovative community-based homelessness prevention program, HomeBase. With Dan O'Flaherty, CU Department of Economics, Dr. Messeri undertook a quasi-experiment using administrative dataset to demonstrate that the program was effective in averting family entries into the New York City Shelter System.

Access NY and AmidaCONNECT: These related projects evaluated innovative programs to improve connection and retention in care among New York City residents living with HIV/AIDS, who experience difficulty in maintaining engagement with medical care. The project was a collaboration with Amida Care, an HIV medicaid managed care plan, serving New York City residents and the New York Community Trust. The project was supported by funds from the AIDS Fund, AIDS United, and the Corporation for National and Community Service.
