The Housing and Health study examines the effects of permanent supportive housing for homeless and unstably housed persons living with HIV. While promising as an HIV prevention intervention, providing housing may be more expensive to deliver than some other HIV prevention services. Economic evaluation is needed to determine if investment in permanent supportive housing would be cost-saving or cost-effective. Here we ask -- what is the per client cost of delivering the intervention, and how many HIV transmissions have to be averted in order to exceed the threshold needed to claim cost-savings or cost-effectiveness to society? Standard methods of cost and threshold analysis were employed...

Homelessness and unstable housing have been associated with HIV risk behavior and poorer health among persons living with HIV/AIDS (PLWHA), yet prior research has not tested causal associations. This paper describes the challenges, methods, and baseline sample of the Housing and Health Study, a longitudinal, multi-site, randomized controlled trial investigating the effects of providing immediate rental housing assistance to PLWHA who were homeless or at severe risk of homelessness. Primary outcomes included HIV disease progression, medical care access and utilization, treatment adherence, mental and physical health, and risks of transmitting HIV...

This study examines patterns of sexual behavior, sexual relating, and sexual risk among HIV-positive men sexually active with women. A total of 278 HIV-positive men were interviewed every 6-12 months between 1994 and 2002 and reported considerable variability in sexual behaviors over time. Many were not sexually active at all for months at a time; many continued to have multiple female and at times male partners. Over one-third of the cohort had one or more periods when they had engaged in unprotected sex with a female partner who was HIV-negative or status unknown (unsafe sex)...

As an ever-increasing number of people infected with HIV are living longer, healthier lives, concerns about continued transmission are growing along with an awareness of the need to develop "prevention for positives." This study of HIV-positive adults in New York City is the first examination of patterns of sexual behavior in a large, representative cohort of HIV-infected individuals followed over an extended time period. A total of 968 HIV-positive adults were interviewed every 6-12 months between 1994 and 2002 and reported considerable variability in sexual behaviors over time...

This paper examines housing as a contextual factor affecting drug and sexual risk behaviors among HIV positive people using pooled interview data from 2149 clients presenting for services at 16 medical and social service agencies participating in a multi-site evaluation study. The odds of recent drug use, needle use or sex exchange at the baseline interview was 2-4 times as high among the homeless and unstably housed compared to persons with stable housing. Follow-up data collected 6-9 months after baseline showed that change in housing status was associated with change in risk behaviors...

Home telehealth involves the use of video conferencing or remote monitoring equipment in patients' homes. The installation of hardware and training of patients has historically been performed by nurses, typically RNs. This article examines the experience of RNs as telehealth installers in the Informatics for Diabetes Education and Telemedicine (IDEATel) project, where RNs were responsible for the installation of the Home Telemedicine Units (HTUs) and for training patients in the use of the HTUs, blood pressure cuffs, and fingerstick glucose meters...

OBJECTIVE: This study estimates the impact of Highly Active Antiretroviral Therapy (HAART) and other antiretroviral therapy combinations on reducing mortality risk for a cohort of HIV-infected persons living in New York City. MATERIALS AND METHODS: Data for this study come from the CHAIN project, an ongoing multiwave longitudinal study of HIV-infected persons is living in New York City (n = 700) initiated in 1994. The study sample is drawn from the clients of 43 medical and social service agencies and is broadly representative of New York City residents, who were aware of their positive serostatus at time of enrollment...
