The Housing and Health study examined 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 other HIV prevention services. To understand the economic feasibility of the approach, this study examines the per client cost of the intervention, as well as the number of HIV transmissions that must be averted to claim cost-savings or cost-effectiveness for society. The study found that if just one out of every 19 Housing & Health intervention clients avoided HIV transmission to an HIV seronegative partner, the intervention would be cost-saving, and the intervention would be cost-effective if it prevented just one HIV transmission for every 64 clients served.
