TY - JOUR T1 - HEalth care and public service use and costs before and after provision of housing for chronically homeless persons with severe alcohol problems AU - Larimer ME, Malone DK, Garner MD, et al Y1 - 2009/04/01 N1 - 10.1001/jama.2009.414 JO - JAMA SP - 1349 EP - 1357 VL - 301 IS - 13 N2 - Context  Chronically homeless individuals with severe alcohol problems often have multiple medical and psychiatric problems and use costly health and criminal justice services at high rates.Objective  To evaluate association of a “Housing First” intervention for chronically homeless individuals with severe alcohol problems with health care use and costs.Design, Setting, and Participants  Quasi-experimental design comparing 95 housed participants (with drinking permitted) with 39 wait-list control participants enrolled between November 2005 and March 2007 in Seattle, Washington.Main Outcome Measures  Use and cost of services (jail bookings, days incarcerated, shelter and sobering center use, hospital-based medical services, publicly funded alcohol and drug detoxification and treatment, emergency medical services, and Medicaid-funded services) for Housing First participants relative to wait-list controls.Results  Housing First participants had total costs of $8 175 922 in the year prior to the study, or median costs of $4066 per person per month (interquartile range [IQR], $2067-$8264). Median monthly costs decreased to $1492 (IQR, $337-$5709) and $958 (IQR, $98-$3200) after 6 and 12 months in housing, respectively. Poisson generalized estimating equation regressions using propensity score adjustments showed total cost rate reduction of 53% for housed participants relative to wait-list controls (rate ratio, 0.47; 95% confidence interval, 0.25-0.88) over the first 6 months. Total cost offsets for Housing First participants relative to controls averaged $2449 per person per month after accounting for housing program costs.Conclusions  In this population of chronically homeless individuals with high service use and costs, a Housing First program was associated with a relative decrease in costs after 6 months. These benefits increased to the extent that participants were retained in housing longer. SN - 0098-7484 M3 - doi: 10.1001/jama.2009.414 UR - http://dx.doi.org/10.1001/jama.2009.414 ER -
