Two studies—one in New York City and the other in San Francisco—examined the experiences of formerly homeless persons who entered housing programs. Carole E. Siegel, Ph.D., and her colleagues used statistical modeling techniques and propensity scoring to closely examine outcomes over 18 months for 157 persons entering either supported housing or more service-intensive community residences. Tenure in housing did not differ by housing type. Many in supported housing whose clinical profiles suggested more appropriate placement in community residences were successfully housed (page 982). In San Francisco, Tia E. Martinez, J.D., and Martha R. Burt, Ph.D., examined use of acute health care services among 236 formerly homeless individuals with dual diagnoses for two years after they entered a "low demand" housing program, which did not require treatment participation or abstinence. Providing permanent supportive housing to this group significantly reduced their use of emergency department and inpatient services (page 992). In both studies, substantial proportions of participants remained housed.
