Estimated program impacts^† on one-year Medicaid costs post supportive housing using optimal full matching versus one-to-one greedy matching.

Abbreviations: NE, non-estimable; SUD, substance use disorder.

These estimates were based on Hodges-Lehmann (full matching) and Wilcoxon (one-to-one matching) signed rank test (two-sided p-value).

Some estimates were non-estimable because a majority of subjects had zero outcomes.

Because there were more placed subjects than unplaced ones, each random selection of placed subjects prior to matching produced slightly different matched pairs, which resulted in slightly different estimates.

Data sources: NYC Department of Homeless Services, NYC Department of Correction, NYC Department of Health and Mental Hygiene, NYC Human Resources Administration and within it Customized Assistance Services and the HIV/AIDS Services Administration, and New York State Office of Mental Health.
