Center for Outcomes Research & Education (CORE), 2014
This report investigates the health and cost outcomes associated with a supportive housing residence in Portland, Oregon. It finds that tenants on Medicaid at Bud Clark Commons (BCC) averaged roughly $2,000 per month in healthcare costs in their year prior to housing. Once housed, that figure dropped to just $899 a month, a 55% decrease. Collectively, the 59 tenants studied at BCC reduced their Medicaid costs by more than $783,000 in just one year. This reduction in Medicaid claims is greater than the estimated annual cost of the housing for these tenants. The report also finds that savings increase as the years go on, which suggests that "supportive housing had a profound and ongoing impact on health care costs for those living at BCC."
