This document discusses how addressing social determinants of health, like housing conditions, could improve patient care and lower costs. It provides the example of Mrs. M, who had chronic headaches and multiple ER visits without diagnosis. Only after a clinic screened for housing risks did they discover she lived in a damp, moldy home, correctly diagnose her issue, and treat her condition along with improving her housing. The document argues that routinely asking patients about living conditions could help doctors better diagnose and treat patients. It also discusses how Medicaid Health Home programs and 1115 waivers could allow states to use Medicaid funding to address social needs like housing that impact health outcomes.
