Research output: Chapter in Book/Report/Conference proceedingChapter


Serious mental illness (SMI) and homelessness each create significant burden on impacted individuals and pose major system- and provider-level challenges. With annual estimates of roughly 11 million individuals suffering from a serious mental illness such as schizophrenia, schizoaffective disorder, or severe bipolar disorder and greater than a half a million people experiencing homeless on a given night in the United States, the magnitude of each issue is sobering. Additionally, individuals with serious mental illness experience high rates of co-occurring substance use disorders and medical conditions and die on average 25 years younger than the general population. Homelessness is also a complex issue that can result from a number of factors and brings with it stigma and elevated morbidity and mortality.
