The study hypothesizes that early housing after hospitalization with case management integrated into the health and housing systems, will results in decreased use of costly health services (i.e., hospitalizations and Emergency Room visits) with no negative affect on health. To address this hypothesis the investigators implemented a Randomized controlled trial of 407 homeless adults with chronic medical illness in Chicago. Eligible homeless adults were enrolled during a hospitalization to intervention - Early housing with case management - or usual care - usual case management and housing options.
