Methods This is a randomized single-blind study comparing transitional case management after discharge with routine post-hospitalization care for subjects living independently without institutional psychiatric follow-up. Demographic and clinical data will be gathered during hospitalization, and 1, 3, 6 and 12 months after discharge. Quantitative assessment of outcomes using validated instruments will be: contact and level of adherence to outpatient care (primary outcomes), as well as number of hospitalization days, number of readmissions, severity of illness and satisfaction with care (secondary outcomes).
