Psychiatric Hospitalizations, Arrests, Emergency Room Visits, and Homelessness of Clients with Serious and Persistent Mental Illness: Findings from a Randomized Trial of Two ACT Programs vs. Usual Care
Abstract
Objective This investigation examined several adverse outcomes in clients with serious mental illness in a randomized trial of Assertive Community Treatment (ACT) versus usual care. Method 163 subjects were randomized to one of two ACT experimental conditions (staffed by consumers or non-consumers) or usual community care. Conditions were compared on psychiatric hospitalization, emergency room visit, arrest, and homelessness, within the two-year study period. Demographic, program, and client variables were examined for significant associations with outcomes. Results Significant differences were found between ACT and usual care in time to first arrest, but not hospitalization, homelessness or ER visits. Shorter time to first hospitalization was associated with male gender, diagnoses other than schizophrenia, high psychiatric symptomatology and lower provider case load. ER visits were associated with increased client symptomatology. Shorter times to homelessness were predicted by poorer therapeutic alliance between case manager and clients. Shorter time to first arrest was predicted by client minority status and enrollment in usual care. Conclusions The paucity of significant main effects may have been due to a prolonged "start-up" phase of the ACT programs, poor ACT implementation, restricted availability of psychiatric hospital beds, or changes in usual care services delivered over the study period.

“Interventions such as assertive community treatment (ACT) seek to prevent homelessness among individuals with mental illness and to address behavioral disorders (mainly substance use disorders, psychotic disorders, and depressive disorders [62]) and could help reduce the risk for arrest among homeless people (63).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
