Among previously institutionalized PSH participants, PSH was associated with more inpatient stays and emergency department visits but fewer primary care visits; no significant associations were found among non-institutionalized participants.
Average treatment effect on the treated (ATT) weighting was used to address confounding from non-random program assignment, and zero-inflated negative binomial models estimated outcomes. Among previously institutionalized PSH participants, PSH was associated with 0.12 more predicted inpatient stays, 1.0 more predicted ED visits, and 3.1 fewer predicted primary care visits. The authors noted that nearly 80% of comparison members in the institutionalized subgroup remained institutionalized during follow-up, and observed differences may reflect community versus institutional care access rather than PSH program effects.
