Pdf Summary
This retrospective chart review analyzed 287 patients discharged from Mount Sinai Behavioral Health Center between January and March 2024 to identify factors predicting psychiatric readmission within one year. Among the patients, 21.3% (61 individuals) experienced at least one psychiatric readmission. Comparisons revealed that readmitted patients had significantly higher unemployment rates (90% vs. 74%), were more often residing in group homes or supportive housing (16% vs. 5%), and had a greater history of prior psychiatric hospitalizations (mean 3.2 vs. 1.9).<br /><br />Interestingly, while no difference was found in the overall history of substance use between groups, those readmitted had a notably lower proportion of positive urine drug screens (20% vs. 40%). Logistic regression identified employment status, domicile, number of prior hospitalizations, and urine drug screening as significant predictors of readmission, with the model showing strong statistical significance.<br /><br />Previous studies suggested that co-occurring substance use disorders (SUDs) increase psychiatric readmission risk, often doubling readmission rates when combined with mental illness (Morel et al., 2020). However, this study's finding that positive urine drug screens correlate with reduced readmission odds is counterintuitive. The authors propose that patients with positive drug screens might receive more focused interventions or monitoring, thereby potentially lowering their readmission risk. This contrasts with earlier inconsistent findings possibly due to uncontrolled confounders (Drake et al., 2004; Kessler et al., 2005).<br /><br />Unemployment and history of multiple hospitalizations emerged as robust predictors, emphasizing the importance of comprehensive discharge planning and socio-environmental support to mitigate readmission risks. These insights highlight the complex, multifactorial nature of psychiatric rehospitalization and may inform targeted clinical practices and policies aimed at improving patient outcomes and reducing readmissions.
