BackgroundRates of psychiatric disorders and related hospitalizations among youth in the United States have risen substantially over recent decades. Despite evidence supporting outpatient care, fewer than half of youth receive treatment. When outpatient management is insufficient, inpatient psychiatric hospitalization is required, though it is costly, disruptive, and limited in availability. Prior research on predictors of inpatient length of stay has been dated and heterogenous, highlighting the need to identify current clinical and non-clinical factors associated with prolonged stays among youth populations.MethodThis IRB-approved retrospective study reviewed the medical records of 1,101 child and adolescent patients admitted to an inpatient psychiatric unit between June 1, 2018, and November 30, 2021. Baseline sociodemographic and clinical data were collected, and LOS was categorized into three groups: below-average (0-6 days), average (7-14 days), and above-average (15+ days). Comparative statistics were performed, and linear regression was used to identify independent predictors of LOS.ResultsThe average LOS was 10.5 days. Significant predictors of prolonged LOS included public insurance, admission for psychosis or suicide attempt, involvement of child protective services, number of prior hospitalizations, and number of medications prior to admission.ConclusionProlonged LOS in psychiatrically hospitalized youth is associated with specific clinical and non-clinical factors. Identifying these predictors at admission can guide treatment planning and set realistic expectations for families. Further research is required to validate these findings and explore the impact of LOS on treatment outcomes.
