ObjectivesPediatric mental illness poses a significant burden with an overall prevalence of approximately 10%. Increasingly, children with mental disorders seek care in the emergency department (ED). However, the ED is not an ideal setting. Pediatric mental health patients receive limited treatment and experience significantly longer length of stay (LOS) than other patients seen in the ED. This study examines patient and hospital factors associated with LOS and prolonged LOS (PLOS).MethodsThis is a retrospective chart review of patients between the ages of 3 and 17 presenting at 2 participating urban EDs with a psychiatric diagnosis from May 2010 to May 2012.ResultsThis study includes 939 patients with an average age of 14.1 years and a median LOS of 295 minutes. The diagnosis was the strongest predictor of LOS and PLOS. Patients with a psychotic disorder or suicide attempt or ideation experienced a longer LOS, 35% and 55% increases, respectively, and an increased odds of PLOS (odds ratio, 3.07 and 8.36, respectively). Patient sex, previous history of self-harm, and the daily census were associated with both a longer LOS and PLOS. Ethnicity, site of admission, and year of admission were only associated with LOS.ConclusionsDiagnosis-specific management factors are the primary determinant of LOS. However, some patient characteristics and hospital operational factors are also associated with LOS. Organizational reforms and an evaluation of the required human and material resources are necessary to improve access to and availability of pediatric mental health care.
