OBJECTIVE
To compare pediatric mental health emergency department visits to other pediatric emergency department visits, focusing on length of stay.
METHOD
We analyzed data from the National Hospital Ambulatory Medical Care Survey, a nationally representative sample of US emergency department visits from 2001–2008, for patients aged ≤ 18 years (n=73,015). Visits with a principal diagnosis of a mental disorder (n=1,476) were compared to other visits (n=71,539) with regard to patient and hospital characteristics, treatment and length of stay. Predictors of prolonged mental health visits were identified.
RESULTS
Mental health visits were more likely than other visits to arrive by ambulance (21.8% vs. 6.3%, p<.001), be triaged to rapid evaluation (27.9% vs. 14.9%, p<.001), and be admitted (16.4% vs. 7.6%, p<.001) or transferred (15.7% vs. 1.5%, p<.001). The median length of stay for mental health visits (169 minutes) significantly exceeded that of other visits (108 minutes). The odds of extended stay beyond four hours for mental health visits was almost twice that for other visits (adjusted odds ratio 1.9, 95% CI 1.5–2.4) and was not explained by observed differences in evaluation, treatment or disposition. Among mental health visits, advancing calendar year of study, intentional self-injury, age 6–13 years, Northeastern, Southern, and metropolitan hospital location, use of laboratory studies, and patient transfer all predicted extended stays.
CONCLUSIONS
Compared to other pediatric emergency visits, mental health visits are longer, are more frequently triaged to urgent evaluation, and more likely to result in patient admission or transfer, thereby placing distinctive burdens on US emergency departments.
