Gender differences in hospitalization after emergency room visits for depressive symptoms.

BACKGROUND: Depressed women have greater than three times the odds of hospitalization as clinically comparable men. The objective of this study is to understand if these gender differences emerge in admissions decisions after depressed individuals' arrival at the emergency room (ER).
METHODS: We used multivariate logistic regression to examine gender differences in hospitalization after 6266 ER visits for depressive symptoms in the nationally representative 1998-2007 National Hospital Ambulatory Care Medical Survey.
RESULTS: ER visits by depressed women have only 0.82 the odds of hospitalization (95% confidence interval [CI] 0.70-0.96, p=0.02) in models adjusted for sociodemographic, clinical, and system covariates. Sensitivity analyses demonstrate gender differences in visits by patients with no injury but not in visits by patients with self-inflicted injury.
CONCLUSIONS: These findings suggest that admission decisions after ER visits are not responsible for the increased risk of hospitalization previously reported in depressed women, as ER visits by women with depressive symptoms actually have lower odds of hospitalization than visits by men. We encourage further research to explore the causes and consequences of this practice pattern to move toward rational delivery systems committed to providing comparable treatment to clinically comparable individuals regardless of gender.
