Purpose:
To determine the extent and cost of hospitalizations for mental illness among adolescents and to identify differences in acute care hospital use by gender and between racial/ethnic groups.
Methods:
Analysis of discharge data for adolescents, 10 to 19 years of age (n = 27,595), with a principal diagnosis of mental illness from acute care hospitals in California in 1994. Relative risks (RRs) were calculated by race/ethnicity and gender and stratified by race/ethnicity and payment source.
Results:
Mental illness accounted for 14.8% of hospitalizations in this age group; the mean length of stay was 10.9 days. Total charges exceeded $300 million. Overall, adolescent boys had a slightly lower risk of hospitalization for mental illness than did adolescent girls (RR = 0.90, 95% confidence interval [CI] = 0.87, 0.92) but a higher risk for certain diagnoses. Overall, nonwhite adolescents had a lower risk of hospitalization for mental illness than did white adolescents: African-Americans (RR = 0.77, 95% CI = 0.74, 0.81), Latinos (RR = 0.32, 95% CI = 0.31, 0.33), and Asians/others (RR = 0.27, 95% CI = 0.26, 0.29). These differences remained significant after stratification by payment source.
Conclusions:
The risk of hospitalization for mental illness among adolescents varies by specific mental illness and by race/ethnicity. In light of the significant human and financial costs associated with hospitalization for mental illness, further research into the determinants of illness and the options for care is warranted.
