Less is known, however, about the relationship between psychiatric disorders and repeat hospitalizations for youth with diabetes. RESEARCH DESIGN AND METHODSWe performed a retrospective cohort study using data from the Pediatric Health Information System, which included detailed discharge data from 37 noncompeting childrens hospitals in the U.S. Using logistic regression, we examined whether the presence of coded diagnoses for internalizing or externalizing disorders at an index hospitalization for diabetes was associated with increased risk for rehospitalization during follow-up (duration of follow-up ranged from 3 to 24 months). The analysis was stratified by age-groups, and we controlled for potential confounders including sex, age, race/ethnicity, type 1 versus type 2 diabetes, Medicaid status, intensive care unit utilization, length of stay during index admission, and duration of follow-up.
RESULTSAmong adolescents aged 1318, internalizing disorders were associated with significantly increased odds of rehospitalization (odds ratio 1.79 [95% CI 1.272.52]); the point estimate for externalizing disorders was similar, but the finding was not statistically significant at the CONCLUSIONSInternalizing disorders are associated with increases in repeat hospitalizations for diabetes among adolescents. Future research is needed to explore the reasons for this finding, such as degree to which treatment nonadherence mediates this relationship and whether appropriate treatment of internalizing disorders results in improved diabetes outcomes and decreased readmissions.
