Depression, Anxiety, and Emergency Department Use for Asthma.

Abstract

Asthma is responsible for ∼1.7 million emergency department (ED) visits annually in the United States. Studies in adults have shown that anxiety and depression are associated with increased asthma-related ED use. Our objective was to assess this association in pediatric patients with asthma. We identified patients aged 6 to 21 years with asthma in the Massachusetts All-Payer Claims Database for 2014 to 2015 using <i>International Classification of Diseases, Ninth and 10th Revision</i> codes. We examined the association between the presence of anxiety, depression, or comorbid anxiety and depression and the rate of asthma-related ED visits per 100 child-years using bivariate and multivariable analyses with negative binomial regression. Of 65 342 patients with asthma, 24.7% had a diagnosis of anxiety, depression, or both (11.2% anxiety only, 5.8% depression only, and 7.7% both). The overall rate of asthma-related ED use was 17.1 ED visits per 100 child-years (95% confidence interval [CI]: 16.7-17.5). Controlling for age, sex, insurance type, and other chronic illness, patients with anxiety had a rate of 18.9 (95% CI: 17.0-20.8) ED visits per 100 child-years, patients with depression had a rate of 21.7 (95% CI: 18.3-25.0), and patients with both depression and anxiety had a rate of 27.6 (95% CI: 24.8-30.3). These rates were higher than those of patients who had no diagnosis of anxiety or depression (15.5 visits per 100 child-years; 95% CI: 14.5-16.4; <i>P</i> < .001). Children with asthma and anxiety or depression alone, or comorbid anxiety and depression, have higher rates of asthma-related ED use compared with those without either diagnosis.
