Abstract

Objective: This study aimed to evaluate inhaled corticosteroid (ICS) adherence and identify factors associated with nonadherence in pediatric asthma patients. Methods: A total of 134 patients aged 8–18 years old were included. At the first visit, patient adherence, asthma knowledge, and outcome expectation data were collected and recorded. Depression, anxiety, and self-esteem were assessed using psychiatric questionnaires. After providing asthma education, reevaluation of adherence and asthma control was performed at one 3- to 6-month follow-up visit. Results: The mean ICS adherence was 75.9 ± 27.5%. Fifty-seven patients (42.5%) were defined as having poor adherence (<75%). “Intentional” and “hectic lifestyle and forgetfulness” were the main reasons for missing ICS doses in mid-late adolescents and children, respectively. Asthma knowledge generally improved with age. Overall, 89% and 67.7% of patients could define symptoms and triggers of asthma, respectively; however, less than 25% understood how asthma affected their body and the chronic nature of asthma. Patients with ICS adherence <75% had unfavorable expectations from asthma treatment (odds ratio [OR]: 1.05, 95% confidence interval [CI]: 1.01–1.10), and a higher proportion of inhaled short-acting beta-agonist use before exercise (OR: 4.12, 95% CI: 1.27–13.36). Depression and anxiety were frequently found (27.5%) and 23.3%, respectively; p > 0.05). Significant improvement in ICS adherence (p = 0.02) and Asthma Control Test scores (p = 0.02) were observed at the follow-up visit. Conclusions: Patient outcome expectations could be predictors of ICS adherence. Patient education regarding the mechanism and nature of asthma should be considered as an intervention for improving pediatric patient adherence. Psychological evaluation is warranted in pediatric patients with asthma.
