Abstract
BACKGROUND: Improper inhaler technique negatively impacts asthma control, yet data on this issue in Vietnam remain limited. This study assessed the prevalence and impact of improper inhaler technique on pediatric asthma control and examined the role of caregivers in this context. METHODS: An analytical cross-sectional study was conducted among children with asthma and their caregivers. Logistic regression analyzed associations between improper inhaler technique, uncontrolled asthma, and caregivers' attitudes and practices in asthma management. RESULTS: Among 186 children, 45.2% had improper inhaler technique, which was independently associated with uncontrolled asthma (AOR = 2.33, 95% CI: 1.27-4.3, P = .006). Regarding caregivers, failure to ensure adherence to prescribed controller medications and inadequate monitoring of remaining MDI medication were significantly associated with improper technique (P < .05). CONCLUSION: Improper inhaler technique is common and associated with poor asthma control. Caregivers' involvement in medication adherence and monitoring plays a crucial role in addressing this issue.
