Assessment of pediatric nurses' knowledge of budesonide-formoterol inhaler technique: a cross-sectional study in tertiary hospitals in China.

Background: Proper inhalation technique is essential for effective asthma management in children. Nurses play a critical role in educating patients; however, previous studies have shown variability in healthcare professionals' knowledge and inhalation device instruction skills, which may affect the quality of asthma education provided to patients. Objective: To assess pediatric nurses' knowledge regarding the use of the budesonide-formoterol inhaler and identify factors associated with higher knowledge scores. Methods: A cross-sectional survey was conducted among 57 pediatric nurses from tertiary hospitals in Nanning, Guangxi, China. A structured questionnaire based on expert consensus guidelines was used to assess theoretical knowledge regarding inhalation device use. Data were analyzed using descriptive statistics, chi-square tests, and one-way ANOVA. Results: The mean knowledge score was 85.07 ± 17.94, with 89.47% of participants achieving a score of ≥60, which was used as an institutional reference threshold for higher knowledge performance. Nurses working in specialized respiratory wards, those exposed to a higher proportion of asthma patients, and those receiving more frequent training demonstrated significantly higher scores ( Conclusion: Pediatric nurses demonstrated generally adequate knowledge of inhalation therapy; however, gaps remain. Targeted training and increased clinical exposure may improve knowledge and potential quality of patient education. The findings should be interpreted cautiously because the study was limited by convenience sampling, a small regional sample, and the lack of direct assessment of practical skills.
