Objective: To investigate the current status of aerosol inhalation medication in the pediatric outpatient of the Third Affiliated Hospital of Zhengzhou University

to analyze and evaluate its rationality

so as to provide reference for clinical rational drug use. Methods: Retrospective analysis was conducted by extracting data from the hospital information system on 1

017 prescriptions for aerosol inhalation medication in pediatric outpatient from Jan. to Mar. 2022. Statistical analysis was performed on gender

age

clinical diagnosis

types of nebulizers

dosage

and drug combination to evaluate the rationality of aerosol inhalation medication in pediatric outpatient. Results: Among the 1

017 prescriptions for aerosol inhalation medication

20. 16% were for single drug

56. 05% for dual medication

and 23. 78% for triple medication. Glucocorticoids were the most widely used among all aerosol inhalation medication

with a utilization rate of 87. 61%. Prescriptions with aerosol and oral medications accounted for 28. 52%. Aerosol inhalation medication was primarily used for 22 clinical diagnoses

including respiratory infections

bronchitis

pneumonia

asthma and laryngitis. The proportion of irrational prescriptions was 3. 15%

mainly for inappropriate indications and unsuitable drug selection. Conclusion: Combination therapy with aerosol inhalation is common in pediatric outpatient of our hospital

and medication usage generally aligns with treatment guidelines. The expanded use of drugs is supported by evidence-based medicine

demonstrating rationale utilization. However

there are instances of irrational drug use that need further standardization.
