[Evaluation of the knowledge of health professionals at a pediatric hospital regarding the use of metered-dose inhalers].

OBJECTIVE: To evaluate health professionals working at a tertiary pediatric hospital in terms of their knowledge regarding the practical use of metered-dose inhalers.
METHODS: Practical and written tests on the use of metered-dose inhalers were applied to physicians, physical therapists, nurses and nursing assistants. A score from 0 to 10 was assigned to each evaluation, and median scores were calculated for each professional category. Questions with higher and lower correct values were identified, and a descriptive comparison was made regarding the performance of the various professional categories. Statistical analysis was performed using the Kruskal-Wallis method for comparison of medians. A sequential logistic multiple regression analysis was also performed.
RESULTS: A total of 30 resident physicians or interns in the pediatrics department, 23 attending physicians, 29 physical therapists, 33 nurses and 31 nursing assistants were evaluated. Resident physicians, physical therapists and attending physicians performed significantly better than did nurses and nursing assistants. Only resident physicians had a median score greater than 6.
CONCLUSIONS: The health professionals evaluated, particularly the nurses and nursing assistants, who are directly involved in the practical use of metered-dose inhalers, possess insufficient knowledge regarding the use of such inhalers.
