RESUMO

There are data in the literature indicating that the administration of medications such as inhaled corticosteroids and bronchodilators, using metered-dose inhalers, is more effective and safer than its dispensation by conventional nebulizers. However, there is evidence that not only patients but also health care professionals have difficulty in dealing with pressurized dose inhalers. The hypothesis of the present study is that the knowledge of inhalation techniques among health professionals of our Institution is heterogeneous, and there is no information about this knowledge among the diverse categories of professionals. OBJECTIVE: To assess the practical and theoretical knowledge of medical professionals, nursing and physiotherapy on the use of metereddose inhalers by standardized testing. 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. 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 diverse professional categories. Following the examination, oral and written instructions on the correct use of the devices were provided for all participants. 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 146 professionals were assessed, including 30 fellows in pediatrics, 23 attending physicians, 29 physical therapists, 33 nurses and 31 nursing assistants. Fellows or attending physicians of the Pediatric Pulmonology Unit were not included in the study. Fellows, physical therapists and attending physicians performed significantly better than did nurses and nursing assistants. Only fellows had a median score greater than six. On the practical tests for infants and toddlers, the step most often missed was that related to cleaning the spacer. On practical tests, the steps related to shaking the inhaler and cleaning the mouth also presented high error indices. On the written tests, the question most often answered incorrectly was that related to the waiting time between puffs. CONCLUSIONS: The theoretical and practical knowledge of health professionals of our Institution on the use of metered-dose inhalers is heterogeneous. The performance of fellows, physical therapists and attending physicians was significantly better than that of nurses and nursing assistants who are directly involved in the practical application of these devices in the hospital routine.
