IntroductionThe use of vests for handling medication (prescription, preparation, and dispensing) in the emergency department is a strategy designed to increase patient safety by reducing interruptions and, consequently, medication errors. In this study, we aim to assess how professionals perceive the use of vests in a pediatric emergency department of a tertiary hospital.Material and MethodsA cross-sectional survey was conducted among pediatric emergency physicians and nurses in October and November 2019. We analyzed the results of a 19-item survey on the perception of vests as a tool for reducing interruptions and medication errors.ResultsIn this study, 91 surveys were delivered and 89 (97.8%) were completed. One hundred percent of the professionals were aware of the vests. Nurses reported the following reasons for not using the vest: high workload (25%) and preparation of nebulized and oral medications (25%). One hundred percent of doctors asked for the vest because of forgetfulness. Thirty-five physicians (81.4%) and 17 nurses (85.0%) said that wearing the vest, they were rarely or never interrupted. Eighty-two respondents (93.2%) agreed that vests are an effective strategy for minimizing medication errors.ConclusionsAlthough medical professionals consider vests to be a useful strategy to prevent interruptions and reduce medication errors, adherence to the protocol is low, so a promotion strategy is needed to encourage professionals to use the vests.
