Usabilidade de um aplicativo assistencial para predição de pré-eclâmpsia no primeiro trimestre gestacional

Abstract

Pre-Eclampsia is a multisystemic and multifactorial disease of unknown cause, which is responsible for affecting the physiological pregnancy process, increasing maternal mortality levels in Brazil and around the world. PREApp® was developed in 2020 for healthcare professionals, with the purpose of predicting this disease in the first trimester of pregnancy. Considering the importance of evaluating user satisfaction with the use of PREApp®, this study aimed to evaluate the clinical usability of the application for predicting Pre-Eclampsia in the first trimester of pregnancy among professionals in the field. This is a methodological study, carried out between October and November 2023 with seven nurses from three Unidades de Atenção Primária à Saúde of the Coordenadoria Regional de Saúde V from Fortaleza, Ceará. To evaluate usability, the System Usability Scale was used and the data was analyzed using the Statistical Package for Social Sciences, arranged in tables. A space was also included for users to leave comments and/or suggestions regarding PREApp®. An excellent usability index of 87.14 points was obtained, comments regarding the difficulty in measuring patients' blood pressure in accordance with global recommendations and the amount of data requested by the patient's system, and suggestions regarding the system, which were well received by developers. It was concluded that PREApp® is a promising application. Furthermore, the usability evaluation study allowed a reflection on the practice of many professionals in the field and brought possibilities for improvements in the application to greater satisfaction of the target audience.
