Aplicativo móvel para registro de atendimento pré-hospitalar (APH) em tempo real

Abstract

Objectives: Development and validation of a mobile application for electronic registration of prehospital care (PHC), as a proposal to replace the paper filling in the form performed by health professionals in the occurrences attended. Methods: This is a cross-sectional, descriptive, cross-sectional technology assessment study with a quantitative analytical approach. The mobile application was built by the researcher herself, following the phases of software engineering, and it was evaluated by means of the application of questionnaires, among them, the System Usability Scale (SUS) questionnaire, a tool for verifying the usability level of a system. The application was evaluated between September and October 2019. Two evaluation questionnaires were created; one for health professionals and one for IT professionals. The assessment tools were available online on the Google Forms platform. The sample was for convenience, being invited IT professionals with experience in the area for over two years, and professionals working in pre-hospital care, nurses and nursing technicians who work at SAMU of São José do Rio Preto. Results: The app has screens (forms) to record patient identification and pre-hospital care registration providing more quality and agility, safe care, with voice command functions, including foreign languages (English and Spanish). This facilitates communication between staff and patient by providing important information such as patient identification, vital signs / history. If the information is recorded at the place of care, the application enables real-time monitoring of the patient's clinical condition by the regulatory team. In the evaluation of the application by the SUS instrument, it was possible, by means of a metric, to state that the APH Mobile application, object of this study, is according to the criteria such as: ease of the learning system (77.92) ± 0.09, system efficiency (75.76) ± 0.03, ease of memorization (66.67) error minimization (76.67) and user satisfaction (84.44) ± 0.06. The APH Mobile application SUS score of 76.67 ± 17.57 shows that the application meets the usability requirements of prehospital care professionals, however, it was identified that the criterion ease of memorization needs some adjustments, as it has received 66.67 points, slightly below the average cut of 68 points. It is noteworthy that the experience of using the application was satisfactory by prehospital care professionals, since the user satisfaction criterion was the best scored; 84.44 ± 0.06 points. Conclusions: The APH Mobile app has the ability to increase information processing efficiency through more immediate data collection when compared to paper logging. Thus, it will provide new possibilities for data analysis, resulting in care and management gains, from the availability of comprehensive, accurate and timely information, and it may contribute to proper decision making for the continuous improvement of the PHC system.
