Desenvolvimento e validação de aplicativo para ensino de abordagem da dor em cuidados paliativos / Development and validation of mobile application for teaching the subject of pain management in palliative care

Resumo Introdução: Avaliação e manejo adequados da dor têm se tornado uma preocupação cada vez maior dos profissionais de saúde. Segundo a definição de cuidados paliativos da Organização Mundial da Saúde, são importantes a identificação precoce, a avaliação e o tratamento da dor. Objetivo: Este estudo teve como objetivos desenvolver e avaliar um aplicativo para dispositivos móveis voltado para o ensino de abordagem da dor em cuidados paliativos. Método: Foi desenvolvido um aplicativo móvel, seguido de sua utilização por médicos residentes e de avaliação qualiquantitativa prospectiva. Aplicou-se o teste de conhecimento. Obtiveram-se a usabilidade do aplicativo, por meio da System Usability Scale (SUS), e a satisfação, por meio do Net Promoter Score (NPS). Os dados foram tabulados no Microsoft Office Excel® e exportados para o software Statistical Package for the Social Sciences (SPSS) versão 20.0 (IBM): na realização das análises, adotou-se uma confiança de 95%. Para a análise qualitativa das avaliações, o conteúdo das respostas foi transcrito e organizado em nuvens de palavras para destacar as ideias centrais. O estudo foi aprovado pelo Comitê de Ética do Centro Universitário Christus. Resultado: Desenvolveu-se o PaliPain App, aplicativo constituído de casos clínicos de pacientes em cuidados paliativos com manifestações de dor, além de questões, vídeos e imagens, disponibilizado nas plataformas Android e iOS. Utilizaram o aplicativo 13 médicos residentes. A média de acertos de questões no pré-teste sobre dor em cuidados paliativos aumentou de 6,08 para 7,54 após manuseio do aplicativo. Na avaliação sobre a usabilidade do aplicativo, obtivemos na SUS uma média de 89,2, acima do nível considerado adequado de 70,0. Na avaliação de satisfação, 54% dos médicos responderam com pontuação 10 à pergunta: "Em uma escala de 0 a 10, quanto você recomendaria o aplicativo PaliPain a um amigo ou colega?". Conclusão: O PaliPain App, desenvolvido e disponibilizado nas plataformas Android e iOS, foi bem avaliado pelos médicos residentes, apresentando ótimos escores de usabilidade e de satisfação. Identificamos que houve ganho de conhecimento, com pontuação média na resolução de questões aumentando de 6,08 para 7,54 após livre uso da aplicação. O PaliPain App pode ser uma ferramenta útil para ensino de abordagem de dor para médicos residentes.

Abstract Introduction: Pain evaluation has become an increasingly relevant concern for healthcare workers. According to the World Health Organization's definition of Palliative Care, early identification, evaluation, and treatment of pain are important. Objective: Developing and rating an app for mobile devices that focuses on teaching the subject of pain management in Palliative Care. Research Methodology: The app was developed as a learning tool and tested by resident physicians while undergoing a qualitative and quantitative prospective evaluation. Mock tests were taken. The usability of the app was rated through the System Usability Scale (SUS), and satisfaction with the app was rated through the Net Promoter Score (NPS). The data was charted by using Microsoft Office Excel ® and was exported to the Statistical Package for the Social Sciences (SPSS) version 20.0 (IBM) software: an analysis was run with a 95% confidence interval. As for the qualitative analysis of the resident physicians' evaluations, all available content was transcribed and properly organized in word clouds in order to highlight the most important pieces of feedback that the physicians presented regarding the app. The study was approved by the Ethics Committee. Main Results: The PaliPain App was developed as a database filled with clinical cases of patients undergoing palliative care who were experiencing varying levels of pain, and also presents analysis of test questions, videos and images. It was made available for the Android and iOS platforms. The average correct answers in a mock test about pain management during palliative care rose from 6.08 to 7.54. Thirteen resident physicians made use of the app. In the evaluation of the app's usability, the average SUS score was 89.2. In the evaluation of user satisfaction, 54% of the resident physicians answered the question "from a scale of 0 to 10, what is the likelihood of you recommending the PaliPan app to a friend or colleague?" with a score of 10. Conclusion: The PaliPain App, developed and available on Android and iOS platforms, was well evaluated by resident physicians, presenting excellent scores for both usability and satisfaction. We identified that there was a gain in knowledge, with an average score in the resolution of questions increasing from 6.08 to 7.54 after free use of the application. The PaliPan app could be a useful tool to teach the subject of pain to resident physicians.

Development and perceived usability evaluation of an interactive smartphone application for the teaching of hemodynamics and evaluation of arterial pulse pressure variation.

BACKGROUND: The use of fluids is the most frequently used therapy for circulatory shock. Its inadequate use has adverse effects, requiring hemodynamic goals, highlighting the use of pulse pressure variation due to its high accuracy. One of the problems related to this method is the difficulties in measuring the pulse pressure variation (PPV) in most monitors for clinical use. We assessed the qualitative aspects of perceived usability of a smartphone application (app), which, based on a photograph of the patient's arterial pulse wave, can help measure PPV and help in the diagnosis and management of shock cases. METHODS: To assess the software perceived usability, we used the System Usability Scale (SUS) applied to 30 physicians in 2 tertiary hospitals in Brazil. The software accuracy was measured using a sequence of 3 images with different values ​​of pulse pressure variation, comparing the obtained values ​​ with the gold standard. The educational interface of the app was evaluated qualitativelyfrom the spontaneous testimonies of the selected test participants.The project was approved by the Research Ethics Committee of Centro Universitário Christus. RESULTS: The analysis showed an average SUS of 86.3 points on a scale of 1-100 (above 80.3 is considered the best in terms of interface). The assessment of the application's accuracy when evaluating pulse pressure variation showed that the average variation of the measurements taken by the participants was small, with a good measure of repeatability and reproducibility. The app's educational interface was qualitatively evaluated, being praised by the users. CONCLUSIONS: It can be concluded that the developed mobile application showed excellent qualitative aspects of perceived usability results. More studies with this app will be required to evaluate the potential to help professionals with hemodynamic evaluation in emergency and intensive care settings.
