Introdução: As transfusões sanguíneas, embora populares, têm sido associadas a piores desfechos clínicos em diversos estudos. Por tais motivos, métodos de Gerenciamento de Sangue do Paciente têm sido promovidos, inclusive pela OMS, dentre os quais se encontra a Hemodiluição Normovolêmica Aguda (HNA). Embora a HNA tenha demonstrado eficácia e segurança em reduzir transfusões, ela ainda é pouco utilizada. Uma das maneiras de se difundir um procedimento na prática médica é tornando-o mais conhecido através de websites e aplicativos. Objetivo: Desenvolver um webapp que possibilite equipes cirúrgicas utilizarem a técnica de HNA. Método: A pesquisa seguiu a metodologia Design Thinking. Em Descobrir, foram realizadas busca de anterioridade, levantamento bibliográfico, seleção de artigos e confecção de questionários. Em Definir, os artigos selecionados foram organizados, os questionários aplicados aos especialistas, identificando as “dores” e, então o conteúdo do aplicativo foi elaborado e revisado pelos participantes. Em Desenvolver, foi produzido o protótipo do webapp e realizado o processo de validação por especialistas e pelo público-alvo. Em Entregar, o aplicativo foi disponibilizado ao público. Resultados: A busca apresentou 14.775 artigos que, após aplicação dos critérios de exclusão, resultou em 54 artigos. Após resposta aos questionários, prototipagem e validação do produto por especialistas, apresentando um índice da Validação de conteúdo de 100%, o webapp foi avaliado pelo público-alvo através do questionário validado SUS, obtendo pontuação de 92,5 e então disponibilizado de forma online. Conclusão: Foi desenvolvido e validado um aplicativo que possibilita que equipes cirúrgicas utilizem, na prática, a técnica de HNA, o HNA App.
Introduction: Blood transfusions, although popular, have been associated with worse clinical outcomes in various studies. For these reasons, Patient Blood Management (PBM) methods have been promoted, including Acute Normovolemic Hemodilution (ANH), endorsed by the WHO. Although ANH has demonstrated efficacy and safety in reducing transfusions, it is still underutilized. One way to disseminate a procedure in medical practice is by making it more widely known through websites and applications. Objective: To develop a web app that enables surgical teams to use the ANH technique. Method: The research followed the Design Thinking methodology. In the Discover phase, prior art searches, literature reviews, article selection, and questionnaire creation were conducted. In the Define phase, selected articles were organized, questionnaires were applied to experts, identifying "pain points," and then the app's content was developed and reviewed by participants. In the Develop phase, the web app prototype was produced and validated by experts and the target audience. In the Deliver phase, the app was made available to the public. Results: The search yielded 14,775 articles, which, after applying exclusion criteria, resulted in 54 articles. After responding to questionnaires, prototyping, and validating the product by experts, with a 100% Content Validation Index, the web app was evaluated by the target audience using the validated SUS questionnaire, scoring 92.5, and then made available online. Conclusion: An app, the HNA App, was developed and validated, enabling surgical teams to use the ANH technique in practice.
