Resumo
Objetivo: Desenvolver e avaliar o aplicativo JOIA®, analisando seu impacto na autoconsciência e prevenção em saúde, além de sua usabilidade, segurança e privacidade no sistema público de saúde. Métodos: O estudo ocorreu em duas etapas: 1) desenvolvimento do JOIA® (para Android e iOS); 2) estudo intervencionista antes e depois, realizado em um hospital universitário público no sul do Brasil, com 100 pacientes acima de 50 anos. Foram avaliadas usabilidade (System Usability Scale - SUS) e conformidade com a Lei Geral de Proteção de Dados Pessoais (LGPD). Resultados: 90% dos pacientes baixaram e usaram o App, 95% consideraram útil e 93% demonstraram interesse em continuar usando. A autoconsciência aumentou 5 vezes, a satisfação com a saúde 32 vezes e o reconhecimento da prevenção 3,6 vezes. Conclusão: O App JOIA® facilitou a comunicação entre pacientes e profissionais, garantindo segurança conforme a LGPD. 68% avaliaram a usabilidade como intermediária a excelente, indicando áreas para melhorias na interface e suporte ao usuário. O App demonstrou-se eficaz para engajamento e prevenção em saúde, com potencial para otimizar o sistema público e reduzir custos.
