Desenvolvimento de um protótipo de software para ensino-aprendizagem das classificaçÔes de enfermagem
INTRODUĂĂO: O processo de enfermagem (PE) proporciona maior autonomia e confiabilidade, visa melhorar a prĂĄtica profissional e documentar a assistĂȘncia. O PE contempla as classificaçÔes de enfermagem, diagnĂłsticos NANDA-I, as intervençÔes Nursing Interventions Classifications (NIC) e resultados Nursing Outcomes Classifications (NOC), por meio do cuidado baseado em evidĂȘncias. Para que o PE seja aplicado sistematicamente Ă© necessĂĄrio que seja transversal durante todo o ensino de graduação, tornando sua prĂĄtica comum para acadĂȘmicos de enfermagem, os futuros profissionais. A tecnologia educacional Ă© um recurso atual de aprendizagem, que apresenta resultados positivos no ensino, otimiza o tempo e torna o ambiente estimulante e dinĂąmico para discentes e docentes. Para a promoção de aprendizagem ativa das classificaçÔes de enfermagem, os sistemas informatizados tornam- se uma ferramenta conveniente para o ensino das ligaçÔes. Existe a necessidade de busca por metodologias ativas de ensino, centradas no estudante, alĂ©m da criação de formatos interativos para o ensino-aprendizagem do processo de enfermagem e suas classificaçÔes. OBJETIVOS: Construir um protĂłtipo de software de ensino-aprendizagem das classificaçÔes de enfermagem (diagnĂłsticos NANDA-I, intervençÔes NIC e resultados NOC) no processo de enfermagem para acadĂȘmicos; descrever as etapas de construção do protĂłtipo de software e elaborar um caso clĂnico para compor a base de dados do protĂłtipo. MĂTODO: pesquisa metodolĂłgica aplicada, com produção tecnolĂłgica de um protĂłtipo de software. O desenvolvimento do protĂłtipo foi baseado na metodologia ĂĄgil Scrum. O estudo foi realizado entre novembro/2019 e novembro/2020. RESULTADOS: na fase de construção do protĂłtipo denominado âWandaâ foram aplicadas as linguagens de programação adequadas Ă s etapas do sistema e Ă s funcionalidades requeridas. As funcionalidades previstas foram: inserção de sinais e sintomas para localização do diagnĂłstico de enfermagem, apresentação dos resultados de enfermagem (atual e metas a serem atingidas), planejamento de intervençÔes e atividades de enfermagem para a melhora do estado de saĂșde. O caso clĂnico foi desenvolvido a partir dos diagnĂłsticos, intervençÔes e resultados de enfermagem validados em consenso de especialistas, e publicados no artigo de Azzolin et al. (2012), que abordou a insuficiĂȘncia cardĂaca em contexto domiciliar. O banco de dados do protĂłtipo foi carregado com dois diagnĂłsticos de enfermagem oriundos do caso clĂnico validado: Volume de lĂquidos excessivo (00026) e Controle ineficaz da saĂșde (00080), bem como as intervençÔes e os resultados de enfermagem relacionados aos DEs e ao caso clĂnico. Para chegar Ă versĂŁo final, o protĂłtipo foi revisado e modificado em diversos ciclos, a fim de atender ao planejamento de suas funcionalidades. CONCLUSĂO: o estudo apresentou as etapas de construção do protĂłtipo de software Wanda, que buscou proporcionar um ambiente de aprendizagem dinĂąmico das classificaçÔes de enfermagem, a fim de incluir o acadĂȘmico como sujeito ativo do seu prĂłprio aprendizado frente a um caso clĂnico de uma paciente com insuficiĂȘncia cardĂaca grave, de etiologia idiopĂĄtica, que apresentava sobrecarga hĂdrica e controle ineficaz da saĂșde durante avaliação em consulta domiciliar.Resumo nĂŁo disponĂvel
