Resumo
Objetivo: Avaliar a usabilidade de um protótipo de aplicativo móvel para educar e gerenciar indivíduos submetidos à cirurgia bariátrica. Métodos: Estudo exploratório quantitativo realizado em um ambulatório público especializado em obesidade no Brasil. Pacientes em pré e pós-operatório de cirurgia bariátrica foram convidados a usar o aplicativo por uma hora e avaliaram sua usabilidade através da Escala de Usabilidade do Sistema (SUS). Resultados: Dos 31 participantes, 84,0% eram mulheres, com idade média de 42,2 (±12,4) anos. A maioria dos participantes (97,0%) possuía níveis de escolaridade fundamental ou médio. Da amostra total, 12 (38,8%) estavam no pré-operatório e 19 (61,2%) no pós-operatório. A pontuação geral média de usabilidade do aplicativo foi de 75,5 (DP 11.0). Os participantes classificaram a usabilidade como Boa (34,2%), Excelente (51,4%) e Melhor Possível (14,4%). Não foi encontrada diferença significativa nos escores de usabilidade entre diferentes níveis educacionais (p 0,654) e níveis de renda (p 0,088), exceto por uma diferença estatisticamente significativa entre adultos mais jovens e mais velhos (p 0,014). Conclusão: O aplicativo foi considerado útil pelos pacientes obesos como uma ferramenta para aprendizado e auxílio na navegação pelos cuidados bariátricos.
