Resumo
Com o passar dos anos, os equipamentos médicos têm sido cada vez mais utilizados nos centros de saúde, auxiliando em diagnósticos e procedimentos cirúrgicos. Dessa forma, faz-se necessário profissionais que sejam capazes de gerenciar essas máquinas, impedindo que elas causem risco ao paciente. É nesse cenário que surgiram os engenheiros clínicos, que são responsáveis por aplicar conhecimentos científicos e tecnológicos para auxiliar nas atividades clínicas da área da saúde. Uma forma de executar essa função é planejar as manutenções preventivas, que podem ser definidas como atendimentos planejados ao longo do ano, para evitar possíveis falhas dos equipamentos. Para definir a ordem das manutenções, costuma-se utilizar modelos de priorização, que são algoritmos criados para ranquear as máquinas. Na literatura, é possível encontrar pesquisas sobre modelos de priorização, no entanto, a maioria dos artigos visam descrever um único método, aplicando ele em um ambiente específico. Por conta disso, este trabalho tem como objetivo realizar a comparação de quatro métodos de priorização, facilitando no entendimento de seus conceitos e funcionamento. Os métodos selecionados foram: risk-oriented maintenance system (ROMSYS), o de Wang, o da American Hospital Association (AHA) e o de Anderson. Os modelos foram aplicados em um ambiente simulado e, ao final, foi observado que haviam muitas semelhanças entre os resultados, mesmo que a forma de avaliação fosse diferente. Por fim, é esperado que este trabalho promova o interesse de novos estudos comparativos do tema de priorização de manutenção preventiva, possibilitando que no futuro existam mais pesquisas relacionadas.
Over the years, medical equipments has become more used in healthcare facilities, assisting in diagnostics and surgical procedures. Therefore, it is necessary professionals capables to manage these machines, avoiding that they cause any risk to the patient. It is in this scenario that the emerged the clinical engineers, responsibles for applying scientific and technological knowledge to assist clinical activities in the health area. One way to perform this function is to plan preventive maintenance, which can be defined as planned appointments throughout the year, to avoid possibilities of equipment failures. To define the maintenance order, normally it is used prioritization models, which are algorithms created to rank the machines. In literature, it is possible to find researches about prioritization models, whoever, most articles describe just one method, applying it in a specific environment. For this reason, this article aims to compare four prioritization methods, facilitating the understanding of its concepts and operation. The selected models were: risk-oriented maintenance system (ROMSYS), by Wang, by American Hospital Association (AHA) and by Anderson. The models were applied in a simulated environment and, at the end, it was observed that there were many similarities between the results, even if the form of evaluation was different. Finally, it is expected that this work promotes the interest of others in the topic of preventive maintenance, enabling more related research in the future.
