Identificação de alta demanda de manutenção corretiva em equipamentos de radiodiagnóstico e determinação de desempenho através de fator de influência

Abstract

Radiodiagnostic systems play a very important role for medical definitions, in such way that they directly support the diagnosis and choices of appropriate treatments for a patient. Therefore, its use has become increasingly common and due to its impact on public health, it is understood that a maintenance management of those equipments must be well performed to guarantee a high quality and reliability of the diagnostics exams. The present work aims to evaluate the quality and performance of radiodiagnostics equipments of one company, in accordance with the demands of their corrective maintenance during the period of one year. Initially, a general evaluation of X-ray, mammography, computed tomography and advanced therapies modalities was carried out. Among those modalities, it has been observed that computed tomography presented the highest number of corrective maintenance occurrences per unit of active equipment. Thus, when conducting an in-depth analysis of these equipments, it was verified that there is no correlation between the Brazilian regions and the occurrences of corrective maintenance. CT scans were also separated by models and through the creation of a metric called 'Corrective maintenance occurrence indicative (IOMC)', it was possible to evaluate the influence by the age and size of the installed base into the incidences of corrective maintenance. The H, P, D, O and S models did not perform as expected, with four models being relatively new equipment, up to 7 years of age.
