Análise de risco em Radioterapia: aplicação da ferramenta FMEA ao controle da qualidade do acelerador linear

Abstract

The first technological development of radiotherapy with the technique of filling menstruation methods, updating linear systems and computational advances, increased the complexity of the treatments. All rights reserved for quality and recovery for the potential of miracles the probabilities of keys during the treatment. This work was mapped and the risk associated with the linear linear accelerator with an application of the tool of FMEA. The work was developed in a radiotherapy center, located in the southern region of the country. A QC Process Map has been identified. After the idendification of the map, a spreadsheet was developed with steps, failure modes and causes associated with parameters related to severity, severity and detectability. An FMEA spreadsheet was then implemented for all subprocesses identified on the map. The results of the ranking of the fault of the NPRs≥ 100. The efficiency of the FMEA was identified in the identification of types of failures, high priority causes, for the implementation of safety measures in the Quality Management Program. The constancy sub-process of the reference dose presented a greater representativeness of potential failure modes with a high degree of priority, ascertained at different stages of the result. The study aims at the security strategies are implemented, from the results obtained for the first 10 failure modes of the NPR ranking.
