Aplicação do índice de qualidade a partir de uma análise de risco para radiocirurgia intracraniana

Abstract

The standard in Quality Management (QM) of radiotherapy by the Medical Physics community, until recently, has acted in the technical performance of the radiotherapy equipment. In recent years, however, it has been recognized that a major source of quality and safety deficiency arises from weakness or variability in radiotherapy processes. The wide variability in processes requires a much greater degree of customization than should be realized by those with intimate knowledge of the processes themselves. TEIXEIRA, Flávia Cristina da Silva, based on a failure mode and effect analysis based on the Process Map and FMEA technique used by TG 100 / AAPM, proposed the evaluation of the "Quality Index" (IQ) in her thesis "Study and development of a model of risk analysis for intracranial radiosurgery ", applying the FMEA tool, and relating to the Risk Priority Number (NPR) and Severity Index (IS) for each subprocess and then to the process of complete radiosurgery. The purpose of the paper is to apply the FMEA risk analysis tool to Quality Management (QM) and to determine the Quality Index (IQ) based on process risk. Given the complexity in the process of Radiosurgery, the Quality Management (QM) as well as its quantitative analysis becomes a fundamental tool for the safety of the delivery of the dose to the patient. Our study also aims to identify and apply security strategies according to the failure modes ranking obtained through the FMEA and to re-evaluate the most critical subprocesses as well as the process as a whole, enabling a quantitative analysis of the Management Program of the Quality (QM) to also serve as a parameter to an internal or external audit program.
