Process map for FMEA risk analysis implementation by TG-100 of AAPM in Total Skin Electron Irradiation (TSEI) technique

Total Skin Electron Irradiation (TSEI) is a radiotherapy treatment which involves irradiating the entire body surface as homogeneously as possible. It is composed of an extensive multi-step technique in which quality management requires high consumption of resources. The TG-100 proposes a new perspective of quality management in radiotherapy, presenting a systematic method of risk analysis throughout the global flow of the stages through the patient. With the intention of applying this method, a multidisciplinary team of people was involved in the procedure that produced the process map (PM). This PM can be useful for those centers that intend to implement the TSEI technique. This is the first stage of a full risk analysis performed in a reference center in this treatment technique.
