[Events and errors in radiation oncology: Conciliating perspectives to support care]

The term "event" covers a wide range of concrete situations in radiation oncology, from particularly intense radiation-related side effects to the possibility of technical or human error. Although quality procedures are an integral part of radiotherapy oncology department operations ensuring the analysis and prevention of such events, their occurrence during radiation treatment still has a significant impact on patients and their experience of the treatment process, as well as on health professionals. These practical, emotional and symbolic impacts are all the greater when the event occurs in the aftermath of an error. The ethical approach therefore comprises three essential stages: recognizing the event as such, informing those involved of the event and, finally, creating conditions for the continuation of care. Each of these stages is marked by specific issues and questions, requiring a complex ethical approach that constantly involves reconciling the possible divergent perceptions of patients and health professionals. The occurrence of an event can also lead to a genuine crisis of confidence with multiple dimensions, which health professionals will also have to face and to support. Finally, the occurrence of an event calls into question not only our responsibility towards patients, but also our ideal of control. We need to criticize our culture of performance, rethink our approach to events and errors, and see them also as opportunities for positive change.
