Evaluation of patients' engagement in radiation therapy safety.

Purpose: Treatment safety has become a priority in health policies after several incidents occurred around the world in radiation oncology departments. The aim of this study was to analyse the patients' contribution in that field and to understand which actions empower the patient in that regard.

Methods: Several methods were used in a general hospital and in a comprehensive cancer centre to analyse the activities of the radiation therapists and the patients and the interactions between them: treatment session observations, semidirective interviews with radiation therapists and patients, self and alloconfrontation with radiation therapists and explanatory interviews with patients.

Results: Cooperation of the patients in treatment safety acts as an additional step that contributes to safer treatments. Radiation therapy sessions are a creative opportunity for the patient to observe, learn and analyse what is happening. Changes between treatment sessions are a source of anxiety for the patients. This study highlights the factors that favour the patients' participation. A trusting relationship and support from the health professionals can be leveraged in that manner.

Conclusion: There is a common will shared between the patients and the health professionals towards better treatment safety. The cooperation is still not well-known and underused. This empowerment of the patient cannot be mandatory but should be promoted and developed.
