The Working Group on Patient Safety and Quality of the Spanish Society of Radiation Oncology, revised the most relevant national and international recommendations, selecting a series of important aspects for patient safety, evaluating whether they are included in Spanish legislation MATERIALS AND METHODS: We have considered a concept as relevant to the patient safety in radiotherapy if so defined in at least 8 of the 16 documents reviewed.12 subjects were selected: training and qualification, human resources, protocols, safety culture, communication, peer review, accreditation: audits, checklists, areas without interruptions, maps of processes and risks, prospective risk analysis, notification, registration and incident learning, and quality control of the equipment.At the legislative level, as well as the professional organizations and the health center directorates, the implementation of safety culture must continue to be fostered. Only in this environment will the tools and measures to increase patient safety be effective. The current Spanish legislation must be revised and updated, in accordance with directive 2013/59/EURATOM and the Patient Safety Strategy 2015-2020 of the Spanish National Health System, introducing the obligation to perform risk analysis and incidents management. Audits and accreditations must be carried out, thus raising the general level of practice of the specialty. In this process, the Spanish Society of Radiation Oncology must continue playing its fundamental role, collaborating with the institutions and the rest of the scientific societies involved in the radiotherapy process, issuing recommendations on patient safety and disseminating the safety culture in our specialty.
