Safety and efficacy of flow-diverter stents in endovascular treatment of intracranial aneurysm: Interest of the prospective DIVERSION observational study

摘要

Background: The German Society of Radiation Oncology (DEGRO) initiated a multicenter trial to develop and evaluate adequate modules to assert core procedures in radiotherapy. The aim of this prospective evaluation was to methodical assess the required resources for radiotherapy in pediatric and adolescent patients. Material and methods: At three radiotherapy centers of excellence (University Hospitals of Heidelberg and Münster, the Medical School of Hannover), the manpower and time required for radiotherapy in pediatric and adolescent patients was prospectively documented consistently over a 2-year period. The data were collected using specifically developed standard forms and were evaluated using specific process analysis tools. Results: A total number of 1914 data sets were documented and carefully analyzed. The personnel time requirements for all occupational groups were calculated as total time needed for a specific procedure and mean time per person. Regarding radiotherapy in general anesthesia, the required manpower was higher. The personnel time requirements in these cases were also longer, mainly due to longer room occupancy. Overall, the required resources were remarkably similar between the three different departments and may, therefore, be considered as representative. Conclusion: For the first time, the personnel time requirements of a radiotherapy department for the maintenance, protection, and optimization of operational readiness for radiotherapy in pediatric and adolescent patients with and without general anesthesia were determined methodically.
