At the ESTRO Congress 2025 in Vienna, the ESTRO ROSQ Committee (Radiation Oncology Safety and Quality) proudly launched the Radiation Oncology Safety Education and Information System, or ROSEIS.
Radiotherapy incidents, although rare, can have serious consequences. Yet too often, valuable information remains isolated within individual departments, missing opportunities to learn and prevent injury to future patients. ROSEIS was developed to change that by creating a shared, proactive space for safety learning and quality improvement across the radiotherapy community.
Why was ROSEIS created?
ROSEIS was created to enable the sharing of information on incidents and near incidents in a safe environment to increase learning and improve the quality and safety of practice across European centres.
The EU Directive 2013/59/EURATOM mandates that radiotherapy centres implement a reporting and learning system for incidents, and the ESTRO ROSEIS enables centres without an existing reporting system to comply with this directive by providing a platform for reporting, reviewing, and anonymously sharing safety data across the radiotherapy community.
What ROSEIS offers
An effective reporting and learning system increases the safety profile of radiotherapy, raises safety awareness among healthcare professionals, and reassures patients and the public that radiotherapy actively works to improve the safety and quality of its practice.
Precisely, it offers:
- A platform for reporting and learning from incidents in radiotherapy.
- Anonymous data sharing to help institutions learn from one another, fostering continuous improvement.
- A searchable incident database, promoting open access to past cases and lessons learned.
- Additional resources, including:
- A curated list of publications.
- Lectures on safety legislation.
- A dedicated webinar series exploring the foundations of safe practice from both patient and staff perspectives.
