The work of developing clinical guidelines for best practices within the RTT workflow in proton therapy is about to start. The 6^th to 7^th of February the TaSeRnet project group and a member of the ESTRO guideline commitee will meet in Denmark to discuss and decide upon the process of guideline development, publication and implementation. The guidelines will be founded on both the scoping review and the results of the Delphi Study conducted in work package 2 in the TaSeRnet project.

The Delphi consensus study aimed at establishing best practices for RTTs and dosimetrists has successfully concluded after three rounds of in-depth expert input. The study, which involved a group of 40 RTTs and dosimetrists from 10 proton centers across Europe, has resulted in consensus on 24 out of 26 statements about workflow steps in which RTTs and dosimetrist play a key role. The collaborative effort was designed to identify best practices, relying on the expertise and insights of participants to guide the final outcomes. Through the structured Delphi method, experts were able to anonymously vote on proposed workflow steps, gradually converging on a set of recommendations. In addition to establishing best practices, the outcomes of this Delphi study will play a key role in the development of comprehensive guidelines for workflow steps (WP3). These guidelines, based on the consensus reached in the study, are expected to help standardize practices and enhance quality in proton therapy. 

The next step is to formally publish the findings, and we are currently working on preparing the results for publication in a peer-reviewed journal. Once the article is released, all participants in the study will be notified so they can access the final, peer-reviewed document. With 24 of the 26 steps receiving agreement, the study provides a robust framework that can help standardize and optimize workflows in proton therapy. 

We'd like to thank everyone who contributed to this study, as their insights and expertise played a key role in forming the final conclusions!

This week, we initiated a Delphi consensus process aimed at establishing best practices for RTTs and dosimetrists. Over the past few months, our team has worked hard to analyze the outcomes of the TaSeRnet workshop and complete a scoping review of existing literature related to RTT guidelines.
Based on this work, we have developed 26 statements to guide the Delphi process. After a thorough review by our steering committee and the workshop secretaries, these statements are now ready for distribution to our voting panel. We are proud to have representation from 10 countries, making this a truly European consensus effort.
We anticipate completing three rounds of the Delphi process, with final results collected by the end of November. The outcomes will be published and used to develop comprehensive guidelines for RTTs and dosimetrists.
