The oracle of D-A-Ch - Results of a Delphi Survey for the development of the evidence- and consensus-based tool "My Logbook".

Objective: The present report describes the results of four delphi surveys conducted within the quality improvement project "My Logbook" which aims to translate evidence-based standards for psychosocial care in pediatric oncology into a practical consensus-based tool.

Methods: In four consecutive delphi surveys a total of n=153 international, multi-disciplinary experts rated the content, method, and design of the different booklets of "My Logbook" which a local expert group had conceptualized. After each survey, the feedback was incorporated, and the changes were evaluated in a final consensus vote by the quality assurance panel of the PSAPOH.

Results: While some surveys led to a review on a page level, most booklets as a whole reached the consensus-level of approval. Over the course of the surveys, any revisions and comments were incorporated in the booklets, and approval rates increased steadily.

Discussion: The delphi surveys ensured the integration of multi-disciplinary, international expertise, uncovering issues such as language barriers and the need for a user manual that would not have been evident in first line . The incorporation of the input led to a continuous improvement of the tool, reflected in steadily increasing acceptance rates in the consecutive survey rounds.

Conclusion: The incorporation of the expert input as well as the additional development of a user manual resulted in a final version of the "My Logbook" apt for the interdisciplinary application in pediatric oncology in the entire DACH-region.
