Developing multi-perspective practice-based evidence theses for breaking bad news in the German pediatric oncology: A participatory group Delphi study

To our knowledge, no prior research in pediatric oncology has systematically integrated existing PBE into a structured set of recommendations in Germany. This study introduces a novel PGD process in this field in Germany, incorporating three key innovations: (1) a participatory methodology ensuring active stakeholder engagement, (2) a uniquely diverse expert panel including those affected by pediatric cancer, and (3) a systematic, iterative recommendation development approach rooted in PBE. This methodology results in a Delphi process that diverges significantly from classical approaches, offering a collaborative and structured framework for evidence synthesis.
