The project will use a modified Delphi approach because the available evidence is too heterogeneous for recommendations based only on empirical data. A 75% essential-rating threshold identifies principles that are widely valued and should be prioritised. The modified Delphi method is intended to provide a structured, iterative process for refining recommendations while preserving anonymous feedback.

Anonymous structured feedback was used to focus panel deliberations on controversial criteria. The study used a two-round modified Delphi panel conducted from September through December 2024. The Delphi rounds will use independent anonymous ratings on a five-point Likert scale. Round 2 re-ratings after discussion determined the final episode criteria. A statement will be considered to have reached consensus when at least 80% of panelists rate it as agree or strongly agree. Final code retention required both validity and absence of predefined disagreement in round 2. A virtual modified Delphi process will be conducted in summer 2026 with academic,…
