National consensus to develop core outcomes for the evaluation of complications from excess weight (CEW) clinics: results of a national Delphi process.

Objective: In 2021, centres across all seven NHS-England regions were selected to develop pilot clinics with the aim of treating children and young people (CYP) living with complications relating to excess weight (CEW). We led a process to develop core outcomes to enable the evaluation of these clinics.

Methods: A two-round Delphi process, virtual steering group meetings and two patient representation workshops were used to agree the most important outcomes for both clinicians/allied professionals and representative prospective service users.
