Current clinical practice in bariatric surgery follow-up care is highly heterogeneous, and patients have reported needing more and extended personalised support. Especially, they want more support on how to self-manage and cope with the changes and challenges of living with the chronic aspects of obesity and a changing body following surgery. The overall aim of this study protocol is to develop and validate a digital self-management support checklist in bariatric surgery aftercare.

We propose a protocol for a modified, electronic Delphi study design using qualitative and quantitative methods to develop and validate the content of the checklist. The study is divided into two phases: (1) generation of candidate checklist attributes and (2) validation of candidate checklist attributes. In Phase 1, two qualitative studies involving individual interviews with patients and focus groups with healthcare professionals will be conducted to derive context-specific knowledge. This knowledge will be combined with best-practice evidence and stakeholder input to generate candidate checklist attributes, that is, principles, items and features. In Phase 2, a two-round electronic Delphi survey with an expert panel will be conducted to assess the relevance, comprehensibility and comprehensiveness of candidate checklist attributes and to determine the final checklist attributes based on content validity results from the Delphi process. Reflexive thematic analysis will be used on qualitative data and descriptive statistics on quantitative data.

The study has been approved by the Regional Committee for Medical and Health Research Ethics, Region West (2023/676367). The Data Protection Officer at Førde Hospital Trust and collaborating hospital trusts have approved the project (4386–4386). The results will be presented at scientific conferences, published and open-accessed in international peer-reviewed journals.
