Background: Outcome evaluation in people with hand and wrist scars is not standardised. To improve clinical care and research rigour, the authors are developing a core outcome set (COS) for the evaluation of hand scars. This survey identified what international clinicians and academics consider important outcomes for inclusion when evaluating people with hand scarring. Methods: An electronic survey was developed, peer reviewed and disseminated via professional networks and social media. Professionals of diverse clinical backgrounds and geographical location with experience in the evaluation of hand and wrist scar outcomes in adults were invited to participate. The survey opened in February and closed in May 2022. Results: 162 participants, representing all World Health Organisation geographical regions, completed the survey. 32% of respondents reported using standardised scar patient reported outcome measures (PROMs); 31% using standardised scar clinician reported outcome measures (CROMs). In assessing physical symptoms of scar, sensitivity/hypersensitivity received the highest importance rating, and 36 additional physical symptom constructs were added as free text items by 72 participants. Regarding physical characteristic of scar, evaluation of adhesions was rated as most important and 19 additional physical characteristics were reported by 21 participants. Active range of motion was rated the most important impairment evaluation. In the domain of psychological impact of scarring, satisfaction with scarring and appearance acceptability were rated equally important. Sixty percent of participants reported using a standardised patient-reported outcome measure (PROM) for evaluating the functional impact of scars in the hand and wrist. Discussion: This survey identified items for inclusion in the first round of a stakeholder Delphi consensus study, to agree a COS for the evaluation of hand and wrist scars. Frequency of importance ratings for evaluation constructs were determined to gauge the priorities of survey participants, not to exclude constructs. The disparate outcomes reported by free text within outcome domains highlights the lack of an agreed scar evaluation taxonomy, an important consideration for future consensus work. 107 (66%) of survey respondents consented to contact regarding further scar outcome evaluation consensus work, highlighting this work as a clinical priority.

I confirm all relevant ethical guidelines have been followed, and any necessary IRB and/or ethics committee approvals have been obtained.

Yes

I confirm that all necessary patient/participant consent has been obtained and the appropriate institutional forms have been archived, and that any patient/participant/sample identifiers included were not known to anyone (e.g., hospital staff, patients or participants themselves) outside the research group so cannot be used to identify individuals.

Yes

I understand that all clinical trials and any other prospective interventional studies must be registered with an ICMJE-approved registry, such as ClinicalTrials.gov. I confirm that any such study reported in the manuscript has been registered and the trial registration ID is provided (note: if posting a prospective study registered retrospectively, please provide a statement in the trial ID field explaining why the study was not registered in advance).

Yes

I have followed all appropriate research reporting guidelines, such as any relevant EQUATOR Network research reporting checklist(s) and other pertinent material, if applicable.
