Abstract
Objective To achieve consensus on the most important outcome domains to measure across all clinical trials for shoulder disorders.
Methods We performed an online modified Delphi study with an international, multidisciplinary and multistakeholder panel. A literature review and the OMERACT Filter 2.0 framework was used to generate a list of potential core domains, which were presented to patients, clinicians and researchers in two Delphi rounds. Participants were asked to judge the importance of each potential core domain and provide a rationale for their response. A core domain was defined a priori as a domain that at least 67% of participants considered core.
Results In both rounds, 335 individuals were invited to participate (268 clinicians/researchers and 67 patients); response rates were 27% (n=91) and 29% (n=96), respectively. From a list of 41 potential core domains, four domains met our criteria for inclusion: ‘pain’, ‘physical functioning’, ‘global assessment of treatment success’ and ‘health-related quality of life’. Two additional domains, ‘sleep functioning’ and ‘psychological functioning’, met the criteria for inclusion by some, but not all stakeholder groups. There was consensus that ‘number of deaths’ was not a core domain, but insufficient agreement on whether or not several other domains, including ‘range of motion’ and ‘muscle strength’, were core domains.
Conclusions Based on international consensus from patients, clinicians and researchers, ‘pain’, ‘physical functioning’, ‘global assessment of treatment success’ and ‘health-related quality of life’ were considered core outcome domains for shoulder disorder trials. The value of several other domains needs further consideration.
