Uptake of the OMERACT-OARSI Hip and Knee Osteoarthritis Core Outcome Set: review of randomized controlled trials from 1997 to 2017 Academic Article uri icon


  • Objective.To assess the uptake of the OMERACT-OARSI (Outcome Measures in Rheumatology- Osteoarthritis Research Society International) core outcome set (COS) domains in hip and/or knee osteoarthritis (OA) trials.Methods.There were 382 trials of hip and/or knee OA identified from the ClinicalTrial.gov registry from 1997 to 2017. Frequency of COS adoption was assessed by year and per 5-yearly phases.Results.COS adoption decreased from 61% between 1997 and 2001 to 38% between 2012 and 2016. Pain (95%) and physical function (86%) were most consistently adopted. Patient’s global assessment (48%) was the principal missing domain.Conclusion.Limited adoption of the COS domains indicates that further consideration to improve uptake is required.
