Background/Purpose: To define a minimum Standard Set of outcome measures and case-mix factors for monitoring, comparing, and improving healthcare for patients with clinically diagnosed hip or knee osteoarthritis (OA) with a focus on defining the outcomes that matter most to patients.

Methods:  An international Working Group (WG) of patients, arthroplasty register experts, orthopedic surgeons, primary care physicians, rheumatologists, and physical therapists representing 10 countries was assembled to review existing literature and practices for assessing outcomes of pharmacological and non-pharmacological OA therapies including surgery. A series of 8 teleconferences, incorporating a modified Delphi process, were held to reach consensus.

Results: The WG reached consensus on a concise set of outcomes measures to evaluate patients’ joint pain, physical functioning, health-related quality of life, work status, mortality, reoperations, readmissions, and overall satisfaction with treatment result. To support analysis of these outcome measures, pertinent baseline characteristics and risk factor metrics were defined (see Table 1). Annual outcome measurement is recommended for all patients.

Conclusion: We have defined a Standard Set of outcome measures for monitoring the care of people with clinically diagnosed hip and knee OA that is appropriate for use across in all treatment and care settings. We believe this Standard Set provides meaningful, comparable, and easy to interpret measures ready to implement in clinics and/or registries globally. We view this as an initial step that, when combined with cost data, will facilitate value-based healthcare improvements in the treatment of hip and knee OA.
