OpenApp is delighted to report that it has received Developer Approved Status for the online versions of the Oxford Hip and Knee Score. This is essential for use in arthroplasty registries.

This was awarded to OpenApp by Isis Outcomes, a department of Isis Innovation. Isis Outcomes are specialists in Patient Reported Outcome Measures (PROMS) and are a leader in technology transfer, having recently won the 'Technology Transfer Unit of the Year' beating off stiff competition by Cambridge and Stanford at the Global University Venturing Awards.

The Oxford Knee Score (OKS) and Oxford Hip Score (OHS) are 12-item patient-reported PROs specifically designed and developed to assess function and pain after total knee replacement (TKR) surgery (arthroplasty) and those undergoing hip replacement surgery. It is short, reproducible, valid and sensitive to clinically important changes.

The OKS and OHS is the most evaluated hip specific measure available.

Prior to the development of the OHS and OKS, only crude measures of surgical failure, such as the need to perform revision surgery, had been employed in the assessment of patient outcomes. The development of the OHS was driven by the need to conduct more systematic and accurate monitoring of patient outcomes following THR.

Similar to the situation with hip replacement, prior to the development of the OKS, only crude measures of surgical failure such as the need to perform revision surgery had been employed in the assessment of patient outcomes. The development of the OKS was driven by the need to conduct more systematic and accurate monitoring of patient outcomes following TKR. As a relatively short instrument the OKS is particularly appropriate for use by older individuals who most often receive TKR.

Details of the development protocol and scoring system for the OKS are described in: Dawson J, Fitzpatrick R, Carr A, Murray D. Questionnaire on the perceptions of patients about total hip replacement J Bone Joint Surg Br. 1998 Jan;80(1):63-69

OpenApp have now incorporated the OHS and OKS into their eHealth Clinical Insight Platform and Arthroplasty Registry software.
