246 · DOS Abstracts Patient involvement in evaluation of the Oxford Hip Score – based on preoperative and postoperative interviews of patients undergoing total hip arthroplasty Camilla Holmenlund, Søren Overgaard, Randi Bilberg, Claus Varnum Department of Orthopaedic Surgery and Traumatology, Odense University Hospital ; Department of Orthopaedic Surgery and Traumatology, Odense University Hospital , Institute of Clinical Research, Faculty of Health Sciences, University of Southern Denmark; Department of Clinical Research, Unit of Clinical Alcohol Research, University of Southern Denmark; Department of Orthopaedic Surgery, Section for Hip and Knee Replacement, Vejle Hospital Background: The Oxford Hip Score (OHS) is often used when evaluating the outcome after total hip arthroplasty (THA). The OHS was developed more than twenty years ago with some degree of patient involvement. We speculate if the OHS is still relevant for the patients before and after THA. Purpose / Aim of Study: The aim of this study was through focus group in- terviews to determine if the OHS contains the items that today’s patients find relevant pre-op., and at 3 and 12 months post-op. Materials and Methods: Patients aged 60-75 years with primary osteoarthri- tis receiving THA were recruited from OUH and Vejle Hospital for focus group interviews pre-op. and at 3 and 12 months post-op. Six focus group interviews were conducted totaling 30 patients of whom two were excluded in the data analysis, as they did not fulfill the inclusion criteria. The interviews were audio- recorded and transcribed verbatim. Interview transcripts were inductively orga- nized into categories using thematic analysis. Findings / Results: When comparing categories identified from the interviews to the items of OHS, we found that items such as pain and walking were very im- portant to all three groups of patients. Items such as limping was only important pre-op and 3 months post-op. and not mentioned at 12 months. Furthermore, we identified several categories that the OHS does not cover, including cycling, the ability to get on the floor, sport and quality of life, that were found to be very important to the patients pre-op. and post-op. Conclusions: We showed that the OHS lacks several dimensions according to the patients. Our study suggests that other patient-reported outcome mea- sures (PROMs) than the OHS should be used when evaluating the outcome of THA. It may indicate a need for a new PROM to evaluate the outcome for these patients. 187.
