BACKGROUND Total hip joint replacement (THR) is a high volume, effective intervention for hip osteoarthritis (OA). However, indications and determinants of outcome remain unclear. The 'EUROHIP consortium' has undertaken a cohort study to investigate these questions. This paper describes the variations in disease severity in this cohort and the relationships(More)
We validated the North American Spine Society (NASS) outcome-assessment instrument for the lumbar spine in a computerised touch-screen format and assessed patients' acceptance, taking into account previous computer experience, age and gender. Fifty consecutive patients with symptomatic and radiologically-proven degenerative disease of the lumbar spine(More)
BACKGROUND The Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index is a previously described self-administered questionnaire covering three domains: pain, stiffness and function. It has been validated in patients with osteoarthritis (OA) of the hip or knee in a paper-based format. AIM To validate the WOMAC 3.0 using a numerical rating(More)
AIM The aim of this study was to determine the outcome after total hip replacement (THR) with the WOMAC and the SF-36 as well as to identify the most responsive items and to elucidate the reasons for increased pain postoperatively. METHODS 73 patients filled out the questionnaires preoperatively and 3, 6, 12, 24 months postoperatively. All mean subscales(More)
BACKGROUND The precision of symptom assessment and documentation in daily routine is unknown. Differences in hip studies have been observed between the charts and the patient questionnaires. This was the reason to perform this study and to compare the charts and the patient questionnaires. METHODS This was a retrospective study of physician versus patient(More)
BACKGROUND The outcome of orthopaedic surgery such as total hip replacement (THR) or total knee replacement (TKR) is commonly given by the change in mean scores on patient-reported outcome measures (Prom's). This may give the impression that all enrolled patients have experienced an improvement. But the Swedish hip registry and other studies report a(More)
OBJECTIVE To validate a new method to identify responders (relative effect per patient (REPP) >0.2) using the OMERACT-OARSI criteria as gold standard in a large multicentre sample. METHOD The REPP ([score before - after treatment]/score before treatment) was calculated for 845 patients of a large multicenter European cohort study for THR. The patients(More)
AIM The aim of this study was to measure musculoskeletal symptoms and disabilities in a structured and objective manner. For this purpose, we have developed a simple patient questionnaire (Pationnaire). This includes the most important symptoms and signs of the entire musculoskeletal system including the vertebrae. METHODS The questionnaire was tested for(More)
BACKGROUND Review of medical records demonstrates a moderate to low correlation (r = 0.57 to 0.22) between daily limitations and symptoms based upon patient history. This correlation could be improved with the ideal questionnaire which would assess patients using the same questions with the same response options in the same order. Therefore, a simple(More)
AIM The visual analogue scale (VAS) and Likert scale (LS) are widely used but the patients might have difficulties to work with these scales and there might be errors in calculation. The visual circle scale (VCS) is a graphic construct with a simple grading to augment the understanding and ease for calculation. METHOD This study compares the different(More)
