The NHS Outcomes Framework 2011/12 from the Department of Health states that reducing health inequalities and promoting equality is central if the NHS is to deliver health outcomes that are among the best in the world. Assessment of patient reported outcome measures (PROMS) was introduced across the NHS in April 2009 both for hip and knee replacement surgery. PROMs are applied before and after certain elective health interventions funded by the NHS. In addition to the established use in assessment of outcomes, it has been suggested that preoperative instruments might be used to assess whether referrals for elective procedures are appropriate and also to identify inequalities in heathcare. For hip and knee replacement surgery, Oxford hip and knee scores are used as the measure of pain and disability.

Abstract Background The degree to which a validated instrument is able to detect clinically significant change over time is an important issue for the better management of hip or knee replacement surgery. This study examines the internal responsiveness of the EQ-5D-3L, the Oxford Hip Score (OHS), and the Oxford Knee Score (OKS) by various methods. Data from NHS patient-reported outcome measures (PROMs) linked to the Hospital Episodes Statistics (HES) dataset (2009–2015) was analysed for patients who underwent primary hip surgery (N = 181,424) and primary knee surgery (N = 191,379). Methods Paired data-specific univariate responsiveness was investigated using the standardized response mean (SRM), the standardized effect size (SES), and the responsiveness index (RI). Multivariate responsiveness was furthermore examined using the defined capacity of benefit score (i.e. paired data-specific MCID), adjusting baseline covariates such as age, gender, and comorbidities in the Box-Cox regression models. The observed and predicted percentages of patient improvement were examined both as a whole and by the patients' self-assessed transition level. Results The results showed that both the OHS and the OKS demonstrated great univariate and multivariate responsiveness. The percentages of the observed (predicted) total improvement were high: 51 (54)% in the OHS and 73 (58)% in OKS. The OHS and the OKS showed distinctive differences in improvement by the 3-level transition, i.e. a little better vs. about the same vs. a little worse. The univariate responsiveness of the EQ-5D-3L showed moderate effects in total by Cohen’s thresholds. The percentages of improvement in the EQ-5D-3L were moderate: 44 (48)% in the hip and 42 (44)% for the knee replacement population. Conclusions Distinctive percentage differences in patients’ perception of improvement were observed when the paired data-specific capacity of benefit score was applied to examine responsiveness. This is useful in clinical practice as rationale for access to surgery at the individual-patient level. This study shows the importance of analytic methods and instruments for investigation of the health status in hip and/or knee replacement surgery. The study finding also supports the idea of using a generic measure along with the disease-specific instruments in terms of cross-validation.

Abstract Background Competition-promoting reforms and economic incentives are increasingly being introduced worldwide to improve the performance of healthcare delivery. This study considers such a reform which was initiated in 2009 for elective hip replacement surgery in Stockholm, Sweden. The reform involved patient choice of provider, free establishment of new providers and a bundled payment model. The study aimed to examine its effects on hip replacement surgery quality as captured by patient reported outcome measures (PROMs) of health gain (as indicated by the EQ-5D index and a visual analogue scale (VAS)), pain reduction (VAS) and patient satisfaction (VAS) one and six years after the surgery. Methods Using patient-level data collected from multiple national registers, we applied a quasi-experimental research design. Data were collected for elective primary total hip replacements that were carried out between 2008 and 2012, and contain information on patient demography, the surgery and PROMs at baseline and at one- and six-years follow-up. In total, 36,627 observations were included in the analysis. First, entropy balancing was applied in order to reduce differences in observable characteristics between treatment groups. Second, difference-in-difference analyses were conducted to eliminate unobserved time-invariant differences between treatment groups and to estimate the causal treatment effects. Results The entropy balancing was successful in creating balance in all covariates between treatment groups. No significant effects of the reform were found on any of the included PROMs at one- and six-years follow-up. The sensitivity analyses showed that the results were robust. Conclusions Competition and bundled payment had no effects on the quality of hip replacement surgery as captured by post-surgery PROMs of health gain, pain reduction and patient satisfaction. The study provides important insights to the limited knowledge on the effects of competition and economic incentives on PROMs.

Abstract Background The Catquest-9SF questionnaire is a patient reported outcome measure that quantifies the visual benefits from cataract surgery. The purpose of this study was to translate and adapt the Catquest-9SF questionnaire for France, to assess its psychometric properties via Rasch analysis, and to assess its validity when completed using an electronic notepad. Methods The Catquest-9SF questionnaire was translated following the guidelines of the International Society for Pharmacoeconomics and Outcomes Research. Catquest-9SF and clinical data were collected from patients before and after routine cataract surgery. All questionnaire data were collected via an electronic notepad. Rasch analysis was performed to assess psychometric properties, and sensitivity to change was analysed for patients with complete paired pre- and post-operative questionnaires. Results A complete filled-in preoperative questionnaire was obtained for 848 patients. Rasch analysis showed good precision (person separation: 2.32, person reliability: 0.84), ordered category probability curves, no item misfit, and unidimensionality. The respondents were slightly more able than the level of item difficulty (targeting: −1.12 logits). Sensitivity was analysed on 211 paired questionnaires, and the postoperative questionnaires showed a clear ceiling effect. The effect size was 2.6. The use of an electronic notepad for completing the questionnaire worked out very well after some adjustments. Conclusions The French version of Catquest-9SF has good psychometric properties and is suitable for use in French-speaking patients. The use of the Catquest-9SF questionnaire in an electronic format showed good validity.

Australian Experience

The Australian Orthopaedic Association National Joint Replacement Registry first began data collection on 1 September 1999 and full nationwide implementation commenced in January 2003. The purpose of the Registry is to improve the quality of care for individuals receiving joint replacement surgery. The Registry enables surgeons, academic institutions, governments and industry to request specific data that are not available in published annual reports. There is an established system for identifying prostheses with a higher than anticipated rate of revision (HTARR) which was introduced in 2004. The higher rate of revision for the ASR Hip Resurfacing System was first identified by this process in 2007. There has been a reduction in revision hip and knee replacement over the years that the Registry has been in operation, and the addition of Patient Reported Outcome Measures (PROMs) and data linkage will enable more extensive analysis of joint replacement surgery in the future.

Introduction NHS England uses the Oxford Knee Score (OKS) as part of patient-reported outcome measures (PROMs) to evaluate ‘health gains’ following total knee replacement. Policy makers use this to guide healthcare funding and resource allocation. Our study aims to undertake a qualitative and quantitative analysis of OKS among patients who experienced a negative outcome after a total knee replacement at our centre. Materials and methods Between April 2017-March 2018, 19 of 189 (10%) patients had a worsened OKS at our centre. We retrospectively and prospectively reviewed 14 of these patients. Structured telephone interviews with a repeat OKS were carried out in September 2019 (18–29 months post-operation). Results Eight patients were female and the total age range was 57–95, mean average 75.6 (SD 9.9 years). Of 48 (higher scores meaning better outcomes), the average preoperative OKS was 24.2 and the average postoperative OKS at 6 months was 19.4 (decrease of 20%). The average postoperative OKS at 18–29 months was 35.6 (an increase of 83.5% from 6 months). Discussion The OKS was developed and validated over 20 years ago in Oxford. In our study, four patients asked for clarification of questions 4, 6 and 10 owing to ambiguous language. All 14 patients who had negative OKS outcomes had positive outcomes when retested after 18 months, depicting ‘health gains’ not conveyed in PROMs analysis. Conclusion The OKS needs to be revalidated on current patient groups for accurate and reliable data. Further prospective studies should be undertaken on larger cohorts to understand the recovery course and whether PROMs should be carried out later.
