Dave U, Lewis EG, Patel JH, Godbole N. Private health insurance in the United States and Sweden: A comparative review. Health Sci Rep 2024; 7:e1979. [PMID: 38495896 PMCID: PMC10940498 DOI: 10.1002/hsr2.1979] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2023] [Revised: 01/27/2024] [Accepted: 02/28/2024] [Indexed: 03/19/2024] Open
Abstract
Background and Aims The United States of America and Sweden both contain a public and private component to their healthcare systems. While both countries spend a similar amount per capita on public healthcare expenditures, the United States spends significantly more in the private healthcare sector. Sweden has a social democratic model of health care, and given its identity as a welfare state, private health insurance providers have a small and nuanced role. Methods This paper was completed after searches were queried for "Sweden," "United States," and variants of the words "insurance," "public," "private," "Medicare," "Medicaid," "public," and "costs." A preliminary search in May 2022, yielded 78 articles, of which 45 were ultimately considered relevant for this review. Inclusion criteria consisted of English language articles, topic relevance, and verification of MEDLINE-indexed journals. These searches were performed in PubMed, Google Scholar, Embase, and Cochrane. Summary findings of these searches are compiled in this review. Results Sweden guarantees low-cost appropriate care to all citizens with equitable access; however, drawbacks of its system include high financial burden, lack of primary care infrastructure, as well as geographical and socioeconomic inequities. On the other hand, the United States' healthcare system is built around the private sector with public health insurance reserved only for the most vulnerable patient populations. Conclusion Our goal is to provide an overview, compare the role of private health insurance in both countries, and highlight policies that have had beneficial effects in each nation. Possible solutions to the drawbacks of each nation's health insurance policies could be addressed by additional support to Sweden's vulnerable population by developing a program similar to the US' Medicare Advantage program. Conversely, the United States may benefit from increasing access to public health insurance, especially in instances where families face unemployment.

J Arthroplasty 2023; 38:1652-1657. [PMID: 36963532 DOI: 10.1016/j.arth.2023.03.050] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/25/2022] [Revised: 03/13/2023] [Accepted: 03/16/2023] [Indexed: 03/26/2023] Open
Abstract
BACKGROUND Few studies have assessed how socioeconomic status (SES) influences patient-reported outcomes (PROMs) after total knee arthroplasty (TKA). This study evaluated the impact of patient median ZIP code income levels on PROMs after TKA. METHODS We retrospectively reviewed patients at our institution undergoing primary, unilateral TKA from 2017 to 2020. Patients who did not have one-year postoperative PROMs were excluded. Patients were stratified based on the quartile of their home ZIP code median income from United States Census Bureau data. There were 1,267 patients included: 98 in quartile 1 (median income ≤ $46,308) (7.7%); 126 in quartile 2 (median income $46,309-$57,848) (10.0%); 194 in quartile 3 (median income $57,849-$74,011) (15.7%); and 849 in quartile 4 (median income ≥ $74,012) (66.4%). We collected baseline demographic data, 2-year outcomes, and PROMs preoperatively, as well as at 12 weeks and one year, postoperatively. RESULTS The Knee Injury and Osteoarthritis Outcome Score for Joint Replacement was significantly higher in quartile 4 preoperatively (P < .001), 12 weeks postoperatively (P < .001), and one year postoperatively (P < .001). There were no significant differences in delta improvements of Knee Injury and Osteoarthritis Outcome Score for Joint Replacement from preoperative to 12 weeks or one year postoperatively. There were no significant differences in lengths of stay, discharge dispositions, readmissions, or revisions. CONCLUSION Patients from lower income areas have slightly worse knee function preoperatively and worse outcomes following TKA. However, improvements in PROMs throughout the first year postoperatively are similar across income quartiles, suggesting that patients from lower income quartiles achieve comparable therapeutic benefits from TKA. LEVEL III EVIDENCE Retrospective Cohort Study.

Abstract
Aims To determine whether there was a relation between socioeconomic status (SES) and patient symptoms before and one year after total knee arthroplasty (TKA), and/or total hip arthroplasty (THA) and whether a change in symptoms was clinically relevant. Patients and methods A secondary analysis of a prospective cohort study was conducted on SES and osteoarthritis symptoms of patients (≥45 years old) who received a primary TKA or THA between 2016 and 2018. The relation between SES and respectively pre- and postoperative and change in patient-reported outcome measures including the Oxford Knee Score (OKS), Oxford Hip Score (OHS), Western Ontario and McMaster Universities Arthritis Index (WOMAC), the visual analog scale (VAS) for pain and the EuroQol 5-Dimensions (EQ-5D) were assessed using linear mixed-effects regression models adjusted for age and sex. The following potential confounding variables were considered in the regression models: body mass index (BMI), American Society of Anesthesiologists (ASA)- classification, Charnley-classification, smoking status, and alcohol consumption. Results Patients with lower SES were mostly female, had a higher BMI and ASA-classification compared to patients with a higher SES. Patients with lower SES reported lower OKS (β = 3.78, P = 0.001). Patients undergoing THA reported lower scores for the OHS (β = 4.78, P = 0.001), WOMAC (β = 11.7, P = 0.001), and less pain (VAS, β = -0.91, P = 0.001). No statistically significant differences between SES groups were seen in the quality of life and health status as measured with the EQ-5D. Conclusion Patients with a lower socioeconomic status reported worse symptoms and showed less clinically relevant improvement at one-year follow-up.

Abstract
OBJECTIVE To assess criteria and psychometric properties of instruments for assessing appropriateness of elective joint arthroplasty (JA) for adults with primary hip and knee osteoarthritis (OA). METHODS A systematic review guided by Cochrane methods and PRISMA guidelines. Studies were searched in five databases. Eligible articles include all study designs developing, testing, and/or using an instrument to assess JA appropriateness. Two independent reviewers screened and extracted data. Instruments were compared with Hawker et al. JA consensus criteria. Psychometric properties of instruments were described and appraised guided by Fitzpatrick's and COSMIN approaches. RESULTS Of 55 instruments included, none met all Hawker et al. JA consensus criteria. Criteria the most met were pain (n = 50), function (n = 49), quality of life (n = 33), and radiography (n = 24). Criteria the least met were clinical evidence of OA (n = 18), expectations (n = 15), readiness for surgery (n = 11), conservative treatments (n = 8), and patient/surgeon agree benefits outweigh risks (n = 0). Instrument by Arden et al. met the most criteria (6 of 9). The most tested psychometric properties were appropriateness (n = 55), face/content validity (n = 55), predictive validity (n = 29), construct validity and feasibility (n = 24). The least tested psychometric properties were intra-rater reliability (n = 3), internal consistency (n = 5), and inter-rater reliability (n = 13). Instruments by Gutacker et al. and Osborne et al. met the most psychometric properties (4 of 10). CONCLUSION Most instruments included traditional criteria for assessing JA appropriateness but did not include a trial of conservative treatments or shared decision-making elements. There was limited evidence on psychometric properties.

Abstract
BACKGROUND Disease burden in patients prior to total knee arthroplasty (TKA) varies widely between studies and countries. We aimed to characterize individuals undergoing TKA and examine their expectations from the surgery, focusing on variations in disease burden. METHODS Consecutive patients undergoing primary TKA in a German university hospital were recruited. A questionnaire including information on disease burden, preoperative expectations from surgery, health care utilization, demography, and socioeconomics was collected one day prior to surgery and linked to data from medical records. Patients were categorized into disease burden quartiles using the Western Ontario and McMaster Universities Osteoarthritis Index' (WOMAC) total score. Subsequently, study population's characteristics and expectations from surgery were analyzed stratified by disease burden. RESULTS A total of 196 patients were included (41 % male; mean age: 68.2 years). The median WOMAC was 52.0 (IQR: 41.0-58.0). Patients in Q1 were more often males (Q1: 63 % vs Q4: 29 %) and had a shorter duration of complaints with the impaired knee. They were also less restricted in social participation, reported less often signs of depression, and were less often treated with physiotherapy (Q1: 27 % vs Q4: 54 %). Furthermore, expectations from surgery were highest in patients with a low disease burden. CONCLUSION We found large variations in disease burden with a considerable number of patients undergoing TKA whose functional capacity is still maintained and for which guideline-recommended conservative treatment options are not fully exhausted. Further research on this subgroup as well as establishing an international consensus on specific thresholds for TKA indication are needed.

Abstract
The Oxford Knee Score (OKS) is a patient-reported outcome questionnaire typically used to assess function and pain in patients undergoing total knee replacement (TKR). However, research is inconclusive as to which preoperative factors are important in explaining variation in outcome following TKR. The operative records of 12,709 patients who underwent primary TKR over a 9-year period were analyzed. The following variables were collected for each patient: age, sex, body mass index (BMI), Index of Multiple Deprivation decile rank, side of operation, diagnosis, the American Society of Anaesthesiologists (ASA) grade, preoperative OKS, EQ-5D index score, EuroQol visual analog scale (EQ-VAS) score, the postoperative OKS at 1 and 2 years. Generalized linear regression models were performed at 1 and 2 years to investigate the effect of the preoperative variables on the postoperative OKS. The effect of age, sex, BMI, Index of Multiple Deprivation decile rank, diagnosis, ASA grade, preoperative OKS, EuroQoL five-dimensional (EQ-5D) index score, and EQ-VAS score were all statistically significant in explaining the variation in OKS at 1 and 2 years postoperatively, with critical level of significance of 0.05 (5%). Being male aged 60 to 69 years of normal BMI, ASA grade I (fit and healthy), living in an affluent area, not reporting preoperative anxiety/depression, were associated with an enhanced mean postoperative OKS at both 1 and 2 years. When adjusted for potential confounding, age of 60-69 years, male sex, normal BMI, lower ASA grade, higher Index of Multiple Deprivation and higher pre-operative EQ-5D, EQ-VAS and OKS were identified as factors that resulted in higher post-operative OKS after primary TKR.

Manipulation Under Anesthetic After Primary Knee Arthroplasty Is Associated With a Higher Rate of Subsequent Revision Surgery. J Arthroplasty 2020; 35:2640-2645.e2. [PMID: 32475786 DOI: 10.1016/j.arth.2020.04.015] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/02/2020] [Revised: 03/18/2020] [Accepted: 04/06/2020] [Indexed: 02/02/2023] Open
Abstract
AIM To determine the association between manipulation under anesthetic (MUA) after primary knee arthroplasty and subsequent revision surgery. METHODS Patients undergoing primary knee arthroplasty from April 2011 to April 2016 with minimum 1-year follow-up to April 2017 were identified from the national hospital episode statistics for England. The first arthroplasty per patient, per side, was included; cases with a record of subsequent infection or periprosthetic fracture were excluded. Patients undergoing MUA within 1 year to the same knee were identified, defining the populations for the MUA and non-MUA cohorts. Mortality-adjusted Kaplan-Meier survival analysis (revision arthroplasty) was performed to a maximum of 6 years. A Cox proportional hazards model was used to determine the hazard for revision, adjusting for type of primary arthroplasty, gender, age group, year, comorbidity index, obesity, regional deprivation, rurality, and ethnicity. RESULTS A total of 309,650 primary arthroplasty cases (309,650 patients) were included. MUA within 1 year was recorded in 6882 patients (2.22%; 95% confidence interval [95% CI], 2.17-2.28) defining the MUA cohort; all others were included in the parallel non-MUA cohort. At 6 years, the mortality-adjusted estimated implant survival rate in the MUA cohort was 91.2% (95% CI, 90.0-92.2) in comparison to 98.1% (95% CI, 98.0-98.2) in the non-MUA cohort. In the fully adjusted model, this corresponded to an adjusted hazard for revision of 5.03 (hazard ratio; 95% CI, 4.55-5.57). CONCLUSION Patients who underwent MUA within 1 year of primary arthroplasty were at a 5-fold increased risk of subsequent revision even after excluding cases of infection or fracture. Further investigation of the etiology of stiffness after primary knee arthroplasty and the optimal treatment options to improve outcomes is justified.

Abstract
The objective of this study was to examine variations in the determinants of joint replacement (JR) across gender and age, with emphasis on the role of social support and family dynamics. We analyzed data from the US Health and Retirement Study (1998-2010) on individuals aged 45 or older with no prior receipt of JR. We used logistic regression to analyze the probability of receiving knee or hip replacement by gender and age (<65, 65+). We estimated the effect of demographic, health needs, economic, and familial support variables on the rate of JR. We found that being married/partnered with a healthy spouse/partner is positively associated with JR utilization in both age groups (65+ group OR: 1.327 and <65 group OR: 1.476). While this finding holds for men, it is not statistically significant for women. Among women younger than 65, having children younger than 18 lowers the odds (OR: 0.201) and caring for grandchildren increases the odds (1.364) of having a JR. Finally, elderly women who report availability of household assistance from a child have higher odds of receiving a JR as compared with elderly women without a child who could assist (OR: 1.297). No effect of available support from children was observed for those below 65 years old and elderly men. Our results show that intrafamily dynamics and familial support are important determinants of JR; however, their effects vary by gender and age. Establishing appropriate support mechanisms could increase access to cost-effective JR among patients in need of surgery.

Abstract
OBJECTIVE To determine factors associated with orthopaedic surgeons' decision to recommend total joint replacement (TJR) in people with knee and hip osteoarthritis (OA). DESIGN Cross-sectional study in eleven countries. For consecutive outpatients with definite hip or knee OA consulting an orthopaedic surgeon, the surgeon's indication of TJR was collected, as well as patients' characteristics including comorbidities and social situation, OA symptom duration, pain, stiffness and function (Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC]), joint-specific quality of life, Osteoarthritis Research Society International (OARSI) joint space narrowing (JSN) radiographic grade (0-4), and surgeons' characteristics. Univariable and multivariable logistic regressions were performed to identify factors associated with the indication of TJR, adjusted by country. RESULTS In total, 1905 patients were included: mean age was 66.5 (standard deviation [SD], 10.8) years, 1082 (58.0%) were women, mean OA symptom duration was 5.0 (SD 7.0) years. TJR was recommended in 561/1127 (49.8%) knee OA and 542/778 (69.7%) hip OA patients. In multivariable analysis on 516 patients with complete data, the variables associated with TJR indication were radiographic grade (Odds Ratio, OR for one grade increase, for knee and hip OA, respectively: 2.90, 95% confidence interval [1.69-4.97] and 3.30 [2.17-5.03]) and WOMAC total score (OR for 10 points increase: 1.65 [1.32-2.06] and 1.38 [1.15-1.66], respectively). After excluding radiographic grade from the analyses, on 1265 patients, greater WOMAC total score was the main predictor for knee and hip OA; older age was also significant for knee OA. CONCLUSION Radiographic severity and patient-reported pain and function play a major role in surgeons' recommendation for TJR.

Abstract
Background: Total knee replacement (TKR) is a common procedure for the treatment of osteoarthritis that provides a substantial reduction of knee pain and improved function in most patients. We investigated whether sociodemographic factors could explain variations in the benefit resulting from TKR. Methods: Data were collected from 3 sources: the National Joint Registry for England, Wales, Northern Ireland, and the Isle of Man; National Health Service (NHS) England Patient Reported Outcome Measures; and Hospital Episode Statistics. These 3 sources were linked for analysis. Pain and function of the knee were measured with use of the Oxford Knee Score (OKS). The risk factors of interest were age group, sex, deprivation, and social support. The outcomes of interest were sociodemographic differences in preoperative scores, 6-month postoperative scores, and change in scores. Results: Ninety-one thousand nine hundred and thirty-six adults underwent primary TKR for the treatment of osteoarthritis in an NHS England unit from 2009 to 2012. Sixty-six thousand seven hundred and sixty-nine of those patients had complete knee score data and were included in the analyses for the present study. The preoperative knee scores were worst in female patients, younger patients, and patients from deprived areas. At 6 months postoperatively, the mean knee score had improved by 15.2 points. There were small sociodemographic differences in the benefit of surgery, with greater area deprivation (−0.71 per quintile of increase in deprivation; 95% confidence interval [CI], −0.76 to −0.66; p < 0.001) and younger age group (−3.51 for ≤50 years compared with 66 to 75 years; 95% CI, −4.00 to −3.02; p < 0.001) associated with less benefit. Cumulatively, sociodemographic factors explained <1% of the total variability in improvement. Conclusions: Sociodemographic factors have a small influence on the benefit resulting from TKR. However, as they are associated with the clinical threshold at which the procedure is performed, they do affect the eventual outcomes of TKR. Level of Evidence: Prognostic Level IV.

Abstract
PURPOSE It remains unclear which factors, patient- or disease-specific, are associated with electing to undergo operative management for de Quervain tendinopathy. Our null hypothesis was that no patient- or disease-specific factors would be associated with the choice of surgical treatment of de Quervain tendinopathy. METHODS We performed a retrospective review of consecutive patients diagnosed with de Quervain tendinopathy over 3 years by 1 of 3 fellowship-trained hand surgeons at an urban academic institution. Descriptive statistics were calculated for patient baseline and disease-specific characteristics. Cohorts were compared using bivariate analysis for all collected variables. Binary logistic regression with backward stepwise term selection was performed including independent predictors identified by bivariate analysis. RESULTS A total of 200 patients were identified for inclusion. Bivariate analysis revealed that surgically treated patients were significantly more likely to have Medicaid insurance, psychiatric illness history, and disabled work status. Regression analysis revealed an association between surgical treatment and 2 of the factors evaluated: Medicaid insurance status and psychiatric illness history. CONCLUSIONS Psychiatric illness and Medicaid insurance status are associated with undergoing surgical release of the first dorsal compartment. These findings support the use of a biopsychosocial framework when treating patients with de Quervain tendinopathy. TYPE OF STUDY/LEVEL OF EVIDENCE Prognostic IV.

Abstract
OBJECTIVE Preoperative pain and function is viewed as an important predictor of total knee arthroplasty (TKA) outcomes. We examined whether variations in pain and function outcomes existed at 12 months between two centres in Sweden and Australia, and whether this was explained by variations in patient presentation for TKA. METHODS This was a retrospective analysis of prospectively collected data. Patients from one centre in Australia (St. Vincent's Hospital (SVH), N = 516) and in Sweden (Trelleborg (TBG), N = 899) who underwent primary TKA between 2012 and 2013. The Western Ontario and McMaster Universities Arthritis Index (WOMAC) was analysed pre- and 12 months' post TKA from which non-response to surgery was determined using the OMERACT-OARSI criteria. Multiple linear regression analysis was used to examine the relationship between change in pain and function and surgery centre, adjusting for preoperative patient characteristics and surgical technique. RESULTS Despite worse preoperative outcomes in all subscales of the WOMAC for the SVH cohort, there were no clinically meaningful differences in 12-month WOMAC subscales nor change in WOMAC subscales between SVH and TBG. Almost identical proportions of patients were considered OMERACT-OARSI responders, 85.7% (SVH) and 85.9% (TBG), however for the SVH cohort 25 (4.9%) were moderate and 417 (80.8%) were high responders, compared to the TBG cohort of which 225 (25%) were moderate and 547 (60.9%) were high responders. CONCLUSION Despite differences in preoperative presentation between 2 countries, improvements in pain and function and the proportion of individual who responded to TKA surgery at 1 year were similar. Factors related to poor response to TKA surgery require further elucidation.

Abstract
OBJECTIVES The aim of this prospective cohort study was to examine whether MRI-detected osteoarthritis (OA)-structural changes at baseline could predict knee OA patients who would undergo total knee arthroplasty (TKA). METHODS In total, 128 end-stage medial-type knee OA patients were enrolled and followed up for 6 months. MRI using the whole-organ MRI scoring (WORMS) method, radiographic findings, visual analog scale (VAS) for pain and a patient-oriented outcome measure, and the Japanese Knee Osteoarthritis Measure (JKOM) were recorded at baseline. The area under the curve (AUC) was estimated to determine the discriminative value of the prediction models. RESULTS While 74 patients (57.8%) did not undergo TKA, the remaining 54 patients (42.2%) underwent TKA during this period. The AUCs of the receiver operating characteristic (ROC) curve for the activities of daily living (ADL) score evaluated by the JKOM ADL score [0.70 (95% CI: 0.60-0.79)] and osteophyte score [0.72 (0.64-0.81)] were 0.70 or greater. The JKOM ADL score (17/40) and the osteophyte score (30/98) showed relative risks (RR) of 2.61 (1.32-5.15) and 3.01 (1.39-6.52) for undergoing TKA, respectively. CONCLUSION The osteophyte score detected by MRI, in addition to ADL score, was found to be an important factor in determining whether the patient should undergo TKA.

Abstract
OBJECTIVES To determine socioeconomic inequalities in frequent knee pain (FKP), knee osteoarthritis (OA), and associated health-related quality of life (HRQoL) in Sweden. METHOD In 2007 a postal questionnaire about knee pain was sent to a random sample of 10 000 residents of Malmö, Sweden (7402 individuals responded). Subjects reporting pain with duration ≥ 4 weeks in one or both knees in the past 12 months were classified as having FKP. A random sample of 1527 subjects with and without FKP attended a clinical and radiographic knee examination and responded to generic and disease-specific HRQoL questionnaires. We used the individuals' level of education and occupation as socioeconomic status (SES) measures, and we calculated the relative index of inequality (RII) using Poisson regression with robust standard errors adjusted for age and gender. We applied weighting to account for a possible selection bias that might arise from non-responses in the study. RESULTS With education, the RIIs for FKP and knee OA were 0.71 [95% confidence interval (CI) 0.61-0.84] and 0.56 (95% CI 0.34-0.93), respectively. With occupation, the corresponding figures were 0.70 (95% CI 0.60-0.82) and 0.59 (95% CI 0.37-0.94), respectively. There were socioeconomic gradients in HRQoL in favour of people with better SES. RIIs for FKP and HRQoL but not knee OA were essentially similar after additional adjustment for mediators. CONCLUSIONS In Sweden there are socioeconomic gradients related to both FKP and knee OA as well as HRQoL in favour of people with better SES. SES should be taken into account in health resource allocation pertaining to knee-related disorders.

Abstract
Background and purpose - Assessment of potential disparities in access to care is a vital part of achieving equity in health and healthcare. We have therefore studied the effect of socioeconomic status (SES) on the rates of knee and hip replacement due to osteoarthritis. Methods - This was a cohort study in Skåne, Sweden. We included all residents aged ≥ 35 years with consultations between 2004 and 2013 for hip or knee osteoarthritis. We retrieved individual information on income, education, and occupation and evaluated the rates of knee and hip replacement according to SES, with adjustment for age and sex. Professionals, legislators, senior officials, and managers, and individuals with the longest education, served as the reference group. Results - We followed 50,498 knee osteoarthritis patients (59% women) and 20,882 hip osteoarthritis patients (58% women). The mutually adjusted rate of knee replacement was lower in those with an elementary occupation (hazard ratio (HR) = 0.81, 95% CI: 0.72-0.92), in craft workers and those with related trades (HR = 0.88, CI: 0.79-0.98), and in skilled agricultural/fishery workers (HR = 0.83, CI: 0.72-0.96), but higher in the 2 least educated groups (HR = 1.2 in both). The rate of hip replacement was lower in those with an elementary occupation (HR = 0.77, 95% CI: 0.68-0.87), in plant and machine operators/assemblers (HR = 0.83, CI: 0.75-0.93), and service workers/shop assistants (HR = 0.88, CI: 0.80-0.96). The rate of hip replacement was higher in the highest income group (HR = 1.1, 95% CI: 1.0-1.2). Interpretation - There was a lower rate of joint replacement in osteoarthritis patients working in professions often associated with lower socioeconomic status, suggesting inequity in access to care. However, the results are not unanimous, as the rate of knee replacement was higher in the least educated groups.

Abstract
INTRODUCTION Previous research findings regarding the association between the outcomes of total hip and knee arthroplasty and patients' socioeconomic status have been contradictory. Consequently, we wanted to analyse whether individual-level household income was associated with the risk of revision arthroplasty and whether the time span in days from the primary arthroplasty to the revision operation varied according to income quintile. MATERIALS AND METHODS All first total hip and knee arthroplasties performed due to primary osteoarthritis in Finland from 1998 to 2007 were included in the study. Cox proportional hazard regression modelling was applied in the analysis regarding the risk of revision after the primary operation, while Poisson regression modelling was applied in the analysis regarding differences in the time from the primary to the revision operation between income quintiles. RESULTS The relationship between household income and the risk of revision arthroplasty was not statistically significant. The relationship remained insignificant, even when age, sex, and other confounding factors were adjusted for or analyses concerned revision in short or long term. In both the total hip arthroplasty and knee arthroplasty populations, patients in the lowest income quintiles underwent revision surgery earlier than patients in the highest income groups, but this difference was not statistically significant. CONCLUSION The quality of arthroplasty as measured by the risk of revision does not seem to depend on patients' income quintile.

Abstract
Background Equal access to health care according to need is an important goal for health policy in Finland. Earlier research in Finland and elsewhere has mainly been cross-sectional, but the results have implied that the goal has not been fully realised in somatic specialist hospital care. This study examines trends in socioeconomic equity in use of somatic specialist hospital care. Methods We used register data on somatic specialist hospital admissions among 25–84 year-old persons in Finland in 1995–2010 with individually linked register-based socio-demographic information. We calculated age-standardised admission rates per 100,000 person years by income, examined risk ratios using Poisson regression models and computed concentration indices separately for men and women. Linear trends in the socioeconomic distribution of admissions and surgical procedures were estimated with linear regression models for annual concentration indices. Results Overall, use of somatic specialist hospital care decreased steadily throughout the study period. A stepwise inverse income pattern was found in hospitalisation risk and in non-surgical admissions: the lower the income group, the higher the risk. The relative admission risk was approximately two times higher in the lowest income group compared to the highest among both genders. Few differences were found in surgical admissions. Income group differences remained stable in hospitalisations and surgical admissions, but increased in non-surgical admissions during the study period. An inverse pattern of increasing operation rates with decreasing income was found in primary hip and knee replacement operations, and in lower limb amputations. A similar pattern emerged during the study period in coronary revascularisations. There were no differences were found in lumbar fusion or lumbar disc operations, prostatectomies or appendectomies. Income group differences in hysterectomies disappeared during the study period. Conclusions While the results of the current study suggest that use of somatic specialist care declined in line with improving population health in 1995–2010, the increase of socioeconomic health differentials was only partly reflected in the distribution of somatic specialist hospital care. Further research is needed to evaluate the need to improve use and content of specialised hospital care among the low-income groups in order to improve equity in health care.

Abstract
OBJECTIVE To examine the impact of access to primary care physicians (PCPs), geographic availability of orthopaedic surgeons, socioeconomic status (SES), proportion of older population (≥65 years) and proportion of rural population on orthopaedic surgeon office visits and orthopaedic surgery. DESIGN Population multilevel study. SETTING Ontario, Canada. PARTICIPANTS Ontario residents 18 years or older who had visits to orthopaedic surgeons or an orthopaedic surgery for musculoskeletal disorders in 2007/2008. PRIMARY AND SECONDARY OUTCOMES Office visits to orthopaedic surgeons and orthopaedic surgery. RESULTS Access to PCPs and the index of geographic availability of orthopaedic surgeons, but not SES, were significantly associated with orthopaedic surgeon office visits. There was a significant interaction between access to PCPs and orthopaedic surgeon geographic availability for the rate of office visits, with access to PCPs being more important in areas of low geographic availability of orthopaedic surgeons. After controlling for office visits with orthopaedic surgeons, the index of geographic availability of orthopaedic surgeons was no longer significantly associated with orthopaedic surgery. CONCLUSIONS The findings suggest that, particularly, in areas with low access to PCPs or with fewer available orthopaedic surgeons, residents are less likely to have orthopaedic surgeon office visits and in turn are less likely to receive surgery. Efforts to address adequate access to orthopaedic surgery should also include improving and facilitating access to PCPs for referral, particularly in geographic areas with low orthopaedic surgeon availability.

Abstract
The objective of this article was to investigate the existence of horizontal inequality in access to care for six categories of elective surgery in a publicly funded system, when care is rationed through waiting lists. Administrative waiting time data on all elective surgeries (n = 4,634) performed in Ostergötland, Sweden, in 2007 were linked to national registers containing variables on socioeconomic indicators. Using multiple regression, we tested five hypotheses reflecting that more resourceful groups receive priority when rationing by waiting lists. Low disposable household income predicted longer waiting times for orthopedic surgery (27%, p < 0.01) and general surgery (34%, p < 0.05). However, no significant differences on the basis of ethnicity and gender were detected. A particularly noteworthy finding was that disposable household income appeared to be an increasingly influential factor when the waiting times were longer. Our findings reveal horizontal inequalities in access to elective surgeries, but only to a limited extent. Whether this is good or bad depends on one's moral inclination. From a policymaker's perspective, it is nevertheless important to recognize that horizontal inequalities arise even though care is not rationed through ability to pay.

Abstract
The objective indicators which reflect the past results of end-stage knee osteoarthritis (OA) patients who have already received total knee arthroplasty (TKA) could be helpful for physicians to discuss with patients who are considering TKA. The aim of this prospective cohort study was to examine whether we could predict the knee OA patients who would receive TKA in advance based on baseline data, and to set cut-off points for receiving TKA. The two-hundred and forty end-stage medial-type knee OA patients were enrolled and followed up for 6 months while performing therapeutic exercises. Radiographic findings, visual analog scale for pain and a patient-oriented outcome measure, the Japanese Knee Osteoarthritis Measure (JKOM), were recorded at baseline. Relative risks (RRs) using the area under the curve (AUC) for a receiver operating characteristic (ROC) curve were calculated to evaluate several scores for receiving TKA. While 119 patients (55.3 %) did not undergo TKA, the remaining 96 patients (44.7 %) underwent TKA during this period. The AUCs of the ROC curve for the JKOM total score [0.71 (95 % CI 0.64-0.79)] were higher than those for radiographic parameters. Among the JKOM subcategories, JKOM category III, which indicates the condition in daily life, showed the highest AUC of 0.72 (0.65-0.80). The JKOM total score (65/100) and JKOM category III score (17/40) showed RRs of 2.20 (1.33-3.63) and 1.95 (1.18-3.22) for receiving TKA, respectively. The presence of disability in daily living was found to be an important factor determining whether the patient should undergo TKA.

BMC Public Health 2013; 13:812.

Abstract
Background Growing mortality differences between socioeconomic groups have been reported in both Finland and elsewhere. While health behaviours and other lifestyle factors are important in contributing to health differences, some researchers have suggested that some of the mortality differences attributable to lifestyle factors could be preventable by health policy measures and that health care may play a role. It has also been suggested that its role is increasing due to better results in disease prevention, improved diagnostic tools and treatment methods. This study aimed to assess the impact of mortality amenable to health policy and health care on increasing income disparities in life expectancy in 1996-2007 in Finland. Methods The study data were based on an 11% random sample of Finnish residents in 1988–2007 obtained from individually linked cause of death and population registries and an oversample of deaths. We examined differences in life expectancy at age 35 (e35) in Finland. We calculated e35 for periods 1996-97 and 2006-07 by income decile and gender. Differences in life expectancies and change in them between the richest and the poorest deciles were decomposed by cause of death group. Results Overall, the difference in e35 between the extreme income deciles was 11.6 years among men and 4.2 years among women in 2006-07. Together, mortality amenable to health policy and care and ischaemic heart disease mortality contributed up to two thirds to socioeconomic differences. Socioeconomic differences increased from 1996-97 by 3.4 years among men and 1.7 years among women. The main contributor to changes was mortality amenable through health policy measures, mainly alcohol related mortality, but also conditions amenable through health care, ischaemic heart disease among men and other diseases contributed to the increase of the differences. Conclusions The results underline the importance of active health policy and health care measures in tackling socioeconomic health inequalities.

Abstract
Background The reported association of smoking with risk of undergoing a total joint replacement (TJR) due to osteoarthritis (OA) is not consistent. We evaluated the independent association between smoking and primary TJR in a large cohort. Methods The electronic records of 54,288 men and women, who were initially recruited for the Second Australian National Blood Pressure study, were linked to the Australian Orthopaedic Association National Joint Replacement Registry to detect total hip replacement (THR) or total knee replacement (TKR) due to osteoarthritis. Competing risk regressions that accounted for the competing risk of death estimated the subhazard ratios for TJR. One-way and probabilistic sensitivity analyses were undertaken to represent uncertainty in the classification of smoking exposure and socioeconomic disadvantage scores. Results An independent inverse association was found between smoking and risk of THR and TKR observed in both men and women. Compared to non-smokers, male and female smokers were respectively 40% and 30% less likely to undergo a TJR. This significant association persisted after controlling for age, co-morbidities, body mass index (BMI), physical exercise, and socioeconomic disadvantage. The overweight and obese were significantly more likely to undergo TJR compared to those with normal weight. A dose–response relationship between BMI and TJR was observed (P < 0.001). Socioeconomic status was not independently associated with risk of either THR or TKR. Conclusion The strengths of the inverse association between smoking and TJR, the temporal relationship of the association, together with the consistency in the findings warrant further investigation about the role of smoking in the pathogenesis of osteoarthritis causing TJR.

Abstract
BACKGROUND This population-based cohort study has the objective to understand the sociodemographic characteristics and health conditions of patients who do not receive surgery within 18 months following an ambulatory visit to an orthopaedic surgeon. METHODS Administrative healthcare databases in Ontario, Canada were linked to identify all patients making an initial ambulatory visit to orthopaedic surgeons between October 1(st), 2004 and September 30(th), 2005. Logistic regression was used to examine predictors of not receiving surgery within 18 months. RESULTS Of the 477,945 patients in the cohort 49% visited orthopaedic surgeons for injury, and 24% for arthritis. Overall, 79.3% did not receive surgery within 18 months of the initial visit, which varied somewhat by diagnosis at first visit (84.5% for injury and 73.0% for arthritis) with highest proportions in the 0-24 and 25-44 age groups. The distribution by income quintile of patients visiting was skewed towards higher incomes. Regression analysis for each diagnostic group showed that younger patients were significantly more likely to be non-surgical than those aged 65+ years (age 0-24: OR 3.45 95%CI 3.33-3.57; age 25-44: OR 1.30 95%CI 1.27-1.33). The odds of not getting surgery were significantly higher for women than men for injury and other conditions; the opposite was true for arthritis and bone conditions. CONCLUSION A substantial proportion of referrals were for expert diagnosis or advice on management and treatment. The findings also suggest socioeconomic inequalities in access to orthopaedic care. Further research is needed to investigate whether the high caseload of non-surgical cases affects waiting times to see a surgeon. This paper contributes to the development of evidence-based strategies to streamline access to surgery, and to develop models of care for non-surgical patients to optimize the use of scarce orthopaedic surgeon resources and to enhance the management of musculoskeletal disorders across the care continuum.

Socio-economic position has no effect on improvement in health-related quality of life and patient satisfaction in total hip and knee replacement: a cohort study. PLoS One 2013; 8:e56785.

Abstract
INTRODUCTION Considerable evidence suggests that patients with more advantaged Socio-Economic Positions undergo Total Hip and Knee Replacement (THR/TKR) more often, despite having a lower need. We questioned whether more disadvantaged Socio-Economic Position is associated with an lower improvement in Health-Related Quality of Life (HRQoL) and a lower patient satisfaction after THR/TKR. METHODS Patients who underwent primary THR/TKR in one academic and three community hospitals between 2005 and 2009, were eligible for inclusion. The highest completed levels of schooling were aggregated to index social class. We compared the improvement in HRQoL and postoperative satisfaction with surgery (measured using the Short-Form 36 (SF36) and an 11-point numeric rating scale of satisfaction) between the aggregated groups of highest completed levels of schooling, using linear mixed model analysis, with center as a random effect and potential confounders (i.e. age, gender, Body Mass Index and Charnley's comorbidity classification) as fixed effects. RESULTS 586 THR patients and 400 TKR patients (40% of all eligible patients) agreed to participate and completed all questionnaires sufficiently. We found no differences in HRQoL improvement in any dimension of the SF36 in THR patients. Patients with a higher completed level of schooling had a larger improvement in role-physical (9.38 points, 95%-CI:0.34-18.4), a larger improvement in general health (3.67 points, 95%-CI:0.56-6.79) and a smaller improvement in mental health (3.60 points, 95%-CI:0.82-6.38) after TKR. Postoperative patient satisfaction did not differ between different highest completed level of schooling groups. DISCUSSION Completed level of schooling has no effect on the improvement in HRQoL and patient satisfaction in a Dutch THR population and a small effect in a similar TKR population. Undertreatment of patients with more disadvantaged Socio-Economic Position cannot be justified, given the similar improvement in HRQoL and postoperative level of satisfaction with surgery between the social groups examined.

Abstract
BACKGROUND The purpose of this study was to systematically examine the impact of insurance status on access to and utilization of elective specialty hand surgical care. We hypothesized that patients with Medicaid insurance or those without insurance would have greater difficulty accessing care both in obtaining local surgical care and in reaching a tertiary center for appointments. METHODS This retrospective cohort study included all new patients with orthopaedic hand problems (n = 3988) at a tertiary center in a twelve-month period. Patient insurance status was categorized and clinical complexity was quantified on an ordinal scale. The relationships of insurance status, clinical complexity, and distance traveled to appointments were quantified by means of statistical analysis. An assessment of barriers to accessing care stratified with regard to insurance status was completed through a survey of primary care physicians and an analysis of both patient arrival rates and operative rates at our tertiary center. RESULTS Increasing clinical complexity significantly correlated (p < 0.001) with increasing driving distance to the appointment. Patients with Medicaid insurance were significantly less likely (p < 0.001) to present with problems of simple clinical complexity than patients with Medicare and those with private insurance. Primary care physicians reported that 62% of local surgeons accepted patients with Medicaid insurance and 100% of local surgeons accepted patients with private insurance. Forty-four percent of these primary care physicians reported that, if patients who were underinsured (i.e., patients with Medicaid insurance or no insurance) had been refused by community surgeons, they were unable to drive to our tertiary center because of limited personal resources. Patients with Medicaid insurance (26%) were significantly more likely (p < 0.001) to fail to arrive for appointments than patients with private insurance (11%), with no-show rates increasing with the greater distance required to reach the tertiary center. CONCLUSIONS Economically disadvantaged patients face barriers to accessing specialty surgical care. Among patients with Medicaid coverage or no insurance, local surgical care is less likely to be offered and yet personal resources may limit a patient's ability to reach distant centers for non-emergency care.

Abstract
BACKGROUND Specially trained physiotherapists (advanced practice physiotherapists (APP)) are working in orthopaedic clinics to improve access to orthopaedic services and support chronic disease management. Little attention has been paid to the impact APPs may have on non-surgical patients. In non-surgical patients with hip or knee arthritis consulting an APP in an orthopaedic clinic, the objectives were to: 1) describe patients' recall of APP recommendations, use of self-management strategies, and barriers to management six weeks following consultation; and, 2) compare exercise behaviour and self-efficacy at baseline and six weeks. FINDINGS This was a single group pre-and post-intervention study of patients who saw an APP when consulting the orthopaedic departments of two hospitals. At baseline and six weeks participants completed the adapted Stanford Exercise Behaviour Scale (response options: none, < 60 minutes/week, 1-3 hours/week or > 3 hours/week), and the Chronic Disease Self-efficacy Scale (range 1-10; higher scores indicate higher self-efficacy). At follow-up participants completed questions on recall of APP recommendations, use of self-management strategies and barriers to management. Seventy three non-surgical patients with hip or knee arthritis participated, a response rate of 89% at follow-up. Seventy one percent of patients reported that the APP recommended exercise, of whom 83% reported exercising to manage their arthritis since the visit. Almost 50% reported an increase in time spent stretching; over 40% reported an increase in time spent walking or doing strengthening exercises at follow-up. Common barriers to arthritis management were time, cost and other health problems. Mean chronic disease self-efficacy scores significantly improved from 6.3 to 7.2 (p < 0.001). The mean difference was 0.95 (95% CI 0.43, 1.62); the effect size was 0.51. CONCLUSIONS This pilot study of an APP intervention for non-surgical patients referred for orthopaedic consultation showed promising results, particularly for enhancing use of conservative management strategies such as exercise.

Abstract
OBJECTIVES There are few Australian data that examine the association between total knee joint replacement (TKR) utilisation and socioeconomic status (SES). This study examined TKR surgeries with a diagnosis of osteoarthritis (OA) performed for residents of Barwon Statistical Division (BSD) for 2006-2007. DESIGN Cross-sectional. SETTING BSD, South-eastern Victoria, Australia PARTICIPANTS All patients who underwent a TKR for OA, 2006-2007, and whose residential postcode was identified as within the BSD of Australia, and for whom SES data were available, were eligible for inclusion. PRIMARY OUTCOME MEASURE Primary TKR data ascertained from the Australian Orthopaedic Association National Joint Replacement Registry. Residential addresses were matched with the Australian Bureau of Statistics census data, and the Index of Relative Socioeconomic Disadvantage was used to determine SES, categorised into quintiles whereby quintile 1 indicated the most disadvantaged and quintile 5 the least disadvantaged. Age-specific and sex-specific rates of TKR utilisation per 1000 person-years were reported for 10-year age bands. RESULTS Females accounted for 62.7% of the 691 primary TKR surgeries performed during 2006-2007. The greatest utilisation rates of TKR in males was 7.6 observed in those aged >79 years, and in 10.2 in females observed in those aged 70-79 years. An increase in TKR was observed for males in SES quintile four compared to quintile 1 in which the lowest utilisation which was observed (p=0.04). No differences were observed in females across SES quintiles. CONCLUSIONS Further investigation is warranted on a larger scale to examine the role that SES may play in TKR utilisation, and to determine whether any social disparities in TKR utilisation reflect health system biases or geographic differences.

Abstract
BACKGROUND Documented age, gender, race and socio-economic disparities in total joint arthroplasty (TJA), suggest that those who need the surgery may not receive it, and present a challenge to explain the causes of unmet need. It is not clear whether doctors limit treatment opportunities to patients, nor is it known the effect that patient beliefs and expectations about the operation, including their paid work status and retirement plans, have on the decision to undergo TJA. Identifying socio-economic and other determinants of demand would inform the design of effective and efficient health policy. This review was conducted to identify the factors that lead patients in need to undergo TJA. METHODS An electronic search of the Embase and Medline (Ovid) bibliographic databases conducted in September 2011 identified studies in the English language that reported on factors driving patients in need of hip or knee replacement to undergo surgery. The review included reports of elective surgery rates in eligible patients or, controlling for disease severity, in general subjects, and stated clinical experts' and patients' opinions on suitability for or willingness to undergo TJA. Quantitative and qualitative studies were reviewed, but quantitative studies involving fewer than 20 subjects were excluded. The quality of individual studies was assessed on the basis of study design (i.e., prospective versus retrospective), reporting of attrition, adjustment for and report of confounding effects, and reported measures of need (self-reported versus doctor-assessed). Reported estimates of effect on the probability of surgery from analyses adjusting for confounders were summarised in narrative form and synthesised in odds ratio (OR) forest plots for individual determinants. RESULTS The review included 26 quantitative studies-23 on individuals' decisions or views on having the operation and three about health professionals' opinions-and 10 qualitative studies. Ethnic and racial disparities in TJA use are associated with socio-economic access factors and expectations about the process and outcomes of surgery. In the United States, health insurance coverage affects demand, including that from the Medicare population, for whom having supplemental Medicaid coverage increases the likelihood of undergoing TJA. Patients with post-secondary education are more likely to demand hip or knee surgery than those without it (range of OR 0.87-2.38). Women are as willing to undergo surgery as men, but they are less likely to be offered surgery by specialists than men with the same need. There is considerable variation in patient demand with age, with distinct patterns for hip and knee. Paid employment appears to increase the chances of undergoing surgery, but no study was found that investigated the relationship between retirement plans and demand for TJA. There is evidence of substantial geographical variation in access to joint replacement within the territory covered by a public national health system, which is unlikely to be explained by differences in preference or unmeasured need alone. The literature tends to focus on associations, rather than testing of causal relationships, and is insufficient to assess the relative importance of determinants. CONCLUSIONS Patients' use of hip and knee replacement is a function of their socio-economic circumstances, which reinforce disparities by gender and race originating in the doctor-patient interaction. Willingness to undergo surgery declines steeply after the age of retirement, at the time some eligible patients may lower their expectations of health status achievement. There is some evidence that paid employment independently increases the likelihood of operation. The relative contribution of variations in surgical decision making to differential access across regions within countries deserves further research that controls for clinical need and patient lifestyle preferences, including retirement decisions. Evidence on this question will become increasingly relevant for service planning and policy design in societies with ageing populations.

Abstract
Knee-replacement surgery is frequently done and highly successful. It relieves pain and improves knee function in people with advanced arthritis of the joint. The most common indication for the procedure is osteoarthritis. We review the epidemiology of and risk factors for knee replacement. Because replacement is increasingly considered for patients younger than 55 years, improved decision making about whether a patient should undergo the procedure is needed. We discuss assessment of surgery outcomes based on data for revision surgery from national joint-replacement registries and on patient-reported outcome measures. Widespread surveillance of existing implants is urgently needed alongside the carefully monitored introduction of new implant designs. Developments for the future are improved delivery of care and training for surgeons and clinical teams. In an increasingly ageing society, the demand for knee-replacement surgery will probably rise further, and we predict future trends. We also emphasise the need for new strategies to treat early-stage osteoarthritis, which will ultimately reduce the demand for joint-replacement surgery.

Abstract
Deprivation has been recognized as a major determinant of health and is associated with several musculoskeletal conditions. This study examines the effect of deprivation on the incidence of carpal tunnel syndrome using a regional prospective audit database. Over a 6 year period there were 1564 patients diagnosed with CTS with an annual incidence of 72/100,000 population. There was a significant difference in population incidence of CTS from the most deprived (81/100,000) to the least deprived (62/100,000) (p = 0.003). Functional impairment was higher in the most deprived group compared with the least (DASH 56 vs 48, p = 0.001). The most deprived group exhibited the greatest exposure to occupation vibration (42.7%), and had the greatest risk of bilateral disease (OR = 2.33, p < 0.001). We report an association between socioeconomic deprivation and carpal tunnel syndrome, with the disease being more likely to be bilateral and have a poorer DASH score in the most deprived patients.

Abstract
BACKGROUND Differences in the use of hip and knee replacement by sex, age, ethnicity or socioeconomic status may lead to differences in disease severity between those who have surgery. METHODS Analyses used data collected from 117,736 patients in 2009-10 via the Patient Reported Outcome Measures (PROMs) programme in England. Adjusted differences were estimated in the Oxford Hip Score (OHS) or the Oxford Knee Score (OKS), both expressed on a scale from 0 to 48, and the proportion with longstanding problems (>5 years), expressed as odds ratios (ORs). RESULTS Women had more severe pain and disability than men on average (difference OHS 2.3 and OKS 3.3), but less often longstanding problems. Compared with white patients, average severity was higher in South Asian patients (difference OHS 2.7 and OKS 3.0) and in black patients (difference OHS 0.9 and OKS 1.6), who also more often had longstanding problems (OR 1.40 for hip and 1.54 for knee). Patients from deprived areas had more severe disease (difference OHS 3.6 and OKS 3.3 between least and most deprived quintile). CONCLUSIONS There is evidence that non-white and deprived patients tend to have hip and knee replacement surgery at a later stage in the course of their disease.

Abstract
Objective: To study the quality of life (QL) and social characteristics of patients submitted to total knee arthroplasty (TKA). Methods: The Brazilian validated version of the SF-36 Quality of Life Questionnaire was applied during the pre- and postoperative periods to assess the effect of TKA in QL. A semi-structured social questionnaire was used for the survey of patients’ socioeconomic profile. Results: Some characteristics were observed in the participants’ socioeconomic parameters, such as the predominance of females, age above sixty years old, family income up to three minimum salaries, patients’ participation in family income, living together with other cohabitants, educational level up to high school; and living in urban periphery housing. Regarding SF-36, there was a statistically significant rise in corresponding values in postoperative assessment when compared with the preoperative assessment in all domains. Conclusion: TKA was capable of bringing a significant improvement in quality of life. In terms of social and economic profile of this group of patients submitted to TKA, it was observed that this profile was predominantly female, aged over sixty years, with low educational level, and limited economic resources.

Abstract
Objective: To examine associations between disability and socioeconomic status (SES) in persons with hip radiographic OA (rOA) or symptomatic OA (sxOA) in the Johnston County Osteoarthritis Project. Methods: Cross-sectional analyses were conducted on individuals with hip rOA (708) or sxOA (251). rOA was defined as Kellgren-Lawrence ≥ 2. Educational attainment (<12 years or ≥12 years) and occupation (managerial or non-managerial) were individual SES measures. Census block group poverty rate (<12%, 12-25%, ≥25%) was the community SES measure. Disability was measured by the HAQ-DI and the WOMAC (function, pain, total). Covariates included age, gender, race, BMI, and presence of knee symptoms. Analyses examined associations of disability with each SES effect separately, followed by multivariable analyses using all SES variables, adjusting for covariates. Results: In models with single SES variables adjusted for covariates, WOMAC scores were associated significantly (p<0.05) with low educational attainment and non-managerial occupation in rOA and sxOA. HAQ was significantly associated with low educational attainment in rOA and sxOA and with high community poverty in rOA. In models including all SES variables, the patterns of association were similar although with diminished significance. There was indication that education was more strongly associated with HAQ and WOMAC function, while occupation was more strongly associated with WOMAC pain. Conclusion: Our data provide evidence that individual SES is an important factor to consider when examining disability and pain outcomes in older adults with hip OA.

Abstract
Knee joint replacement is an effective and cost-effective intervention for severe symptomatic osteoarthritis of the knee joint. However, utilisation rates vary hugely, there are no indications, it is difficult to know when (in the course of arthritis) it is best to operate, and some 10-20% of people who have this surgery are unhappy with the outcome, and have persistent pain. In this article we briefly discuss the variations in utilization of knee joint replacement, and then outline four different approaches to the selection and prioritisation of patients for this procedure. Consensus criteria, including appropriateness criteria are available, but if produced by professionals alone, they may conflict with the views of patients and the public. Databases and cohort studies can be used to attempt relating outcomes to baseline characteristics, but at present we can only account for a small percentage of the variance with this technique. Finally, we propose use of the 'capacity to benefit framework' to attempt providing guidance to both patients and healthcare professionals.

Abstract
OBJECTIVES To describe primary care management of knee pain, in relation to National Institute for Health and Clinical Excellence (NICE) OA guidelines, and examine variation in management by patient characteristics. METHODS Subjects were 755 adults aged ≥50 years who responded to baseline and 3-year surveys and had consulted primary care for knee pain. Medical records (1997-2006) were searched. Associations of having interventions from the outer circle (adjunctive treatments or Step 3) of the NICE guidelines with self-reported socio-demographic and knee-specific factors were determined. RESULTS Eighty per cent had received a Step 3 intervention. Thirty-eight per cent had been referred to secondary care, and 10% had received a knee replacement. Forty-three per cent had been prescribed an opioid and 41% an NSAID. Severe knee pain or disability at baseline and follow-up was the main association with receiving a Step 3 intervention [adjusted odds ratio (OR) 2.26; 95% CI 1.38, 3.70] and with referral (OR 2.57; 95% CI 1.72, 3.83). Older patients were less likely to be referred. Although non-significant, those of higher social class, in more affluent areas, older age or overweight or obese, appeared more likely to receive a knee replacement. Fifty per cent of those reporting severe knee pain or disability in both surveys had not been referred to secondary care. CONCLUSION Most of the older adults who consult primary care with knee pain receive at least one Step 3 intervention from the OA guidelines. Inequalities in the management and referral of knee problems in primary care were generally not observed, although there were some trends towards differences in likelihood of total knee replacement.

Abstract
The UK has a publicly funded health care system with open access to all. In the past, demand for services overwhelmed the resources available. Recent government initiatives have attempted to address this. To achieve shorter waiting times (and guaranteed waiting times), access to additional services has been purchased from the private sector under short-term initiatives, often at sites firth of the home health board. There has been a suspicion that patients from higher socioeconomic groups have benefited differentially from this by rapid access to private health care facilities, due to ease of transport. The aim of this study was to analyse whether a patient's socioeconomic group influenced their access to, and place of, surgery. Patients undergoing a primary total hip or knee arthroplasty in a single health region over a three-year period were identified and their social group was determined by postcode address. Analysis of 3888 patients operated on in four different treatment centres comparing the distribution of patients according to their social group, revealed no bias in the provision of treatment. The study group was comparable to the control population in that health region. In conclusion, the introduction of health policies to reduce time to orthopaedic treatment within one health board area has not resulted in patient bias.

Abstract
BACKGROUND Total joint replacement (TJR) of the hip or knee for osteoarthritis is among the most common elective surgical procedures. There is some inequity in provision of TJR. How decisions are made about who will have surgery may contribute to disparities in provision. The model of shared decision-making between patients and clinicians is advocated as an ideal by national bodies and guidelines. However, we do not know what happens within orthopaedic practice and whether this reflects the shared model. Our study examined how decisions are made about TJR in orthopaedic consultations. METHODS The study used a qualitative research design comprising semi-structured interviews and observations. Participants were recruited from three hospital sites and provided their time free of charge. Seven clinicians involved in decision-making about TJR were approached to take part in the study, and six agreed to do so. Seventy-seven patients due to see these clinicians about TJR were approached to take part and 26 agreed to do so. The patients' outpatient appointments ('consultations') were observed and audio-recorded. Subsequent interviews with patients and clinicians examined decisions that were made at the appointments. Data were analysed using thematic analysis. RESULTS Clinical and lifestyle factors were central components of the decision-making process. In addition, the roles that patients assigned to clinicians were key, as were communication styles. Patients saw clinicians as occupying expert roles and they deferred to clinicians' expertise. There was evidence that patients modified their behaviour within consultations to complement that of clinicians. Clinicians acknowledged the complexity of decision-making and provided descriptions of their own decision-making and communication styles. Patients and clinicians were aware of the use of clinical and lifestyle factors in decision-making and agreed in their description of clinicians' styles. Decisions were usually reached during consultations, but patients and clinicians sometimes said that treatment decisions had been made beforehand. Some patients expressed surprise about the decisions made in their consultations, but this did not necessarily imply dissatisfaction. CONCLUSIONS The way in which roles and communication are played out in decision-making for TJR may affect the opportunity for shared decisions. This may contribute to variation in the provision of TJR. Making the importance of these factors explicit and highlighting the existence of patients' 'surprise' about consultation outcomes could empower patients within the decision-making process and enhance communication in orthopaedic consultations.

Abstract
OBJECTIVE To explore geographical and sociodemographic factors associated with variation in equity in access to total hip and knee replacement surgery. DESIGN Combining small area estimates of need and provision to explore equity in access to care. SETTING English census wards. SUBJECTS Patients throughout England who needed total hip or knee replacement and numbers who received surgery. MAIN OUTCOME MEASURES Predicted rates of need (derived from the Somerset and Avon Survey of Health and English Longitudinal Study of Ageing) and provision (derived from the hospital episode statistics database). Equity rate ratios comparing rates of provision relative to need by sociodemographic, hospital, and distance variables. RESULTS For both operations there was an "n" shaped curve by age. Compared with people aged 50-59, those aged 60-84 got more provision relative to need, while those aged >or=85 received less total hip replacement (adjusted rate ratio 0.68, 95% confidence interval 0.65 to 0.72) and less total knee replacement (0.87, 0.82 to 0.93). Compared with women, men received more provision relative to need for total hip replacement (1.08, 1.05 to 1.10) and total knee replacement (1.31, 1.28 to 1.34). Compared with the least deprived, residents in the most deprived areas got less provision relative to need for total hip replacement (0.31, 0.30 to 0.33) and total knee replacement (0.33, 0.31 to 0.34). For total knee replacement, those in urban areas got higher provision relative to need, but for total hip replacement it was highest in villages/isolated areas. For total knee replacement, patients living in non-white areas received more provision relative to need (1.04, 1.00 to 1.07) than those in predominantly white areas, but for total hip replacement there was no effect. Adjustment for hospital characteristics did not attenuate the effects. CONCLUSIONS There is evidence of inequity in access to total hip and total knee replacement surgery by age, sex, deprivation, rurality, and ethnicity. Adjustment for hospital and distance did not attenuate these effects. Policy makers should examine factors at the level of patients or primary care to understand the determinants of inequitable provision.

Abstract
BACKGROUND Patient deprivation is associated with greater need for total hip and knee replacement surgery (THR/TKR) and a higher prevalence of risk factors for surgical complications. Our aim was to examine associations between deprivation and aspects of the inpatient episode for patients undergoing these procedures. METHODS We analysed socioeconomic variations in preoperative surgical risk, postoperative morbidity and length of stay for 655 patients undergoing elective THR/TKR at a large metropolitan hospital. Surgical risk was assessed using the orthopaedic version of the POSSUM scoring system, postoperative morbidity was assessed using the postoperative morbidity survey, and socioeconomic status was measured using the Index of Multiple Deprivation. We adjusted for age, sex, surgical site and primary vs. revision surgery. RESULTS We found only a modest, clinically insignificant socioeconomic gradient in preoperative surgical risk and no socioeconomic gradient in postoperative morbidity. There was a strong socioeconomic gradient in length of stay, but only for patients undergoing TKR. This was due to deprived patients being more likely to remain in hospital without morbidity following TKR. CONCLUSIONS Our findings suggest differential selection of healthier patients for surgery. Hospitals serving deprived communities may have excess, unfunded costs because of the increased length of stay of socioeconomically disadvantaged patients.

Abstract
OBJECTIVE People in rural areas live farther away from hospitals than do people in urban areas. Thus, there is concern that people living in rural areas may be less willing or able to undergo elective surgical procedures. This study was undertaken to determine whether Medicare beneficiaries in rural areas were less likely to have elective total knee or hip replacement surgeries compared with their urban counterparts. METHODS We performed a cross-sectional study of Medicare beneficiaries, controlling for age, sex, race/ethnicity, and economic status. Beneficiaries were assigned to rural versus urban areas based on their zip code of residence and the 10-point Rural-Urban Commuting Area designation. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated. RESULTS Compared with urban beneficiaries, rural beneficiaries were 27% more likely to have total knee or hip replacement surgeries (OR 1.27 [95% CI 1.26-1.28]). After adjusting for age, sex, race/ethnicity, median household income, average house value, mean poverty ratio, and state of residence, rural beneficiaries were still 14% more likely to have total joint replacement surgeries (OR 1.14 [95% CI 1.13-1.16]). Differential use of surgery before and after receiving Medicare eligibility did not explain the findings. While significant sex, racial, and ethnic disparities were present in both rural and urban areas, for the most part these disparities were ameliorated rather than accentuated in rural areas. CONCLUSION Contrary to expectations, our findings indicate that Medicare beneficiaries living in rural areas are more likely to undergo total knee or hip replacement surgeries.

Abstract
Abstract:The English government has given a commitment to improving access to health care services for particular groups perceived as being under-served, or served inappropriately, by existing services. In this article four examples of policies aimed at improving access are considered: enhancing the supply of services to under-served areas, changing the organization of services, setting targets to improve access, and empowering people to make choices. Policies aimed at improving access will work only if they address the source of inequities, which means identifying the key barriers to access and these barriers are unlikely to be uniform across sectors, services, and groups of people. Evidence on the success of these four types of intervention in terms of influencing access and equity of access is discussed, borrowing some concepts from the sociological literature that enable us to understand the importance of how barriers to access may arise for different services and different population groups. It is clear that some policies may not work as well as we would hope, or may even exacerbate inequities of access, because they fail to recognize the source of the particular barriers faced by some groups.

Abstract
BACKGROUND CONTEXT Access to care for poor/near poor patients is a concerning and growing problem within the American system of medical care. PURPOSE The objective of this study was to examine the relationship between health insurance status and access to spine care among patients below 65 years of age eventually receiving treatment at our tertiary academic medical center. STUDY DESIGN Descriptive study based on chart review and telephone interviews. PATIENT SAMPLE Two groups of 64 patients each with surgical pathology of limited complexity and limited comorbidities, one with Medicaid insurance and one with private, commercial insurance. OUTCOME MEASURES Reasons for referral, travel distance, travel time, frequency of visits, and proximity of fellowship-trained spinal surgeons. METHODS Two groups, each with 64 consecutive spine surgical patients, were studied and compared. Group One had "Medicaid" coverage and Group Two was privately insured. All patients (both groups) were treated surgically for similar pathology of limited complexity and had limited comorbidities. They were assessed to determine the difficulties they encountered in receiving care before referral to our medical center including factors such as referral by a local provider based on insurance status alone and travel time/distance/frequency to eventually receive care at our center. The availability of local care for these patients (fellowship-trained spine surgeons in their local area) was also assessed. RESULTS The great majority (78%) of poor/near poor patients with Medicaid coverage from counties at some distance from (and local to) our center were referred/deferred on the basis of insurance status alone given surgical problems which could have comfortably been addressed by orthopedic surgeons, neurosurgeons, or fellowship-trained spine surgeons local to the patient. This difficulty in access to care results in a significant burden (measured in time/travel/costs) for these patients. CONCLUSIONS The poor/near poor with Medicaid insurance have less access to local spine care than those with private, commercial health insurance. The implications (from both surgeon and patient perspectives) of this dilemma are discussed.

Abstract
Aims: Many countries experience persistent or increasing
socioeconomic disparities in specialist care. This study examines the
socioeconomic distribution of elective surgery from 1992 to 2003 in Finland.
Methods: Administrative registers were used to identify
common elective procedures performed in all public and private hospitals in
Finland in 1992–2003. Patients’ individual
sociodemographic data came from 1990–2003 census and employment
statistics databases. First coronary revascularisation, hip and knee
replacement, lumbar disc operation, cataract extraction, hysterectomy and
prostatectomy on residents aged 25–84 years were analysed.
Age-standardized procedure rates by income quintile were calculated for both
genders, and concentration indices were developed and applied to
age-standardized procedure rates in 5% income groups for each study year.
Results: Most procedure rates increased during the study
period. Three trends emerged: declining inequality for coronary
revascularisations, an increase and then a decline in cataract extractions and
primary knee replacements among men, and positive relationships between income
and treatment for hysterectomy and lumbar disc operations.
Conclusions: Our results suggest that structural
features – uneven availability, co-payments and plurality of
provision – sustain inequity in access; decreasing inequities
reflect directed service expansion. Increased attention to collective,
prospective funding of primary and specialist ambulatory care is required to
increase equity of access to elective surgery.
