“…The existence of such a registry, with this degree of followup, is unique in Australia. Therefore, the true rate of postdischarge complications, such as VTE and SSI, is poorly delineated in the Australian patient cohort (4,15). However, the rate of postoperative complications is consistent with prior publications and is consistent across time with published data from the SMART Registry (19,28).…”

“…Costs were extrapolated to the Australian population using AOANJRR data on the TJA performed over the same time period as the study (4). For the purposes of the model, it was assumed that the SVHM patient cohort was representative of the overall Australian arthroplasty patient cohort (4,15). The frequency of comorbid disease, operative factors, and postoperative complications in the Australian arthroplasty cohort were extrapolated from the SVHM cohort data.…”

Objective. Total joint arthroplasty (TJA) places a significant economic burden on health care resources. This cohort study examines the costs associated with arthroplasty in 827 patients undergoing hip and knee TJA from January 2011 to June 2012 at a single center in Melbourne, Australia. Methods. Data included total inpatient, outpatient, and readmissions costs in the 30 days following TJA. Factors associated with cost were modeled using negative binomial regression and extrapolated to the Australian population. Results. The base cost (i.e., the cost for a patient with no modifying factors) over the first 30 days following TJA was $13,060 Australian (AU) (interquartile range $12,126-14,067 AU). The median length of stay was 4 days (range 2-33 days) and 35 patients (4%) were readmitted in the first 30 days following index TJA, the majority of whom had a surgical site infection (SSI) (74%). The following factors were independently associated with increased costs: SSI, preoperative warfarin therapy, American Society of Anesthesiologists score of 3 or 4, hip TJA, increasing operation time, increasing postoperative blood transfusion requirements, other nosocomial infections, postoperative venous thromboembolism (VTE), pressure ulcers, postoperative confusion, and acute urinary retention. Based on data from the present study, the cost of TJA in Australia is estimated to exceed $1 billion AU per year. Preventable postoperative complications were major cost drivers: SSI and VTE added a further $97 million AU and $66 million AU, respectively, to arthroplasty costs in the first 30 days following surgery. Conclusion. This unique study has identified important factors influencing TJA costs and providing guidance for future research and resource allocation.

“…Similar variations were reported for THR ranging from 2.3 to 5.8. Such geographic variation in TJR rates has been also reported in other countries such as Australia [33], the United Kingdom [34], Finland [35], and Germany [36]. These differences, which often remain even after adjusting for age [36], have been attributed to various factors, including a lack of consensus regarding the indications for these procedures [24,32].…”

“…Their willingness to undergo surgery however is equal to their more educated peers; therefore, patient willingness does not account for the treatment discrepancy [11]. The disparity between patients with OA with low socioeconomic status and access to total joint surgery exists even in countries with equal access to health care [5,6,11]. Although these individuals are at risk for lower patient-reported outcomes than more educated patients, they still have marked improvements and benefit from the treatment.…”

Background Age, sex, and medical comorbidities may be associated with differences in patient-reported outcome scores after THA. Highest level of education may be a surrogate for socioeconomic status, but the degree to which this is associated with patient-reported outcomes after THA is not known.Questions/purposes We investigated the national Swedish Hip Arthroplasty Register for the association of education attainment on patient-reported outcomes 1 year after THA; specifically, we evaluated level of education attainment against health-related quality of life (HRQoL), pain reduction, and satisfaction with treatment 1 year after THA. Methods All THAs for osteoarthritis performed from 2005 through 2007 with complete patient-reported outcome measures (representing 49% of the THAs performed for this diagnosis) were selected from the Swedish Hip Arthroplasty Register. These cases were merged with national databases containing education attainment, marital status, and comorbidities (n = 11,464; mean age of patients, 64 years). The patient-reported outcome measure protocol included the HRQoL measure EuroQol five-dimension scale (EQ-5D), a VAS for pain, the Charnley classification survey, and a VAS addressing THA satisfaction. Linear regression analyses determined the association of preoperative patient factors with patient-reported outcomes. Results High education attainment was associated with higher HRQoL (EQ-5D index ß high = 0.03 ± 0.01; EQ VAS ß high = 2.6 ± 0.5) after THA, whereas those with This study was funded by the Swedish Hip Arthroplasty Register,
