Abstract
INTRODUCTION This study aimed to assess cost-effectiveness of shoulder arthroplasty for osteoarthritis (OA) and rotator cuff tear arthropathy (CTA) from the perspective of a publicly funded health care system using patient data, health utilities and costs from a real-world situation. HYPOTHESIS Our hypothesis was that arthroplasty for OA is more cost-effective than for CTA. MATERIAL AND METHODS We gathered a cohort of patients with 153 anatomic total shoulder arthroplasty (TSA) for OA and 107 reverse shoulder arthroplasty (RSA) for CTA between years 2016-2020 at a university hospital. Short-term (mean 2.8years) shoulder function, health utilities and costs were obtained from prospectively collected data, and a Markov cohort simulation was carried out to assess lifetime cost-utility. The primary outcome measures were change in 15D score to calculate gain in quality-adjusted life years (QALYs) and change in Western Ontario osteoarthritis score of the shoulder (WOOS). RESULTS Both TSA and RSA restored shoulder function well, WOOS improvement was 59.7 (95% CI: 56.2-63.2) and 55.8 (95% CI: 50.4-61.2), respectively. The cost/QALY gained was 20,846.82 € for TSA and 38,711.90 € for RSA. The cost-utility was not remarkable sensitive to costs, discounting of future costs or estimated revision rates. However, the cost-effectiveness was very sensitive to change in 15D health utility scores and thus QALY gain, especially for RSA patients. DISCUSSION Shoulder arthroplasty restores shoulder function well in both OA and CTA. In health economic terms, RSA is less cost-effective than TSA in an everyday setting, mainly due to inferior improvement of health-related quality-of-life and reduced life expectancy of CTA patients.

Incidence of primary anatomic and reverse total shoulder arthroplasty in patients less than 50 years of age and high early revision risk. J Shoulder Elbow Surg 2023; 32:1901-1908. [PMID: 36868301 DOI: 10.1016/j.jse.2023.01.040] [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: 11/02/2022] [Revised: 01/07/2023] [Accepted: 01/22/2023] [Indexed: 03/05/2023]
Abstract
BACKGROUND Compared with the overall incidence of shoulder arthroplasty (SA), the relative risk and burden of revision may vary among patients specifically 40-50 years of age and less than 40 years of age. Our aim was to investigate the incidence of primary anatomic total SA and reverse SA, rate of revision within 1 year, and determine the associated economic burden in patients younger than 50 years. METHODS A total of 509 patients less than 50 years old who underwent SA were included, using a national private insurance database. Costs were based on the grossed covered payment. Multivariate analyses were performed to identify risk factors associated with revisions within 1 year of the index procedure. RESULTS SA incidence in patients less than 50 years old increased from 2.21 to 2.5 per 100,000 patients from 2017 to 2018. The overall revision rate was 3.9% with a mean time to revision of 96.3 days. Diabetes was a significant risk factor for revision (P = .043). Surgeries performed in patients less than 40 years old cost more than those performed in patients aged 40-50 years for both primary ($41,943 ± $23,842 vs. $39,477 ± $20,874) and revision cases ($40,370 ± $21,385 vs. $31,669 ± $10,430). CONCLUSIONS This study demonstrates that the incidence of SA in patients less than 50 years old is higher than previously reported in the literature and most commonly reported for primary osteoarthritis. Given the high incidence of SA and subsequent high early revision rate in this subset population, our data portend a large associated socioeconomic burden. Policymakers and surgeons should use these data for implementing training programs focused on joint sparing techniques.

Abstract
Purpose Our aim is to investigate the length of stay (LOS), cost of care (COC) and postoperative complications associated with reverse shoulder arthroplasty (RSA) in nonagenarians (people aged 90-99 years old). Methods We used the National Inpatient Sample (NIS) database to identify 59,925 patients who underwent RSA between 2016 and 2019, including 555 nonagenarians. We investigated the incidences of various medical and orthopedic postoperative complications in nonagenarians compared to their younger counterparts, as well as compared nonagenarians undergoing elective and non-elective surgery. Results Nonagenarians were less likely admitted for elective surgery (69.9% in nonagenarians vs 92.8% in controls, p < 0.001) and were subject to longer LOS (3.5 days in nonagenarians vs 1.89 days in controls, p < 0.001) and greater COC ($91,794.69 US in nonagenarians vs $79,574.12 US in controls, p < 0.001). Nonagenarians had increased incidences of hospital mortality (0.72% in nonagenarians vs 0.06% in controls, p < 0.001), pneumonia (1.44% in nonagenarians vs 0.37% in controls, p < 0.001), blood loss anemia (22.34% in nonagenarians vs 10.12% in controls, p < 0.001), and ARF (6.85% in nonagenarians vs 2.18% in controls, p < 0.001). Nonagenarians undergoing elective RSA had fewer complications than those requiring non-elective RSA. Conclusion Nonagenarians undergoing RSA are subject to increased LOS, COC, and postoperative complications. Despite this, we feel that the associated complications can be deemed acceptable and that with adequate preparation, the benefits of a successful RSA may outweigh the associated complications in elderly patients. This is important to aid clinicians and patients in making informed decisions for patient care and resource allocation, as well as highlights room for improvement in costs and hospital stay, as well as sheds light on persistent health disparities in orthopedic surgery.

Innovative technologies for reverse total shoulder arthroplasty in Australia: Market access challenges and implications for patients, decision-makers, and manufacturers.

Abstract
PURPOSE The success of reverse total shoulder arthroplasty (RTSA) has expanded its use for a broader range of shoulder indications worldwide. Evidence regarding the relative efficacy and long-term safety of medical technologies used in RTSA is subjected to rigorous assessment. Nonetheless, substantial challenges impede market access for innovative shoulder implant technologies for RTSA in Australia, resulting in delayed patient access. APPROACH This paper addresses the key challenges associated with generating evidence for the health technology assessments of innovative medical technologies for RTSA that are required for access to the Australian market. The transition to value-based care requires establishing a benchmarking reference that incorporates patient-reported outcome measures (PROMs) and combines revision outcomes with additional clinical outcomes to increase patient cohort sizes. Establishing the benchmark would require agreement on the outcome measures to be collected for each indication, and investment in reporting patient-reported outcomes for RTSA to the national orthopaedic registry. IMPLICATIONS FOR PRACTICE The need for increased flexibility in developing evidence for health technology assessment of RTSA medical technologies is required. Optimised approaches for benchmarking RTSA require extensive stakeholder discussions, including the agreement on evidence requirements and follow-up periods, selection of clinical outcomes, as well as pre-operative and post-operative PROMs as a value assessment.

Reverse Total Shoulder Arthroplasty Is the Most Cost-effective Treatment Strategy for Proximal Humerus Fractures in Older Adults: A Cost-utility Analysis. Clin Orthop Relat Res 2022; 480:2013-2026. [PMID: 35507306 PMCID: PMC9473782 DOI: 10.1097/corr.0000000000002219] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Accepted: 03/30/2022] [Indexed: 02/04/2023]
Abstract
BACKGROUND Proximal humerus fractures are the second-most common fragility fracture in older adults. Although reverse total shoulder arthroplasty (RTSA) is a promising treatment strategy for proximal humerus fractures with favorable clinical and quality of life outcomes, it is associated with much higher, and possibly prohibitive, upfront costs relative to nonoperative treatment and other surgical alternatives. QUESTIONS/PURPOSES (1) What is the cost-effectiveness of open reduction internal fixation (ORIF), hemiarthroplasty, and RTSA compared with the nonoperative treatment of complex proximal humerus fractures in adults older than 65 years from the perspective of a single-payer Canadian healthcare system? (2) Which factors, if any, affect the cost-effectiveness of ORIF, hemiarthroplasty, and RTSA compared with nonoperative treatment of proximal humerus fractures including quality of life outcomes, cost, and complication rates after each treatment? METHODS This cost-utility analysis compared RTSA, hemiarthroplasty, and ORIF with the nonoperative management of complex proximal humerus fractures in adults older than 65 years over a lifetime time horizon from the perspective of a single-payer healthcare system. Short-term and intermediate-term complications in the 2-year postoperative period were modeled using a decision tree, with long-term outcomes estimated through a Markov model. The model was initiated with a cohort of 75-year-old patients who had a diagnosis of a comminuted (three- or four-part) proximal humerus fractures; 90% of the patients were women. The mean age and gender composition of the model's cohort was based on a systematic review conducted as part of this analysis. Patients were managed nonoperatively or surgically with either ORIF, hemiarthroplasty, or RTSA. The three initial surgical treatment options of ORIF, hemiarthroplasty, and RTSA resulted in uncomplicated healing or the development of a complication that would result in a subsequent surgical intervention. The model reflects the complications that result in repeat surgery and that are assumed to have the greatest impact on clinical outcomes and costs. Transition probabilities and health utilities were derived from published sources, with costs (2020 CAD) sourced from regional costing databases. The primary outcome was the incremental cost-utility ratio, which was calculated using expected quality-adjusted life years (QALYs) gained and costs. Sensitivity analyses were conducted to explore the impact of changing key model parameters. RESULTS Based on both pairwise and sequential analysis, RTSA was found to be the most cost-effective strategy for managing complex proximal humerus fractures in adults older than 65 years. Compared with nonoperative management, the pairwise incremental cost-utility ratios of hemiarthroplasty and RTSA were CAD 25,759/QALY and CAD 7476/QALY, respectively. ORIF was dominated by nonoperative management, meaning that it was both more costly and less effective. Sequential analysis, wherein interventions are compared from least to most expensive in a pairwise manner, demonstrated ORIF to be dominated by hemiarthroplasty, and hemiarthroplasty to be extendedly dominated by RTSA. Further, at a willingness-to-pay threshold of CAD 50,000/QALY, RTSA had 66% probability of being the most cost-effective treatment option. The results were sensitive to changes in the parameters for the probability of revision RTSA after RTSA, the treatment cost of RTSA, and the health utilities associated with the well state for all treatment options except ORIF, although none of these changes were found to be clinically realistic based on the existing evidence. CONCLUSION Based on this economic analysis, RTSA is the preferred treatment strategy for complex proximal humerus fractures in adults older than 65 years, despite high upfront costs. Based on the evidence to date, it is unlikely that the parameters this model was sensitive to would change to the degree necessary to alter the model's outcome. A major strength of this model is that it reflects the most recent randomized controlled trials evaluating the management of this condition. Therefore, clinicians should feel confident recommending RTSA for the management of proximal humerus fractures in adults older than 65 years, and they are encouraged to advocate for this intervention as being a cost-effective practice, especially in publicly funded healthcare systems wherein resource stewardship is a core principle. Future high-quality trials should continue to collect both clinical and quality of life outcomes using validated tools such as the EuroQOL-5D to reduce parameter uncertainty and support decision makers in understanding relevant interventions' value for money.

Abstract
BACKGROUND Movement toward providing value-based musculoskeletal care requires understanding the cost associated with surgical care as well as the drivers of these costs. The aim of this study was to investigate the effect of common medical comorbidities and specific total elbow arthroplasty (TEA) indications on reimbursement costs throughout the 90-day TEA episode of care. The secondary aim was to identify the drivers of these costs. METHODS Administrative health claims for patients who underwent orthopedic intervention between 2010 and 2020 were queried using specific disease classification and procedural terminology codes from a commercially available national database of 53 million patients. Patients with commercial insurance were divided into various cohorts determined by different surgical indications and medical comorbidities. The reimbursement costs of the surgical encounter, 89-day postoperative period, and total 90-day period in each cohort were evaluated. The cost drivers for the 89-day postoperative period were also determined. Analyses were performed using descriptive statistics and the Kruskal-Wallis test for comparison. RESULTS A total of 378 patients who underwent TEA were identified. The mean reimbursement cost of the surgical encounter ($13,393 ± $8314) did not differ significantly based on patient factors. The mean reimbursement cost of the 89-day postoperative period ($4232 ± $2343) differed significantly when stratified by surgical indication (P < .0001) or by medical comorbidity (P < .0001). The indication of rheumatoid arthritis ($4864 ± $1136) and the comorbidity of chronic kidney disease ($5873 ± $1165) had the most expensive postoperative period. In addition, the total 90-day reimbursement cost ($16,982 ± $4132) differed significantly when stratified by surgical indication (P = .00083) or by medical comorbidity (P < .0001), with the indication of acute fracture ($18,870 ± $3971) and the comorbidity of chronic pulmonary disease ($19,194 ± $3829) showing the highest total 90-day cost. Inpatient costs related to readmissions represented 38% of the total reimbursement cost. The overall readmission rate was 5.0%, and the mean readmission cost was $16,296. CONCLUSION TEA reimbursements are significantly influenced by surgical indications and medical comorbidities during the postoperative period and the total 90-day episode of care. As the United States transitions to delivering value-based health care, the need for surgeons and policy makers to understand treatment costs associated with different patient-level factors will expand.

Abstract
Study of the outcome of treatment of shoulder conditions has emphasized subjective evaluation of outcomes including a variety of disease, region, and joint-specific tools. In response to the rapidly rising cost of health care, further interest has been directed to cost-effectiveness and value. Comparison of the outcomes of different shoulder conditions with each other, other musculoskeletal, and nonorthopedic conditions requires more generalized outcome tools, especially when considering cost-effectiveness and utility analysis. The concept of quality of life (QoL) was developed to satisfy this goal, and there are a variety of general health and QoL assessments tools available. The purpose of this study is to review the concept of health-related QoL and discuss health-related QoL measures as they relate to shoulder conditions.
