The incidence of shoulder arthroplasty infection presents a substantial economic burden in the United States: a predictive model.

Background: Periprosthetic joint infections (PJIs) are a major cause of morbidity after shoulder arthroplasty. Prior national database studies have estimated the trends of shoulder PJI up to 2012.21 Since 2012, the landscape of shoulder arthroplasty has changed drastically with the expanding popularity of reverse total shoulder arthroplasty. The dramatic growth in primary shoulder arthroplasties is likely paralleled with an increase of PJI case volume. The purpose of this study is to quantify the rise in shoulder PJIs and the economic stress they currently place on the American healthcare system as well as the toll they will incur over the coming decade. Methods: The Nationwide Inpatient Sample database was queried for primary and revision anatomic total shoulder arthroplasty, reverse total shoulder arthroplasty, and hemiarthroplasty from 2011-2018. Multivariate regression was used to predict cases and charges through the year 2030 adjusted to 2021 purchasing power parity. Results: From 2011 to 2018, PJI was found to be 1.1% shoulder arthroplasties, from 0.8% (2011) to 1.4% (2018). Anatomic total shoulder arthroplasty experienced the greatest proportion of infections at 2.0%, followed by hemiarthroplasty at 1.0% and reverse total shoulder arthroplasty at 0.3%. Total hospital charges grew 324%, from $44.8 million (2011) to $190.3 million (2018). Our regression model projects 176% growth in cases and 141% growth in annual charges by 2030. Conclusion: This study demonstrates the large economic burden that shoulder PJIs pose on the American healthcare system, which is predicted to reach nearly $500 million in charges annually by 2030. Understanding trends in procedure volume and hospital charges will be critical in evaluating strategies to reduce shoulder PJIs.

Gender Disparities Among Professional Team Sports Medicine Physicians.

OBJECTIVE: Although recent trends from the Accreditation Council for Graduate Medical Education (ACGME) present encouraging growth of female representation in sports medicine, the field is still lagging behind other specialties. This study investigates gender disparities among physicians providing care for professional sports teams in male and female sports leagues. DESIGN: Information regarding physicians providing sports medicine care to professional teams obtained by database queries (May 2021). Chi-square analysis compared gender data of orthopaedic team physicians with American Orthopaedic Society for Sports Medicine (AOSSM) and American Academy of Orthopaedic Surgeons (AAOS) membership, residency, and fellowship census data. Primary care sports medicine physicians were compared with American Medical Society for Sports Medicine (AMSSM) and primary-care sports medicine fellowship census data. SETTING: Professional sports health care. STUDY POPULATION: Professional league physicians. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Gender, residency, and fellowship training of professional league physicians. RESULTS: Among a total of 608 team physicians, 572 (93.5%) were male and 40 (6.5%) were female. Orthopedic surgeons comprised 64.7% of the physicians. Fourteen (3.6%) team orthopedic surgeons were female. Thirty-five percent of team physicians were primary care sports medicine physicians. Twenty-six primary care sports medicine physicians (11.6%) were female. Orthopaedic female team physician representation overall was comparable with AOSSM and AAOS membership but significantly less than orthopaedic surgery residents and sports medicine fellows ( P < 0.01). Women's National Basketball Association orthopaedic team physicians were more represented than female membership among AOSSM, AAOS, and orthopaedic sports medicine fellows ( P < 0.01). Except for the WNBA, Premiere Hockey Federation, National Women's Soccer League, and United States Football League, female primary care sports medicine physicians were underrepresented in professional sports compared with AMSSM membership and primary care sports fellows ( P < 0.01). CONCLUSION: Overall, female representation is poor among orthopaedic surgeons and primary care physicians providing sports medicine care to professional teams. Leagues encompassing female athletes tend to have better representation of female physicians. LEVEL OF EVIDENCE: IV.

Elective Hand Surgery Is Delayed among Private Insurance Holders.

OBJECTIVES: Patients with private healthcare plans often defer nonemergent or elective procedures toward the end of the year once they have met their deductible. No previous studies have evaluated how insurance status and hospital setting may affect surgical timing for upper extremity procedures. Our study aimed to evaluate the influence of insurance and hospital setting on end-of-the-year surgical cases for elective carpometacarpal (CMC) arthroplasty, carpal tunnel, cubital tunnel, and trigger finger release, and nonelective distal radius fixation. METHODS: Insurance provider and surgical dates were gathered from two institutions' electronic medical records (one university, one physician-owned hospital) for those undergoing CMC arthroplasty, carpal tunnel release, cubital tunnel release, trigger finger release, and distal radius fixation from January 2010 to December 2019. Dates were converted into corresponding fiscal quarters (Q1-Q4). Using the Poisson exact test, comparisons were made between the case volume rate of Q1-Q3 and Q4 for private insurance and then for public insurance. RESULTS: Overall, case counts were greater in Q4 than the rest of the year at both institutions. There was a significantly greater proportion of privately insured patients undergoing hand and upper extremity surgery at the physician-owned hospital than the university center (physician owned: 69.7%, university: 50.3%; P < 0.001). Privately insured patients underwent CMC arthroplasty and carpal tunnel release at a significantly greater rate in Q4 compared with Q1-Q3 for both institutions. Publicly insured patients did not experience an increase in carpal tunnel releases during the same period at both institutions. CONCLUSIONS: Privately insured patients underwent elective CMC arthroplasty and carpal tunnel release procedures in Q4 at a significantly greater rate than publicly insured patients. This finding suggests private insurance status, and potentially deductibles, influence surgical decision making and timing. Further work is needed to evaluate the impact of deductibles on surgical planning and the financial and medical impact of delaying elective surgeries.

Ultrasound assessment after a subscapularis-sparing approach to total shoulder arthroplasty.

BACKGROUND: Although anatomic total shoulder arthroplasty (ATSA) has favorable outcomes, nearly all techniques involve subscapularis tendon release for shoulder joint access. Such takedown of the subscapularis may be associated with decreased function, instability, and pain. Subscapularis-sparing approaches have the theoretical benefits of improved function, decreased failure of the tendon reattachment site, and early range of motion and rehabilitation. The primary purpose of this study was to use ultrasound to assess the postoperative integrity of the subscapularis tendon and surrounding soft tissues after ATSA with a subscapularis-sparing technique through an extensile anterosuperior skin incision. Our hypothesis was that this subscapularis-sparing approach would have low rates of subscapularis disruption. METHODS: A consecutive cohort of patients who underwent subscapularis-sparing ATSA between 2014 and 2017 were included. Ultrasound was used to evaluate the rotator cuff tendons and deltoid postoperatively, and these were classified as intact, disrupted, or unable to be adequately visualized. Clinical outcome scores, range of motion, and strength measurements were also collected at 1-3 years postoperatively. RESULTS: Thirty-seven subscapularis tendons and 40 supraspinatus and infraspinatus muscles were adequately visualized and included for analysis. Of the subscapularis muscles, 32 (86%) were intact; 38 of the visualized supraspinatus muscles (95%) and 39 of the infraspinatus muscles (98%) were intact. No dehiscence or loss of integrity of the deltoid was noted. Clinical comparison between patients with disrupted subscapularis muscles and patients without such disruption demonstrated no difference in clinical outcome scores and postoperative range of motion but showed less strength in forward flexion, abduction, and external rotation. CONCLUSIONS: The rate of subscapularis disruption using a subscapularis-sparing approach for ATSA was low (14%), but the potential for tendon disruption was not eradicated. Favorable clinical outcomes support this surgical approach as a potential technique for ATSA.

Disparities Among Industry's Highly Compensated Orthopaedic Surgeons.

The prosperous financial relationship between physicians and industry remains a highly scrutinized topic. Recently, a publicly available website was developed in conjunction with the U.S. Affordable Care Act to shed light on payments from industry to physicians with the goal of increasing transparency. The purpose of this study was to assess possible relationships between industry payments and orthopaedic surgeon gender, subspecialty training, and practice settings. METHODS: A retrospective analysis was performed using publicly available information from the Centers for Medicare & Medicaid Services (CMS) to identify the 25 orthopaedic surgeons with the highest compensation from each of the 10 largest orthopaedic companies from 2013 to 2017. Statistical analyses were conducted to investigate the factors that contributed to payment differences. RESULTS: Among the 347 highest-compensated orthopaedic surgeons, only 1 woman (0.29%) was identified. Orthopaedic surgeons in the subspecialties of spine (32.9%), adult reconstruction (27.9%), and sports medicine (14.5%) made up a majority of the 25 highest earners. A larger proportion of the physicians in this study worked in private practice (57.6%) compared with an academic setting (42.4%). Orthopaedic surgeons who subspecialize in sports medicine had significantly higher total mean payment amounts when compared with all other specialties. The primary method of compensation was found to be through licensing or royalty payments. CONCLUSIONS: The large majority of orthopaedic surgeons who are highly compensated from industry are men. Among these, the greatest number specialize in the spine, while sports medicine surgeons receive significantly higher total mean payment amounts. Additional studies are warranted to evaluate the disparities between men and women and encourage policies to promote gender equality.

COVID-19 Impact on Orthopedic Surgeons: Elective Procedures, Telehealth, and Income.

OBJECTIVES: The purpose of this study was to investigate the response in orthopedic surgery to the coronavirus disease 2019 (COVID-19) pandemic across the United States by surveying surgeons about their care setting, timing of restrictions on elective surgery, use of telehealth, and estimated economic impact. METHODS: A survey was distributed via REDCap through state orthopedic organizations between April and July 2020. The 22-question digital survey collected information regarding restrictions on elective procedures, location of care, utilization of telehealth, and estimated reductions in annual income. RESULTS: In this study, 192 participants responded to the survey (average age 49.9 ± 11.0 years, 92.7% male). Responses primarily originated from Alabama (30.2%), Georgia (30.2%), and Missouri (16.1%). The remainder of the responses were grouped into the category "other." Respondents did not vary significantly by state in operative setting or income type (salary, work relative value units, or collections). Most of the participants documented elective procedure restrictions in hospital and ambulatory settings. The highest frequency of closures occurred between March 18 and 20 (47% in hospital, 51% in ambulatory). Of the participants, financial loss estimates varied across states (P = 0.005), with 50% of physicians claiming >50% losses of income in Alabama (24% Georgia, 10% Missouri, 31% other). Regarding telehealth, practices set up for these services before 2020 varied across states. None of the orthopedic practices in Alabama had telehealth before the COVID-19 pandemic (Missouri 25%, Georgia 9%, other 8%, P = 0.06); however, respondents generally were split when considering the anticipation of implementing telehealth into routine practice. CONCLUSIONS: Most practices did implement restrictions for elective clinic visits and procedures early during the pandemic. COVID-19 ultimately will result in a large revenue loss for elective orthopedic practices. Services such as telehealth may help offset these losses and help deliver orthopedic care to patients remotely.

Do Geographic Region, Pathologic Chronicity, and Hospital Affiliation Affect Access to Care Among Medicaid- and Privately Insured Foot and Ankle Surgery Patients?

OBJECTIVES: Studies have shown that patients enrolled in Medicaid have difficulty obtaining access to care compared with patients with private insurance. Whether variables such as geographic location, state expansion versus nonexpansion, and private versus academic affiliation affect access to care among foot and ankle surgery patients enrolled in Medicaid has not been previously established. The purpose of this study was to assess the differences in access to care between patients who are privately insured and those with Medicaid in need of foot and ankle consultation. Secondary objectives include assessment of whether access to care for foot and ankle patients with Medicaid differs between those with acute and chronic conditions, Medicaid expanded and unexpanded states, geographic regions within the United States, and academic versus private practices. METHODS: Twenty providers from each of five Medicaid-expanded and five nonexpanded states in different US geographic regions were randomly chosen via the American Orthopaedic Foot & Ankle Society directory. One investigator contacted each office requesting the earliest available appointment for their fictitious relative's acute Achilles tendon rupture or hallux valgus. Investigator insurance was stated to be Medicaid for half of the telephone calls and Blue Cross Blue Shield (BCBS) for the other half. Appointment success rate and average time to appointment were compared between private insurance and Medicaid. Results were further compared across geographic regions, between private and academic practices, and between urgent acute injury (Achilles rupture) and chronic nonurgent injury (hallux valgus). RESULTS: Appointments were successful for all 100 (100%) calls made with BCBS as the insurer, in comparison to 73 of 100 calls (73%) with Medicaid (P < 0.001). Both acute and chronic injury had significantly higher success rates with BCBS than Medicaid (P < 0.001). The appointment success rate was significantly lower with Medicaid than with BCBS (P ≤ 0.01) in all of the geographic regions. The success rate with Medicaid (66.7%) was significantly lower than with BCBS (100.0%, P < 0.001) for private practice offices, but not for academic practices. CONCLUSIONS: Patients with Medicaid experience fewer options when obtaining appointments for common nonemergent foot and ankle problems and may experience less difficulty scheduling appointments at academic rather than private institutions. The medical community should continue to seek and identify potential interventions which can improve access to orthopedic care for all patients and increase the visibility of practices that accept Medicaid.

Resilience correlates with patient reported outcomes after reverse total shoulder arthroplasty.

BACKGROUND: Personal and social factors may account for much of the variation in patient reported outcome scores, yet little evidence exists on how psychological properties affect patient outcomes following reverse total shoulder arthroplasty (rTSA). The objective of this study is to determine if resilience, characterised by the ability to return to a healthy level of function after experiencing stress, correlates with patient reported outcome scores after rTSA. HYPOTHESIS: Resilience score will correlate positively with patient reported outcomes after rTSA. METHODS: Seventy-three patients were identified that had undergone primary rTSA with minimum 2-year follow-up (4.7±1.8). These patients completed a phone survey that included the Brief Resilience Scale (BRS), a measure of general resilience in all aspects of life, along with American Shoulder and Elbow Surgeon (ASES), Penn, and Single Assessment Numerical Evaluation (SANE) scores. Mean outcome scores were calculated to identify any correlation between resilience and clinical outcomes. RESULTS: The mean BRS score was 23.8±4.8 (range 12.0-30.0), with 41 patients classified as normal resilience (NR), 17 patients as low resilience (LR), and 15 as high resilience (HR). Postoperative BRS scores correlated with ASES (r=0.31, p=0.008), Penn (r=0.25, p=0.03), and SANE score (r=0.32, p=0.007). The mean ASES score was 14.0 points lower in the LR group (77.0 points), compared to the HR group (91.0 points; p=0.04). Similarly, the LR group had a mean SANE score that was 18.6 points lower than the HR group (73.4 and 91.9 points, respectively; p=0.021). DISCUSSION: The observation that greater general life resilience correlates with lower pain intensity, lesser magnitude of limitations, and perception of greater normality of the shoulder after reverse total shoulder arthroplasty emphasises the importance of addressing personal and social health opportunities along with the physical in musculoskeletal care. Resilience may be a useful predictor of outcomes following rTSA. LEVEL OF EVIDENCE: III.

Patient Perception of Orthopedic Surgeon Reimbursement.

Significant attention has been directed at evaluating reimbursement rates to orthopedic surgeons for various surgical procedures. To evaluate patients' understanding of the surgeon reimbursement process, studies using patient surveys have been conducted to determine patients' perceptions of orthopedic surgeon compensation. To date, there has been no systematic review to consolidate the data of these studies. This study aimed to synthesize the findings of these individual studies across multiple subspecialties of orthopedic surgery to evaluate the potential discrepancy between how much patients believe orthopedic surgeons are reimbursed and the actual reimbursement rate. We performed a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to identify studies that report findings of patient perceptions of orthopedic surgeon reimbursement for various procedures. Searches were conducted using MEDLINE through PubMed, Embase, and Scopus. Summary estimates of reimbursement discrepancies across subspecialties and overall were reported as unweighted averages of the individual study results within each group. Twelve studies were identified that met inclusion criteria, constituting 4309 surveys. These survey studies measured patients' perceptions of how much orthopedic surgeons are reimbursed for common procedures, including anterior cruciate ligament reconstruction, arthroscopic meniscectomy, carpal tunnel release, rotator cuff repair, multiple spine procedures and total shoulder, hip, and knee arthroplasty. It was found that patients reported reasonable surgeon's fees to be 11.2 times more than actual Medicare reimbursement. Among individual studies, the largest discrepancies were seen in total hip arthroplasty (26 times), whereas the smallest difference was in anterior cruciate ligament reconstruction (1.6 times). On average, patients estimated Medicare reimbursement rates to be 5.9 times higher than the actual surgeon reimbursement. Patients consistently overestimate how much orthopedic surgeons are reimbursed for common orthopedic procedures. The results of this systematic review suggest that patients may value these procedures more than what Medicare reimburses. Such information may help educate the public, direct policy, and increase transparency between orthopedic surgeons and patients.

Attitudes and awareness of suture anchor cost: a survey of shoulder surgeons performing rotator cuff repairs.

BACKGROUND: The cost of health care in the United States accounts for 18% of the nation's gross domestic product and is expected to reach 20% by 2020. Physicians are responsible for 60%-80% of decisions resulting in health care expenditures. Rotator cuff repairs account for $1.2-$1.6 billion in US health care expenditures annually. The purpose of this study is to assess surgeons' cost awareness in the setting of rotator cuff repairs. The hypothesis is that practice environment and training affect cost consciousness and incentivization will lead to more cost-effective choices. METHODS: In this cross-sectional study, a 21-item survey was distributed via the email list services of the American Shoulder and Elbow Surgeons and Arthroscopy Association of North America. Data collected included demographics, variables regarding rotator cuff repair (technique, number of companies used, procedures per month), and knowledge of costs. RESULTS: Responses from 345 surgeons in 23 countries were obtained with the majority (89%) being from the United States. Most surgeons were "cost-conscious" (275, 70.7%). Of these surgeons, 62.9% are willing to switch suture anchors brands to reduce overall costs if incentivized. Cost-conscious surgeons were more likely to be fellowship trained in shoulder and elbow (51.81% vs. 38.57%, P = .048), be paid based on productivity (73.53% vs. 61.43%, P = .047), and receive shared profits (85.4% vs. 75%, P = .02). CONCLUSION: The majority of orthopedic surgeons are both cost-conscious and willing to change their practice to reduce costs if incentivized to do so. A better understanding of implant costs combined with incentives may help reduce health care expenditure.

The Cost Variability of Orthobiologics.

BACKGROUND: Mixed results exist regarding the benefit of orthobiologic injections. The purpose of this study was to assess the variability in costs for platelet-rich plasma (PRP) and stem cell (SC) injections and evaluate for variables that influence pricing. HYPOTHESIS: There will be significant variability in the cost of PRP and SC injections throughout the United States. STUDY DESIGN: Descriptive epidemiology study. LEVEL OF EVIDENCE: Level 3. METHODS: Calls were made to 1345 orthopaedic sports medicine practices across the United States inquiring into the availability of PRP or SC knee injections and associated costs. In addition to pricing, the practice type, number of providers, and population and income demographics were recorded. Univariate statistical analyses were used to identify differences in availability and cost between variables. RESULTS: Of the contacted offices that provided information on both PRP and SC availability (n = 1325), 268 (20.2%) offered both treatments, 550 (41.5%) offered only PRP injections, 20 (1.5%) offered only SC injections, and 487 (36.8%) did not offer either treatment. The mean ± SD cost of a PRP injection was $707 ± $388 (range, $175-$4973), and the mean cost of an SC injection was $2728 ± $1584 (range, $300-$12,000). Practices offering PRP and SC injections tended to be larger (PRP, 12.0 physicians per practice vs. 8.1 [P < 0.001]; SC, 13.6 vs 9.7 [P < 0.001]). Practices that offered PRP injections were located in areas with higher median household income (P = 0.047). Variables associated with higher cost of PRP injections included city population (P < 0.001) and median income of residents (P < 0.001). CONCLUSION: While the majority of sports medicine practices across the United States offer some type of orthobiologic injection, there exists significant variability in the cost of these injections. CLINICAL RELEVANCE: This study demonstrates the significant variability in costs of orthobiologic injections throughout the country, which will allow sports medicine physicians to appreciate the value of these injections when counseling patients on available treatment options.

Editorial Commentary: Save the Meniscus? Show Me the Money!

The meniscus is known to play a vital role in the knee joint from, shock absorption to increased contact area to joint lubrication. Repairing a torn meniscus costs money, but it can be even more expensive to perform a partial meniscectomy over the long term. Moreover, meniscal repair may result in an improved quality of life for the patient. One must consider both quality of life and costs when addressing repairable meniscal tears in patients. Repairing a vertical meniscus tear in the red-red zone in a young adult is a cost-effective strategy.

Does Medicaid expansion improve access to care for the first-time shoulder dislocator?

BACKGROUND: The purpose of this study was to assess the effect of individual state Medicaid expansion status on access to care for shoulder instability. METHODS: Four pairs of Medicaid expanded (Louisiana, Kentucky, Iowa, and Nevada) and unexpanded (Alabama, Virginia, Wisconsin, and Utah) states in similar geographic locations were chosen for the study. Twelve practices from each state were randomly selected from the American Orthopedic Society for Sports Medicine directory, resulting in a sample size of 96 independent sports medicine offices. Each office was called twice to request an appointment for a fictitious 16-year-old first-time shoulder dislocator with either in-state Medicaid insurance or Blue Cross Blue Shield (BCBS) private insurance. RESULTS: A total of 91 physician offices in 8 states were contacted by telephone. An appointment was obtained at 36 (39.6%) offices when calling with Medicaid and at 74 (81.3%) offices when calling with BCBS (P < .001). Thirty-five (38.5%) offices were able to make appointments for both types of insurance, 39 (42.9%) for only BCBS, 1 (1.1%) for only Medicaid, and 16 (17.5%) for neither. For Medicaid patients, an appointment was booked in 13 (27.7%) clinics from Medicaid expanded states and in 23 (52.3%) clinics from unexpanded states (P = .016). CONCLUSION: For a first-time shoulder dislocator, access to care is more difficult with Medicaid insurance compared with private insurance. Within Medicaid insurance, access to care is more difficult in Medicaid expanded states compared with unexpanded states. Medicaid patients in unexpanded states are twice as likely as those in expanded states to obtain an appointment.

The Cost-Effectiveness of Anterior Cruciate Ligament Reconstruction in Competitive Athletes.

BACKGROUND: Competitive athletes value the ability to return to competitive play after the treatment of anterior cruciate ligament (ACL) injuries. ACL reconstruction has high success rates for return to play, but some studies indicate that patients may do well with nonoperative physical therapy treatment. PURPOSE: To evaluate the cost-effectiveness of the treatment of acute ACL tears with either initial surgical reconstruction or physical therapy in competitive athletes. STUDY DESIGN: Economic and decision analysis; Level of evidence, 2. METHODS: The incremental cost, incremental effectiveness, and incremental cost-effectiveness ratio (ICER) of ACL reconstruction compared with physical therapy were calculated from a cost-effectiveness analysis of ACL reconstruction compared with physical therapy for the initial management of acute ACL injuries in competitive athletes. The ACL reconstruction strategy and the physical therapy strategy were represented as Markov models. Costs and quality-adjusted life-years (QALYs) were evaluated over a 6-year time horizon and were analyzed from a societal perspective. Quality of life and probabilities of clinical outcomes were obtained from the peer-reviewed literature, and costs were compiled from a large academic hospital in the United States. One-way, 2-way, and probabilistic sensitivity analyses were used to assess the effect of uncertainty in variables on the ICER of ACL reconstruction. RESULTS: The ICER of ACL reconstruction compared with physical therapy was $22,702 per QALY gained. The ICER was most sensitive to the quality of life of returning to play or not returning to play, costs, and duration of follow-up but relatively insensitive to the rates and costs of complications, probabilities of return to play for both operative and nonoperative treatments, and discount rate. CONCLUSION: ACL reconstruction is a cost-effective strategy for competitive athletes with an ACL injury.
