Abstract: Health-care expenses have been projected to increase from 17.7% of the U.S. gross domestic product (GDP) in 2014 to 19.6% in 2024. The unsustainable increase in health-care costs has contributed toward support for value-based health care (VBHC) reform. Contemporary VBHC reform programs relevant to orthopaedic surgery include the voluntary Bundled Payments for Care Improvement initiatives (BPCI and BPCI-Advanced) and the Comprehensive Care for Joint Replacement (CJR) program, a mandatory bundled payment program.The purported benefits of transitioning from volume-based reimbursement to value-based reimbursement include moving from a fragmented provider-centered care model to a patient-centered model, with greater care coordination and alignment among providers focused on improving value. VBHC models allow innovative strategies to proactively invest resources to promote value (e.g., the use of nurse navigators) while eliminating unnecessary resources that do not promote value. However, major concerns regarding VBHC include the absence of medical and socioeconomic risk stratification as well as decreased access for higher-risk patients.This article identifies the benefits and potential unintended consequences of VBHC reform, with a focus on joint arthroplasty. We also discuss some potential strategies to promote innovation and improve value without compromising access for vulnerable patients. [ABSTRACT FROM AUTHOR]

Background: The representation of women in orthopaedics in the United States remains among the lowest in all fields of medicine, and prior research has suggested that this underrepresentation may stem from lower levels of interest among female medical students. Of the many proposed reasons for this lack of interest, the male-dominated nature of the field is one of the most commonly cited. The purpose of this study was to determine the degree to which the representation of women among orthopaedic faculty and residents influences female medical students at that institution to apply for a residency in orthopaedics.Methods: Using data provided by the Association of American Medical Colleges, we identified all U.S. medical schools that were affiliated with an orthopaedic surgery department and an orthopaedic surgery residency program (n = 107). For each institution, data on the representation of women among the orthopaedic faculty and residents from 2014 through 2016 were collected, as well as data on the proportion of female medical school graduates who applied to an orthopaedic residency program from 2015 through 2017. The association between institutional factors and the female medical student orthopaedic application rate was assessed.Results: Of 22,707 women who graduated from medical school during the 3-year study period, 449 (1.98%) applied to an orthopaedic surgery residency program. Women who attended medical school at institutions with high orthopaedic faculty sex diversity were more likely to apply for a residency in orthopaedics (odds ratio [OR], 1.30; 95% confidence interval [CI], 1.04 to 1.64; p = 0.023), as were women who attended medical school at institutions with high orthopaedic resident sex diversity (OR, 1.30; 95% CI, 1.05 to 1.61; p = 0.019).Conclusions: In this study, we found that increased sex diversity among orthopaedic faculty and residents was associated with a greater likelihood that female medical students at that institution would apply for an orthopaedic residency. These results suggest that at least some of the factors currently impeding female medical student interest in orthopaedics may be modifiable. These findings may have important implications for efforts to improve the sex diversity of the field of orthopaedics going forward. [ABSTRACT FROM AUTHOR]

The article discusses the gaps of sex differences in osteoarthritis (OA) of the knee. It notes that OA is the most common form of arthritis and the leading cause of disability in the U.S. with 13.9% afflicting adults aged 25 and older. It states that OA is consequently a progressive disorder which involves extensive damage and inflammation of joint cartilage, joint capsule and the bone. It mentions in the incidence of OA has been established through epidemiologic studies.

The article presents an overview of the benefits of Medicare Part B coverage and of the role it plays in the coverage of inpatient and outpatient physician services, particularly those services which are offered by orthopedists and orthopedic surgeons. Physician reimbursement which is related to Medicare Part B is discussed.

The article presents commentary on a study which focused on pay received by male and female surgeons for performing total knee and hip arthroplasty under Medicare in the U.S. Topics discussed include the lack of women surgeons in orthopaedics; the number of women orthopaedic specialists in pediatrics, pediatric spine, and oncology; and the influence of unconscious bias on treatment recommendations for total knee arthroplasty.

The article focuses on the lesser percentage of women in orthopedic surgery training programs in the U.S. It discusses the factors that discourage women from pursuing careers in orthopedic surgery including their choice of lifestyle. It is suggested that an increase in the number of women surgeons on orthopedic faculty may boost the interest of women medical students in orthopedics as a career.

Objectives: To investigate the impact of insurance coverage on the adoption of customized individually made (CIM) knee implants and to compare patient outcomes and cost effectiveness of off-the-shelf and CIM implants.Methods: A system dynamics simulation model was developed to study adoption dynamics of CIM and meet the research objectives. The model reproduced the historical data on primary and revision knee replacement implants obtained from the literature and the Nationwide Inpatient Sample. Then the dynamics of adoption of CIM implants were simulated from 2018 to 2026. The rate of 90-day readmission, 3-year revision surgery, recovery period, time savings in operating rooms, and the associated cost within 3 years of primary knee replacement implants were used as performance metrics.Results: The simulation results indicate that by 2026, an adoption rate of 90% for CIM implants can reduce the number of readmissions and revision surgeries by 62% and 39%, respectively, and can save hospitals and surgeons 6% on procedure time and cut down cumulative healthcare costs by approximately $38 billion.Conclusions: CIM implants have the potential to deliver high-quality care while decreasing overall healthcare costs, but their adoption requires the expansion of current insurance coverage. This work presents the first systematic study to understand the dynamics of adoption of CIM knee implants and instrumentation. More broadly, the current modeling approach and systems thinking perspective could be used to consider the adoption of any emerging customized therapies for personalized medicine.

Currently, 13.7% of the adult American population smokes cigarettes. Although rates of cigarette smoking have decreased over time, those of e-cigarette usage have increased. Smoking rates are highest in American Indians/Alaskan Natives and adults whose highest education level is a General Educational Development certificate, who live in rural American areas, and who have an annual household income of less than $35,000. After arthroplasty, smoking is linked to impaired wound healing, superficial and deep wound infections, and aseptic loosening. Patients who smoke should be strongly encouraged to stop and be supported with smoking cessation programs. Monitoring smoking cessation with cotinine levels may be inaccurate because variations have been noted in race, ethnicity, and sex. Confirmation of cessation as a hard stop to surgery could increase existing healthcare disparities. The role of the surgeon in encouraging patients to stop smoking, at least temporarily, before total joint arthroplasty cannot be overemphasized., (Copyright © 2022 by the American Academy of Orthopaedic Surgeons.)

Mental illness affects 20.6% of American adults. The lifetime prevalence of depression and anxiety is 17% and 29%, respectively. In particular, women suffer more from mental illness than men. Racial and ethnic minorities experience disproportionate discrimination, which has been linked to depression, anxiety, and psychological distress. African Americans are more likely to be chronically depressed, have higher levels of impairment and more severe symptoms, and often have challenges accessing treatment. Poor mental health is associated with low socioeconomic status, prolonged hospital stays, psychosis, postoperative anemia, infection, and pulmonary embolism. For total hip and knee arthroplasty, mental health conditions have been linked to higher hospital charges, higher rates of nonroutine discharges, and an increased Charlson Comorbidity Index. Mechanisms to address mental health are varied and range from psychosocial to pharmacologic modalities. Optimization in these vulnerable patients includes appropriate preoperative screening, assessment of support systems, identifying resources, and providing a safe discharge plan., (Copyright © 2022 by the American Academy of Orthopaedic Surgeons.)

Malnutrition can negatively affect clinical outcomes in total hip and knee arthroplasty. Food security plays an important and complex role in nutritional status, and 10.5% of American households are currently food insecure. Rates of food insecurity are higher for women, Hispanic, and Black Americans, those of lower socioeconomic status, and those in rural areas. Undernutrition disproportionately affects the elderly, a cohort with a high burden of osteoarthritis. Strategies for optimization begin with a holistic assessment of the patient's nutritional status. Patients should have a body mass index >18.5 kg/m 2 , vitamin D level >30 ng/dL, albumin level >3.5 g/dL, transferrin level >200 mg/dL, and total lymphocyte count of >1,500 cells/mm 3 . We recommend that orthopaedic surgeons screen for malnutrition for all elective total hip/knee arthroplasty patients., (Copyright © 2021 by the American Academy of Orthopaedic Surgeons.)

Background: Providers of total hip and knee replacements are being judged regarding quality/cost by payers using competition-based performance measures with poor medical and no socioeconomic risk adjustment. Providers might assume that other providers shed risk and the perception of added risk can influence practice. A poll was collected to examine such perceptions., Methods: In 2019 a poll was sent to the 2800 surgeon members of the American Association of Hip and Knee Surgeons using Survey Monkey while protecting respondent anonymity/confidentiality. The questions asked whether the perception of poorly risk-adjusted medical comorbidities and socioeconomic risk factors influence surgeons to selectively offer surgery., Results: There were 474 surgeon responses. Prior to elective total hip arthroplasty/total knee arthroplasty, 95% address modifiable risk factors; 52% require a body mass index <40, 64% smoking cessation, 96% an adequate hemoglobin A1C; 82% check nutrition; and 63% expect control of alcohol 2. Due to lack of socioeconomic risk adjustment, 83% reported feeling pressure to avoid/restrict access to patients with limited social support, specifically the following: Medicaid/underinsured, 81%; African Americans, 29%; Hispanics/ethnicities, 27%; and low socioeconomic status, 73%. Of the respondents, 93% predicted increased access to care with more appropriate risk adjustment., Conclusion: Competition-based quality/cost performance measures influence surgeons to focus on medical risk factors in offering lower extremity arthroplasty. The lack of socioeconomic risk adjustment leads to perceptions of added risk from such factors as well. This leads to marginal loss of access for patients within certain medical and socioeconomic classes, contributing to existing healthcare disparities. This represents an unintended consequence of competition-based performance measures., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Background: Musculoskeletal urgent care centers are a new development in the urgent care landscape. Anecdotally, these centers are known to screen patients based on their insurance status, denying care to those with Medicaid insurance. It is important to know whether the practice of denying musculoskeletal urgent care to patients with Medicaid insurance is widespread because this policy could exacerbate existing musculoskeletal healthcare disparities., Questions/purposes: (1) Do musculoskeletal urgent care centers in Connecticut provide access for patients with Medicaid insurance? (2) Do musculoskeletal urgent care centers have the same Medicaid policies as the entities that own them? (3) Are musculoskeletal urgent care centers more likely to be located in affluent neighborhoods?, Methods: An online search was conducted to create a list of musculoskeletal urgent care centers in Connecticut. Each center was interviewed over the telephone using a standardized list of questions to determine ownership and Medicaid policy. Next, the entities that owned these musculoskeletal centers were called and asked the same questions about their Medicaid policy. Medicaid policy was compared between musculoskeletal urgent care centers and the practices that owned them. The median household income for each ZIP code containing a musculoskeletal urgent care center was compared with the median household income for Connecticut. The median household income was also compared between the ZIP codes of musculoskeletal urgent care centers that accepted or denied patients with Medicaid insurance., Results: Of the 29 musculoskeletal urgent care centers in Connecticut, only four (13%) accepted patients regardless of their insurance type, 19 (66%) did not accept any form of Medicaid insurance, and six (21%) required that certain requisites and stipulations be met for patients with Medicaid insurance to receive access, such as only permitting a patient for an initial visit and then referring them to a local hospital system for all future encounters, or only permitting patients with Medicaid insurance who lived in the same town as the clinic. All 29 musculoskeletal urgent care centers were owned by private practice groups and nine of 14 of these groups had the same policy towards patients with Medicaid insurance as their respective musculoskeletal urgent care centers. All 29 musculoskeletal urgent care centers were co-located in a private practice clinic office. Musculoskeletal urgent care centers were located in areas with greater median household incomes than the Connecticut state median (95% CI, USD 112,322 to USD 84,613 versus the state median of USD 73,781; p = 0.001)., Conclusions: Most musculoskeletal urgent care centers in Connecticut do not accept patients with Medicaid insurance and have similar or stricter Medicaid policies as the groups that own them. Additionally, musculoskeletal urgent care centers were located in affluent neighborhoods. These findings are important because they suggest private practices are using musculoskeletal urgent care centers to capture patients with more favorable insurance. This is likely a result of the relatively low Medicaid reimbursement rates in Connecticut and reflects a need for an increase in either reimbursement or incentives to treat patients with Medicaid insurance. The financial impact of capturing well-insured patients from public and academic medical centers and directing Medicaid patients to these urgent care centers is not known. Additionally, although most of these 29 musculoskeletal urgent care clinics denied care to patients with Medicaid, the specific healthcare disparities caused by decreased access to care must be further studied.

Introduction: Orthopaedic surgery is among the least diverse fields in all of medicine. To promote the recruitment of minorities, a commonly proposed strategy is to increase the exposure of minority medical students to orthopaedic surgeons and residents who are minorities themselves. This study examines the degree to which the racial/ethnic diversity of the orthopaedic faculty and residency program influences underrepresented in medicine (URM) medical students at that institution to pursue a career in orthopaedics., Methods: Using data provided by the Association of American Medical Colleges, we identified all US medical schools that were affiliated with an orthopaedic department and an orthopaedic residency program (n = 110). For each institution, data were collected on URM representation among the orthopaedic faculty and residents (2013 to 2017), as well as the proportion of URM medical students who applied to an orthopaedic residency program (2014 to 2018). The association between institutional factors and the URM medical student orthopaedic application rate was then assessed., Results: Of 11,887 URM students who graduated from medical school during the 5-year study period, 647 applied to an orthopaedic residency program (5.4%). URM students who attended medical school at institutions with high URM representation on the orthopaedic faculty were more likely to apply in orthopaedics (odds ratio 1.27, 95% confidence interval 1.04 to 1.55, P = 0.020), as were URM students at institutions with high URM representation in the residency program (odds ratio 1.45, 95% confidence interval 1.17 to 1.79, P < 0.001)., Discussion: The benefits of a diverse orthopaedic workforce are widely acknowledged. In this study, we found that increased URM representation among the orthopaedic faculty and residents was associated with a greater likelihood that URM medical students at that institution would apply in orthopaedics. We also suggest a set of strategies to break the cycle and promote the recruitment of minorities into the field of orthopaedic surgery.

A survey study was performed of individuals in an orthopedic clinic waiting room regarding their knowledge of Medicare reimbursement to orthopedic surgeons for primary THA and TKA. A total of 1200 surveys were submitted by individuals (median age 64 years, 61% female, 50% with Medicare as their primary insurance and 29% having had THA or TKA). The median amount respondents felt that a reasonable fee to the orthopedic surgeon for performing THA or TKA was $5000, while they estimated the Medicare reimbursement to be much less. When asked what was the most they would be willing to pay out-of-pocket to have the surgery performed or for advanced technology related to the procedure, the median was $2000. Most respondents were willing to wait 3-7 weeks for surgery to be performed. Participants tended to value THA and TKA more relative to Medicare payments and tended to overestimate Medicare reimbursement to surgeons for THA and TKA., (© 2013 Elsevier Inc.

A dramatic shortage of total hip arthroplasty (THA) and total knee arthroplasty (TKA) surgeons has been projected because fewer residents enter arthroplasty fellowships, and the demand for THAs/TKAs is rising. The purposes of this study were to ascertain the future supply of THA/TKA surgeons, to identify the criteria residents use to choose their fellowship specialty, and to assess resident perceptions of an arthroplasty career. Four hundred ninety-eight post-graduate year 3 and above residents completed the online survey. Residents most highly prioritize intellectual factors and role models/mentors in determining their fellowship specialty. In the face of a looming patient access-to-care crisis, the data from this study support a policy of highlighting the intellectual challenges and satisfaction of THA/TKA as a career and encouraging mentorship early in a resident's training., (Copyright © 2011 Elsevier Inc.

To evaluate the effects of the economic downturn on adult reconstruction surgery in the United States, a survey of the American Association of Hip and Knee Surgeons (AAHKS) membership was conducted. The survey evaluated surgical and patient volume, practice type, hospital relationship, total joint arthroplasty cost control, employee staffing, potential impact of Medicare reimbursement decreases, attitudes toward health care reform options and retirement planning. A surgical volume decrease was reported by 30.4%. An outpatient visit decrease was reported by 29.3%. A mean loss of 29.9% of retirement savings was reported. The planned retirement age increased to 65.3 years from 64.05 years. If Medicare surgeon reimbursement were to decrease up to 20%, 49% to 57% of AAHKS surgeons would be unable to provide care for Medicare patients, resulting in an unmet need of 92,650 to 160,818 total joint arthroplasty procedures among AAHKS surgeons alone. Decreases in funding for surgeons and inadequate support for subspecialty training will likely impact access and quality for Americans seeking adult reconstruction surgery., (Copyright © 2010 Elsevier Inc.
