    Exploring Economic Issues in Total Joint Arthroplasty

    Because the way in which orthopaedic surgeons are compensated for managing total joint arthroplasty patients continues to evolve, ICJR devoted an entire session to economic issues at the recent 11th Annual Winter Hip & Knee Course.

    The session featured presentations from Walter B. Beaver Jr., MD; William J. Hozack, MD; William J. Long, MD, FRCSC; Gwo-Chin Lee, MD; and Richard W. McCalden, MD, FRCSC, who explored various aspects of reimbursement, including:

    • Bundled payments
    • Strategies to reduce implant costs
    • Assessment of patient risk
    • Cost-effectiveness of joint replacement
    • Post-acute care costs

    Private Bundles: Where We Are Going

    Walter B. Beaver Jr., MD, shared the experience of his practice, OrthoCarolina Hip & Knee Center in Charlotte, North Carolina, with commercial bundles for hip and knee arthroplasty, including the steps he and his colleagues have taken to ensure that they maintain, or even improve patient outcomes as they decrease spending. He discussed:

    • How they determine if a patient will be in a bundle
    • How they assess risk and optimize patients before surgery
    • How they communicate across the continuum of care
    • How they manage post-acute services

    BCPI from the Rothman Perspective

    In 2015, surgeons from The Rothman Institute in Philadelphia, Pennsylvania, began participating in the voluntary Bundled Payments for Care Improvement (BPCI) initiative for joint replacement patients with Medicare insurance. Three years and roughly 10,000 patients later, they found that BPCI had no impact on their clinical routine or their billing routine and that they had generated $3 million per year.

    In his presentation on the Rothman experience with BPCI, William J. Hozack, MD, provided background on BPCI, described how he and his colleagues prepared for BPCI and why it worked for them, and discussed the future of value-based care. The bottom line, he said, is that the best financial performance comes from providing the best care for each patient.

    Value-Based Implants and Hospital-Vendor Alignment Advantages

    The cost of implants for joint replacement surgery is 60% higher today than in 2000, despite competition among companies, a near standardization of product lines, and near doubling of procedure volume, William J. Long, MD, FRCSC, from NYU Health and the Insall Scott Kelly Institute in New York, said in his presentation.

    With the increased demand for joint replacement, evolving payment strategies, and decreased reimbursement to providers, now is the time for surgeons to get involved in efforts to reduce implant costs. In his presentation, Dr. Long discussed how this can be accomplished through preferred vendor agreements, rep-less surgeries, use of an in-house technician to manage the implants, reduced implant and tray inventory, and the use of generic implants.

    Risk Stratification for TJA: Can We Safely Predict Who, Why, When, and Where?

    In 2019, the orthopaedic surgeon’s mantra, said Gwo-Chin Lee, MD, from the University of Pennsylvania in Philadelphia, should be minimize complications, reduce readmissions, and decrease costs for joint replacement surgery. One way to do this is to adopt rapid recovery protocols and consider outpatient surgery when it makes sense. Dr. Lee concluded that:

    • Preoperative patient selection and education are critical to minimizing complications and patient dissatisfaction.
    • Preoperative optimization of modifiable risk factors can potentially decrease the risks from surgery.
    • Risk stratification before elective joint replacement can help anticipate hospital resource allocation and discharge disposition.

    Is Joint Replacement Cost-Effective in the Obese and Morbidly Obese Patient?

    Patients who are obese have been found to be at higher risk for some complications of joint replacement surgery, but they also do as well as non-obese patients in terms of outcomes, such as pain reduction and improved function. Ninety-day costs are also higher, according to research from Richard W. McCalden, MD, FRCSC, and his colleagues from the London Health Sciences Center in London, Ontario, Canada, but again, outcomes are similar in obese and non-obese patients. [1,2]

    What was not clear from this research, Dr. McCalden said in his presentation, is whether joint replacement is cost-effective in obese and morbidly obese patients, whether there should be a cut-off for BMI in joint replacement patients, and whether providers should receive greater reimbursement for managing patients with a high BMI.

    Minimizing Post-Acute Discharge Costs

    Controlling costs associated with joint replacement surgery means controlling what goes on across the entire continuum of care for the hip or knee arthroplasty patient, from initial visit to post-discharge management. In his second presentation of the session, William J. Hozack, MD, from The Rothman Institute in Philadelphia, Pennsylvania, reviewed strategies for decreasing costs, including:

    • Reducing avoidable complications, readmissions, and reoperations by understanding how decisions about operating on certain patients could increase costs
    • Avoiding inappropriate variation in care by developing protocols that are based on consensus and/or evidence (if available), communicated to the entire team, and updated on a regular basis
    • Avoiding excessive costs of post-discharge care – physical therapy, home healthcare, inpatient rehabilitation, and skilled nursing facilities – due to variations in pricing
    • Understanding what care is unnecessary and what care is really needed during the entire perioperative period
