Introduction. Cardiac events have been found to occur with increased frequency in total joint arthroplasty (TJA) patients >65 y/o without known coronary artery disease (CAD). Avoidance of readmissions for cardiac events is paramount with bundled payment programs. It has been thought that many of these patients may have undiagnosed CAD because of sedentary life styles brought on by chronic osteoarthritis. The purpose of this study is to assess with Coronary Computed Tomographic Angiography (CCTA) the prevalence and severity of CAD in patients >65 y/o for elective TJA. Methods. 126 elective patients that were part of a total hip and knee bundled payment program were referred for cardiac evaluation with CCTA if they were >65 but <70 y/o with a history of heart disease or 2 risk factors or were >70 y/o. CCTA was acquired on all patients unless they had a history of a severe allergic reaction to contrast, GFR <50 ml/min., the presence of atrial fibrillation, or declined the test. All images were evaluated by an experienced reader. Arterial narrowing of 70% diameter or greater was classified as significant CAD. Intermediate lesions <70% were reclassified as significant if CT-FFR (Functional flow reserve) was < or = 0.80. Results. Excluding the 12 patients with known CAD who had stents or coronary artery bypass graft (CABG), the remaining 114 patients were classified into three groups. 34/114 (29.8%) had no CAD (Group A). 75/114 (65.8%) had (Group B). 5/114 (4.4%) had > or = 70% stenosis. Group C included one patient who had <70% stenosis but had CT-FFR <80%. Of 17 patients with known CAD with >70% or heart CT-FFR <80%, or prior stents/CABG, one patient was predicted to be high risk of a cardiac event because of a complex plaque with an ulcer, history of suppressed paroxysmal atrial fibrillation, and withdrawal from apixaban. He was nurse navigated throughout his hospital course and post discharge only to be recalled to the hospital to be rescued with cardiac stenting. Conclusion. Patients >65 y/o having TJA without a cardiac history were found to have a 4.4% prevalence of significant CAD. When added to the patients with known CAD, the overall prevalence was 13.5%. One patient had complex plaque predictive of a cardiac event. As the US population ages and TJA becomes more prevalent with greater pressure to reduce costs by bundling and shifting to outpatient surgery, further data needs to be collected to better understand CAD in TJA patients >65 y/o

Introduction. Bundled budgeting of payments for joint replacement services has become increasing common in an effort to improve quality while lowering cost. In the US, some Medicare bundled payment programs are voluntary whereas some now are mandatory. Large medical care and medical management organizations have largely been assigned or seized control of management of these programs, leaving the surgeon in a subordinate role. The current abstract describes an experience where surgeons provide leadership and accept responsibility in bundled payment program. Methods. We engaged a collective of 16 different private company orthopedic physician groups to apply to become episode initiators under under the Medicare Bundled Payment for Care Improvement (BPCI) models 2 and 3. The application process itself provided historical. cost data, enabling each group to independently decide whether or not to proceed with the BPCI. Results. Ultimately, 7 of the private orthopedic groups decided to continue with the BPCI initiative. At the first quarter reconciliation, savings ranged from 9% to 17% across the participating groups. Conclusion. It is possible and potentially preferable for surgeons to take a primary role in accepting responsibility and leadership in the comprehensive care of joint replacement patients. The surgeons are those who determine the indications for and perform the surgery, accept much of the risk, and typically maintain a career long relationship with the patient. As such, the surgeon is also in the best position to achieve the ultimate goals of improved quality which simultaneously controlling cost. Our experience thus far supports that view that the more leadership surgeons provide in value base care provision, the more our patients and health care system will benefit from optimization of care delivery

The high and ever increasing cost of medical care worldwide has driven a trend toward new payment models. Event based models (such as bundled payment for surgical events) have shown a greater potential for care and cost improvement than population-based models (such as accountable care organizations). Since joint replacement is among the most frequent and costly surgical events in medicine, bundled payments for joint replacement episodes have been at the forefront of evolution from fee-for-service to value-based care models and episode-based healthcare reform in general. Our education as surgeons in medical school, residency, fellowship, and in continuing education has been almost entirely non-economic in focus. Yet, we surgeons are now evolving from being primarily responsive for our patients' medical care to being also responsible for all expenditures associated with our patients' care. Similarly, while the cost of our patients' care was not even available to us, every dollar of expenditure for a patient's episode of care is now available to us in some circumstances. For example, a typical primary joint replacement episode may cost $30,000 for a patient insured by Medicare in the US. A surgeon performing 400 joint replacements per year is therefore authorizing upwards of $12M a year in health care spending by making the decisions to perform reconstructive procedures on those patients. The risk for value-based surgical episodes of care can be born by various entities including hospital systems or the surgeons themselves. Recent evidence demonstrates that quality improves and cost decreases more rapidly when surgeons take primary responsibility and risk for episodes of care as compared to when a hospital system or third party takes primary responsibility and risk. Yet, as surgeons, our education in the field of medical economics, value-based episodes of care, and payment reform is only just beginning. The more we understand about the cost and value of the services that we order for our patients, the more leadership can provide as healthcare evolves. The current presentation will describe the specific cost of care for the primary joint replacement patient preliminary experience with accepting risk and responsibility for these patients. It is likely that our patients will be best served if we surgeons provide as much leadership as possible in their care, both medically and economically

Wound closure is not often an area that is discussed by orthopaedic surgeons. We commonly attend meetings and talks related to different types of implants and surgical technique but in reality the wound and how we close it maybe one of the most important aspects of a surgical procedure. The avoidance of wound complications such as unplanned clinic visits, readmissions, reoperations and deep infections are very important as we move into a world of bundled payments and public reporting of complications. Not to mention the poor results for the patients when wound complications occur. Often there is little thought about how wound closure and surgical dressings could affect surgical site healing. We all have a common belief that blisters, drainage and surgical site infections are rare. In the literature it has been shown that the method of wound closure can influence skin and soft tissue perfusion. Which closure techniques can achieve physiologic blood flow, which may improve wound healing? This talk will cover topics related to reducing the dead space, avoidance of hematoma formation and what the literature says regarding different types of wound closure materials

Background. In surgeon controlled bundled payment and service models, the goal is to reduce cost but preserve quality. The surgeon not only takes on risk for the surgery, but all costs during 90 days after the procedure. If savings are achieved over a previous target price, the surgeon can receive a monetary bonus. The surgeon is placed in a position to optimize the patients preoperatively to minimize expensive postoperative readmissions in a high risk population. Traditionally, surgeons request that primary care providers medically clear the patient for surgery with cardiology consultation at their discretion, and without dictating specific testing. Our participation in the Bundled Payments for Care Improvement (BPCI) program for total hip and knee replacement surgeries since 1/1/15 has demonstrated a significant number of patients having costly readmissions for cardiac events. Objective. To determine the medical effectiveness and cost savings of instituting a new innovative cardiac screening program (Preventive Cardio-Orthopaedics) for total hip and knee replacement patients in the BPCI program and to compare result to those managed in the more traditional fashion. Methods. The new screening program was instituted on 11/1/17 directed by an advanced cardiac imaging cardiologist (EH). Testing included an electrocardiogram, echocardiogram, carotid and abdominal ultrasound, and coronary computed tomography angiography (CCTA). If needed, a 3 day cardiac rhythm monitor was also performed. Four of the ten physicians in our group performing hip and knee replacement surgeries participated. Charts of readmitted patients were reviewed to determine past medical history, method of cardiac clearance, length and cost of readmission. Results. 2,459 patients had total hip or knee replacement in the BPCI program between 1/1/15 and 10/31/17 prior to instituting the new program. All had complete 90 day postoperative readmission data supplied by the CMS, with 25 (1%) of these patients having readmissions for cardiac events for a total cost of readmissions of %149,686. 14 of 25 had a preoperative clearance by a cardiologist. In 19 of the 25 patients, the only preoperative cardiac screening tool performed was an electrocardiogram. Since instituting the new program, 842 additional surgeries were performed, 463 by the four surgeons involved. 126 patients were agreeable to be evaluated through the Preventive Cardio-Orthopaedics program. 4 patients of the four physicians still screened via the traditional cardiac program had a cardiac event readmission. The average readmission hospital stay was 3.33 days at a total cost of %42,321. 2 patients of the four physicians evaluated by the Preventive Cardio-Orthopaedics program had a cardiac related readmission, at an average hospital stay of 2 days, and at a total cost of %10,091. Conclusions. Risk sharing programs have forced surgeons to take a more active role in optimizing their patients medically; otherwise they will be penalized with a decreased reimbursement. Traditionally, we have abdicated this responsibility to primary care and cardiology physicians but have noted a high cardiac readmission risk. In response, we have begun using a unique cardiac screening model. Our preliminary experience predicts fewer cardiac readmissions thereby improving care, and at a lower cost

Introduction. Close to 30% of the surgical causes of readmission within 90 days post-total knee arthroplasty (TKA) and nearly half of those occurring in the first 2 years are caused by instability, arthrofibrosis, and malalignment, all of which may be addressed by improving knee balance. Furthermore, the recently launched Comprehensive Care for Joint Replacement (CJR) initiative mandates that any increase in post-acute care costs through 90-days post-discharge will come directly from the bundle payment paid to providers. Post-discharge costs, including the cost of readmissions for complications are one of the largest drivers of the 90-day cost of care. It is hypothesized that balanced knees post-TKA will lower the true provider costs within the 90-day bundle. Methods. Cost, outcomes and resource utilization data were collected from three independent surgeons pre- and post- adoption of intraoperative technology developed to provide real-time, quantitative load data within the knee. In addition, data were collected from Medicare claims, hospital records, electronic medical records (EMR), clinical, and specialty databases. The cohorts consisted of 932 patients in the pre-adoption group and 709 patients in the post-adoption group. These 2 groups were compared to the CMS national average data from 291,201 cases. The groups were controlled for age, sex, state, and BMI with no major differences between cohorts. The cost factors considered were the length of hospital stay, physician visits and physical therapy visits in addition to post-operative complications (e.g., manipulation under anesthesia (MUA) and aseptic revision). Results. After adoption of technology to improve ligament balancing intra-operatively, all three surgeons decreased their patients’ hospital stay (3.0 days to 2.6 days), number of physician visits (2.3 to 2.1), number of outpatient physical therapy visits (14.9 to 10.6) and MUA rate (2.3% to 1.8%). These clinical benefits subsequently lowered the 90-day net cost of TKA an average of $443 per case. When compared to the national average, this cost savings was $725 per case. Conclusions. Appropriately balancing TKA patients intra-operatively might help mitigate costs associated with TKA procedures within the 90-day bundle. In this study, it was found that using new joint balancing technology generated a substantial cost-savings post-discharge, primarily due to patients requiring less outpatient physical therapy

As the American population ages and a trend toward performing total hip arthroplasty (THA) in younger patients continues, the number of Americans undergoing THA is projected to increase over time. The advent of the bundled payment system combined with the current medical utilization climate has placed considerable pressure on surgeons to produce excellent results with early functional recovery and short hospital stays. The US obesity epidemic has transcended into the arthroplasty patient population and surgeons must assess whether obesity is a risk factor for poor outcomes in THA and determine how it should be managed. We performed a recent literature review to determine how obesity impacts outcomes in total hip arthroplasty and what must be done to improve outcomes in the obese arthroplasty patient. Our goal is to answer 3 questions: does obesity increase the complication rate in THA, if obesity matters how obese is too obese, and what must be done to improve outcomes in the obese patient?. Ultimately, obesity has been shown to correlate with increased post-operative complications in THA. The arthroplasty surgeon must optimise the obese patient prior to surgery by identifying associated comorbidities and consider malnutrition screening with counseling. Notice should be taken of the degree of obesity as patients with BMI > 40 have demonstrated much higher complication rates. Strong consideration should be given to avoiding direct anterior approach in the obese patient. Healthy weight loss must be encouraged with appropriate patient counseling and treatment in order to achieve success with THA in obese patients.  

Introduction. Alternative payment models, such as bundled payments, aim to control rising costs for total knee (TKA) and total hip arthroplasty (THA). Without risk adjustment for patients who may utilize more resources, concerns exist about patient selection and access to care. The purpose of this study was to determine whether lower socioeconomic status (SES) was associated with increased resource utilization following TKA and THA. Methods. Using the Michigan Arthroplasty Registry Collaborative Quality Initiative (MARCQI) database, we reviewed a consecutive series of 4,168 primary TKA and THA patients over a 3-year period. We defined lowest SES based upon the median household income of the patient's ZIP code. An a prioripower analysis was performed to determine the appropriate sample size. Demographics, medical comorbidities, length of stay, discharge destination, and readmission rates were compared between patients of lowest SES and higher SES. Results. Patients in the lowest SES group had a longer hospital length of stay (2.79 vs. 2.22 days, p<0.001), were more likely to be discharged to a rehabilitation facility (27% vs. 18%, p<0.001), and be readmitted to the hospital within 90 days (11% vs. 8%, p=0.002) than the higher SES group. In the multivariate analysis, lowest SES was found to be an independent risk factor for 90-day readmission rate (OR 1.50, 95% CI 1.15–1.96, p=0.003), extended hospital LOS 4 days or greater (OR 2.34, 95% CI 1.78–3.07, p<0.001), and discharge to a rehabilitation facility (OR 1.64, 95% CI 1.34–2.01, p<0.001). Both age greater than 75 years and obesity were also independent risk factors for all three outcome measures. Conclusion. Patients in the lowest SES group utilize more resources in the 90-day postoperative period. Therefore, risk adjustment models, including SES, may be necessary to fairly compensate hospitals and surgeons and to avoid potential problems with access to joint replacement care

Introduction. Hip and knee device sales representatives (reps) can provide intra-operative guidance through their knowledge of the products, especially in complicated cases such as revision hip and knee arthroplasty. However, for an experienced arthroplasty surgeon in the majority of straightforward primary cases, the rep's presence may not be required for clinical decision-makings. With recent challenges in cost savings and bundle payments, hospitals and surgeons have focused on reducing the implant costs, among others, with a “repless” model. The aim of this study was to describe the process of utilizing this model, assess its efficacy, and analyze the cost savings in primary hip arthroplasty. Methods. During the month of January 2016, 20 cases of primary, straightforward total hip arthroplasties were performed with the repless model by 2 experienced arthroplasty trained surgeons. All patients were followed prospectively for minimum 3 months. Prior to initiating the repless model, we focused on process management of the operating room with staff training and re-engineering of the trays to obtain a setup that included one hospital tray and one device company tray for each operation. The responsibilities of the rep were divided into 2 categories for better management:. Familiarity of the instruments, implant, and techniques; trays set up and assurance of availability of the implants. These responsibilities were covered by a trained OR technician and the surgeon. Final verification of the accurate implants prior to opening the packaging. This was done by a trained OR nurse and the surgeon. Results. We did not have any intra-operative complications. We also did not encounted any issued with the trays or errors in opening of the implants. There were no re-admissions, fracture, dislocation, or infection. The mean length of stay was 2.2 ± 0.5 days (range 1–3 days) with 68% home discharges. The cost of the implant was reduced from $4,800 to $1,895 with $2,905 cost saving per case and total savings of $58,100. The projected savings only for uncomplicated primary total hip arthroplasty (minimum 120 cases/year between 2 surgeons) is $384,600. Further cost saving from the process management changes were seen in central sterile processing time. Prior to the one tray system, the hospital had 3 in-house trays and there were 4 device company trays. We also noticed an approximate 27% improvement in turnover time. Conclusion. Repless model has significant cost saving potential. Preparation for the transition, proper patient selection, standardization of the trays and implants, and distribution of the responsibilities between OR nurses, technicians and the surgeon are essential

BACKGROUND. As the climate of medicine continues to change, physicians and healthcare administrations seek to improve both the quality of the care we provide patients, as well as reducing the cost at which we provide that care. Delivering value based care is of the utmost importance. The Perioperative Surgical Home (PSH) model is a multidisciplinary team approach to care that has shown success in reducing cost, length of stay, and admission to after care facilities. We sought to compare the results of total knee arthroplasty patients managed in the PSH rapid recovery model, to patients managed in a more traditional fashion. METHODS. We compared 451 patients managed in the PSH model from January 1 to December 31, 2015 to 453 patients managed in a more traditional fashion from January 1 to December 31, 2014. Preoperative. Once identified as potential candidates for total knee arthroplasty, a thorough triage process to optimize patients' medical co-morbidities, educate, and set expectations begins with an evaluation by the preoperative staff and mandatory attendance at a total joint class. Patients were sent for pre-operative physical therapy. Intraoperative. Neuraxial anesthesia was the anesthetic of choice, and perineural analgesia in the form of an adductor canal catheter and single shot posterior capsular injection were used to minimize pain and narcotic usage while maintaining the patient's ability to ambulate with physical therapy early in the post operative course. Additionally, multimodal analgesia was achieved with non- opioid analgesics (acetaminophen, NSAIDS, and gabapentanoids) and limited opioids. Aggressive fluid management and administration of steroids and ketamine also took place intraoperatively. Postoperatively. A multi-disciplinary team led by an orthopaedic surgeon and an anesthesiologist managed the patients throughout their stay. Multimodal analgesia was continued, and there was a rapid de-escalation of care. Physical therapy was initiated in PACU and continued at a minimum of BID thereafter. Patients were eligible for discharge on POD 1 after meeting physical therapy criteria. RESULTS. Average Length of Stay (LOS): 2.86 days in 2014 down to 2.1 in 2015 for an over 25% reduction. Discharge Mix: 71% to home independently or with home health in 2014 increased to 80% in 2015, with a reduction in discharges to a Skilled Nursing Facility from 24% to 16% respectively. 30 Day Readmissions: remained constant at 8 per year. Hospital Cost: $11,126.00 in 2014 vs $10,703.00 in 2015. CONCLUSION. As bundled payments began to change the financial climate of joint replacement surgery it is important to minimize costs and length of stay while continuing to improve care and outcomes. The PSH rapid recovery model delivers value based care that is well suited for this environment

Introduction. CMS is now publicly reporting 30-day readmission rates following total joint replacement (TJR) by hospital and is planning the collection of patient-reported function and pain after TJR. Nationally, 5% of patients are readmitted to the hospital after TJR for both medical and orthopedic-related issues. However, the relationship between readmission and functional gain and pain relief after TJR has not been evaluated. Methods. Clinical data on 2990 CMS patients from over 150 surgeons practicing in 22 US states who elected primary unilateral TJR in 2011–2012 were identified. Measures include pre-operative demographics, BMI, medical and musculoskeletal comorbidities, pain and function (KOOS/HOOS; SF36) and 6 month post-TJR pain and function. Data were merged with CMS claims to verify 30-day readmissions. Descriptive statistics and multivariate models adjusted for covariates and clustering within site were performed. Results. Overall 4.7% of patients were readmitted; 2.0% due to limb related diagnoses. Readmitted patients had significantly greater number of medical comorbidities; more severe OA in non-operated knees and hips; were more likely to smoke; and have poorer pre-TJR function (all p<0.05). After TJR, a greater proportion of readmitted patients had poor global function (PCS<30= 14% vs. 8%; p<0.008) but knee/hip function was similar in both groups. Joint pain improvement did not differ by readmit status. Conclusion. In this national representative cohort of CMS patients, patients readmitted within 30 days after TJR had poorer global function but similar joint specific function as non-readmitted patients. Readmitted patients also had significantly more medical comorbidities, more severe osteoarthritis in non-operated knees and hips; were more likely to smoke; and have poorer pre-TJR function. The overall rate of FORCE-TJR CMS patients readmitted within 30 days (4.7%) is consistent with national CMS analyses (5%). Of interest, in our cohort, readmitted patients had poorer global function after surgery, but similar joint specific (hip/knee) function compared to patients who were not readmitted. They also had poorer pre-THR function, and more severe OA in other joints, which may contribute to their overall lower global function scores. As CMS moves to use PROs in its bundled payment, these data support the importance of hip/knee-specific PRO measures to assess THR outcomes in quality of care programs and CMS reporting programs

Several design principles were considered paramount when the surgical technique of performing total hip arthroplasty through an incision in the superior capsule without dislocation of the hip joint was developed. These design principles include: Preservation of the abductors; Preservation of the posterior capsule and short external rotators; Preparation of the femur in situ without dislocation of the hip; In-line access to the femoral shaft axis; Ability to perform a trial reduction; Independence from intraoperative imaging; Independence from a traction table; Applicable to at least 99% of THA procedures. Personal experience with more than 1950 THA using the superior capsulotomy technique over a 12-year period has demonstrated several observations: Dislocation rate of 0.15% (3 in 1950); Acute deep infection rate of 0% (0 in 1950); Universal applicability: used in 99.7% of primary THA; Lateral femoral cutaneous nerve palsy incidence: 0/1950; Femoral nerve palsy incidence: 0/1950; Transient peroneal palsy incidence: 2/1950; Length of stay (since 2010): 1.55 days; Discharge to home: 98%; 90-day cost (2/13 to 2/14) compared to other exposures in CMS patients in the same institution: $24,200 vs $30,100; Readmission costs (CMS 2/13 to 2/14) at 90 days: $0. Conclusion: Performing total hip arthroplasty without dislocation and with preservation of the abductors, posterior capsule and short external rotations has proven to have a low dislocation rate, a low infection rate, and wide applicability. CMS 12-month expenditure data documenting ZERO dollars spent on readmission for any reason within 90 days of surgery demonstrates the potential for simultaneously improving incomes and reducing cost, with particular benefit within the CMS BPCI and private bundled payment programs

Numerous studies have shown highly cross-linked polyethylene (XLPE) to be an extremely low wear bearing surface for total hip arthroplasty (THA) at intermediate term follow-up. Wear rates and the incidence of osteolysis for CoCr femoral heads on XLPE liners appears to be considerably less than what is observed for conventional polyethylene (PE). This has been demonstrated even in younger, more active patients. Nevertheless, polyethylene wear and associated osteolysis are still a concern, since the indications for THA have been expanded to include younger and more active patients. Both wear simulator and clinical data suggest that ceramic femoral heads can reduce bearing surface wear of conventional PE. There is, however, extremely limited evidence supporting any advantage of ceramic femoral heads over CoCr femoral heads with regards to bearing surface wear of XLPE. This is perhaps due to the relative difficulty in measuring the low wear rates of XLPE bearings in general, regardless of material composition of the femoral head. Although ceramic femoral heads are more scratch resistant and less susceptible to third body wear, their current clinical use to reduce wear of XLPE bearings is, in reality, based on the unproven assumption that use of ceramic femoral heads will have a similar effect on wear reduction as is seen with ceramic on conventional PE bearing couples. Nevertheless, the use of ceramic femoral heads has become common in younger, more active patients. Recently, corrosion at the head neck junction of modular THA (trunnionosis), has been determined to be the possible source of metal debris and metal ions associated with adverse local tissue reactions (ALTR or ARMD) in THA, including ALVAL and pseudotumors. There is general agreement that trunnionosis results from mechanically assisted crevice corrosion (fretting) of the modular junctions common to nearly all contemporary THA designs. Several design, material and patient factors have been implicated as contributors to this problem including larger diameter femoral heads (>36 mm), reduced femoral neck and taper geometry, flexural rigidity of the taper, and patient body weight and activity level. Data from our multicenter implant retrieval program has shown that corrosion at the head-neck junction of contemporary modular THAs may be reduced with use of ceramic femoral heads. The use of ceramic femoral heads also eliminates the potential for release of cobalt and chromium ions from the taper junctions of titanium alloy stems. In younger patients, the long term effects of cobalt ions released from corrosion at the modular neck junction are still unknown. Although the surgeon's selection of a ceramic femoral head in combination with a XLPE acetabular liner is likely based on the desire to minimise PE wear, the impact of femoral head composition on taper neck corrosion and ALTR is perhaps more of a concern in 2015. Until the problem of taper neck corrosion is more thoroughly understood and effectively addressed by implant manufacturers, the use of ceramic femoral heads in THA should be considered in the younger or more active patient. The increased cost of ceramic femoral heads creates a dilemma in defining who is “young” enough and “active” enough to be considered an appropriate candidate for a ceramic femoral head in our current environment of bundled care payments, value based purchasing and concern about providing cost-effective health care to our patients

Aims

Medical comorbidities are a critical factor in the decision-making process for operative management and risk-stratification. The Hierarchical Condition Categories (HCC) risk adjustment model is a powerful measure of illness severity for patients treated by surgeons. The HCC is utilized by Medicare to predict medical expenditure risk and to reimburse physicians accordingly. HCC weighs comorbidities differently to calculate risk. This study determines the prevalence of medical comorbidities and the average HCC score in Medicare patients being evaluated by neurosurgeons and orthopaedic surgeon, as well as a subset of academic spine surgeons within both specialities, in the USA.
