Background
The Centers for Medicare and Medicaid Services (CMS) are implementing changes in hospital reimbursement models for total joint arthroplasty (TJA), moving to value-based bundled payments from the fee-for-service model. The purpose of this study is to identify consults and complications during the perioperative period that increase financial burden.Methods
We combined CMS payment data for inpatient, professional, and postoperative with retrospective review of patients undergoing primary TJA and developed profiles of patients included in the Comprehensive Care for Joint Replacement bundle undergoing TJA. Statistical comparison of episode inpatient events and payments was conducted. Multiple regression analysis was adjusted for length of stay, disposition, and Charlson-Deyo comorbidity profile.Results
Median total payment was $21,577.36, which exceeded the median bundle target payment of $20,625.00. Adjusted analyses showed that psychiatry consults (increase of $73,123.32; P < .001), internal medicine consults ($5789.38; P ≤ .001), pulmonary embolism ($35,273.68; P < .001), intensive care unit admission ($14,078.37; P < .001), and deep vein thrombosis ($9471.26; P = .019) resulted in increased payments using multivariate analysis adjusted for length of stay, Charlson-Deyo comorbidities, and discharge disposition.Conclusion
Patients with inpatient complications such as pulmonary embolism and/or deep vein thrombosis, intensive care unit admission, and medical/psychiatric consultation exceeded the CMS target. Although study results showed typical complication rates, acute inpatient consultation significantly increased utilization beyond the CMS target even when adjusted for length of stay, patient comorbidities, and discharge. Needed medical care should continue to be a priority for inpatients, and allowance for individual outliers should be considered in policy discussions. 相似文献2.

Background
The Centers for Medicare & Medicaid Services (CMS) recently imposed penalties against hospitals with above-average 30-day readmission rates following total joint arthroplasty (TJA). Hospitals must decide whether investments in readmission prevention are worthwhile. This study examines the financial incentives associated with unplanned readmissions before and after invocation of these penalties.Methods
Financial data were reviewed for 2028 consecutive primary TJAs performed on Medicare beneficiaries over a 2-year period at an urban academic health system. Readmission penalties were estimated in accordance with CMS policies.Results
Unplanned readmissions generated a $4416 median contribution margin. The initial hospitalizations (when the TJA was performed) were financially unfavorable for patients subsequently readmitted relative to those not readmitted due to increased costs of care (P = .002), but these costs were more than outweighed by the increased reimbursement earned during the readmission (P < .001), ultimately making readmitted patients financially preferable (P < .001). Going forward, penalties will be levied for risk-adjusted readmission rates above the national rate of 4.8%. For the institution under review, the penalty per readmission outweighs the financial gains earned through readmission by $12,184, resulting in a net loss from readmissions if the rate exceeds 6.5%. It will be financially optimal to maintain a readmission rate (after risk adjustment) equal to the national average but exceeding that rate will be $7768 more expensive per readmission than undershooting that target.Conclusion
If our results are generalizable, unplanned Medicare readmissions have traditionally been financially beneficial, but CMS penalties outweigh this benefit. Thus, penalties should incentivize institutions to maintain below-average arthroplasty readmissions rates. 相似文献3.

Background
Due to concerns about higher complication rates, surgeons debate whether to perform simultaneous bilateral total joint arthroplasty (BTJA), particularly in the higher-risk Medicare population. Advances in pain management and rehabilitation protocols have called into question older studies that found an overall cost benefit for simultaneous procedures. The purpose of this study was to compare 90-day episode-of-care costs between staged and simultaneous BTJA among Medicare beneficiaries.Methods
We retrospectively reviewed a consecutive series of 319 simultaneous primary TJAs and 168 staged TJAs (336 procedures) at our institution between 2015 and 2016. We recorded demographics, comorbidities, readmission rates, and 90-day episode-of-care costs based upon Centers for Medicare and Medicaid Services claims data. To control for confounding variables, we performed a multivariate regression analysis to identify independent risk factors for increased costs.Results
Simultaneous patients had decreased inpatient facility costs ($19,402 vs $23,025, P < .001), increased post-acute care costs ($13,203 vs $10,115, P < .001), and no difference in total episode-of-care costs ($35,666 vs $37,238, P = .541). Although there was no difference in readmissions (8% vs 9%, P = .961), simultaneous bilateral patients were more likely to experience a thromboembolic event (2% vs 0%, P = .003). When controlling for demographics, procedure, and comorbidities, a simultaneous surgery was not associated with an increase in episode-of-care costs (P = .544). Independent risk factors for increased episode-of-care costs following BTJA included age ($394 per year increase, P < .001), cardiac disease ($4877, P = .025), history of stroke ($14,295, P = .010), and liver disease ($12,515, P = .016).Conclusion
In the Medicare population, there is no difference in 90-day episode-of-care costs between simultaneous and staged BTJA. Surgeons should use caution in performing a simultaneous procedure on older patients or those with a history of stroke, cardiac, or liver disease. 相似文献4.

Background
Although some bundled payment models have had success in total joint arthroplasty, concerns exist about access to care for higher cost patients who use more resources. The purpose of this study is to determine whether Medicaid patients have increased hospital costs and more resource utilization in a 90-day episode of care than Medicare or privately insured patients.Methods
We retrospectively reviewed a consecutive series of 7268 primary hip and knee arthroplasty patients at a single institution. Using a propensity score-matching algorithm for demographic variables, we matched the 92 consecutive Medicaid patients with 184 privately insured and 184 Medicare patients. Hospital-specific costs, discharge disposition, complications, and 90-day readmissions were analyzed.Results
Medicaid patients had higher mean inpatient hospital costs than both of the matched Medicare and privately insured groups ($15,396 vs $12,165 vs $13,864, P < .001) with longer length of stay (3.34 vs 2.49 vs 1.46 days, P < .001). Medicaid and Medicare patients were more likely to be discharged to a rehabilitation facility than privately insured patients (17% vs 21% vs 1%, P < .001). When controlling for demographic factors and comorbidities, Medicaid insurance was a significant independent risk factor for increased hospital costs (odds ratio 3.64, 95% confidence interval 1.80-7.38, P < .001).Conclusion
Because of increased hospital costs, current bundled payment models should not include Medicaid patients because of concerns about patient selection and access to care. Further study is needed to determine whether bundling Medicaid arthroplasty costs in a stand-alone program with a separate target price will result in improved outcomes and decreased costs. 相似文献5.

Background
The benefits of discharge to a skilled nursing facility (SNF) in Medicare-eligible patients after total joint arthroplasty (TJA) have recently been scrutinized. The purpose of this study was to determine short-term complication and readmission rates for SNF versus home discharge in patients eligible for Medicare and SNF discharge.Methods
Patients who underwent TJA between 2012 and 2013 were identified in the National Surgical Quality Improvement Project database. Patients over 65 years and who discharged at or after postoperative day 3, and thus SNF eligible by Medicare rule, were included. Patient demographics and comorbidities were compared in the 2 cohorts (home versus SNF), and subsequent univariate and multivariate analyses were used to determine risk factors for short-term complications.Results
We identified 34,610 Medicare- and SNF-eligible TJA patients; 54.8% discharged home. Patients with SNF discharge were older, had higher rates of comorbidities, and were more frequently American Society of Anesthesiologists class 3 or 4 (P < .001). Univariate analysis revealed that patients with SNF discharge had higher rates of any complication (7.9% vs. 4.7%, P < .001) and readmission (5.3% vs. 3.3%, P < .001). Multivariate regression analysis identified SNF discharge (adjusted odds ratio 1.9, 95% confidence interval 1.7-2.0) as an independent risk factor for a 30-day complication and readmission.Conclusions
In a cohort of Medicare- and SNF-eligible patients, SNF discharge was the strongest predictor of 30-day complication after TJA. SNF discharge was also an independent predictor of readmission after TJA. 相似文献6.
Background
As early implementors of the Centers for Medicare and Medicaid Services (CMS) Bundled Payments for Care Improvement (BPCI) initiative, our private practice sought to compare our readmission rates, post-acute care utilization, and length of stay for the first year under BPCI compared to baseline data.Methods
We used CMS data to compare total expenditures of all diagnosis-related groups (DRGs). Medicare patients who underwent orthopedic surgery between 2009 and 2012 were defined as non-BPCI (n = 8415) and were compared to Medicare BPCI patients (n = 4757) who had surgery in 2015. Ninety-day post-acute events including inpatient rehabilitation facility or subacute nursing facility admission, home health (HH), and readmissions were analyzed.Results
The median expenditure for non-BPCI patients was $22,193 compared to $19,476 for BPCI patients (P < .001). Median post-acute care spend was $6861 for non-BPCI and $5360 for BPCI patients (P < .001). Compared to non-BPCI patients, BPCI patients had a lower rate of subacute nursing facility admissions (non-BPCI 43% vs 37% BPCI; P < .001), inpatient rehabilitation facility admissions (non-BPCI 3% vs 4% BPCI; P = .005), HH (non-BPCI 79% vs 73% BPCI; P < .001), and readmissions (non-BPCI 12% vs 10% BPCI; P = .02). Changes in length of stay for post-acute care were only significant for HH with BPCI patients using a median 12 days and non-BPCI using 24 days.Conclusion
The objective of BPCI was to improve healthcare value. Through substantial efforts both financially and utilization of human resources to contain costs with clinical practice guidelines, patient navigators, and a BPCI management team, the expenditures for CMS were significantly lower for BPCI patients. 相似文献7.

Background
The purpose of this study is to analyze whether the cost for ceramic-on-polyethylene (C-PE) and ceramic-on-ceramic (COC) bearings used in primary total hip arthroplasty (THA) was changing over time, and if the cost differential between ceramic bearings and metal-on-polyethylene (M-PE) bearings was approaching the previously published tipping point for cost-effectiveness of $325.Methods
A total of 245,077 elderly Medicare patients (65+) who underwent primary THA between 2010 and 2015 were identified from the United States Medicare 100% national administrative hospital claims database. The inpatient hospital cost, calculated using cost-to-charge ratios, and hospital payment were analyzed. The differential cost of C-PE and COC bearings, compared to M-PE, were evaluated using parametric and nonparametric models.Results
After adjustment for patient and clinical factors, and the year of surgery, the mean hospital cost and payments for primary THA with a C-PE or COC was within ±1% of the cost for primary THA with M-PE bearings (P < .001). From the nonparametric analysis, the median hospital cost was $318-$360 more for C-PE and COC than M-PE. The differential in median Medicare payment for THA with ceramic bearings compared to M-PE was <$100. Cost differentials were found to decrease significantly over time (P < .001).Conclusion
Patient and clinical factors had a far greater impact on the cost of inpatient THA surgery than bearing selection. Because we found that costs and cost differentials for ceramic bearings were decreasing over time, and approaching the tipping point, it is likely that the cost-effectiveness thresholds relative to M-PE are likewise changing over time and should be revisited in light of this study. 相似文献8.
Background
Limited data describe risks and perioperative resource needs of total joint arthroplasty (TJA) in dialysis-dependent patients.Methods
Retrospective multiple cohort analysis of dialysis-dependent American College of Surgeons National Surgical Quality Improvement Program patients undergoing primary elective total hip and knee arthroplasty compared to non–dialysis-dependent controls from 2005 to 2015. Relative risks (RRs) of 30-day adverse events were determined by multivariate regression adjusting for baseline differences.Results
Six hundred forty-five (0.2%) dialysis-dependent patients of 342,730 TJA patients were dialysis-dependent and more likely to be dependent, under weight, anemic, hypoalbuminemic, and have cardiopulmonary disease. In total hip arthroplasty patients, dialysis was associated with greater risk of any adverse event (RR = 1.1, P < .001), mortality (RR = 2.8, P = .012), intensive care unit (ICU) care (RR = 9.8, P < .001), discharge to facility (RR = 1.3, P < .001), and longer admission (1.5×, P < .001). In total knee arthroplasty patients, dialysis conferred greater risk of any adverse event (RR = 1.1, P < .001), ICU care (RR = 6.0, P < .001), stroke (RR = 7.6, P < .001), cardiac arrest (RR = 4.8, P = .014), discharge to facility (RR = 1.5, P < .001), readmission (RR = 1.8, P = .002), and longer admission (1.3×, P < .001).Conclusion
Dialysis-dependence is an independent risk factor for 30-day adverse events, ICU care, longer admission, and rehabilitation needs in TJA patients. Thirty days is not sufficient to detect infectious complications among these patients. These findings inform shared decision-making, perioperative resource planning, and risk adjustment under alternative reimbursement models. 相似文献9.

Background
As outpatient total hip (THA) and knee arthroplasties (TKA) increase in popularity, concerns exist about the safety of discharging patients home the same day. The purpose of this study is to determine the complications associated with outpatient total joint arthroplasty (TJA) and to identify high-risk patients who should be excluded from these protocols.Methods
We queried the American College of Surgeons-National Surgical Quality Improvement Program database for all patients who underwent primary TKA or THA from 2011 to 2014. Demographic variables, medical comorbidities, and 30-day complication, readmission, and reoperation rates were compared between outpatient and traditional inpatient procedures. A multivariate logistic regression analysis was then performed to identify independent risk factors of poor short-term outcomes.Results
Of the total 169,406 patients who underwent TJA, 1220 were outpatient (0.7%). The outpatient and inpatient groups had an overall complication rate of 8% and 16%, respectively. Patients aged more than 70 years, those with malnutrition, cardiac history, smoking history, or diabetes mellitus are at higher risk for readmission and complications after THA and TKA (all P < .05). Surprisingly, outpatient TJA alone did not increase the risk of readmission (OR 0.652, 95% CI 0.243-1.746, P = .395) or reoperation (OR 1.168, 95% CI 0.374-3.651, P = .789), and was a negative independent risk factor for complications (OR 0.459, 95% CI 0.371-0.567, P < .001).Conclusion
With the resources available in a hospital setting, outpatient TJA may be a safe option, but only in select, healthier patients. Care should be taken to extrapolate these results to an outpatient facility, where complications may be more difficult to manage. 相似文献10.

Background
As the prevalence of and life expectancy after solid organ transplantation increases, some of these patients will require total hip arthroplasty (THA). Immunosuppressive therapy, metabolic disorders, and post-transplant medications may place transplant patients at higher risk of adverse events following surgery. The objective of this study was to compare inpatient complications, mortality, length of stay (LOS), and costs for THA patients with and without solid organ transplant history.Methods
A retrospective cross-sectional analysis was conducted using 1998-2011 Nationwide Inpatient Sample. Primary THA patients were queried (n = 3,175,456). After exclusions, remaining patients were assigned to transplant (n = 7558) or non-transplant groups (n = 2,772,943). After propensity score matching, adjusted for patient and hospital characteristics, logistic regression and paired t-tests examined the effect of transplant history on outcomes.Results
Between 1998 and 2011, THA volume among transplant patients grew approximately 48%. The overall prevalence of one or more complications following THA was greater in the transplant group than in the non-transplant group (32.0% vs 22.1%; P < .001). In-hospital mortality was minimal, with comparable rates (0.1%) in both groups (P = .93). Unadjusted trends show that transplant patients have greater annual and overall mean LOS (4.47 days) and mean admission costs ($18,402) than non-transplant patients (3.73 days; $16,899; P < .001). After propensity score matching, transplant history was associated with increased complication risk (odds ratio, 1.56) after THA, longer hospital LOS (+0.64 days; P < .001), and increased admission costs (+$887; P = .005).Conclusion
Transplant patients exhibited increased odds of inpatient complications, longer LOS, and greater admission costs after THA compared with non-transplant patients. 相似文献11.

Background
As alternative payment models increase in popularity for total joint arthroplasty (TJA), providers and hospitals now share the financial risk associated with unexpected readmissions. While studies have identified postacute care as a driver for costs in a bundle, the fiscal burden associated with specific causes of readmission is unclear. The purpose of this study is to quantify the additional costs associated with each of the causes of readmission following primary TJA.Methods
We reviewed a consecutive series of primary TJA patients at our institution from 2015 to 2016 using claims data from the Centers for Medicare and Medicaid Services and Medicare Advantage patients from a single private insurer. We collected demographic data, medical comorbidities, 90-day episode-of-care costs, and readmissions for all patients. Medical records for each readmission were reviewed and classified into 1 of 11 categories. We then compared the mean facility readmission costs, postacute care costs, and overall 90-day episode-of-care costs between the reasons for readmission.Results
Of the 4704 patients, there were 325 readmissions in 286 patients (6.1%), with 50% being readmitted to a different facility than their index surgery hospital. The mean additional cost was $8588 per readmission. Medical reasons accounted for the majority of readmissions (n = 257, 79.1%). However, patients readmitted for revision surgery (n = 68, 20.9%) had the highest mean readmission cost ($15,356, P < .001). Furthermore, readmissions for revision surgery had the highest mean postacute care ($37,207, P = .002) and overall episode-of-care costs ($52,162, P = .003). Risk factors for readmission included age >75 years (odds ratio [OR], 1.85; P < .001), body mass index >35 kg/m2 (OR, 1.63; P = .004), history of congestive heart failure (OR, 2.47; P = .002), diabetes mellitus (OR, 2.0; P < .001), and renal disease (OR, 2.28; P = .005).Conclusion
Providers participating in alternative payment models should be cognizant of the increased bundle costs attributed to readmissions, especially due to revision surgery. Improved communication with patients and close postoperative monitoring may help minimize the large percentage of readmissions at different facilities. 相似文献12.

Background
Despite efforts to curtail the economic burden of total joint arthroplasty (TJA), utilization of these successful procedures continues to increase. Previous studies have provided evidence for pent-up demand (delaying necessary medical care until financially feasible) in health care as insurance status changes. We sought to determine whether evidence exists for pent-up demand in the TJA population when patients become eligible for Medicare enrollment.Methods
The 2014 Nationwide Readmission Database was used to determine the incidence of TJA. The observed increase in incidence from age 64 to 65 was compared to the expected increase. Pent-up demand was calculated by subtracting the expected from the observed difference in frequency of TJA, and excess cost was determined by multiplying this value by the median cost of a primary TJA. The Medicare Expenditure Panel Survey Household Component was used to compare out-of-pocket (OOP) costs, access to care, and insurance coverage among patients aged 60-64 (group 1) and 66-70 (group 2).Results
The expected and observed increases in TJA procedures from age 64 to 65 were 595 and 5211, respectively, resulting in pent-up demand of 4616 joint arthroplasties (1273 THA and 3343 TKA), and an excess cost of $55 million (range, $33 million-$70 million). Mean total OOP expenses for patients in group 1 were significantly greater ($1578.39) than patients in group 2 ($1143.63, P < .001). Despite spending more money OOP, the proportion of patients who were unable to obtain necessary medical care was significantly higher in group 1 than group 2 (4.9% vs 2.4%, P < .0001). This discrepancy was most prominent among patients with public insurance (10.6% vs 2.5%, P < .0001).Conclusion
The findings of this study suggest that patients with hip and knee osteoarthritis likely delay elective TJA until they are eligible for Medicare enrollment, resulting in significant additional financial burden to the public health system. As the population ages, it will become increasingly important for stakeholders and policy-makers to be aware of this pent-up demand for TJA procedures.Level of Evidence

Background
Readmission among Medicare recipients is a leading driver of healthcare expenditure. To date, most predictive tools are too coarse for direct clinical application. Our objective in this study is to determine if a pre-existing tool to identify patients at increased risk for inpatient falls, the Hendrich Fall Risk Score, could be used to accurately identify Medicare patients at increased risk for readmission following arthroplasty, regardless of whether the readmission was due to a fall.Methods
This study is a retrospective cohort study. We identified 2437 Medicare patients who underwent a primary elective total joint arthroplasty (TJA) of the hip or knee for osteoarthritis between 2011 and 2014. The Hendrich Fall Risk score was recorded for each patient preoperatively and postoperatively. Our main outcome measure was hospital readmission within 30 days of discharge.Results
Of 2437 eligible TJA recipients, there were 226 (9.3%) patients who had a score ≥6. These patients were more likely to have an unplanned readmission (unadjusted odds ratio 2.84, 95% confidence interval 1.70-4.76, P < .0001), were more likely to have a length of stay >3 days (49.6% vs 36.6%, P = .0001), and were less likely to be sent home after discharge (20.8% vs 35.8%, P < .0001). The effect of a score ≥6 on readmission remained significant (adjusted odds ratio 2.44, 95% confidence interval 1.44-4.13, P = .0009) after controlling for age, paralysis, and the presence of a major psychiatric disorder.Conclusion
Increased Hendrich fall risk score after TJA is strongly associated with unplanned readmission. Application of this tool will allow hospitals to identify these patients and plan their discharge. 相似文献14.

Background
Total joint arthroplasty (TJA) accounts for more Medicare expenditure than any other inpatient procedure. The Comprehensive Care for Joint Replacement model was introduced to decrease cost and improve quality in TJA. The largest portion of episode-of-care costs occurs after discharge. This study sought to quantify the cost variation of primary total hip arthroplasty (THA) according to discharge disposition.Methods
The Medicare and Humana claims databases were used to extract charges and reimbursements to compare day-of-surgery and 91-day postoperative costs simulating episode-of-care reimbursements. Of the patients who underwent primary THA, 257,120 were identified (204,912 from Medicare and 52,208 from Humana). Patients were stratified by discharge disposition: home with home health, skilled nursing facility, or inpatient rehabilitation facility.Results
There is a significant difference in the episode-of-care costs according to discharge disposition, with discharge to an inpatient rehabilitation facility the most costly and discharge to home the least costly.Conclusion
Postdischarge costs represent a sizeable portion of the overall expense in THA, and optimizing patients to allow safe discharge to home may help reduce the cost of THA. 相似文献15.

Background
The Comprehensive Care for Joint Replacement model is the newest iteration of the bundled payment methodology introduced by the Centers for Medicare and Medicaid Services. Comprehensive Care for Joint Replacement model, while incentivizing providers to deliver care at a lower cost, does not incorporate any patient-level risk stratification. Our study evaluated the impact of specific medical co-morbidities on the cost of care in total joint arthroplasty (TJA) patients.Methods
A retrospective study was conducted on 1258 Medicare patients who underwent primary elective TJA between January 2015 and July 2016 at a single institution. There were 488 males, 552 hips, and the mean age was 71 years. Cost data were obtained from the Centers for Medicare and Medicaid Services. Co-morbidity information was obtained from a manual review of patient records. Fourteen co-morbidities were included in our final multiple linear regression models.Results
The regression models significantly predicted cost variation (P < .001). For index hospital costs, a history of cardiac arrhythmias (P < .001), valvular heart disease (P = .014), and anemia (P = .020) significantly increased costs. For post-acute care costs, a history of neurological conditions like Parkinson’s disease or seizures (P < .001), malignancy (P = .001), hypertension (P = .012), depression (P = .014), and hypothyroidism (P = .044) were associated with increases in cost. Similarly, for total episode cost, a history of neurological conditions (P < .001), hypertension (P = .012), malignancy (P = .023), and diabetes (P = .029) were predictors for increased costs.Conclusion
The cost of care in primary elective TJA increases with greater patient co-morbidity. Our data provide insight into the relative impact of specific medical conditions on cost of care and may be used in risk stratification in future reimbursement methodologies. 相似文献16.

Background
Length of hospital stay (LOS) is a large driver of cost after primary total joint arthroplasty (TJA). Strategies to decrease LOS may help reduce the economic burden of TJA. This study's aim was to investigate the effect of day of the week of surgery on mean LOS and total charges following primary total knee arthroplasty (TKA) and total hip arthroplasty (THA).Methods
An administrative clinical database at a large US health care system was reviewed for all primary THA and TKA admissions performed between 2010 and 2012 (n = 15,237). Of these, 14,800 cases met our inclusion criteria and were analyzed. Furthermore, the cohort was divided into early (Monday/Tuesday) and late week (Thursday/Friday) surgeries, excluding Wednesday surgeries (n = 2835). Univariate and multiple regression analyses examined the effect of each variable on LOS.Results
Mean LOS for THA and TKA on Monday was 3.54 and 3.35 days and increased to 4.12 and 3.66 days on Friday (P < .0001), respectively. Late vs early week admissions had 0.358 (95% confidence interval: 0.29-0.425, P < .001) additional hospital days. Increased age (0.003 days per unit increase in age, P = .02) and severity of illness score (0.781 days per level increase, P < .001) were associated with increased LOS. Late week surgery had a greater effect on LOS for TKA than for THA. TKAs were associated with higher charges for late week surgery vs early week surgery (P < .001).Conclusion
Late week TJA cases, older age, and increasing severity of illness score were associated with increased LOS. Furthermore, late week TKA was associated with increased total charges. 相似文献17.

Background
The purpose of this study was to compare risks for revision and short-term complications after total joint arthroplasty (TJA) in matched cohorts of morbidly obese patients, receiving and not receiving prior bariatric surgery.Methods
Patients undergoing elective TJA between 1997 and 2011 were identified in a New York Statewide database, analyzing total knee arthroplasty (TKA) and total hip arthroplasty (THA) separately. Propensity scores were used to match morbidly obese patients receiving and not receiving bariatric surgery prior to TJA. Cox proportional hazard modeling assessed revision risk. Logistic regression evaluated odds for complications.Results
For TKA, 2636 bariatric surgery patients were matched to 2636 morbidly obese patients. For THA, 792 bariatric surgery patients were matched to 792 morbidly obese patients. Matching balanced all covariates. Bariatric surgery reduced co-morbidities prior to TJA (TKA P < .0001; THA P < .005). Risks for in-hospital complications were lower for THA and TKA patients receiving prior bariatric surgery (odds ratio [OR] 0.25, P < .001; and OR = 0.69, P = .021, respectively). Risks for 90-day complications were lower for TKA (OR 0.61, P = .002). Revision risks were not different for either THA (P = .634) or TKA (P = .431), nor was THA dislocation risk (P = 1.000).Conclusion
After accounting for relevant selection biases, bariatric surgery prior to TJA was associated with reduced co-morbidity burden at the time of TJA and with reduced post-TJA complications. However, bariatric surgery did not reduce the risk for revision surgery for either TKA or THA. 相似文献18.

Background
The 72-hour Medicare mandate (3-night stay rule) requires a 3-day inpatient stay for patients discharging to skilled nursing facilities (SNFs). Studies show that 48%-64% of Medicare total joint arthroplasty (TJA) patients are safe for discharge to SNFs on postoperative day (POD) #2. The purpose of this study was to extrapolate the financial impact of the 3-night stay rule.Methods
The American College of Surgeons National Surgical Quality Improvement Program database was queried for all primary TJAs performed in 2015. Discharge destination was recorded. Institutional cost accounting examined costs for patients discharging on POD #2 vs POD #3.Results
A total of 42,423 TJAs (14,395 total hip arthroplasties [THAs] and 28,028 total knee arthroplasties [TKAs]) were performed in patients over the age of 65 years. Of these patients, 5252 THAs (36.5%) and 12,022 TKAs (42.9%) were discharged from the hospital on POD #3, with 2404 THAs (16.7%) and 5083 TKAs (18.1%) being discharged to SNFs. Institutional cost accounting revealed hospital costs for THA were $2014 more, whereas hospital costs for TKA were $1814 more for a 3-day length of stay when compared with a 2-day length of stay (P < .001). The mean charge per day for an SNF was $486.Conclusion
The National Surgical Quality Improvement Program database is a representative sample of all surgeries performed in the United States. Extrapolating our findings to all Medicare TJAs nationally gives an estimated $63 million in annual savings. Medicare mandated, but potentially medically unnecessary inpatient days at a higher level of care increase the total cost for TJAs. Policies regarding minimum stay requirements before discharge should be re-evaluated. 相似文献19.

Background
The Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey, created by the Centers for Medicare and Medicaid, is directly tied to hospital reimbursement. The purpose of this study is to identify factors that are predictive HCAHPS survey responses following primary hip and knee arthroplasty.Methods
Prospectively collected HCAHPS responses from patients undergoing elective hip and knee arthroplasty between January 2013 and October 2017 at our institution were analyzed. Patient age, gender, race, marital status, body mass index, American Society of Anesthesiologists score, preoperative pain score, smoking status, alcohol use, illegal drug use, socioeconomic quartile, insurance type, procedure type, hospital type (academic vs community), distance to medical center, length of stay (LOS), and discharge disposition were obtained and correlated with HCAHPS inpatient satisfaction scores.Results
Responses from 3593 patients were obtained: 1546 total hip arthroplasties, 1899 total knee arthroplasties, and 148 unicompartmental knee arthroplasties. Mean overall HCAHPS score was 79.2. Women had lower inpatient satisfaction than men (77.6 vs 81.6, P < .001). Alcohol consumers had lower inpatient satisfaction than abstainers (77.7 vs 81.6, P < .001). Inpatient satisfaction varied by socioeconomic quartile (P < .001) with patients in the highest quartile having lower satisfaction than patients in all other quartiles (P < .001). Patients discharged to a facility had lower inpatient satisfaction than those discharged home (71.2 vs 80.2, P < .001). An inverse correlation between inpatient satisfaction and LOS (r = ?0.19, P < .001) and a direct correlation between satisfaction and distance to medical center (r = 0.06, P < .001) were seen.Conclusion
Patients more likely to report lower levels of inpatient satisfaction after total joint arthroplasty are female, affluent, and alcohol consumers, who are discharged to postacute care facilities. Inpatient satisfaction was inversely correlated with LOS and positively correlated with distance from patient home to medical center. These findings provide targets for improvements in TJA inpatient care. 相似文献20.
