Background
Recent healthcare reform efforts have focused on improving the quality of total joint replacement care while reducing overall costs. The purpose of this study is to determine if higher volume centers have lower costs and better outcomes than lower volume hospitals.Methods
We queried the Centers for Medicare and Medicaid Services (CMS) Inpatient Charge Data and identified 2702 hospitals that performed a total of 458,259 primary arthroplasty procedures in 2014. Centers were defined as low (performing <100 total joint arthroplasty [TJA] per year) or high volume and mean total hospital-specific charges and inpatient payments were obtained. Patient satisfaction scores as well 30-day risk-adjusted complication and readmission scores were obtained from the multiyear CMS Hospital Compare database.Results
Of all the hospitals, 1263 (47%) hospitals were classified as low volume and performed 60,895 (12%) TJA cases. Higher volume hospitals had lower mean total hospital-specific charges ($56,323 vs $60,950, P < .001) and mean Medicare inpatient payments ($12,131 vs $13,289, P < .001). Higher volume facilities had a lower complication score (2.96 vs 3.16, P = .015), and a better CMS hospital star rating (3.14 vs 2.89, P < .001). When controlling for hospital geographic and demographic factors, lower volume hospitals are more likely to be in the upper quartile of inpatient Medicare costs (odds ratio 2.127, 95% confidence interval 1.726-2.621, P < .001).Conclusion
Hospitals that perform <100 TJA cases per year may benefit from adopting the practices of higher volume centers in order to improve quality and reduce costs. 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
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4.
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5.

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6.

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7.

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8.

Background
Bundled payment programs for primary total joint arthroplasty (TJA) have identified reducing nonhome discharge as a major area of cost savings. Health care providers must therefore identify, risk stratify, and appropriately care for home-discharged TJA patients. This study aimed to analyze risk factors and timing of postdischarge complications among home-discharged primary total hip arthroplasty (THA) and total knee arthroplasty (TKA) patients and risk stratify them to identify those who would benefit from higher level care.Methods
Patients discharged home after elective primary THA/TKA from 2011 to 2014 were identified in the National Surgical Quality Improvement Program database. Bivariate and multivariate analyses were performed using perioperative variables.Results
A total of 50,376 and 71,293 home-discharged THA and TKA patients were included for analysis, of which, 1575 THA (3.1%) and 2490 TKA (3.5%) patients suffered postdischarge severe complications or unplanned readmissions. These patients were older, smokers, obese, and functionally dependent (P < .001 for all). In multivariate analysis, severe adverse event predischarge, age, male gender, functional status, and 10 other variables were all associated with ≥1.22 odds of postdischarge severe adverse event or readmission (P < .05). THA and TKA patients with 2, 3, or ≥4 risk factors had 1.43-5.06 times odds of complications within 14 days post discharge and 1.41-3.68 times odds of complications beyond 14 days compared to those with 0 risk factors (P < .001 for all).Conclusion
Risk factors can be used to predict which home-discharged TJA patients are at greatest risk of postdischarge complications. Given that this is a growing population, we recommend the development of formal risk-stratification protocols for home-discharged TJA patients. 相似文献9.

Background
Although it has been shown that anxiety and depression are associated with increased complications after total joint arthroplasty (TJA), the outcomes of TJA in patients with a history of psychosis are unknown. This study evaluated the influence of bipolar and schizophrenic disorders on complications after TJA, particularly aseptic and septic revisions.Methods
A retrospective review of 156 TJAs (125 primaries and 31 revisions) was performed at a single institution from 2000 to 2015. Bipolar and schizophrenic patients were identified based on International Classification of Diseases, Ninth Revision codes or by those actively taking anti-psychotic medications, followed by manual chart review to confirm diagnoses. The psychosis patient cohort was matched 3:1 for a variety of factors. Revisions and readmissions were evaluated. Survivorship curves were generated.Results
Patients with schizophrenia or bipolar disorder had an increased odds of developing peri-prosthetic joint infection at 90 days (odds ratio [OR] 3.34, P = .049), 2 years (OR 3.94, P = .004), and at any time point (OR 4.32, P = .002). Psychosis patients had increased odds of aseptic and mechanical revisions at all endpoints, particularly from dislocation. Psychosis patients had a higher number of post-operative emergency department visits (P < .001), and were more likely to be discharged to a rehabilitation facility (P < .001).Conclusions
Patients with bipolar affective disorder or schizophrenia may have multiple barriers to self-care after TJA, and are at an increased risk for undergoing revision TJA for prosthetic joint infection and mechanical causes. Increased pre-operative education and screening of this patient population may be necessary prior to performing TJA. 相似文献10.

Background
Interest in outpatient/same-day discharge (SDD) total hip arthroplasty (THA) has been increasing over the last several years. There is considerable debate in the literature regarding the complication and readmission rates of these patients. To evaluate and validate the safety and efficacy of our institutional SDD THA care pathway, we compared the outcomes of patients undergoing SDD THA with patients who had a similar comorbidity profile and underwent inpatient THA.Methods
A retrospective review was conducted on 164 patients who underwent SDD THA from January 2015 to September 2016. The Risk of Readmission Tool, a validated risk stratification instrument, was applied to all inpatient THAs performed from June 2014 to December 2016. A cutoff Risk of Readmission Tool score < 3 was used to produce a cohort of 1858 inpatient THA patients, all of whom had a similar risk profile to patients who underwent SDD THA. Medicare patients were excluded from the inpatient THA cohort, which left a final inpatient sample of 1315 patients.Each cohort was evaluated for demographic variables, length of stay, 30-/90-day readmissions, and discharge disposition.Results
The SDD THA cohort had significantly lower body mass index (26.9 vs 28.2 kg/m2; P = .002), had fewer minorities (89.6% vs 66.3% Caucasians; P < .001), was exclusively commercial insurance (100% vs 36.3%), had a shorter length of stay (0.37 vs 2.3 days, P < .001), and was exclusively discharged home (100% vs 92.6%). There was no statistically significant difference in 30-day readmission rates between either cohort (SDD 0.6% vs inpatient 1.6%; P = .325). However, the SDD cohort had a significantly lower rate of 90-day readmissions than the inpatient cohort (0.6% vs 3.6%; P = .014).Conclusion
The use of an institutional SDD THA care pathway can produce results with equivalent or better short-term outcomes than that of traditional inpatient THA. 相似文献11.

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12.

Background
Current patient selection criteria and medical risk stratification methods for outpatient primary total joint arthroplasty (TJA) surgery are unproven. This study assessed the predictive ability of a medically based risk assessment score in selecting patients for outpatient and short stay surgery.Methods
A retrospective review of 1120 consecutive primary TJAs in an early discharge program was performed. An Outpatient Arthroplasty Risk Assessment (“OARA”) score was developed by a high-volume arthroplasty surgeon and perioperative internal medicine specialist to stratify patients as “low-moderate risk (≤59)” and “not appropriate” (≥60) for early discharge. OARA, American Society of Anesthesiologists Physical Status Classification System (ASA-PS), and Charlson comorbidity index (CCI) scores were analyzed with respect to length of stay.Results
The positive predictive value of the OARA score was 81.6% for the same or the next day discharge, compared with that of 56.4% for ASA-PS (P < .001) and 70.3% for CCI (P = .002) scores. Patients with OARA scores ≤59 were 2.0 (95% confidence interval [CI], 1.4-2.8) times more likely to be discharged early than those with scores ≥60 (P < .001), while a low ASA-PS score was 1.7 (95% CI, 1.2-2.3) times more likely to be discharged early (P = .001). CCI did not predict early discharge (P ≥ .301). With deliberate patient education and expectations for outpatient discharge, the odds of early discharge predicted by the OARA score, but not the ASA-PS score, increased to 2.7 (95% CI, 1.7-4.2).Conclusion
The OARA score for primary TJA has more precise predictive ability than the ASA-PS and CCI scores for the same or next day discharge and is enhanced with a robust patient education program to establish appropriate expectations for early discharge. Early results suggest that the OARA score can successfully facilitate appropriate patient selection for outpatient TJA, although consideration of clinical program maturity before adoption of the score is advised. 相似文献13.

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14.

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15.

Background
The purpose of this study is to determine the incidence, risk factors, and clinical implications of pneumonia following total joint arthroplasty (TJA).Methods
The American College of Surgeons National Surgical Quality Improvement Program was used to conduct a retrospective cohort study of patients undergoing TJA. Independent risk factors for the development of pneumonia within 30 days of TJA were identified using multivariate regression. Mortality and readmission rates were compared between patients who did and did not develop pneumonia. Multivariate regression was used to adjust for all demographic, comorbidity, and procedural characteristics.Results
In total, 171,200 patients met inclusion criteria, of whom 66,493 (38.8%) underwent THA and 104,707 (61.2%) underwent TKA. Of the 171,200 patients, 590 developed pneumonia, yielding a rate of 0.34% (95% confidence interval = 0.32%-0.37%). Independent risk factors for pneumonia were chronic obstructive pulmonary disease, diabetes mellitus, greater age (most notably ≥80 years), dyspnea on exertion, dependent functional status, lower body mass index, hypertension, current smoker status, and male sex. The subset of patients who developed pneumonia following discharge had a higher readmission rate (82.1% vs 3.4%, adjusted relative risk [RR] = 16.6, P < .001) and a higher mortality rate (3.7% vs 0.1%, adjusted RR = 19.4, P < .001). Among 124 total mortalities, 22 (17.7%) occurred in patients who had developed pneumonia.Conclusion
Pneumonia is a serious complication following TJA that occurs in approximately 1 in 300 patients. Approximately 4 in 5 patients who develop pneumonia are subsequently readmitted, and approximately 1 in 25 die. Given the serious implications of this complication, evidence-based pneumonia prevention programs including oral hygiene with chlorhexidine, sitting upright for meals, elevation of the head of the bed to at least 30°, aggressive incentive spirometry, and early ambulation should be considered for patients at greatest risk. 相似文献16.

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17.

Background
Total joint arthroplasty (TJA) is a highly successful treatment, but is burdensome to the national healthcare budget. National quality initiatives seek to reduce costly complications. Smoking's role in perioperative complication after TJA is less well known. This study aims to identify smoking's independent contribution to the risk of short-term complication after TJA.Methods
All patients undergoing primary TJA between 2011 and 2012 were selected from the American College of Surgeon's National Surgical Quality Improvement Program's database. Outcomes of interest included rates of readmission, reoperation, mortality, surgical complications, and medical complications. To eliminate confounders between smokers and nonsmokers, a propensity score was used to generate a 1:1 match between groups.Results
A total of 1251 smokers undergoing TJA met inclusion criteria. Smokers in the combined total hip and knee arthroplasty cohort had higher 30-day readmission (4.8% vs 3.2%, P = .041), were more likely to have a surgical complication (odds ratio 1.84, 95% confidence interval 1.21-2.80), and had a higher rate of deep surgical site infection (SSI) (1.1% vs 0.2%, P = .007).Analysis of total hip arthroplasty only revealed that smokers had higher rates of deep SSI (1.3% vs 0.2%, P = .038) and higher readmission rate (4.3% vs 2.2%, P = .034). Analysis of total knee arthroplasty only revealed greater surgical complications (2.8% vs 1.2%, P = .048) and superficial SSI (1.8% vs 0.2%, P = .002) in smokers.Conclusion
Smoking in TJA is associated with higher rates of SSI, surgical complications, and readmission. 相似文献18.

Background
Mental illness is an often overlooked comorbidity in the total joint arthroplasty (TJA) population. The purpose of this study was to evaluate the risk of schizophrenia on the outcomes of TJA.Methods
The nationwide inpatient sample was used to identify a cohort of 505,840 patients having total hip arthroplasty between 2009 and 2012, of which 953 patients (0.2%) had been diagnosed with schizophrenia. Multivariate logistic regression was used to identify the impact of schizophrenia on short-term medical and surgical complications. Differences in length of stay and discharge disposition were also compared.Results
Schizophrenic patients are 15 times more likely to have pulmonary insufficiency after surgery (odds ratio [OR] 15.1, P = .0133). Patients were 11 times more likely to have mental status changes (OR 11.1, P = .0002), 3 times more likely to have a mechanical complication of the implant (OR 3.2, P = .0031), and 2 times more likely to require a transfusion (OR 2.4, P < .0001). All-cause medical (OR 2.2, P < .0001) and surgical (OR 1.5, P < .0001) complications were higher in schizophrenic patients. Patients stayed 0.63 days longer in the hospital (P < .0001), and were 3 times more likely to discharge to a facility (OR 2.7, P < .0001).Conclusions
TJA in patients with schizophrenia had markedly increased complications. Particularly, pulmonary complications, mechanical complications of the implant, mental status changes, and transfusion rates were higher. Future risk adjustment models should include schizophrenia as a major contributor to increased complications. 相似文献19.

Background
A subset of patients who undergo total knee arthroplasty (TKA) are on methadone maintenance. They require more and often unpredictable quantities of opioids to function as effective painkillers. This study aims to compare the opioid requirements and the immediate postoperative course for patients on methadone maintenance with those who are not, after a TKA.Methods
A retrospective, case-control study was performed. From 2005 to 2010, 36 patients, who underwent a unilateral TKA, on chronic methadone maintenance were identified. A control group matched for age, gender, and body mass index comprised patients from the same period, who did not self-report taking methadone. Chart review and analysis of patient demographics, type of anesthesia used, preoperative methadone use, inpatient opioid use (converted to oral morphine equivalent doses), need for in-house pain management consult, length of hospital stay, and need for reoperation were performed.Results
Patients on chronic methadone maintenance used significantly more opioids than patients not on methadone during their entire inpatient stay (P < .001). This was demonstrated by a higher median daily usage of opioids and higher patient-controlled analgesia usage. Patients on methadone maintenance had a significantly longer postoperative inpatient hospitalization (P < .001). Finally, these patients required significantly more inpatient pain management referrals (P = .025).Conclusion
There is a significantly higher opioid requirement, length of stay, and pain management consults in patients on methadone maintenance compared with those who are not after a TKA. These patients may benefit from a nonroutine approach to perioperative care in TKA. 相似文献20.
