BackgroundPatients with hip and knee arthritis often undergo bilateral total hip arthroplasty (THA) and total knee arthroplasty (TKA) in a staged or simultaneous fashion. However, when staged, the incidence and factors associated with having both procedures performed by the same surgeon or different surgeon are not well studied.MethodsAll patients undergoing nonsimultaneous bilateral THA or TKA for osteoarthritis were abstracted from the 2010 to 2020 PearlDiver Mariner administrative database. The National Provider Identifier number was used to determine whether the same surgeon performed both surgeries. Demographics, comorbidities, and 90-day complications after the first joint replacement were assessed as possible independent predictors of utilizing a different surgeon for the contralateral joint.ResultsOf 87,593 staged bilateral THAs, the same surgeon performed 40,707 (46.5%) arthroplasties. Of 147,938 staged bilateral TKAs, the same surgeon performed 77,072 (52.1%) arthroplasties. Notably, older cohorts of patients had independent, stepwise, and significantly greater odds of changing surgeons for the contralateral THA and TKA. Those patients who were insured by Medicare and Medicaid had significantly lower odds of changing surgeons. For both THA and TKA, surgical and implant-related adverse events (surgical site infection/periprosthetic joint infection, periprosthetic fracture, dislocation, manipulation) carried the greatest odds of undergoing the contralateral replacement with a different surgeon.ConclusionPatients covered by Medicaid and sicker patients were significancy less likely to switch surgeons for their contralateral THA or TKA. Additionally, patients experiencing a surgery-related adverse event within 90 days of their first THA or TKA had significantly, increased odds of switching surgeons for their subsequent TJA. 相似文献

Objective
To determine the clinical significance of tachycardia in the postoperative period.Patients and Methods
Individuals 18 years or older undergoing hip and knee arthroplasty were included in the study. Two data sets were collected from different time periods: development data set from January 1, 2011, through December 31, 2011, and validation data set from December 1, 2012, through September 1, 2014. We used the development data set to identify the optimal definition of tachycardia with the strongest association with the vascular composite outcome (pulmonary embolism and myocardial necrosis and infarction). The predictive value of this definition was assessed in the validation data set for each outcome of interest, pulmonary embolism, myocardial necrosis and infarction, and infection using multiple logistic regression to control for known risk factors.Results
In 1755 patients in the development data set, a maximum heart rate (HR) greater than 110 beats/min was found to be the best cutoff as a correlate of the composite vascular outcome. Of the 4621 patients who underwent arthroplasty in the validation data set, 40 (0.9%) had pulmonary embolism. The maximum HR greater than 110 beats/min had an odds ratio (OR) of 9.39 (95% CI, 4.67-18.87; sensitivity, 72.5%; specificity, 78.0%; positive predictive value, 2.8%; negative predictive value, 99.7%) for pulmonary embolism. Ninety-seven patients (2.1%) had myocardial necrosis (elevated troponin). The maximum HR greater than 110 beats/min had an OR of 4.71 (95% CI, 3.06-7.24; sensitivity, 47.4%; specificity, 78.1%; positive predictive value, 4.4%; negative predictive value, 98.6%) for this outcome. Thirteen (.3%) patients had myocardial infarction according to our predetermined definition, and the maximum HR greater than 110 beats/min had an OR of 1.72 (95% CI, 0.47-6.27).Conclusion
Postoperative tachycardia within the first 4 days of surgery should not be dismissed as a postoperative variation in HR, but may precede clinically significant adverse outcomes. 相似文献4.

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

BackgroundRacial and ethnic disparities within the field of total joint arthroplasty (TJA) have been extensively reported. To date, however, it remains unknown how these disparities have translated to the outpatient TJA (OP-TJA) setting. The purposes of this study were to compare relative OP-TJA utilization rates between White and Black patients from 2011-2019 and assess how these differences in utilization have evolved over time.MethodsWe conducted a retrospective review from 2011-2019 using the National Surgical Quality Improvement Program (NSQIP). Differences in the relative utilization of OP (same-day discharge) versus inpatient TJA between White and Black patients were assessed and trended over time. Multivariable logistic regressions were run to adjust for baseline patient factors and comorbidities.ResultsDuring the study period, Black patients were significantly less likely to undergo OP-TJA when compared to White patients (P < .001 for both outpatient total knee arthroplasty and outpatient total hip arthroplasty [OP-THA]). From 2011 to 2019, an emerging disparity was found in outpatient total knee arthroplasty and OP-THA utilization between White and Black patients (eg, White versus Black OP-THA: 0.4% versus 0.6% in 2011 compared with 10.2% versus 5.9% in 2019, Ptrend < .001). These results held in all adjusted analyses.ConclusionIn this study we found evidence of emerging and worsening racial disparities in the relative utilization of OP-TJA procedures between White and Black patients. These results highlight the need for early intervention by orthopaedic surgeons and policy makers alike to address these emerging inequalities in access to care before they become entrenched within our systems of orthopaedic care. 相似文献

BackgroundProvider-run “joint classes” educate total joint arthroplasty (TJA) patients on how to best prepare for surgery and maximize recovery. There is no research on potential healthcare inequities in the context of joint classes or on the impact of the recent shift toward telehealth due to coronavirus disease 2019 (COVID-19). Using data from a large metropolitan health system, we aimed to (1) identify demographic patterns in prepandemic joint class attendance and (2) understand the impact of telehealth on attendance.MethodsWe included data on 3,090 TJA patients from three centers, each with a separately operated joint class. Attendance patterns were assessed prepandemic and after the resumption of elective surgeries when classes transitioned to telehealth. Statistical testing included standardized differences (SD > 0.1 indicates significance) and a multivariate linear regression.ResultsThe in-person and telehealth attendance rates were 69.9% and 69.2%, respectively. Joint class attendance was significantly higher for non-White, Hispanic, non-English primary language, Medicaid, and Medicare patients (all SD > 0.1). Age was a determinant of attendance for telehealth (SD > 0.1) but not for in-person (SD = 0.04). Contrastingly, physical distance from hospital was significant for in-person (SD > 0.1) but not for telehealth (SD = 0.06). On a multivariate analysis, distance from hospital (P < .05) and telehealth (P < .0001) were predictors of failed class attendance.ConclusionThis work highlights the relative importance of joint classes in specific subgroups of patients. Although telehealth attendance was lower, telehealth alleviated barriers to access related to physical distance but increased barriers for older patients. These results can guide providers on preoperative education and the implementation of telehealth. 相似文献

BackgroundIn response to the coronavirus disease 2019 (COVID-19) pandemic, US hospitals have canceled elective surgeries. This decline in total joint arthroplasty (TJA) revenue may place financial strain on hospitals. Our goal was to quantify the impact of COVID-19 on the public interest in elective TJA.MethodsThe Google Search Volume Index (GSVI) identified the terms “knee replacement,” “hip replacement,” and “orthopedic surgeon” as the most common to describe TJA. The term “elective surgery cancellation” was also analyzed. Weekly GSVI data were extracted between 04-01-2015 and 04-04-2020. Time series analysis was conducted and state GSVI values were compared with COVID-19 prevalence and unemployment claims.ResultsThe relative public interest in elective TJA has sharply declined since the WHO declaration of COVID-19 as a global pandemic. Between 03-01-2020 and 03-29-2020, the popularity of searches for “knee replacement”, “hip replacement,” and “orthopedic surgeon” dropped by 62.1%, 52.1%, and 44.3%, respectively. A concurrent spike was observed for the term “elective surgery cancellation.” California, New Hampshire, Maine, and Nevada showed a low relative rate for TJA searches, and the highest increase in unemployment claims.ConclusionThe onset of COVID-19 correlates with declining relative popularity of searches related to elective TJA. Higher volume of COVID-19 cases in certain states may correspond with lower relative search popularity, although this correlation remains unclear. These results portend the possibility of a decline in elective TJA case volume, further straining hospitals. Further research is required to inform stakeholders how best to proceed and determine any sustained effects from the current diminished relative interest in TJA.Level of EvidenceLevel III. 相似文献

Background
The arthroplasty population increasingly presents with comorbid conditions linked to elevated risk of postsurgical complications. Current quality improvement initiatives require providers to more accurately assess and manage risk presurgically. In this investigation, we assess the effect of metabolic syndrome (MetS), as well as the effect of body mass index (BMI) within MetS, on the risk of complication following hip and knee arthroplasty.Methods
We queried the American College of Surgeons National Surgical Quality Improvement Program database for total hip or knee arthroplasty cases. Thirty-day rates of Centers for Medicare and Medicaid Services (CMS)-reportable complications, wound complications, and readmissions were compared between patients with and without a diagnosis of MetS using multivariate logistic regression. Arthroplasty cases with a diagnosis of MetS were further stratified according to World Health Organization BMI class, and the role of BMI within the context of MetS was assessed.Results
Of the 107,117 included patients, 11,030 (10.3%) had MetS. MetS was significantly associated with CMS complications (odds ratio [OR] = 1.415; 95% confidence interval [CI], 1.306-1.533; P < .001), wound complications (OR = 1.749; 95% CI, 1.482-2.064; P < .001), and readmission (OR = 1.451; 95% CI, 1.314-1.602; P < .001). When MetS was assessed by individual BMI class, the MetS + BMI >40 group was associated with significantly higher risk of CMS complications, wound complications, and readmission compared to the lower MetS BMI groups.Conclusion
MetS is an independent risk factor for CMS-reportable complications, wound complications, and readmission following total joint arthroplasty. The risk attributable to MetS exists irrespective of obesity class and increases as BMI increases. 相似文献10.
