Background
Studies have suggested that forced-air warmers (FAWs) increase contamination of the surgical site. In response, FAWs with high efficiency particulate air filters (FAW-HEPA) were introduced. This study compared infection rates following primary total joint arthroplasty (TJA) using FAW and FAW-HEPA.Methods
Primary TJA patients at a single healthcare system were retrospectively reviewed. A total of 5405 THA (n = 2419) and TKA (n = 2986) consecutive cases in 2013 and 2015 were identified. Patients in 2013 (n = 2792) had procedures using FAW, while FAW-HEPA was used in 2015 (n = 2613). The primary outcome was overall infection rate within 90-days. Sub-categorization of infections as periprosthetic joint infection (PJI) or surgical site infection (SSI) was also conducted. PJI was defined as reoperation with arthrotomy or meeting Musculoskeletal Infection Society (MSIS) criteria. SSI was defined as wound complications requiring antibiotics or irrigation/debridement.Results
The FAW and FAW-HEPA groups had similar rates of overall infection (1.65% [n = 46] vs 1.61% [n = 42], P > .99), SSI (1.18% [n = 33] vs 0.84% [n = 22], P = .27), and PJI (0.47% [n = 13] vs 0.77% [n = 20], P = .22). Regression models did not show FAW to be an independent risk factor for increased overall infection (odds ratio [OR] 1.00, 95% confidence interval [CI] 0.65-1.57, P = .97), SSI (OR 1.47, 95% CI 0.83-2.58, P = .18), or PJI (OR 0.53, 95% CI 0.25-1.13, P = .09).Conclusion
FAW were not correlated with a higher risk of overall infection, SSI, or PJI during TJA when compared to FAW-HEPA devices. 相似文献2.

Background
Staphylococcus aureus colonization has been identified as a key modifiable risk factor in the reduction of surgical site infections (SSI) related to elective total joint arthroplasty (TJA). We investigated the incidence of SSIs and cost-effectiveness of a universal decolonization protocol without screening consisting of nasal mupirocin and chlorhexidine before elective TJA compared to a program in which all subjects were screened for S aureus and selectively treated if positive.Methods
We reviewed 4186 primary TJAs from March 2011 through July 2015. Patients were divided into 2 cohorts based on the decolonization regimen used. Before May 2013, 1981 TJA patients were treated under a “screen and treat” program while the subsequent 2205 patients were treated under the universal protocol. We excluded the 3 months around the transition to control for treatment bias. Outcomes of interest included SSI and total hospital costs.Results
With a universal decolonization protocol, there was a significant decrease in both the overall SSI rate (5 vs 15 cases; 0.2% vs 0.8%; P = .013) and SSIs caused by S aureus organisms (2 vs 10; 0.09% vs 0.5%; P = .01). A cost analysis accounting for the cost to administer the universal regimen demonstrated an actual savings of $717,205.59. TJA complicated by SSI costs 4.6× more to treat than that of an uncomplicated primary TJA.Conclusion
Our universal decolonization paradigm for elective TJA is effective in reducing the overall rate of SSIs and promoting economic gains for the health system related to the downstream savings accrued from limiting future reoperations and hospitalizations. 相似文献3.

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4.

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5.

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6.
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7.

Background
Institutional pathways in total joint arthroplasty (TJA) have been shown to reduce costs and improve patient care, but questions remain regarding their efficacy in certain populations. We sought to evaluate the comprehensive effect of a rapid recovery perioperative TJA protocol in the Veterans Health Administration (VA) setting.Methods
In a VA hospital, a rapid recovery protocol was implemented for all patients undergoing primary total hip or knee arthroplasty. A retrospective chart review was performed comparing pre-protocol (n = 174) and protocol (n = 78) cohorts. Measured outcomes included length of stay (LOS), discharge destination, unplanned readmissions, overall complications, and total cost of healthcare during admission and at 30 and 90 days postoperatively.Results
After implementation of the protocol, the average LOS decreased from 3.2 to 1.7 days (P < .0001). In the protocol group, there was a 12.3% increase in patients discharging directly home (85.1% vs 97.4%, P = .005). There were lower unplanned readmissions (6.3% vs 3.8%, P = .56) and overall complications (7.5% vs 3.8%, P = .40), but these were not statistically significant. The summative cost of all perioperative healthcare was lower after implementation of the protocol during the inpatient stay ($19,015 vs $21,719, P = .002) and out to 30 days postoperatively ($21,083 vs $23,420, P = .03) and 90 days postoperatively ($24,189 vs $26,514, P = .07).Conclusion
In the VA setting, implementation of a rapid recovery TJA protocol led to decreased LOS, decreased cost of perioperative healthcare, and an increase in patients discharging directly home without increased readmission or complication rates. Such protocols are essential as we transition into an era of value-based arthroplasty. 相似文献8.

Background
Intrathecal morphine (ITM) combined with bupivacaine spinal anesthesia can improve postoperative pain, but has potential side effects of postoperative nausea/vomiting (PONV) and pruritus. With the use of multimodal analgesia and regional anesthetic techniques, postoperative pain control has improved significantly to a point where ITM may be avoided in total joint arthroplasty (TJA).Methods
We performed a retrospective study of primary TJA patients who underwent a standardized multimodal recovery pathway and received bupivacaine neuraxial anesthesia with ITM vs bupivacaine neuraxial anesthesia alone (control).Results
In total, 598 patients were identified (131 controls, 467 ITMs) with similar demographics. On postoperative day 0 (POD 0), ITM patients had significantly lower mean visual analog scale scores (1.5 ± 1.6 vs 2.5 ± 1.9, P < .001) and consumed less oral morphine equivalents (10.5 ± 25.4 vs 16.8 ± 27.2, P = .013). ITM patients walked further compared to controls by POD 1 (133.6 ± 159.6 vs 97.3 ± 141 m, P = .028) and were less likely to develop PONV during their entire hospital stay (38.5% vs 48.6%, P = .043). No significant differences were seen for total morphine equivalents consumption, rate of discharge to care facility, length of stay, and 90-day readmission rates.Conclusion
ITM was associated with improved POD 0 pain scores and less initial oral/intravenous opioid consumption, which likely contributes to the subsequent improved mobilization and lower rates of PONV. In the setting of a modern regional anesthesia and multimodal analgesia recovery plan for TJA, ITM can still be considered for its benefits. 相似文献9.

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10.

Background
The association between inadequate glycemic control and surgical site infection (SSI) following total joint arthroplasty (TJA) remains unclear. The aim of this study is to assess the relationship between perioperative glycemic control and the risk for SSI, mainly periprosthetic joint infection.Methods
We searched OVID-MEDLINE, Embase, and Web of Science from inception up to June 2017. The main independent variable was glycemic control as defined by glycated hemoglobin (HbA1C) or perioperative glucose values. The main outcome was SSI. Publication year, location, study design, sample population (size, age, gender), procedure, glycemic control assessment, infection outcome, results, confounders, and limitations were assessed. Studies included in the meta-analysis had stratified glycemic control using a distinct HbA1C cut-off.Results
Seventeen studies were included in this study. Meta-analysis of 10 studies suggested that elevated HbA1C levels were associated with a higher risk of SSI after TJA (pooled odds ratio 1.49, 95% confidence interval 0.94-2.37, P = .09) with significant heterogeneity between studies (I2 = 81.32%, P < .0001). In a subgroup analysis of studies considering HbA1C with a cut-off of 7% as uncontrolled, this association was no longer noticed (P = .50). All 5 studies that specifically assessed for SSI and perioperative hyperglycemia showed a significant association, which was usually attenuated after adjusting for covariates.Conclusion
Inadequate glycemic control was associated with increased risk for SSI after TJA. However, the optimal HbA1C threshold remains contentious. Pooled data does not support the conventional 7% cut-off for risk stratification. Future studies should examine new markers for determining adequate glycemic control. 相似文献11.

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12.

Background
Controversy remains regarding the outcomes after total joint arthroplasty (TJA) among patients with or without liver transplantation (LT). This study aimed at investigating the prevalence of TJA in patients after LT and comparing the morbidity and mortality with the non-LT group.Methods
We conducted a nationwide, population-based study, with data extracted from a universal health insurance database, based on the International Classification of Disease, Ninth Revision, Clinical Modification. Patients who underwent TJAs between January 2001 and December 2014 were included. Patients who had bilateral TJAs or a TJA before LT were excluded. A total of 43 patients with LT and 350,337 patients without LT were included. The analysis was implemented using data from all patients and those matched by 1-to-10 propensity score matching. Multivariable logistic regression was used to control confounding variables.Results
The prevalence of patients undergoing TJA after LT was 1.3% (43/3276). After propensity score matching, patients with LT were not associated with 30-day complications (adjusted odds ratio [aOR], 0.98; 95% confidence interval [CI], 0.93-1.03; P = .35), 30-day readmission rates (aOR, 0.93; 95% CI, 0.92-1.08; P = .87), 90-day complication rates (aOR, 0.95; 95% CI, 0.88-1.02; P = .16), 1-year infection rates (aOR, 1.04; 95% CI, 0.96-1.12; P = .35), reoperation rates (aOR, 1.06; 95% CI, 0.92-1.23; P = .41), or mortality (aOR, 0.91; 95% CI, 0.80-1.04; P = .18).Conclusion
The morbidity and mortality seem to be comparable whether TJA is performed in patients with or without LT. Methods for risk assessment would be feasible in liver transplant recipients. 相似文献13.

Background
Compared to total knee arthroplasty (TKA) for primary osteoarthritis, conversion TKAs in the post-traumatic setting are associated with increased operative times, infection rates, and readmissions. We aim at determining how post-traumatic osteoarthritis and previous knee surgery influence postoperative outcomes in conversion TKA.Methods
Seventy-two conversion TKA procedures with prior knee trauma at a single institution between April 2012 and 2016 were examined. Twenty-seven (37.5%) cases had a preoperative site-specific diagnosis such as fracture of the proximal tibia, distal femur, or patella whereas 45 (62.5%) cases had a preoperative diagnosis of significant soft-tissue trauma. These 2 groups were compared in terms of total implant cost, length of stay, complications, and readmission and reoperation rates. A subanalysis was conducted to evaluate the effects of previous knee surgery on surgical outcomes.Results
The postfracture TKA cohort suffered significantly higher early surgical site complications (22% vs 4.4%, P = .02) and 90-day readmissions (14.8% vs 2.2%, P = .042) compared to the soft-tissue trauma cohort. Operative time, total implant costs, length of stay, medical complications, 30-day readmissions, and 90-day reoperation rates did not significantly differ. It was also found that patients with multiple prior knee surgeries compared to one prior knee surgery are younger (53.0 vs 63.1, P = .003), healthier, and receive significantly more expensive implants (1.72 vs 1.07, P = .026). In addition, patients with previous open reduction internal fixations experience more surgical site complications than patients with previous arthroscopies (31% vs 3.3%, P = .042).Conclusion
Patients with previous site-specific fracture are more likely to experience surgical site complications and 90-day readmissions after conversion TKA than patients with previous soft-tissue knee trauma. Multiple previous knee surgeries appear to serve as an independent factor in the selection of costlier implants irrespective of preoperative diagnosis. 相似文献14.

Background
Increased operative time has been associated with increased complications after total joint arthroplasty (TJA). The purpose of the present study was to investigate the effect of operative time on short-term complications after TJA while also identifying patient and operative factors associated with prolonged operative times.Methods
The American College of Surgeons National Surgical Quality Improvement Program database was queried from 2011-2013 to identify all patients who underwent primary total hip or knee arthroplasty. Patients were stratified by operative time, and 30-day morbidity and mortality data compared using univariate and multivariable analyses.Results
We identified 99,444 patients who underwent primary TJA. The overall incidence of complications after TJA was 4.9%. Overall complications were increased in patients with operative times >120 minutes (5.9%) as compared to patients with operative times <60 minutes or 60-120 minutes (4.6% and 4.8%, respectively; P < .001). Wound complications, including surgical site infection, were also increased for procedures lasting >120 minutes. In a multivariable analysis, operative time exceeding 120 minutes remained an independent predictor of any complication and wound complication, with each 30-minute increase in operative time beyond 120 minutes further increasing risk. Patient age ≤65 years, male sex, black race, body mass index ≥30 kg/m2, and an American Society of Anesthesiologists classification of 3 or 4, predicted operative times >120 minutes.Conclusion
We found that operative time >120 minutes was associated with increased short-term morbidity and mortality after primary TJA. Younger age, male sex, black race, obesity, and increased comorbidity were risk factors for operative time exceeding 120 minutes. 相似文献15.

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16.

Background
Total hip arthroplasty (THA) and total knee arthroplasty (TKA) are common procedures with a risk of complications. Attempting to minimize complications, our institution implemented preoperative screening criteria for patients undergoing elective total joint replacement. Our study aimed to determine if screening criteria lowered total complications and/or surgical site infections (SSI).Methods
Two groups of consecutive patients undergoing TKA and THA at a single Veterans Affairs facility were evaluated prior to and after implementation of screening criteria, 520 and 475 respectively. Screening criteria included hemoglobin A1c ≤7, hemoglobin ≥11, body mass index ≤35, and albumin ≥3.5. Groups were analyzed for demographics, preoperative comorbidities, and postoperative complications. Rates of total complications and SSI were compared. Average follow-up was at least 2 years with minimum of 1 year.Results
Demographics and comorbidities outside the screening criteria were similar. Total complication rate was reduced from 35.4% to 14.8% (P < .01) after implementation of screening criteria. For TKA, total complications were reduced from 33.1% to 15.0% (P < .01) and for THA they were reduced from 42.4% to 14.2% (P < .01). SSI rates for combined TKA and THA were reduced from 4.4% to 1.3% (P < .01). For knees, SSI was reduced from 4.6% to 1.3% (P = .01) and was statistically significant. For THA, SSI decreased from 3.8% to 1.2% (P < .05).Conclusion
Our institution saw a statistically significant decrease in both SSI and total complications following implementation of preoperative screening criteria for elective TKA and THA. 相似文献17.

The use of perioperative dexamethasone has been proven to reduce pain and shorten recovery for patients undergoing total hip and knee arthroplasty. However, the effect of these medications on 90-day readmissions and the rates of clinically significant venous thromboembolic events (VTE) after total joint arthroplasty (TJA) remains unknown.Methods
Patients undergoing unilateral, primary total joint arthroplasty between 2009 and 2016 in a single institution were identified. There were 6617 patients who did not receive dexamethasone intraoperatively compared to 1293 patients who received a single, intraoperative, intravenous dose of dexamethasone (8-10 mg). The primary outcomes were the rate of clinically significant VTE and 90-day readmission. Secondary outcomes included wound complications, periprosthetic joint infection, and 90-day mortality.Results
While the overall rate of clinically symptomatic VTE was lower in the dexamethasone group, this did not reach significance in a univariate analysis (0.1% vs 0.2%, P = .353). Only body mass index (odds ratio [OR], 1.13; 95% confidence interval [CI], 1.03-1.24; P = .006) and longer length of stay (OR, 1.16; 95% CI, 1.06-1.28; P = .001) were associated with VTE in the multivariate analysis (OR, 0.31; 95% CI, 0.04-2.36; P = .319). However, the use of intravenous dexamethasone was independently associated with a reduction in 90-day readmission rate (1.6% vs 2.5%; OR, 0.57; 95% CI, 0.36-0.90; P = .016). There was no difference in the rate of periprosthetic joint infection or mortality.Conclusion
A single, intraoperative, low dose of dexamethasone is not associated with a reduction in clinically significant VTE but may be a safe and effective adjunct medication to lower 90-day readmission rates.Level of Evidence

Background
Unplanned hospital returns after total joint arthroplasty (TJA) reduce any cost savings in a bundled reimbursement model. We examine the incidence, risk factors, and costs for unplanned emergency department (ED) visits and readmissions within 30 days of index TJA.Methods
We retrospectively reviewed a consecutive series of 655 TJAs (382 total knee arthroplasty and 273 total hip arthroplasty) performed between April 2014 and March 2015. Preoperative diagnosis was osteoarthritis of the hip or knee (97%) or avascular necrosis of the hip (3%). Hospital costs were recorded for each ED visit and readmission episode.Results
Of the 655 TJAs reviewed, 55 (8.4%) returned to the hospital. Of these hospital returns, 35 patients (5.3%) returned for a total of 36 unplanned ED visits whereas the remaining 20 patients (3.1%) presented 22 readmissions within 30 days of index TJA. The 2 most common reasons for unplanned ED visits were postoperative pain/swelling (36%) and medication-related side effects (22%). Avascular necrosis of the hip was a significant risk factor for an unplanned ED visit (7.27 odds ratio [OR], 95% confidence interval [CI] 1.67-31.61, P = .008). Multiple logistic regression analysis revealed the following risk factors for readmission: body mass index (1.10 OR, 95% CI 1.02-1.78, P = .013), comorbidity >2 (2.07 OR, 95% CI 1.06-6.95, P = .037), and prior total knee arthroplasty (2.61 OR, 95% CI 1.01-6.72, P = .047). Ambulating on the day of surgery trended toward a lower risk for readmission (0.13 OR, 95% CI 0.02-1.10, P = .061). The 2 most common reasons for readmission were ileus (23%) and cellulitis (18%). The total cost associated with unplanned ED visits were $15,427 whereas costs of readmissions totaled $142,654.Conclusion
Unplanned ED visits and readmissions in the forthcoming bundled payments reimbursement model will reduce cost savings from rapid recovery protocols for TJA. Identifying and mitigating preventable causes of unplanned visits and readmissions will be critical to improving care and controlling costs. 相似文献19.

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20.
