BACKGROUND: Antimicrobial envelopes reduce the incidence of cardiac implantable electronic device infections, but their cost restricts routine use in the United Kingdom. Risk scoring could help to identify which patients would most benefit from this technology. METHODS: A novel risk score (BLISTER [Blood results, Long procedure time, Immunosuppressed, Sixty years old (or younger), Type of procedure, Early re-intervention, Repeat procedure]) was derived from multivariate analysis of factors associated with cardiac implantable electronic device infection. Diagnostic utility was assessed against the existing PADIT score (Prior procedure, Age, Depressed renal function, Immunocompromised, Type of procedure) in both standard and high-risk external validation cohorts, and cost-utility models examined different BLISTER and PADIT score thresholds for TYRX (Medtronic; Minneapolis, MN) antimicrobial envelope allocation. RESULTS: In a derivation cohort (n=7383), cardiac implantable electronic device infection occurred in 59 individuals within 12 months of a procedure (event rate, 0.8%). In addition to the PADIT score constituents, lead extraction (hazard ratio, 3.3 [95% CI, 1.9-6.1]; P<0.0001), C-reactive protein >50 mg/L (hazard ratio, 3.0 [95% CI, 1.4-6.4]; P=0.005), reintervention within 2 years (hazard ratio, 10.1 [95% CI, 5.6-17.9]; P<0.0001), and top-quartile procedure duration (hazard ratio, 2.6 [95% CI, 1.6-4.1]; P=0.001) were independent predictors of infection. The BLISTER score demonstrated superior discriminative performance versus PADIT in the standard risk (n=2854, event rate: 0.8%, area under the curve, 0.82 versus 0.71; P=0.001) and high-risk validation cohorts (n=1961, event rate: 2.0%, area under the curve, 0.77 versus 0.69; P=0.001), and in all patients (n=12â 198, event rate: 1%, area under the curve, 0.8 versus 0.75, P=0.002). In decision-analytic modeling, the optimum scenario assigned antimicrobial envelopes to patients with BLISTER scores ≥6 (10.8%), delivering a significant reduction in infections (relative risk reduction, 30%; P=0.036) within the National Institute for Health and Care Excellence cost-utility thresholds (incremental cost-effectiveness ratio, £18â 446). CONCLUSIONS: The BLISTER score (https://qxmd.com/calculate/calculator_876/the-blister-score-for-cied-infection) was a valid predictor of cardiac implantable electronic device infection, and could facilitate cost-effective antimicrobial envelope allocation to high-risk patients.

INTRODUCTION: The use of antibiotic-laden bone cement (ALBC) for infection prophylaxis in the setting of primary total knee arthroplasty (TKA) remains controversial. Using data from the American Joint Replacement Registry (AJRR), (1) we examined the demographics of ALBC usage in the United States and (2) identified the effect of prophylactic commercially available ALBC on early revision and readmission for prosthetic joint infection (PJI) after primary TKA. METHODS: This is a retrospective cohort study of the AJRR from 2017 to 2020. Patients older than 65 years undergoing primary cemented TKA with or without the use of commercially available antibiotic cement were eligible for inclusion (N = 251,506 patients). Data were linked to available Medicare claims to maximize revision outcomes. Demographics including age, sex, race/ethnicity, Charlson Comorbidity Index (CCI), preoperative inflammatory arthritis, region, and body mass index (BMI) class were recorded. Cox proportional hazards regression analysis was used to evaluate the association between the two outcome measures and ALBC usage. RESULTS: Patients undergoing cemented TKA with ALBC were more likely to be Non-Hispanic Black ( P < 0.001), have a CCI of 2 or 3 ( P < 0.001), reside in the South ( P < 0.001), and had a higher mean BMI ( P < 0.001). In the regression models, ALBC usage was associated with increased risk of 90-day revision for PJI (hazards ratio 2.175 [95% confidence interval] 1.698 to 2.787) ( P < 0.001) and was not associated with 90-day all-cause readmissions. Male sex, higher CCI, and BMI >35 were all independently associated with 90-day revision for PJI. DISCUSSION: The use of commercial ALBC in patients older than 65 years for primary TKA in the AJRR was not closely associated with underlying comorbidities suggesting that hospital-level and surgeon-level factors influence its use. In addition, ALBC use did not decrease the risk of 90-day revision for PJI and was not associated with 90-day readmission rates.

Prosthetic joint infection (PJI) is a costly and potentially fatal complication in total ankle arthroplasty (TAA). Some surgeons apply topical vancomycin powder to minimize the risk of infection during TAA procedures. The purpose of our study was to determine the cost-effectiveness of using vancomycin powder to prevent PJI following TAA and to propose an economic model that can be applied by foot and ankle surgeons in their decision to incorporate vancomycin powder in practice. Using our institution's records of the cost of 1 g of topical vancomycin powder, we performed a break-even analysis and calculated the absolute risk reduction and number needed to treat for varying costs of vancomycin powder, PJI infection rates, and costs of TAA revision. Costing $3.06 per gram at our institution, vancomycin powder was determined to be cost-effective in TAA if the PJI rate of 3% decreased by an absolute risk reduction of 0.02% (Number Needed to Treat = 5304). Furthermore, our results indicate that vancomycin powder can be highly cost-effective across a wide range of costs, PJI infection rates, and varying costs of TAA revision. The use of vancomycin powder remained cost-effective even when (1) the price of vancomycin powder was as low as $2.50 to as high as $100.00, (2) infection rates ranged from .05 to 3%, and (3) the cost of the TAA revision procedure ranged from $1000 to $10 000.Levels of Evidence: IV.

BACKGROUND: The use of tranexamic acid (TXA) has become widespread in orthopedics to promote hemostasis and has been successfully used to reduce blood loss and infection risk in joint arthroplasty. However, the cost effectiveness of routine TXA use for the prevention of periprosthetic infections in total shoulder arthroplasty remains unknown. METHODS: The acquisition cost of TXA ($5.22) for our institution, along with values from the literature for the average cost of infection-related care ($55,243) and the baseline infection rates for patients without TXA use (0.70%),were used to perform a break-even analysis. The absolute risk reduction (ARR) of infection necessary to justify the prophylactic use of TXA in shoulder arthroplasty was calculated from the nontreated and break-even infection rates. RESULTS: TXA is considered cost-effective if it prevents one infection out of 10,583 total shoulder arthroplasty's (ARR = 0.009%). It is economically justifiable with an ARR range of 0.001% at a cost of $0.50/g to 0.181% at $100/g. At varying costs of infection-related care ($10,000-$100,000) and varying baseline infection rates (0.50%-8.00%) and routine use of TXA remained cost-effective. CONCLUSION: The use of TXA is an economically viable practice for infection prevention following shoulder arthroplasty if it reduces the infection rate by 0.009%. Future, prospective studies should be conducted to observe whether TXA reduces the infection rate by more than 0.009%, showing cost effectiveness.

Recent investigations have shown that closed incisional negative pressure wound therapy (ciNPWT) decreases the rate of postoperative wound complications following revision total knee arthroplasty (TKA). In this study, we used a break-even analysis to determine whether ciNPWT is a cost-effective measure for reducing prosthetic joint infection (PJI) after revision TKA. The cost of ciNPWT, cost of treatment for PJI, and baseline infection rates following revision TKA were collected from institutional data and the literature. The absolute risk reduction (ARR) in infection rate necessary for cost-effectiveness was calculated using break-even analysis. Using our institutional cost of ciNPWT ($600), this intervention would be cost-effective if the initial infection rate of revision TKA (9.0%) has an ARR of 0.92%. The ARR needed for cost-effectiveness remained constant across a wide range of initial infection rates and declined as treatment costs increased. The use of ciNPWT for infection prevention following revision TKA is cost-effective at both high and low initial infection rates, across a broad range of treatment costs, and at inflated product expenses.

INTRODUCTION: Infections are complications of Cardiac Implantable Electronic Device (CIED) procedures, associated with high mortality (20-25% at 1 year), long hospitalizations (23-30 days), and high costs for health-care systems (often higher than 30.000 ). The incidence rates are around 1-4%. Prevention strategies appear to be the best approach for minimizing the occurrence of CIED infections, but in real-world, the recommendations for the best practices are not always followed. Among the recommended preventive measures, the antibacterial envelope has proven to be effective in reducing CIED-related infections. AREAS COVERED: Published studies investigate the role of antibacterial envelopes in infection prevention and the use of infection risk scores to select high-risk patients undergoing CIED implantation/replacement who can benefit from additional preventive measures. EXPERT OPINION: A proficient selection of the best candidates for the antibacterial envelope can be the basis for reducing the healthcare system's costs, in line with the principles of cost-effectiveness. Risk scores have been developed to select patients at high risk of CIED infections and their use appears simple and more complete than individual factors alone. Among them, the PADIT score seems to be effective in selecting patients eligible for antibacterial envelope insertion, with a good cost-effectiveness profile.

This study evaluated whether the preoperative use and timing of the use of hyaluronic acid (HA) and/or corticosteroid (CS) injections were associated with an increased risk of periprosthetic joint infections (PJIs) following primary total knee arthroplasty (TKA). We tested the hypothesis that preoperative injection of HA or CS within 3 months prior to primary TKA was associated with an increased risk of PJI by specifically evaluating the association between PJI risk and (1) injection type; (2) timing; (3) patient demographic factors; and (4) surgery-related factors, such as surgeon injection volume, knee arthroscopy (pre- and postoperative), and hospital length of stay. The 5% Medicare part B claims database was queried for patients who received CS and/or HA injections. Cox proportional hazards regressions evaluated the risk of PJIs after TKA, adjusting for patient and clinical factors, as well as propensity scores. The unadjusted incidence of PJI at 2-year post-TKA was 0.75% for the CS group, 0.89% for the HA group, 0.96% for both CS and HA group, and 0.75% for those who did not use HA or CS in the 12 months before TKA. For patients who used HA and/or CS within 3 months prior to TKA, the unadjusted incidence of PJI at 2-year post-TKA was 0.75% for the CS group, 1.07% for the HA group, and 1.00% for both CS and HA group, compared with 0.77% for those who did not use HA or CS. The number of injections performed per year was inconsistently associated with PJI risk. Overall, we found that intra-articular injections given within the 4-month period prior to TKA were not associated with elevated PJI risk (evaluated at 1, 3, 12, and 24 months after the index TKA) within the elderly Medicare patient population.

Despite many preventive measures, including prophylactic antibiotics, periprosthetic joint infection (PJI) remains a devastating complication following arthroplasty, leading to pain, suffering, morbidity and substantial economic burden. Humans have a powerful innate immune system that can effectively control infections, if alerted quickly. Unfortunately, pathogens use many mechanisms to dampen innate immune responses. The study hypothesis was that immunomodulators that can jumpstart and direct innate immune responses (particularly neutrophils) at the surgical site of implant placement would boost immune responses and reduce PJI, even in the absence of antibiotics. To test this hypothesis, N-formyl-methionyl-leucyl-phenylalanine (fMLP) (a potent chemoattractant for phagocytic leukocytes including neutrophils) was used in a mouse model of PJI with Staphylococcus aureus (S. aureus). Mice receiving intramedullary femoral implants were divided into three groups: i) implant alone; ii) implant + S. aureus; iii) implant + fMLP + S. aureus. fMLP treatment reduced S. aureus infection levels by ~ 2-Log orders at day 3. Moreover, fMLP therapy reduced infection-induced peri-implant periosteal reaction, focal cortical loss and areas of inflammatory infiltrate in mice distal femora at day 10. Finally, fMLP treatment reduced pain behaviour and increased weight-bearing at the implant leg in infected mice at day 10. Data indicated that fMLP therapy is a promising novel approach for reducing PJI, if administered locally at surgical sites. Future work will be toward further enhancement and optimisation of an fMLP-based therapeutic approach through combination with antibiotics and/or implant coating with fMLP.

BACKGROUND: Cardiac implantable electronic device(CIED)infections are associated with significant morbidity, mortality, and increased healthcare expenses. Apart from standard systemic antibiotic therapy, locally acting agents are under investigation as a potential approach for the prevention of this complication. AIMS: The study aimed to summarize our experience with a gentamycin-collagen sponge (GCS) in a multi-component prevention strategy of cardiac implantable electronic device infection. METHODS: We retrospectively analyzed medical records of 312 consecutive patients who underwent CIED-related surgery and had at least a 6-month follow-up. All the individuals had GCS applied during surgery. An incidence of CIEDs-related infection in our group was compared to the risk level calculated according to the commonly used scores. Analysis of cost-effectiveness was also performed. RESULTS: Incidence of CIED-related infection, defined as a primary endpoint, occurred relatively rarely (0.33%) as compared to the infection risk calculated according to commonly used scores Prevention of Arrythmia Device Infection Trial (PADIT) - 0.83%; CIED-AI - 0.90% or Mittal score - 1.00%; P<0.001 - for all). We did not record any complications related to GCS. We analyzed the cost-effectiveness of our GCS-based approach, which appeared to be financially beneficial (number needed to treat 149-200; difference of CIED infection treatment cost and GCSs price was 5093-26525 $). CONCLUSIONS: We conclude that: (1) the use of GCS to reduce CIEDs infections is feasible and safe; (2) our multicomponent prevention strategy involving the GCS application seems to significantly reduce the rate of CIED infection, and it is cost-effective.

The occurrence of cardiac implantable electronic devices (CIED) infections and related adverse outcomes have an important financial impact on the healthcare system, with hospitalization length of stay (2-3 weeks on average) being the largest cost driver, including the cost of device system extraction and device replacement accounting for more than half of total costs. In the recent literature, the economic profile of the TYRX™ absorbable antibacterial envelope was analysed taking into account both randomized and non-randomized trial data. Economic analysis found that the envelope is associated with cost-effectiveness ratios below USA and European benchmarks in selected patients at increased risk of infection. Therefore, the TYRX™ envelope, by effectively reducing CIED infections, provides value according to the criteria of affordability currently adopted by USA and European healthcare systems.

AIMS: Recent evidence suggests that an antibiotic impregnated envelope inserted at time of cardiac implantable electronic device (CIED) implantation may reduce risk of subsequent CIED infection compared with standard of care (SoC). The objective of the current work was to perform a cost-effectiveness analysis comparing an antibiotic impregnated envelope with SoC at time of CIED insertion. METHODS AND RESULTS: Decision analytic models were used to project healthcare costs and benefits of two strategies, an antibiotic impregnated envelope plus SoC (Env+SoC) vs. SoC alone, in a cohort of patients undergoing CIED implantation over a 1-year time horizon. Evidence from published literature informed the model inputs. Probabilistic and deterministic sensitivity analyses were performed. The primary outcome was the incremental cost per infection prevented, assessed from the Canadian healthcare system perspective. Envelope plus SoC was associated with fewer CIED infection (7 CIED infections/1000 patients) at higher total costs ($29 033 000/1000 patients) compared with SoC (11 CIED infections and $27 926 000/1000 patients). The incremental cost per infection prevented over 1 year was $274 416. Use of Env+SoC was cost saving only when baseline CIED infection risk was increased to 6% (vs. base case of 1.2%). CONCLUSIONS: A strategy of Env+SoC was not economically favourable compared with SoC alone, and the opportunity cost of widescale implementation should be considered. Future work is required to develop validated risk stratification tools to identify patients at greatest risk of CIED infection. The value proposition of Env+SoC improves when applying this intervention to patients at greatest infection risk.

BACKGROUND: Prosthetic joint infection (PJI) is a catastrophic complication after total joint arthroplasty that exacts a substantial economic burden on the health-care system. This study used break-even analysis to investigate whether the use of silver-impregnated occlusive dressings is a cost-effective measure for preventing PJI after primary total knee arthroplasty (TKA) and total hip arthroplasty (THA). METHODS: Baseline infection rates after TKA and THA, the cost of revision arthroplasty for PJI, and the cost of a silver-impregnated occlusive dressing were determined based on institutional data and the existing literature. A break-even analysis was then conducted to calculate the minimal absolute risk reduction needed for cost-effectiveness. RESULTS: The use of silver-impregnated occlusive dressings would be economically viable at an infection rate of 1.10%, treatment costs of $25,692 for TKA PJI, and $31,753 for THA PJI and our institutional dressing price of $38.05 if it reduces infection rates after TKA by 0.15% (the number needed to treat [NNT] = 676) and THA by 0.12% (NNT = 835). The absolute risk reduction needed to maintain cost-effectiveness did not change with varying initial infection rates and remained less than 0.40% (NNT = 263) for infection treatment costs as low as $10,000 and less than 0.80% (NNT = 129) for dressing prices as high as $200. CONCLUSION: The use of silver-impregnated occlusive dressings is a cost-effective measure for infection prophylaxis after TKA and THA.

BACKGROUND: The dramatic increase in the use of cardiovascular implantable electronic devices (CIED) was associated with an increased rate of CIED infection, which has a high management cost. AIM OF THE STUDY: To test the safety and efficacy of a single-session protocol, aiming to reuse the infected pocket side and the same device and leads in patients with CIED pocket infection. PATIENTS AND METHODS: We included patients with isolated pocket infection between January 2015 and November 2019. The Patient was prepared by taking a swab for culture and sensitivity before the procedure. The pocket was debrided and the capsule was removed, the pocket was rinsed with povidone-iodine and hydrogen peroxide mixture, then packed with gauze sponge soaked with povidone-iodine. The device was debrided using ultrasonic irrigation and sterilized using gas plasma. The device was reimplanted and the wound was closed in layers. RESULTS: During the period of the study, we had 12 patients with isolated pocket infection. Nine presented with erosion, two with impending erosion, and one with a chronic sinus. Patient's age was 61.5 ± 7.64 years. The infection was diagnosed 14.2 ± 8.22 weeks post device implantation. They were admitted for 7.6 ± 1.54 days postprocedure. The follow-up duration was 26.5 ± 15 (1.7-52) months. Only one patient (8%) had a recurrence of the infection after 50 days of the procedure. CONCLUSION: Our protocol was successful in treating 92% of device-related pocket infection without the need to replace the device or the pocket side.

BACKGROUND: In the WRAP-IT trial (Worldwide Randomized Antibiotic Envelope Infection Prevention), adjunctive use of an absorbable antibacterial envelope resulted in a 40% reduction of major cardiac implantable electronic device infection without increased risk of complication in 6983 patients undergoing cardiac implantable electronic device revision, replacement, upgrade, or initial cardiac resynchronization therapy defibrillator implant. There is limited information on the cost-effectiveness of this strategy. As a prespecified objective, we evaluated antibacterial envelope cost-effectiveness compared with standard-of-care infection prevention strategies in the US healthcare system. METHODS: A decision tree model was used to compare costs and outcomes of antibacterial envelope (TYRX) use adjunctive to standard-of-care infection prevention versus standard-of-care alone over a lifelong time horizon. The analysis was performed from an integrated payer-provider network perspective. Infection rates, antibacterial envelope effectiveness, infection treatment costs and patterns, infection-related mortality, and utility estimates were obtained from the WRAP-IT trial. Life expectancy and long-term costs associated with device replacement, follow-up, and healthcare utilization were sourced from the literature. Costs and quality-adjusted life years were discounted at 3%. An upper willingness-to-pay threshold of $150 000 per quality-adjusted life year was used to determine cost-effectiveness, in alignment with the American College of Cardiology/American Heart Association practice guidelines and as supported by the World Health Organization and contemporary literature. RESULTS: The base case incremental cost-effectiveness ratio of the antibacterial envelope compared with standard-of-care was $112 603/quality-adjusted life year. The incremental cost-effectiveness ratio remained lower than the willingness-to-pay threshold in 74% of iterations in the probabilistic sensitivity analysis and was most sensitive to the following model inputs: infection-related mortality, life expectancy, and infection cost. CONCLUSIONS: The absorbable antibacterial envelope was associated with a cost-effectiveness ratio below contemporary benchmarks in the WRAP-IT patient population, suggesting that the envelope provides value for the US healthcare system by reducing the incidence of cardiac implantable electronic device infection.

The implantation of penile protheses for the surgical treatment of erectile dysfunction has risen in popularity over the past several decades. Considerable advances have been made in surgical protocol and device design, specifically targeting infection prevention. Despite these efforts, device infection remains a critical problem, which causes significant physical and emotional burden to the patient. The aim of this review is to broaden the discussion of best practices by not only examining practices in urology, but additionally delving into the field of orthopedic surgery to identify techniques and approaches that may be applied to penile prothesis surgery.

BACKGROUND: Higher rates of prosthetic joint infections (PJIs) are related to patient risk factors and/or to special surgical procedures such as revision total knee arthroplasty (rTKA). Among the measures discussed to better protect those patients from the higher infection risks use of dual antibiotic-loaded bone cement has emerged as a further prophylactic option. METHODS: This retrospective study included 246 patients undergoing strictly aseptic revision knee arthroplasty at our institution in the time period 2015-2018. Based on the type of bone cement used for the cementation of the revision prosthesis, 2 groups were defined. In total, 143 patients received the low-dose single antibiotic-loaded bone cement (SALBC) PALACOS R+G and 103 patients received the high-dose dual antibiotic-loaded bone cement (DALBC) COPAL G+C. The number of PJI cases in each group over a follow-up time of minimum 1 year was compared and the extra costs for the DALBC use calculated against the economic savings per each avoided PJI case on basis of 3 different assumptions (treatment costs and amount of cement use). RESULTS: Use of DALBC in aseptic rTKA was associated with a significant reduction in PJI cases (relative risk = 57%, PJI rate in the SALBC group 4.1% vs 0% in the DALBC group, P = 0.035). The calculated total savings per patient was $1367. Depending on the economic assumptions the range of savings was between $1413 (less favorable calculation model) and $3661 (most favorable calculation model). CONCLUSION: The use of DALBC in rTKA has been found to be more effective in preventing PJI and proved cost-efficient in all our cost-calculation models.

OBJECTIVES: This study aims to assess the methods employed by Turkish orthopedic surgeons to prevent periprosthetic joint infection (PJI) in total joint arthroplasty (TJA). PATIENTS AND METHODS: The data obtained for this study, conducted between January 2019 and February 2019, were gathered by sending out an online survey to Turkish Society of Orthopedics and Traumatology members (n=2,267). A total of 354 orthopedic surgeons responded and completed survey. The survey had 23 questions which include the experience, academic position, hospital where the physician works, monthly arthroplasty numbers, and infection prevention methods employed before, during, and after surgery. RESULTS: The period for antibiotics prophylaxis showed variability, with about 63% of surgeons using prophylaxis longer than 24 hours. In terms of academic position, 52.4% of professors and 52.8% of associate professors used prophylaxis for the first 24 hours whereas this rate was 31.3% in operators (p=0.01). Of surgeons, 50.7% who perform more than 10 arthroplasties per month and 33.6% of surgeons who perform less than 11 arthroplasties per month used 24-hour antibiotic prophylaxis (p=0.006). Blood glucose level assessment prior to surgery was performed by the majority of surgeons (94%). A total of 118 orthopedic surgeons (33.3%) performed methicillin- resistant Staphylococcus aureus (MRSA) decolonization with 54.7% of associate professors, 59.5% of professors, and 24.7% of operators (p=0.001). Only 60 surgeons (16.9%) checked vitamin D levels. CONCLUSION: Our study results demonstrated that the majority of orthopedic surgeons in Turkey do not follow the antibiotic prophylaxis recommendations and they use antibiotic prophylaxis for longer periods. Professors and associate professors, and surgeons with higher monthly arthroplasty numbers than surgeons with lower monthly arthroplasty numbers follow the recommended periods more than their counterparts. Most surgeons assess blood glucose levels whereas a small number of surgeons perform MRSA decolonization and check vitamin D levels.

BACKGROUND: The air in the operating room is considered a risk factor for surgical site infection (SSI) due to airborne bacteria shed from the surgical staff or from patients themselves. AIM: To assess the influence of validated operating room (OR) ventilation data on the risk of revision surgery due to deep infection after primary total hip arthroplasty (THA) reported to the Norwegian Arthroplasty Register (NAR). METHODS: Forty orthopaedic units reporting THAs to the NAR during the period 2005-2015 were included. The true type of OR ventilation in all hospitals at the time of primary THA was confirmed in a previous study. Unidirectional airflow (UDF) systems were subdivided into: small, low-volume, unidirectional vertical flow (lvUDVF) systems; large, high-volume, unidirectional vertical flow (hvUDVF) systems; and unidirectional horizontal flow (UDHF) systems. These three ventilation groups were compared with conventional, turbulent, mixing ventilation (CV). The association between the end-point, time to revision due to infection, and OR ventilation was estimated by calculating relative risks (RRs) in a multivariate Cox regression model, with adjustments for several patient- and surgery-related covariates. FINDINGS: A total of 51,292 primary THAs were eligible for assessment. Of these, 575 had been revised due to infection. A similar risk of revision due to infection after THA performed was found in ORs with lvUDVF and UDHF compared to CV. THAs performed in ORs with hvUDVF had lower risk of revision due to infection compared to CV (RR = 0.8; 95% CI: 0.6-0.9; P = 0.01). CONCLUSION: THAs performed in ORs with hvUDVF systems had lower risk of revision due to infection compared to THAs performed in ORs with CV systems. The perception that all UDF systems are similar and possibly harmful seems erroneous.
