Abstract
PURPOSE Preoperative anemia increases postoperative morbidity, mortality, and the risk of allogeneic transfusion. However, the incidence of preoperative anemia in patients undergoing total hip arthroplasty and total knee arthroplasty (TKA) and its relationship to postoperative outcomes has not been previously reported. METHODS We conducted a comprehensive literature search through PubMed, Cochrane Library, Web of Sincien, and Embase from inception to July 2023 to investigate the prevalence of preoperative anemia in patients undergoing Total Joint Arthroplasty, comorbidities between anemic and non-anemicpatients before surgery, and postoperative outcomes. postoperative outcomes were analyzed. Overall prevalence was calculated using a random-effects model, and heterogeneity between studies was examined by Cochran's Q test and quantified by the I2 statistic. Subgroup analyses and meta-regression analyses were performed to identify sources of heterogeneity. Publication bias was assessed by funnel plots and validated by Egger's test. RESULTS A total of 21 studies with 369,101 samples were included, all of which were retrospective cohort studies. 3 studies were of high quality and 18 studies were of moderate quality. The results showed that the prevalence of preoperative anemia was 22% in patients awaiting arthroplasty; subgroup analyses revealed that the prevalence of preoperative anemia was highest in patients awaiting revision of total knee arthroplasty; the highest prevalence of preoperative anemia was found in the Americas; preoperative anemia was more prevalent in the female than in the male population; and preoperative anemia with a history of preoperative anemia was more common in the female than in the male population. patients with a history of preoperative anemia; patients with joint replacement who had a history of preoperative anemia had an increased risk of infection, postoperative blood transfusion rate, postoperative blood transfusion, Deep vein thrombosis of the lower limbs, days in hospital, readmission within three months, and mortality compared with patients who did not have preoperative anemia. CONCLUSION The prevalence of preoperative anemia in patients awaiting total joint arthroplasty is 22%, and is higher in TKA and female patients undergoing revision, while preoperative anemia is detrimental to the patient's postoperative recovery and will increase the risk of postoperative complications, transfusion rates, days in the hospital, readmission rates, and mortality.

Allogeneic Blood Transfusion and Risk of Postoperative Complications in Patients with Mild and Moderate Anemia of Any Cause? A Retrospective Cohort Study in Total Revision Hip Surgery. Transfus Med Hemother 2024; 51:12-21. [PMID: 38314244 PMCID: PMC10836862 DOI: 10.1159/000530135] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2022] [Accepted: 02/26/2023] [Indexed: 02/06/2024] Open
Abstract
Introduction Patients undergoing revision total hip surgery (RTHS) have a high prevalence of mild and moderate preoperative anemia, associated with adverse outcomes. The aim of this study was to investigate the association of perioperative allogeneic blood transfusions (ABT) and postoperative complications in preoperatively mild compared to moderate anemic patients undergoing RTHS who did not receive a diagnostic anemia workup and treatment before surgery. Methods We included 1,765 patients between 2007 and 2019 at a university hospital. Patients were categorized according to their severity of anemia using the WHO criteria of mild, moderate, and severe anemia in the first Hb level of the case. Patients were grouped as having received no ABT, 1-2 units of ABT, or more than 2 units of ABT. Need for intraoperative ABT was assessed in accordance with institutional standards. Primary endpoint was the compound incidence of postoperative complications. Secondary outcomes included major/minor complications and length of hospital and ICU stay. Results Of the 1,765 patients, 31.0% were anemic of any cause before surgery. Transfusion rates were 81% in anemic patients and 41.2% in nonanemic patients. The adjusted risks for compound postoperative complication were significantly higher in patients with moderate anemia (OR 4.88, 95% CI: 1.54-13.15, p = 0.003) but not for patients with mild anemia (OR 1.93, 95% CI: 0.85-3.94, p < 0.090). Perioperative ABT was associated with significantly higher risks for complications in nonanemic patients and showed an increased risk for complications in all anemic patients. In RTHS, perioperative ABT as a treatment for moderate preoperative anemia of any cause was associated with a negative compound effect on postoperative complications, compared to anemia or ABT alone. Discussion ABT is associated with adverse outcomes of patients with moderate preoperative anemia before RTHS. For this reason, medical treatment of moderate preoperative anemia may be considered.

Pharmacological interventions for the prevention of bleeding in people undergoing elective hip or knee surgery: a systematic review and network meta-analysis. Cochrane Database Syst Rev 2024; 1:CD013295. [PMID: 38226724 PMCID: PMC10790339 DOI: 10.1002/14651858.cd013295.pub2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 01/17/2024]
Abstract
BACKGROUND Hip and knee replacement surgery is a well-established means of improving quality of life, but is associated with a significant risk of bleeding. One-third of people are estimated to be anaemic before hip or knee replacement surgery; coupled with the blood lost during surgery, up to 90% of individuals are anaemic postoperatively. As a result, people undergoing orthopaedic surgery receive 3.9% of all packed red blood cell transfusions in the UK. Bleeding and the need for allogeneic blood transfusions has been shown to increase the risk of surgical site infection and mortality, and is associated with an increased duration of hospital stay and costs associated with surgery. Reducing blood loss during surgery may reduce the risk of allogeneic blood transfusion, reduce costs and improve outcomes following surgery. Several pharmacological interventions are available and currently employed as part of routine clinical care. OBJECTIVES To determine the relative efficacy of pharmacological interventions for preventing blood loss in elective primary or revision hip or knee replacement, and to identify optimal administration of interventions regarding timing, dose and route, using network meta-analysis (NMA) methodology. SEARCH METHODS We searched the following databases for randomised controlled trials (RCTs) and systematic reviews, from inception to 18 October 2022: CENTRAL (the Cochrane Library), MEDLINE (Ovid), Embase (Ovid), CINAHL (EBSCOhost), Transfusion Evidence Library (Evidentia), ClinicalTrials.gov and WHO International Clinical Trials Registry Platform (ICTRP). SELECTION CRITERIA We included RCTs of people undergoing elective hip or knee surgery only. We excluded non-elective or emergency procedures, and studies published since 2010 that had not been prospectively registered (Cochrane Injuries policy). There were no restrictions on gender, ethnicity or age (adults only). We excluded studies that used standard of care as the comparator. Eligible interventions included: antifibrinolytics (tranexamic acid (TXA), aprotinin, epsilon-aminocaproic acid (EACA)), desmopressin, factor VIIa and XIII, fibrinogen, fibrin sealants and non-fibrin sealants. DATA COLLECTION AND ANALYSIS We performed the review according to standard Cochrane methodology. Two authors independently assessed trial eligibility and risk of bias, and extracted data. We assessed the certainty of the evidence using CINeMA. We presented direct (pairwise) results using RevMan Web and performed the NMA using BUGSnet. We were interested in the following primary outcomes: need for allogenic blood transfusion (up to 30 days) and all-cause mortality (deaths occurring up to 30 days after the operation), and the following secondary outcomes: mean number of transfusion episodes per person (up to 30 days), re-operation due to bleeding (within seven days), length of hospital stay and adverse events related to the intervention received. MAIN RESULTS We included a total of 102 studies. Twelve studies did not report the number of included participants; the other 90 studies included 8418 participants. Trials included more women (64%) than men (36%). In the NMA for allogeneic blood transfusion, we included 47 studies (4398 participants). Most studies examined TXA (58 arms, 56%). We found that TXA, given intra-articularly and orally at a total dose of greater than 3 g pre-incision, intraoperatively and postoperatively, ranked the highest, with an anticipated absolute effect of 147 fewer blood transfusions per 1000 people (150 fewer to 104 fewer) (53% chance of ranking 1st) within the NMA (risk ratio (RR) 0.02, 95% credible interval (CrI) 0 to 0.31; moderate-certainty evidence). This was followed by TXA given orally at a total dose of 3 g pre-incision and postoperatively (RR 0.06, 95% CrI 0.00 to 1.34; low-certainty evidence) and TXA given intravenously and orally at a total dose of greater than 3 g intraoperatively and postoperatively (RR 0.10, 95% CrI 0.02 to 0.55; low-certainty evidence). Aprotinin (RR 0.59, 95% CrI 0.36 to 0.96; low-certainty evidence), topical fibrin (RR 0.86, CrI 0.25 to 2.93; very low-certainty evidence) and EACA (RR 0.60, 95% CrI 0.29 to 1.27; very low-certainty evidence) were not shown to be as effective compared with TXA at reducing the risk of blood transfusion. We were unable to perform an NMA for our primary outcome all-cause mortality within 30 days of surgery due to the large number of studies with zero events, or because the outcome was not reported. In the NMA for deep vein thrombosis (DVT), we included 19 studies (2395 participants). Most studies examined TXA (27 arms, 64%). No studies assessed desmopressin, EACA or topical fibrin. We found that TXA given intravenously and orally at a total dose of greater than 3 g intraoperatively and postoperatively ranked the highest, with an anticipated absolute effect of 67 fewer DVTs per 1000 people (67 fewer to 34 more) (26% chance of ranking first) within the NMA (RR 0.16, 95% CrI 0.02 to 1.43; low-certainty evidence). This was followed by TXA given intravenously and intra-articularly at a total dose of 2 g pre-incision and intraoperatively (RR 0.21, 95% CrI 0.00 to 9.12; low-certainty evidence) and TXA given intravenously and intra-articularly, total dose greater than 3 g pre-incision, intraoperatively and postoperatively (RR 0.13, 95% CrI 0.01 to 3.11; low-certainty evidence). Aprotinin was not shown to be as effective compared with TXA (RR 0.67, 95% CrI 0.28 to 1.62; very low-certainty evidence). We were unable to perform an NMA for our secondary outcomes pulmonary embolism, myocardial infarction and CVA (stroke) within 30 days, mean number of transfusion episodes per person (up to 30 days), re-operation due to bleeding (within seven days), or length of hospital stay, due to the large number of studies with zero events, or because the outcome was not reported by enough studies to build a network. There are 30 ongoing trials planning to recruit 3776 participants, the majority examining TXA (26 trials). AUTHORS' CONCLUSIONS We found that of all the interventions studied, TXA is probably the most effective intervention for preventing bleeding in people undergoing hip or knee replacement surgery. Aprotinin and EACA may not be as effective as TXA at preventing the need for allogeneic blood transfusion. We were not able to draw strong conclusions on the optimal dose, route and timing of administration of TXA. We found that TXA given at higher doses tended to rank higher in the treatment hierarchy, and we also found that it may be more beneficial to use a mixed route of administration (oral and intra-articular, oral and intravenous, or intravenous and intra-articular). Oral administration may be as effective as intravenous administration of TXA. We found little to no evidence of harm associated with higher doses of tranexamic acid in the risk of DVT. However, we are not able to definitively draw these conclusions based on the trials included within this review.

Abstract
This study aimed to investigate the efficacy of tranexamic acid supplemented with local infiltration analgesia in reducing blood loss in patients undergoing unicompartmental knee arthroplasty (UKA). This retrospective study was conducted on 176 individuals with a mean age of 64.27 (standard deviation [SD], 7.16) years undergoing unicompartmental cemented knee arthroplasty. The patients were divided into three groups according to patient blood management: I, patients without additional bleeding protocol (control group); II, patients intravenously administered tranexamic acid (TXA) (TXA group); and III, patients with exact TXA protocol combined with intraoperative local infiltration analgesia (LIA) (TXA + LIA group). Blood loss was measured as a substitute for blood loss by the maximal haemoglobin (Hb) drop compared with the preoperative Hb level. The mean Hb drops for the control, TXA, and TXA + LIA groups were 2.24 (16.0%), 2.14 (15.4%), and 1.81 (12.6%) g/dl, respectively. The mean hospitalisation days for patients in the control, TXA, and TXA + LIA groups were 5.91 (SD 1.24), 5.16 (SD 0.95), and 4.51 (SD 0.71) days, respectively. The combination of TXA with LIA reduces perioperative blood loss for patients after UKA.

Abstract
BACKGROUND Anemia is highly prevalent in patients before hip joint revision surgery (HJRS) and is associated with an increased complication rate. This paper is the first to investigate costs, real diagnosis-related group (DRG) revenues and case coverage of preoperative anemia in elective HJRS. METHODS Medical data, transfusions, costs, and revenues of all patients undergoing HJRS at two campuses of the Charité -Universitätsmedizin Berlin between 2010 and 2017 were used for subgroup analyses and linear regressions. RESULTS Of 1187 patients included 354 (29.8%) showed preoperative anemia. A total of 565 (47.6%) patients were transfused with a clear predominance of anemic patients (72.6% vs. 37.0%, p < 0.001). Costs (12,318€ [9027;20,044€] vs. 8948€ [7501;11,339€], p < 0.001) and revenues (11,788€ [8992;16,298€] vs. 9611€ [8332;10,719€], p < 0.001) were higher for preoperatively anemic patients and the coverage was deficient (-1170€ [-4467;1238€] vs. 591€ [-1441;2103€], p < 0.001). In anemic patients, case contribution margins decreased with increasing transfusion rates (p ≤ 0.001). Comorbidities had no significant economic impact. CONCLUSION Preoperative anemia and perioperative transfusions in HJRS are associated with increased treatment costs and a financial undercoverage for healthcare providers and health insurance companies. Concepts for the treatment of preoperative anemia (e.g. patient blood management) could reduce treatment costs in the medium term.

Abstract
Background: Total joint arthroplasty (TJA) is one of the most common procedures performed in the United States. Outcomes of this elective procedure may be improved via preoperative optimization of modifiable risk factors. Purposes: We sought to summarize the literature on the clinical implications of preoperative risk factors in TJA and to develop recommendations regarding preoperative optimization of these risk factors. Methods: We searched PubMed in August 2019 with an update in September 2020 for English-language, peer-reviewed publications assessing the influence on outcomes in total hip and knee replacement of 7 preoperative risk factors-obesity, malnutrition, hypoalbuminemia, diabetes, anemia, smoking, and opioid use-and recommendations to mitigate them. Results: Sixty-nine studies were identified, including 3 randomized controlled trials, 8 prospective cohort studies, 42 retrospective studies, 6 systematic reviews, 3 narrative reviews, and 7 consensus guidelines. These studies described worse outcomes associated with these 7 risk factors, including increased rates of in-hospital complications, transfusions, periprosthetic joint infections, revisions, and deaths. Recommendations for strategies to screen and address these risk factors are provided. Conclusions: Risk factors can be optimized, with evidence suggesting the following thresholds prior to surgery: a body mass index <40 kg/m2, serum albumin ≥3.5 g/dL, hemoglobin A1C ≤7.5%, hemoglobin >12.0 g/dL in women and >13.0 g/dL in men, and smoking cessation and ≥50% decrease in opioid use by 4 weeks prior to surgery. Surgery should be delayed until these risk factors are adequately optimized.

Abstract
BACKGROUND This study aims to: 1) Determine the prevalence of preoperative anemia in arthroplasty; 2) Assess whether preoperative anemia is associated with inferior outcomes; and 3) Ascertain whether optimization in a dedicated blood management program (BMP) is associated with improved outcomes. METHODS All primary arthroplasties performed at an academic, tertiary-care, arthroplasty center between 2012 and 2017 were reviewed. Hemoglobin level obtained in the preoperative assessment clinic was recorded. Patients with anemia were then considered for further review in BMP. Outcomes included improvement in hemoglobin level post-BMP; length of stay; perioperative transfusion; 90-day readmission, complication, and reoperation rates. The effect of preoperative anemia and the effect of treatment at the BMP on outcomes were evaluated through multivariable regression analysis controlling for relevant covariates. RESULTS 17% of patients (932/5384) were found to have anemia; 115/357 patients who attended the BMP were no longer anemic. Thus, at time of operation, 15% of patients (817/5384) had anemia. Anemic patients were 4.09 times more likely (95% CI: 2.64-6.35) to require a transfusion; 1.42 times more likely (95% CI: 0.99-2.03) to sustain complications and had 19% longer (95% CI: 13%-26%) length of stay. Those who attended the BMP were less likely to receive a transfusion (OR = 0.32, 95% CI: 0.16-0.66), suffer from postoperative complications (OR = 0.30, 95% CI: 0.14-0.63), or require readmission compared with anemic patients not seen in the BMP (OR = 0.25, 95% CI: 0.09-0.71). CONCLUSIONS The prevalence of anemia in this arthroplasty cohort was 15%. Preoperative, timely, optimization of anemia should be strongly considered as it is likely to reduce "anemia-associated burden" after arthroplasty.

Implementation and results of an enhanced recovery (fast-track) program in total knee replacement patients at a French university hospital. Orthop Traumatol Surg Res 2021; 107:102851. [PMID: 33578042 DOI: 10.1016/j.otsr.2021.102851] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/01/2020] [Revised: 10/05/2020] [Accepted: 10/12/2020] [Indexed: 02/03/2023]
Abstract
INTRODUCTION In total knee replacement (TKR) surgeries, "fast-track" or enhanced recovery after surgery (ERAS) programs are being developed, but their impact on care pathway quality and safety has not been fully explored in the French literature. The present study aimed to compare results in TKR between fast-track and conventional pathways, addressing the following questions: (1) Are 90-day rates of complications, readmission and surgical revision higher with fast-track? (2) Is mean length of stay (LoS) shorter with fast-track? (3) Are postoperative pain and clinical results improved by fast-track? And, (4) are patients and care staff satisfied with these new programs? HYPOTHESIS Implementing fast-track for TKR in a university hospital center is beneficial for the patient and does not impair the quality and safety of care. PATIENTS AND METHOD A case-control study was performed using a retrospective analysis of prospectively collected data. A fast-track program was implemented for TKR by modifying the care pathway. This involved instituting a therapeutic education consultation, optimizing blood sparing, modifying surgical practices, and hastening early mobilization thus actively involving patients in their own management. Between January 2017 and January 2019, 216 patients with a mean age of 69.23±7.80years and mean BMI of 30.15±4.79kg/m2 were included in the fast-track group, with 335 matched patients included in the conventional group. RESULTS At 90days, there were no significant inter-group differences in rates of infection (fast-track=1.39%, conventional=0.90%; p=0.34), readmission (fast-track=3.24%, conventional=3.58%; p=0.49), or surgical revision (fast-track=2.78%, conventional=2.69%; p=0.298). The visual analog scale (VAS) pain rating was 1.56±1.36 in the fast-track group versus 5±2.41 in the conventional group; p<0.001. LoS was 3.17±1.59days in fast-track versus 7.25±1.85days in the conventional group; p<0.001. Ninety-five percent of patients and 96% of care staff were satisfied with the fast-track program. DISCUSSION Fast-track implementation ensured quality and safety of care; it did not increase the rate of complications in primary TKR. Mean length of stay was drastically reduced. Both patients and care staff were very satisfied with these new procedures. LEVEL OF EVIDENCE III; case-control study.

Factors Associated With Perioperative Transfusion in Lower Extremity Revision Arthroplasty Under a Restrictive Blood Management Protocol. J Am Acad Orthop Surg 2021; 29:e404-e409. [PMID: 32852330 DOI: 10.5435/jaaos-d-20-00185] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/04/2020] [Accepted: 07/18/2020] [Indexed: 02/01/2023] Open
Abstract
INTRODUCTION Approximately 37% of patients undergoing lower extremity revision total joint arthroplasty (TJA) receive allogeneic blood transfusions (ABTs), which are associated with increased risk of morbidity and death. It is important to identify patient factors associated with needing ABT because the health of higher-risk patients can be optimized preoperatively and their need for ABT can be minimized. Our goal was to identify the patient and surgical factors independently associated with perioperative ABT in revision TJA. METHODS We included all 251 lower extremity revision TJA cases performed at our academic tertiary care center from January 1, 2016, to December 31, 2018. We assessed the following factors for associations with perioperative ABT: patient age, sex, race, body mass index, preoperative hemoglobin level, and infection status (ie, infection as indication for revision TJA); use of vasopressors, tranexamic acid (TXA), surgical drains, tourniquets, and intraoperative cell salvage; and procedure type (hip versus knee), procedure complexity (according to the number of components revised), and surgical time. Multivariable regression was used to identify factors independently associated with perioperative ABT. RESULTS The following characteristics were independently associated with greater odds of perioperative ABT: preoperative hemoglobin level (odds ratio [OR], 1.8; 95% confidence interval [CI], 1.5 to 2.2), infectious indication for revision (OR, 3.6; 95% CI, 1.3 to 9.7), and procedure complexity. TXA use was a negative predictor of ABT (OR, 0.47; 95% CI, 0.23 to 0.98). Compared with polyethylene liner exchanges, single-component revisions (OR, 14; 95% CI, 3.6 to 56) and dual-component revisions (OR, 7.8; 95% CI, 2.3 to 26) were associated with greater odds of ABT. DISCUSSION Patients with preoperative anemia, those undergoing revision TJA because of infection, those who did not receive TXA, and those undergoing more complex TJA procedures may have greater odds of requiring ABT. We recommend preoperative optimization of the health of these patients to reduce the need for ABT. LEVEL OF EVIDENCE Level III, prognostic study.

Abstract
BACKGROUND Anemia is associated with poor outcome after major joint replacement surgery, but it is unclear whether sex and race modify its impact on outcome. We hypothesized that anemia would be associated with increased morbidity or mortality after knee arthroplasty surgery and that sex and race would be effect modifiers for this relationship. STUDY DESIGN AND METHODS We performed a retrospective cohort study of elective knee arthroplasty patients between 2013 and 2018 using data from the National Surgical Quality Improvement Program. Morbidity or mortality after surgery was compared between patients without anemia, with mild anemia, and with moderate to severe anemia. Multivariable logistic regression was used to determine adjusted odds for morbidity or mortality with anemia. Interaction terms were entered into the model to test for effect modification by sex and race. RESULTS 243 491 patients were included and 30 135 patients (12.4%) were anemic. Morbidity or mortality occurred in 3.7% of patients without anemia, 5.2% of patients with mild anemia, and 7.1% of patients with moderate to severe anemia (P < .001). After adjustment for confounding variables, mild anemia OR = 1.36 (95% CI = 1.28-1.45), and moderate to severe anemia OR = 1.92 (95% CI = 1.72-2.13) were associated with increased odds of morbidity or mortality. Sex, but not race, was a significant effect modifier with men having a greater increase in morbidity or mortality when anemic (P = .02). CONCLUSIONS Anemia is associated with increased morbidity or mortality after knee arthroplasty surgery and men have a greater increase in perioperative risk than women when anemic.

Abstract
OBJECTIVES To study the significance of checking post-operative hemoglobin and hematocrit following unicompartmental knee arthroplasty (UKA). SETTING Single center. Multiple surgeons. DESIGN Retrospective case series. Level of evidence IV. MATERIALS AND METHODS Following institutional approval, a retrospective analysis of all patients undergoing UKA at our level one academic university hospital was conducted. Operative records of all patients undergoing primary UKA were reviewed between March 2016 and March 2019. Patients' pre-operative hemoglobin and hematocrit, BMI, co-morbidities, application of tourniquet, tourniquet time, administration of tranexamic acid, need for post-operative blood transfusion, hospital length of stay, complications, and re-admission were all recorded. Blood loss was estimated using the post-operative hematocrit. RESULTS A total number of 155 patients were included. There were 70 females (45%) and 85 males (55%). The mean age was 66 ± 10 years. Median pre-op blood volume was 4700 mLs (interquartile range (IQR); 4200-5100). Median blood loss was 600 mLs (IQR; 400-830). Mean pre-op hemoglobin was 135 ± 14 g/L and mean post-op hemoglobin was 122 ± 13 g/L. No patient had a post-op hemoglobin under 80 g/L (range 93-154). No patients in our study needed transfusion. CONCLUSION The results of our study indicated that post-operative hemoglobin and hematocrit check proved unnecessary in all of our patients and could have been omitted from post-operative routines. We conclude that routine post UKA check of hemoglobin and hematocrit can be avoided and be saved for special circumstances depending on patient's physiology.

Abstract
Total blood loss from primary total knee arthroplasty may exceed 2 L with greater blood loss during revision procedures. Blood loss and allogeneic transfusion are strongly associated with adverse outcomes from surgery including postoperative mortality, thromboembolic events and infection. Strategies to reduce blood loss and transfusion rates improve patient outcomes and reduce healthcare costs. Interventions are employed preoperatively, intraoperatively and postoperatively. The strongest predictor for allogeneic blood transfusion is preoperative anaemia. Over 35% of patients are anaemic when scheduled for primary and revision knee arthroplasty, defined as haemoglobin <130 g/L for men and women, and the majority of cases are secondary to iron deficiency. Early identification and treatment of anaemia can reduce postoperative transfusions and complications. Anticoagulation must be carefully managed perioperatively to balance the risk of thromboembolic event versus the risk of haemorrhage. Intraoperatively, tranexamic acid reduces blood loss and is recommended for all knee arthroplasty surgery; however, the optimal route, dose or timing of administration remains uncertain. Cell salvage is a valuable adjunct to surgery with significant expected blood loss, such as revision knee arthroplasty. Autologous blood donation is not recommended in routine care, sealants may be beneficial in select cases but further evidence of benefit is required, and the use of a tourniquet remains at the discretion of the surgeon. Postoperatively, restrictive transfusion protocols should be followed with a transfusion threshold haemoglobin of 70 g/L, except in the presence of acute coronary syndrome. Recent studies report no allogeneic transfusions after primary knee arthroplasty surgery after employing blood conservation strategies. The current challenge is to select and integrate different blood conserving interventions to deliver an optimal patient pathway with a multidisciplinary approach.

Recent Trends in Blood Utilization After Revision Hip and Knee Arthroplasty. J Arthroplasty 2017; 32:3693-3697. [PMID: 28951054 DOI: 10.1016/j.arth.2017.08.038] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/09/2017] [Revised: 07/25/2017] [Accepted: 08/24/2017] [Indexed: 02/01/2023] Open
Abstract
BACKGROUND Blood transfusion guidelines in elective surgery have been implemented over the last decade to minimize risk and cost related to transfusion without sacrificing patient outcomes. Blood utilization in primary total hip (THA) and total knee arthroplasty (TKA) has been extensively studied but there is a paucity of studies evaluating utilization in revision THA and TKA. The purpose of this study is to evaluate current trends in transfusion following revision THA and TKA. METHODS The Humana dataset was reviewed for transfusion trends from 2007 to 2015 for patients undergoing revision THA and TKA. Subgroup analysis was performed to evaluate the impact of age, gender, geographic location, and obesity. RESULTS In total, 9176 and 12,493 revision THA and TKA patients were analyzed with transfusion rates of 19.2% and 11.9%, respectively. Allogeneic packed red blood cells were most commonly transfused (90% and 92%, respectively). Transfusion rates decreased significantly from 24.7% to 10.3% and 15.9% to 4.5%, respectively, over the years 2007-2015. Women had higher transfusion rates (odds ratio [OR] THA:TKA 1.24:1.23), while obesity was associated with lower transfusion rates after revision THA (OR 0.88). Transfusion rates were higher in 2-component revisions compared to primary (OR THA:TKA 1.24:1.24), while 1-component revisions had lower transfusion rates than primary procedures (OR THA:TKA 0.79:0.25). CONCLUSION Transfusion rates after revision THA and TKA have fallen substantially since 2007. In 2016, only 10% and 4% of revision THA and TKA, respectively, required transfusion. The study should provide benchmark data for surgeons to use as comparison to the blood utilization following revision joint replacement at their institutions.
