Global, regional, national trends of femur fracture and machine learning prediction: Comprehensive findings and questions from global burden of disease 1990-2019. J Orthop Translat 2024; 46:46-52. [PMID: 38800094 PMCID: PMC11127185 DOI: 10.1016/j.jot.2024.03.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/16/2024] [Revised: 02/23/2024] [Accepted: 03/08/2024] [Indexed: 05/29/2024] Open
Abstract
Background Femur fracture is a type of fracture with high disability and mortality. There is no comprehensive analysis and prediction of the global distribution of femur fractures, so we conducted this study. Methods Age-standardized incidence rate (ASIR), age-standardized prevalence rate (ASPR), and years living with disability (YLDs) of femur fractures (excluding femoral neck) were downloaded from the Global burden of disease database. Trend analysis was performed, and 6 time-series machine learning algorithms were applied to predict the global ASIR, ASPR, and YLDs. Results ASPR for femur fracture had been increasing in most countries worldwide from 1990 to 2019, with the highest in East Asia (AAPC = 1.25 95%Confidence Interval (1.2, 1.3)) and lowest in Central Latin America (AAPC = -0.74 95%CI (-0.81, -0.67)). However, ASIR showed a significant downward trend worldwide, with East Saharan Africa decreasing the most (AAPC = -4.04 95%CI (-5.56, -2.47)), and East Asia elevating the most (AAPC = 1.11 95%CI (0.87, 1.42)). YLDs were increasing over the world, with East Asia still elevating the most AAPC= (3.9 95%CI (3.85, 3.95)), with the only region of decrease being Eastern Europe (AAPC = -0.28 95%CI (-0.3, -0.26)). Both ASPR and ASIR were higher in women than in men in the >75 year group, whereas YLDs was lower in women than in men in the >60 year group. Globally, the ARIMA model was optimal in the prediction of ASPR, the PROPHET model effected in the prediction of ASIR, and the PROPHET WITH XGBOOST model was the best in the prediction of YLDs. The projections showed increase in both ASPR and YLDs, except for ASIR decreasing by 2030. Conclusions Our study found a rise in femur fracture ASPR and ASIR from 1990 to 2019 in war conflict areas and East Asia, meanwhile, the YLDs of femur fracture increased in populous countries. In both 1990 and 2019, both ASPR and ASIR were higher in women over 75 years than that in men, but YLDs was higher in men over 60 years than that in women. In 2020-2030, while global femur fracture ASIR might decline, both ASPR and YLDs might rise. The Translational Potential of this article Femur fracture is a high-energy injury due to direct violence, and in war, conflicting and underdeveloped regions such as East Asia. Accidental injuries may occur due to the rapid development of industry and the frequent traffic accidents. This study suggests that we should focus on elderly women (≥75 years) in the above regions in the future. For older men (>60 years old), more attention should be paid to post-fracture functional rehabilitation and early reintegration into society to reduce the disability rate and lower the socio-economic burden.

Abstract
PURPOSE Intensified acute in-hospital physiotherapy (IP) after hip fracture (HF) may enhance patient's ability to regain basic mobility at discharge. The primary objective was to assess the feasibility of IP. Secondary to estimate the effect of IP on regained basic mobility at discharge. MATERIALS AND METHODS In a pragmatic, randomized, unblinded feasibility trial, 60 patients (mean age 79 years, 41 women) with HF and an independent pre-fracture basic mobility level were randomized (2:1) to IP with two daily sessions on weekdays focusing on functional training and weight-bearing activities (n = 40) versus usual care (UC) physiotherapy once daily (n = 20). Feasibility outcomes included physiotherapy completion rates, reasons for non-successful completion, and adverse events. The primary effect outcome was recovery of basic mobility (Cumulated Ambulation Score (CAS)). RESULTS Eighty-two percent of the sessions in the IP group were successfully- or partially completed versus 94% of the sessions in the UC group. No adverse events occurred. The main reason for not completing physiotherapy was fatigue. At discharge (median 7 days), 50% in the IP group had regained their pre-fracture basic mobility level (CAS = 6) versus 16% in the UC group; odds ratio = 5.33, 95%CI [1.3;21.5]. CONCLUSIONS IP seems feasible for patients after HF surgery, and it may enhance recovery. Fatigue was the primary obstacle to completing IP.

Abstract
BACKGROUND Meta-analyses of randomized controlled trials (RCTs) evaluating thresholds for red blood cell (RBC) transfusion typically focus on mortality; however, other outcomes are highly relevant. The aim of this study is to summarize the effects of different transfusion thresholds on the outcomes of quality of life (QoL) and function. STUDY DESIGN We extracted data from RCTs identified in a recently published Cochrane systematic review. Primary analysis was descriptive. RESULTS A total of 23 RCTs with 13,743 adult participants were included. Fifteen RCTs included patients in the postoperative period, of which 9 RCTs were conducted in hip (n = 3024) and 6 (n = 8672) in cardiac surgeries; 5 RCTs (n = 489) were in patients with hematological malignancies; 2 in the setting of bleeding (gastrointestinal bleed [n = 936] and postpartum [n = 521]); and one RCT (n = 936) included critically ill patients. QoL and function were reported using a variety of questionnaires and tools. The timing of assessments varied between trials. No clear clinical differences in QoL outcomes were identified in comparisons between restrictive and liberal transfusion thresholds. DISCUSSION There is no evidence that a liberal transfusion strategy improves QoL and functional outcomes. However, the substantial limitations of many included studies indicate the need for further well-designed and adequately powered trials.

Abstract
Perioperative allogenic blood transfusions for patients with hip fractures are associated with increased costs and complications. This prospective randomized controlled trial evaluated whether tranexamic acid (TXA) reduces blood transfusion rates and blood loss in extracapsular hip fractures, when administered at the time of hospital admission. Patients with closed intertrochanteric or subtrochanteric femur fractures undergoing intramedullary nailing (n=100) were enrolled from October 2015 to January 2019. On arrival to the hospital, patients were randomized to receive either 1 g of intravenous TXA or normal saline. Blood transfusion rates from hospital arrival to postoperative day 5 or discharge, blood loss from hospital arrival to postoperative day 3 or 4, intraoperative blood loss, length of hospital stay, 30-day mortality, and major complications were evaluated. Six patients from the TXA group and five from the placebo group were excluded because of canceled surgery, study drug infusion after incision, multiple fractures, or dropout. Patient characteristics were similar between the groups. Postoperative transfusion rates were 17.5% (7 of 40) in the TXA group and 36.7% (18 of 49) in the placebo group (relative risk, 0.48; 95% CI, 0.22-1.03; P=.046). Total blood loss was significantly less in the TXA group (mean difference, 367 mL; 95% CI, 76-657; P=.01). No significant differences were found for intraoperative blood loss, length of hospital stay, 30-day mortality, or 30-day major complications. TXA administered on hospital arrival decreased the risk of postoperative blood transfusion and mean perioperative blood loss in patients with extracapsular hip fractures. We recommend a single-dose intravenous administration of TXA at the time of hospital admission for patients with extracapsular hip fractures. [Orthopedics. 2023;46(5):e303-e309.].

Abstract
BACKGROUND Perioperative interventions could enhance early mobilisation and physical function after hip fracture surgery. OBJECTIVE Determine the effectiveness of perioperative interventions on early mobilisation and physical function after hip fracture. METHODS Ovid MEDLINE, CINAHL, Embase, Scopus and Web of Science were searched from January 2000 to March 2022. English language experimental and quasi-experimental studies were included if patients were hospitalised for a fractured proximal femur with a mean age 65 years or older and reported measures of early mobilisation and physical function during the acute hospital admission. Data were pooled using a random effect meta-analysis. RESULTS Twenty-eight studies were included from 1,327 citations. Studies were conducted in 26 countries on 8,192 participants with a mean age of 80 years. Pathways and models of care may provide a small increase in early mobilisation (standardised mean difference [SMD]: 0.20, 95% confidence interval [CI]: 0.01-0.39, I2 = 73%) and physical function (SMD: 0.07, 95% CI 0.00 to 0.15, I2 = 0%) and transcutaneous electrical nerve stimulation analgesia may provide a moderate improvement in function (SMD: 0.65, 95% CI: 0.24-1.05, I2 = 96%). The benefit of pre-operative mobilisation, multidisciplinary rehabilitation, recumbent cycling and clinical supervision on mobilisation and function remains uncertain. Evidence of no effect on mobilisation or function was identified for pre-emptive analgesia, intraoperative periarticular injections, continuous postoperative epidural infusion analgesia, occupational therapy training or nutritional supplements. CONCLUSIONS Perioperative interventions may improve early mobilisation and physical function after hip fracture surgery. Future studies are needed to model the causal mechanisms of perioperative interventions on mobilisation and function after hip fracture.

Abstract
OBJECTIVE Hip fractures are common and significantly impact mobility and physical function. Measurement of patient progress post hip fracture in the acute hospital setting is important to monitor early recovery and outcomes. The objective of this systematic review was to assess the measurement properties (reliability, validity, responsiveness), interpretability, and clinical utility of instruments used to measure mobility and physical function in patients with hip fracture in the acute hospital setting. METHODS Three databases (MEDLINE, Embase, and CINAHL) were searched. Studies reporting direct clinician assessment instruments to measure mobility or physical function in patients with hip fracture were included. Data were extracted by 2 reviewers, and the quality of each study was determined using the COnsensus-based Standards for the selection of health Measurement INstruments risk of bias checklist. RESULTS Sixty-eight studies were included with 19 measurement instruments identified. The most frequently used instruments were the Timed "Up & Go" Test (TUG) (19 studies), Barthel Index (BI) (18 studies), Cumulated Ambulation Score (CAS) (18 studies), and Functional Independence Measure (FIM) (14 studies). All 4 of these instruments demonstrated good predictive validity (clinical outcomes and mortality) and responsiveness over time (effect sizes 0.63-2.79). The BI and CAS also had good reliability (intraclass correlation coefficient [ICC] >0.70). Floor effects were demonstrated for the TUG, CAS, and FIM (16%-60% of patients). The TUG, CAS, and BI all had good clinical utility. CONCLUSION Depending on the context (use by treating clinicians, research, benchmarking), 1 or a combination of the BI, CAS, and TUG provide robust measurement of mobility and physical function for patients with hip fracture in the acute hospital setting. IMPACT This study identified 3 instruments suitable for measuring mobility and physical function in hospitalized patients following hip fracture. This provides clinicians with tools to measure patient progress and benchmark across sites to improve patient outcomes.

Generating real-world evidence compatible with evidence from randomized controlled trials: a novel observational study design applicable to surgical transfusion research. BMC Med Res Methodol 2022; 22:312. [PMID: 36474137 PMCID: PMC9724333 DOI: 10.1186/s12874-022-01787-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2022] [Accepted: 11/08/2022] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND Numerous observational studies have revealed an increased risk of death and complications with transfusion, but this observation has not been confirmed in randomized controlled trials (RCTs). The "transfusion kills patients" paradox persists in real-world observational studies despite application of analytic methods such as propensity-score matching. We propose a new design to address this long-term existing issue, which if left unresolved, will be deleterious to the healthy generation of evidence that supports optimized transfusion practice. METHODS In the new design, we stress three aspects for reconciling observational studies and RCTs on transfusion safety: (1) re-definition of the study population according to a stable hemoglobin range (gray zone of transfusion decision; 7.5-9.5 g/dL in this study); (2) selection of comparison groups according to a trigger value (last hemoglobin measurement before transfusion; nadir during hospital stay for control); (3) dealing with patient heterogeneity according to standardized mean difference (SMD) values. We applied the new design to hospitalized older patients (aged ≥60 years) undergoing general surgery at four academic/teaching hospitals. Four datasets were analyzed: a base population before (Base Match-) and after (Base Match+) propensity-score matching to simulate previous observational studies; a study population before (Study Match-) and after (Study Match+) propensity-score matching to demonstrate effects of our design. RESULTS Of 6141 older patients, 662 (10.78%) were transfused and showed high heterogeneity compared with those not receiving transfusion, particularly regarding preoperative hemoglobin (mean: 11.0 vs. 13.5 g/dL) and intraoperative bleeding (≥500 mL: 37.9% vs. 2.1%). Patient heterogeneity was reduced with the new design; SMD of the two variables was reduced from approximately 100% (Base Match-) to 0% (Study Match+). Transfusion was related to a higher risk of death and complications in Base Match- (odds ratio [OR], 95% confidence interval [CI]: 2.68, 1.86-3.86) and Base Match+ (2.24, 1.43-3.49), but not in Study Match- (0.77, 0.32-1.86) or Study Match+ (0.66, 0.23-1.89). CONCLUSIONS We show how choice of study population and analysis could affect real-world study findings. Our results following the new design are in accordance with relevant RCTs, highlighting its value in accelerating the pace of transfusion evidence generation and generalization.

Abstract
Aims The aim of this study was to examine perioperative blood transfusion practice, and associations with clinical outcomes, in a national cohort of hip fracture patients. Methods A retrospective cohort study was undertaken using linked data from the Scottish Hip Fracture Audit and the Scottish National Blood Transfusion Service between May 2016 and December 2020. All patients aged ≥ 50 years admitted to a Scottish hospital with a hip fracture were included. Assessment of the factors independently associated with red blood cell transfusion (RBCT) during admission was performed, alongside determination of the association between RBCT and hip fracture outcomes. Results A total of 23,266 individual patient records from 18 hospitals were included. The overall rate of blood transfusion during admission was 28.7% (n = 6,685). There was inter-hospital variation in transfusion rate, ranging from 16.6% to 37.4%. Independent perioperative factors significantly associated with RBCT included older age (90 to 94 years, odds ratio (OR) 3.04 (95% confidence interval (CI) 2.28 to 4.04); p < 0.001), intramedullary fixation (OR 7.15 (95% CI 6.50 to 7.86); p < 0.001), and sliding hip screw constructs (OR 2.34 (95% CI 2.19 to 2.50); p < 0.001). Blood transfusion during admission was significantly associated with higher rates of 30-day mortality (OR 1.35 (95% CI 1.19 to 1.53); p < 0.001) and 60-day mortality (OR 1.54 (95% CI 1.43 to 1.67); p < 0.001), as well as delays to postoperative mobilization, higher likelihood of not returning to their home, and longer length of stay. Conclusion Blood transfusion after hip fracture was common, although practice varied nationally. RBCT is associated with adverse outcomes, which is most likely a reflection of perioperative anaemia, rather than any causal effect. Use of RBCT does not appear to reverse this effect, highlighting the importance of perioperative blood loss reduction. Cite this article: Bone Joint J 2022;104-B(11):1266–1272.

Abstract
INTRODUCTION We investigated the risk factors that increased the frequency of blood transfusions in elderly patients with intertrochanteric hip fractures to determine blood transfusion risk before surgery and to take selective precautionary measures in the group at high risk for transfusion to ensure safe surgery. MATERIALS AND METHODS We retrospectively reviewed the electronic medical records of 203 patients who underwent surgical fixation of intertrochanteric hip fractures from January 2015 to December 2020. We hypothesized that patient sex, age, body mass index, preoperative hemoglobin, preoperative platelet count, glomerular filtration rate (GFR), preoperative albumin level, American Society of Anesthesiologist score, intraoperative blood loss, duration of surgery, method of anesthesia, and time from injury to surgery would affect the need for blood transfusion. Student's t-test, Chi-squared test, and the one-way analysis of variance test were used to determine whether differences between variables in the transfusion and non-transfusion groups were significant. RESULTS Unstable fractures (P = 0.002), general anesthesia (P = 0.028), lower preoperative hemoglobin levels (P < 0.001), and lower GFRs (P < 0.001) were identified as related to blood transfusions in univariate analysis. In multivariate logistic analysis, the need for allogeneic blood transfusion in unstable fractures was approximately 2.949 times higher than in stable fractures (P = 0.009). The risk in general anesthesia patients was about 2.953 times higher than in spinal anesthesia patients (P = 0.007). In addition, the need for allogeneic blood transfusion increased by about 1.293 times as preoperative hemoglobin levels decreased by 1 g/dL (P = 0.017) and increased by about 1.017 times as the GFR decreased by 1 mL/min/1.7m2 (P = 0.006). CONCLUSION Low preoperative hemoglobin levels, low GFRs, general anesthesia, and unstable fractures in elderly patients with intertrochanteric hip fractures increased the risk of blood transfusion.

Effect of integrated management bundle on 1-year overall survival outcomes and perioperative outcomes in super elderly patients aged 90 and over with hip fracture: non-concurrent cohort study. BMC Musculoskelet Disord 2022; 23:778. [PMID: 35971104 PMCID: PMC9377134 DOI: 10.1186/s12891-022-05720-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/01/2022] [Accepted: 07/29/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Due to concomitant factors like frailty and comorbidity, super elderly (≥90 years) patients with hip fracture differ from patients aged 65-89 years in perioperative complications and mortality. The integrated management bundle referred to bundled application of multiple clinical measures. The aim of this study was to analyze effect of integrated management bundle on 1-year overall survival and perioperative outcomes in super elderly patients with hip fracture, with multidisciplinary management group serving as the control group. METHODS In this retrospective cohort study, super elderly patients with hip fracture were included from Jan 2017 to Nov 2020. Patients were retrospectively divided to multidisciplinary management group and integrated management bundle group. The primary outcome was 1- year overall survival, and the secondary outcome was perioperative outcomes. Kaplan-Meier methods was used to compare survival probability. Multivariable Cox's modeling was used to explain the effect of integrated bundle on 1-year overall survival adjusted for confounders. The perioperative outcomes including complications and in-hospital data of two groups were compared. The multivariable logistic regression was used to explain the effect of integrated bundle on the occurrence of perioperative complications adjusted for confounders. Prognostic factors related to survival was identified by multivariable Cox's regression analysis. RESULTS Ninety-seven patients comprised multidisciplinary management group, and 83 comprised integrated management bundle group. The Kaplan-Meier plots showed that the survival probability of integrated management bundle group was significantly better than multidisciplinary management group (HR:0.435, 95%CI:0.207-0.914, P = 0.039). Multivariable analysis after adjustment for confounders showed a 42.8% lower incidence of mortality integrated management bundle group than multidisciplinary management group (HR:0.428, 95%CI:0.186-0.986, P = 0.046). Incidence of hypoproteinemia, and electrolyte disturbance in integrated management bundle group was significantly lower than multidisciplinary management group (all P < 0.05). In addition, significant reduction was observed in length of stay (P < 0.05) in integrated management bundle group. Multivariable logistic regression showed integrated management bundle was independent protective factor of hypoproteinemia, and electrolyte disturbance. mECM score ≥ 6 and ASA score > 2 were independent risk factors of overall survival (HR: 1.940, 95%CI: 1.067-3.525,P = 0.030; HR: 2.281, 95%CI: 1.113-4.678,P = 0.024). CONCLUSIONS The integrated management bundle improved 1-year overall survival and played positive effects in improving perioperative outcomes. It might be a more suitable management modality for super elderly patients with hip fracture.

Abstract
BACKGROUND Preoperative resuscitation strategies in patients with hip fracture (HF) are lacking. We aimed to investigate fluid-responsiveness, peripheral perfusion index (PPI) and blood volume (BV)-status in patients with HF undergoing resuscitation in the preoperative phase. METHODS In a prospective observational study, we evaluated preoperative fluid-responsiveness, indices of perfusion and BV before and after lumbar epidural analgesia in 50 patients with HF shortly after admittance. RESULTS Initially, 18 (36%) patients were fluid-responsive (≥10% increased SV in response to 250 ml fluid bolus) and 13 (26%) presented hypovolaemia (deviation of measured BV from estimated BV ≤ 0.9). According to fluid-responsiveness, no difference in absolute values of cardiac index (CI) (2.7 L [2.1-3.3] vs. 2.8 L [2.3-3.4], p = .5) was seen, but cardiac output (CO) rose significantly in the hypovolaemic patients: 9% [5-18] vs. 1% [-3-7], p = .004. After epidural analgesia, 26 (52%) patients were again fluid-responsive and 15 (30%) were hypovolaemic. CI was now significantly lower in fluid-responsive patients (2.2 L [1.7-2.7] vs. 2.9 L [2.3-3.5], p = .001). Prior to epidural analgesia, no significant trend towards hypovolaemic patients having lower indices of perfusion was seen. After epidural analgesia, more patients with hypovolaemia presented with PPI≤1.5 (8 (53%) vs. 3 (9%), p = .001) and absolute values of PPI were also significantly lower if IBV was low (1.4 [0.9-3.2] vs. 3.2 [2.4-4.8], p = .01). PPI correlated with hypovolaemia after epidural analgesia (rho 0.4 [0.1-0.7], p = .007). CONCLUSIONS Preoperative fluid-responsivity in HF patients might be attributable to elements of hypovolaemia and sympathetic compensatory ability conjointly, confounding the use of SV-guided resuscitation. PPI could be associated with BV, which may support clinicians during perioperative haemodynamic optimisation.

Abstract
BACKGROUND AND OBJECTIVES There is an ongoing controversy regarding the risks of restrictive and liberal red blood cell (RBC) transfusion strategies. This meta-analysis assessed whether transfusion at a lower threshold was superior to transfusion at a higher threshold, with regard to thrombosis-related events, that is, whether these outcomes can benefit from a restrictive transfusion strategy is debated. MATERIALS AND METHODS We searched PubMed, Cochrane Central Register of Controlled Trials and Scopus from inception up to 31 July 2021. We included randomized controlled trials (RCTs) in any clinical setting that evaluated the effects of restrictive versus liberal RBC transfusion in adults. We used random-effects models to calculate the risk ratios (RRs) and 95% confidence intervals (CIs) based on pooled data. RESULTS Thirty RCTs involving 17,334 participants were included. The pooled RR for thromboembolic events was 0.65 (95% CI 0.44-0.94; p = 0.020; I2 = 0.0%, very low-quality evidence), favouring the restrictive strategy. There were no significant differences in cerebrovascular accidents (RR = 0.83; 95% CI 0.64-1.09; p = 0.180; I2 = 0.0%, very low-quality evidence) or myocardial infarction (RR = 1.05; 95% CI 0.87-1.26; p = 0.620; I2 = 0.0%, low-quality evidence). Subgroup analyses showed that a restrictive (relative to liberal) strategy reduced (1) thromboembolic events in RCTs conducted in North America and (2) myocardial infarctions in the subgroup of RCTs where the restrictive transfusion threshold was 7 g/dl but not in the 8 g/dl subgroup (with a liberal transfusion threshold of 10 g/dl in both subgroups). CONCLUSIONS A restrictive (relative to liberal) transfusion strategy may be effective in reducing venous thrombosis but not arterial thrombosis.

Abstract
OBJECTIVE The objective of this work was to carry out a meta-analysis of RCTs comparing intraoperative RBC transfusion strategies to determine their impact on postoperative morbidity, mortality, and blood product use. SUMMARY OF BACKGROUND DATA RBC transfusions are common in surgery and associated with widespread variability despite adjustment for casemix. Evidence-based recommendations guiding RBC transfusion in the operative setting are limited. METHODS The search strategy was adapted from a previous Cochrane Review. Electronic databases were searched from January 2016 to February 2021. Included studies from the previous Cochrane Review were considered for eligibility from before 2016. RCTs comparing intraoperative transfusion strategies were considered for inclusion. Co-primary outcomes were 30-day mortality and morbidity. Secondary outcomes included intraoperative and perioperative RBC transfusion. Meta-analysis was carried out using random-effects models. RESULTS Fourteen trials (8641 patients) were included. One cardiac surgery trial accounted for 56% of patients. There was no difference in 30-day mortality [relative risk (RR) 0.96, 95% confidence interval (CI) 0.71-1.29] and pooled postoperative morbidity among the studied outcomes when comparing restrictive and liberal protocols. Two trials reported worse composite outcomes with restrictive triggers. Intraoperative (RR 0.53, 95% CI 0.43-0.64) and perioperative (RR 0.70, 95% CI 0.62-0.79) blood transfusions were significantly lower in the restrictive group compared to the liberal group. CONCLUSIONS Intraoperative restrictive transfusion strategies decreased perioperative transfusions without added postoperative morbidity and mortality in 12/14 trials. Two trials reported worse outcomes. Given trial design and generalizability limitations, uncertainty remains regarding the safety of broad application of restrictive transfusion triggers in the operating room. Trials specifically designed to address intraoperative transfusions are urgently needed.

Abstract
Objective
To compare the techniques for the osteosynthesis of intertrochanteric fractures with dynamic hip screws (DHSs) through the Hardinge and minimally-invasive access routes of the hip, evaluating the operative time, the degree of pain in the immediate postoperative period, the hematimetric loss, and the functional aspects of active mobility.
Methods
A randomized, double-blinded clinical trial in which 66 patients with intertrochanteric fractures were submitted to osteosynthesis by DHS. The patients were divided into a test group, submitted to the minimally-invasive access, and a control group, in whom the surgery was performed through the Hardinge route.
Results
Patients submitted to the minimally-invasive treatment presented a lower degree of postoperative pain compared to the group treated by the Hardinge lateral route (
p
< 0.001), as well as lower hematimetric loss (
p
< 0.001), shorter operative time (
p
< 0.001), and improvement in immediate postoperative active mobility tests (
p
<0.05).
Conclusion
The study demonstrated the clinical superiority of the minimally-invasive access route parameters analyzed in relation to the Hardinge access for the fixation of intertrochanteric fractures when DHS is the choice osteosynthesis method.

Pietris J. The effect of perioperative blood transfusion thresholds on patient outcomes in orthopaedic surgery: a literature review. ANZ J Surg 2022; 92:661-665.

Abstract
Blood transfusions are one of the most common interventions required perioperatively in orthopaedic patients. There exist two main schools of thought in relation to perioperative blood transfusion - transfusing at a haemoglobin level of 70 g/L or below (termed 'restrictive protocol' in the literature), versus transfusing at a haemoglobin threshold of 100 g/L (which the literature terms 'liberal'). Few reviews of the literature exist comparing the impact of different transfusion strategies on the postoperative outcomes of these orthopaedic patients. This review analyses the 11 currently available studies on transfusion protocols in orthopaedics and associated findings related to patient outcomes. The literature showed no clear consensus on whether one transfusion protocol is superior in the orthopaedic patient. There was strong evidence for reduced transfusion rates among groups receiving transfusion at <70 g/L, and hence a reduction in complication directly related to transfusions. Despite this, other measured patient outcomes, including length of stay, postoperative complication rate, and mortality rate, were unchanged between the groups. Some evidence exists that a Hb threshold of 100 g/L results in earlier postoperative ambulation in hip surgery patients. One study suggests using preoperative haemoglobin as a preoperative risk factor to aid in determining whether patients are more suited to one approach over the other. Further high-quality clinical trials in orthopaedic cohorts must become available to determine whether a haemoglobin threshold of 70 g/L can safely be adopted to reduce transfusion rates without adversely impacting patient outcomes.

Abstract
BACKGROUND The optimal haemoglobin threshold for use of red blood cell (RBC) transfusions in anaemic patients remains an active field of research. Blood is a scarce resource, and in some countries, transfusions are less safe than in others because of inadequate testing for viral pathogens. If a liberal transfusion policy does not improve clinical outcomes, or if it is equivalent, then adopting a more restrictive approach could be recognised as the standard of care. OBJECTIVES: The aim of this review update was to compare 30-day mortality and other clinical outcomes for participants randomised to restrictive versus liberal red blood cell (RBC) transfusion thresholds (triggers) for all clinical conditions. The restrictive transfusion threshold uses a lower haemoglobin concentration as a threshold for transfusion (most commonly, 7.0 g/dL to 8.0 g/dL), and the liberal transfusion threshold uses a higher haemoglobin concentration as a threshold for transfusion (most commonly, 9.0 g/dL to 10.0 g/dL). SEARCH METHODS We identified trials through updated searches: CENTRAL (2020, Issue 11), MEDLINE (1946 to November 2020), Embase (1974 to November 2020), Transfusion Evidence Library (1950 to November 2020), Web of Science Conference Proceedings Citation Index (1990 to November 2020), and trial registries (November 2020). We checked the reference lists of other published reviews and relevant papers to identify additional trials. We were aware of one trial identified in earlier searching that was in the process of being published (in February 2021), and we were able to include it before this review was finalised. SELECTION CRITERIA We included randomised trials of surgical or medical participants that recruited adults or children, or both. We excluded studies that focused on neonates. Eligible trials assigned intervention groups on the basis of different transfusion schedules or thresholds or 'triggers'. These thresholds would be defined by a haemoglobin (Hb) or haematocrit (Hct) concentration below which an RBC transfusion would be administered; the haemoglobin concentration remains the most commonly applied marker of the need for RBC transfusion in clinical practice. We included trials in which investigators had allocated participants to higher thresholds or more liberal transfusion strategies compared to more restrictive ones, which might include no transfusion. As in previous versions of this review, we did not exclude unregistered trials published after 2010 (as per the policy of the Cochrane Injuries Group, 2015), however, we did conduct analyses to consider the differential impact of results of trials for which prospective registration could not be confirmed. DATA COLLECTION AND ANALYSIS: We identified trials for inclusion and extracted data using Cochrane methods. We pooled risk ratios of clinical outcomes across trials using a random-effects model. Two review authors independently extracted data and assessed risk of bias. We conducted predefined analyses by clinical subgroups. We defined participants randomly allocated to the lower transfusion threshold as being in the 'restrictive transfusion' group and those randomly allocated to the higher transfusion threshold as being in the 'liberal transfusion' group. MAIN RESULTS A total of 48 trials, involving data from 21,433 participants (at baseline), across a range of clinical contexts (e.g. orthopaedic, cardiac, or vascular surgery; critical care; acute blood loss (including gastrointestinal bleeding); acute coronary syndrome; cancer; leukaemia; haematological malignancies), met the eligibility criteria. The haemoglobin concentration used to define the restrictive transfusion group in most trials (36) was between 7.0 g/dL and 8.0 g/dL. Most trials included only adults; three trials focused on children. The included studies were generally at low risk of bias for key domains including allocation concealment and incomplete outcome data. Restrictive transfusion strategies reduced the risk of receiving at least one RBC transfusion by 41% across a broad range of clinical contexts (risk ratio (RR) 0.59, 95% confidence interval (CI) 0.53 to 0.66; 42 studies, 20,057 participants; high-quality evidence), with a large amount of heterogeneity between trials (I² = 96%). Overall, restrictive transfusion strategies did not increase or decrease the risk of 30-day mortality compared with liberal transfusion strategies (RR 0.99, 95% CI 0.86 to 1.15; 31 studies, 16,729 participants; I² = 30%; moderate-quality evidence) or any of the other outcomes assessed (i.e. cardiac events (low-quality evidence), myocardial infarction, stroke, thromboembolism (all high-quality evidence)). High-quality evidence shows that the liberal transfusion threshold did not affect the risk of infection (pneumonia, wound infection, or bacteraemia). Transfusion-specific reactions are uncommon and were inconsistently reported within trials. We noted less certainty in the strength of evidence to support the safety of restrictive transfusion thresholds for the following predefined clinical subgroups: myocardial infarction, vascular surgery, haematological malignancies, and chronic bone-marrow disorders. AUTHORS' CONCLUSIONS Transfusion at a restrictive haemoglobin concentration decreased the proportion of people exposed to RBC transfusion by 41% across a broad range of clinical contexts. Across all trials, no evidence suggests that a restrictive transfusion strategy impacted 30-day mortality, mortality at other time points, or morbidity (i.e. cardiac events, myocardial infarction, stroke, pneumonia, thromboembolism, infection) compared with a liberal transfusion strategy. Despite including 17 more randomised trials (and 8846 participants), data remain insufficient to inform the safety of transfusion policies in important and selected clinical contexts, such as myocardial infarction, chronic cardiovascular disease, neurological injury or traumatic brain injury, stroke, thrombocytopenia, and cancer or haematological malignancies, including chronic bone marrow failure. Further work is needed to improve our understanding of outcomes other than mortality. Most trials compared only two separate thresholds for haemoglobin concentration, which may not identify the actual optimal threshold for transfusion in a particular patient. Haemoglobin concentration may not be the most informative marker of the need for transfusion in individual patients with different degrees of physiological adaptation to anaemia. Notwithstanding these issues, overall findings provide good evidence that transfusions with allogeneic RBCs can be avoided in most patients with haemoglobin thresholds between the range of 7.0 g/dL and 8.0 g/dL. Some patient subgroups might benefit from RBCs to maintain higher haemoglobin concentrations; research efforts should focus on these clinical contexts.

The application of patient-centered care bundle significantly reduces incidence of perioperative respiratory complications in hip fracture patients aged 80 and over. Geriatr Nurs 2021; 43:213-218. [PMID: 34929520 DOI: 10.1016/j.gerinurse.2021.11.014] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2021] [Revised: 11/19/2021] [Accepted: 11/20/2021] [Indexed: 01/07/2023]
Abstract
This study was designed as a pilot test to analyze the effect of patient-centered care (PCC) bundle intervention on perioperative respiratory complications and other outcomes in hip fracture patients aged ≥80. Between Jan 2018 and Dec 2019, 198 patients comprised the routine care group and 187 comprised the PCC bundle group. After propensity score matching, 151 remained in each group. Incidence of perioperative respiratory complications in the PCC bundle group was significantly lower than in the routine care group (all P < 0.05). Furthermore, significant reductions were observed in surgery delay, length of stay, incidence of arrhythmia, hypoproteinemia, and electrolyte disturbance (all P < 0.05) in the PCC bundle group. Age-Adjusted Charlson Comorbidity Index score was related, but only weakly, to length of stay and the number of perioperative complications. These results suggested that the PCC bundle might be a more suitable care modality for patients ≥80 with hip fracture.

Transfus Apher Sci 2021; 60:103277. [PMID: 34563458 DOI: 10.1016/j.transci.2021.103277] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2021] [Revised: 09/06/2021] [Accepted: 09/09/2021] [Indexed: 01/28/2023]
Abstract
OBJECTIVE The goal of this study was to predict the probability of transfusion of red blood cells and the volume of blood consumption based on the clinical characteristics of patients before surgery. METHODS The medical records of 565 patients over 65 years old who underwent posterior lumbar surgery and 586 patients over 65 years old receiving femoral fracture surgery were reviewed. The clinical characteristics of the patients were subjected to multivariate regression analysis. The scores of these factors' influences on intraoperative red blood cells infusion were based on the odds ratio of each multivariate risk factor. Non-linear regression was performed to predict the probability of intraoperative blood transfusion and the volume of blood used for patients with different scores. RESULTS The factors that significantly influenced blood use during lumbar spinal stenosis and femoral fracture surgery in aged patients(P < 0.05) included age, body mass index, abnormal coagulation function, preoperative hemoglobin, administration of antithrombotic drugs, multisegmental lesions of the lumbar spine, femoral shaft fracture, secondary lumbar surgery and the time from fracture to surgery exceeding 48 h. According to our risk scoring system, patients of posterior lumbar surgery scored 0-10 and patients of femoral fracture had a score of 0-12. More than 50 % of patients receiving an intraoperative red blood cells transfusion during surgery scored>1. CONCLUSION The scoring system can be used as a predictive model for the probability of red blood cells transfusion and the blood volume in aged patients undergoing lumbar spinal stenosis and femoral fracture surgeries.

Abstract
OBJECTIVES The objective of this work was to carry out a systematic review of clinical practice guidelines (CPGs) pertaining to intraoperative red blood cell (RBC) transfusions, in terms of indications, decision-making, and supporting evidence base. SUMMARY OF BACKGROUND DATA RBC transfusions are common during surgery and there is evidence of wide variability in practice. METHODS Major electronic databases (MEDLINE, EMBASE, and CINAHL), guideline clearinghouses and Google Scholar were systematically searched from inception to January 2019 for CPGs pertaining to indications for intraoperative RBC transfusion. Eligible guidelines were retrieved and their quality assessed using AGREE II. Relevant recommendations were abstracted and synthesized to allow for a comparison between guidelines. RESULTS Ten guidelines published between 1992 and 2018 provided indications for intraoperative transfusions. No guideline addressed intraoperative transfusion decision-making as its primary focus. Six guidelines provided criteria for transfusion based on hemoglobin (range 6.0-10.0 g/dL) or hematocrit (<30%) triggers. In the absence of objective transfusion rules, CPGs recommended considering other parameters such as blood loss (n = 7), signs of end organ ischemia (n = 5), and hemodynamics (n = 4). Evidence supporting intraoperative recommendations was extrapolated primarily from the nonoperative setting. There was wide variability in the quality of included guidelines based on AGREE II scores. CONCLUSION This review has identified several clinical practice guidelines providing recommendations for intraoperative transfusion. The existing guidelines were noted to be highly variable in their recommendations and to lack a sufficient evidence base from the intraoperative setting. This represents a major knowledge gap in the literature.

Abstract
OBJECTIVE It remains unclear whether transfusion strategies during orthopedic surgery and infection are related. The purpose of this study is to evaluate whether liberal blood transfusion strategies contribute to infection risk in orthopedic patients by analyzing randomized controlled trials (RCTs). METHODS RCTs with liberal versus restrictive red blood cell (RBC) transfusion strategies were identified by searching PubMed, Embase, the Cochrane Central Register of Controlled Trials from their inception to July 2019. Ten studies with infections as outcomes were included in the final analysis. According to the Jadad scale, all studies were considered to be of high quality. RESULTS Ten trials involving 3938 participants were included in this study. The pooled risk ratio (RR) for the association between liberal transfusion strategy and infection was 1.34 (95% confidence intervals [CI], 0.94-1.90; P = .106). The sensitivity analysis indicated unstable results, and no significant publication bias was observed. CONCLUSION This pooled analysis of RCTs demonstrates that liberal transfusion strategies in orthopedic patients result in a nonsignificant increase in infections compared with more restrictive strategies. The conclusions are mainly based on retrospective studies and should not be considered as recommendation before they are supported by larger scale and well-designed RCTs.

[PMID: 33467771 PMCID: PMC7839049 DOI: 10.3390/geriatrics6010008] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2020] [Revised: 01/05/2021] [Accepted: 01/12/2021] [Indexed: 12/20/2022] Open
Abstract
To examine if knee-extension strength (KES) measures indicating probable sarcopenia are associated with health-related outcomes and if KES and hand grip strength (HGS) measures are associated with 1-year mortality after hip fracture. Two groups of older patients with hip fracture had either HGS (n = 32) or KES (n = 150) assessed during their acute hospital stay. Cut-points for HGS (<27 kg for men and <16 kg for women), and cut-points for maximal isometric KES (non-fractured limb), being the lowest sex-specific quintile (<23.64 kg for men and <15.24 kg for women), were used to examine association with health-related outcomes and 1-year mortality. Overall, 1-year mortality was 12.6% in the two strength groups, of which 47% (HGS) and 46% (KES) respectively, were classified as probable sarcopenia. Probable sarcopenia patients (KES) had lower prefracture function, performed poorly in mobility measures and expressed a greater concern of falling compared to their stronger counterparts. Hazard ratio for 1-year mortality was 2.7 (95%CI = 0.49–14.7, p = 0.3) for HGS and 9.8 (95%CI = 2.2–43.0, p = 0.002) for KES for probable sarcopenia patients compared to those not. Sex-specific KES measures indicating sarcopenia is associated with health-related outcomes and a strong predictor of 1-year mortality after hip fracture.

Abstract
Purpose The aim of our study was to explore the risk factors related to blood transfusion after intramedullary nail fixation of elderly femoral intertrochanteric fracture (FTF) and establish a nomogram prediction model. Patients and Methods We conducted a retrospective study including elderly FTF patients treated by intramedullary nail between January 2017 and December 2019. Perioperative information was obtained retrospectively, uni- and multivariate regression analyses were performed to determine risk factors for blood transfusion. A nomogram model was established to predict the risk of blood transfusion, and consistency coefficient (C-index) and correction curve were used to evaluate the prediction performance and consistency of the model. Results Of 148 patients, 119 were finally enrolled in the study and and 46 patients (38.7%) received a blood transfusion after the operation. Logistic regression analysis the female, lower preoperative Hb, ASA score >2, general anesthesia, and higher intraoperative blood loss were independently associated with the blood transfusion. The accuracy of the contour map for predicting transfusion risk was 0.910. Conclusion These risk factors are shown on the nomogram and verified. Through the assessment of the risk of blood transfusion and the intervention of modifiable risk factors, we may be able to reduce the blood transfusion rate to a certain extent, so as to further guarantee the safety of the elderly patients during the perioperative period.

Abstract
OBJECTIVES Most patients can tolerate a hemoglobin (Hgb) > 8 g per deciliter. In some cases, however, transfusion will delay physical therapy and hospital discharge. This study aims to review Hgb and transfusion data for a large volume of recent hip fracture patients in order to identify new opportunities for decreasing the length of hospital stay. Our hypotheses are that in some cases, earlier transfusion of more blood will be associated with shorter hospital stays, and that Hgb levels consistently decrease for more than 3 days postoperatively. DESIGN Retrospective chart review. SETTING Two academic medical centers with Geriatric Fracture Programs. PATIENTS Data was collected from patients 50 years and older with hip fractures April 2015 and October 2017. INTERVENTION Operative stabilization of the hip fractures according to standard of care for the fracture type and patient characteristics. Transfusion according to established standards. MAIN OUTCOME MEASUREMENTS Electronic records were retrospectively reviewed for demographic information, Hgb levels, and transfusion events. RESULTS One thousand fifteen patients with femoral neck or intertrochanteric hip fractures were identified. Eight hundred sixty met the inclusion criteria. The average length of hospital stay was 6.7 days. The mean patient age was 82 years. The average American Society of Anesthesiologists score was 2.9. The average Hgb level consistently decreased for 5 days postoperatively before beginning to increase on day 6. There was poor consistency between intraoperative Hgb levels and preoperative or postoperative Hgb levels. Three hundred sixty-eight (42.8%) patients were transfused an average of 1.9 (range 1-6) units. One hundred five patients required a transfusion on postoperative day (POD) 1: 72 received only 1 unit of blood: 36 (50%) of the 72 required a second transfusion in the following days, compared to 9 of 33 (27%) who received 2 units on POD 1 (χ2 = 3.8898; P < .05). Patients who received transfusions on POD 3 or later had an average length of stay >2.5 days longer than those who received a transfusion earlier (P = 0.005). CONCLUSIONS Our findings do not support earlier transfusion of more blood. Although in some cases, there is an association between earlier transfusion of more blood and shorter hospital stay, routine transfusion of more blood would incur higher transfusion risks in some patients who would not otherwise meet criteria for transfusion. After hip fracture surgery, the Hgb usually decreases for 5 days and does not begin to increase until POD 6. This information will provide utility in the population health management of hip fracture patients. LEVEL OF EVIDENCE Level III, Retrospective Cohort Study.

Abstract
Background Literature has shown a significant correlation between early treatment and mortality in femur fractures, but the influence of time to ambulation on mortality has not been studied. The purpose of the present study is to evaluate whether time to ambulation is correlated to femur fracture mortality independently from time to surgery. Patients and methods All patients older than 65 years admitted at a level I trauma center with proximal femoral fracture during a 1-year period were included. The following data were collected: age, gender, date and time of admission to emergency department, height, weight, body mass index, type and side of fracture, ASA score, date and time of surgery, surgical time, time to ambulation, length of hospitalization, death during hospitalization, and mortality at 6 and 12 months. Results The study sample comprises 516 patients. The mean age was 83.6 years; ASA score was 3–5 in 53% of patients; 42.7% presented with medial fracture; mean time between admission and surgery was 48.4 h; 22.7% of patients were not able to walk during the first 10 days after fracture; mean duration of hospitalization was 13 days; and mortality was 17% at 6 months and 25% at 1 year. Early surgery and walking ability at 10 days after trauma were independently and significantly associated with mortality at 6 months (p = 0.014 and 0.002, respectively) and at 1 year (0.027 and 0.009, respectively). Conclusions Early surgery in femur fracture became a priority in health systems, but early postoperative physiotherapy also plays a major role in prevention of mortality: independently from surgical timing, patients who did not walk again within 10 days from surgery showed mortality rates higher than those of patients who did.

Abstract
A hemoglobin (Hb) threshold level of 7 g/dL has been proposed for red blood cell (RBC) transfusion in patients with chronic anemia in the Japanese guideline since 2005. However, Hb thresholds for hematological diseases in clinical practice and factors responsible for higher Hb thresholds remain unclear. Hb thresholds were collected for patients with hematological diseases from 32 Japanese teaching hospitals. Uni- and multivariate analyses were used to analyze relationships between Hb threshold level and various patient and hospital factors. In total, 4996 units of RBC were transfused to 1054 patients with hematological diseases in 2421 transfusions. Median age was 68 years. Myelodysplastic syndrome was the most frequent diagnosis. Overall median Hb threshold level was 6.9 g/dL. Multivariate linear regression analysis detected the following variables associated with Hb threshold level: hospital; cardiovascular disease; symptomatic anemia; and hematopoietic stem cell transplantation. Hospital was the most significant factor. Collectively, median Hb threshold level in clinical practice in Japan was similar to the guidelines. Higher Hb threshold level depended on the hospitals at which the transfusions were performed as well as patient condition. Educational approaches directed toward hospitals may be useful to promote transfusion guidelines.

Preoperative erythropoietin within a patient blood management program decreases both blood transfusion and postoperative anemia: a prospective observational study. Transfusion 2020; 60:1732-1740. [PMID: 32681743 DOI: 10.1111/trf.15900] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2020] [Revised: 04/27/2020] [Accepted: 04/27/2020] [Indexed: 01/28/2023]
Abstract
BACKGROUND In orthopedic surgery, a patient blood management program (PBM) has been proposed to reduce blood transfusion. The aim of this observational study was to assess, within a PBM, the specific efficacy of preoperative erythropoietin (EPO). STUDY DESIGN AND METHODS In a single hospital, 723 patients undergoing elective primary hip or knee arthroplasty were prospectively studied. The PBM included EPO if preoperative hemoglobin was lower than 13 g/dL, intraoperative administration of tranexamic acid, use of recommended transfusion thresholds, and postoperative infusion of iron. Blood transfusion and hemoglobin were noted until discharge. Major thromboembolic or cardiovascular events were assessed during admission and 1 month after discharge. RESULTS Transfusion was noted in 2.5% patients with EPO. Transfusion rate was higher in patient for whom EPO was not indicated (13.6% transfusion rate; odds ratio [OR], 13.7; 95% confidence interval [CI], 2.6-66; p = 10-3 ) or if erythropoietin was indicated but not administrated (36.8% transfusion rate; OR, 18.2; 95% CI, 3.9-84.5; p < 10-3 ). Hemoglobin was significantly higher during the postoperative period in patients with erythropoietin. At hospital discharge, 57% of patients were anemic if EPO was used compared to 88% when EPO was not indicated and 87% when EPO was indicated but not administered (p < 10-6 ). There were no significant differences in the odds of major complications between patients with or without EPO. CONCLUSIONS Within a PBM, preoperative treatment of anemia with EPO decreased both the rate of blood transfusion and postoperative anemia. Further studies are necessary to confirm these results.

Abstract
Background Prior literature has examined the association between preoperative anemia and complications across surgical settings; however, evidence is lacking for splenectomy patients. We investigated the association between preoperative hematocrit and 30-day postoperative outcomes in this population using a national database. Methods Patients who underwent splenectomy (2012–2017) were identified from the American College of Surgeons National Surgical Quality Improvement Program database. Analyses were performed for the overall cohort and elective versus emergent subsets, adjusting for transfusion among other covariates. Results Our sample included 5,580 patients. As hematocrit decreased, complication rates increased incrementally in both the univariate and multivariate analyses. Adjusted odds ratios (and 95% confidence intervals) for moderate anemia (26% ≤ hematocrit < 30%) as compared to no anemia (hematocrit ≥ 38%) were readmission = 1.5 (1.1–1.8), sepsis = 2.2 (1.6–3.0), and composite outcome = 1.8 (1.0–3.2). Parameter estimates (standard error, P value) for the moderate versus no anemia group were length of stay = 3.0 (0.5, P < .001) and days to discharge = 1.2 (0.3; P < .001). Conclusion Our results demonstrate a dose-response relationship between increasing degree of anemia and odds of various postoperative adverse outcomes after adjusting for several potential confounders. The subset analysis further suggests that elective splenectomy cases are more likely to have poor outcomes when in the presence of anemia or when transfusions are performed as compared to emergent cases. This suggests that the harm associated with transfusion may offset the benefit of optimizing anemia in an elective splenectomy case.

Abstract
This study aimed to discuss the risk factors of perioperative blood transfusion after the application of proximal femoral nail antirotation (PFNA) in the treatment of elderly patients with femoral intertrochanteric fracture (FIF). Moreover, this study also aimed to analyze the causes of perioperative blood transfusion and provide guidance for clinical treatment.Records of elderly patients with FIF who were treated with PFNA in our hospital from September 2014 to May 2017 were reviewed. They were divided into transfused and nontransfused groups. The Student t test, Chi-squared test, and Fisher exact test were used in univariate analysis of 11 variables. Multivariate logistic regression analysis was performed to analyze the possible risk factors associated with postoperative blood transfusion after the application of PFNA in elderly patients with FIF. Correlations were sought using the Spearman rank correlation analysis.The univariate analysis showed that age, sex, type of fracture, admission hemoglobin (Hb), admission albumin, and intraoperative blood loss were significantly associated with perioperative blood transfusion (P = .000, .019, .000, .000, .000, and .007, respectively). The multivariate logistic regression analysis demonstrated that age (P = .019, odds ratio [OR] = 1.062), type of fracture (P = .001, OR = 4.486), and admission Hb (P = .000, OR = 0.883) were independent risk factors of postoperative blood transfusion. We found a significant positive correlation between perioperative blood transfusion and age (r = 0.264, P = .000) and type of fracture (r = 0.409, P = .000), but a negative correlation between perioperative blood transfusion and admission Hb (r = -0.641, P = .000).The main factors affecting perioperative blood transfusion are age, fracture type, and admission Hb. These results indicate that, in high-risk patients who are older in age, more unstable fractures, and lower admission Hb, monitoring Hb concentrations during the perioperative period is important to correct severe anemia in a timely manner and avoid exacerbating existing underlying diseases and inducing severe complications.

Abstract
BACKGROUND There are significant variations in transfusion rates among institutions performing total joint arthroplasty. We previously demonstrated that implementation of an educational program to increase awareness of the American Association of Blood Banks' transfusion guidelines led to an immediate decrease in transfusion rates at our facilities. It remained unclear how this initiative would endure over time. We report the long-term success and sustainability of this quality program. METHODS We reviewed the Michigan Arthroplasty Collaborative Quality Initiative data from 2012 through 2017 of all patients undergoing primary hip and knee arthroplasty at our institutions for preoperative and postoperative hemoglobin level, transfusion status, and number of units transfused and transfusions outside of protocol to identify changes surrounding our blood transfusion educational initiative. We calculated the transfusions prevented and cost implications over the course of the study. RESULTS We identified 6645 primary hip and knee arthroplasty patients. There was a significant decrease in transfusion rate and overall transfusions in each group when compared to pre-education values. Subgroup analysis of TKA and THA independently showed significant decreases in both transfusion rate and overall transfusions. Over the final 3 years of the study, only 2 patients were transfused outside of the American Association of Blood Banks protocol. We estimate prevention of 519 transfusions over the study period. CONCLUSION Application of this quality initiative was an effective means of identifying opportunities for quality improvement. The program was easily initiated, had significant early impact, and has been shown to be sustainable.

Cost-effectiveness comparison of routine transfusion with restrictive and liberal transfusion strategies for surgical patients in China. Vox Sang 2019; 114:721-739.

Abstract
BACKGROUND AND OBJECTIVES A health industry standard recommending restrictive transfusion is to be in effect in China in April 2019. We aim to explore its potential economic and clinical impacts among surgical patients. MATERIALS AND METHODS A decision tree model was applied to compare cost-effectiveness of current routine transfusion in China, a restrictive (transfusion at Hb < 8 g/dl or ischaemic symptoms) and a liberal (transfusion at Hb < 10 g/dl) strategy. Parameters were estimated from empirical data of 25 227 surgical inpatients aged ≥30 years in a multicenter study and supplemented by meta-analysis when necessary. Results are shown for cardio-cerebral-vascular (CCV) surgery and non-CCV (orthopaedics, general, thoracic) surgery separately. RESULTS Per 10 000 patients in routine, restrictive, liberal transfusion scenarios, total spending (transfusion and length of stay related) was 7·67, 7·58 and 9·39 million CNY (1 CNY × 0.157 = 1 US dollar) for CCV surgery and 6·35, 6·70 and 8·09 million CNY for non-CCV surgery; infectious and severe complications numbered 354, 290, and 290 (CCV) and 315, 286, and 330 (non-CCV), respectively. Acceptability curves showed high probabilities for restrictive strategy to be cost-effective across a wide range of willingness-to-pay values. Such findings were mostly consistent in sensitivity and subgroup analyses except for patients with cardiac problems. CONCLUSION We showed strong rationale, succeeding previous findings only in cardiac or joint procedures, to comply with the new standard as restrictive transfusion has high potential to save blood, secure safety, and is cost-effective for a wide spectrum of surgical patients. Experiences should be further summarized to pave the way towards individualized transfusion.

Abstract
WHAT WE ALREADY KNOW ABOUT THIS TOPIC WHAT THIS ARTICLE TELLS US THAT IS NEW: BACKGROUND:: Although randomized trials show that patients do well when given less blood, there remains a persistent impression that orthopedic surgery patients require a higher hemoglobin transfusion threshold than other patient populations (8 g/dl vs. 7 g/dl). The authors tested the hypothesis in orthopedic patients that implementation of a patient blood management program encouraging a hemoglobin threshold less than 7 g/dl results in decreased blood use with no change in clinical outcomes. METHODS After launching a multifaceted patient blood management program, the authors retrospectively evaluated all adult orthopedic patients, comparing transfusion practices and clinical outcomes in the pre- and post-blood management cohorts. Risk adjustment accounted for age, sex, surgical procedure, and case mix index. RESULTS After patient blood management implementation, the mean hemoglobin threshold decreased from 7.8 ± 1.0 g/dl to 6.8 ± 1.0 g/dl (P < 0.0001). Erythrocyte use decreased by 32.5% (from 338 to 228 erythrocyte units per 1,000 patients; P = 0.0007). Clinical outcomes improved, with decreased morbidity (from 1.3% to 0.54%; P = 0.01), composite morbidity or mortality (from 1.5% to 0.75%; P = 0.035), and 30-day readmissions (from 9.0% to 5.8%; P = 0.0002). Improved outcomes were primarily recognized in patients 65 yr of age and older. After risk adjustment, patient blood management was independently associated with decreased composite morbidity or mortality (odds ratio, 0.44; 95% CI, 0.22 to 0.86; P = 0.016). CONCLUSIONS In a retrospective study, patient blood management was associated with reduced blood use with similar or improved clinical outcomes in orthopedic surgery. A hemoglobin threshold of 7 g/dl appears to be safe for many orthopedic patients.

Abstract
BACKGROUND Most clinical guidelines recommend a restrictive red-blood-cell (RBC) transfusion threshold. However, indications for transfusion in patients with a hip fracture have not been definitively evaluated or remain controversial. We compared the pros and cons of restrictive versus liberal transfusion strategies in patients undergoing hip fracture surgery. METHODS Electronic databases were searched to identify randomized controlled trials (RCTs) and retrospective cohort studies (RCSs) to investigate the effects of a restrictive strategy versus its liberal counterpart in patients undergoing hip fracture surgery. The main clinical outcomes included delirium, mortality, infections, cardiogenic complications, thromboembolic events, cerebrovascular accidents, and length of hospital stay. The meta-analysis program of the Cochrane Collaboration (RevMan version 5.3.0) was used for data analysis. Statistical heterogeneity was assessed by both Cochran chi-squared test (Q test) and I test. Both Begg and Egger tests were used to assess potential publication bias. RESULTS We identified 7 eligible RCTs and 2 eligible RCSs, involving 3,575 patients in total. In patients undergoing hip fracture surgery, we found no differences in frequency of delirium, mortality, the incidence rates of all infections, pneumonia, wound infection, all cardiovascular events, congestive heart failure, thromboembolic events or length of hospital stay between restrictive and liberal thresholds for RBC transfusion (P >.05). However, we found that the use of restrictive transfusion thresholds is associated with higher rates of acute coronary syndrome (P <.05) while liberal transfusion thresholds increase the risk of cerebrovascular accidents (P <.05). CONCLUSION In patients undergoing hip fracture surgery, clinicians should evaluate the patient's condition in detail and adopt different transfusion strategies according to the patient's specific situation rather than merely using a certain transfusion strategy.

Abstract
In patients with anemia, transfusion of red blood cells (RBCs) can save lives and improve quality of life. The choice to transfuse should be cautiously made owing to risks of transfusion, economic costs, and limitations on the blood supply. Until the 1980s, the decision for RBC transfusion was guided by Hb threshold, with the aim of maintaining the patient's blood Hb level over 100 grams per liter. Since then, multiple randomized controlled trials and key systematic reviews have provided evidence-based guidelines as to appropriate transfusion thresholds in a number of clinical settings. Here, we aimed to address the outcome of defining different anemia criteria in specific clinical populations exclusively on the basis of the need for RBC transfusion based on Hb concentration. We focused on the patient populations, where there were the most available data on differing transfusion thresholds, which looked at transfusing to a higher or liberal transfusion threshold in comparison with a lower or restrictive transfusion threshold. These included patients in intensive care with or without septic shock, hip fracture surgery, cardiovascular surgery, and upper gastrointestinal bleeding, the pediatric population, and also those with malaria, by reviewing key randomized controlled trials and systematic reviews. Twenty-four randomized controlled studies and 12 systematic reviews have been included, and these are discussed below.

Abstract
Supplemental Digital Content is available in the text. Objective: To address the significant uncertainty as to whether transfusion thresholds for critical care versus surgical patients should differ. Design: Meta-analysis of randomized controlled trials. Setting: Medline, EMBASE, and Cochrane Library searches were performed up to 15 June 2016. Patients: Trials had to enroll adult surgical or critically ill patients for inclusion. Interventions: Studies had to compare a liberal versus restrictive threshold for the transfusion of allogeneic packed RBCs. Measurements and Main Results: The primary outcome was 30-day all-cause mortality, sub-grouped by surgical and critical care patients. Secondary outcomes included myocardial infarction, stroke, renal failure, allogeneic blood exposure, and length of stay. Odds ratios and weighted mean differences were calculated using random effects meta-analysis. To assess whether subgroups were significantly different, tests for subgroup interaction were used. Subgroup analysis by trials enrolling critically ill versus surgical patients was performed. Twenty-seven randomized controlled trials (10,797 patients) were included. In critical care patients, restrictive transfusion resulted in significantly reduced 30-day mortality compared with liberal transfusion (odds ratio, 0.82; 95% CI, 0.70–0.97). In surgical patients, a restrictive transfusion strategy led to the opposite direction of effect for mortality (odds ratio, 1.31; 95% CI, 0.94–1.82). The subgroup interaction test was significant (p = 0.04), suggesting that the effect of restrictive transfusion on mortality is statistically different for critical care (decreased risk) versus surgical patients (potentially increased risk or no difference). Regarding secondary outcomes, for critically ill patients, a restrictive strategy resulted in reduced risk of stroke/transient ischemic attack, packed RBC exposure, transfusion reactions, and hospital length of stay. In surgical patients, restrictive transfusion resulted in reduced packed RBC exposure. Conclusions: The safety of restrictive transfusion strategies likely differs for critically ill patients versus perioperative patients. Further trials investigating transfusion strategies in the perioperative setting are necessary.

Abstract
INTRODUCTION To examine prognostic factors that influence complications after hip fracture surgery. To summarize proposed underlying mechanisms for their influence. METHODS We reported according to the Preferred Reporting Items for Systematic Review and Meta-Analysis Scoping Review extension. We searched MEDLINE, Embase, CINAHL, AgeLine, Cochrane Library, and reference lists of retrieved studies for studies of prognostic factor/s of postoperative in-hospital medical complication/s among patients 50 years and older treated surgically for non-pathological closed hip fracture, published in English on January 2008-January 2018. We excluded studies of surgery type or in-hospital medications. Screening was duplicated by two independent reviewers. One reviewer completed the extraction with accuracy checks by the second reviewer. We summarized the extent, nature, and proposed underlying mechanisms for the prognostic factors of complications narratively and in a dependency graph. RESULTS We identified 44 prognostic factors of in-hospital complications after hip fracture surgery from 56 studies. Of these, we identified 7 patient factors-dehydration, anemia, hypotension, heart rate variability, pressure risk, nutrition, and indwelling catheter use; and 7 process factors-time to surgery, anesthetic type, transfusion strategy, orthopedic versus geriatric/co-managed care, multidisciplinary care pathway, and potentially modifiable during index hospitalization. We identified underlying mechanisms for 15 of 44 factors. The reported association between 12 prognostic factors and complications was inconsistent across studies. CONCLUSIONS Most factors were reported by one study with no proposed underlying mechanism for their influence. Where reported by more than one study, there was inconsistency in reported associations and the conceptualization of complications differed, limiting comparison across studies. It is therefore not possible to be certain whether intervening on these factors would reduce the rate of complications after hip fracture surgery.

Results of an anaemia treatment protocol complementary to blood transfusion in elderly patients with hip fracture. Rev Esp Geriatr Gerontol 2019; 54:272-279. [PMID: 31266660 DOI: 10.1016/j.regg.2019.05.003] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2018] [Revised: 03/21/2019] [Accepted: 05/03/2019] [Indexed: 01/15/2023]
Abstract
BACKGROUND Anaemia is a very common condition in elderly patients with hip fracture. The side effects of blood transfusions are well known, and further research on potential alternative therapies is needed. OBJECTIVES AND DESIGN A non-controlled descriptive study, conducted on 138 patients admitted for hip fracture, aimed at analysing the effects of an anaemia treatment protocol adjunctive to transfusion, based on the use of supra-physiological doses of intravenous iron and erythropoietin (IS/EPOS). The variables collected were, medical history, physical and cognitive status prior to fracture, as well as the need of blood products, medical complications during admission and their functional outcome at three and six months after the fracture were evaluated. Transfusion rates were compared with a historical control group when the only treatment for acute anaemia was transfusion (2011). RESULTS Almost half (63, 48%) of the patients received blood transfusion, with (91,70%) IS/EPOD. Intravenous iron did not reduce the percentage of transfused patients (56% vs. 44%), but it did reduce the number of blood units required (0.7 units less in IS/EPO group). Patients who required transfusion had a longer hospital stay, (1.7 days; 13.2 vs. 11.5; p<0.005). Patients who received IS had better functional recovery assessed with Barthel index and the Functional Ambulation Categories (FAC scale) at 3 and 6 months after the fracture. Patients with malnutrition or subtrochanteric fracture needed more tabletransfusions (p<0.005). Functional recovery at 3 and 6 months after fracture was better in patients who received intravenous iron. Neither blood transfusions nor intravenous iron were associated with infectious complications or increased mortality. The patient series of this study was compared with a group of patients with hip fracture and similar characteristics seen in 2011, before intravenous iron was available, revealing a 17% reduction in blood transfusion needs (p<0.005). CONCLUSION The use of intravenous iron in elderly patients with hip fracture may help to reduce the number of blood units needed for the treatment of anaemia, although a causal relationship cannot be established due to not having a control group. Transfusions were associated with longer hospital stay in elderly patients with hip fracture.

Topical tranexamic acid in elderly patients with femoral neck fractures treated with hemiarthroplasty: efficacy and safety? - a case-control study. BMC Musculoskelet Disord 2019; 20:228. [PMID: 31101040 PMCID: PMC6525434 DOI: 10.1186/s12891-019-2615-z] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2019] [Accepted: 05/06/2019] [Indexed: 11/10/2022] Open
Abstract
Background Perioperative blood management is an important issue in the treatment of elderly patients at an increased risk of postoperative complications. Accordingly, tranexamic acid (TXA) is widely administered to reduce blood loss and transfusion requirements. In this case-control study, the effect of topical TXA on the outcomes of elderly patients with femoral neck fractures after hemiarthroplasty was evaluated. Methods This study enrolled elderly patients (age ≥ 70 years) who underwent cementless bipolar hemiarthroplasty for femoral neck fractures between January 2015 and January 2017. The study group comprised 72 patients who received TXA via topical administration during surgery. After propensity matching, the control group comprised 72 patients who did not receive topical TXA. The perioperative and postoperative parameters of the two groups were compared. Results The estimated blood loss, vacuum tube drainage, and total transfusion volume were significantly lower in the study group than the control (p = 0.024, 0.003, and 0.019, respectively). Despite a lack of significant intergroup differences in the lengths of ICU and hospital stays; rates of ICU admission, venous thromboembolism, delirium, and readmission; and rates of in-hospital and 1-year mortality, the incidence of postoperative medical complications was significantly lower in the study group (p = 0.003). Conclusion Topical TXA administration appears to be a simple and effective option for reducing blood loss, transfusion requirements, and medical complications after hemiarthroplasty in elderly patients with femoral neck fractures.

Abstract
Evidence-based patient blood management guidelines commonly recommend restrictive hemoglobin thresholds of 70 to 80 g/L for asymptomatic adults. However, most transfusion trials have enrolled adults across a broad age span, with few exclusive to older adults. Our recent meta-analysis of transfusion trials that focused on older adults paradoxically found lower mortality and fewer cardiac complications when these patients were managed using higher hemoglobin thresholds. We postulate that declining cardiac output with age contributes to deteriorating oxygen delivery capacity which impacts anemia-associated outcomes in older adults and propose a model to explain this age-related difference. We reviewed evidence concerning the pathophysiology of aging to explore the disparity in transfusion trial outcomes related to hemoglobin thresholds in different age groups. The literature was searched for normative cardiac output values at different ages in healthy adults. Using normative peak cardiac output data, we modeled oxygen delivery capacity in young, middle-aged, and older adults at a range of hemoglobin levels. Cardiovascular and pulmonary systems are impacted by age-related pathophysiological changes. Diminishing peak cardiac output associated with aging reduces the maximal oxygen delivery achievable under metabolic stress. Hence, at low hemoglobin levels, older adults are more susceptible to tissue hypoxia than younger adults. Our model predicts that an older adult with a hemoglobin of 100 g/L has a similar peak oxygen delivery capacity to a young adult with a hemoglobin of 70 g/L. Age-related pathophysiological changes provide some explanation as to why older adults have a lower tolerance for anemia than younger adults. This indicates the need for patient blood management hemoglobin thresholds specific to older as distinct from younger adults. The primary application of this model is in the consideration of patients rehabilitating to life outside hospital. It is important to note that pathophysiological changes associated with critical illness and major surgery are more complex than can be described in a simple model based on cardiac output and hemoglobin concentration. However, our review of oxygen transport and delivery in health and disease states allows the model to be considered in the context of treatment decisions for anemic adults in a range of hospital and community settings.

Abstract
Background Considering the functional role of red blood cells (RBC) in maintaining oxygen supply to tissues, RBC transfusion can be a life-saving intervention in situations of severe bleeding or anemia. RBC transfusion is often inevitable to address intraoperative massive bleeding; it is a key component in safe perioperative patient management. Unlike general medical resources, packed RBCs (pRBCs) have limited availability because their supply relies entirely on voluntary donations. Additionally, excessive utilization of pRBCs may aggravate prognosis or increase the risk of developing infectious diseases. Appropriate perioperative RBC transfusion is, therefore, crucial for the management of patient safety and medical resource conservation. These concerns motivated us to develop the present clinical practice guideline for evidence-based efficient and safe perioperative RBC transfusion management considering the current clinical landscape. Methods This guideline was obtained after the revision and refinement of exemplary clinical practice guidelines developed in advanced countries. This was followed by rigorous evidence-based reassessment considering the healthcare environment of the country. Results This guideline covers all important aspects of perioperative RBC transfusion, such as preoperative anemia management, appropriate RBC storage period, and leukoreduction (removal of white blood cells using filters), reversal of perioperative bleeding tendency, strategies for perioperative RBC transfusion, appropriate blood management protocols, efforts to reduce blood transfusion requirements, and patient monitoring during a perioperative transfusion. Conclusions This guideline will aid decisions related to RBC transfusion in healthcare settings and minimize patient risk associated with unnecessary pRBC transfusion.

Abstract
BACKGROUND With over 230 million surgical procedures performed annually worldwide, better application of evidence in anesthesia and perioperative medicine may reduce widespread variation in clinical practice and improve patient care. However, a comprehensive summary of the complete available evidence has yet to be conducted. This scoping review aims to map the existing literature investigating perioperative anesthesia interventions and their potential impact on patient mortality, to inform future knowledge translation and ultimately improve perioperative clinical practice. METHODS Searches were conducted in MEDLINE, EMBASE, CINAHL, and the Cochrane Library databases from inception to March 2015. Study inclusion criteria were adult patients, surgical procedures requiring anesthesia, perioperative intervention conducted/organized by a professional with training in anesthesia, randomized controlled trials (RCTs), and patient mortality as an outcome. Studies were screened for inclusion, and data was extracted in duplicate by pairs of independent reviewers. Data were extracted, tabulated, and reported thematically. RESULTS Among the 10,505 publications identified, 369 RCTs (n = 147,326 patients) met the eligibility criteria. While 15 intervention themes were identified, only 7 themes (39 studies) had a significant impact on mortality: pharmacotherapy (n = 23), nutritional (n = 3), transfusion (n = 4), ventilation (n = 5), glucose control (n = 1), medical device (n = 2), and dialysis (n = 1). CONCLUSIONS By mapping intervention themes, this scoping review has identified areas requiring further systematic investigation given their potential value for reducing patient mortality as well as areas where continued investment may not be cost-effective given limited evidence for improving survival. This is a key starting point for future knowledge translation to optimize anesthesia practice.

Abstract
PURPOSE To define risk factors for rehospitalization following fragility hip fractures and to create a predictive model. METHODS A retrospective cohort study of patients 65 years and older, who were treated operatively following fragility hip fractures between 01.2011 and 06.2016. Patients were allocated into two study groups based on the occurrence of recurrent hospitalizations in the year following surgery. Demographic information, comorbidities, and in-hospital characteristics were collected, as was information regarding 1-year readmissions. Multivariate analysis of factors predictive of rehospitalizations was performed, followed by a logistic regression using all predictors with p < 0.05. A stepwise backwards elimination method was used to create the predictive model. RESULTS Eight hundred and fifty-one patients were included; 369 (43.4%) had recurrent hospitalizations within the first post-operative year. Patients who were rehospitalized were more likely to be males, to use a walking aid and to live dependently. They had a higher age-adjusted Charlson's comorbidity index (ACCI) score, a higher perveance of atrial fibrillation, lower hemoglobin, worse renal function, less platelets, and longer time to surgery. Prevalence of in-hospital complications was similar. Six variables were found to independently influence the chance for readmissions: male gender, the use of a walking aid, higher ACCI score, lower hemoglobin, atrial fibrillation, and a longer surgical delay. Only the first four were found to be adequate predictors and were added to the prediction formula. CONCLUSION High 1-year readmission rates are seen following discharge in patients with fragility hip fractures. Addressing risk factors might aid to better rehabilitate patients and reduce morbidity.

Abstract
BACKGROUND Several new trials evaluating transfusion strategies in patients with cardiovascular disease have recently been published, increasing the number of enrolled patients by over 30%. The objective was to evaluate transfusion thresholds in patients with cardiovascular disease. METHODS We conducted an updated systematic review of randomized trials that compared patients assigned to maintain a lower (restrictive transfusion strategy) or higher (liberal transfusion strategy) hemoglobin concentration. We focused on new trial data in patients with cardiovascular disease. The primary outcome was 30-day mortality. Specific subgroups were patients undergoing cardiac surgery and with acute myocardial infarction. RESULTS A total of 37 trials that enrolled 19,049 patients were appraised. In cardiac surgery, mortality at 30days was comparable between groups (risk ratio 0.99; 95% confidence interval 0.74-1.33). In 2 small trials (n=154) in patients with myocardial infarction, the point estimate for the mortality risk ratio was 3.88 (95% CI, 0.83-18.13) favoring the liberal strategy. Overall, from 26 trials enrolling 15,681 patients, 30-day mortality was not different between restrictive and liberal transfusion strategies (risk ratio 1.0, 95% CI, 0.86-1.16). Overall and in the cardiovascular disease subgroup, there were no significant differences observed across a range of secondary outcomes. CONCLUSIONS New trials in patients undergoing cardiac surgery establish that a restrictive transfusion strategy of 7 to 8g/dL is safe and decreased red cell use by 24%. Further research is needed to define the optimal transfusion threshold in patients with acute myocardial infarction.

Abstract
BACKGROUND Our primary goal was to audit the incidence of erythrocyte blood transfusion (EBT) after hip fracture surgery and study the effects on perioperative complications and early and late mortality. METHODS In a retrospective cohort study all patients 65 years old and above treated operatively for an acute hip fracture were included over a 48-month period with a 2-year follow-up period. Postoperative hemoglobin levels were used to investigate at what threshold EBT was used. The relation between EBT and perioperative complications and survival was analyzed with multivariate regression analysis. A propensity score for predicting the chance of receiving an EBT was calculated and used to differentiate between transfusion being a risk factor for mortality and other related confounding risk factors. Mortality was subdivided as in-hospital, 30-day, 1-year and 2-year mortality. RESULTS Of the 388 included patients, 41% received a blood transfusion. The postoperative hemoglobin level was the strongest predictor for EBT. Patients who received EBT had a significant longer hospital stay and more postoperative cardiac complications, even after adjustment for confounders. Multivariate analysis for mortality showed that EBT was a significant risk factor for early as well as late mortality, but after adding the propensity score, EBT was no longer associated with increased mortality. CONCLUSION There was no effect of EBT on mortality after correction with propensity scoring for predictors of EBT. Transfusion in patients treated operatively for hip fracture should be evenly matched with their cardiovascular risk during the perioperative phase.

Abstract
BACKGROUND Current guidelines recommend restrictive criteria for red blood-cell transfusion in most clinical settings. However, patients undergoing orthopaedic surgery may require distinct transfusion criteria since benefits and potential harm often vary considerably based on patient characteristics and surgical procedures. We aimed to assess the efficacy and safety of restrictive transfusion in patients undergoing orthopaedic surgery, especially in important subgroups. METHODS Electronic databases were searched to identify randomized controlled trials investigating restrictive (mostly a hemoglobin level of 8.0 g/dL or symptomatic anemia) versus liberal (mostly a hemoglobin level of 10.0 g/dL) transfusion in patients undergoing orthopaedic surgery. For the primary outcome of cardiovascular events, we performed random-effects meta-analyses to synthesize the evidence and to assess the effects in different subgroups according to patient characteristics (with versus without preexisting cardiovascular disease) and surgical procedures (hip fracture surgery versus elective arthroplasty). RESULTS Ten trials involving 3,968 participants who underwent hip or knee surgery were included. Mean participant age ranged from 68.7 to 86.9 years. Compared with liberal transfusion, restrictive transfusion increased the risk of cardiovascular events (8 trials; 3,618 participants; relative risk [RR], 1.51; 95% confidence interval [CI], 1.16 to 1.98; p = 0.003; with no heterogeneity across all trials), irrespective of preexisting cardiovascular disease (pinteraction = 0.63). In a subgroup analysis, the increase was observed in patients undergoing hip fracture surgery (RR, 1.51; 95% CI, 1.08 to 2.10; p = 0.02), but did not reach significance in those undergoing elective arthroplasty (RR, 1.53; 95% CI, 0.96 to 2.44; p = 0.07). To minimize the bias caused by variations in transfusion threshold, we conducted an analysis that only included trials using 8.0 g/dL hemoglobin or symptomatic anemia as the threshold for restrictive transfusion and obtained identical results (6 trials; 2,872 participants; RR, 1.51; 95% CI, 1.09 to 2.08; p = 0.01; I = 0%). The 2 arms did not differ with respect to the rates of all infections, 30-day mortality, thromboembolic events, wound infection, pulmonary infection (mainly pneumonia), and cerebrovascular accidents (mainly stroke). CONCLUSIONS In patients undergoing orthopaedic surgery, when compared with liberal transfusion, restrictive transfusion increases the risk of cardiovascular events irrespective of preexisting cardiovascular disease. Importantly, the increased risk was observed in patients undergoing hip fracture surgery but did not reach significance in those undergoing elective arthroplasty.

Abstract
Background Benefits and risks of liberal and restrictive transfusion regimens are under on-going controversial discussion. This systematic review aimed at assessing both regimens in terms of pre-defined outcomes with special focus on patients undergoing major orthopaedic surgery. Methods We performed a literature search for mortality, morbidity and related outcomes following peri-operative blood transfusion in patients with major orthopaedic surgery in electronic databases. Combined outcome measure estimates were calculated within the scope of meta-analyses including randomised clinical trials comparing restrictive versus liberal blood transfusion regimens (e.g. MH risk ratio, Peto odds ratio). Results A total of 880 publications were identified 15 of which were finally included (8 randomised clinical trials (RCTs) with 3,693 patients and 6 observational studies with 4,244,112 patients). Regarding RCTs, no significant differences were detected between the transfusion regimes for all primary outcomes (30-day mortality, thromboembolic events, stroke/transitory ischaemic attack, myocardial infarction, wound infection and pneumonia) and a secondary outcome (length of hospital stay), whereas there was a significantly reduced risk of receiving at least one red blood concentrate under a restrictive regimen. Conclusion The results of this systematic review do not suggest an increased risk associated with either a restrictive or a liberal transfusion regimen in patients undergoing major orthopaedic surgery.

A model-based cost-effectiveness analysis of Patient Blood Management. BLOOD TRANSFUSION = TRASFUSIONE DEL SANGUE 2018.

Abstract
BACKGROUND Patient blood management (PBM) is a multidisciplinary concept focused on the management of anaemia, minimisation of iatrogenic blood loss and rational use of allogeneic blood products. The aims of this study were: (i) to analyse post-operative outcome in patients with liberal vs restrictive exposure to allogeneic blood products and (ii) to evaluate the cost-effectiveness of PBM in patients undergoing surgery. MATERIALS AND METHODS A systematic literature review and meta-analysis were performed to compare post-operative complications in predominantly non-transfused patients (restrictive transfusion group) and patients who received one to three units of red blood cells (liberal transfusion group). Outcome measures included sepsis with/without pneumonia, acute renal failure, acute myocardial infarction and acute stroke. In a second step, a health economic model was developed to calculate cost-effectiveness of PBM (PBM-arm vs control-arm) for simulated cohorts of 10,000 cardiac and non-cardiac surgical patients based on the results of the meta-analysis and costs. RESULTS Out of 478 search results, 22 studies were analysed in the meta-analysis. The pooled relative risk of any complication in the restrictive transfusion group was 0.43 for non-cardiac and 0.34 for cardiac surgical patients. In the simulation model, PBM was related to reduced complications (1,768 vs 1,245) and complication-related deaths (411 vs 304) compared to standard care. PBM-related costs of therapy exceeded costs of the control arm by € 150 per patient. However, total costs, including hospitalisation, were higher in the control-arm for both non-cardiac (€ 2,885.11) and cardiac surgery patients (€ 1,760.69). The incremental cost-effectiveness ratio including hospitalisation showed savings of € 30,458 (non-cardiac and cardiac surgery patients) for preventing one complication and € 128,023 (non-cardiac and cardiac surgery patients) for prevention of one complication-related death in the PBM-arm. DISCUSSION Our results indicate that PBM may be associated with fewer adverse clinical outcomes compared to control management and may, thereby, be cost-effective.

Abstract
OBJECTIVES Hemolysis is one of the most prominent changes that occur during the liquid storage of RBCs in additive solution (AS), but most studies have measured hemolysis only on day 42. METHODS Prestorage leukoreduced RBCs in AS-1 and AS-3 were studied, one group on day 42 and a second group between day 0 and day 40. Each product was sampled for direct measurement of supernatant hemoglobin and hematocrit. RESULTS Ninety day 42 and 218 day 7 to day 39 RBCs showed a mean ± SD supernatant hemoglobin of 75 ± 100 vs 25.5 ± 16 mg/dL respectively (P < .01). Supernatant hemoglobin correlated weakly with storage age (r = 0.2, P < .01) but more strongly with hematocrit (r = 0.4, P < .01). CONCLUSIONS There are minimal differences in supernatant hemoglobin until the final days of liquid storage when some high hematocrit RBCs show excessive hemolysis.
