BMC Cardiovasc Disord 2023; 23:598. [PMID: 38062386 PMCID: PMC10704751 DOI: 10.1186/s12872-023-03647-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2023] [Accepted: 11/29/2023] [Indexed: 12/18/2023] Open
Abstract
BACKGROUND Extracorporeal circulation auxiliary to open heart surgery is a common procedure used to treat heart diseases. However, the optimal transfusion strategy for patients undergoing this surgery remains a subject of debate. This study aims to investigate the association between hemoglobin levels and clinical outcomes in patients undergoing extracorporeal circulation auxiliary to open heart surgery, with the ultimate goal of improving surgical success rates and enhancing patients' quality of life. METHODS A retrospective analysis was conducted on data from the Medical Information Mart for Intensive Care IV 2.2 (MIMIC-IV 2.2) database, including 4144 patients. The patients were categorized into five groups based on their minimum hemoglobin levels during hospitalization. Baseline characteristics, clinical scores, laboratory results, and clinical outcome data were collected. Statistical analyses utilized descriptive statistics, ANOVA or Kruskal-Wallis tests, Kaplan-Meier method, and Log-rank test. RESULTS The results revealed a significant correlation between hemoglobin levels and in-hospital mortality, as well as mortality rates at 30 days, 60 days, and 180 days (p < 0.001). Patients with lower hemoglobin levels exhibited higher mortality rates. However, once hemoglobin levels exceeded 7g/dL, no significant difference in mortality rates was observed (p = 0.557). Additionally, lower hemoglobin levels were associated with prolonged hospital stay, ICU admission time, and mechanical ventilation time (p < 0.001). Furthermore, hemoglobin levels were significantly correlated with complication risk, norepinephrine dosage, and red blood cell transfusion volume (p < 0.001). However, there was no significant difference among the groups in terms of major complications, specifically sepsis (p > 0.05). CONCLUSION The study highlights the importance of managing hemoglobin levels in patients undergoing heart surgery with extracorporeal circulation. Hemoglobin levels can serve as valuable indicators for predicting clinical outcomes and guiding treatment decisions. Physicians should carefully consider hemoglobin levels to optimize transfusion strategies and improve postoperative patient outcomes. Further research and intervention studies are warranted to validate and implement these findings in clinical practice.

Haase DR, Haase LR, Moon TJ, Dallman J, Vance D, Benedick A, Ochenjele G, Napora JK, Wise BT. Perioperative allogenic blood transfusions are associated with increased fracture related infection rates, but not nonunion in operatively treated distal femur fractures. Injury 2023:S0020-1383(23)00383-2. [PMID: 37188588 DOI: 10.1016/j.injury.2023.04.041] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/03/2022] [Revised: 04/11/2023] [Accepted: 04/23/2023] [Indexed: 05/17/2023]
Abstract
INTRODUCTION Distal femur fractures are common injuries that remain difficult for orthopedic surgeons to treat. High complication rates, including nonunion rates as high as 24% and infection rates of 8%, can lead to increased morbidity for these patients. Allogenic blood transfusions have previously been identified as risk factors for infection in total joint arthroplasty and spinal fusion surgeries. No studies have explored the relationship between blood transfusions and fracture related infection (FRI) or nonunion in distal femur fractures. METHODS 418 patients with operatively treated distal femur fractures at two level I trauma centers were retrospectively reviewed. Patient demographics were collected including age, gender, BMI, medical comorbidities, and smoking. Injury and treatment information was also collected including open fracture, polytrauma status, implant, perioperative transfusions, FRI, and nonunion. Patients with less than three months of follow up were excluded. RESULTS 366 patients were included in final analysis. One hundred thirty-nine (38%) patients received a perioperative blood transfusion. Forty-seven (13%) nonunions and 30 (8%) FRI were identified. Allogenic blood transfusion was not associated with nonunion (13% vs 12%, P = 0.87), but was associated with FRI (15% vs 4%, P<0.001). Binary logistic regression analysis identified a dose dependent relationship between number of perioperative blood transfusions and FRI: total transfusion ≥2 U PRBC RR= 3.47(1.29, 8.10, P = 0.02), ≥3 RR= 6.99 (3.01, 12.40, P<0.001), and ≥4 RR= 8.94 (4.03, 14.42, P<0.001). DISCUSSION In patients undergoing operative treatment of distal femur fractures, perioperative blood transfusions are associated with increased risk of fracture related infection, but not the development of a nonunion. This risk association increases in a dose-dependent relationship with increasing total blood transfusions received.

Cureus 2023; 15:e38825. [PMID: 37303443 PMCID: PMC10251790 DOI: 10.7759/cureus.38825] [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] [Accepted: 05/09/2023] [Indexed: 06/13/2023] Open
Abstract
Introduction The current reported mortality rate for elderly neck of femur fractures (eNOFF) is relatively high in the UK. eNOFF patients commonly suffer from associated cardiovascular co-morbidities and tend to have fragile physiological states and poor physiological reserves. Although some studies have shown a potential link between blood transfusion and mortality in eNOFF patients, there is no general consensus on this matter. Therefore, our study aims to explore the possible association between blood transfusion and length of hospital stay (LOHS) as well as short- and long-term mortality rates in eNOFF patients by reviewing the practice of blood transfusion. Methods This retrospective study was conducted at Wrexham Maelor Hospital, which is part of the Betsi Cadwaladr University Health Board (BCUHB), Wales. The study included patients who were 65 years of age or older and presented with neck of femur fractures. Only patients who required surgical intervention were included, and those managed non-operatively were excluded from the study. The statistical analysis was performed using IBM SPSS Statistics for Windows, Version 25.0 (IBM Corp., Armonk, New York, United States). Furthermore, unpaired t-tests and log-rank (Mantel-Cox) tests were performed to compare the groups that received blood transfusions. Results During the study period, a total of 501 eNOFF patients were included in the primary cohort of the study, with a mean age of 81 years (ranging from 65 to 102). The majority of the patients were female (n=340). Of the 501 patients, 79 (15.8%) received a blood transfusion during their treatment. Around 52.9% of the eNOFF patients were categorized as American Society of Anesthesiologists (ASA) III, but there was no statistically significant difference in the requirement of blood transfusion between patients in ASA III, II, and IV categories, as compared to ASA I. Additionally, the mean time to surgery was higher in patients who received a blood transfusion (35.8 hours), and this difference was statistically significant (p=0.035). Moreover, the average LOHS after surgery for eNOFF was longer in patients who needed peri-operative blood transfusion (22 days), and this difference in the means was statistically significant (p=0.022). At the one-year post-surgery mark, mortality was higher in the transfused group (33%), and long-term five-year mortality rates were also higher in this group (63.2%). Conclusion Peri-operative blood transfusion may confer certain benefits in the management of eNOFF ptients. However, it should not be regarded as a panacea for improving long-term outcomes. The decision to administer blood transfusion must be made on a case-by-case basis, with careful assessment of individual clinical indications, and the potential risks and benefits taken into consideration. To achieve optimal clinical outcomes, close monitoring and follow-up of eNOFF patients, both in the short-term and long-term, are essential.

Blood-Transfusion Risk Factors after Intramedullary Nailing for Extracapsular Femoral Neck Fracture in Elderly Patients. J Funct Morphol Kinesiol 2023; 8:jfmk8010027. [PMID: 36810511 PMCID: PMC9945124 DOI: 10.3390/jfmk8010027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2023] [Revised: 02/11/2023] [Accepted: 02/16/2023] [Indexed: 02/24/2023] Open
Abstract
BACKGROUND Extracapsular femoral neck fractures (eFNF) are the third most common type of fracture in traumatology. Intramedullary nailing (IMN) is one of the most frequently used ortho-pedic treatments for eFNF. Blood loss is one of the main complications of this treatment. This study aimed to identify and evaluate the perioperative risk factors that lead to blood transfusion in frail patients with eFNF who undergo IMN. METHODS From July 2020 to December 2020, 170 eFNF-affected patients who were treated with IMN were enrolled and divided into two groups according to blood transfusion: NBT (71 patients who did not need a blood transfusion), and BT (72 patients who needed blood transfusion). Gender, age, BMI, pre-operative hemoglobin levels, in-ternational normalized ratio (INR) level, number of blood units transfused, length of hospital stay, surgery duration, type of anesthesia, pre-operative ASA score, Charlson Comorbidity Index, and mortality rate were assessed. RESULTS Cohorts differed only for pre-operatively Hb and surgery time (p < 0.05). CONCLUSION Patients who have a lower preoperative Hb level and longer surgery time have a high blood-transfusion risk and should be closely followed peri-operatively.

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.

Malnutrition, poor function and comorbidities predict mortality up to one year after hip fracture: a cohort study of 2800 patients. Eur Geriatr Med 2021; 13:433-443. [PMID: 34854063 DOI: 10.1007/s41999-021-00598-x] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2021] [Accepted: 11/23/2021] [Indexed: 10/19/2022]
Abstract
PURPOSE Despite extensive research, a complete understanding of factors influencing mortality risk after hip fractures is lacking. Previous research has focused on static risk factors; however, to improve outcomes, attention should be directed towards risk factors that may be optimised. The present study aimed to investigate the association of 19 risk factors with mortality among patients with hip fracture treated according to a well-defined guideline. METHODS The study was a retrospective analysis of a large prospective patient cohort with all consecutive patients surgically treated for a hip fracture from January 2011 to December 2017 included (n = 2800). Variables were obtained from patient records and the Holstebro Hip Fracture Database comprising prospectively registered data on demographics, comorbidity, malnutrition (low Body Mass Index (BMI) or albumin) and hospital stay (including fracture and surgical data, biochemistry, mobilisation and discharge). Outcomes were 30-day and one-year mortality. RESULTS Patients were predominantly female (66%); median age 81.6 years. Overall mortality was 9% at 30 days and 24% at one year. Age ≥ 75 years, male gender, nursing home residence, cognitive impairment, American Society of Anesthesiologists (ASA) score ≥ 3, BMI < 20 kg/m2, albumin < 35 g/l, creatinine ≥ 100 µmol/l, a low New Mobility Score and no mobilisation were all associated with increased mortality at 30 days and one year. CONCLUSION In addition to non-modifiable risk factors, comorbidities (expressed as high ASA score and creatinine), malnutrition, and failure to achieve early post-operative mobilisation were associated with increased short and long-term mortality among patients with hip fracture: these are potentially modifiable. The effect of optimisation interventions warrants further research.

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.

Abstract
Objective: To identify whether the timing of surgery affects red blood cell (RBC)
transfusion requirements in the elderly with intertrochanteric
fractures. Methods: We retrospectively studied all patients undergoing surgical fixation of their
intertrochanteric fractures in our hospital between January 2009 and
December 2018 and analyzed the relationship between the timing of surgery
and RBC transfusion. Results: A total of 679 patients were included in this study. The need for RBC
transfusion was lower in the patients who underwent surgery within 12 h
after admission (timing of surgery <12 h, <12 h group) than those who
underwent surgery over 12 h after admission (timing of surgery >12 h,
>12 h group) (P = 0.046); lower in the the patients who underwent surgery
within 24 h after admission (timing of surgery <24 h, <24 h group)
than in those who underwent surgery over 24 h after admission (timing of
surgery >24 h, >24 h group) (P = 0.008), and lower in the <24 h
group compared to the patients who underwent surgery within 48 h after
admission (timing of surgery <48 h, <48 h group) (P = 0.035).
Moreover, the need for RBC transfusion was lower in the <24 h group (in
the first 24 h from admission to surgery) than in the 24-48 h group (in the
second 24 h from admission to surgery) (P = 0.016), and also lower in the
<24 h group compared to the 48-72 h group (in the third 24 h from
admission to surgery) (P = 0.047). However, there were no differences
between the <12 h group and 12-24 h group, between the <12 h group and
<24 h group, and between the 12-24 h group and <24 h group,
respectively. Conclusion: Timing of surgery within 24 h contributes to the reduction of RBC transfusion
in the elderly with intertrochanteric fractures.

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
Objetivo: La linfopenia se ha propuesto como un potencial factor asociado al riesgo de infecciones bacterianas nosocomiales (infección urinaria y neumonía), pero la magnitud y relevancia de este factor no ha sido evaluada formalmente. El objetivo de este estudio es determinar si existe asociación entre linfopenia e infecciones nosocomiales en ancianos hospitalizados en una institución de salud en Bogotá, Colombia. Métodos: Estudio de casos y controles, incluyendo personas mayores de 65 años hospitalizadas en el Hospital Universitario San Ignacio entre junio de 2016 y diciembre de 2017. Se consideraron casos aquellos con diagnóstico de infección nosocomial (neumonía, infección de vías urinarias, bacteriemia, infección de tejidos blandos) y se compararon con controles sin infección emparejados por edad y sexo. Se evaluó la asociación entre linfopenia e infección nosocomial mediante análisis bivariado y multivariado controlando por las variables de confusión. Resultados: Se incluyeron un total de 198 pacientes (99 casos y 99 controles). La prevalencia de linfopenia fue de 34.8%, sin encontrarse diferencia entre los dos grupos (p=0.88). La infección nosocomial se asoció a mayor incidencia de mortalidad (29.3 vs 10.1%, p>0.001) y mayor duración de estancia hospitalaria (Mediana 18 vs 9 días, p<0.01). Se encontró asociación entre infección nosocomial con enfermedad cardiovascular (OR = 2.87; IC 95% 1.37-6.00) y antecedente de cáncer (OR = 6.00; IC 95% 1.28-29.78), sin embargo, no hubo asociación con linfopenia (OR = 1.27; IC 95% 0.61-2.65). Conclusiones: Este estudio sugiere que no existe asociación entre linfopenia y el desarrollo de infecciones nosocomiales en pacientes ancianos.

Abstract
The number of elderly patients who frequently access health care services is increasing worldwide. While anesthesiologists are developing the expertise to care for these elderly patients, areas of concern remain. We conducted a comprehensive search of major international databases (PubMed, Embase, and Cochrane) and a Korean database (KoreaMed) to review preoperative considerations, intraoperative management, and postoperative problems when anesthetizing elderly patients. Preoperative preparation of elderly patients included functional assessment to identify preexisting cognitive impairment or cardiopulmonary reserve, depression, frailty, nutrition, polypharmacy, and anticoagulation issues. Intraoperative management included anesthetic mode and pharmacology, monitoring, intravenous fluid or transfusion management, lung-protective ventilation, and prevention of hypothermia. Postoperative checklists included perioperative analgesia, postoperative delirium and cognitive dysfunction, and other complications. A higher level of perioperative care was required for older surgical patients, as multiple chronic diseases often makes them prone to developing postoperative complications, including functional decline and loss of independence. Although the guiding evidence remains poor so far, elderly patients have to be provided optimal perioperative care through close interdisciplinary, interprofessional, and cross-sectional collaboration to minimize unwanted postoperative outcomes. Furthermore, along with adequate anesthetic care, well-planned postoperative care should begin immediately after surgery and extend until discharge.

Abstract
OBJECTIVES Assess support for the effectiveness of two separate practices, restrictive transfusion strategy and computerized physician order entry/clinical decision support (CPOE/CDS) tools, in decreasing RBC transfusions in adult surgical and nonsurgical patients. METHODS Following the Centers for Disease Control and Prevention Laboratory Medicine Best Practice (LMBP) Systematic Review (A-6) method, studies were assessed for quality and evidence of effectiveness in reducing the percentage of patients transfused and/or units of blood transfused. RESULTS Twenty-five studies on restrictive transfusion practice and seven studies on CPOE/CDS practice met LMBP inclusion criteria. The overall strength of the body of evidence of effectiveness for restrictive transfusion strategy and CPOE/CDS was rated as high. CONCLUSIONS Based on these procedures, adherence to an institutional restrictive transfusion strategy and use of CPOE/CDS tools for hemoglobin alerts or reminders of the institution's restrictive transfusion policies are effective in reducing RBC transfusion overuse.

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 The ability of acute care providers to cope with the influx of frail older patients is increasingly stressed, and changes need to be made to improve care provided to older adults. Our purpose was to conduct a scoping review to map and synthesize the literature addressing frailty in the acute care setting in order to understand how to tackle this challenge. We also aimed to highlight the current gaps in frailty research. Methods This scoping review included original research articles with acutely-ill Emergency Medical Services (EMS) or hospitalized older patients who were identified as frail by the authors. We searched Medline, CINAHL, Embase, PsycINFO, Eric, and Cochrane from January 2000 to September 2015. Results Our database search initially resulted in 8658 articles and 617 were eligible. In 67% of the articles the authors identified their participants as frail but did not report on how they measured frailty. Among the 204 articles that did measure frailty, the most common disciplines were geriatrics (14%), emergency department (14%), and general medicine (11%). In total, 89 measures were used. This included 13 established tools, used in 51% of the articles, and 35 non-frailty tools, used in 24% of the articles. The most commonly used tools were the Clinical Frailty Scale, the Frailty Index, and the Frailty Phenotype (12% each). Most often (44%) researchers used frailty tools to predict adverse health outcomes. In 74% of the cases frailty predicted the outcome examined, typically mortality and length of stay. Conclusions Most studies (83%) were conducted in non-geriatric disciplines and two thirds of the articles identified participants as frail without measuring frailty. There was great variability in tools used and more recently published studies were more likely to use established frailty tools. Overall, frailty appears to be a good predictor of adverse health outcomes. For frailty to be implemented in clinical practice frailty tools should help formulate the care plan and improve shared decision making. How this will happen has yet to be determined.

Abstract
Most packed red blood cell (PRBC) transfusion research focuses on younger patient populations (younger than 65) given the complexity of care and presence of comorbidities in older adults. The purpose of the current study was to critically examine the current evidence related to PRBC transfusion among older adults (age ≥65). PubMed, CINAHL, and Embase were searched for randomized controlled trials that evaluated blood transfusion in any manner (e.g., prevention, associated outcomes). Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, the search resulted in 10 studies focused on cardiac, orthopedic, and gastrointestinal surgery patients. SQUIRE (Standards for QUality Improvement Reporting Excellence) guidelines were used to evaluate studies for bias; the average bias score was 13.0 (SD = 3.4), indicating a low level of bias. Greatest sources of bias were methods to assess completeness/accuracy of data, details about missing data, and costs associated with the study. Interventions to prevent PRBC transfusion in older adults vary widely, and outcomes associated with PRBC transfusion in older adults require further evaluation.

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.

Abstract
BACKGROUND Frailty is an important prognostic factor for adverse outcomes and increased resource use in the growing population of older surgical patients. We identified and appraised studies that tested interventions in populations of frail surgical patients to improve perioperative outcomes. METHODS We systematically searched Cochrane, CINAHL, EMBASE and Medline to identify studies that tested interventions in populations of frail patients having surgery. All phases of study selection, data extraction, and risk of bias assessment were done in duplicate. Results were synthesized qualitatively per a prespecified protocol (CRD42016039909). RESULTS We identified 2 593 titles; 11 were included for final analysis, representing 1 668 participants in orthopedic, general, cardiac, and mixed surgical populations. Only one study was multicenter and risk of bias was moderate to high in all studies. Interventions were applied pre- and postoperatively, and included exercise therapy (n = 4), multicomponent geriatric care protocols (n = 5), and blood transfusion triggers (n = 1); no specific surgical techniques were compared. Exercise therapy, applied pre-, or post-operatively, was associated with significant improvements in functional outcomes and improved quality of life. Multicomponent protocols suffered from poor compliance and difficulties in implementation. Transfusion triggers had no significant impact on mortality or other outcomes. CONCLUSIONS Despite a growing literature that demonstrates strong independent associations between frailty and adverse outcomes, few interventions have been tested to improve the outcomes of frail surgical patients, and most available studies are at substantial risk of bias. Multicenter, low risk of bias, studies of perioperative exercise are needed, while substantial efforts are required to develop and test other interventions to improve the outcomes of frail people having surgery.

Abstract
BACKGROUND More than a million surgeries are performed annually in the United States for hip or knee arthroplasty or hip fracture stabilization. One-fifth of these patients have blood transfusions during their hospital stay. Increases in transfusion rates have caused concern about increased adverse events from unnecessary transfusions. METHODS We systematically reviewed randomized trials examining the effect of restrictive vs liberal transfusion thresholds on patients having major orthopedic surgery. Study results were meta-analyzed with a random-effects model and heterogeneity was tested with the I2 statistic. Study risk of bias was assessed using a modified Jadad scale and evidence strength was measured using the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) system. RESULTS A total of 504 published articles were screened, and 15 met inclusion criteria. The articles described 9 randomized trials, most comparing transfusion thresholds of 8 vs 10 g/dL hemoglobin. All involved hip or knee arthroplasty and/or hip fracture patients. Moderate-strength evidence suggested a reduction in need for transfusion (relative risk, 0.53; 95% confidence interval [CI], 0.39-0.71; I2 = 95%) and mean number of units transfused (-0.95 units, 95% CI, -1.48 to -0.41, I2 = 98%). There was a possible reduction in overall infections with more restrictive transfusion thresholds, although the result was not statistically significant (relative risk, 0.71; 95% CI, 0.47-1.06; I2 = 54%). Moderate-strength evidence suggested no differences in other clinical outcomes between the groups. Limitations included incomplete blinding, inconsistency, and imprecision. CONCLUSION Moderate-strength evidence suggests that restrictive transfusion practices reduce utilization of transfusions and may decrease infections without increasing adverse outcomes in major orthopedic surgery.

Abstract
The conjunction of the demographic aging and the increase in the frequency of anemia with the advancing age, mean that the number of globular concentrates delivered each year increases with a consequent heavy pressure on blood collection. The etiologies of anemia in the elderly are often multifactorial and their investigation is an indispensable step and prior to any treatment. Transfusion thresholds, particularly in the elderly, are gradually evolving and a so-called restrictive strategy is now favored. Immediate and delayed complications of transfusion are more frequent in the elderly due to vulnerability factors associated with frailty and the risk of multiple transfusions. The screening of complications related to transfusion of RBCs is essential and makes it possible to avoid their recurrence. The impact of transfusion on the quality of life of elderly patients is not obvious and is a controversial issue. In addition, transfusion of red blood cells (RBCs) is accompanied by an increase in health expenditure and an increase in morbidity and mortality, whose risks can be reduced through alternatives to transfusion. Longitudinal studies, including elderly subjects, would allow a better understanding of the issues involved in the transfusion of RBCs in this population.

Abstract
OBJECTIVES To investigate whether a liberal blood transfusion strategy [Hb levels ≥11.3 g/dL (7 mmol/L)] reduces the risk of postoperative delirium (POD) on day 10, among nursing home residents with hip fracture, compared to a restrictive transfusion strategy [Hb levels ≥9.7 g/dL (6 mmol/L)]. Furthermore, to investigate whether POD influences mortality within 90 days after hip surgery. METHODS This is a post hoc analysis based on The TRIFE - a randomized controlled trial. Frail anemic patients from the Orthopedic Surgical Ward at Aarhus University Hospital were enrolled consecutively between January 18, 2010 and June 6, 2013. These patients (aged ≥65 years) had been admitted from nursing homes for unilateral hip fracture surgery. After surgery, 179 patients were included in this study. On the first day of hospitalization, all enrolled patients were examined for cognitive impairment (assessed by MMSE) and delirium (assessed by CAM). Delirium was also assessed on the tenth postoperative day. RESULTS The prevalence of delirium was 10 % in patients allocated to a liberal blood transfusion strategy (LB) and 21 % in the group with a restrictive blood transfusion strategy (RB). LB prevents development of delirium on day 10, compared to RB, odds ratio 0.41 (95 % CI 0.17-0.96), p = 0.04. Development of POD on day 10 increased the risk of 90-day death, hazard ratio 3.14 (95 % CI 1.72-5.78), p < 0.001. CONCLUSION In nursing home residents undergoing surgery for hip fracture, maintaining hemoglobin level above 11.3 g/dL reduces the rate of POD on day 10 compared to a RB. Development of POD is associated with increased mortality.

Abstract
UNLABELLED To evaluate the evidence for the resuscitation of patients with hip fracture in the preoperative or perioperative phase of their treatment and its impact on mortality. DESIGN We searched MEDLINE, EMBASE, CENTRAL and PROSPERO databases using a systematic search strategy for randomised trials and observational studies investigating the fluid resuscitation of any patient with hip fracture. No language limits were applied to the search, which was complemented by manually screening the reference lists of appropriate studies. OUTCOME MEASURES Mortality at 1 week, 30 days and 1 year following surgery. RESULTS Two hundred and ninety-eight citations were identified, and 12 full manuscripts were reviewed; no studies satisfied the inclusion criteria. The background literature showed that the mortality for these patients at 30 days is approximately 8.5% and that bone cement implantation syndrome is insufficient to explain this. The literature was explored to define the need for an interventional investigation into the preoperative resuscitation of patients with hip fracture. CONCLUSIONS Patients with hip fracture show similar physiological disturbance to major trauma patients. Nineteen per cent of patients presenting with hip fracture are hypoperfused and 50% show preoperative anaemia suggesting that under resuscitation is a common problem that has not been investigated. A properly conducted interventional trial could improve the outcome of these vulnerable patients.

Abstract
Bone and surgical site infections after osteosynthesis are notoriously difficult to manage and pose a tremendous burden in fracture management. In this article, we use the term osteosynthesis-associated infection (OAI) to refer to this clinical entity. While relatively few surgically treated fractures become infected, it is challenging to perform a rapid diagnosis. Optimal management strategies are complex and highly customized to each scenario and take into consideration the status of fracture union, the presence of hardware and the degree of mechanical stability. At present, a high level of relevant evidence is unavailable; most findings presented in the literature are based on laboratory work and non-randomized clinical studies. We present this overview of OAI in two parts: an examination of recent literature concerning OAI pathogenesis, diagnosis and classification and a review of treatment options.

Abstract
The management of major orthopedic surgery in the elderly prototypically reflects the perioperative risks of geriatric, often very frail patients reflecting an aging population. To improve outcome, the risks of anesthesia and surgery as well as of patient comorbidities must be thoroughly assessed and balanced using a multidisciplinary approach. Particular risks include cardiopulmonary morbidity, anemia, risk of hemorrhage and the management by anticoagulation, cerebral impairments as well as frailty and limited physiological reserves in general. Accordingly, an optimized therapy prior to, during, and after surgery will likely influence not only the immediate postoperative course but also hospital mortality and long-term outcome. Publications on the topic of perioperative management of geriatric patients are fortunately gaining in quality and quantity, not least against the background of the demographic developments. Accordingly, specific influencing factors relevant for perioperative management can be increasingly more identified. This short review summarizes the current state of knowledge to provide an overview and rationale for clinical decision making.

Abstract
BACKGROUND There is considerable uncertainty regarding the optimal haemoglobin threshold for the use of red blood cell (RBC) transfusions in anaemic patients. Blood is a scarce resource, and in some countries, transfusions are less safe than others because of a lack of testing for viral pathogens. Therefore, reducing the number and volume of transfusions would benefit patients. OBJECTIVES The aim of this review was to compare 30-day mortality and other clinical outcomes in participants randomized to restrictive versus liberal red blood cell (RBC) transfusion thresholds (triggers) for all conditions. The restrictive transfusion threshold uses a lower haemoglobin level to trigger transfusion (most commonly 7 g/dL or 8 g/dL), and the liberal transfusion threshold uses a higher haemoglobin level to trigger transfusion (most commonly 9 g/dL to 10 g/dL). SEARCH METHODS We identified trials by searching CENTRAL (2016, Issue 4), MEDLINE (1946 to May 2016), Embase (1974 to May 2016), the Transfusion Evidence Library (1950 to May 2016), the Web of Science Conference Proceedings Citation Index (1990 to May 2016), and ongoing trial registries (27 May 2016). We also checked reference lists of other published reviews and relevant papers to identify any additional trials. SELECTION CRITERIA We included randomized trials where intervention groups were assigned on the basis of a clear transfusion 'trigger', described as a haemoglobin (Hb) or haematocrit (Hct) level below which a red blood cell (RBC) transfusion was to be administered. DATA COLLECTION AND ANALYSIS We pooled risk ratios of clinical outcomes across trials using a random-effects model. Two people extracted the data and assessed the risk of bias. We conducted predefined analyses by clinical subgroups. We defined participants randomly allocated to the lower transfusion threshold as 'restrictive transfusion' and to the higher transfusion threshold as 'liberal transfusion'. MAIN RESULTS A total of 31 trials, involving 12,587 participants, across a range of clinical specialities (e.g. surgery, critical care) met the eligibility criteria. The trial interventions were split fairly equally with regard to the haemoglobin concentration used to define the restrictive transfusion group. About half of them used a 7 g/dL threshold, and the other half used a restrictive transfusion threshold of 8 g/dL to 9 g/dL. The trials were generally at low risk of bias .Some items of methodological quality were unclear, including definitions and blinding for secondary outcomes.Restrictive transfusion strategies reduced the risk of receiving a RBC transfusion by 43% across a broad range of clinical specialties (risk ratio (RR) 0.57, 95% confidence interval (CI) 0.49 to 0.65; 12,587 participants, 31 trials; high-quality evidence), with a large amount of heterogeneity between trials (I² = 97%). Overall, restrictive transfusion strategies did not increase or decrease the risk of 30-day mortality compared with liberal transfusion strategies (RR 0.97, 95% CI 0.81 to 1.16, I² = 37%; N = 10,537; 23 trials; moderate-quality evidence) or any of the other outcomes assessed (i.e. cardiac events (low-quality evidence), myocardial infarction, stroke, thromboembolism (high-quality evidence)). Liberal transfusion did not affect the risk of infection (pneumonia, wound, or bacteraemia). AUTHORS' CONCLUSIONS Transfusing at a restrictive haemoglobin concentration of between 7 g/dL to 8 g/dL decreased the proportion of participants exposed to RBC transfusion by 43% across a broad range of clinical specialities. There was no evidence that a restrictive transfusion strategy impacts 30-day mortality or morbidity (i.e. mortality at other points, cardiac events, myocardial infarction, stroke, pneumonia, thromboembolism, infection) compared with a liberal transfusion strategy. There were insufficient data to inform the safety of transfusion policies in certain clinical subgroups, including acute coronary syndrome, myocardial infarction, neurological injury/traumatic brain injury, acute neurological disorders, stroke, thrombocytopenia, cancer, haematological malignancies, and bone marrow failure. The findings provide good evidence that transfusions with allogeneic RBCs can be avoided in most patients with haemoglobin thresholds above 7 g/dL to 8 g/dL.

Abstract
Abstract
Background
Blood transfusions are associated with morbidity and mortality. However, restrictive thresholds could harm patients less able to tolerate anemia. Using a context-specific approach (according to patient characteristics and clinical settings), the authors conducted a systematic review to quantify the effects of transfusion strategies.
Methods
The authors searched MEDLINE, EMBASE, CENTRAL, and grey literature sources to November 2015 for randomized controlled trials comparing restrictive versus liberal transfusion strategies applied more than 24 h in adult surgical or critically ill patients. Data were independently extracted. Risk ratios were calculated for 30-day complications, defined as inadequate oxygen supply (myocardial, cerebral, renal, mesenteric, and peripheral ischemic injury; arrhythmia; and unstable angina), mortality, composite of both, and infections. Statistical combination followed a context-specific approach. Additional analyses explored transfusion protocol heterogeneity and cointerventions effects.
Results
Thirty-one trials were regrouped into five context-specific risk strata. In patients undergoing cardiac/vascular procedures, restrictive strategies seemed to increase the risk of events reflecting inadequate oxygen supply (risk ratio [RR], 1.09; 95% CI, 0.97 to 1.22), mortality (RR, 1.39; 95% CI, 0.95 to 2.04), and composite events (RR, 1.12; 95% CI, 1.01 to 1.24—3322, 3245, and 3322 patients, respectively). Similar results were found in elderly orthopedic patients (inadequate oxygen supply: RR, 1.41; 95% CI, 1.03 to 1.92; mortality: RR, 1.09; 95% CI, 0.80 to 1.49; composite outcome: RR, 1.24; 95% CI, 1.00 to 1.54—3465, 3546, and 3749 patients, respectively), but not in critically ill patients. No difference was found for infections, although a protective effect may exist. Risk estimates varied with successful/unsuccessful transfusion protocol implementation.
Conclusions
Restrictive transfusion strategies should be applied with caution in high-risk patients undergoing major surgery.

Abstract
OBJECTIVE To compare patient outcomes of restrictive versus liberal blood transfusion strategies in patients with cardiovascular disease not undergoing cardiac surgery. DESIGN Systematic review and meta-analysis. DATA SOURCES Randomised controlled trials involving a threshold for red blood cell transfusion in hospital. We searched (to 2 November 2015) CENTRAL, Medline, Embase, CINAHL, PubMed, LILACS, NHSBT Transfusion Evidence Library, ClinicalTrials.gov, WHO International Clinical Trials Registry Platform, ISRCTN Register, and EU Clinical Trials Register. Authors were contacted for data whenever possible. TRIAL SELECTION Published and unpublished randomised controlled trials comparing a restrictive with liberal transfusion threshold and that included patients with cardiovascular disease. DATA EXTRACTION AND SYNTHESIS Data extraction was completed in duplicate. Risk of bias was assessed using Cochrane methods. Relative risk ratios with 95% confidence intervals were presented in all meta-analyses. Mantel-Haenszel random effects models were used to pool risk ratios. MAIN OUTCOME MEASURES 30 day mortality, and cardiovascular events. RESULTS 41 trials were identified; of these, seven included data on patients with cardiovascular disease. Data from a further four trials enrolling patients with cardiovascular disease were obtained from the authors. In total, 11 trials enrolling patients with cardiovascular disease (n=3033) were included for meta-analysis (restrictive transfusion, n=1514 patients; liberal transfusion, n=1519). The pooled risk ratio for the association between transfusion thresholds and 30 day mortality was 1.15 (95% confidence interval 0.88 to 1.50, P=0.50), with little heterogeneity (I(2)=14%). The risk of acute coronary syndrome in patients managed with restrictive compared with liberal transfusion was increased (nine trials; risk ratio 1.78, 95% confidence interval 1.18 to 2.70, P=0.01, I(2)=0%). CONCLUSIONS The results show that it may not be safe to use a restrictive transfusion threshold of less than 80 g/L in patients with ongoing acute coronary syndrome or chronic cardiovascular disease. Effects on mortality and other outcomes are uncertain. These data support the use of a more liberal transfusion threshold (>80 g/L) for patients with both acute and chronic cardiovascular disease until adequately powered high quality randomised trials have been undertaken in patients with cardiovascular disease.
