Surgical site infection in severe trauma patients in intensive care: epidemiology and risk factors

BackgroundSevere trauma is the leading cause of disability and mortality in the patients under 35 years of age. Surgical site infections (SSI) represent a significant complication in this patient population. However, they are often inadequately investigated, potentially impacting the quality of patient outcomes. The aim of this study was to investigate the epidemiology of SSI and risk factors in severe trauma patients.MethodsWe conducted a multicenter retrospective cohort study screening the severe trauma patients (STP) admitted to two intensive care units of an academic institution in Marseille between years2018 and 2019. Those who underwent orthopedic or spinal surgery within 5 days after admission were included and classified into two groups according to the occurrence of SSI (defined by the Centers for Disease Control (CDC) international diagnostic criteria) or not. Our secondary goal was to evaluate STP survival at 48 months, risk factors for SSI and microbiological features of SSI.ResultsForty-seven (23%) out of 207 STP developed an SSI. Mortality at 48-months did not differ between SSI and non-SSI patients (12.7% vs. 10.0%; p = 0.59). The fractures of 22 (47%) severe trauma patients with SSI were classified as Cauchoix 3 grade and 18 (38%) SSI were associated with the need for external fixators. Thirty (64%) severe trauma patients with SSI had polymicrobial infection, including 34 (72%) due to Gram-positive cocci. Empirical antibiotic therapy was effective in 31 (66%) cases. Multivariate analysis revealed that risk factors such as low hemoglobin, arterial oxygenation levels, hyperlactatemia, high serum creatinine and glycemia, and Cauchoix 3 grade on the day of surgery were associated with SSI in severe trauma patients. The generated predictive model showed a good prognosis performance with an AUC of 0.80 [0.73–0.88] and a high NPV of 95.9 [88.6–98.5] %.ConclusionsOur study found a high rate of SSI in severe trauma patients, although SSI was not associated with 48-month mortality. Several modifiable risk factors for SSI may be effectively managed through enhanced perioperative monitoring and the implementation of a patient blood management strategy.

Intraoperative cell salvage reduces postoperative allogeneic blood transfusion and shortens off-bed time in simultaneous bilateral total hip arthroplasty: a single-center retrospective study

BackgroundSimultaneous bilateral total hip arthroplasty (SI-THA) results in more blood loss and a greater need for postoperative allogeneic blood transfusion (ABT). Previous studies have reported that multimodal patient blood management (PBM) strategies were associated with a smaller effect of intraoperative cell salvage (ICS) in unilateral total hip arthroplasty. However, there are few studies on the role of ICS in SI-THA. This study aims to explore the effect of ICS with multimodal PBM strategies on SI-THA and to identify risk factors associated with ABT.MethodsThis retrospective matched cohort study included 72 patients in the ICS group and 72 patients in the control group who were matched according to age, sex, and year of hospitalization. Demographic data, hematological indicators, blood loss, and ABT were compared between the two groups. Logistic regression analysis was performed to identify independent risk factors for postoperative ABT. Postoperative outcomes were also recorded.ResultsIn the cohort of 144 patients, 27 patients (37.5%) in the ICS group while 45 patients (62.5%) in the control group received postoperative ABT after SI-THA. Compared with the control group, the ICS group showed significant differences in terms of blood loss, postoperative hemoglobin and hematocrit. The transfused volume of allogeneic red blood cells per ABT patient was also lower in the ICS group. Multivariate logistic regression analysis indicated that sex, the utilization of ICS, and preoperative hematocrit level were identified as independent factors associated with postoperative ABT. The utilization of ICS significantly shortened off-bed time and length of hospital stay, but had no effect on early pain and functional outcomes.ConclusionThe utilization of ICS can significantly affect postoperative ABT in SI-THA patients with multimodal PBM strategies. Sex, the utilization of ICS and preoperative hematocrit level were identified as independent factors associated with postoperative ABT. The utilization of ICS promoted weight-bearing functional exercises, but had no effect on early outcomes.

Patient Blood Management Program Implementation: Comprehensive Recommendations and Practical Strategies.

Blood transfusion is one of the most common medical practices worldwide. However, current scientific literature has shown that the immunomodulatory effects of blood transfusion are associated with an increased likelihood of infection, prolonged hospitalization, and morbimortality. Also, it means high costs for healthcare systems. In this context, acknowledging that blood transfusions are essentially heterologous cell transplantations, the use of therapeutic options has gained strength and is collectively known as the patient blood management (PBM) program. PBM is an approach based on three main pillars: (1) treating anemias and coagulopathies in an optimized manner, especially in the preoperative period; (2) optimizing perioperative hemostasis and the use of blood recovery systems to avoid the loss of the patient's blood; (3) anemia tolerance, with improved oxygen delivery and reduced oxygen demand, particularly in the postoperative period. Current scientific evidence supports the effectiveness of PBM by reducing the need for blood transfusions, decreasing associated complications, and promoting more efficient and safer blood management. Thus, PBM not only improves clinical outcomes for patients but also contributes to the economic sustainability of healthcare systems. The aim of this review was to summarize PBM strategies in a comprehensive, evidence-based approach through a systematic and structured model for PBM implementation in tertiary hospitals. The recommendations proposed herein are from researchers and experts of a high-complexity university hospital in the network of the Sistema Único de Saúde, presenting itself as a strategy that can be followed as a guideline for PBM implementation in other settings.

Effects of Fibrinogen Concentrate Supplementation on Postoperative Bleeding in Infants Undergoing Complex Cardiac Surgery.

The use of allogeneic blood products to restore hemostasis during pediatric cardiac surgery is associated with major risks. Consequently, there has been a growing interest in new patient blood management strategies, such as those based on the use of fibrinogen concentrate (FC). Accumulating evidence has shown FC supplementation to be safe and effective. Nevertheless, no guidelines are available on using FC in the pediatric setting, and few objective evaluations have been provided in clinical practice. The endpoint of this monocenterretrospective study was the hemostatic effect of additional FC in infants undergoing complex cardiac surgery with cardiopulmonary bypassto manage persistent clinically relevant bleeding. After weaning from cardiopulmonary bypass and after protamine administration, patients were transfused with conventional allogeneic products such as packed red blood cells, fresh frozen plasma (FFP), and platelets. In the case of redo surgery, according to the institutional protocol, patients also received tranexamic acid. In case of clinically persistent relevant bleeding, according to the anesthesiologist's judgment and thromboelastography, patients received FC supplementation (group with FC) or further FFP transfusions without receiving FC supplementation (group without FC). The primary endpoint was the hemostatic effects of FC. Secondary endpoints were the functional hypofibrinogenemia threshold value (expressed as maximum amplitude fibrinogen, MA-Fib) and postoperative MA-Fib, fibrinogenemia, intraoperative transfusions, and adverse events (AEs). In total, 139 patients who underwent cardiac surgery with CPB and aged less than 2 years were enrolled: 70 patients received allogeneic blood products and FC supplementation (group FC); 69 patients received allogeneic products without FC supplementation (group without FC). Patients that received FC supplementation were characterized by a significantly longer time of extracorporeal circulation (p < 0.001) and aortic cross-clamping (p < 0.001), a significantly lower minimum temperature (p = 0.011), increased use of concentrated prothrombin complex (p = 0.016) and tranexamic acid (p = 0.010), and a significantly higher amount of packed red blood cells, platelets (p < 0.001) and fresh frozen plasma (p = 0.03). Postoperative bleeding and severe bleeding were not statistically different between patients treated with FC and those not treated with FC supplementation (p = 0.786 and p = 0.695, respectively); after adjustment, a trend toward reduced bleeding can be observed with FC (p = 0.064). Overall, 88% of patients with severe bleeding had MA-Fib < 10 mm; a moderate association between severe bleeding and MA-Fib (odds ratio 1.7, 95% CI 0.5-6.5, p = 0.425) was found. Increased MA-Fib and postoperative fibrinogen were higher in the FC group (p = 0.003 and p < 0.001, respectively) than in FFP. AEs in the FC group were comparable to those observed in less complicated surgeries. Our results suggest a potential role of FC in complex surgery in maintaining postoperative bleeding at a level comparable to less complicated surgical procedures and favoring the increase in postoperative MA-Fib and fibrinogen.

Current approach to the management of preoperative iron deficiency anemia in colorectal cancer patients: a review of literature.

&lt;b&gt;Introduction:&lt;/b&gt; The prevalence of preoperative anemia is the highest in the group of colorectal cancer (CRC) patients and may reach over 75%. The prevalence of anemia in CRC patients increases even further following surgery. Approximately 75-80% of anemic CRC patients present with absolute or functional iron deficiency (ID). Preoperative anemia constitutes an independent risk factor for allogeneic blood transfusion (ABT), postoperative complications, prolonged length of hospital stay, and increased mortality. ABT is itself associated with increased morbidity and mortality.&lt;b&gt;Aim:&lt;/b&gt; The aim of this review article was to present the pathophysiology and the current approach to the diagnostics and treatment of preoperative iron deficiency anemia (IDA) in CRC patients.&lt;b&gt;Material and methods:&lt;/b&gt; Extensive search of medical literature databases was performed (Pubmed, Embase). The key words that were used were as follows: CRC, colorectal surgery, ID, IDA, intravenous iron, Patient Blood Management (PBM).&lt;b&gt;Results:&lt;/b&gt; There are several laboratory parameters that can be used for IDA diagnosis, however, the simplest and most cost- -effective is reticulocyte hemoglobin equivalent (RET-He). Pathophysiologic features of IDA in CRC patients favor treatment with intravenous, as opposed to oral, iron formulations. Applying PBM strategies minimizes the exposure to ABT.&lt;b&gt;Conclusions:&lt;/b&gt; Preoperative IDA is highly prevalent among CRC patients. Preoperative anemia is an independent risk factor for ABT, increased morbidity and mortality, as well as prolonged hospital length of stay. The same negative consequences are associated with ABT. Therefore, preoperative IDA in CRC patients needs to be screened for, diagnosed, and treated before surgery. Effective treatment of preoperative IDA in CRC patients is with intravenous iron formulations. ABT should be the treatment of last resort due to the risk of negative clinical consequences, including an increased rate of cancer recurrence.

Impact of Intraoperative Allogeneic Platelet Transfusion on Healthcare-Associated Infections in Cardiac Surgery: Insights From a Large Single-Center Cohort Study

ObjectivesDespite significant improvement in patient blood management-cardiac surgery remains a high hemorrhagic risk procedure. Platelet transfusion is commonly used to treat thrombocytopenia-induced perioperative bleeding. Allogeneic platelet transfusion may induce transfusion-related immunomodulation. However, its association with postoperative healthcare-associated infections is still a matter of debate. Our objective was to evaluate the impact of allogeneic platelet transfusion during cardiac surgery on postoperative HAI incidence. DesignRetrospective cohort study SettingTertiary referral academic center ParticipantsPatients undergoing cardiac surgery from 2012 to 2018. InterventionsNone Measurements and Main ResultsIntraoperative platelet transfusion was defined as exposure in a causal model. The primary outcome was the incidence of healthcare-associated infections-comprised of bloodstream infection-hospital-acquired pneumonia and surgical-site infection. Among 7662 included patients, 528 (6.8%) were exposed to intraoperative platelet transfusion and 329 (4.3%) developed 454 postoperative infections. Bloodstream infection affected 106 (1.4%) patients, hospital-acquired pneumonia 174 (2.3%) and surgical-site infection 148 (1.9%). Intraoperative platelet transfusion was associated with an increased risk of bloodstream infection after adjustment by multivariable logistic regression (OR 2.85; 95%CI (1.40-5.8); p=0.004; n=7662), propensity score matching (OR 3.95; 95%CI (1.57-12.0), p=0.007; n=766) and propensity score overlap weighting (OR 3.04; 95%CI (1.51-6.1), p=0.002; n=7762). Surgical-site infection and hospital-acquired pneumonia were not significantly increased by platelet transfusion. ConclusionsOur results suggest that intraoperative allogeneic platelet transfusion is a risk factor for bloodstream infection after cardiac surgery. These results support the development of patient blood management strategies aiming at minimizing perioperative platelet transfusion in cardiac surgery.

Impact of Patient Blood Management on Red Blood Cell Utilization in an Urban Community Teaching Hospital: A Seven-Year Retrospective Study.

This study aimed to showcase how implementing a patient blood management (PBM) program effectively cuts unnecessary red blood cell (RBC) transfusions in a New York City urban community teaching hospital. Analyzing seven years from 2013 to 2019, a retrospective review of RBC transfusions was conducted. Following the introduction of PBM, considerable improvements were observed annually. These included a drop in mean pretransfusion hemoglobin levels from 7.26 g/dL (2013) to 6.58 g/dL (2019), a 34% reduction in yearly RBC unit transfusions, and fewer units given to patients with pre-Hgb levels ≥ 7 g/dL (from 1210 units in 2013 to 310 units in 2019). Furthermore, this study noted a decline in two-unit RBC orders when Hgb levels were ≥ 7 g/dL from 65 orders in 2013 to merely 3 in 2019. The estimated total cost savings attributed to the six-year PBM program duration after full implementation in 2014 amounted to USD 2.1 million. Overall, PBM implementation significantly decreased RBC transfusions and enhanced transfusion practices. The findings emphasize that successful PBM strategies do not always necessitate extensive resources or increased budgets but instead rely on the application of intuitive methods, as evidenced by this study.

Rational Transfusion in Clinical Practice: Walking the Tight Rope

Transfusion therapy has undergone a significant evolution from whole blood transfusions to highly specialized blood component therapy. There is enough evidence in the literature that estimates that half of the transfusions given to the patients were actually not required as their hemoglobin can be improved with the help of alternative methods. The introduction of patient blood management (PBM) marks a paradigm shift in clinical transfusion practice and anemia management, emphasizing a patient-centric approach. PBM strategies aim to preserve and improve the patient’s blood, thereby reducing the need for allogeneic blood transfusions. PBM strategies include treating anemia, correcting coagulopathy, and minimizing blood loss. Every healthcare facility should plan to implement PBM as a multidisciplinary and multi-professional program, requiring collaboration from clinicians, public health professionals, and hospital administration. Thus, PBM implementation requires a comprehensive business plan, evidence-based transfusion guidelines, education, and a clinical decision support system. Data acquisition, analysis, audits, and reports play a crucial role in continuously improving the healthcare system and enhancing patient safety.

Advancing Patient Blood Management: Evaluation of Ferric Derisomaltose in a Tertiary Hospital

ABSTRACT Background and Objectives: One of the aims of patient blood management (PBM) programs is to improve patient outcomes by managing anemia and avoiding unnecessary blood transfusions. Ferric derisomaltose (FDI) is a treatment that allows for the injection of high doses of iron in a shorter time, which makes it a promising approach for correcting iron-deficiency anemia (IDA) more efficiently. This study aimed to assess the safety, effectiveness, and cost implications of FDI in a PBM program and its impact on transfusion requirements. Methods: A retrospective analysis was conducted on electronic medical records of adult patients diagnosed with IDA who received FDI as part of a PBM strategy in a tertiary hospital from November 2019 to June 2021. Descriptive statistics summarized patient characteristics and outcomes. Changes in hemoglobin (Hb) levels were evaluated using a paired t-test. Cost analysis included direct and indirect expenses associated with FDI administration compared to alternative treatments. Results: Out of the initially enrolled 110 patients, 67 were included in the analysis. A mean increase in Hb levels of 2.7 ± 1.9 g/dL was observed as early as 4 days post-FDI administration. The majority of patients (94.0%) tolerated FDI well, with only a few experiencing mild adverse reactions. Following FDI administration, blood transfusion was avoided by 88% of patients. Cost analysis revealed that while FDI demonstrated higher direct costs compared to alternative treatments, its potential for lower total costs became apparent when considering both direct and indirect expenses. Conclusions: FDI demonstrated promising results in rapidly correcting IDA within a PBM program. It reduced the need for blood transfusions, with the treatment being well-tolerated by patients. The inclusion of FDI administration in PBM programs offers a convenient, efficient, and potentially cost-effective approach to managing IDA.

Anesthetic management of a huge retroperitoneal leiomyoma: a case report

BackgroundRetroperitoneal leiomyomas are rare, with just over 100 cases reported in the literature. Perioperative management of retroperitoneal leiomyomas can be challenging due to the large tumor size and the risk of hemorrhage.Case presentationWe report a case of a 40-year-old Han woman with a 40-cm retroperitoneal leiomyoma. General anesthesia was performed for the surgical resection. Key flow parameters like cardiac output and stroke volume variation, as shown by the Vigileo™-FloTrac™ system, enabled the anesthesiologist to implement goal-directed fluid optimization. Acute normovolemic hemodilution and cell salvage technique were used resulting in a successful en bloc tumor resection with a 6000-mL estimated blood loss. Although the patient experienced postoperative bowel obstruction, no other significant complications were observed.ConclusionAdvanced hemodynamic monitoring and modern patient blood management strategies are particularly helpful for anesthetic management of huge retroperitoneal leiomyomas.

Low-Volume Acute Normovolemic Hemodilution Does Not Reduce Allogeneic Red Blood Cell Transfusion in Cardiac Surgery in the Modern Era of Patient Blood Management: A Propensity Score-Matched Cohort Study

Patients undergoing cardiac surgery often require blood transfusions, which are associated with increased morbidity and mortality. Patient blood management (PBM) strategies, including acute normovolemic hemodilution (ANH), have been implemented to minimize allogeneic transfusion requirements. Older studies suggested that ANH is associated with reduced transfusions; however, its effectiveness in the modern era of PBM remains unclear. This was a retrospective cohort study. The study was held at a single university hospital. 542 patients who underwent elective cardiac surgery with cardiopulmonary bypass (CPB) using low-priming-volume circuits between January 2017 and March 2022. Patients who received ANH were matched with those who did not receive ANH, using propensity scores. The primary outcome was the proportion of patients who received perioperative red blood cell (RBC) transfusion. Of the 542 eligible patients, 49 ANH cases were propensity-score matched to 97 controls. The median ANH volume was 450 mL (IQR, 400-800 mL). There was no significant difference in perioperative RBC transfusion rates between the 2 groups (24.5% in the ANH group vs 30.9% in the control group, p=0.42). The odds ratio for perioperative RBC transfusion in the ANH group versus the control group was 0.72 (95% CI, 0.32-1.55, p=0.42). Low-volume ANH was not associated with a significant reduction in perioperative allogeneic RBC transfusion during cardiac surgery with CPB using low-priming-volume circuits. The benefits of low-volume ANH in reducing the requirement for RBC transfusion in the modern era of PBM may be smaller than reported previously.

Data and Metrics for Patient Blood Management: A Narrative Review and Practical Guide.

Data collection, analysis, and reporting are fundamental for a successful hospital-based patient blood management program; however, very little has been published on the topic. Our aim was to synthesize evidence from a literature review to provide a detailed, practical list of outcome metrics, and the required data collection(s) to inform implementation. Ovid MEDLINE and PubMed were searched for any full-text original research articles published from inception to the year 2020. We included any studies reporting the implementation of interventions or programs study authors defined as "patient blood management" and extracted information on data collected and metrics reported. We included 45 studies describing the implementation of a patient blood management program and/or strategies. The outcomes reported by these studies were grouped into 1 of 36 metrics. We compiled a list of 65 relevant data elements to collect, and their potential source hospital information systems: patient administration, laboratory, transfusion/blood bank, operating room, pharmacy, emergency department, and intensive care unit. We further categorized patient blood management data systems into basic, intermediate, and advanced based on the combination of different information systems sourced. The results of this review can be used to inform patient blood management programs in planning what data collection(s) are needed, where these data can be sourced from, and how they can be analyzed.

Lessons learned from patient outcomes when lowering hemoglobin transfusion thresholds during COVID-19 blood shortages.

This study examines whether patient outcomes were affected when the hemoglobin (Hb) transfusion threshold was lowered by 1 g/dL during COVID-19-related blood shortages. Outcomes of lowered Hb thresholds (from <7 to <6 g/dL) were defined by 14-month intervals in 2 patient groups (prepandemic [January 2019-February 2020] and pandemic [April 2020-May 2021]). We evaluated patient admissions, pretransfusion (if transfused) or nadir admission (if not transfused) Hb levels between 5.0 and 8.0 g/dL, and total red blood cell (RBC) transfusions during admission (if transfused). Baseline variables and outcomes were selected from electronic health records. Primary COVID-19-related admissions were excluded. Regression analysis was conducted to determine outcomes. Those in the prepandemic group (1976) and pandemic group (1547) were transfused. Fewer RBCs (2186, vs 3337) were used in the prepandemic group than in the pandemic group, respectively. Those in the prepandemic group had significantly higher rates of hypertension and diabetes as well as more smokers. Significant differences were observed when comparing the number of procedures and incidence of sepsis between the patient groups. Similar patterns were observed for the not transfused and transfused subgroups. Patient outcomes were not affected after implementing lower Hb pretransfusion thresholds. Although confounding factors were mitigated, some may have been associated with procedures or sepsis. Proactive patient blood management strategies during COVID-19-related blood shortages may include adopting lower Hb thresholds.

Project S.T.O.P (Stop the Over-ordering of Platelets): An initiative to reduce platelet wastages for pediatric open-heart surgeries

IntroductionDue to a national policy change in the management of unused platelet units from September 2018, there was a drastic increase in the number of platelet units wasted in our institution. MethodsUsing Quality Improvement (QI) tools, platelet wastages from pediatric heart surgeries was identified as a priority area to work on. An intervention based on the creation of ‘Order Sets’ for pediatric open-heart surgeries was implemented, standardizing standby platelet orders based on type of surgery and patient weight. ResultsThis intervention led to a dramatic improvement in the number of platelets ordered on standby, and consequently a decrease in platelet wastage from 47.6% to 16.9% for pediatric open-heart surgeries, without any reported adverse events. ConclusionWith the creation of Order Sets and continuous education, it was possible to eradicate the practice of requesting unnecessary standby platelets for surgeries. This is an effective patient blood management (PBM) strategy resulting in a significant decrease in platelet wastage rate and substantial cost savings.

Blood management practices during rapid transfer of urgent trauma patients pre- and post-implementation of ROTEM®-guided transfusion

Objective The ‘Red Blanket’ protocol fast tracks trauma patients with severe blood loss to the designated trauma operating theatre directly from the hospital helipad or Emergency Department. This study aimed to assess the impact of patient blood management (PBM) strategies on severely injured trauma patients treated under the ‘Red Blanket’ protocol at a quaternary referral hospital. Methods This retrospective review was conducted on all urgent trauma cases that were treated under the ‘Red Blanket’ protocol in a ten-year period between January 2007 and December 2017. The use of blood products and patient outcomes was compared between the 3.5-year periods pre- and post-ROTEM® implementation on 30th June 2014 (Jan 2011-June 2014 versus July 2014-Dec 2017). Results During the study period, 120 trauma patients were treated under the ‘Red Blanket’ protocol at our institution. Intention to treat analysis showed a reduction in fresh frozen plasma usage following the introduction of ROTEM®-guided transfusion. Furthermore, subgroup analysis suggested reduced blood product usage in patients who survived. Conclusions Patient blood management is a coordinated package of systems and tools, including education, patient logistics, anaemia management, intraoperative cell salvage, rotational thromboelastometry and massive transfusion protocols that together conserve blood products and improve outcomes. The implementation of ROTEM®-guided transfusion demonstrated a reduction in fresh frozen plasma usage.

Multivariable statistical models to predict red cell transfusion in elective surgery.

Predicting red cell transfusion may assist in identifying those most likely to benefit from patient blood management strategies. Our objective was to identify a simple statistical model to predict transfusion in elective surgery from routinely available data. Our final multicentre cohort consisted of 42,546 patients and contained the following potential predictors of red cell transfusion known prior to admission: patient age, sex, pre-admission hemoglobin, surgical procedure, and comorbidities. Missing data were handled by multiple imputation methods. The outcome measure of interest was administration of a red cell transfusion. We used multivariable logistic regression models to predict transfusion, and evaluated the performance by applying a 10-fold cross-validation. Model accuracy was assessed by comparing the area under the receiver operating characteristics curve. After applying an optimal probability cut-off we measured model accuracy, sensitivity, specificity, positive predictive value, and negative predictive value. 7.0% (n=2,993) of the study population received a red cell transfusion. Our most simple model predicted red cell transfusion based on admission hemoglobin and surgical procedure with a multiply imputed estimated area under the curve of 0.862 (0.856, 0.864). The estimated accuracy, sensitivity, specificity, positive predictive, and negative predictive values at the probability cut-off of 0.4 were 0.934, 0.257, 0.986, 0.573, and 0.946 respectively. A small number of variables available prior to admission can predict red cell transfusion with very good accuracy. Our model can be used to flag high-risk patients most likely to benefit from pre-operative patient blood management measures.

A survey on preoperative autologous blood donation policy in bone marrow stem cell donors in Italy.

The high safety of homologous blood components, together with the introduction of the Patient Blood Management strategy, has led to the progressive abandonment of preoperative autologous blood donation (PAD) in surgery. Furthermore, recent scientific publications provide evidence about the non-usefulness of PAD in the collection of hematopoietic stem cells (HSC) from bone marrow (BM), also in consideration of harvest procedure safety. Nevertheless, no conclusive studies have been published yet. Blood Establishments (BE) and Bone Marrow Collection Centers (BMCC) participated in a specific qualitative survey proposed by Italian National Blood and Transplant centers with the support of the relevant Italian Scientific Societies. The survey aimed at evaluating the policy adopted for PAD in related and unrelated adult HSC donors in Italy during the period 2018-2020. Forty-one BE corresponding to 37 BMCC filled in the questionnaire. Of 830 BM donors, 661 (80%) underwent 1063 PAD (mean 1.6 PAD/donor). The remaining 169 donors (20%) underwent BM harvest without PAD. No serious adverse events were reported for either donor group. In the case of ineligibility of donors for the PAD program, due to low hemoglobin values, 7/10 centers shifted donors to peripheral blood stem cell collection and three centers chose a different donor. Remarkably, only 51% of the PAD units requested were eventually transfused during the BM harvest process. Finally, the iron support policy among centers was heterogeneous. The results of this survey show that PAD is heterogeneously applied in Italian BMCC, as in other countries. However, all BMCC except two are willing to adopt a Patient Blood Management strategy as an alternative approach to adult related and unrelated BM donor harvests.

Improving Patient Blood Management Programs: An Implementation Science Approach.

Organized patient blood management (PBM) programs function in numerous hospitals and health systems around the world contributing to improved patient outcomes as well as increased patient engagement, decreased resource use, and reductions in health care costs. PBM "programming" ranges from the implementation of single strategies/initiatives to comprehensive programs led by dedicated clinicians and PBM committees, employing the use of multiple PBM strategies. Frontline health care professionals play an important role in leading, implementing, operationalizing, measuring, and sustaining successful PBM programs. In this article, we provide practical implementation guidance to support key clinical, administrative, leadership, and structural elements required for the safe and comprehensive delivery of care in PBM programs at the local level.

Patient Blood Management programs for post-partum hemorrhage.

Patient blood management (PBM) strategies aim to maintain hemoglobin concentration, optimize hemostasis, and minimize blood loss to improve patient outcomes. Because postpartum hemorrhage (PPH) is a leading cause of maternal mortality and blood product utilization, PBM principles can be applied in its therapeutic approach. First, pre-operative identification of risk factors for PPH and identification of peri-delivery anemia should be conducted. Iron supplementation should be used to optimize hemoglobin concentration before delivery; it can also be used to treat anemia in the postpartum period after severe PPH. Both acute normovolemic hemodilution and intraoperative cell salvage can be effective techniques to reduce allogeneic blood transfusion during or after surgical procedures. Furthermore, these strategies appear to be safe when used in the pregnant population.

Patient blood management using dedicated personnel in the operating room-you get what you pay for.

A patient blood management (PBM) strategy can be applied to the process of intraoperative cell salvage for re-infusion during surgery. Stoneham et al. describe an effective PBM strategy applied to abdominal aortic aneurysm repair and emphasise the importance of a qualified and experienced intraoperative cell salvage practitioner to improve the safety and effectiveness of the approach.
