Introduction: In recent years, resource-saving handling of allogeneic blood products and a reduction of transfusion rates in adults has been observed. However, comparable published national data for transfusion practices in pediatric patients are currently not available. In this study, the transfusion rates for children and adolescents were analyzed based on data from the Federal Statistical Office of Germany during the past 2 decades. Methods: Data were queried via the database of the Federal Statistical Office (Destasis). The period covered was from 2005 to 2018, and those in the sample group were children and adolescents aged 0–17 years receiving inpatient care. Operation and procedure codes (OPS) for transfusions, procedures, or interventions with increased transfusion risk were queried and evaluated in detail. Results: In Germany, 0.9% of the children and adolescents treated in hospital received a transfusion in 2018. A reduction in transfusion rates from 1.02% (2005) to 0.9% (2018) was observed for the total collective of children and adolescents receiving inpatient care. Increases in transfusion rates were recorded for 1- to 4- (1.41–1.45%) and 5- to 10-year-olds (1.24–1.33%). Children under 1 year of age were most frequently transfused (in 2018, 40.2% of the children were cared for in hospital). Transfusion-associated procedures such as chemotherapy or machine ventilation and respiratory support for newborns and infants are on the rise. Conclusion: Transfusion rates are declining in children and adolescents, but the reasons for increases in transfusion rates in other groups are unclear. Prospective studies to evaluate transfusion rates and triggers in children are urgently needed.
Background: Patient Blood Management (PBM) is a systematic quality improving clinical model to reduce anemia and avoid transfusions in all kinds of clinical settings. Here, we investigated the potential of PBM in oncologic surgery and hypothesized that PBM improves 2-year overall survival (OS).
Methods: Retrospective analysis of patients 2 years before and after PBM implementation. The primary endpoint was OS at 2 years after surgery. We identified a sample size of 824 to detect a 10% improvement in survival in the PBM group.
Results: The analysis comprised of 836 patients that underwent oncologic surgery, 389 before and 447 after PBM, was implemented. Patients in the PBM+ presented significantly more frequent with normal hemoglobin values before surgery than PBM− (56.6 vs. 35.7%; p < 0.001). The number of transfusions was significantly reduced from 5.5 ± 11.1 to 3.0 ± 6.9 units/patient (p < 0.001); moreover, the percentage of patients being transfused during the clinic stay was significantly reduced from 62.4 to 40.9% (p < 0.001). Two-year OS was significantly better in the PBM+ and increased from 67.0 to 80.1% (p = 0.001). A normal hemoglobin value (> 12 g/dl in female and > 13 g/dl in male) before surgery (HR 0.43, 95% CI 0.29–0.65, p < 0.001) was the only independent predictive factor positively affecting survival.
Conclusions: PBM is a quality improvement tool that is associated with better mid-term surgical oncologic outcome. The root cause for improvement is the increase of patients entering surgery with normal hemoglobin values.
Background: Cell salvage is commonly used as part of a blood conservation strategy. However concerns among clinicians exist about the efficacy of transfusion of washed cell salvage.
Methods: We performed a meta-analysis of randomized controlled trials in which patients, scheduled for all types of surgery, were randomized to washed cell salvage or to a control group with no cell salvage. Data were independently extracted, risk ratio (RR), and weighted mean differences (WMD) with 95% confidence intervals (CIs) were calculated. Data were pooled using a random effects model. The primary endpoint was the number of patients exposed to allogeneic red blood cell (RBC) transfusion.
Results: Out of 1140 search results, a total of 47 trials were included. Overall, the use of washed cell salvage reduced the rate of exposure to allogeneic RBC transfusion by a relative 39% (RR = 0.61; 95% CI 0.57 to 0.65; P < 0.001), resulting in an average saving of 0.20 units of allogeneic RBC per patient (weighted mean differences [WMD] = -0.20; 95% CI -0.22 to -0.18; P < 0.001), reduced risk of infection by 28% (RR = 0.72; 95% CI 0.54 to 0.97; P = 0.03), reduced length of hospital stay by 2.31 days (WMD = -2.31; 95% CI -2.50 to -2.11; P < 0.001), but did not significantly affect risk of mortality (RR = 0.92; 95% CI 0.63 to 1.34; P = 0.66). No statistical difference could be observed in the number of patients exposed to re-operation, plasma, platelets, or rate of myocardial infarction and stroke.
Conclusions: Washed cell salvage is efficacious in reducing the need for allogeneic RBC transfusion and risk of infection in surgery.
