Associations of a Preoperative Anemia and Suboptimal Iron Stores Screening and Management Clinic in Colorectal Surgery With Hospital Cost, Reimbursement, and Length of Stay: A Net Cost Analysis.

BACKGROUND: In 2016, a preoperative clinic was implemented to screen, evaluate, and manage anemia and suboptimal iron stores at a major tertiary care medical center in Western Australia. Few studies compare the costs and reimbursements associated with preoperative anemia and suboptimal iron stores management. The objective of our study was to conduct a net cost analysis associated with the implementation of this clinic. METHODS: We designed a retrospective cohort study involving elective colorectal surgical admissions over a 3-year period. The baseline year selected was the 2015-2016 financial year, with outcomes in the 2016-2017 and 2017-2018 year compared to baseline. The study perspective was the Western Australian Health System. Hospital costs were extracted from the health service clinical costing system, which captures costs at the admission level. The primary outcome was net cost, defined as gross cost minus reimbursement (or funding) received. RESULTS: Our 3-year study included 544 admissions for elective colorectal surgery. After the implementation of the preoperative clinic, 73.4% (n = 257) of admissions were screened for anemia and suboptimal iron stores, and 31.4% (n = 110) received intravenous iron. In our adjusted analysis, when comparing the final year (2017-2018) with baseline (2015-2016), the units of red blood cells transfused per admission decreased 53% (142 vs 303 units per 1000 discharges; P = .006), and mean hospital length of stay decreased 15% (7.7 vs 9.1 days; P = .008). When comparing the final year with baseline, rectal resection admissions were associated with a mean decrease in the net cost of Australian dollar (A$) 7619 (95% confidence interval, 4230-11,008; P < .001) between 2015-2016 and 2017-2018. For small and large bowel procedures, there was a mean decrease of A$6744 (95% confidence interval, 2430-11,057; P = .002). CONCLUSIONS: The implementation of a preoperative anemia and suboptimal iron stores screening and management clinic in elective colorectal surgery was associated with reductions in red cell transfusions, length of stay, and net costs.

Screening and treating pre-operative anaemia and suboptimal iron stores in elective colorectal surgery: a cost effectiveness analysis.

Our study investigated whether pre-operative screening and treatment for anaemia and suboptimal iron stores in a patient blood management clinic is cost effective. We used outcome data from a retrospective cohort study comparing colorectal surgery patients admitted pre- and post-implementation of a pre-operative screening programme. We applied propensity score weighting techniques with multivariable regression models to adjust for differences in baseline characteristics between groups. Episode-level hospitalisation costs were sourced from the health service clinical costing data system; the economic evaluation was conducted from a Western Australia Health System perspective. The primary outcome measure was the incremental cost per unit of red cell transfusion avoided. We compared 441 patients screened in the pre-operative anaemia programme with 239 patients not screened; of the patients screened, 180 (40.8%) received intravenous iron for anaemia and suboptimal iron stores. The estimated mean cost of screening and treating pre-operative anaemia was AU$332 (£183; US$231; €204) per screened patient. In the propensity score weighted analysis, screened patients were transfused 52% less red cell units when compared with those not screened (rate ratio = 0.48, 95%CI 0.36-0.63, p < 0.001). The mean difference in total screening, treatment and hospitalisation cost between groups was AU$3776 lower in the group screened (£2080; US$2629; €2325) (95%CI AU$1604-5947, p < 0.001). Screening elective patients pre-operatively for anaemia and suboptimal iron stores reduced the number of red cell units transfused. It also resulted in lower total costs than not screening patients, thus demonstrating cost effectiveness.

Improving emergency department blood product use through nursing education.

BACKGROUND: Rapid access to blood products can be lifesaving for hemorrhaging patients, but placing blood components in easily accessible locations in the emergency department (ED) can lead to wasteful patterns of use. Education can lead to improvements in transfusion behavior, but such changes for the better are often short lived. METHODS: To facilitate the early initiation of balanced resuscitation, an emergency blood refrigerator was placed in our ED in February 2015. Physician education to give blood components in a 1:1 plasma:red blood cell (RBC) unit ratio with the plasma given first was given repeatedly with short-term success. Finally, nurses were trained and empowered to strongly suggest that blood components be given in balanced ratios and that plasma be given first. Plasma:RBC unit ratios were compared in successive years with the chi-square test for trend. RESULTS: A total of 1165 RBC units and 623 plasma units were issued from the ED emergency blood refrigerator over 5 years. Intensive physician education is documented at start, in late 2016 to early 2017, and again in early and late 2018. Ratios of components (U plasma/U RBCs) were 2015, 17%; 2016, 26%; 2017, 61%; 2018, 49%; and 2019, 91% (p < 10-18 chi-square for trend). Higher ratios of plasma use were associated with $40,000+ annual savings. CONCLUSIONS: Giving the ED senior nurses formal education about the need for and a policy to give guidance on massive transfusion protocol (MTP) blood component administration sequence has achieved compliance with our MTP's intention. Increasing plasma use reduces group O RBC use and total blood costs.

Cost-effectiveness evaluation of the PROPPR trial transfusion protocols.

BACKGROUND: There have been no prior investigations of the cost effectiveness of transfusion strategies for trauma resuscitation. The Pragmatic, Randomized, Optimal Platelet and Plasma Ratios (PROPPR) study was a Phase III multisite, randomized trial in 680 subjects comparing the efficacy of 1:1:1 transfusion ratios of plasma and platelets to red blood cells with the 1:1:2 ratio. We hypothesized that 1:1:1 transfusion results in an acceptable incremental cost-effectiveness ratio, when estimated using patients' age-specific life expectancy and cost of care during the 30-day PROPPR trial period. STUDY DESIGN AND METHODS: International Classification of Diseases, Ninth Revision codes were prospectively collected, and subjects were matched 1:2 to subjects in the Healthcare Utilization Program State Inpatient Data to estimate cost weights. We used a decision tree analysis, combined with standard costs and estimated years of expected survival to determine the cost effectiveness of the two treatments. RESULTS: The 1:1:1 group had higher overall costs for the blood products but were more likely to achieve hemostasis and decreased hemorrhagic death by 24 hours (p = 0.006). For every 100 patients treated in the 1:1:1 group, eight more achieved hemostasis than in the 1:1:2 group. At 30 days, the total hospital cost per 100 patients was $5.6 million in the 1:1:1 group compared with $5.0 million in the 1:1:2 group. For each 100 patients, the 1:1:1 group had 218.5 more years of life expectancy. This was at a cost of $2994 per year gained. CONCLUSION: The 1:1:1 transfusion ratio in severely injured hemorrhaging trauma patients is a very cost-effective strategy for increasing hemostasis and decreasing trauma deaths.

Fresh Red Cells for Transfusion in Critically Ill Adults: An Economic Evaluation of the Standard Issue Transfusion Versus Fresher Red-Cell Use in Intensive Care (TRANSFUSE) Clinical Trial.

OBJECTIVES: Trials comparing the effects of transfusing RBC units of different storage durations have considered mortality or morbidity as outcomes. We perform the first economic evaluation alongside a full age of blood clinical trial with a large population assessing the impact of RBC storage duration on quality-of-life and costs in critically ill adults. DESIGN: Quality-of-life was measured at 6 months post randomization using the EuroQol 5-dimension 3-level instrument. The economic evaluation considers quality-adjusted life year and cost implications from randomization to 6 months. A generalized linear model was used to estimate incremental costs (2016 U.S. dollars) and quality-adjusted life years, respectively while adjusting for baseline characteristics. SETTING: Fifty-nine ICUs in five countries. PATIENTS: Adults with an anticipated ICU stay of at least 24 hours when the decision had been made to transfuse at least one RBC unit. INTERVENTIONS: Patients were randomized to receive either the freshest or oldest available compatible RBC units (standard practice) in the hospital transfusion service. MEASUREMENTS AND MAIN RESULTS: EuroQol 5-dimension 3-level utility scores were similar at 6 months-0.65 in the short-term and 0.63 in the long-term storage group (difference, 0.02; 95% CI, -0.00 to 0.04; p = 0.10). There were no significant differences in resource use between the two groups apart from 3.0 fewer hospital readmission days (95% CI, -5.3 to -0.8; p = 0.01) during follow-up in the short-term storage group. There were no significant differences in adjusted total costs or quality-adjusted life years between the short- and long-term storage groups (incremental costs, -$2,358; 95% CI, -$5,586 to $711) and incremental quality-adjusted life years: 0.003 quality-adjusted life years (95% CI, -0.003 to 0.008). CONCLUSIONS: Without considering the additional supply cost of implementing a freshest available RBC strategy for critical care patients, there is no evidence to suggest that the policy improves quality-of-life or reduces other costs compared with standard transfusion practice.

The cost of blood: a study of the total cost of red blood cell transfusion in patients with ß-thalassemia using time-driven activity-based costing.

BACKGROUND: To accurately quantify the costs of care for patients with transfusion-dependent thalassemia (TDT), and to evaluate cost-effectiveness of new treatments, data are required on costs of regular red blood cell (RBC) transfusions. However, no previous studies have evaluated the costs of RBC transfusion specifically in chronically transfused patients. METHODS AND MATERIALS: We performed a time-driven activity-based costing (TDABC) study using a health care provider perspective. This was performed over a 1-month period, capturing every step of the transfusion pathway for patients with TDT at a designated provider of specialist thalassemia services in Australia. Detailed process maps were developed to outline treatments and processes directly related to transfusion. For each process map, detailed data collection, including timing of activities, was performed multiple times to account for variation in practice. Costs associated with RBC transfusion were broken down into fixed, process, and RBC procurement costs. RESULTS: The total per-unit cost was US$695.59 (95% confidence interval, US$694.45-US$696.73). Approximately 40% of cost was for procurement of the RBC unit, with process costs accounting for 55%. The single largest contributor to process costs was attributed to iron chelation medication (approximately 80%). In sensitivity analyses, seniority of staff, time to perform processes, and probabilities of different processes occurring did not substantially influence the RBC transfusion cost; however the number of RBC units per transfusion episode did impact the overall cost per RBC unit. CONCLUSIONS: We found significant costs associated with RBC transfusion for TDT, with the product cost contributing less than one-half of the total cost.

The impact of Daratumumab on transfusion service costs.

BACKGROUND: Daratumumab (DARA) is a human IgG1κ monoclonal antibody directed against CD38, approved for the treatment of multiple myeloma. As CD38 is expressed on RBCs, DARA can interfere with pretransfusion testing. DARA interference can be negated by denaturation of CD38 on RBCs with dithiothreitol (DTT) reagents. Because of this interference in pretransfusion testing, our hospital implemented a notification and testing/transfusion algorithm (NATTA) for pretransfusion testing and RBC product provision for DARA patients. This standardized approach combines DTT-based testing with selective genotyping and the provision of phenotypically similar RBCs for patients with clinically significant antibodies. STUDY DESIGN AND METHODS: We evaluated pretransfusion test results and transfusion requirements for 91 DARA patients in an academic medical center over 1 year to determine the incremental cost of pretransfusion testing and RBC selection. The actual costs for the NATTA approach were compared to a theoretical approach using universal genotyping with a provision of phenotypically similar RBC transfusions. RESULTS: The annual cost of testing related to DARA after NATTA implementation was $535.76 per patient. The simulated annual cost for the alternative genotyping with provision of phenotypically similar RBC transfusions approach was $934.83 per patient. CONCLUSION: In our entire cohort of DARA patients, a DTT-based testing algorithm with selective genotyping and provision of phenotypically similar RBCs only for patients with clinically significant antibodies was less expensive than a simulated model of universal genotyping and provision of phenotypically similar RBCs.

Improvements in red blood cell transfusion utilization following implementation of a single-unit default for electronic ordering.

BACKGROUND: The prevention of excessive allogeneic red blood cell (RBC) transfusion is an important component of patient blood management initiatives. In this investigation, changes in transfusion behaviors following modification of computerized physician order entry (CPOE) procedures for RBC transfusions to a single-unit default quantity were assessed. STUDY DESIGN AND METHODS: This is an observational cohort study of adults for whom nonemergency allogeneic RBC transfusions were ordered in the 2 years before and 2 years after the date of modification of the CPOE system to a single-unit default (June 18, 2015). Changes in the frequency of single- versus multiunit RBC transfusion orders and other transfusion metrics were compared between preintervention and postintervention cohorts. RESULTS: A total of 52,773 unique transfusion orders for 61,989 RBC units were included, of which 60,045 (96.9%) were transfused. Single-unit orders increased annually, from 10,404 (74.1%) in the first year to 11,645 (88.6%) in the last year, while multiunit orders decreased by more than half (p < 0.0001). The number of RBC units transfused decreased by 13.9% from 32,528 in the preintervention cohort to 27,497 in the post intervention cohort (p < 0.0001) with an estimated reduction in transfusion-related expenditures of nearly $4 million. The percentage of transfusions associated with a posttransfusion hemoglobin of10 g/dL or greater decreased by 34.5% (p < 0.0001). CONCLUSION: Modification of the CPOE process such that nonemergency RBC transfusion orders were defaulted to a single unit was associated with decreased rates of multiunit RBC transfusion orders, lower transfusion volumes, and substantial cost savings.

Implementation of a patient blood management program in hematopoietic stem cell transplantation (Editorial, p. 2763).

BACKGROUND: Recipients of hematopoietic stem cell transplantation (HSCT) are among the highest consumers of allogeneic red blood cell (RBC) and platelet (PLT) components. The impact of patient blood management (PBM) efforts on HSCT recipients is poorly understood. STUDY DESIGN AND METHODS: This observational study assessed changes in blood product use and patient-centered outcomes before and after implementing a multidisciplinary PBM program for patients undergoing HSCT at a large academic medical center. The pre-PBM cohort was treated from January 1 through September 31, 2013; the post-PBM cohort was treated from January 1 through September 31, 2015. RESULTS: We identified 708 patients; 284 of 352 (80.7%) in the pre-PBM group and 225 of 356 (63.2%) in the post-PBM group received allogeneic RBCs (p < 0.001). Median (interquartile range [IQR]) RBC volumes were higher before PBM than after PBM (3 [2-4] units vs. 2 [1-4] units; p = 0.004). A total of 259 of 284 pre-PBM patients (91.2%) and 57 of 225 (25.3%) post-PBM patients received RBC transfusions when hemoglobin levels were more than 7 g/dL (p < 0.001). The median (IQR) PLT transfusion quantities was 3 (2-5) units for pre-PBM patients and 2 (1-4) units for post-PBM patients (p < 0.001). For patients with PLT counts of more than 10 × 109 /L, a total of 1219 PLT units (73.4%) were transfused before PBM and 691 units (48.8%) were transfused after PBM (p < 0.001). Estimated transfusion expenditures were reduced by $617,152 (18.3%). We noted no differences in clinical outcomes or transfusion-related adverse events. CONCLUSION: Patient blood management implementation for HSCT recipients was associated with marked reductions in allogeneic RBC and PLT transfusions and decreased transfusion-related costs with no detrimental impact on clinical outcomes.

Editor's Choice - A Rotational Thromboelastometry Driven Transfusion Strategy Reduces Allogenic Blood Transfusion During Open Thoraco-abdominal Aortic Aneurysm Repair: A Propensity Score Matched Study.

OBJECTIVE: Open repair of thoraco-abdominal aortic aneurysm (TAAA) is a challenging procedure, associated with high rates of peri-operative bleeding and blood product transfusions. A large intra-operative volume transfusion has been associated with higher in hospital mortality and prolonged mechanical ventilation. A propensity score matched study was carried out to assess whether the introduction of a rotational thromboelastometry (ROTEM) based transfusion strategy reduces allogenic blood transfusion and affects morbidity in patients undergoing open TAAA repair. METHODS: All patients undergoing open TAAA repair at the San Raffaele Scientific Institute between 2009 and 2017 were included. Until 2016, a protocol based on estimated blood loss and conventional coagulation tests was used. After March 2016 a ROTEM guided transfusion protocol was developed and adopted. To account for selection bias, propensity score matching was performed. RESULTS: Five hundred and forty-seven consecutive patients were included. After propensity score matching, 77 patients in the ROTEM algorithm group were successfully matched with 77 patients in the standard algorithm group. Patients managed with ROTEM received fewer red blood cells units (3.5 [range 0-11] vs. 4 [range 0-17]; p = .026) and a lower volume of fresh frozen plasma (286 ± 496 vs. 2,050 ± 1,120; p < .001). In addition, fewer patients received fresh frozen plasma (35% vs. 97%; p < .001). Patients in the ROTEM group showed a significant decrease in the occurrence of pulmonary complications (44% vs. 83%; p = .01). Cost analysis showed a relevant reduction of per-patient expense after the introduction of ROTEM (€834 ± €577 vs. €1,285 ± €851; p < .001) CONCLUSION: A ROTEM guided transfusion strategy significantly limited the quantity of transfused blood products during open TAAA repair, improving clinical outcomes while reducing costs, allowing for better resource distribution in a setting where blood loss is relevant.

The direct labor cost for providing life-saving blood to air medical transport for pre-hospital transfusion.

An IRB approved 2-year review and cost analysis of all packed red blood cells (pRBCs) issued, transfused and returned to the blood bank by air medical transport services for pre-hospital transfusion was performed. The cost to the blood bank for issuing and returning pRBCs that were not transfused in the pre-hospital setting was $3.24 per unit. Over the study period, there were 334 pRBCs not transfused by air medical services and returned to the blood bank totaling $1082.16 in direct labor costs, a trivial amount for providing possibly life-saving blood for pre-hospital transfusion.

A time-driven, activity-based costing methodology for determining the costs of red blood cell transfusion in patients with beta thalassaemia major.

OBJECTIVES: To describe the methodology to estimate the total cost of administration of a single unit of red blood cells (RBC) in adults with beta thalassaemia major in an Australian specialist haemoglobinopathy centre. BACKGROUND: Beta thalassaemia major is a genetic disorder of haemoglobin associated with multiple end-organ complications and typically requiring lifelong RBC transfusion therapy. New therapeutic agents are becoming available based on advances in understanding of the disorder and its consequences. Assessment of the true total cost of transfusion, incorporating both product and activity costs, is required in order to evaluate the benefits and costs of these new therapies. METHODS: We describe the bottom-up, time-driven, activity-based costing methodology used to develop process maps to provide a step-by-step outline of the entire transfusion pathway. Detailed flowcharts for each process are described. Direct observations and timing of the process maps document all activities, resources, staff, equipment and consumables in detail. The analysis will include costs associated with performing these processes, including resources and consumables. Sensitivity analyses will be performed to determine the impact of different staffing levels, timings and probabilities associated with performing different tasks. RESULTS: Thirty-one process maps have been developed, with over 600 individual activities requiring multiple timings. These will be used for future detailed cost analyses. CONCLUSIONS: Detailed process maps using bottom-up, time-driven, activity-based costing for determining the cost of RBC transfusion in thalassaemia major have been developed. These could be adapted for wider use to understand and compare the costs and complexities of transfusion in other settings.

Impact of a Patient Blood Management monitoring and feedback programme on allogeneic blood transfusions and related costs.

A Patient Blood Management programme was established at the University Hospital of Zurich, along with a monitoring and feedback programme, at the beginning of 2014 with a first analysis reported in 2015. Our study aimed to investigate the further impact of this Patient Blood Management monitoring and feedback programme on transfusion requirements and related costs. We included adult patients discharged between 2012 and 2017. A total of 213,882 patients underwent analysis: 66,659 patients in the baseline period (2012-2013); 35,309 patients in the year after the introduction of the Patient Blood Management monitoring and feedback programme (2014) and 111,914 patients in the continued sustainability period (2015-2017). The introduction of the Patient Blood Management monitoring and feedback programme reduced allogeneic blood product transfusions by 35%, from 825 units per 1000 hospital discharges in 2012 to 536 units in 2017. The most sustained effect was an approximately 40% reduction in red blood cell transfusions, from 535 per 1000 discharges to 319 units. Fewer patients were transfused in the periods after the introduction of the Patient Blood Management monitoring and feedback programme (6251 (9.4%) vs. 2932 (8.3%) vs. 8196 (7.3%); p < 0.001). Compared with 2012, the yearly OR for being exposed to any blood transfusion declined steadily after the introduction of the Patient Blood Management monitoring and feedback programme to 0.64 (95%CI 0.61-0.68; p < 0.001) in 2017. For patients requiring extracorporeal membrane oxygenation, transfusion requirements were also sustainably reduced. This reduction in allogeneic blood transfusions led to savings of 12,713,754 Swiss francs (£ 9,497,000 sterling; EUR 11,100,000; US$ 12,440,000) in blood product acquisition costs over 4 years. In-hospital mortality was not affected by the programme. The Patient Blood Management monitoring and feedback programme sustainably reduced transfusion requirements and related costs, without affecting in-hospital mortality.

Analysis of red blood cell use in elective surgeries over 12 years in Korea.

BACKGROUND: Red blood cell (RBC) transfusion is a lifesaving process for patients with perioperative bleeding, but transfusion can cause adverse events. Effective utilization and management of blood products as a limited resource is essential when considering cost-efficiency and patient safety. STUDY DESIGN AND METHODS: We analyzed the number of RBC units used during the hospitalization of patients who had undergone surgical procedures from 2002 to 2013 using National Health Insurance Service-National Sample Cohort data, which include a total of 487,238 cases for 206 selected operations. RESULTS: RBC units were used in 39,637 (8.1%) cases. A total of 60,815 RBC units were transfused with a mean of 0.13 units per patient overall and a mean of 1.53 units per case receiving RBC transfusion. In addition, 56.7% of the RBC units were transfused for females, and 60.1% of RBC units were transfused into patients aged 60 or older. RBC units were used most often in orthopedic surgeries (33.8%), followed by general surgeries (12.0%) and vascular surgeries (11.8%). The number of operations performed in the cohort increased from 27,690 in 2002 to 49,473 in 2013, and the mean number of RBC units used per operation also increased from 0.08 units in 2002 to 0.15 units in 2013. CONCLUSION: Continuous management for blood preparation and transfusion is needed for efficient utilization of blood. Periodic investigation on the use of blood products through nationwide studies could suggest data applicable to blood product preparation for various elective surgical operations.

Automated RBC exchange compared to manual exchange transfusion for children with sickle cell disease is cost-effective and reduces iron overload.

BACKGROUND: Chronic transfusion in sickle cell disease (SCD) remains the gold standard therapy for stroke prevention and for patients with severe disease despite adequate hydroxyurea treatment. The aim of our study was to assess the safety and efficacy of automated red blood cell exchange (aRBX) in patients with SCD previously treated with manual exchange transfusion (MET). Costs related to transfusion and chelation overtime were evaluated. STUDY DESIGN AND METHODS: Beginning in January 2012, children with SCD who weighed 30 kg or more on MET could switch to aRBX. Clinical, biological, and procedures' data, including costs, were recorded for the last 6 months on MET and compared to those after the first and the second year on aRBX. RESULTS: Ten patients switched from MET to aRBX at a median age of 11.8 years. After the switch, median hemoglobin S (HbS) increased significantly (33.5% on MET compared to 45% on aRBX; p < 0.001) but remained in the target values for all patients. Median ferritin decreased significantly (663.3 µg/L on MET compared to 126.8 µg/L on aRBX; p < 0.001) and intervals between procedures were significantly longer. The requirements of red blood cells (RBCs)/kg/year were not different on MET (0.88 unit/kg/year) than during the second year on aRBX (1.07 unit/kg/year; p = NS). MET costs were similar compared to aRBX since chelation was stopped in previously treated patients. CONCLUSION: Erythrocytapheresis reduces iron overload and allows a longer interval between procedures without a higher RBC requirement from the second year on aRBX. The cost did not increase as estimated in our Belgian Health Care System.

Incidence and cost of perioperative red blood cell transfusion for elective spine fusion in a high-volume center for spine surgery.

BACKGROUND: Spine fusion is a surgical procedure characterized by a significant perioperative bleeding, which often requires red blood cell (RBC) transfusion. METHODS: The incidence and the cost of RBC transfusion were evaluated in all patients undergoing elective surgery for spine fusion in our Institution, a high-volume center for spine surgery, over a period of 3 years. The analysis specifically addressed the RBC transfusion need in all the different spine fusion procedures (atlanto-axial, cervical, dorsal, lumbar, revisions) with the different surgical approaches (anterior, posterior). RESULTS: During the 3 years of observation, a total of 1.882 elective spine fusions were performed. More than half of the procedures (n = 964) were posterior lumbar fusions. Overall, 5% of the patients (n = 103) required RBC transfusion. The cervical fusions were the procedures with the lowest percentage of RBC need (0-5%), while the dorsal and the lumbar ones, with the anterior approach, represented the procedures with the highest rate of transfusion (29% and 25% respectively). More than 60 % of the RBC units were employed in the instance of posterior lumbar fusion, while a variable 1-10% of the units was used in each of the other procedures. The overall transfusion cost was of 46.000 euros, with a distribution of costs that paralleled the amount of units transfused for each procedure. CONCLUSIONS: Several surgical and patient factors may contribute to the perioperative blood loss. An accurate patient blood management, may efficiently decrease transfusion requirements and ultimately healthcare costs.

Red blood cell transfusion probability and associated costs in neurosurgical procedures.

BACKGROUND: The extent of red blood cell units (RBC) needed for different neurosurgical procedures and the time point of their administration are widely unknown, which results in generously cross-matching prior to surgery. However, RBC are increasingly requested in the aging western populations, and blood donations are significantly reduced. Therefore, the knowledge of the extent and time point of administration of RBC is of major importance. METHODS: This is a retrospective single center analysis. The incidence of RBC transfusion during surgery or within 48 h after surgery was analyzed for all neurosurgical patients within 3 years. Costs for cross-matched and transfused RBC were calculated and risk factors for RBC transfusion analyzed. RESULTS: The risk of intraoperative RBC administration was low for spinal and intracranial tumor resections (1.87%) and exceeded 10% only in spinal fusion procedures. This was dependent on the number of fused segments with an intraoperative transfusion risk of > 12.5% with fusion of more than three levels. Multiple logistic regression analysis showed a significantly increased risk for RBC transfusion for female gender (p = 0.006; OR 1.655), higher age (N = 4812; p < 0.0001; OR 1.028), and number of fused segments (N = 737; p < 0.0001; OR 1.433). Annual costs for cross-matching were 783,820.88 USD and for intraoperative RBC administration 121,322.13 USD. CONCLUSIONS: Neurosurgical procedures are associated with a low number of RBC needed intraoperatively. Only elective spine fusion procedures with ≥ 3 levels involved and AVM resections seem to require cross-matching of RBC. The present data may allow changing the preoperative algorithm of RBC cross-matching in neurosurgical procedures and help to save resources and costs.

Is treatment of geriatric hip fracture patients cost-covering? Results of a prospective study conducted at a German University Hospital.

INTRODUCTION: Hip fractures have increased medical and socio-economic importance due to demographic transition. Information concerning direct treatment costs and their reimbursement in Germany is lacking. MATERIALS AND METHODS: Four hundred two hip fracture patients older than 60 years of age were observed prospectively at a German University Hospital. Treatment costs were determined with up to 196 cost factors and compared to the reimbursement. Finally, statistical analysis was performed to identify clinical parameters influencing the cost-reimbursement relation. RESULTS: Treatment costs were 8853 € (95% CI 8297-9410 €), while reimbursement was 8196 € (95% CI 7707-8772 €), resulting in a deficit of 657 € (95% CI 143-1117 €). Bivariate analysis showed that the cost-reimbursement relation was negatively influenced mainly by higher age, higher ASA score, readmission to the intensive care unit (ICU) and red blood cell transfusion. Adjusted for other parameters, readmission to the ICU was a significant negative predictor (- 2669 €; 95% CI - 4070 to - 1268 €; p < 0.001), while age of 60-75 years was a positive predictor for the cost-reimbursement relation (1373 €; 95% CI 265-2480 €; p = 0.015). CONCLUSIONS: Treatment of geriatric hip fracture patients in a university hospital in Germany does not seem to be cost-covering. Adjustment of the reimbursement for treatment of complex hip fracture patients should be considered.

Impact of red blood cell transfusion strategies in haemato-oncological patients: a systematic review and meta-analysis.

Haemato-oncological patients receive many red blood cell (RBC) transfusions, however evidence-based guidelines are lacking. Our aim is to quantify the effect of restrictive and liberal RBC transfusion strategies on clinical outcomes and blood use in haemato-oncological patients. A literature search, last updated on 11 August 2016, was performed in PubMed, EMBASE (Excerpta Medica Database), Web of Science, Cochrane, CINAHL (Cumulative Index to Nursing and Allied Health Literature) and Academic Search Premier without restrictions on language and year of publication. Randomized controlled trials and observational studies that compared different RBC transfusion strategies in haemato-oncological patients were eligible for inclusion. Risk of bias assessment according to the Cochrane collaboration's tool and Newcastle-Ottawa scale was performed. After removing duplicates, 1142 publications were identified. Eventually, 15 studies were included, reporting on 2636 patients. The pooled relative risk for mortality was 0·68 [95% confidence interval (CI) 0·46-1·01] in favour of the restrictive strategy. The mean RBC use was reduced with 1·40 units (95% CI 0·70-2·09) per transfused patient per therapy cycle in the restrictive strategy group. There were no differences in safety outcomes. All currently available evidence suggests that restrictive strategies do not have a negative impact regarding clinical outcomes in haemato-oncological patients, while it reduces RBC use and associated costs.
