Background Results The incidences of blood transfusion are low for the age groups Females aged years seem to have higher incidence of blood use than males of corresponding ages. This This study describes the incidence of In the years between , an average of 4,455 relation is reversed from the year group and up, where individual patients received RBC every year. These patients transfusion of red blood cells (RBC) in the males have a higher incidence of blood transfusion. used an average of 25,400 units per year, thus requiring an general population. average of 5.7 units RBC. The authors used The incidence of receiving a blood transfusion during a calendar year is 0.94 percent for the total population of demographic data and Funen (472,349 citizens in 2006). This is an average for the information from the local ten year period, with individual years ranging from 0.87 blood transfusion register 0.99 percent. and diagnosis and Sub grouping according to sex and ten year age groups procedure register in the yields information about incidence of blood transfusion: Danish county of Funen for Incidence of transfusion the years its fu The total number of RBC units used was also studied. The following charts display blood product use by the different age groups for different years. Most blood is used by men aged Blood use by female group Blood use by male group Epidemiology of Blood Transfusion in a Danish County (AABB 2008) The incidence of receiving a blood transfusion during a calendar year is 0.94 percent for the total population of Funen (472,349 citizens in 2006). Methods All transfusion data in the county of Funen has been stored electronically since All sets of transfusion data include the recipient s personal identification number (PIN), which is used for all contacts with public service, including the public health service. Only blood recipients that were citizens of the county of Funen were included in the study. For each year since 1997 we have found the incidence ( risk ) of blood transfusion during the calendar year for different age groups for both sexes. We have calculated the incidence of RBC transfusions for ten year age groups, by finding the number of unique patients transfused each year, and dividing by the total number of citizens in the corresponding age- and gender groups. Percent years Male Female Age group Incidence of blood transfusion to unique patients in one year. Average Incidence of transfusion is below 0.32 % for citizens 0-39 years old. The incidence increases from 0.35 % in male and 0.44% in female year groups, to 9.34 % and 8.17 % in the 90+ year groups. Conclusions This study shows the incidence of blood transfusion for the general population in a county. As expected, the incidence of RBC transfusions increases with age. Until the age of 19, incidence is nearly identical for males and females (few patients actually transfused). In the age groups years, the incidence is highest for females, whereas males have the highest incidence in the age groups We have shown the average incidence of receiving a RBC unit during a calendar year in the county of Funen to be 0.94 percent.

4 Transfusion Requirements in Critical Care (TRICC) Variation and overconsumption Does it matter? N Engl J Med 1999; 340(6): Transfusion requirements in critical care A multicenter, RANDOMIZED, CONTROLLED clinical trial of transfusion requirements in critical care Liberal strategy: 420 patients: transfusions were given when the hemoglobin concentration fell below 10.0 g/dl and hemoglobin conc. were maintained at g/dl Restrictive strategy: 418 patients: transfusions were given when the hemoglobin concentration fell below 7.0 g/dl and hemoglobin conc. were maintained at 7.0 to 9.0 g/dl Transfusion requirements in critical care Results The restrictive strategy decreased the average number of red-cell units transfused by 54 percent and decreased exposure to any red cells after randomization by 33 percent. Transfusion requirements in critical care Transfusion requirements in critical care Results Overall, 30-day mortality was similar in the two groups (18.7 percent vs percent, P= 0.11) The rates were significantly lower with the restrictive transfusion strategy among patients who were: less acutely ill (restrictive 8.7% and liberal 16.1%; P=0.03) less than 55 years of age (restrictive 5.7% and liberal 13.0%; P=0.02) but NOT among patients with clinically significant cardiac disease (20.5% and 22.9%, respectively; P=0.69). 4

5 Transfusion Trigger Trial for Functional Outcomes in Cardiovascular Patients Undergoing Surgical Hip Fracture Repair (FOCUS) Transfusion Strategies for Acute Upper Gastrointestinal Bleeding A liberal transfusion strategy (N = 1007, a hemoglobin threshold of 10 g/dl), as compared with a restrictive strategy, (N = 1009, symptoms of anemia or at physician discretion for a hemoglobin level of <8 g /dl) did not reduce rates of death or inability to walk independently on 60-day follow-up or reduce in-hospital morbidity in elderly patients at high cardiovascular risk. Transfusion Strategies for Acute Upper Gastrointestinal Bleeding Transfusion Strategies for Acute Upper Gastrointestinal Bleeding Liberal strategi: 460 patienter randomiseret til liberal strategi: RBC-transfusioner når hæmoglobin-koncentrationen (Hgb) falder under 5,6 mmol/l (9 g/dl) Hgb holdes mellem 5,6 og 6,8 mmol/l ( g/dl) Restriktiv strategi: 461 patienter randomiseret til restriktiv strategi: RBC-transfusioner når hæmoglobin-koncentrationen (Hgb) falder under 4,3 mmol/l (7.0 g/dl) Hgb holdes mellem 4,3 og 5,6 mmol/l (7-9 g/dl) KET 2013 Quality of life (QoL) measurement was measured preoperatively and twice up to 14 days postoperatively using the Functional Status Index (FSI), the Visual Analogue Score (VAS)-Fatigue score, and the Functional Assessment of Cancer Therapy Anemia (FACT-Anemia) subscale RESULTS: A total of 603 patients were evaluated. All patients scored worse postoperatively, but none of the scores correlated with Hb values, neither after correcting for confounding factors. Even more, the changes between preoperative and postoperative Hb levels were not correlated with changes in fatigue scores. CONCLUSION: In hip and knee prosthesis surgery no correlation existed between postoperative Hb levels or acute postoperative decline in Hb values and Quality of life scores 5

Transfusions should NOT be given if hemoglobin concentration is above 9.7 g/dl (6.0 mmol/l ). We concluded that guidelines were certainly not followed, if patients hemoglobin concentration were 10.5 g/dl (6.5 mmol/l) or higher. mmol/l 10.5 g/dl 39% OK (?) 61% NOT OK 8

Den videre behandling af kontrollabel blødning omfatter RBC,FFP and platelets by the 6 12 principle. Ved pågående blødning hos voksne, dvs. vedvarende transfusionsbehov hos voksne, behandles efter eksempelvis seks erytrocyttransfusioner med: 6 RBC, then FFP and RBC 1:1 Sundhedsstyrelsen: Vejledning om blodtransfusion

Krystalloider anvendes kortvarigt i ventetiden på balanceret blodkomponentbehandling ækvivalent til fuldblod. Der skal straks skiftes til balanceret blodkomponentterapi, hvis en kontrollabel blødning udvikler sig og bliver ukontrollabel.
