  1. Blood transfusion at STH Phil Dobson Consultant Anaesthetist Chair of the Hospital Transfusion Committee

  2. Objectives National and local guidelines National and local transfusion data New initiatives

  3. Concerns: Patient safety: errors, vCJD Demand for blood and shortages Wide variation in practice National “ Better Blood Transfusion” initiative 1998, 2002, 2007

  4. Patient Blood Management; Safe transfusion – right blood, right patient, right time and right place • Avoid unnecessary and inappropriate transfusions. •‘Wrong blood into patient’ incidents are nearly always caused by human error •At every stage of the blood administration process the key elements are positive patient identification, excellent communication and good documentation. These can be enhanced by the use of electronic transfusion management systems •Where possible, patients should give ‘valid consent’ for transfusion based on appropriate information and discussion, but signed consent is not a legal requirement. •‘Out of hours’ requests for transfusion and overnight administration of blood should be avoided wherever possible because of an increased risk of errors.

  5. UK Transfusion Statistics • In 2011: NHSBT issued 1.8 million red cells NHSBT issued 260,000 platelets NHSBT issued 248,000 FFP NHSBT issued 123,000 cryo

  6. Where are we now? Nationally audits show: 15-20% red cells are used inappropriately 30% of platelets/plasma are used inappropriately Variability in uptake on the use of alternatives to transfusion Difficulty accessing medical education and training Lack of patient involvement

  7. N = National %. Numbers represent individual sites 67% 66% 22% 22%

  8. Nice guidance 2015 www.nice.org.uk/guidance/ng24

  9. Red blood cells 2,000,000 20,000 121 70 1.8%

  10. 1.2 Red blood cells Thresholds and targets 1.2.1 Use restrictive red blood cell transfusion thresholds for patients who need red blood cell transfusions and who do not: have major haemorrhage or have acute coronary syndrome 1.2.2 When using a restrictive red blood cell transfusion threshold, consider a threshold of 70 g/litre and a haemoglobin concentration target of 70–90 g/litre after transfusion. 1.2.3 Consider a red blood cell transfusion threshold of 80 g/litre and a haemoglobin concentration target of 80–100 g/litreafter transfusion for patients with acute coronary syndrome. Doses 1.2.5 Consider single‑unit red blood cell transfusions for adults who do not have active bleeding. 1.2.6 After each single‑unit red blood cell transfusion, clinically reassess and check haemoglobin levels

  11. Platelets 193 5000 3.6%

  12. 1.3 Platelets Patients with thrombocytopenia who are bleeding 1.3.1 Offer platelet transfusions to patients with thrombocytopenia who have clinically significant bleeding and a platelet count below 30×109 per litre. 1.3.2 Use higher platelet thresholds(up to a maximum of 100×109 per litre) for patients with thrombocytopenia and either of the following: severe bleeding (WHO grades 3 and 4) bleeding in critical sites, such as the central nervous system (including eyes). Patients who are having invasive procedures or surgery 1.3.4 above 50×109 per litre in patients who are having invasive procedures or surgery. 1.3.5 50–75×109 per litre for patients with a high risk of bleeding who are having invasive procedures or surgery 1.3.6 above 100×109 per litre in patients having surgery in critical sites, such as the central nervous system Doses 1.3.9 Do not routinely transfuse more than a single dose of platelets. 1.3.10 Only consider giving more than a single dose of platelets in a transfusion for patients with severe thrombocytopenia and bleeding in a critical site, such as the central nervous system

  13. BCSH Platelet Guidelines 2003 • Threshold of 10 x 10^9/L is safe • 50 x 10^9/L for lumber puncture, epidural, gastroscopy, central line insertion, bronchial biopsy, liver biopsy, laparotomy • 100 x 10^9/L for brain and eye operation • 50 x 10^9/L for acute DIC • 50 x 10^9/L for massive transfusion • 100 x 10^9/L for massive transfusion and multiple trauma

  14. FFP/Cryoprecipitate 5 days 28 1.5 20-30%

  15. 1.4 Fresh frozen plasma Thresholds and targets 1.4.1 Only consider fresh frozen plasma transfusion for patients with clinically significant bleeding but without major haemorrhage if they have abnormal coagulation test results (for example, prothrombin time ratio or activated partial thromboplastin time ratio above 1.5). 1.4.2 Do not offer fresh frozen plasma transfusions to correct abnormal coagulation in patients who: are not bleeding (unless they are having invasive procedures or surgery) need reversal of a vitamin K antagonist. Doses 1.4.4 Reassess the patient's clinical condition and repeat the coagulation tests after fresh frozen plasma transfusion to ensure that they are getting an adequate dose

  16. 1.5 Cryoprecipitate Thresholds and targets 1.5.1 Consider cryoprecipitate transfusions for patients without major haemorrhage who have: clinically significant bleeding anda fibrinogen level below 1.5 g/litre. 1.5.3 Consider prophylactic cryoprecipitate transfusions for patients with a fibrinogen level below 1.0 g/litre who are having invasive procedures or surgery with a risk of clinically significant bleeding. Doses 1.5.4 Use an adult dose of 2 pools when giving cryoprecipitate transfusions

  17. Blood component usage at STH

  18. STH Blood Usage: Red Cells

  19. STH Blood Usage: Platelets

  20. STH Blood Usage: Plasma

  21. Blood product wastage at STH

  22. Alternatives to blood products Treat pre-operative anaemia! • >30% patients presenting for elective surgery • Anaemia is an independent risk factor for poor outcome • Blood transfusion does not ameliorate this risk • Pre-operative anaemiamust be investigated and managed pre-op

  23. 1.1 Alternatives to blood transfusion Erythropoietin 1.1.1 The patient has anaemia and meets the criteria for blood transfusion, but declines it because of religious beliefs or other reasons or the appropriate blood type is not available because of the patient's red cell antibodies Intravenous and oral iron 1.1.2 Offer oral iron before and after surgery to patients with iron‑deficiency anaemia. 1.1.3 Consider intravenous iron before or after surgery for patients who: have iron‑deficiency anaemia and cannot tolerate or absorb oral iron are diagnosed with functional iron deficiency

  24. Cell salvage and tranexamicacid 1.1.5 Offer tranexamic acid to adults undergoing surgery who are expected to have at least moderate blood loss (greater than 500 ml). 1.1.7 Do not routinely use cell salvage without tranexamic acid. 1.1.8 Consider intra‑operative cell salvage with tranexamic acid for patients who are expected to lose a very high volume of blood (for example in cardiac and complex vascular surgery, major obstetric procedures, and pelvic reconstruction and scoliosis surgery).

  25. Autologous blood transfusion •Predeposit autologous blood donation before surgery is of uncertain benefit •Intraoperative cell salvage (ICS) is effective (and may be life-saving) in elective or emergency high blood loss surgery and management of major haemorrhage •Postoperative cell salvage (PCS) and reinfusion can reduce blood use in joint replacement and scoliosis surgery. •ICS and PCS are usually acceptable to Jehovah’s Witnesses.

  26. 1.7 Patient safety Monitor for acute blood transfusion reactions (!) Electronic patient identification systems 1.7.3 Consider using a system that electronically identifies patients to improve the safety and efficiency of the blood transfusion process.

  27. UK Deaths following Transfusion 2013 • Delayed transfusion (5) • TRALI (1) • Post transfusion purpura (1) • Haemolytic transfusion reaction (1) • Transfusion associated circulatory overload (12) • Incorrect blood component transfused (1) • Unclassified (1) • Total (22)

  28. Transfusion incidents at STH 2ndquarter 2016 10 externally reported All considered low risk when evaluated – did not harm patients; 2 WBIT 3 blood component stored in ward fridge WBIT ongoing issue, not improving Emergency care/ Obs,gynae,neonates/ surgical specialties highest incidence

  29. 1.8 Patient information 1.8.1 Provide verbal and written information to patients who may have or who have had a transfusion, and their family members or carers, explaining: the reason for the transfusion the risks and benefits any alternatives that are available, and how they might reduce their need for a transfusion that they are no longer eligible to donate blood that they are encouraged to ask questions 1.8.2 Document discussions in the patient's notes 1.8.3 Provide the patient and their GP with copies of the discharge summary or other written communication that explains: the details of any transfusions they had the reasons for the transfusion any adverse events that they are no longer eligible to donate blood
