1 Introduction of a Single Unit Transfusion Policy Patient Blood Management Pilot 2014

2 Introduction Patient Blood Management The Safety of Blood – SHOT data Single unit blood transfusion policy Causes of anaemia Alternatives to blood Case studies

3 Changing Transfusion Practice Patient Blood Management (PBM) is a National and International initiative in Blood Transfusion To give blood transfusions appropriately and effectively on an individual patient basis

4 Blood safety SHOT Report 2013 22 deaths –Avoidable, delayed or undertransfused (5) –Transfusion-related Acute Lung Injury (1) –Post Transfusion Purpura (1) –Haemolytic Transfusion Reaction (1) –Transfusion-associated circulatory overload (12) –Incorrect Blood Component Transfused (1) –Unclassified complication of transfusion (1) Annual SHOT Report 2013

5 Blood safety 143 Major Morbidity –Acute transfusion reactions (76) –Transfusion-associated circulatory overload (34) –Incorrect blood component transfused (6) –Haemolytic transfusion reactions (8) –Transfusion-related acute lung injury (9) –Anti-D errors (1) –Transfusion-transmitted infections (0) –Avoidable, delayed or undertransfusion (7) –Unclassifiable complications of transfusion (1) –Transfusion-associated dyspnoea (1) Annual SHOT Report 2013

6 TACO The International Society of Blood Transfusion (ISBT) definition states that TACO includes any 4 of the following that occur within 6 hours of transfusion –Acute respiratory distress –Tachycardia –Increased blood pressure –Acute or worsening pulmonary oedema –Evidence of positive fluid balance Annual SHOT Report 201

7 TACO - Case Study 78 year old female, weight 63.3kg Admitted to Emergency Department unwell and feeling faint Vial signs normal Hb 59g/L, microcytic blood picture – likely iron deficiency 2 units RBC ordered by ED doctor First unit commenced at 14:12 Patient transferred to acute medical unit

8 TACO - Case Study During ward round an additional 2 units RBC prescribed After 270ml of 4 th unit patient developed massive pulmonary oedema and left ventricular failure Baseline obs – pulse 98, BP 120/75mmHg Reaction obs – pulse 82, BP 152/111mmHg Admitted to ITU and received CPAP and furosemide Patient died Annual SHOT Report 2013

9 Calculating dose Transfusing a volume of 4ml/kg will typically give a Hb rise of 10g/L and should only be applied as an approximation for a 70-80kg non- bleeding patient Annual SHOT report 2012. British Committee for Standards in Haematology: Addendum to Administration of Blood Components. 2012.

10 Calculating dose National Comparative Audit of Blood Transfusion - 2011 Audit of the use of blood in adult medical patients, part 2 Correlation between body weight and Hb increment

11 Errors in Transfusion Annual SHOT Report 2013

12 Single Unit Transfusions For stable non-bleeding patients Investigate causes of anaemia – Iron, B12, folate investigations Only transfuse if the patient is symptomatic Transfuse a single unit and reassess the patient for symptoms of anaemia (Hb) Only transfuse second unit if patient symptomatic

13 National Audit National Comparative Audit for Blood Transfusion of Medical Use of Blood Red cells transfused; 65% were 2 units, 15% were 3 units and 6% were 4 units Transfusion in cases with possible reversible anaemia (20%) Transfusion above the Hb threshold defined by the audit algorithm (29%) Over-transfusion (33%) Transfusion to more than 20g/L above threshold

From: Outcomes Using Lower vs Higher Hemoglobin Thresholds for Red Blood Cell Transfusion JAMA. 2013;309(1):83-84. doi:10.1001/jama.2012.50429 30-Day mortality was evaluated in 4975 patients included in 11 of 19 trials. Adapted from Analysis 3.2 in Carson JL, Carless PA, Hebert PC. Transfusion thresholds and other strategies for guiding allogeneic red blood cell transfusion.

15 Evidence Multicentre randomised controlled trials demonstrate that a restrictive approach to RBC transfusion decreases transfusions without increasing mortality or adverse events (Herbert et al 1999, Carson et al 2011, Villanueva 2013) Single unit policy reduces the number of transfusions and therefore reduces the risk to the patient (Berger et al 2012)

16 Evidence WA PBM program introduced in a tertiary hospital in 2008; 26% reduction in RBC transfusions and 16% reduction in PLT transfusions over three years (Leahy 2013) ReferenceFindings implementing restrictive/single unit policy Yerrabothala et al (2014) The total number of red blood cells transfused/1000 patient days decreased from 60.8 to 44.2 and the proportion of 2-unit transfusions decreased from 47% to 15% Berger et al (2012) Reduced red cell usage by 25% with no evidence of more severe bleeding or reduction in survival in patients receiving intensive chemotherapy or stem cell transplantation. Royal Oldham Hospital, UK (HTC verbal report, 2014) Indicates a reduction in red cell usage of 10.4% last quarter (2.5% last year) and platelet usage by 16.8%

17 Causes of anaemia Why is your patient anaemic? –Iron Deficiency –B12 Deficiency –Folate Deficiency Test for these before transfusion

18 Blood results Royal College of Pathologists of Australia - Common sense pathology 2004

19 Alternatives to Blood Ferrous sulphate supplements IV Iron B12 injections Folate supplementation

20 Triggers Table from Handbook of Transfusion Medicine 4 th Edition

21 Indications for Transfusion National Blood Transfusion Committee - Indication codes for Transfusion Symptomatic Anaemia Fatigue Breathless at rest Chest pains/Palpitations Faint

22 Patient Assessment

23 Consent for Transfusion SaBTO - 2011 Valid consent for blood transfusion should be obtained and documented in the patient's clinical record by the healthcare professional There should be a standardised information resource for clinicians indicating the key issues to be discussed by the healthcare professional when obtaining valid consent from a patient for a blood transfusion

24 Single Unit Project Audit Education Prospective collection of data Regular review Feedback Multidisciplinary team

25 Case Study 1 Female, 83 Admitted to Marjory Warren with new diagnosis of PE Background of LRTI Long smoking history Aiming for sats of 85-92% on room air
