Patient blood management – recommendations from the International Consensus Conference, Frankfurt/Main, Germany

An International Consensus Conference (ICC) on PBM was held in 2018 to develop evidence‐based clinical and research recommendations for preoperative anaemia, red blood cell (RBC) transfusion thresholds for adults and implementation of PBM programmes. An international scientific committee (SC) defined 17 Population‐Intervention‐Comparison‐Outcome (PICO) questions for the three topics preoperative anaemia, red blood cell (RBC) transfusion thresholds for adults and PBM implementation. Based on these questions, an extensive literature search was conducted in four biomedical databases. The GRADE framework (= grading of recommendations, assessment, development and evaluation) was used to develop a systematic approach to the presentation of evidence summaries and for making clinical recommendations. Three expert panels (EP) consisting of clinicians, scientists, nurses, patient representatives and methodologists were established and used these methods to develop recommendations driven by published evidence. Out of more than 17 500 literature citations, data from 145 studies were incorporated. The expert panel for preoperative anaemia developed 4 clinical and 3 research recommendations. A strong recommendation advices early detection and management of preoperative anaemia before major elective surgery. For RBC transfusion thresholds, 4 clinical and 6 research recommendations have been formulated. Two strong clinical recommendations for RBC transfusion thresholds comprise a haemoglobin concentration of <7 g/dl for critically ill, but clinical stable adult intensive care patients independent of septic shock and <7·5 g/dl for adults undergoing cardiac surgery. For the implementation of PBM programmes, 2 clinical and 3 research recommendations were developed. Research recommendations were formulated as encouragement of new studies to answer open questions. Due to the relative paucity of strong evidence‐based answers in current publications to the 17 PICO questions, additional research, an international consensus for accepted definitions and Hb thresholds as well as clinically meaningful end‐points for clinical studies are necessary. The 2018 PBM ICC defined the current status of PBM evidence and established 10 clinical and 12 research recommendations for preoperative anaemia, RBC transfusion thresholds for adults and implementation of PBM programmes.
