Improving Awareness about Patient Blood Management in Portugal: A Call for Action Arising from a Delphi Panel

Anaemia and iron deficiency are associated with increased mortality and poor surgical outcomes. Consensus in their definitions is expected to optimize their management, which is encompassed by patient blood management, providing patient-centred care while improving patient safety and clinical outcomes. Patient blood management implementation is even more relevant in contingency times and faces barriers due to lack of standardization, among others. The aim is to establish a consensus on these diagnoses and implement patient blood management principles in clinical practice in Portugal.

Eight experts in Transfusion Medicine, Haematology, Anaesthesiology, Internal Medicine, and Obstetrics/Gynaecology were assembled; a focus group was conducted, defining 33 statements. A Delphi panel was conducted, with experts from the clinical specialities named above as well as from General Surgery, Urology, and Orthopaedics.

The Delphi panel's rounds had 70 (Round 1) and 46 (Round 2) respondents. Specialists were consensual in only two statements, on the existence of a preoperative patient blood management consultation for candidates to elective surgeries in which the use of blood derivatives is anticipated and, on the importance of the correction of postoperative anaemia and iron deficiency. Of the remaining 31 statements, 27 reached high agreement or disagreement by the respondents.

Consensus was reached in only two (6%) of the 33 statements. There was a consensual agreement on the relevance of establishing patient blood management as the standard of care and of valuing preoperative and postoperative patient blood management interventions. Nevertheless, our results point to the lack of awareness regarding patient blood management principles - which could result in better postoperative outcomes, shorter hospitalizations, reduced costs and increased availability of beds. Training and literacy initiatives could help further implement patient blood management standards in Portuguese hospitals.
