Guidelines on the use of irradiated blood components prepared by the British Committee for Standards in Haematology blood transfusion task force

Abstract

Search terms included: Transfusion-associated graft-versus-host disease, Transfusion-associated graft-versus-host, TA-GvHD. The last guideline covering this topic was published in 1996 (British Committee for Standards in Haematology (BCSH) Blood Transfusion Task Force, 1996. The writing group produced the new draft guideline, which was subsequently revised by consensus by members of the Haemato-oncology and Blood Transfusion Task Forces of the BCSH. The guideline was then reviewed by a sounding board of approximately 100 UK haematologists, the BCSH and the committee of the British Society for Haematology and amended, again by consensus. Criteria used to quote levels and grades of evidence are according to the GRADE system (Guyatt et al, 2006). Strong recommendations (grade 1, ‘recommended’) are made when there is confidence that the benefits either do or do not outweigh the harm and burden and costs of treatment. Where the magnitude of benefit or not is less certain a weaker grade 2 recommendation (‘suggested’) is made. Grade 1 recommendations can be applied uniformly to most patients whereas grade 2 recommendations require judicious application. The quality of evidence is graded as A (high quality randomized clinical trials), moderate (B) or low (C). This publication reports the key recommendations of the Writing Group.
