无偿献血全血间隔期调整的专家共识OA

Voluntary blood donation is the cornerstone of safe clinical blood use.In the context of demographic transi-tion and growing healthcare demand,scientifically determining an appropriate whole blood donation interval has become an important strategy for enhancing blood supply capacity.The current 6-month interval for whole blood donation in China dif-fers from prevailing international practices.Based on the WHO Handbook for Guideline Development,this consensus sys-tematically reviewed and evaluated the evidence on whole blood donation intervals,assessed the quality of evidence using the Grading of Recommendations Assessment,Development and Evaluation(GRADE)approach,and conducted expert consultation using a modified Delphi method to develop consensus recommendations.Drawing on physiological evidence and findings from evidence-based studies,the consensus systematically evaluated the effects of shortening the donation interval on donor health,blood quality,and recipient safety,as well as its potential contribution to blood supply.It is recommended that,with strengthened health monitoring,the whole blood donation interval be reduced to 3 months,which can effectively enhance blood supply while ensuring safety,thereby providing an evidence-based basis for optimizing blood donation policies in China.
