Factors associated with red blood cell transfusion among hospitalized patients: a cross-sectional study

Red blood cell(RBC)transfusion is a clinically effective therapy in anemia,for example in patients with malignancies(Shander et al.,2020),bleeding(Odutayo et al.,2017),and preoperative anemia(Pad-manabhan et al.,2019).The past few decades have witnessed a shortage of blood for transfusion due to limited health insurance coverage for blood use and the rapid expansion of hospitals(Chen et al.,2011;Shi et al.,2014).Blood donation levels may easily be affected by general changes in the environment,policy,major events such as disasters,and public sentiment(Hu et al.,2019).
