Paradigm shift in transfusion practices during early COVID-19 pandemic: A single center retrospective study

Table 1 Restrictive transfusion guidelines from Association for the Advancement of Blood and Biotherapies published in 2016

Transfusion threshold	Patient population
Hemoglobin ≤ 7 g/dL	Hospitalized adult patients who are hemodynamically stable, including critically ill patients
Hemoglobin ≤ 8 g/dL	Patients undergoing orthopedic surgery, cardiac surgery, and those with preexisting cardiovascular disease

These recommendations do not apply to patients with acute coronary syndrome, severe thrombocytopenia (patients treated for hematological or oncological reasons who are at risk of bleeding), and chronic transfusion dependent anemia.
