Red cell units saved during the COVID-19 pandemic. (A) The percent of units saved per patient during COVID-19 period compared with their individual average increase in FCR from pre–COVID-19 to COVID-19 procedures (• represents individual patients, n = 50). (B) Average red cell units transfused per RCE pre–COVID-19 and during COVID-19 for patients whose hematocrit was maintained at baseline (↔ Hct, n = 20) vs patients whose hematocrits were raised above baseline in ≥75% of procedures (↑ Hct, n = 11). (C) Percent of red cell units saved per patient and (D) average %FCR raised per RCE in COVID-19 procedures for patients whose programmed end hematocrit was not (↔ Hct, n = 20) or was increased (↑ Hct, n = 11) in ≥ 75% of procedures. *P < .05, ***P < .001.
