Abstract
Objectives The red blood cell (RBC) D antigen is highly immunogenic, and anti-D alloimmunization can cause hemolytic transfusion reactions and hemolytic disease of the fetus and newborn. This study examined how RhD-negative patients who required packed RBCs (pRBCs) were handled during the COVID-19 pandemic and whether policies and practices on RhD-positive pRBC allocation to RhD-negative patients changed. Methods The Association for the Advancement of Blood & Biotherapies (AABB) Clinical Hemotherapy Subsection distributed a 17-question survey to physician AABB members to elucidate the impact of the COVID-19 pandemic on the policies and practices governing the provision of RhD-positive pRBCs to RhD-negative patients. Results There were 215 respondents who started the survey, but only 104 answered all the questions. Most institutional policies (130/155 [83.87%]) and personal practices (100/126 [79.37%]) on pRBC selection did not change during the COVID-19 pandemic. The practice of switching back to RhD-negative pRBCs after administration of RhD-positive pRBCs is variable. More than half of respondents (56/104 [53.85%]) reported offering Rh immunoglobulin to any Rh-negative patients who received RhD-positive pRBCs. Conclusions Despite RhD-negative pRBC supply challenges, most institutional policies and personal practices on when to provide RhD-positive pRBCs to RhD-negative patients did not change during the pandemic.
