Abstract
Background and Objectives
Covid-19 was declared a public health emergency by World Health Organization in jan 2020. Public fear, quarantine, and shutdown created an unpredictable situation for healthcare services worldwide, which created a great challenge for blood transfusion services.
Materials and Methods
In a cross-sectional study, the data about the request, distribution, and waste of blood products were collected and compared in two time periods (March and February 2019 and March and February 2020) before and at the time or Covid-19 pandemic with test of proportion. The poisson regression test was used to compare the amount of waste, request, and distribution of blood products in two consecutive years.
Results
The request for red blood cells before the pandemic was 920,591 units, but it decreased by 18% to 754,052 units, and the distribution of red blood cells decreased by 17.3% at the time of pandemic, because of the cancellation of surgeries and general quarantine. The RBC wastage decreased from 25878 to 12837 units, a reduction of 50.3% (p = 0.03). However, the demand for leukoreduced red blood cells rose by 10.8%, yet wastage also increased by 8.8%. Waste in red blood cell bags for infants quadrupled during the pandemic. Plasma requests decreased by 4.9%, with a 7.2% decline in distribution, yet plasma waste increased by 6.8%. At pandemic time, Platelet requests decreased by 19%, distribution decreased by 15.6%, and waste decreased by 32.3%.
Conclusions
During the COVID-19 pandemic, the waste of RBCs and platelets was reduced. The distribution-to-demand ratio remained relatively stable throughout the pandemic time.
