About the necessity to improve blood donor deferral

Rationale: In 2021, a mandatory change in the study of markers of infections in blood donors (refusal of confirmatory studies, etc.) at the Republican Blood Transfusion Station (RPSK, Ufa) was combined with a significant increase in the blood donors deferrals.Objective: to compare the frequency and structure of donor deferrals due to the detection of infection markers in 2021 and 2022. hypothesis: unchanged order of donor examination in 2021 and 2022. will lead to the maintenance of an increased proportion of donor deferrals.Methods: Based on the results of the work of the RSPK in 2020-2022 and using themethod of continuous observation, we compared the number of primary and repeat donors, their donations and the number of people diverted from donation after identifying markers of blood-borne infections. The results were assessed using descriptive and inductive statistics at a significance level of 0.05.Results: In 2021, the part of donors deferred due to infection markers increased significantly: first time - by 1.2% (p
