Aim: Correct indications of blood components (BC) are the key to effective and safe haemotherapy. The aim of this study was to evaluate the indication criteria of BC, to compare the changes in BC indications between two periods and to improve the quality of haemotherapy at the Regional Hospital Liberec, as (KNL).

Materials and methods: The study population consisted of all BCs (erythrocytes, platelets, plasma) administered in the KNL in the period from 1 October 2020 to 30 September 2021 and from 1 August 2022 to 31 July 2023. From the database of the laboratory information system, the laboratory results of BC recipients were matched to each BC: haemoglobin (Hb), platelet count, and prothrombin time - ratio (PT-R). These results were matched if they were tested before the administration of the BC within the previous calendar day, i.e., within 48 hours before the issue of the BC.

Results: In 2020/21, 35% of red blood cells, leucocyte-depleted in additive solution (ED) were administered to patients with Hb > 80 g/l, and in 2022/23, 32% of ED. Comparison of mean Hb values revealed no statistically significant difference between the periods (p = 0.61), and the approach to ED indications did not change. In 2020/2021, 29% of platelet BCs were administered to patients with platelet counts > 50 × 109/l, and in 2022/2023, 16% of platelet BCs. Platelet BCs were issued to patients with lower platelet counts in 2022/23 than in 2020/21 (p < 0.001). Whether this was a rationalization of indications or a different patient make-up, cannot be assessed. In 2020/2021, 52% of plasma, fresh frozen (P) was administered to patients with a PT-R ≤ 1.5, and in 2022/2023, 47% of P. When comparing mean PT-R values, there was no statistically significant difference between the evaluated periods (p = 0.45).

Conclusion: The approach to erythrocyte and plasma BC indications was consistent. A more considered approach was taken for plasma BCs for borderline indications, when compared with the literature. For platelet BCs, indications were rationalized or patient make-up was different. In general, BCs were rationally indicated. We will continue to work with the results of the study.
