SEASONAL DYNAMICS OF BLOOD DONATION AND CLINICAL USE OF BLOOD COMPONENTS IN SECONDARY HEALTH INSTITUTIONS
Keywords:
blood donation, blood components, seasonal dynamicsAbstract
Blood donation is a vital element in the health system, providing blood and blood components necessary for the treatment of a large number of patients. Seasonal variations in blood donation often affect the availability of blood supplies, which can create difficulties in providing sufficient quantities of blood for various interventions, especially in secondary health institutions.
Objective: The aim of the paper is to analyze the seasonal dynamics of the number of blood donors and the amount of blood collected in a secondary health institution, as well as to study the clinical use of blood components in different seasons.
Materials and methods: The paper presents a retrospective analysis of issued and required blood components (whole blood, decanted erythrocytes, fresh frozen plasma and cryoprecipitate), for the needs of the PHI “General Hospital Kocani with extended action”, as well as for other health institutions.
Results: Four consecutive years were analyzed, in the PHI "Kocani General Hospital with Extended Activity", in terms of the needs for blood and blood components. In 2022, the following components were issued: whole blood, a total of 549 units, decanted erythrocytes, a total of 1740 units and fresh frozen plasma, a total of 793 units. In 2023, whole blood, a total of 567 units, decanted erythrocytes, a total of 1710 units, fresh frozen plasma, a total of 600 units and two units of cryoprecipitate, and in 2024, whole blood, a total of 558 units, decanted erythrocytes, a total of 2110 units and fresh frozen plasma, a total of 982 units. In 2025, whole blood, a total of 566 units, decanted erythrocytes, a total of 2696 units and fresh frozen plasma, a total of 746 units were issued. In terms of seasonal dynamics, at least during the summer months and during the holidays.
Conclusion: The analysis of the seasonal dynamics of blood donation and clinical use of blood components in a secondary health care facility shows that there are significant variations throughout the year. Most often, the decrease in the number of donors occurs in the summer months and during holidays, which leads to a shortage of blood supplies. Clinical use, in turn, adapts to these changes, but is also influenced by the seasonal prevalence of certain diseases and interventions. The results of this work emphasize the importance of dynamic planning and continuous education of the public about blood donation, in order to ensure a stable supply of blood products and quality health care.
