The effect of reduced blood donation due to the pandemic on blood product management has not yet been determined.Objectives: The aim of this study is to determine the rate of blood transfusion in COVID-19 patients.Material and Method: The 9-month period between 01.07.2019-31.03.2020 before the pandemic and the 9-month period between 01.04.2020-31.12.2021 during the pandemic period were determined as the time period for scanning the data. The numbers of whole blood, erythrocyte concentrate (EC) , fresh frozen plasma (FFP), pooled platelet concentrate, apheresis platelet concentrate , apheresis granulocyte concentrate, and cryoprecipitate concentrate produced in our hospital provided for COVID-19 services and intensive care units (ICU) or obtained from Kızılay were analyzed.Results: 56,936 patients, including the patients hospitalized in the ICU, were treated in our hospital in the 9-month period before the pandemic and 34,931 patients were hospitalized in the fisrst 9-month period during the pandemic. The number of blood products used in the operating room decreased by 62% and the number of blood products used throughout the hospital decreased by 22%. The number of blood donors decreased from 5414 in the pre-pandemic period to 3879 during the pandemic period. The transfusion rate per patient increased from 0.40 (the pre-pandemic period) to 0.47 (the pandemic period). The rate of transfusion per patient was 1.5 in the pre-pandemic period in ICUs while it was 1.6 during the pandemic period.Conclusion: Although the number of transfusions per patient increased during the pandemic in our center, it was shown that the number of inpatients and transfusions decreased with the decrease in elective surgeries.</p></abstract>

                            <p>ÖzetGiriş: Covid 19 salgını sırasında kan ürünü yönetimi ve ihtiyacı tartışmalı bir konudur. Pandemi nedeniyle azalan kan bağışının kan ürünü yönetimine etkisi henüz belirlenmemiştir.Amaç: Bu çalışmanın amacı, COVID-19 hastalarında kan transfüzyonu oranını belirlemektir.Gereç ve Yöntem: Pandemi öncesi 01.07.2019-31.03.2020 arasındaki 9 aylık dönem ve pandemi dönemindeki 01.04.2020-31.12.2021 arasındaki 9 aylık dönem verilerin taranma süresi olarak belirlendi. Hastanemizde üretilen ya da Kızılay’dan temin edilen; COVID-19 servisleri ve yoğun bakım ünitelerinde (YBÜ) kullanılan ; tam kan, eritrosit konsantresi (EC), taze donmuş plazma (TDP), havuzlanmış trombosit konsantresi, aferez trombosit konsantresi, aferez granülosit konsantresi ve kriyopresipitat konsantresi sayıları analiz edilmiştir.Sonuçlar: Pandemi öncesi 9 aylık dönemde yoğun bakımda yatan hastalar dahil 56.936 hasta hastanemizde tedavi gördü ve pandemi döneminde ilk 9 aylık dönemde 34.931 hasta hastaneye yatırıldı.  Ameliyathanede kullanılan kan ürünü sayısı %62, hastane genelinde kullanılan kan ürünü sayısı ise %22 azaldı. Pandemi öncesi dönemde 5414 olan kan bağışçısı sayısı, pandemi döneminde 3879&#039;a geriledi. Hasta başına transfüzyon oranı 0,40&#039;tan (pandemi öncesi dönem) 0,47&#039;ye (pandemi dönemi) yükseldi. Yoğun bakımlarda hasta başına transfüzyon oranı pandemi öncesi dönemde yüzde 1,5 iken pandemi döneminde yüzde 1,6 oldu.Sonuç: Pandemi sürecinde merkezimizde hasta başına düşen transfüzyon sayısı artmasına rağmen elektif cerrahilerin azalmasıyla birlikte yatan hasta ve transfüzyon sayılarının azaldığı gösterilmiştir.</p></trans-abstract>
