Evaluation of blood consumption pattern and its relation with causes of mortality in ward of general ICU of Besat educational medical center of Hamadan in 2018-2019

Abstract Background and Objectives Administering unnecessary blood can cause many complications in patients and add to medical costs. This study aimed to evaluate blood consumption pattern and its relation with causes of mortality in Geneal ICU Ward of Besat Educational Medical Center of Hamadan in 2018-2019.   Materials and Methods This cross-sectional study was performed retrospectively in 2018-2019 on all eligible patients. A checklist was developed to collect demographic and clinical data. Finally, the data were analyzed by Kruskal-Wallis Test, Spearmanchr('39')s Correlation Coefficient, Chi-square Test, Mann-Whitney U by SPSS version 22.   Results 227 patients including 130 (57.3%) males and 97 females (42.7%) with the mean age of 39.02 ± 12.83 years were studied. The mean blood unit administered to each patient was 1.68 ± 1.02 and the mean hospital stay period was 8.43 ± 6.03 days. 19.4% of the patients died and the most common cause of death (8.4%) was attributed to brain and nervous system diseases/ damages. The most common type of blood products used was packed red blood cells (70%). The most common indication for blood prescription was surgery (75.3%) followed by bleeding (7.5%). There was a direct and significant relationship between the numberblood units and final outcome of the disease (p < 0.001).   Conclusions  Since the most common type of administered blood products was packed RBCs and there was a direct relationship between the number of prescribed blood units and the incidence of death, it is recommended to avoid unnecessary administration of packed RBCs.
