Evaluating the anemia and blood transfusion prevalence in the intensive care unit and its impact on mortality of patients

Introduction and objective: Anemia is regarded as one of the most common findings in ICU, resulting in extensive blood transfusions in this unit. Several factors are involved in increased patients’ hospitalization in hospital and increased mortality. Thus, the current research was carried out to evaluate the anemia and blood transfusion in ICU and its impact on the mortality of patients in educational hospitals of Urmia University of Medical Sciences.Methodology: the present study has been conducted based on prospective observations in intensive care units of educational hospitals of Urmia University of Medical Sciences .Demographic information of the۱۰۰ patients, blood transfusion, and hemoglobin level of patients were recorded at admission time since the seventh day to the ۳۰th day of hospitalization in the intensive care units. Logrank test was used to determine the survival time.Findings: Among the patients who had more than one week of hospitalization, ۱۰۰ patients met the inclusion criteria of study, and ۵۴ (۵۴%) were male and ۴۶ (۴۶%) were female. The mean age of patients was ۶۴.۲۴ ± ۱۶.۶۹. The mean survival time was ۲۷.۵ days for males and ۲۶ days for females. The survival time for people received blood was reported to be ۲۶.۸۳ days, and for those did not receive blood, it was reported to be ۲۶.۸۱ days. It was reported to be ۲۹.۴۴ days for patients with anemia at the time of admission and ۲۵.۱۱ days for those without anemia. The survival time for two groups was not significantly different in terms of sex (male and female) and receiving the blood (received or not), and the hemoglobin of admission time of patients between two anemia and non-anemia groups were among the variables, which had a significant difference (p<۰.۰۰۸) between two groups and findings revealed that non-anemia patients had a higher survival rate at the admission time compared to anemic patients.Discussion and conclusion: the variable of sex and receiving the blood and respiratory status during hospitalization time in ICU had no impact, while having or not having an anemia is considered an effective index during hospitalization time in ICU. Non-anemia people showed more survival rate than anemia patients.
