Abstract
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. 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 the100 patients, blood transfusion, and hemoglobin level of patients were recorded at admission time since the seventh day to the 30th day of hospitalization in the intensive care units. Logrank test was used to determine the survival time. Among the patients who had more than one week of hospitalization, 100 patients met the inclusion criteria of study, and 54 (54%) were male and 46 (46%) were female. The mean age of patients was 64.24 ± 16.69. The mean survival time was 27.5 days for males and 26 days for females. The survival time for people received blood was reported to be 26.83 days, and for those did not receive blood, it was reported to be 26.81 days. It was reported to be 29.44 days for patients with anemia at the time of admission and 25.11 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<0.008) between two groups and findings revealed that nonanemia patients had a higher survival rate at the admission time compared to anemic patients. 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.
