Evaluation of hemoglobin concentration and its relationship with clinical outcome in non-traumatic patients of the General ICU of Besat Educational and Medical Center of Hamadan in 2020-2021

Mortality is one of the common consequences of non-trauma patients (NTP) admitted to the intensive care unit. In this study, hemoglobin concentration and its relationship with clinical outcome in NTP was investigated

This cross-sectional study was performed on the records of 400 non-trauma patients admitted to the General Intensive Care Unit of Besat Hospital in Hamadan during 2020-2022 in terms of hemoglobin concentration and its relationship with clinical outcome. Study data were analyzed using SPSS software version 23 and Student t-tests, one-way analysis of variance, and Pearson correlation coefficient.

In this Cross-sectional study, cancer (18.8%), drug poisoning (14.8%), poisoning (14.5%), and DKA (8.8%) were the most common causes of non-trauma hospitalization. The incidence of in-hospital death was 18.8%. Sepsis, pulmonary embolism, myocardial infarction, meningitis and DIC with 46.7%, 22.7%, 18.7%, 6.7% and 5.3% were the most common causes of death, respectively. There was a significant relationship between hemoglobin concentration with age, sex and duration of hospitalization (p<0.05). A significant relationship was observed between lower hemoglobin concentration before and during hospitalization with increased mortality (p<0.001).

In the present study, the hemoglobin of non-trauma patients decreased during hospitalization compared to pre-hospitalization period and this decrease in hemoglobin level was associated with increased mortality of non-trauma patients in the hospital.
