Influence of ABO blood group polymorphism on mortality in intensive care unit patients
Critical Care volume 11, Article number: P446 (2007)
Blood groups may be related to differences in inflammatory responses . We looked at blood group as a risk factor for ICU mortality in general and for patients with sepsis.
Data were retrospectively collected from all 11,553 patients that were admitted from 1997 to 2005 to our medical/surgical ICU.
ICU mortality and SAPS II score for different blood groups are shown in Table 1. P values are given for the difference between blood groups A and O. No differences were found for age, gender, and reason for admission. No influence of rhesus blood group type was seen on mortality.
Blood group O is associated with a higher ICU mortality rate than blood group A. The relative risk increase for ICU mortality was 18% for all patients and 30% for patients with severe sepsis.
