Evaluation of the Glasgow Coma Scale score in critically ill infectious disease patients

In this prospective study the Glasgow Coma Scale (GCS) score was evaluated in 107 critically ill infectious disease (ID) patients admitted to the Intensive Care Unit (ICU) during a 1-year period. Patients were separated into two groups: those affected by central nervous system (CNS) infections and those affected by infections other than of the CNS. There were no apparent differences in the first ICU day GCS score values between the two groups (11 +/- 4 vs. 11 +/- 4, p = 0.5318). Univariate logistic regression analysis confirmed a significant relationship between the first ICU day GCS score and the subsequent ICU mortality in the group of patients with CNS infections (r = 0.3152, p = 0.0015) but not in the group with infections not affecting the CNS (r = 0.0919, p = 0.1106). Our preliminary results suggest that the prognostic value of the GCS score is valid only in patients with CNS infections but not in other ID patients.
