Method: This retrospective study included 391 of patients admitted to the ICU of an academic hospital during one year. Patients were categorized according to time of admission: working-hours and off-hours. Mortality was compared in the groups and associated factors of mortality were examined. Results: Two third of patients were admitted during off-hours. There was no significant difference in the GCS, age and length of stay among patients admitted during working-hours and off-hours. There was no difference in mortality among patients admitted during working-hours and off-hours Mor-tality was significantly higher in older and more severe cases, regardless of time of admission.
