Objective: This study aims to determine the mortality rate and factors affecting the mortality of patients in the general intensive care unit (GICU) of a state hospital.

Material and Methods: Data of patients who were hospitalized between January 2012 and March 2013 in GICU of the Konya Numune Hospital were retrospectively analyzed. Demographic characteristics and clinical data of patients were recorded. Patients were divided into two groups as survivors and dead. Factors that may affect the mortality of patients were examined.

Results: A total of 930 patients were included. Median age of patients was 73 (63–80) years. Of 930 patients, 357 (38.4%) died and 573 (61.6%) survived; 457 (49.1%) patients were male. Median Glasgow coma scale (GCS) of the group was 13 (8–15) and median acute physiology and chronic health evaluation 2 score was 17 (13–21). Median duration of hospitalization was 4 (2–12) days. The number of patients who were treated with invasive mechanical ventilation was 380 (40.9%), while the number of patients who were treated with erythrocyte suspension, fresh frozen plasma, platelets, and albumin supplementation were 286 (30.8%), 354 (38.1%), 14 (1.5%), and 56 (6%), respectively. Logistic regression analysis revealed that advanced age, transfer of patients from level 2 ICU to level 3, mechanical ventilation, and renal replacement therapies were the factors that increased ICU mortality. High GCS and admission from emergency service to level 2 ICU were factors reducing ICU mortality.

Conclusion: Longer duration of hospitalization and increased number and diversity of interventions were related to increased mortality. The mortality rate of patients in the state hospital ICUs can be reduced if the risk factors of patients were appropriately identified.
