Objective: The results obtained in the newly opened intensive care unit may be different from serving a long time. Several methods have been developed to predict mortality such as APACHE II (Acute Physiology and Chronic Health Evaluation II) scoring system. In our study, we aimed to evaluate the first year results of our intensive care unit. Mateials and Methods: Between January to December 2013, patients who are in our third level general intensive care unit were retrospectively evaluated. Ages, sexes, causes of hospitalization, lengths of stay in the intensive care unit of patients were enrolled. According to the APACHE II score, patients were divided into 5 groups as 0-9, 10-19, 20-29, 30-39, 40 and over. The expected and actual mortality rates of each group were compared. Results: 183 of 218 patients who stayed more than 1 day in the intensive care were evaluated. There were 111 male and 72 female patients and their mean age was 63. Average length of stay was 8.75 days. All patient s mean APACHE II score was 16.36, mean predicting mortality was % 29.92, actual mortality was % 27.33. The standardized mortality ratio was (SMR) 0.91. In divided groups according to APACHE II; real mortality was lower than expected mortality in 0-9 and 10- 19 groups, higher than 30-39 and 40 over groups. Whereas there was no difference in the 20-29 group.
