Effect of Baseline Datas on the Survival of Intensive Care Unit Patients

Abstract

Aim: We investigated demographic features and systemic diseases which affect mortality and the importance of the biochemical analyzes on admission in patients admitted to intensive care unit (ICU). Methods: We included 1748 patients (55% male) who were admitted to the ICU at our hospital between 2012 and 2014. The mean age of the patients was 61.8±19.2 years. Data on age, gender, presence of systemic diseases and surgery, duration of hospitalization and biochemical parameters on admission were analyzed. Results: The mean length of hospitalization was 18.4±34.3 (median=6) days. 32.1% of patients were postoperative patients. 45.7% of patients died. The rate of presence of multiple diseases, nervous system, cerebrovascular, and cardiovascular diseases and laboratory parameters including urea, creatinine, lactate dehydrogenase (LDH), and leucocytes were significantly higher and the mean albumin level was lower in patients who died compared to those in patients who were discharged from the hospital. Age, creatinine, albumin and LDH values were found to be significantly important factors by multivariate analysis conducted to examine predictors of mortality while gender, presence of multiple diseases, diagnostic code and being post-operative or not were found to have no significant importance. Conclusion: Baseline evaluation of pathologies that may play a role in mortality of ICU patients may be important for survival prediction. Evaluation of these factors on admission may contribute to development of different approaches to high-risk patients.
