Mortality Rate In Intensive Care Units of Tertiary Health Institutions and Identifying Risk Factors: Analysis of 3945 Patients

Abstract

Objective:To evaluate demographic data of patients hospitalized in the intensive care unit (ICU) of a tertiary health institution and to reveal demographic and laboratory parameters associated with mortality.Methods:Between January 2008 and 2013, patients who were hospitalized in our clinic were retrospectively analyzed. During the evaluation, the demographic characteristics of patients; creatinine, urea, uric acid, albumin, LDH, ALT, AST, sodium, and hemoglobin levels; hematocrit; and white blood cell and platelet counts were assessed. The patients were then divided into two groups according to those who died and those transferred to a service.Results:Between January 2008 and 2013, a total of 3945 patients were enrolled. In patients who died in the ICU, the average age, presence of an operation history, and hospitalization time in the ICU were statistically significant. After the evaluation, laboratory parameters including urea, creatinine, uric acid, and LDH levels and white blood cell count were significantly higher in patients who died in the ICU than in those who were transferred to a relevant service as healthy patients. Further, serum albumin, and hemoglobin levels; hematocrit; and platelet count were significantly lower in patients who died.Conclusion:In elderly patients, the presence of am operation history and elevated urea, creatinine, uric acid, and LDH levels and white blood cell counts and decreased albumin and hemoglobin levels; platelet counts; and hematocrit were significantly associated with higher mortality rates in the ICU.
