Background: Patients aided by mechanical ventilator are associated with critical illness bearing high mortality rate. Knowledge about predictors of mortality helps in clinical decision regarding the management and prognosis. To date there has been no comprehensive study about the predictors of mortality in patients with mechanical ventilator in Indonesia. Objective: To acknowledge the predictors of mortality in patients with mechanical ventilator in Cipto Mangunkusumo Hospital, Jakarta.
Methods: This retrospective cohort includes patients aided by mechanical ventilator in the Intensive Care Unit (ICU) of Cipto Mangunkusumo Hospital during 2010-2012. Clinical data and laboratory results as well as clinical outcome (survival or death) were obtained from medical records. Bivariate analysis was conducted to variables age, malignancies, acute respiratory distress syndrome (ARDS), shock, post-operative state, history of cardiac arrest, hyperglycemia, stroke, acute kidney injury, sepsis and hypoalbuminemia. Variables which made the cut were included in multivariate analysis with logistic regression.
Results: The study involved 242 patients with mortality rate of 45.4%. Age, malignancies, ARDS, shock, post-operative state, history of cardiac arrest, stroke, acute kidney injury, sepsis and hypoalbuminemia show statistical difference in bivariate analysis. Multivariate analysis gathers these predictors of mortality: acute kidney injury (OR 1,91; CI95% 1,08-3,39; p=0,002), shock (OR 2,13; CI95% 1,18-3,85; p=0,012), stroke (OR 3,39; CI95% 1,65-6,95; p=0,01), ARDS (OR 2,19; CI95% 1,10-4,35; p=0,025) and history of cardiac arrest (OR 4,85; CI95% 1,56-15,07; p=0,006). Conclusions: Acute kidney injury, shock, stroke, ARDS and history of cardiac arrest are independent predictors of mortality in patients aided by mechanical ventilator.
Key words: Predictor of mortality, mechanical ventilator
