Risk factors for mortality in patients admitted to intensive care units with pneumonia.

ABSTRACT: Despite the high mortality in patients with pneumonia admitted to an ICU, data on risk factors for death remain limited.In this secondary analysis of PROTECT (Prophylaxis for Thromboembolism in Critical Care Trial), we focused on the patients admitted to ICU with a primary diagnosis of pneumonia. The primary outcome for this study was 90-day hospital mortality and the secondary outcome was 90-day ICU mortality. Cox regression model was conducted to examine the relationship between baseline and time-dependent variables and hospital and ICU mortality.Six hundred sixty seven patients admitted with pneumonia (43.8 % females) were included in our analysis, with a mean age of 60.7 years and mean APACHE II score of 21.3. During follow-up, 111 patients (16.6 %) died in ICU and in total, 149 (22.3 %) died in hospital. Multivariable analysis demonstrated significant independent risk factors for hospital mortality including male sex (hazard ratio (HR)?=?1.5, 95 % confidence interval (CI): 1.1 - 2.2, p-value?=?0.021), higher APACHE II score (HR?=?1.2, 95 % CI: 1.1 - 1.4, p-value?
