Abstract
A total of 82 patients (mean age 63.7±16.4, range 20-96, 51 male vs 31 female) followed in medical intensive care unit (ICU) were retrospectively analyzed. Mortality rate was highest (52.0%) in patients with community acquired pneumonia(CAP). Pseudomonas aeruginosa and flora bacteria were detected in 29.2% of sputum cultures obtained from patients with community acquired infections. Pseudomonas aeruginosa (22.2%), Klebsiella pneumoniae (16.7%) and Acinetobacter spp (16.7%) were the most frequent microorganisms isolated from tracheal secrete cultures of cases with severe CAP and nosocomial pneumonia (NCP). Increase in complication rate was statistically significant in patients who were hospitalized more than 14 days in ICU compared with patients who stayed 14 days (78.6% vs 30.2%) (p=0.00003). Mortality rate was 40.2% and the most significant factor affecting mortality was found to be development of complications.
