Objectives: To determine the prevalence of infections, predominant organisms and their resistance pattern.

Materials and Methods: Prospective cohort study. All patients over 16 years old were occupying an intensive care unit bed over a 24-hour period. All patients admitted to the unit were evaluated on a daily basis for nosocomial infections in compliance with National Nosocomial Infections Surveillance System (NNISS) methodology. Infection site definitions were in agreement with Center for Diseases Control and Prevention (CDC) definitions.

Results: The NI incidence was 72%; ventilator associated pneumonia was the most common NI (41.2%), followed by urinary tract catheter-associated infection (28.2%), bloodstream infections (13.7%), and sepsis (6.9%), surgical site infection (4.6%). Pseudomonas spp. was the most common pathogen identified in the NIs (31.3%), followed by (%), and yeasts. The most frequent isolated microorganisms from patients were as follows: Pseudomonas aeruginosa (31.3%), Staphylococcus aureus (11.5%), Coagulase negative staphylococci (CoNS) (10.7%), Acinetobacter baumanii (9.2%), Candida spp. (8.4%), Escherichia coli (8.4%), Enterobacter spp. (4.6%), Enterococcus spp. (3.1%) and others (12.8%). Methicillin resistance was 96% at staphylococci. It was observed Gram-negative microorganisms had multi-resistant pattern.

Conclusion: The rate of nosocomial infection is high in intensive care unit patient, especially for respiratory infections. The predominant bacteria were P. aeruginosa and S. aureus, CoNS and A. baumanii (resistant organisms). This study documents the clinical impression that prevalence rates of intensive care unit-acquired infections are high and suggests that preventive measures are important for reducing the occurrence of infection in critically ill patients.©2005, Fırat Üniversitesi, Tıp Fakültesi
