The Prevalence and Bacterial Etiology of Nosocomial Infections in Poursina Hospital of Rasht During 2013-2015

Aims: The present study aimed to determine the prevalence of nosocomial infections and their bacterial agents in patients admitted to Poursina Medical and Educational Center of Rasht. Materials & Methods: The present retrospective descriptive study was conducted by referring to the Infection Control Unit of Poursina hospital and investigating the records of patients with culture-positive nosocomial infections from April 2013 until the end of September 2015. Bacterial agents were diagnosed based on the standard microbiological tests. Results: During the research period, urinary tract and blood infections were reported as the highest and lowest nosocomial infections, respectively. The most common strains causing nosocomial infections were Acinetobacter spp. (24.7%) (as the most common strain causing respiratory infection), Escherichia coli (22.9%) (as the most common strain causing urinary tract infection), and Enterobacter spp. (19.9%) (as the most common strain causing postoperative infection). Based on the frequency distribution of bacterial strains in hospital wards, Acinetobacter spp was reported as the most common strain isolated from patients in the intensive care unit. Conclusion: According to the present study results, Acinetobacter spp was the most common strain isolated, and UTIs were the most common type of infection. Due to the prevalence of UTIs and the financial, physical, and social damage they impose to the whole country and the constant change of common pathogens and their susceptibility and antibiotic resistance patterns, it is necessary to conduct studies on this issue in the academic centers of each province at regular intervals.
