A Survey on The Prevalence and Antibiotic Sensitivity of Nosocomial Infections in the Besat Hospital, Sanandaj, Iran

Nosocomial infections are the most significant problems in hospitals. The aim of this study was to investigate the prevalence of nosocomial infections and antibiotic resistance of bacteria isolated from patients.
This cross-sectional study was conducted in the Besat Hospital, Sanandaj, Iran from late March 2012 to early April 2013 on 32,400hospitalized patients. Bacteria were isolated from the sepatients and they were detected and identified through routine bacteriological methods. Then, an antibiotic sensitivity test was performed by the disc diffusion method. For data analysis, SPSS 16 and t-tests were applied (p Of the 32,400 patients that were hospitalized for more than 48 h, 327 (1%) were diagnosed with nosocomial infections according to the Centers for Disease Control and Prevention criteria. The nosocomial infections were related to UTIs (47.09%), blood infections (27.82%), wound infections (0.30%), and RTIs (16.81%). The most common bacterium was E. coli(68.51%) in the women’s ward and in urine samples (82.22%).The highest resistance was found for cotrimoxazole (57.47%).Statistically significant differences were not observed between the female and male groups with nosocomial infections (p>0.05).
Our research shows the existence of nosocomial infections in patients and antibiotic resistance in bacteria isolated from them. According to our results, appropriate programs form anagement of nosocomial infections and antibiotic resistance are necessary.
