Treatment of the nosocomial infections is complicated especially in children due to an increase in the antibiotic-resistant bacteria.


The aim of this study was to survey the nosocomial infections in children and determine the antibiotic susceptibility of their causative organisms in teaching hospitals in the north of Iran.


The investigation was designed as a retrospective cross-sectional study. The study population consisted of patients under 12 years old, which were hospitalized in three teaching hospitals in the north of Iran and had symptoms of nosocomial infections in 2012. The required data of patients were extracted and entered in the information forms. The collected data were analyzed using SPSS (ver. 16). Descriptive statistics and Fisher's exact tests (Monte Carlo) were used.


Out of the total number of 34556 hospitalized patients in three teaching hospitals, 61 (0.17%) patients were children under 12 years old age with nosocomial infection from which 50.81% were girls and 49.18% were boys. Most of these patients (55.73%) were admitted to the burn unit. The most common type of nosocomial infection (49.18%) was wound infection. Pseudomonas spp. (36.84%) and Acinetobacter spp. (28.02%) were the most common bacteria isolated from the clinical specimens. All the Acinetobacter spp. were multidrug-resistant. All the gram negative and gram positive bacterial species in our study showed high resistance to antibiotics.


The rate of nosocomial infections was low in our study because the detection of nosocomial infection was based on the clinical grounds in most cases and laboratory reports might contain false-negative results. These results provide useful information for future large scale surveillance in the context of prevention programs.
