Background: Healthcare-associated infections (HAIs) are among the most important threats to patient safety. When hospitalized children face these threats, there is morbidity, mortality, prolonged hospitalization, and increased healthcare costs. Research on local healthcare epidemiology is necessary to enhance collective knowledge and evidence formanaging this problem.
Methods: We performed a retrospective analysis of databases of patients who were diagnosed with HAIs at Chung-Ang University Hospital (CAUH) from 2007 through 2011. Cases were selected from the microbiology registry databases. The data on prevalence of HAIs in various wards and its annual trends were compared to previously reported nationwide data. Moreover, we analyzed the patterns of antibiotic susceptibility results for HAI pathogens.
Results: A total of 181 HAIs were identified in 122 patients. The HAI rate among pediatric patients at CAUH was 2.4/1,000 person-hospital days. Urinary tract infections (UTIs) (53 episodes, 29.3%) were the most common, followed by pneumonia (33 episodes, 18.2%). Staphylococcus aureus was found to be the most common gram-positive organism, whereas Escherichia coli was the most common gram-negative organism. Methicillin-resistant S. aureus (MRSA) comprised 84% of the S. aureus infections. Imipenem resistance was detected in 58.8% and 55.0% of Acinetobacter baumannii and Pseudomonas aeruginosa isolates, respectively.
Conclusion: Between 2007 and 2011, UTIs were the most common type of HAIs, and MRSA was the most common pediatric HAI pathogen, both in the general ward and intensive care unit at the CAUH. Further research on the epidemiology and pathogenesis of HAIs is necessary and prevention measures should be implemented to prevent HAIs in children.
