Abstract:
BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) nasal colonization has been known as a predictor of intensive care unit (ICU)-acquired MRSA infections. We performed this study to survey the nasal colonization of MRSA among the patients admitted to an ICU and analyze risk factors associated with the colonization. METHODS: A retrospective 1:1 matched case-control study was conducted with patients admitted to the ICU from March to December 2010 at Samsung Changwon Hospital. RESULTS: A total of 602 patients among 846 patients admitted to the ICU during the study period were evaluated. The prevalence of nasal MRSA colonization was 67 (11.1%) of 602. Other factors, including underlying renal disease (odds ratio [OR]=12.37, 95% confidence interval [CI] 3.60-42.54; P<0.001), MRSA infection within the previous 3 months (OR=7.43, 95% CI 1.31-42.05; P=0.023), nursing home resident within the previous 1 month (OR=6.25, 95% CI 1.82-21.53; P=0.004), surgical procedure within the previous 1 month (OR=5.93, 95% CI 1.86-18.85; P=0.003), and current use of nasogastric tube (OR=4.98, 95% CI 1.84-13.45; P=0.002) were independently associated with nasal MRSA colonization in patients admitted to ICU. CONCLUSION: A significant number of patients admitted to the ICU in a secondary hospital were colonized with MRSA. The present study showed the possible impact of the presence of a nasogastric tube on the nasal colonization by MRSA. More effective infection control procedures must be developed for patients with nasogastric tube use.
