Association between methicillin-resistant Staphylococcus aureus colonization and infection may not differ by age group

We assessed whether age modified the association between methicillin-resistant Staphylococcus aureus (MRSA) anterior nares colonization and subsequent infection. Among 7,405 patients (9,511 admissions), MRSA colonization was significantly associated with infection (adjusted odds ratio, 13.7 [95% confidence interval, 7.3-25.7]) but did not differ significantly by age group.
