  • Unique isolates from pediatric patients were counted once per patient. As per Clinical and Laboratory Standards Institute guidelines, there is less reliability for susceptibility in which there are <30 isolates. Hospital-acquired MRSA defined as cultures performed >48 h after admission. HA-MRSA, hospital-acquired methicillin-resistant Staphylococcus aureus; MSSA, methicillin-sensitive Staphylococcus aureus; —, no data.

  • * Significant differences (P ≤ .05).
