*MRSA, methicillin-resistant Staphylococcus aureus; MSSA, methicillin-sensitive S. aureus; LOS, length of stay in hospital; IQR, interquartile range †A particular staphylococcal type could not be determined for 11% of the records; thus, added together, numbers in the MRSA, MSSA, and Other staphylococci groups do not equal the number in All types of staphylococcal infection group. Diagnostic groups are not mutually exclusive; therefore, percentages in columns total >100.
