  • Cells show the mean extra length of stay (in days) with 95% CIs in parentheses. Based on nine hospitals with admissions between 1 January 2005 and 31 December 2010. Separate estimates were made for admissions that ended in death and discharge. The total length of stay is the standard bed time plus the ICU bed time (see figure 2).

  • BSI, bloodstream infection; CNS, coagulase-negative staphylococci; ICU, intensive care unit; MRSA, methicillin-resistant Staphylococcus aureus; MSSA, methicillin-sensitive S aureus; SAB, S aureus bacteraemia.
