Extra length of stay (in days) in a standard bed and ICU bed due to a hospital-acquired bloodstream infection

Bloodstream	Standard bed		ICU bed
Infection	Died	Discharged	Died	Discharged
BSI and Gram positive	1.0 (−3.9 to 5.6)	9.8 (7.7 to 12.6)	4.0 (2.6 to 5.7)	0.9 (0.4 to 1.8)
BSI with SAB
All	−1.5 (−6.8 to 6.1)	12.1 (6.7 to 15.3)	1.4 (0.5 to 3.0)	0.9 (0.1 to 2.9)
MRSA	−1.6 (−12.6 to 12.6)	12.8 (6.2 to 26.1)	3.1 (0.5 to 7.2)	3.1 (0.4 to 13.2)
MSSA	2.7 (−2.6 to 9.7)	11.0 (6.4 to 14.9)	0.7 (−0.3 to 2.0)	0.4 (0.0 to 0.8)
BSI with CNS	3.5 (−4.0 to 13.4)	9.8 (3.6 to 14.6)	6.0 (3.3 to 10.0)	1.4 (0.6 to 2.5)
BSI and Gram negative
All	−3.9 (−8.7 to −0.4)	2.7 (−4.1 to 6.1)	3.0 (1.4 to 4.5)	0.6 (0.3 to 1.0)
Escherichia coli	−3.3 (−9.3 to 7.9)	1.1 (−13.2 to 5.7)	2.5 (0.4 to 4.7)	0.5 (−0.1 to 0.9)
Pseudomonas	−5.4 (−11.6 to 9.2)	5.6 (−6.4 to 14.3)	3.2 (0.8 to 7.1)	0.5 (0.3 to 1.2)

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.
