The incidence density of ward-acquired ESBL-E per 1,000 patient-days at risk was 4.6 in both intervention periods, regardless of the type of precaution taken. Contact precautions appeared to be slightly less effective for Escherichia coli (3.6 per 1,000 patient-days in contact precautions vs. 3.5 in standard), compared with Klebsiella pneumoniae (1.8 vs. 2.2).
A multivariate analysis controlled for screening compliance, colonization pressure, and length of stay, study site, and season of year. It showed that strict contact precautions did not reduce the risk of ward-acquired ESBL-E carriage.
