Incidence rate of extensively-drug resistant Acinetobacter baumannii (XDR-AB) acquisition (number of cases who had a positive culture per 1000 patient days) in the open-bay intensive care unit (ICU) of our facility per each numerical week after enhanced terminal disinfection (ETD). N.B. -Each patient, who resided in the ICU during the corresponding numerical week, was counted once per each numerical week depending on the date of acquisition only and it was not cumulative. -The incidence rate of XDR-AB was calculated from Week 1 to Week 16 after ETD since the number of patient days per week was > 50 days (refer to Figure-1).
