Purpose: The study aimed to determine whether improvements in intensive care unit (ICU) structural environment affect the incidence of ICU-acquired infections (IAIs), particularly those caused by multidrug-resistant pathogens. %26lt;br%26gt;Methods: The incidence of IAI and the number of infections caused by organisms during the 6 months immediately before ICU renovation and during the 6 months immediately after ICU renovation were compared. The observational duration was prolonged for an additional 1 year after recruiting the after-renovation data to observe if the found effect of ICU structural renovation is maintained. The relevant data were prospectively gathered. %26lt;br%26gt;Results: The overall IAI incidence and distribution of infection site showed no difference in both periods. In IAI-causing pathogens, no considerable difference was found between before and after renovation, except for Acinetobacter baumannii. In comparison of the major pathogens%26apos; identification rate between the entire hospital and the renovated ICU during the study periods, only A baumannii cases in the renovated ICU significantly decreased. However, the reduction of the IAI cases by A baumannii was not sustained for more than 1 year. %26lt;br%26gt;Conclusions: These results suggest that structural ICU renovations only may not improve overall IAI incidence, except for transient decrease in IAI by A baumannii.
