In our control group many patients were culture negative and thus we could not be certain that they did not have an MDRO infection&#44; however&#44; we did not include any patients who had no cultures collected&#46;

in these patients&#44; we could not determine if they received appropriate therapy&#44; so they were excluded from any analysis of this factor&#46; One other limitation is that&#44; our sample size lacked the power to show a difference in mortality&#44; so the observed lack of difference may have not have been present in a larger study&#46; It is also possible that the lack of significant difference in mortality between the two groups may be partially explained by differences in infection sites&#46; The high frequency of urinary tract infections may reflect the time period of this study&#44; and its having been conducted prior to a change in the hospital policy for daily assessment of the need for bladder catheters&#46; Finally this study is limited by its retrospective design and it was conducted at a single center in a single ICU over a few months and thus may not be fully representative of other hospitals&#46; Moreover the study was performed seven years ago and this may affect the applicability and the validity of our findings&#44;
