Patients colonized with carbapenem-susceptible
Pseudomonas aeruginosa
(CSPA) strains upon admission to the intensive care unit (ICU) tend to be quickly followed by detected carbapenem-resistant
P. aeruginosa
strains after admission.
Objective
To assess the risk factors associated with the quick loss of carbapenem susceptibility and to identify time threshold of prior antimicrobial exposure for the loss during ICU stay.
Setting
A tertiary-care teaching hospital with 2560 beds located in the northwest region of China.
Method
A retrospective observational study was conducted between January 2013 and April 2016 at ICUs. Logistic regression analysis was used to assess risk factors, and receiver operating characteristic (ROC) analyses were constructed to identify the time threshold.
Main outcome measure
The time threshold and risk factors for the quick loss of carbapenem susceptibility.
Results
Among the 84 patients with CSPA initially, 32 (38.1%) patients were observed to have a loss of carbapenem susceptibility during ICU stay. Logistic regression analyses showed that previous carbapenem exposure was only independently associated with the loss of carbapenem susceptibility (odds ratio 13.16; 95% CI 3.13–55.24;
