Carbapenemase-producing Enterobacteriaceae colonization was associated with a statistically significant increase of the subdistribution hazard ratio for ICU mortality ( subdistribution hazard ratio = @ ; @ % CI , @-@ @ ) , not explained by an increased daily hazard of dying ( cause-specific hazard ratio for death = @ ; @ % CI , @-@ @ ) , but by an increased length of stay ( cause-specific hazard ratio for discharge alive = @ ; @ % CI , @-@ @ ) .
