Active surveillance for carbapenem- resistant enterobacteriaceae using stool specimens submitted for testing for Clostridium difficile

Active surveillance to identify asymptomatic carriers of carbapenemresistant Enterobacteriaceae (CRE) is a recommended strategy for CRE control in healthcare facilities. Active surveillance using stool specimens tested for Clostridium difficile is a relatively low-cost strategy to detect CRE carriers. Further evaluation of this and other risk factor-based active surveillance strategies is warranted.
