Infections due to carbapenem-resistant Enterobacteriaceae (CRE) represent a growing problem nationally, are difficult to treat, and are associated with high mortality rates. Features of CRE infection within Connecticut, a nonendemic area, have not been described in the medical literature. We report a case series of five patients with CRE isolates who were treated at Hartford Hospital in Hartford, Connecticut from 2011-2013. CRE isolates included three Klebsiella pneumoniae, one Klebsiella oxytoca, and two E. coli. Three isolates were obtained from urine cultures, one from respiratory culture, and one from blood and wound cultures. Four patients survived the hospital course, including three patients who had a hospital stay of >100 days. In this nonendemic hospital, CRE infections were identified mainly in patients with multiple comorbidities who underwent catheter placement and surgical procedures, had contact with the health care system in the preceding 90 days, and tended to have prolonged, complicated hospital courses.
