Background:
Carbapenemase-producing Enterobacteriaceae (CPE) has become a significant problem in terms of public health and clinical outcome.
Objective:
To assess the epidemiology, treatment and mortality in patients with infection due to CPE.
Material And Methods:
A retrospective analysis of 163 patients with CPE infection was carried out in a university hospital from July 2013 to October 2015.
Results:
A total of 163 patients were included over the study period. Klebsiella pneumoniae was isolated in 95.1% of cases, and most of carbapenemases belonged to the OXA-48 group (93.0%). Acquisition was nosocomial in 124 cases (77.0%), healthcare-associated in 30 (18.6%), and 7 cases (4.3%) were community-acquired. The most frequent infections identified in this study were urinary tract (48.4%) and respiratory (19.5%) infections. Approximately half of the patients received antibiotic monotherapy. The 30-day mortality rate was 23.3%. Multivariate analysis revealed that the presence of septic shock at diagnosis (OR 4.2; IC 95% 1.5-11) was independently associated with an increase in death during the first month, unable to identify association with inappropriate antibiotic treatment.
Discussion:
Further studies are needed to clarify whether antibiotic treatment of EPC infections should be combined or if monotherapy might be sufficient in mild infections.

HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
