    This study is a descriptive, retrospective, and observational analysis. The sample consisted of all confirmed cases of extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae in patients attended at the José Casimiro Ulloa Emergency Hospital during 2011. Data collection was carried out using records from the Clinical Analysis Laboratory of the Clinical Pathology Department at José Casimiro Ulloa Emergency Hospital, as well as from the Surgery, Medicine, Intensive Care Unit (ICU), Intermediate Care Unit (IMCU), Traumatology services, and outpatients. The incidence of ESBL-producing Enterobacteriaceae was calculated as a percentage, considering the microorganism species, type of sample, originating service, and care conditions. During the year, 751 Enterobacteriaceae isolates were obtained, of which 60 were confirmed as ESBL-producing cases (8%). The most common species were Escherichia coli (83.8%, 629 isolates), Enterobacter aerogenes (3.5%, 26 isolates), and Klebsiella pneumoniae (2.0%, 15 isolates), compared to the total isolates. Among the confirmed cases, the percentages were: Escherichia coli, 8.4% (53/629 isolates); Klebsiella pneumoniae, 20.0% (3/15 isolates); and Enterobacter aerogenes, 7.7% (2/26 isolates). The majority of confirmed ESBL cases were from outpatients, representing 75.0% (45 cases), whereas hospitalized patients accounted for 25.0% (15 cases). At the hospital service level, Surgery had the highest percentage of confirmed ESBL cases (33.3%), followed by Medicine (26.7%) and the ICU (20%). The incidence of ESBL-producing Enterobacteriaceae in patients attended at José Casimiro Ulloa Emergency Hospital during 2011 was low, at 8% (60/751), compared to data from studies conducted in other countries, but very similar to other national studies. An association was found between the bacterial species producing ESBL and results reported in other studies conducted in Latin America.
