Extended-spectrum beta-lactamase-producing Enterobacterales in patients with suspected sepsis in an acute care setting in Skåne, Sweden: a cohort study.

LUND (Sweden); SWEDEN

Epidemiological data on extended-spectrum beta-lactamase (ESBL)-producing Enterobacterales are most often based on microbiological laboratory isolates and do not consider important clinical data such as infection or colonisation, treatment, and outcome. This study aimed to assess prevalence of ESBL-producing Enterobacterales as the cause of infection in patients with suspected sepsis in the emergency department based on clinical data. It also examined the number of patients with suspected sepsis who had ESBL-producing pathogens, comparing estimates that were based on laboratory data versus a combination of laboratory and clinical data. Patients with suspected sepsis in the emergency department at Skåne University Hospital, Lund, Sweden were included consecutively. Data were collected retrospectively from medical records. Of the 764 included patients, 223 patients had growth of Enterobacterales in any specimen (i.e. colonisation or infection according to laboratory data), while 191 patients had Enterobacterales detected in the blood or in the suspected focus of infection (i.e. an infection according to clinical and laboratory data). Eighteen patients had ESBL-producing Enterobacterales in any clinical specimen, 11 of whom had an infection with ESBL-producing Enterobacterales, resulting in a prevalence of infections with ESBL-producing Enterobacterales in infected patients with suspected sepsis of 1.8%. The number of patients with ESBL-producing Enterobacterales was not significantly different when infection was defined using laboratory data alone versus a combination of laboratory and clinical data [18/223 (8.1%) vs 11/191 (5.8%), p = 0.36]. The prevalence of ESBL-producing Enterobacterales infections among patients with suspected sepsis is low in an acute care setting in Sweden. [ABSTRACT FROM AUTHOR]
