Isenberg Y, Zamstein N, Horesh N, et al. - In this retrospective analysis, researchers evaluated risk factors for bacteremia after endoscopic procedures, looking primarily at neutropenia. The sample consisted of all inpatients in a tertiary center in Israel undergoing endoscopic procedures between 2005 and 2018 with neutrophil count taken within 72 hours before the procedure. Post-procedural bacteremia was reported in 103 of the 13,168 patients included (0.8%). In both univariate and multivariate analyses, neutropenia, low albumin level, male gender, older age, preprocedure fever, and admitting department were correlated with increased risk for bacteremia, and a multivariate model incorporating these factors was determined to be predictive of bacteremia. Postendoscopic bacteremia is an uncommon occurrence among inpatients. While the risk factor for bacteremia was found to be neutropenia, it was not higher than the background risk in these patients. Models of bacteremia that are highly predictive have been developed and should be validated.
