Study results on contaminated duodenoscopes and correlating attack rates

In 2015, a drug resistant Kl. pneumoniae (MRKP) outbreak at the University Medical Center Utrecht in the Netherlands was linked to 2 contaminated duodenoscopes.¹

In this webinar, Prof. Frank Vleggaar shares the results of the investigation conducted to pinpoint potential contamination factors. He also discusses the opportunities for corrective actions in the short and long term.

This is the first study in Europe assessing the attack rate* of a contaminated duodenoscope.

^{*Attack rate: an incidence proportion, rather than a true rate, that is used to measure the frequency of new cases of a disease or condition in a specific population during a limited period. It is usually used to describe the proportion of the population that develops a disease or condition during an outbreak.}
