Sepsis is underreported in Swedish intensive care units: a retrospective observational multicentre study.

This large Swedish multi-centre study showed that 28% of adult ICU patients fulfilled the Sepsis-3 criteria, but only one-third of them had sepsis according to ICU discharge codes. We could confirm our hypothesis, that sepsis is severely under-reported in Swedish ICUs, and we conclude that discharge codes should not be used for quality control or research purposes.
