ICU sedation, delirium & recovery

Early reduction in gut microbiota diversity in critically ill patients is associated with mortality

Ann Intensive CarePublished Prospective observational cohort study

Authors' conclusion

Gut microbiota diversity decreased over time, associated with increased mortality. Fecal pH is an unreliable marker of gut microbiota change.

Study context

Population
Critically ill ICU patients
Participants
96 patients
Outcome
Association between time-varying changes in gut microbiota diversity (Shannon index) and mortality
Follow-up
60 days
Methodological detailsBayesian joint models

Shannon index decrease and hazard of death

Hazard of death per point decrease in Shannon index (fold increase)

1.99

95% CrI 1.04 to 4.51

Daily Shannon index change (mean)

−0.1 points

95% CrI −0.20 to −0.10

Deaths during follow-up

24 of 96

Observational data: associations, not effects.

Further findings
