Hypothesis

An indigenous flora should exhibit a protective effect against secondary colonization.

Conclusion

Oral administration of a probiotic delayed respiratory tract colonization/infection by P. aeruginosa.

Supporting Evidence

  • The probiotic group had a median delay to P. aeruginosa acquisition of 50 days compared to 11 days in the placebo group.
  • Only 2.9% of patients in the probiotic group developed ventilator-associated pneumonia compared to 7.5% in the placebo group.
  • Probiotic treatment increased the nonacquisition expectancy mean to 77 days.

Takeaway

Giving sick patients probiotics can help keep bad germs away from their lungs for longer.

Methodology

A randomized, double-blind, placebo-controlled pilot study in ICU patients receiving either probiotics or placebo.

Potential Biases

Potential bias due to the non-randomized nature of patient selection and exclusion criteria.

Limitations

The study was a pilot with a small sample size and conducted in a single ICU.

Participant Demographics

Patients aged 18 years or older, with a mean age of 57 years, mostly male.
