Respiratory failure & ventilation
Occurrence Rate and Outcomes of Weaning Groups According to a Refined Weaning Classification: A Retrospective Observational Study*
Authors' conclusion
The high proportion of "short weaning" patients in this mainly surgical ICU population could be divided into two groups with distinct characteristics.
Study context
- Population
- Mechanically ventilated (MV) patients in a tertiary center with a mixed, mainly surgical ICU population, admitted April 11, 2018 to April 10, 2019
- Participants
- 1,801 patients
- Exposure
- Refined WIND weaning groups: short weaning a vs short weaning b vs difficult vs prolonged vs no weaning
- Outcome
- Weaning group distribution

Main finding
As reported in the abstract
Observational data: associations, not effects.
Further findings

Weaning duration, weaning success, ICU LOS, ICU mortality, hospital LOS, hospital mortality (short weaning a to prolonged weaning)
- Weaning duration, days, median [IQR]
- 0 [0-0] to 14 [10-21]
- Weaning success rate
- 99-69%
- ICU LOS, days
- 2 [1-4] to 28 [19-48]
- ICU mortality
- 1-37%
- Hospital LOS, days
- 10 [7-18] to 48 [27-89]
- Hospital mortality
- 4-42%
- All increasingly worsened from short weaning a to prolonged weaning
- P < 0.01
1-year mortality
- Weaning groups independently associated with 1-year mortality in adjusted analyses
