Respiratory failure & ventilation

Low Tidal Volume Ventilation Is Poorly Implemented for Patients in North American and United Kingdom ICUs Using Electronic Health Records

ChestPublished Retrospective cohort study

Authors' conclusion

There has been limited implementation of LTVV in routine clinical practice in the United Kingdom and the United States. VT > 8 mL/kg PBW was associated with worse patient outcomes.

Study context

Population
Patients mechanically ventilated for > 48 h in UK and US ICUs
Participants
5,466 vs 7,384
Exposure
Factors associated with adherence to low tidal volume ventilation
  • CCHICn = 5,466
  • eICU-CRDn = 7,384
Outcome
Factors associated with adherence to LTVV (median VT > 8 mL/kg PBW)

Main finding

As reported in the abstract

Median VT and risk of median VT > 8 mL/kg PBW
Risk of median VT > 8 mL/kg PBW
Odds ratio (95% CI)
BMI > 30 kg/m² (CCHIC)
1.9(1.7–2.13)
BMI > 30 kg/m² (eICU-CRD)
1.61(1.49–1.75)
Female (CCHIC)
2.39(2.16–2.65)
Female (eICU-CRD)
2.29(2.26–2.31)

Observational data: associations, not effects.

Further findings

30-day mortality, median VT < 8 mL/kg PBW

Cause-specific HR (95% CI)
VT < 8 mL/kg PBW (CCHIC)0.86 (0.76–0.97)
VT < 8 mL/kg PBW (eICU-CRD)0.9 (0.86–1.00)

VT over time

Significant reduction in VT over time in CCHIC
