SBTs Shifted Care From Intuition To Protocol
- The 1996 NEJM SBT study standardized screening, a 2-hour trial, and provider notification to reduce ventilation duration.
- That protocolized approach shifted care from variable physician judgment to reliable, evidence-based processes.
Screen, Trial, And Notify Promptly
- Use objective SBT screening criteria and a defined trial (e.g., 2 hours) to decide readiness to extubate.
- Notify the responsible provider promptly when a patient passes the SBT to reduce delays in extubation.
Early Liberation Reduced Vent Days
- The original trial produced earlier liberation from ventilation with no increase in reintubation.
- Early extubation reduced prolonged ventilation and shortened weaning time in randomized patients.
