Effect of early vs late tracheostomy placement on survival in patients receiving mechanical ventilation: the TracMan randomized trial.
JAMA, 2013 · Multicenter randomized trial
What the trial found
30.8% versus 31.5%; no significant difference. Many deferred patients did not undergo tracheostomy.
Clinical interpretation
No routine early survival benefit; prediction of prolonged ventilation is imperfect. Neutrality does not prove subgroup equivalence.
