Effectiveness of new sedation and rehabilitation methods for critically ill patients receiving mechanical ventilation.

Retrospective, single emergency department, before-after comparison, not randomised. Only patients who reacquired walking ability at discharge were included, so it says nothing about patients who died, had poor neurological prognosis, or could not walk. The intervention changed several things at once, including sedation vacation, propofol with dexmedetomidine, default wheelchair orders, nurse-therapist collaboration, and seven-day therapy, so the contribution of any single component cannot be separated. The paper reports many outcomes and does not state a single primary outcome, so some significant findings may be among multiple comparisons. The text and outcome table differ on whether time to walking was significant; the table did not mark it. The paper did not validate standard criteria for release from the emergency department or hospital. APACHE II scores were worse 24 hours after admission, so baseline illness severity may not be reflected accurately.

Do not conclude that sedation vacation alone or physical therapy alone caused the shorter stays. The study changed sedation vacation, propofol with dexmedetomidine, default wheelchair orders, nurse-therapist collaboration, and seven-day rehab together, and it was retrospective and single-site.
