Factors associated with 30‐ and 90‐day mortality in intubations among critically ill patients
Authors' conclusion
Cardiovascular and respiratory instability were associated with increased 30- and 90-day mortality. Presence of an attending anesthesiologist was associated with a better survival following intubation outside operating room.
