Mechanical ventilation is a common therapy used in caring for critically ill patients, but its epidemiology is poorly understood. We describe population-based, temporal trends in the incidence, survival, and hospital bed utilization of mechanically ventilated, noncardiac surgery adult patients.
Retrospective, observational cohort study using linked administrative databases.
Province of Ontario, Canada.
Subjects were 150,755 unique patients who received mechanical ventilation between 1992 and 2000.
None.
Annual measures of mechanical ventilation incidence, 30-day patient mortality rate, and number of mechanical ventilation days and inpatient days for mechanically ventilated patients as a proportion of total adult inpatient bed days.
From 1992 to 2000, the crude and age- and gender-adjusted incidence of mechanical ventilation increased 9% (p 80 yrs (2.3, 2.2-2.3), Charlson score 3+ (2.0, 2.0-2.1), and specific diagnosis. From 1992 to 2000, the number of mechanical ventilation days and inpatient days for mechanically ventilated patients, as a proportion of total adult inpatient bed days, increased 69% and 30% (both p
