Projected incidence of mechanical ventilation in Ontario to 2026: Preparing for the aging baby boomers.
OBJECTIVE
The aging baby boomers are expected to have a significant impact on the healthcare system. Mechanical ventilation is an age-dependent, costly, and relatively nondiscretionary medical service that may be particularly affected by the aging population. We forecast the future incidence of mechanical ventilation to the year 2026 to understand the impact of aging baby boomers on critical care resources.


METHODS
Population-based, sex-specific, and age-specific mechanical ventilation incidences for adults for the year 2000 were directly standardized to population projections to estimate the incidence of mechanical ventilation, in 5-yr intervals, from 2006 to 2026. Sensitivity analyses were performed by varying population projections and mechanical ventilation incidence for the elderly.


METHODS
Province of Ontario, Canada.


METHODS
Noncardiac surgery, mechanically ventilated adults.


METHODS
None.


RESULTS
The projected number of ventilated patients in 2026 was 34,478, representing an 80% increase from 2000. The crude incidence increased 31%, from 222 to 291 per 100,000 adults. The annually compounded projected growth rate during this 26-yr period was 2.3%, similar to the actual growth rate experienced in the 1990s. The projected incidence was relatively insensitive to changes in assumptions, with estimates for 2026 ranging from 31,473 to 36,313 ventilated adults.


CONCLUSIONS
The incidence of mechanical ventilation projected to the year 2026 will steadily increase and outpace population growth as occurred in the 1990s. In the current environment in which intensive care unit resources are limited and ventilated patients already use a significant proportion of acute care resources, planning for this continued growth is necessary. Existing evidence-based strategies that improve both the efficiency and efficacy of critical care services should be carefully evaluated for widespread implementation.
