Not even close. 2014
Over the three years studied, total ICU occupancy ranged from 57.4% to 82.1% and the number of beds filled with mechanically ventilated patients ranged from 20.7% to 38.9%. There was no change in occupancy across years and no increase in occupancy during influenza seasons. Mean hourly occupancy across ICUs was 68.2% SD ± 21.3, and was substantially higher in ICUs with fewer beds (mean 75.8% (± 16.5) for 5–14 beds versus 60.9% (± 22.1) for 20+ beds, P = 0.001), and in academic hospitals (78.7% (± 15.9) versus 65.3% (± 21.3) for community not-for profit hospitals, P < 0.001). More than half (53.6%) of ICUs had 4+ beds available more than half the time. The mean percentage of ICU patients receiving mechanical ventilation in any given hour was 39.5% (± 15.2), and a mean of 29.0% (± 15.9) of ICU beds were filled with a patient on a ventilator.
