• A recent observational study was published looking at the ICU incidence and outcome of ARDS
• This international prospective cohort study looked at 459 ICUs and over 29,000 patients
• Incidence: 10.4% met ARDS criteria
• Severe ARDS occurred in 23.4%
• Clinical recognition of mild ARDS was only 51%
• Less than 2/3rds of patients with ARDS received a TV of 8 mL/kg or less
• Prone positioning was used in 16% of patients with severe ARDS
• Recognition of ARDS was associated with higher PEEP, greater use of neuromuscular blockers, and prone positioning
• Mortality ranged from 35% to 46%
• Pneumonia was the biggest risk factor for ARDS
