In the 1970s, when a National Institutes of Health (NIH) study of ARDS was being planned, the estimated annual frequency was 75 cases per 100,000 population. Subsequent studies, before the development of the AECC definitions, reported much lower figures. For example, a study from Utah showed an estimated incidence of 4.8-8.3 cases per 100,000 population.

On the basis of these statistics, it is estimated that 190,600 cases exist in the United States annually and that these cases are associated with 74,500 deaths.

However, a more recent single-center study compared the incidence of ARDS and found the rate decreased from 82.4 to 38.9 cases per 100,000 person-years from 2001 to 2008. [7] This decline was attributed to the fall in hospital-acquired ARDS since there was no change in the incidence of admission with ARDS.
