> A 2012 review [1] in the journal Current Opinion in Critical Care found that the U.S. has 20 to 31.7 ICU beds per 100,000 people compared to 13.5 in Canada, 7.9 in Japan and between 3.5 and 7.4 in the U.K. Differences in how countries define “ICU” account for some of the disparity, the article notes, and the U.S. needs more ICU beds because it has a higher incidence of chronic conditions like heart disease.
