Since the advent of intensive care in the mid-twentieth century, there have been debates about how the intensive care unit (ICU) should be organized and managed. Indeed, the ICU can be considered an organizational intervention. The sickest hospitalized patients are grouped into a single space, in part so they can benefit from the expertise of experienced nurses, physicians, and ancillary staff members. It stands to reason that understanding the organization of the ICU, particularly who should work in the ICU and how frequently they should work there, is critically important.
