Recruitment Details

Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
45 out of 165 Hospital Corporation of America (HCA) hospitals were recruited for this trial of adult ICUs. There was a 12-month baseline period from January 1 through December 31, 2009; a phase-in period from January 1 through April 7, 2010; and an 18-month intervention period from April 8, 2010 through September 30, 2011.

Pre-Assignment Details

Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
74,256 patients were involved in the intervention period among adult ICUs from the 43 participating hospitals. Routinely collected information for about 48,390 individuals cared for during the baseline period was used for comparison to the experience of the patients in all three arms of the Intervention period.
