How did IHI calculate lives saved for the 100,000 Lives Campaign?
Hospitals participating in the Campaign were required to submit monthly raw mortality data (deaths and discharges) to IHI for both the entire Campaign period (January 2005 – June 2006) and the 18 months prior (July 2003 – December 2004). The Campaign calculated the “lives saved” contribution by a particular hospital for a particular month in the Campaign period by comparing that hospital’s data for that month to that hospital’s data for that month in the baseline period, with a national patient mortality risk adjustment applied to account for the overall change in patient acuity between baseline and Campaign periods. The sum of all these individual hospital months of lives saved over all months and all participating hospitals yielded the overall Campaign total lives saved. Note that the baseline period was always 2004; Campaign period months in 2006 were still compared to that month in 2004, not 2005.
