Meaningful Use has been evolving since its inception in 2011, and Stage 3 is the third phase of the electronic health system incentive program. Meaningful Use Stage 3 (MU3) is optional in 2017, but will be mandatory for all participants in 2018. In this episode of The Cerner Podcast, Sandy Summers, Director of Meaningful Use at Dignity Health, talks through preparing her organization for MU3.
