Ascension Columbia St Marys Hospital Milwaukee vs Mercy Health System Corp

7 measures are reported by both. Ascension Columbia St Marys Hospital Milwaukee is ahead on 4 of them, with 2 measures level or without a stated direction.

“Ahead” means better on a measure whose direction the publishing agency states. Where the agency states no direction, neither column wins — a bigger number is not automatically a better one, and deciding otherwise here would be this site inventing a finding.
