Key result
A 3-star composite hospital rating predicted lower risk-adjusted mortality compared to 1-star hospitals for CABG (2.6% vs 5.0%), AVR (4.5% vs 8.5%), and PCI (2.4% vs 4.1%).
Why the study?
Does a novel composite measure of surgical quality better predict future hospital mortality rates compared to individual measures or CMS Hospital Compare ratings in patients undergoing major surgery?
Observational
Yes
Does a novel composite measure of surgical quality better predict future hospital mortality rates compared to individual measures or CMS Hospital Compare ratings in patients undergoing major surgery?
Composite measures of surgical quality combining volume and risk-adjusted mortality are highly effective at predicting future hospital mortality rates for major procedures, outperforming existing CMS ratings.

Novel composite may aid high-risk procedure hospital selection; leaves open prospective validation before changing referrals.
Dimick et al. (2012) conducted an observational in High-risk surgical procedures. 3-star hospital rating vs. 1-star hospital rating was evaluated on Risk-adjusted mortality. A 3-star composite hospital rating predicted lower risk-adjusted mortality compared to 1-star hospitals for CABG (2.6% vs 5.0%), AVR (4.5% vs 8.5%), and PCI (2.4% vs 4.1%).
