Health System Benchmarks
Thomson Reuters just released a white paper, “100 Top Hospitals®: Health System Quality/Efficiency Benchmarks Study,” that provides excellent national benchmarks on five clinical and efficiency measures that appear on many health system scorecards:
- Risk-adjusted mortality index
- Risk-adjusted complications index
- Risk-adjusted patient safety index
- Core measures mean percent
- Severity-adjusted average length of stay
Thomson Reuters evaluated the performance of U.S. health systems with at least two short-term general acute-care hospitals plus a few Critical Access Hospitals that passed its exclusion rules. You can access the study online for a complete explanation of the process and results.
