These authors used cross-sectional data from Medicare Hospital Compare on three mortality and three readmission outcome measures to compare each provider in the top or bottom performance tier with those in the middle tier. They found that better-than-average and worse-than-average hospitals may not significantly differ from average hospitals. Their analyses illustrate the need for further innovations in quality measurement approaches used in public report cards so that consumers and other audiences can accurately distinguish between higher- and lower-quality providers.

2. "Statistical benchmarks for health care provider performance assessment: a comparison of standard approaches to a hierarchical Bayesian histogram-based method."

Paddock SM.
Health Services Research 2014 June; 49(3):1056-73.
PUBMED link:

The author compares histogram-based statistical benchmarking to other more widely used statistical benchmarking methods to demonstrate whether and how their performance differs, both in terms of setting a performance benchmark and also in terms of which providers are identified as exceeding the performance benchmark. Her study uses publicly available data from 3,240 hospitals on two process-of-care measures.
