Statistical models were constructed to assess whether hospital size impacts our ability to identify “true” hospital ranks using data generated by pay-for-performance programs patterned after HQID. We used HQID data from Year 1 and CMS’ Hospital Compare data to address the following questions:

  • How accurately can we expect to identify “true performance scores” for hospitals participating in HQID?
  • What unintended consequences might arise in a system that establishes rewards and penalties based on relative performance when relative performance is measured with substantial variation in accuracy
