CMS - "In the interest of promoting high-quality, patient-centered care and accountability, the Centers for Medicare & Medicaid Services (CMS) and Hospital Quality Alliance (HQA) began publicly reporting 30-day mortality measures for acute myocardial infarction (AMI) and heart failure (HF) in June 2007 and for pneumonia (PN) in June 2008. CMS has since expanded the publicly reported outcome measures to include 30-day readmission for these conditions, complications and readmission data for hip/knee replacements as well as in-hospital adverse events and mortality. Publicly reporting these measures increases the transparency of hospital care, provides useful information for consumers choosing care, and assists hospitals in their quality improvement efforts. CMS annually calculates the following categories of outcome measures based on claims and administrative data for public reporting:

30-day risk-standardized mortality measures 

  • Acute Myocardial Infarction
  • Heart Failure
  • Pneumonia

30-day risk-standardized readmission measures

  • Acute Myocardial Infarction
  • Heart Failure
  • Pneumonia
  • Hip/Knee

AHRQ Patient Safety Indicators (PSIs)

  • PSI 04 - Death among surgical inpatients with serious treatable complications
  • PSI 90 Composite - Complication/patient safety for selected indicators"
