Hospital Compare

Hospital Compare is a consumer-oriented website that provides information on how well hospitals provide recommended care to their patients. This information can help consumers make informed decisions about health care. Hospital Compare allows consumers to select multiple hospitals and directly compare performance measure information related to heart attack, heart failure, pneumonia, surgery and other conditions. These results are organized by:
• Patient Survey Results
• Timely and Effective Care
• Readmissions, Complications, and Deaths
• Use of Medical Imaging
• Linking Quality to Payment
• Medicare Volume

Hospital Compare was created through the efforts of Medicare and the Hospital Quality Alliance. The Hospital Quality Alliance (HQA): Improving Care Through Information was created in December 2002.HQA was a public-private collaboration established in December 2002 to promote reporting on hospital quality of care. HQA consisted of organizations that represented consumers, hospitals, doctors, employers, accrediting organizations, and federal agencies. The HQA effort was intended to make it easier for consumers to make informed health care decisions and to support efforts to improve quality in U.S. hospitals. Since it's inception, many new measures and topics have been displayed in the site.  

In 2005, the first set of 10 "core" process of care measures were displayed on such topics as heart attack, heart failure, pneumonia.and surgical care.  

In March 2008, data from the  Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey, also known as the CAHPS Hospital Survey, was added to Hospital Compare. HCAHPS provides a standardized instrument and data collection methodology for measuring patient's perspectives on hospital care.  Also in 2008, data on hospital 30-day mortality for heart attack and heart failure was displayed.  Later in 2008, mortality rates for pneumonia was added.  

In 2009, CMS added data on hospital outpatient facilities, which included outpatient imaging efficiency data as well as emergency department and surgical process of care measures.  

2010 saw the addition of 30-day readmission measures for heart attack, heart failure,and pneumonia patients. 

This year, in 2012, we added data on the CMS readmission reduction program and measures that were voluntarily submitted by hospitals participating the American College of Surgeons  National Surgical Quality Improvement Program.  The three measures are:

  • Lower Extremity Bypass surgical outcomes
  • Outcomes in Surgeries for Patients 65 Years of Age or Older
  • Colon Surgery Outcomes

Hospital Compare continues to evolve, and in 2013 will include data on the new Hospital Value Based Purchasing program.
