Who Is Behind This Website?
Cal Hospital Compare is a performance reporting initiative managed by a multi-stakeholder Board of Directors, with representatives from hospitals, purchasers, health plans, and consumer groups. Prior to 2016, Cal Hospital Compare was known as the California Hospital Assessment Task Force (CHART). CHART was first established in 2004 for the purposes of developing a statewide hospital performance reporting system using a multi-stakeholder collaborative process. CHART aggregated data from participating hospitals until 2011, when its Board of Directors moved to using only publicly available data sources for all hospitals, not just those participating voluntarily. CHART, and now Cal Hospital Compare, are supported by a generous grant from the California Healthcare Foundation (CHCF).
To produce the information on this website, we partner with these respected entities:
- California Healthcare Performance Information System (CHPI)
- Consumer Reports Health
- Truven Health Analytics
For details on the roles each partner plays, see the Data Sources & Ratings pages.
Cal Hospital Compare History
Public information about health care quality is hard to come by, sometimes not objective, and often difficult to understand. Early on the California Health Care Foundation (CHCF) saw an overwhelming need to make such information available and recognized that providing the information online is the most effective path.
- In 2002, CHCF first began publishing ratings of nursing homes online at the site “California Nursing Home Search” (CalNHS.org). In December 2004, CHCF added similar profiles and ratings of home health care agencies and hospice services. And in September 2005 the site was expanded to include congregate living health facilities, assisted living, continuing care retirement communities, adult day health care programs, and adult day care centers.
- Around that time, CHCF also embarked on a new effort to report on the quality of care in California hospitals; however, not much data existed. So hospitals and insurers agreed to voluntarily start collecting key data on medical outcomes. In 2007, CHCF began aggregating the new data with existing sources and launched CalHospitalCompare.org to provide performance report cards for participating hospitals.
- In 2009, CHCF launched CalQualityCare.org, upgrading and updating the California Nursing Home Search site based on in-depth research conducted among key audiences, including consumers and long term care providers.
- In 2014, CHCF combined all these resources into one unified place — at CalQualityCare.org.
- In October 2016, CHCF transitioned ownership of the hospital portion of CalQualityCare.org to a multi-stakeholder, non-profit entity, Cal Hospital Compare.
Cal Hospital Compare will continue updating data and ratings as new information becomes available.
