California requires the reporting of unusual occurrences which threaten the welfare, safety, or health of patients. Legislation was enacted in 2006 to codify reporting of adverse events, operative as of July 1, 2007.  The legislation requires information about reported events and the outcome of investigations or inspections of substantiated adverse events to be made readily accessible to consumers by January 2009 and posted on the state department of health service’s Website and available in written form by January 2015.
