ANSI/AAMI ST79:2006: 10.3.2 states: "...The length of time that records must be retained varies throughout the country. Each health care facility is responsible for determining its record-retention policy based on state and local regulations, legal considerations (e.g. statutes of limitation for lawsuits) and its individual situation.""
