Abstract
Patient safety has assumed a prominent role on the policy agenda since the Institute of Medicine reportTo Err Is Humanwas released in November 1999. The report maintained that medical error is the predominant mechanism by which patients in the United States and around the world are injured. This finding, along with the report’s recommendation for a “systems” approach to reducing medical error, provided an extremely important insight into the operation of our medical delivery system. Clearly, while advances in medical technology, diagnostic techniques, and knowledge provide the foundation for saving lives, medical error has resulted in their loss. However, recognition that medical error is a primary cause of these avoidable patient injuries and deaths is a key one and may result in improvements within our system of health-care delivery as well as minimization of the emotional and financial toll that iatrogenic injury causes.
