Sentinel event alerts are issued periodically by The Joint Commission to identify common or emerging patient safety problems and provide organizations with approaches for addressing these issues. A retained foreign object (RFO)—surgical materials or equipment unintentionally left in a patient's body after completing the operation—is a never event that can have serious clinical consequences. Despite being long recognized as a critical—and preventable—error, RFOs continue to occur, with nearly 800 cases being reported to The Joint Commission between 2005 and 2012. This alert makes several recommendations to help prevent RFOs, including focusing on enhancing the reliability of the traditional manual count of instruments and materials used during a procedure, improving safety culture in the operating room through interventions (e.g., teamwork training), and investigating technological approaches (e.g., bar coding of surgical sponges) to ease identification of potentially missing objects before patients are harmed.

This scientific statement from the American Heart Association (AHA) reviews the current state of knowledge on safety issues in the operating room (OR) and provides detailed recommendations for hospitals to implement to improve safety and patient outcomes. These recommendations include using checklists and formal handoff protocols for every procedure, teamwork training and other approaches to enhance safety culture, applying human factors engineering principles to optimize OR design and minimize fatigue, and taking steps to discourage disruptive behavior by clinicians. AHA scientific statements, which are considered the standard of care for cardiac patients, have traditionally focused on clinical issues, but this article (and an earlier statement on medication error prevention) illustrates the critical importance of ensuring safety in this complex group of patients.
