However, despite those ongoing protocols, the effectiveness of those safety strategies is still unknown.Wrong site surgery can cause extremely bad outcomes, which may range from performing surgery on the wrong side of the body and delayed the necessary treatments to amputating the wrong leg then the patient is suffering both physically and psychologically. In order to improve better outcomes and prevent those preventable surgical mistakes, an extended surgical timeout (STO), also called second time out was implanted into the health care system. This dissertation discusses the effectiveness of the extended STO out based on evidence from research and case studies, and it also explores the interventions used to reduce risks of wrong site surgery. This dissertation also analyzes patient who is allergic to epinephrine and how extended surgical time out improved their quality of care.The article, The extended surgical time-out: does it improve quality and prevent wrong-site surgery? focuses on pediatric surgery and review the results of the implementation of an extended surgical time out. The members of Harbor-UCLA Medical Centre implemented extended surgical time out beginning January 2006. The protocol included confirming a patient’s ID, anesthetic, and technical details, medications administered and the available ones and the need for special equipment and blood products (Lee, 2010). The impacts of implementing surgical timeout were then studied before induction of anesthesia and surveys of both before and after implementing the pre-induction STO were recorded. The results of this study showed that there were no significant differences in elapsed time to incision for both urgent and elective operations and after implementing pre-induction surgical timeout (Lee, 2010).
