ROCKVILLE, Md., Jan. 16, 2013 /PRNewswire-USNewswire/ -- When doctors, nurses and other hospital operating room staff follow a written safety checklist to respond when a patient experiences cardiac arrest, severe allergic reaction, bleeding followed by an irregular heart beat or other crisis during surgery, they are nearly 75 percent less likely to miss a critical clinical step, according to a new study funded by the U.S. Department of Health and Human Services' Agency for Healthcare Research and Quality.
While the use of checklists is rapidly becoming a standard of surgical care, the impact of using them during a surgical crisis has been largely untested, according to the study published in the January 17 online and print issue of the New England Journal of Medicine.
"We know that checklists work to improve safety during routine surgery," said AHRQ Director Carolyn M. Clancy, M.D. "Now, we have compelling evidence that checklists also can help surgical teams perform better during surgical emergencies."
Surgical crises are high-risk events that can be life threatening if clinical teams do not respond appropriately. Failure to rescue surgical patients who experience life-threatening complications has been recognized as the biggest source of variability in surgical death rates among hospitals, the study authors noted.For this randomized controlled trial, investigators simulated multiple operating room crises and assessed the ability of 17 operating room teams from three Boston area hospitals – one teaching hospital and two community hospitals – to adhere to life-saving steps for each simulated crisis. In half of the crisis scenarios, operating room teams were provided with evidence-based, written checklists. In the other half of crisis scenarios, the teams worked from memory alone. When a checklist was used during a surgical crisis, teams were able to reduce the chances of missing a life-saving step, such as calling for help within 1 minute of a patient experiencing abnormal heart rhythm, by nearly 75 percent, the researchers said.
