Surgeons under stress make more mistakes in the operating room, study finds

The findings could lead to the development of protocol aimed at reducing acute or short-term stress on surgeons working in the operating room.

During stressful moments in the operating room, surgeons make up to 66 percent more mistakes on patients, new findings from Columbia University show. And since clinical quality is increasingly tied to reimbursement under the value-based structure, such errors have the potential to eat into an institution's brand reputation and bottom line.

Using a technology that captured the electrical activity of a surgeon's heart, researchers found that during intervals of short-term stress, which can be triggered by a negative thought or a loud noise in the operating room, surgeons are much more prone to make mistakes that can cause bleeding, torn tissue or burns.

The results could lead to the development of protocol aimed at reducing acute or short-term stress on surgeons working in the operating room.

IMPACT

Medical errors cause between 250,000-440,000 deaths annually in the U.S., with a sizeable enough chunk of those mistakes occurring in operating rooms. Any change in common practice that reduces the number of mistakes made by surgeons due to stress would also reduce the number of deaths.

The study's lead author, Peter Dupont Grantcharov, is a master's student at the Data Science Institute at Columbia University. A year-and-a-half ago, Grantcharov had the idea to ask Dr. Homero Rivas, associate professor of surgery at Stanford Medical Center, to wear a Hexoskin Smart Shirt under his scrubs while he did surgeries.

The shirt, designed to give athletes precise physiological data during workouts, measures the electrical impulses that trigger heartbeats. From this data, Grantcharov derived heart-rate variability statistics -- the variation in times between heartbeats -- to determine Rivas's momentary stress levels.

Grantcharov was also allowed in the operating room, where he collected laparoscopic video recordings of Rivas as he worked. Another researcher later reviewed the recordings and documented Rivas's mistakes using validated frameworks for assessing surgical performance.

Both his stress levels and surgical errors were time stamped so that Grantcharov could correlate the two. This data yielded the somewhat alarming finding that the effect of short-term stress on surgical error is as high as a 66 percent increase.

THE TREND

A Loyola Medicine study earlier this fall demonstrated that an educational curriculum for physicians in training improves their emotional intelligence, which may help protect against burnout. Before and after completing the educational intervention, doctors took a test measuring their emotional intelligence and significant increases in scores for emotional intelligence, stress management and overall wellness were found at the end.

Teaching emotional intelligence skills "may improve stress management skills, promote wellness and prevent burnout in resident physicians," the researchers wrote.

THEIR TAKE

"I was surprised by that, as well as by the amount of distractions in the operating room," said Grantcharov, who did the study while working as a research assistant at the Stanford Medical Center before enrolling at DSI.

"Many machines have alarms that go off periodically, equipment malfunctions, side conversations take place, people walk in and out of the OR -- I could go on. My hope is that other researchers will build upon our work to make further strides in learning about the causes of stress on surgical personnel. If our study helps make the OR a safer place for patients, I'd be thrilled."
