(HealthDay News) – Typical operating room distractions and interruptions (ORDIs) potentially increase the likelihood of surgical errors among surgical trainees, according to a study published in the November issue of the Archives of Surgery.
Robin L. Feuerbacher, PhD, from Oregon State University in Corvallis, and colleagues assessed whether realistic ORDIs induce errors in a simulated surgical procedure performed by 18 second-year, third-year, and research-year surgical residents. During the critical stages of a simulated laparoscopic cholecystectomy, four distractions and two interruptions were simulated, based on nine months of observations. The participants were assigned a prospective memory task prior to the simulated procedure.
The researchers found that major surgical errors were committed in 44% of simulated procedures with ORDIs (all of which occurred after 1 pm) and 6% of procedures without ORDIs (P=0.02), with the most errors caused by interrupting questions, followed by sidebar conversations. Fifty-six percent of those with ORDIs forgot the prospective memory task, compared with 22% of those without ORDIs (P=0.04).
“This study provided statistically significant evidence to support the hypothesis that realistic ORDIs increase the likelihood of errors in a simulated laboratory setting with novice surgeons,” the authors write.
