Abstract
The objectives of this study were to identify the frequency and nature of flow disruptions in the operating room with respect to three cardiac surgical team members: anaesthetists; circulating nurses; and perfusionists. Data collected from 15 cases and coded using a human factors taxonomy identified 878 disruptions. Significant differences wereidentified in frequency relative to discipline type. Circulating nurses experienced more coordination disruptions (χ(2) (2, N=110)=7.136, p<0.028) and interruptions (χ(2) (2, N=427)=29.743, p=0.001) than anaesthetists andperfusionists, whereas anaesthetists and perfusionists experienced more layout issues than circulating nurses (χ(2) (2, N=153)=48.558, p=0.001). Time to resolve disruptions also varied among disciplines (λ (12, 878)=5.186, p=0.000). Although most investigations take a one-size fits all approach in addressing disruptions to flow, this study demonstrates that targeted interventions must focus on differences with respect to individual role.
