On surgical disruption: rating, expected operative time or actual wasted time - some comments on Gillepsie et al (2012)

The effect of intraoperative disruptions on surgery time has attracted increasing attention over the past decade. The focus of the majority of related studies is descriptive: in other words, the frequency of disruptions that occur in operating rooms (ORs) and their nature is recorded. Few studies have analysed the effect of these events on surgery time or the root sources of these events. The paper by Gillespie et al1 is a nice attempt to refill this gap in the literature by assessing frequency and type of disruptive events
