Fig. 2From: How many operating rooms are needed to manage non-elective surgical cases? A Monte Carlo simulation studyThis graph shows wait times (median and 95th percentile) according to the number of operating rooms (ORs) for emergency patients and for all patients combined. Wait times increased exponentially as the number of ORs decreased. The error bars are (±) one standard deviation; unseen error bars are contained within the corresponding symbol. When 1 or 2 ORs were used we show only the wait time for emergency patients because simulations generated surgical demand (total surgical time for all patients) that exceeded capacity which thereby resulted in some simulated urgent patients not being treatedBack to article page
