Abstract
Background The rapid adoption of laparoscopic surgery since the late 1980s added tremendous complexity into the operating room OR environment For each case a plethora of additional equipmentincluding monitors video equipment wiring tubing and cordshad to be set up prolonging OR turnover time and decreasing OR efficiency In 1993 the concept of designated minimally invasive surgery MIS suites was introduced MIS suites integrated monitors and video equipment into the OR on ceilingmounted columns and moved the controls to a centralized nursing station The overall effect of this innovation on OR efficiency has not been measured Methods Five RNs with varying degrees of MIS experience were instructed on video setup and putaway criteria and then timed while performing a set of standardized tasks Each set of tasks was performed twice using a standardized surgery model Differences in setup and putaway times between MIS suites and standard ORs were tested using the ttest for paired comparisons Results The mean ± standard deviation SD video setup times were 279 ± 53 sec MIS and 2543 ± 540 sec standard the putaway times were 198 ± 27 sec MIS and 2223 ± 260 sec standard The mean difference ± standard error SE in both the setup 2264 ± 169 sec p = 00001 and putaway times 2025 ± 86 p = 00001 were large and statistically significant Conclusion Using a simulation model we have demonstrated that the use of a MIS suite reduces video setup and putaway time significantly with the potential for significant associated cost savings This provides just one justification for the high cost of building such ORs of the future
