Oh what fun… This is just one of many factors affecting turnover time (TOT).
For the sake of smaller graphs and clarity, I’m showing only the times till anesthesia induces the patient to show the comparison of surgery cut times. The time from anesthesia induction till surgical incision will stay the same, so will not add to the overall decrease.
LEGEND: nurse -> lighter purple anesthesiologist -> green
Here we have a common scenario in which the nurse who is setting up the room also has to wheel the patient from the pre-op holding area to the OR room. This is not including the situation in which the same nurse who sets up the room is also the nurse who does the pre-OR check-in in the pre-op holding area (the cut time would be delayed even longer).
In the first graph, with the nurse doing all the work, the start time for the anesthesiologist would be 9:17 am (last green bar). And–as you can see–the anesthesiologist has a 13.75 minute (6m + 7.5m) slack period between the time he sees the patient in pre-op holding till the time he has to start setting up his anesthesia equipment. That’s plenty of time for a cup of coffee and donut (bathroom break, too).
Now we have a different policy in which the nurse who is setting up the room is different from the nurse who brings the patient from pre-op holding to the OR room. In this scenario, the anesthesia start time is 9:10 am (last green bar)–which is 7 minutes earlier, which means the surgical cut time is 7 minutes earlier, which means turnover time is 7 minutes shorter. The anesthesiologist does not get coffee, nor a donut, nor a bathroom break.
The additional risk from this is that you’ll have a sleepy, hypoglycemic anesthesiologist who is anxious because he needs to use the restroom. It could affect the induction.
