I worked in many different sizes and types of facilities, from 3 OR county hospitals, to major metro teaching hospitals to a private 2 OR surgery center, and about everything in between. (I wasn't a "job hopper" ~ I worked as a "temp" or Traveling Tech for several years, in addition to some stints as a regular full or part timer.)
A 30 minute turn over at any of them would have been a luxury. But, it depends on where you are, what kind of cases you do, and what sort of turnover help you have.
One nice mid-range facility I temped at had a button on the wall inside each OR. When your case was over, and your patient ready to be moved, you rang the bell the same number of times as your room number. Turn over/housekeeping staff was waiting at your door to come in and move your patient, clean the room and set it up for the next case. Frequently any equipment you would need for your next case was waiting outside your door too, and brought in when the room was clean.
They had quite a training program to learn what was what, where to put it, and how it all got handled! Nursing went with the patient out to PACU, and then to PreOp to take charge of the next patient, or if there were 2 RNs (usually) 1 came back to help get the room opened and going for the next case.
Surgical Techs took care of getting instrumentation down to the dirty room, take a potty break as needed, pick up the next case cart and bring it in to open. (That is if someone hadn't beaten you to it, and was already opening the room by the time you got back to it!)
The RN not bringing the patient was helping to open the room and do counts, while the other RN brought the patient. It worked beautifully, nobody stressed, and we were always well under 30 minutes at the same time. When my time was up covering for a couple of maternity leaves, I really hated to leave! Everyone was friendly, and we all helped out each other.
Another place, there were a couple of docs always up our behinds for "FASTER FASTER!" turnovers. One had a habit of standing in the doorway and looking at the clock and patting his foot while watching us do all the work (grinning, of course.) Of course he was also frequently in the way. I broke him of it when I started handing him the mop, or a full trash bag to take out and down the hall. When he figured out that I was always going to put him to work if he continued to stand there, he began making himself scarce between cases! We also never had over 20 minute turn over times.
There are lots of other stories, but it all boils down to who's in charge and whether or not they have your back or are only interested in kissing someone elses's ass while protecting their own at your expense. Employee and patient safety should always be #1 on the Hit Parade!
Unfortunately, the almighty $ is what rules the game these days. Your only protection is to have each others' backs, and help out whenever and wherever you can. And the #1 rule in Healthcare is "Document document document!" If 30 minute turnovers are impossible to do safely, then make sure they know why! Find out where the process is failing you, and have brainstorming sessions on how to fix it. Try out what makes sense, and can be done safely, and if it works, incorporate it into your routine. (The "you" being collective here ~ not individual.) If not, throw it out and try something else. For instance: If you have to run all over hell and gone for supplies everytime the room gets turned over, figure out how to make turnover packs, or have a cabinet arranged to have all those supplies in one place. Linens, disposable trash/linen bags, suction cannisters and tubing and anesthesia circuits, and whatever else you use to change out the room. There's all kinds of ways to consolidate work. You have to figure out what works best for you. Good luck!
