I was not implying that it was routine. However, I am saying that it has been approved and done to complete routine, elective surgeries in the US. And when the good idea fairy comes a knocking and there is even the smallest amount of precedent to be found it’s amazing what can get approved.
While in residency at BAMC circa 2011-2012, 4 ISO ORs were set up in the parking lot and routine surgeries were performed there to help with surgical load during the OR renovations
Winn ACH, Ft Stewart GA circa 2014-2015. A CSH surgical team was set up in the parking lot (ISO OR, tent pre-op/PACU) to help off set surgical backload. When I questioned the safety and legality of that setup, we were assured by patient safety and facilities that the setup met all OSHA and Joint Commission requirements that the main ORs were held to. I found that hard to believe when I toured the facility and the tent kept flapping in the wind while grass kept blowing through it on the surgical side of the red line. I made it known that the CSH would have to be self sustaining and that the anesthesia department would not be involved in providing care for those cases. The powers that be couldn’t understand why we would be concerned. After all, they were only talking about doing the “easy” quick cases in there, like pediatric T&As

. Myself and the ENTs put the brakes on that ridiculous idea. But they did perform a fair number of procedures (mostly ortho stuff) out there over several months.
