We actually started moving this way several years ago. It was a big cost to the hospital- we used to flash entire instrument trays for back surgeries, and they ended up having to buy I think 4-5 more sets to prevent the flashing. We also are required to get management permission to flash anything implantable, and that's only if the surgeon absolutely refuses to delay surgery in order for SPD to sterilize it (which takes about 90 minutes from the time they get the set). It's really cut down on the flashing of whole sets. We still occasionally flash contaminated items- most recently, we had a retractor with a screw, and the screw fell on the floor. We got the second retractor, but it was broken, so we ended flashing the screw for the first one.
