I'm curious how systems rotate through fresh whole blood and justify the relative high volume of loss. I can certainly see the potential benefit, but things like HEMS not included I would think those systems that would have the greatest benefit (rural systems with long transports) would also have pretty high product waste.
We have entertained the idea a couple of times in our system but even at our our sister level 1 when they looked at uncrossed transfusions there still isn't enough volume to justify implementation (granted here there are way too many trauma centers in the state). We are also very limited with what we can do with the blood afterwards as we cannot use it for routine inpatient administration, priming bypass, and so on; and once you pass the initial resuscitation the value of whole blood over lab guided resuscitation (Pt/INR, TEG, hemogram, lytes, etc) quickly wanes. Our primary and specialty teams teams are BCT, I don't think there is any really push towards FWB currently.
I wonder what percentage of services that carry blood product actually use a warmer, it seems like a battle to get smaller centers to use them consistently in the ED and even in larger trauma centers it doesn't seem to be a priority outside of the ED and OR. I remember it was quite the battle on our department to even keep fluid bags warmed and that cost was minimal.
I would hope that any service that carries blood would also carry an iStat or similar device so that you can look at your pH and electrolytes and treat accordingly. We test our blood before priming our bypass and ECMO circuits and it is amazing how not compatabile with life stored blood can be.
