Odd notice on the wall in Civic Center Station downtown. Anyone know context for this?
Web sites about it, per the poster itself, here and here. It looks like there's more detail about this "PROPPR" study here.
Looks like it's saying that if you get carried into San Francisco General Hospital unconscious and bleeding massively, they might choose the mix of blood products for your transfusion in a way that advances a medical study, and worry later about getting your consent or the consent of someone acting for you. Which might be fine because "Both ratios [of blood products] are in widespread clinical use in the United States." I'm no medical expert. It might all be fine. Just, odd. Never seen anything like this in a subway station.
Here's the poster (click to enlarge).
