Benchmarking for Level 3 Trauma Centers

I've been searching unsuccessfully for benchmarks for blood use in Level 3 trauma centers. Specifically, I interested in:

1) The amount of wasted blood products related to MTP and emergency release in that setting. 

2) The use of liquid plasma, never frozen vs thawed plasma - does the use of liquid plasma reduce waste?

3) What ratio do you see for RBC/plasma use?

4) What percentage of your MTP/emergency release patients are transferred? (which naturally limits the amount of blood used)
