For our pre-analytic, we measure if they answer the PAT questions correctly (ie, no PAT samples answered as not pregnant for scheduled c-sections), rejected samples collected by pt care areas, rejected samples collected by lab, and TAT for plasma prepared to made ready for ER. For analytic, we measure ER plasma from time of order to transfusion time and wasted/expired products. For post-analytic we measure uncrossmatched/trauma forms being returned and completed with corerct info, transfusion reactions, transfusion reaction completed consults, verbal orders/readbacks and giving units a final dispositon. I hope that is helpful. I am curious to see what others are doing as well.
