We don't usually draw from PICC's either. I think our docs wait too long to make the decision to put a PICC in and then it's too late because event the antecubitals are shot. We have a lot of old people who generally don't have veins to start with....

We have been using midlines a lot more for peripheral access and having good success with them. The lumens on the PICC's just seem like they are too small to draw blood through without clotting it or damaging the line. But, hey what do I know? Our facility is usually about 10 years behind the times anyway....
