I used to do it in Chemistry when I worked in Canada- but that was a 1500-bed capacity hospital, so autoverifying makes sense but, for a smaller facility, manual verification should be fine. The computer screen turns yellow if there's a delta flag, it will turn red if there's a critical value and the normals will just auto-transmit but you have to check your worklist every now and then if some of the normals didn't go through- probably due to computer glitches (which is rare) but otherwise it's a pretty convenient thing for a large facility.
