My brother flies EMS and needless to say, some of the flights are undertaken at night or in foul weather. IMHO such flights should be conducted with a suitably equipped aircraft and two crew which could be instrumental in improving EMS statistcs for the obvious reasons. He and probably most pilots would agree, two crew is safer and the aircraft that allow this are probably more suitably equipped.
This of course would require a move away from many single engine EMS ops (and the expensive investment necessary) as in most cases the single engine aircraft cannot accomodate two crew in the EMS configuration. If you want to improve safety though, this is probably a sure bet, just ask the airlines.
