I think we've only had 1 IV started on the last 50 calls and the physician/nurse never complained about us not starting one. However, many of our calls have a minimal transport time, so there simply isn't an opportunity. The only drug we give IV is D50W, so our IVs are mostly for fluid resuscitation and as a precaution (as with nitro administration). For that matter, we don't really start an IV on a medical pt very often.
