The paramedics at the roadside are at the sharpest end of resuscitation skills spectrum.
Whereas the medical staff in A&E have more broadly based skills, and their day to day work involves a lot of stuff is unrelated to any trauma or resuscitation work - eg like fishing out stuff that small kids shove up their noses.

The circs around every death in the department is also carefully scrutinised. The processes of appraisal and reappraisal of protocols never ends. All new ideas/ recommendations are then pooled nationally - and then internationally.
And the protocol for Road Traffic Accidents is the same as it was decades ago ie .....
