In order to validate this we need to think about what are we trying to get
as an outcome measure.
Does it identify:-
1.Time
2. Injury
3. need for intervention
I think mostly 3. However, difficult to study unless you had a full response
to everything and then looked at what you did (I think only HEMS London
could do something like this).
A less satisfactory validation (but an achievable one) would be to do the
scoring and then validate it against an expert panel who had access to all
the information.
Patient info
Extracation info
Distances/times/geography.
Any other thoughts?
