Hey SAR - i think we are at cross purposes....
My question was exactly that - what study has been done re: night operations because I'd posed the question that as charities with finite resources it would be sensible to show that you can do more good with the expansion of the service this way - than (for example) just running more of the same in the daytime.
I asked that question because it seemed that one service was pushing forward with 24hrs ops and yet when one asks for the rational there doesn't seem to be much coming back.
As for my data I am talking about the published accounts for these charities and frankly it the charity called the Air Ambulance Service seems to offer poor value for the people who are contributing.
The last set of accounts suggest they spent £453K on office expenses - who knows the detail but actually given there is an Air Ambulance association those involved can't really just sit back and wash their hands of it.
The first thing this association should do is make a standardised template for the accounts so that it is easy and transparant for people to make accurate read-across.
I'm sure those at the coal face do great things but sadly it is too easy for everyone to pull the "just think of the lives we save" card out, whilst at the same time turning a blind eye.
