The OSM is just an ad-qual for UK medics who have zero remote experience. A paramedic in the UK has no experience in remote operations.
Where as Canadian, American, South African and Australian could simply by the nature of the geographic area they work in. No where in the UK is really remote enough to give exposure like offshore.
And then CMT1 don't have the primary care or clinical exposure as a HCPC Paramedic.
But, the OSM seems to miss the mark quite a bit in terms of filling gaps. It's hard to say how to bring both HCPS and CMT1 into a joined discipline for offshore across the globe.
And of course your have the unfortunate result that some who are neither a CMT1 or HCPC Para get on the course and have a cert which represents a certain level of standing.
But the OSM only applies to UK based operations, anywhere else all you need is a good clinical background in remote medicine, perhaps thats worth greater consideration then a 2 week course.. perhaps not.
