As far as I can tell this is a demo EMS from Intersystems, they provide Cache [1] to companies developing real EMS with modern user interfaces. They don't sell this product in the USA (so not to upset their customers), but have dumped it on the rest of the English speaking world.
I suspect here is some sort of NDA with those unfortunate Hospitals taking this pile of stinking £%^£" as I have never found a user group or trustworthy review.
I get to use it at ground level (talk about poor UI), at management level (no coherent db integrity, very poor reporting) and have seen a complete inability to reconfigure the system to cope with COVID.
When ever we see demos for new clinical system I always ask "Would those coding this system accept this level of quality/usability in their daily software tools?". The marketing guys look at me like I'm from another planet.
I know "you get what you pay for", but for something hundreds of thousands of Hospital staff will be using for patient care (we don't bill in the UK), there should be a floor below which no company should offer half-baked dangerous products. Trakcare is in the sub-basement.
