We'd love to explore the UK but have no clue what's the best way in. Any suggestion?

Perhaps not obvious, but you can expect to need to do localization: https://news.ycombinator.com/item?id=16333599

That might be a place to start, with translation and localization of instructions.

Not sure I can ask at my next nephrology appointment I would suspect approaching individual NHS trusts.

Thanks for the very "heart felt" advice. The hospitals that we have traction all have great champions. Coincidentally we are working with Redox on a few deployment already. I'd love to chat with you more. What's the best way to connect?

Although having a great champion is important, I’m not so sure if that person necessarily has to be a physician at the hospital. Dave Chase touches on this briefly here (I don’t necessarily agree with the title of the article): http://hitconsultant.net/2017/03/30/new-walking-dead-digital...

Just as you are working with colonoscopy centers, working with large medical groups that do a lot of their procedures through surgical centers (pain management, basic ortho stuff), would be a good way to start before working into hospital systems.

Can you PM me on Reddit, /u/z3ugma?
