I worked in Intel's Digital Health Group for a few years and my experience was that anything involving hospitals will be slower and take longer than you think. I can't possibly imagine a customer facing trial happening without a face to face meeting and some training. Lots of people can say no - the CFO, the CEO, the CMO, CIO, the head of nursing - and none can completely say yes. Granted, this market has changed a lot in the years since I left it, and it is getting more nimble, but be prepared for a drawn out process. And I'd budget for some plane tickets.
