Thank you @helenelizabeth. I’ll describe a little about the project and if anyone has suggestions please contact me. We are wanting to support a population health program in Washington State that involves diabetes and mental health. Most of it should be standard CHT fare except for three things. First is being in the US under HIPAA regs. That will mean beefing up the access control, encryption and hosting as determined by a risk assessment. It also will mean that we will need to find a way of encrypting some SMS content, if we use that. And, for reasons I can explain another time, I think we will want to use SMS, so I will need a discussion here about options. Connection to two separate covered entities (medical and behavioral) with separate EPIC systems argues for a FHIR interface, probably through a FHIR server. The good news is that the sponsors want to build something that works, not just buy something that sort of works. So we should be able to stage the development. If there are any users out there with experience with any of these requirements, I would love to pick their brains and share.
