There's a playground, but I have no more power there than I do in my own production environment except that I can write an order like "all-unicorn diet" and nobody would see it. I don't know precisely what you mean by Epic-PLY and "developer sandbox"; I'm an end-user, not a developer. Other than knowing some of the IT team and being the local point of contact, I'm no different from any other anesthesiologist in terms of control. What I would like is a sandbox where I can do anything, figure out what's possible, and then report to the team the things I've found and ask if it would be possible to put them in production. Maybe yes, maybe no, but we live and die by the status board (if you ever get involved with EMR and anesthesia, a good status board is the most critical piece of infrastructure). And I can't even share mine with others.

Draconian institutional policies are indeed an issue. WiFi calling is blocked, despite the fact that a significant part of our first floor has zero cell signal.

If you get bored, PM me and we'll set up a time where I can show you some samples. I'll need a few days to sanitize them of identifiable info.
