Yeah, UCSF here also uses MyChart, and I agree that it's great from the perspective of the power and flexibility it offers me, even if the UX isn't fantastic (frankly, I think it's fine, though could be better).
But, like you, I've also observed medical staff inputting my data during a visit, and it looks terrible, and I've also noticed significant UI changes on occasion. (I've gone in once a month for the past two years for an allergy immunotherapy injection, so I get to see it regularly, and over time.) I've only heard the nurses complain once or twice, but I can kinda tell how they occasionally stumble with the UI, and it all just seems completely unavoidably bad. A little user research would go a long way, but I imagine the cost of switching to another system (if there even are that many good options) is so high that a hospital might ignore staff complaints anyway, so the company is not incentivized to spend time and money to make things better.
