I also worked in B2B health SaaS companies. Even then some health systems used whatever you call the hosted Windows servers and people used their computers as dumb terminals to run apps. There were clients for iPads.
This is an option for a lot of things, e.g. we delivered Epic Hyperspace over Citrix, but it can be extremely expensive in terms of TCO to do for every app (we still had over 3,000+ individual on prem hosted apps maintained).
