Sounds like this might work to offer it to doctors as a white label phone app or pwa, that each customer (doctor or group or clinic or hospital etc) skins and gives to their own customers or sticks on their own website.
It has the recommendation engine and the doctors marketing looks and some forms of low-friction way to contact the doctor (generate billable service) from email to video chat.
Doctor pays for the startup skinning, any feature changes or updates, and a subscription which pays for ongoing development of the engine and the datasets, maybe some related hosting.
Doctor maybe gives the app to tge users free, maybe charges if they think they can pull it off, and generates sales from the in-app "help me" buttons.
Could have a few quasi-generic versions geared to different kinds of practises that smaller practices could share.
