The only MD / MBA I know is the CMO of a large outpatient multispeciality group. Not really sure what her job entails, but she was the head of our scribe program (she preferred to be hands on on her projects). During our meetings, she always talked about some new idea that she was pushing into clinic that would improve efficiency, billing, physician QoL, etc. and often quoted the success of other medical systems nationally for her rationale to try these programs within our own system.
Her last big idea that she was interested in was some form of AI program to help with charting.
