Question normal

Before EHRs with decision support, IBM Watson, and apps that process patient data, physicians combined patient data with an open source body of medical knowledge. Open source medicine meaning peer-reviewable, easy to modify by an individual physician, able to be freely taught to other physicians, and regulated at the "edge" of practice through professional licensure and credentialing.

Now, as medicine (defined as the combination of patient data with medical knowledge) moves into mostly secret software in EHRs, and apps, that requires centralized regulation by vendors and bureaucracies, physicians are losing control of the profession's core tools. Is the use of secret software really a benefit to either the medical profession or our patients?

Where does the profession draw the line and self-police ourselves into using only peer-reviewable open source software?
