I forget exactly where I read this, maybe here. It's an increased communication between the doc and the patient, all done through the net, as the patient can both consult and make notes in his records, same for the doc. It does many positive things, but pertinent to my idea of devil's advocate, it improves quality of care through reduction of errors, detectable by both the doc and the patient. So here devil's advocate, by contradicting the doc, would go through the doc's orders and ultimately find the errors as well, and maybe even more efficiently since he would be an equally proficient doc.
