I can understand the medical profession's initial skepticism re: malpractice, but I think malpractice is for cases of malicious intent, not "accidents", so they should be more comforted I hope (plus we patients sign releases).
I admit that my thinking came from recent news coverage; a patient reported a very reputable medical practice to the news because she found a camera in her exam room and was concerned about it, and they made a story of it. I felt bad for the medical practice because they had to explain & convince that the camera was disabled during her visit, that the reason it was there as a permanent fixture was because they're a teaching institution, and some things are recorded for educational purposes, especially during Covid when student access to medical facilities had to be limited; they further explained that there would be standard consent forms patients would sign in advance if they agreed to being recorded or having a student present during an exam. I felt bad that the complaint sounded like finding a camera in a department store dressing room.
That is what made me think "Why not?" Just hand the patient (or his representative) the remote control and tell them if they're comfortable with it, feel free to turn the camera on. But phrasing it as a black box is brilliant. Today we really need to keep medical costs down; lowering injuries & medical spending while improving efficiency & employee morale helps the medical system be profitable, and savings are passed down to patients through reduced medical premiums and better medical outcomes!
