Youth corrections staff is still a whole other story than doctors though. A physical examination is probably one of the most vulnerable positions one could be in. These cameras would record people getting naked, multiple orifices being examined, and patients talking about symptoms or things they are unsure and often ashamed about.
The cost would be enormous. I imagine many people would be even more reluctant to go to the doctor than they are now.
And the benefit, in my opinion, would be very slim. Medical malpractice is far more subtle than the examples from the article. As patients we’re rarely worried that our doctor will physically assault us, we’re worried about errors in judgement, delays in care, and prejudices based on gender, ethnicity, age, sexuality, and so on. And those aren’t directly observable most of the time. Even if you get the moment on camera where your doctor decides to trivialize your symptoms you mostly wouldn’t be able to prove it happened for discriminatory reasons.
