While I don't share the specific problem the general thing in chapter 3 of doctors basically treating you like an idiot who needs to super justify every little thing and every curiosity the doctor has regardless of relevance to convince them to do their jobs is super relatable. I guess doctors being assholes like that is more universal than I would have liked to think. :(
At least when Kazuki went into the OR they didn't come face to face with a dozen medical students staring at their exposed body. One horrific invasion I experienced last time I needed a surgery that they thankfully didn't. Wonder if it's less common in other countries, or if they might even do the sane thing and require patient consent before letting in a bunch of kids to be an audience in your most vulnerable moments
(And that's before we get to the "audience participation" that is very common in America but I can't talk about that without feeling sick)
That's really fucked up, I'm in the US too and it's a total violation of medical ethics. Something like this would be beyond the pale at my local big training hospital: any time I've gone there, they've always explicitly asked for consent when bringing in a medical student or getting a recording for training students during my appointment. Even for basic treatment, I've needed to sign a form that has detailed stuff like "we are a teaching hospital and conduct research on excess patient samples, you have the right refuse to consent to this and still get treatment" and "you have the right to ask for the names and positions of all people involved in your care", and I assume a surgical form would be even more involved about whether students may possibly assist.
The American Medical Association explicitly says that "all physicians share an obligation to ensure that patients are aware that medical students may participate in their care and have the opportunity to decline care from students" AMA Code of Medical Ethics - Medical Student Involvement in Patient Care. You are allowed to ask and confirm whether students are involved in your care in any capacity, and if any doctor ever gives you shit for it you can whip this page out. And if you ever get lookers-on again, you can whip this one out, because that's also an ethics violation.
