HIPAA

Only if personally identifiable information was made available. My understanding is that this was not the case here. Doctors are allowed to discuss medical cases, just not in an identifiable way.

Not if the patient consented. My first job out of college was filming procedures in the OR for a private plastic surgeon for his educational YouTube. They had to sign a waiver beforehand though. All perfectly legal she lost her licence because malpractice not specifically streaming. The guy I worked for was legit af (top 5 facial surgeon in the world) and would’ve told me to stop filming it something ever went wrong, not that it ever did.
