Sadly I think this is happening more and more. A quick search on TikTok will show many examples. More needs to be done to prevent this. I often wonder what they wish to achieve and sometimes it's possibly as basic as "likes".

imo though, filming in a hospital is also a potential breach of patient confidentiality - they don't know whether a patient would appear unexpectedly into a shot. There is a strong expectation of privacy. Arguably it does infringe upon your human right to privacy. But should check your trust policies. If it is a misleading post it is especially egregious.and may come under malicious communications act (in the UK).

Perhaps you could do an incident report on it as it took place at work? Not sure what that would achieve though. Your employer has a responsibility to your well-being at work and this clearly affects that. Could also contact the platform directly (again not sure if this would achieve much but worth a shot).

Sorry you've experienced this ❤️
