The only thing really surprising about this is the lack of discretion in uploading media.
Between Grey's Anatomy and Scrubs, the recent Covid social media stupidity, and the increasingly casual work culture (in the US at least), there's little surprise that doctors are becoming less professional. Adding tiktok just increases narcissism or attention-seeking.
There are a couple of TLC shows following medical professionals (podiatric surgeons and a couple of dermatologists). The thing they have going for them is that they have show directors and editors to highlight "good" surgical practice for content.
