Perhaps I'm in the minority, but I don't think emojis should be used at all in health records… It reminds me of stories my mum would tell me about when she would get a résumé pre-digital, and there would be a mark/symbol on it, and it might meant the person is fat, black, wears glasses, etc...
I don't think you're in the minority, and even if you (we) are, you are still correct.
