Today I came across this news article. In short, the Academy of Medical Royal Colleges (in the UK) is providing new guidelines to medical doctors on the writing of clinical letters to patients. Among the advices is "use English instead of Latin". The article (and the official document) only mentions one example, which is using “twice daily” instead of “bd” (bis die) for medication indications.
Having the privilege of living in the UK for 7 years, I never encountered any such uses of Latin in my interactions with GPs. Are you aware of further examples in which Latin is used? I'm curious.
