There is a professional code of conduct which guides medical staff. There is also a problem sometimes when medical staff are communicating with patients that they may use clinical, academic or scientific phrases. Whilst these are readily understood by their peers and colleagues they may only serve to confuse, and perhaps cause anxiety in the lay person. It seems a sensible idea to remind medical staff to be clear in what they are saying and use commonly understood language. Things like 'you are short-sighted' instead of 'you have myopia'.
