Write about people positively. Think about inclusive language. Know how the people you are writing for like to describe themselves. Check if there are descriptions that are not suitable. There are NICE guidelines here to help you with many dos and dont’s for healthcare professionals. Refresh your knowledge. Remember - conditions describe what a person has, not what a person is.
Stick to straightforward language. We all appreciate simpler, clearer writing. It saves our time and energy. We can concentrate on the message.
If you need to use clinical or technical terms give a lay term or clear definitions alongside them, for example ‘difficulty swallowing (dysphagia)’.
Keep asking yourself - is there a shorter or simpler way to say what I need to?
