Keep the message proportionate
Use the shortest explanation that still tells the truth about the event, impact, and current position. For a message about how to tell family about a new diagnosis, use this factual base: separate symptoms, diagnoses, medication, dates, and clinician advice from assumptions or internet research.
Give timing that can be trusted
Give a realistic date, a simple option, or a direct yes-or-no question and avoid vague promises such as soon. Ask for the record, appointment, review, accommodation, or care decision through the correct channel. Make the immediate next step clear enough that the recipient can answer without reconstructing the entire history.
Close the loop without drama
Do not share another person's medical information or treat a message as a substitute for clinical advice. Contact local emergency or urgent medical services for severe, worsening, or immediately dangerous symptoms. A calm ending is more credible than a warning, a grand gesture, or language designed to provoke a response.
