Ask to speak to the consultant preferably with your father if you are there and if not then your father can give his consent for the consultant to speak to you. If he is confused and can’t consent then family should be involved with his care anyway under the Mental Capacity Act.
Prepare your questions and don’t be afraid to ask for clarification. The how long question is the one we (I’m a consultant) dread if it doesn’t look imminent as we’re usually crap at predicting it, hence all the ‘the doctor only gave me a couple of months and that was 5 years ago’ type stories.
If it doesn’t happen then you can raise it with the Patient Advice and Liaison service (PALS), all Hospitals have one and contact details should be on the hospital website. If you still don’t get what you need write to/email the CEO – the contact details should again be on the hospital website. Making a reasoned fuss on the ward usually helps.
