That is NOT a stupid question at all! But nope, not true at all.
There are so many things going on when a severely unwell person is admitted to intensive care, you don’t go “oh they are a donor - Bob upstairs needs a heart, let’s take this one!”. Here’s an example of an organ donation case:
John (he’s pretend) has a bleed on his brain. Intubated and ventilated by paramedics at the scene because he’s completely unresponsive and unable to breathe. Gets admitted to A&E. Scan shows this is a very severe injury to his brain and it is likely he will not recover, however there is emergency surgery that can be done to give him a slight chance. He is rushed to surgery. Then onto ICU. His blood pressure and ventilator requirements etc are all over the place, it takes hours and much medication to stabilise him. Finally when he is semi stable (yet still critically unwell and unlikely to survive / get to a point where he and his family will be happy with his quality of life) conversations are had about where we go from here (this could be days - a few weeks later!). He’s not making any effort to breathe for himself and he is not responding despite not being on any sedation / drugs that keep him asleep. Family say he would not want to live in a disabled or reliant state. Organ donation is not mentioned at this point at all. Family spend time with him whilst in the background we check if he is on the register. If he is then we contact the specialist organ donation nurses to approach the family and tell them that he is and ask their opinions about going forward with donation. They are not forced into this at all, and are given the opportunity to ask a million questions about the process. If he isn’t on the register then we still contact the specialist organ donation nurses to inform them that we have a patient who is heading towards the end of their life and is a candidate for donation. They then approach the family to ask their opinion - ONLY when the time is right (after they have had time to come to terms with the discussions they have had / spent time with the patient etc). If they do not want to donate, the ventilator and medication sustaining life is removed and the patient passes away with his family around him. If they do want to proceed with donation then the specialist nurses do many further specialist tests on the patient to ascertain if he can donate. The family are made aware of all of this beforehand and have to sign consent forms. The results of all the tests are then sent to a central donation hub where the patients organs are matched to people who are waiting for organs. His heart may be matched to someone in Glasgow, his lungs to someone in London and his liver to someone in Newcastle for example. It’s all anonymous and it does take up to maybe 12 hours or so to get all the tests and matches done. During this time the patient is often unstable so the team fight really hard to keep them “alive” as the organs need to be viable. So definitely not being given up on. Once all of his organs (or the ones that are usable anyway) have been matched and then accepted by the receipt, he is prepared for the operating theatre. This is a massive task in itself. The hospital receiving each organ send their own specialist surgeon and team to retrieve the organ, so many surgical teams travel to the patient for the operation. The family say goodbye to the patient, taking handprints and locks of hair etc if they wish, and then the operation is carried out with such care. The organs then travel to their destination straight away. The family of the patient are contacted the next day by the specialist nurses and for a few months afterwards. They are also offered counselling and bereavement care.
It is such a special and heartwarming process to be involved in. Yes it is incredibly sad, but seeing people act so selflessly during their very worst hours is humbling.
I hope some of that made sense and didn’t offend - upset / bore anyone. I really don’t want people being put off / I want people to know the truth.
