Given the interest in the planned storyline on Eastenders about one of the character's liver disease, I want to draw attention to an episode of the US Medical Soap "Grey's Anatomy". Series 11 episode 18 (available on Amazon Prime and maybe other places) was about the shooting of two brothers who were police officers shot during a bank robbery, and the possible organ donation decision having to be made by their mother. Not perfect but an interesting exploration of an often missed element in the process.
Too late to share with the wider community, I think, but I do see TV representations, however flawed, as being opportunities to raise issues against a background of interest but falling availability of organs.
