A few months ago my brother, who had terminal cancer, went into hospital for an operation to improve the quality of his life. The operation apparently went well but DB suffered appalling neglect during his stay in hospital, to the extent that he came out much sicker than he went in, never recovered, and died five weeks later.
I wrote a letter of complaint on behalf of the family about his treatment, and the hospital carried out an investigation. I was expecting a half-hearted "we're sorry and will do better in future" kind of reply, but actually the hospital have denied everything. To be honest, the letter was mainly a way of getting it off our chests and we didn't expect great things, but the fact that they are saying they did nothing wrong has really got my back up.
To be clear: we knew his cancer was terminal, but our position was that he wasn't particularly ill when he went into hospital, and that his neglect sent him into a downward spiral and caused him to die much earlier than he otherwise would have (I should add he was aware of this as he declined and was highly pissed off about it).
My SIL is talking about legal action, but really, is there any point in pursuing this? Is there anything else we can get out of them? The one person who could contradict their statement is not here any more (as they must be aware), and an apology isn't going to bring him back. Following it up would be stressful with no guarantee of success. Is it better to let it go?
