I've just been going through this with my mum, who is 78. She has multiple health conditions and is in care (on the same road as where I live). She was in and out of hospital most of last year with infections, her quality of life just getting worse and worse. On top of everything else, she had developed a heart condition, which required a pacemaker. On balance, we'd agreed (with mum's agreement) to minimize any interventions, as she was finding the repeat hospital admissions and invasive procedures increasingly distressing. However, in early December, she had an 'abdominal' crisis and was on the point of dying. She pulled through the emergency and it was then agreed that if she did have a pacemaker, it would help markedly with her other conditions. The heart thing had been underlying for quite some time. So, she had it done and is recovering- her first ever surgery, actually. The nurses'/ transport strikes didn't affect things too much and I'm so grateful for the good care she had. The pacemaker was really done as a palliative measure, to relieve her other symptoms and, so far, it seems to have been worth it, although we are not expecting miracles.
My mum probably would not fare well with anything more invasive and probably wouldn't want it. Her sister is 80, also with various health conditions but she and her husband have a zest for life and I would argue that they have every right to enjoy it for as long as they can. They've certainly contributed enough, as did my mum. My aunt's 87 year old friend had recent abdominal surgery and would put many 60 years olds to shame with her community involvement and active lifestyle. I have another 80 year old friend (much older than me) who has so much to offer. I'm friendly with another 81 year old who has been offered a kidney transplant. She wasn't going to have it because she felt it should be prioritized for a younger person. However, she is still very active, again, with her family and in her community.
In summary, I think it should be a case-by-case analysis, in terms of how much to intervene with an older person. One 80 year old can be very unlike another, in terms of disposition and well-being. I see some poor, dementia-riddled souls in mum's care home and it is, eventually a mercy when they die. In my late dad's case 14 years ago (stroke survivor/ COPD), the clinicians did over-intervene and prolonged the final year of his life unnecessarily. He had a horrible death. With the pressures of the NHS as it is, there might not necessarily be the time to assess a person holistically. Life, in itself, isn't 'fair' and younger people die despite the very best of interventions. There's never going to be a perfect solution but, having seen the apocalyptic scenes in our local A & E multiple times and what the nursing staff endure, I fully support the nurses' strike. Most of the time I have been there, it has often been younger people filling the corridors and cubicles, many off their heads on drink and drugs. What do we do about those?
