I am a firm believer in assisted dying although only in very limited circumstances, say where death is on the horizon within 6 months.
The Harold Shipman case took away some of the informal practices about giving too much morphine which were common in the past and has led to the under-medication of dying patients.
Brilliant palliative care is possible. My husband had the offer, a few weeks towards the end, of going into a hospice and I literally bit their hand off to take the opportunity as I saw how time-poor and busy the district nurses were and how pain meds were delayed because of problems with prescriptions and then delivering them, and I feared for his pain at the end. The hospice was the most amazing place and gently he died there, with no pain, no anxiety and 24 hour care. It was the fitting death for an amazing person and I'm glad we were able to give him that, I'm so sorry for those who had to suffer along with their loved ones. I've also had experience of home hospice with syringe drivers and the full palliative care options and that worked well as well. Relying on district nurses/GPs is grim.
I would like the option of assisted dying. So did my husband and it was a big source of worry that he wasn't able to know he had that option. In the end, we didn't need it, but it would have been a source of comfort to know, had things become unbearable, that it would have been possible.
I think dementia is a special case and very difficult to legislate around because by the time the person is so ill that assisted dying might be invoked, they have almost always lost capacity. I don't think we should stop ploughing ahead though with assisted dying for terminally ill people because of the dementia case though.
I am for assisted dying and better palliative care, they are not exclusive.
