Not sure what a network in medical context is but here in Canada there is the option of medical assistance in dying (MAID).

Dad considered it but as a Catholic and just as a choice by anyone it was even more terrifying than just a natural death. You have to make the active choice and I think that is what scared him. Plus at the time I wasn't really seeing the anxiety he had he was good at masking it.

He died in palliative care with assistance for any pain which was more mental than physical.
