I'm all for this "MAID" method, as regards to people who, for whatever reason, are in constant pain or have a condition where their quality of life has been significantly reduced. It's a dignified way to go imo.
The details do seem to be a bit sketchy on that report as RD said but if it's true that the war veteran, who was making good recovery regarding their PTSD, was offered death as a way out, then that is tragic. That discussion with the war veteran should never have came about.
It alludes to "better practices and training" to be put in place....no f**king kidding! Better practices and training doesn't necessarily stop stupid though.
If a careworker hasn't got the common sense to appreciate that brooching that subject with a recovering patient is inappropriate as you can get, then they need to get out of the care sector!
As regards to rolling this "MAID" method out for anyone who is simply a bit fed up with their life and wants to end it, then you'd need to go down the route of intense therapy and psychological treatment first because that suggests to me that all is not well with their mental health.
