Seems to be working for me. I did a bit of training in the area and we are encouraged to talk to service users about advance care directives and wills. I've generally found that a direct approach is best. I think its unfortunate that a stigma surrounds discussion of death. In a lot of ways, I've found that people are actually very open to discussing it and often welcome it.
If that isn't the case as happens in some situations, you find out soon enough. Also as a part of making any kind of residential placement, these issues have to be discussed as there is an expectation by CSCI that a care plan in the home will specify preferred funeral arrangements in particular.
Training is useful because we still need to challenge our own perceptions of death and fear of death.
If I were to advise Skills for Care (and i am inabsolutely no position to do so as I'm sure people with a lot more experience than me are involved there!) I'd say that the important thing is for the practitioner to be able to discuss death honestly and openly without euphemism or trying to skirt around the issue.
I would say that it can take training to develop this confidence but having a discussion about death with someone can enrich the therapeutic relationship. It just has to be done with sensitivity.
It is also an area where perceptions of religion and spirituality and different cultural attitudes needs to be extensively considered - as these rituals of life and death are enormously important culturally.
