When it comes to care, I've always been concerned with the reality on the ground rather than with the theory. If paid carers all performed the personal hygiene aspects of their job satisfactorily, then of course it would be unnecessary, and arguably ridiculous, for family members to always be present to assist the carers to ensure the job gets done properly.
Sadly, though, the fact that someone is being paid to do a particular job is no guarantee of the standard to which they will do it, and in the case of personal care on vulnerable bed-bound adults, where surely no chances should be taken, it helps to ensure the long term wellbeing of the patient if a family member can be present to lead or assist. I personally know of two cases (friends of the family for many decades) where the care of a bed-bound person was left by the family largely in the hands of visiting carers, and, sadly, both people developed pressure sores that ended their lives. Both Waverleyone and I have also testified to our own disappointing experience of some carers' standards.
I did hope it would be sufficiently clear (evidently it wasn't) from my whole line of approach to Waverleyone that I was acknowledging the fact that always being present to assist at carer visits is not possible for everyone and might not be achievable for him and his family. It was precisely in order to obtain clarity from him on this matter that I wrote what I did in post #33:
It's a solution that works very well for us...but it does require either me or my wife or another family member to do the dirty part of the job, i.e. the wiping, cleaning, and disposal of waste after the job is done. In order to ensure that your mother's hygiene is assured, would you and other family members be prepared to roll your sleeves up and do what you find the carers reluctant to do?
