Care Directions (a great site for advice for older people on the cusp of needing care, and their families) is conducting an anonymised survey on behalf of a supplier seeking views of public and professionals on the physical and ethical acceptability of a telecare bracelet for people with dementia. Do participate in this survey (you may win a £50 voucher) and refer it on to other people if you can.
