Assessment of an Automated Telesurveillance System on Serious Falls Prevention in an Elderly Suffering From Dementia Specialized Care Unit: the URCC

2 URCC in the Limousin region will be equipped with the automated telesurveillance system. Patient will be selected by ward's geriatrician and randomized into two groups after informed consent. One group will have cameras installed and the other will not and will act as a comparison group. Patient will be assessed twice during the study, at admission in (inclusion visit) and at outcome from the URCC (end of study visit). Each assessment implies a standard geriatric assessment, a fall questionnaire, a Neuropsychiatric inventory for behavioral disturbances and a quality of life questionnaire (EQ5D). Every fall will be considered as adverse events and will therefore be listed along the study and characterized in types and number.
