Dementia and work load evaluation of the elderly.

Dementia and work load were estimated in 4736 elderly home-nursed or institutionalized persons. Mental status was estimated by means of the Clinical Dementia Rating scale (CDR), and work load by means of a traditional work load scale. Approximately one third of elderly over 85 years were living in an institution. 4.6% of the population over 65 years of age were moderately to severely and 1.8% mildly demented. Work load increased with increasing dementia. In homes for the aged 40% and in nursing homes 85% of the residents create a heavy work load. 14.5% of the estimated population are considered misplaced, the majority of whom should be transferred to a higher care level. Dementias cause a major problem on every care level. Services which are lacking for this group and necessary rehabilitation facilities should be provided.
