[Functional competence and nursing care in centenarians. The importance of the cognitive status]

The maintenance of autonomy and independence in the oldest old population is at high risk due to the inevitable aging process, which primarily affects functional and cognitive capacities. In this study, we investigate centenarians to assess the extent in which they have lost their ability to live independently. This is done with a classification system for dependency that considers both functional and cognitive limitations and determines the level of functional competence in this population. Based on this system, we evaluate the necessity for nursing care and investigate to which extent their actual needs are covered by the German Long-term Care Insurance. An important and relevant question is whether this system even addresses the evaluation of cognitive impairment. For this reason, 85 centenarians and their proxies were assessed with standardized instruments and the results show a severe loss of independence. The necessity for at least daily contact with nursing care was identified in 91 percent of the centenarians due to their dramatically limited capacities. Forty-four percent of the centenarians need more support than they actually receive from the German Long-term Care Insurance. Therefore, considering cognitive impairment is a crucial component in the evaluation, which would lead to more support by the official system in 20 percent of the centenarians. The considerable differences between the granted and the necessary nursing care demonstrate that co-operation from family members must be heavily relied upon.
