The functional status and utilization of care of elderly people living at home

A postal questionnaire was used to obtain information on the functional status of and the utilization of care by elderly people living at home. The aim of the questionnaire was to enable the investigators to select elderly people for a further interview to identify the factors that lead to a demand for professional care. The questionnaire provided relevant information as to the prevalence of physical limitations in elderly people and their use of professional and informal care. The information obtained was reliable and valid as is shown by comparison with information given in subsequent interviews. It appears that the prevalence of limitations was of the same size as that found in other studies, both national and international. The more limitations, the higher the proportion of professional care utilization. The factors "use of informal care" and "not living alone" were inversely related to the utilization of professional care. The amount of informal care provided was very high among elderly people with handicaps. Rather than being a substitute, it seems that informal care is a condition for professional home care to be successful. The postal questionnaire appeared to be an efficient means of investigating the functional status of and utilization of care by elderly people living at home. As such it could be used for planning and allocation of home care.
