Development and evidence base of a new efficient assessment instrument for international use by nurses in community settings with older people.

In a world where 12% of the population, and 22% of that of more developed regions, will be older than 65 years by 2030, new targeted programs and social protections will be needed for older people in many countries. As economic and human resources become more scarce, efficient instruments are needed to realize sustainable health care for these large populations of older subjects. To address this need a new assessment instrument was developed. The core of the instrument consists of focused geriatric assessment by a health or social care practitioner working in primary or community care, most often a nurse. The assessment data result in an efficiently targeted care and welfare action plan based on the patients' priorities. This instrument was initially developed, tested and spread within Europe, and then in validation studies across all WHO regions of the world. Because of the urgent societal questions on quality and sustainability of primary health care, especially for older people, we briefly review and summarize the development and evidence base of the instrument, which was called EASY-Care Standard. In a series of studies across many populations it proved to have high acceptability, reliability, validity and cost-effectiveness. Therefore, EASY-Care has great potential as a universal tool for global use in promoting independence in old age, and can make an important contribution to the quality and sustainability of health and social care in our aging societies.
