On studying ageism in long-term care: a systematic review of the literature.

Background: Ageism in long-term care is pervasive, but it is not easy to define, to identify and to fight it in practice. These difficulties could be overcome if we develop research capable to conceptualize, detect, measure, and understand the multidimensionality and complexity of ageism. Nevertheless, to achieve this, it is fundamental to know how ageism in long-term care has been previously studied.
