International Delphi study on terminology, organisation and outcomes of geriatric rehabilitation for older people living at home

PURPOSE: Internationally, many differences are observed regarding the practice of geriatric rehabilitation for older people living at home. To improve international collaboration and research on this topic, we aimed to reach a consensus on terminology, organisational aspects, and outcome domains to focus on.

METHODS: We conducted a three-round online Delphi study among 60 (Home-based) geriatric rehabilitation experts from 14 countries. In the first round, we collected diverse perspectives and input through statements and questions. In the subsequent rounds, participants rated statements on a 5-point Likert scale. Each statement could be accompanied by written feedback. After each round, results were presented anonymously to the participants, and statements on which no consensus was reached were rephrased. Consensus was defined as 70% or more participants (fully) agreeing with a statement.

RESULTS: Sixty, 52, and 46 experts completed rounds 1, 2 and 3, respectively. After two rounds, we reached a consensus on ten statements and on the remaining four in the last round. A consensus was reached on the terminology used (i.e., home-based geriatric rehabilitation) and on several organisational aspects (e.g., essential aspects to consider for starting home-based geriatric rehabilitation and the importance of a knowledgeable case manager). Lastly, experts agreed that participation and activity are the most important outcome domains to focus on.

CONCLUSIONS: Through an international Delphi study, we reached consensus on various important aspects of home-based geriatric rehabilitation. These outcomes provide a basis for further development of this emerging field.
