Key summary points
Aim To reach consensus on terminology, organisational aspects, and outcome domains of geriatric rehabilitation for older
people living at home.
Findings In three rounds, an international panel reached a consensus regarding the term “home-based geriatric rehabilita tion” to distinguish it from inpatient rehabilitation. The panel also identifed key organisational aspects essential for its implementation and concluded that participation and activity are the primary outcome domains to focus on.
Message The results of this International Delphi shows consensus of experts on various topics in home-based GR, which is important to further develop international collaboration, development and research on this topic.

Abstract
Purpose Internationally, many diferences 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 termi nology, 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 frst 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 defned 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 feld.
