The Research Agenda Setting Process is a joint endeavor by the American Geriatrics Society and the Hartford Foundation to increase geriatric expertise in the surgical and related specialties. This article provides the results of the Research Agenda Setting Process project on research needs in geriatric rehabilitation, which included a systematic review of the literature and a group consensus process. Explicit research questions and methodologies were developed for three cross-cutting research needs in geriatric rehabilitation and for the rehabilitation of eight specific conditions affecting older individuals.
