We conducted a scoping study to examine how interprofessional health care teams improve the outcomes of older adults experiencing cognitive challenges. We searched Ovid, Medline 1946, and MEDLINE In-Process and other non-indexed citations, using the concepts multi or interdisciplinary care teams, confusion or cognitive impairment, and elderly adults. Of 4,554 articles the review yielded, 34 relevant to our inquiry, using Arksey and O’Malley’s methodological framework. Twenty-nine per cent of authors reported on the processes interprofessional teams use to achieve positive outcomes for older adults. They highlighted the importance of communication, staff strategies, and education interventions in achieving outcomes with older adults and in supporting interprofessional collaboration. The review revealed knowledge gaps about the processes teams use to collaborate in caring for older adults experiencing cognitive challenges, and how to best incorporate older adults and their families’ perspectives in team decisions. More research to understand processes interprofessional teams use is needed.
