Interdisciplinary teams consisting of a variety of health professionals working toward common patient goals have become an important innovation in clinical practice. In many parts of the world interdisciplinary teams have become part of practice, including in geriatrics. However, many gaps and the need for further empirical research and translation into practice remain. This is particularly true for the discipline of psychology, as much of the extant literature in engagement, training and practice in geriatric settings or educational settings does not include psychologists. Many advances in interprofessional teams, in acute settings in particular, do not include psychologists as part of the team. With respect to training, educating trainee health professionals, including psychologists, in interdisciplinary practice has still not become a standard part of training curricula internationally. Several excellent models of interprofessional and interdisciplinary training, including international models of interdisciplinary team competencies, have been developed. However, both the empirical testing of these models and their implementation in educational and practice settings is lacking. Within the geriatric healthcare context, the evidence base for both interprofessional care and the need for enhanced training models incorporating interprofessional skills is evolving, and further research on efficacy in evolving clinical contexts and translation into educational contexts worldwide is required. Ultimately, psychology must increase its presence within both interprofessional research and applied contexts.
