This Report highlights the findings from the 2014 evaluation of interprofessional teamwork among 10 Geriatric Assessment and Intervention Network (GAIN) teams following program expansion. The evaluation included use of a validated, psychometric tool - The Dimensions of Teamwork (DTEAM) tool - developed and implemented by Dr. David P. Ryan (Regional Geriatric Program of Toronto; Ryan & Cott, 1994). The survey had an ~87% response rate, and the Report describes the need for continuing professional development (CPD) in identified areas of interprofessional team practice.
