Avoiding One and Done

This article presents the development of the Kennedy Model of Sustainability (Kennedy Model), a research-based model of sustainability, and its subsequent application to interprofessional practice and education (IPE) initiatives. The national mixed methods, multiple case study of Geriatric Education Centers that led to the development of the model and resulting four core components of sustainability and related strategies is described. The model is discussed in the context of implementation science and the know-do gap and applied to an IPE initiative and center. Finally, implications for further research are presented including opportunities to incorporate the model as a valuable tool in implementation science. Application of the Kennedy Model to IPE initiatives has provided opportunities for model testing, supporting the model’s core components, and providing additional strategies to foster sustainability of IPE initiatives.
