Dr. David Matchar, Profesor & Dir. Program in Health Services and System Research Duke-NUS Medical School, Singapore

A hallmark of successful aging is a sustained ability to fully interact with the world late into the life course. A core objective of aging research is to understand the factors that impact functional ability and to inform personal, clinical and public policy decisions that promote successful aging for individuals and populations.

The WHO has illustrated this goal by describing a series of desirable trajectories of functional ability. However, there is no current causal model to explain what produces these prototypical life course trajectories.

Dr. Matchar will discuss a parsimonious dynamic simulation model developed in Vensim that can recreate a wide variety of trajectories for functional ability described by the WHO. Because the model is based on explicit, testable hypotheses about causal relationships, it promotes the generation and testing of improved hypotheses about the determinants of functional trajectories both in the short- and long-term, and the identification of potential interventions to optimize that trajectory based on underlying drivers of functional loss or recovery at the individual level.
