Human Factors

We seek to understand and to optimize the interactions between healthcare providers and their working environments in order to facilitate safe behaviour and ultimately promote patient safety. We consider the physical, built environment, as well as the cognitive and social environments. Taking a systems perspective to quality improvement, we recognize that modifications in any area of the work domain will have repercussions in other areas.

Implementation Research

In the constant stride to introduce evidence-based practice, many interventions fail to introduce meaningful improvements in patient care outcomes. We seek to understand the factors that help or hinder implementation of such practices in order to effectively inform future quality improvement efforts.
