Elizabeth Casson Memorial Lecture 2020: Re-engineering truth and certainty in occupational therapy.

The Elizabeth Casson Memorial Lecture is awarded on an annual basis to a member of high standing within the occupational therapy profession. The 2020 lecture was delivered by Dr Jenny Preston MBE who contested the underlying assumptions of truth and certainty by considering how we generate, create and understand knowledge within the occupational therapy profession. Through the principles of process re-engineering, Dr Preston sought to define, analyse and identify how we interpret and apply that knowledge within our broad understanding of truth to capture the impact of occupational therapy. Finally, Dr Preston attempted to design and develop a future state in which evidence and practice are entwined to create the best possible outcomes.
