This practicum project investigates current emergency department waiting room models and explores how the psychology of waiting can be applied to positively influence the waiting experience. This culmination of research, coupled with concepts of evidence-based design (EBD), precedent research and regional site visits result in an understanding of emergency department waiting that challenges current emergency department design. This knowledge led to the formulation of a theoretical framework and hypothetical design proposal that aims to uncover, identify, and integrate design concepts known to influence emergency department waiting environment satisfaction.
