The Health Quality Council of Alberta recently released a framework which is intended to be a guiding document to support the planning and evaluation of healthcare environment mock-ups from which an improved design process can result. It was developed in collaboration with many international experts and stakeholders. Specifically, it outlines a systematic way to collect and analyze data from full scale mock-ups through the use of simulation, where individuals enact processes and procedures that will be performed in the space. This presentation will provide an overview of the evaluation methodology. Identifying and addressing design issues early in the design process will likely yield financial returns, improved patient safety, and could prevent decades of inconveniences.
