Gerry Humphris is one of a team of researchers from Social Dimensions of Health that comprise the Scottish Clinical Interactions Project (SCIP). This project seeks to use recent developments in information technology to establish a unique longitudinal dataset of routine digitally audio-recorded consultations within primary care. This would provide one of the largest and most detailed insights into real world medical consultations in the world.
