Insights into emergency physicians' minds in the seconds before and into a patient encounter

Clinical reasoning is a core competency in medical practice. No study has explored clinical reasoning occurring before a clinical encounter, when physicians obtain preliminary information about the patient, and during the first seconds of the observation phase. This paper aims to understand what happens in emergency physicians' minds when they acquire initial information about a patient, and when they first meet a patient. The authors carried out in-depth interviews based on the video recordings of emergency situations filmed in an "own-point-of-view-perspective". 15 expert emergency physicians were interviewed between 2011 and 2012. Researchers analysed data using an interpretive approach based on thematic analysis and constant comparison. Almost all participants used a few critical pieces of information to generate hypotheses even before they actually met the patient. Pre-encounter hypotheses played a key role in the ensuing encounter by directing initial data gathering. Initial data, collected within the first few seconds of the encounter, included the patient's position on the stretcher, the way they had been prepared, their facial expression, their breathing, and their skin colour. Physicians also rapidly appraised the seriousness of the patient's overall condition, which determined their initial goals, i.e. initiating emergency treatment or pursuing the diagnostic investigation. The study brings new insights on what happens at the very beginning of the encounter between emergency physicians and patients. The results obtained from an innovative methodological approach open avenues for the development of clinical reasoning in learners.
