In medical emergency situations, the triage process allows patients in potentially life-threatening condition to receive the fastest and most appropriate medical treatment. Triage consists in an evaluation of patients’ medical condition on a colour-based scale, reflecting from major to minor urgency. Shannon’s entropy measures are applied to such process in order to evaluate concordance, overestimation and underestimation of triage codes assigned to patients in two different moments and by different health-care professionals: during the acceptance phase, by nurses (variable X), and by physicians after deepened diagnostic evaluation (variable Y). Entropy indexes were also used to compare the years 2016 and 2015, showing a little increment of equivocal transmission with respect to year 2015.
