A method of determining a triage disposition for a person includes providing a plurality of triage categories that includes questions grouped into a plurality of tiers ranked according to urgency. Each of the plurality of tiers corresponds to one of a set of triage dispositions. At least a first relevant triage category and a second relevant triage category can be selected from the plurality of triage categories based on information about a medical condition of the person and then accessed. The person can be triaged by (a) identifying from all of the selected relevant triage categories a highest urgency tier that has at least one unasked question; (b) asking the person one of the at least one unasked question of the highest urgency tier; and (c) repeating (a) and (b) for all of the selected triage categories until the triage disposition is determined.
