Published findings in a peer-reviewed JAMA paper

"In this data set of more than 150 000 patient interactions with an online triage tool, the urgency of patients’ intended level of care decreased in more than one-quarter of the cases and increased in approximately 1 in 20 cases, with the remaining patients remaining at the same level."
