Estimates for cumulative changes in field triage sensitivity, specificity, under- and overtriage based on modification to the physiologic triage criteria for older adults using a validation sample (n = 17,804). The receiver operating characteristic values for each triage strategy are as follows: 0.77 (current triage criteria); 0.76 (adding GCS ≤ 14); 0.76 (adding assisted ventilation or respiratory rate < 10 or > 24 breaths/minute); 0.73 (adding SBP < 110 or > 200 mmHg); and 0.73 (adding shock index > 1.0). The respiratory criterion includes the need for assisted ventilation (bag–valve–mask ventilation or intubation) and respiratory rate < 10 or > 24 breaths/minute.
