Injury Severity Score (Baker 1974): ISS is the sum of squares of the three highest caller-assigned AIS body-region grades (head, face, chest, abdomen, extremity, external; each 0-6). Any AIS 6 (unsurvivable) is ISS 75. Deterministic published arithmetic with citation; not a triage order and not NISS (which squares the three worst injuries regardless of region).

Than 2014 EDACS from age bands, male sex, known CAD or three risk factors (age 18-50 only), diaphoresis, radiation, inspiration (−4), and palpation (−6). Returns the point total (may be negative) and whether the score is <16. The paper ADP also requires ECG and 0/2h troponin, which magent does not take. Not a diagnosis or discharge order.
