Hilder 2017 PRESET-Score
Hilder 2017 PRESET-Score: five Table 4 items (MAP mm Hg, lactate mmol/L, arterial pH, platelets k/uL, hospital days pre-ECMO) summed 0-15. Returns class I (0-5, 26% ICU mortality), II (6-9, 68%), or III (10-15, 93%) from the derivation cohort. Deterministic published arithmetic with citation; not a cannulation order; magent does not assay labs. Not RESP or SAVE.
