Hayashida et al reported the J-ERATO score for evaluating a patient with heat-related illness. This can help to identify a patient who may require more aggressive management. The authors are from multiple institutions in Japan and Masschusetts General Hospital.
J-ERATO is an acronym for Japanese Early Risk Assessment Tool for Detecting Clinical Outcomes in Patients with Heat heat-related illness
Patient selection: adult with heat-related illness
Parameters:
(1) respiratory rate in breaths per minute
(2) Glasgow coma scale
(3) systolic blood pressure in mm Hg
(4) prehospital heart rate in beats per minute
(5) body temperature in °C
(6) age in years
