Okazaki et al reported a modified APACHE II score with a reduced number of parameters. The authors are from Nippon Medical School in Chiba and Nippon Medical School in Tokyo.
Parameters:
(1) mean arterial pressure (MAP) in mm Hg
(2) serum sodium in mmol/L
(3) serum potassium in mmol/L
(4) serum creatinine in mg/dL
(5) Glasgow coma scale (GCS)
(6) age in years
points for GCS =
= 15 - (GCS)

total score =
= SUM(points for all of the parameters)
Interpretation:
• minimum score: 0
• maximum score: 34
• A score >= 10 was associated with a greater risk of all-cause mortality.
