Minami-Takano et al reported the TCBI as a nutritional index for critical care patients. The authors are from multiple institutions in Japan.
Patient selection: adult in critical care
Parameters:
(1) serum total triglycerides in mg/dL
(2) serum total cholesterol in mg/dL
(3) body weight in kilograms
TCBI =
= (triglycerides) * (cholesterol) * (body weight) / 1000
Interpretation:
• Mortality was greatest in the lowest tertile and lowest in the highest tertile.
