Saranbut et al reported several models for predicting the risk of a decreased glomerular filtration rate (GFR) at 10 years in a mixed Asian population. This can help to identify a patient who may benefit from interventions to reduce the risk. The authors are from Mahidol University in Bangkok.
Patient selection: Asian with eGFR >= 60 mL per min per 1.73 sq meter at baseline
Outcome: eGFR < 60 mL per min per 1.73 square meter within 10 years
Parameters:
(1) age in years
(2) sex
(3) body mass index (BMI) in kg per square meter
(4) diabetes
(5) systolic blood pressure

total score =
= SUM(points for all of the parameters)
Interpretation:
• minimum score: -2
• maximum score: 12
• The higher the score the greater the risk of decreased GFR.
