Description

Chang et al reported a model for 5-year mortality in an older adult with diabetes. The authors are from multiple institutions in Taiwan.


Patient selection: diabetic >= 65 years of age

 

Parameters:

(1) age in years

(2) sex

(3) smoking status

(4) body mass index (BMI) in kg per sq meter

(5) fasting blood glucose in mg/dL

(6) systolic blood pressure in mm Hg

(7) diastolic blood pressure in mm Hg

(9) serum total cholesterol in mg/dL

(10) hemoglobin in g/dL

(11) serum albumin in g/dL

(12) eGFR in mL per min per 1.73 square meter

(13) WBC count per microliter

(14) serum GPT in U/L

(15) uric acid in mg/dL

total score =

= SUM(points for all of the parameters)

 

Interpretation:

• minimum score: 0

• maximum score: 30

 

value of X =

= (0.07 * (67 + (5 * (score)))) - 6.2926

 

risk of 5-year mortality =

= 1 - (0.8791^(EXP(X)))

 

Performance:

• The C-index for the developmental cohort was 0.74 and for the external validation cohort was 0.69.
