Description

Lurz et al reported a frailty score for pediatric patients with chronic liver disease. The authors are from multiple hospitals in Canada and the United States.


Patient selection: pediatric patient with chronic liver disease

 

Frailty elements measured:

(1) weakness (grip strength)

(2) slowness (walking distance)

(3) shrinkage (body constitution, triceps skinfold thickness)

(4) exhaustion

(5) diminished physical activity

• A score > 5 indicates frailty.

 

Performance:

• The area under the ROC curve was 0.83.
