Model of Kadar et al for Blood Transfusion in a Patient with a Hip Fracture

Kadar et al reported a model for predicting blood transfusion in a patient with a hip fracture. The authors are from Tel Aviv University in Israel.

Patient selection: admitted for hip fracture

Parameters:

(1) sex

(2) age in years

(3) type of implant

(4) hemoglobin on admission

(5) INR on admission

X =

= SUM(points for all 5 parameters) + 5.1

probability of blood transfusion within 72 hours of admission =

= 1/(1+EXP((-1) * X))
