Predictors of Fazal et al for Perioperative Blood Transfusion in an Elderly Patient with an Extracapsular Hip Fracture Treated with a Cephalo-Medullary Nail
Fazal et al identified factors predictive of perioperative blood transfusion in an elderly patient with cephalo-medullary nailing of an extracapsular hip fracture. The authors are from Royal Free NHS Foundation Trust in Enfield, England.
Patient selection: elderly patient with extracapsular hip fracture treated with a cephalo-medullary nail. The age range was 62 to 101 years.
Parameters:
(1) age in years
(2) ASA grade
(3) preoperative hemoglobin
(4) length of the nail used

where:
• According to DePuy Synthes the short proximal femoral nail has a length of 17-20 cm vs 34-44 cm for the long.

= SUM(points for all 4 parameters)
Interpretation:
• minimum score: 0
• maximum score: 4
• The risk of perioperative blood transfusion increases with the number of predictors present.
