Cardiac Surgery Blood Transfusion Risk and Clinical Knowledge (TRACK) Score

Description

Ranucci et al developed the TRACK (Transfusion Risk and Clinical Knowledge) score for predicting blood transfusion associated with cardiac surgery. This can help to identify a patient who is more likely to use blood and to plan accordingly. The authors are from IRCCS Policlinico S. Donato in Milan and the University of Siena in Italy.

Patient selection: cardiac surgery

Outcome: allogeneic blood transfusion given (not number of units

Parameters:

(1) age of the patient in years

(2) gender

(3) weight and gender

(4) complex surgery

(5) preoperative hematocrit

Parameter	Finding	Points
age of the patient in years	<= 67 years	0
	> 67 years	6
gender	male	0
	female	4
weight and gender	female and >= 60 kg	0
	female and < 60 kg	2
	male and >= 85 kg	0
	male and < 85 kg	2
complex surgery	no	0
	yes	7
preoperative hematocrit	>= 40 percent	0
	< 40 percent	MIN(13, 40-HCT)

total TRACK score =

= SUM(points for all 5 parameters)

Interpretation:

• minimum score: 0

• maximum score: 32

• The higher the score the greater the likelihood of blood transfusion.

X for transfusion risk in development group =

= (0.132 * (TRACK)) - 1.288

X for transfusion risk in validation group =

= (0.123 * (TRACK)) - 0.886

probability of blood transfusion =

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

Performance:

• The AUC for the total population was 0.71.
