3-Point Transfusion Risk Score of Lemke et al for Hepatectomy

Description

Lemke et al reported a simple 3-point transfusion risk score for patients undergoing hepatectomy. This can help to determine the likelihood of perioperative transfusion. The authors are from the University of Toronto, University of Western Ontario, University of Ottawa and University of Calgary in Canada.

Patient selection: hepatectomy

Parameters:

(1) hemoglobin in g/dL

(2) diagnosis

(3) number of segments resected

Parameters	Findings	Points
hemoglobin	> 12.5 g/dL	0
	<= 12.5 g/dL	1
diagnosis	primary liver cancer	1
	other	0
number of segments resected	1 to 3	0
	>= 4	1

total score =

= SUM(points for all 3 parameters)

Interpretation:

• minimum score: 0

• maximum score: 3

• The greater the score the greater the percent transfused.

Total Score	Risk	Percent Transfused
0	low	14%
1	moderate	27%
2	high	48%
3	very high	62%

Performance:

• The area under the ROC curve is 0.66.
