Score of Finks et al for Venous Thromboembolism After Bariatric Surgery

Description

Finks et al developed a score for predicting the risk of venous thromboembolism after bariatric surgery. This can help to identify a patient who may benefit from more aggressive management. The authors are from multiple institutions in Michigan participating in the Michigan Bariatric Surgery Collaborative.

Patient selection: bariatric surgery candidate

Parameters:

(1) type of bariatric surgery

(2) history of venous thromboembolism

(3) sex

(4) duration of surgery in hours

(5) body mass index (BMI) category

(6) age category

BMI	Category
< 40	1
40 to 49.99	2
50 to 59.99	3
>= 60	4

Age	Category
< 30 years	1
30 to 39.99	2
40 to 49.99	3
50 to 59.99	4
>= 60	5

Parameter	Findiing	Points
type of surgery	duodenal switch	2.25
	open gastric bypass	1.87
	laparoscopic gastric bypass	1.38
	sleeve gastrectomy	1.25
	adjustable gastric band	0
history of thrombosis	no	0
	yes	1.42
sex	female	0
	male	0.733
duration of surgery	<= 3 hours	0
	> 3 hours	0.622
BMI		* 0.311
age		< category> * 0.223

X =

= SUM(points for all 6 parameters) - 8.90

probability of venous thromboembolism =

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