Score of Pannucci et al for Predicting the Risk of Venous Thromboembolism After Outpatient Surgery

Description

Pannucci et al developed a score for predicting the risk of venous thromboembolism after outpatient surgery. This can help to identify a patient who may benefit from more aggressive management. The authors are from the University of Michigan with data from the ACS-NSQIP database.

Patient selection: outpatient surgery

Outcome: 30-day risk for venous thromboembolism

Parameters:

(1) arthroscopic surgery

(2) current pregnancy

(3) active cancer

(4) non-great saphenous vein surgery

(5) saphenofemoral junction venous surgery

(6) age

(7) body mass index (BMI)

(8) duration of surgery

Parameter	Finding	Points
arthroscopic surgery	no	0
	yes	6
current pregnancy	no	0
	yes	8
active cancer	no	0
	yes	5
non-great saphenous vein surgery	no	0
	yes	11
saphenofemoral junction venous surgery	no	0
	yes	10
age in years	< 40 years	0
	40 to 59 years	2
	>= 60 years	3
BMI	< 40 kg per sq m	0
	>= 40 kg per square m	2
duration of surgery	< 120 minutes	0
	>= 120 minutes	2

total score =

= SUM(points for all 8 parameter)

Interpretation:

• minimum score: 0

• maximum score: 47 (unlikely to occur)

• The higher the score the greater the risk of venous thromboembolism.

Score	Risk	30-Day VTE
0 to 2	low	0.1%
3 to 5	moderate	01 to 0.3%
6 to 10	high	0.3 to 0.5%
>= 11	highest risk	1.2%

Performance:

• The area under the ROC curve was 0.76.
