Prognostic Score of Rosa-Salazar et al for an Outpatient with Acute Deep Vein Thrombosis (DVT) in the Upper Extremity

Description

Rosa-Salazar et al reported a prognostic score for outpatients with acute deep vein thrombosis in the upper extremity. This can help to identify a patient who may benefit from more aggressive management. The authors are RIETE (Registro Informatizado de la Enfermeded TromboEmbolica) investigators from multiple hospitals in Spain.

Patient selection: outpatient with acute DVT in an upper extremity

Outcome: pulmonary embolism, major bleeding or death within the first week

The score is the same as reported by Trujillo-Santos et al for DVT of the lower extremity but with different outcome risks.

Parameters:

(1) chronic heart failure

(2) creatinine clearance in mL per minute

(3) history of recent major bleeding

(4) platelet count

(5) recent immobility for 4 or more days

(6) cancer

Parameter	Finding	Points
chronic heart failure	no	0
	yes	1
creatinine clearance	> 60 mL/min	0
	30 to 60 mL/min	1
	< 30 mL/min	3
recent major bleeding	no	0
	yes	1
platelet count	normal	0
	abnormal (less than 100,000 or greater than 450,000 per µL(	1
recent immobility	no	0
	yes	1
cancer	no	0
	without metastases	1
	with metastases	2

total score =

= SUM(points for all 6 parameters)

Interpretation:

• minimum score: 0

• maximum score: 9

• A score <= 1 was considered low risk for the outcome (less than 0.4%).

• A score >= 4 was associated with 4.9% risk of an adverse outcome.
