SDASH Score of Diesing et al for Predicting Shunt Dependence After Aneurysmal Subarachnoid Hemorrhage (aSAH)

Description

Driesing et al reported the SDASH score for evaluating a patient after aneurysmal subarachnoid hemorrhage (aSAH). The authors are from Charite Universitatsmedizin Berlin and Universitatsklinikum Heidelberg in Germany.

SDASH stands for shunt dependency in aneurysmal subarachnoid hemorrhage.

Patient selection: aneurysmal subarachnoid hemorrhage

Parameters:

(1) presence of acute hydrocephalus

(2) BNI score of Wilson et al (from 1 to 5)

(3) Hunt & Hess grade from I to V

Parameter	Finding	Points
acute hydrocephalus	absent	0
	present	2
BNI score	1 or 2	0
	3 to 5	1
Hunt & Hess grade	I, II or III	0
	IV or V	1

total score =

= SUM(points for all 3 parameters)

Interpretation:

• minimum score: 0

• maximum score: 4

• The higher the score the greater the risk of shunt dependency.

Based on Figure 1:

Score	Shunt Dependency
0	2%
1	17%
2	40%
3	48%
4	75%

Performance:

• The area under the ROC curve is 0.79.
