Intensive Care After Thrombolysis (ICAT) Score of Faigle et al for a Patient with Stroke

Description

Faigle et al developed a simple score for evaluating patient who have undergone thrombolytic therapy for a stroke. The score can help to identify a patient who may require intensive care afterwards. The authors are from the Johns Hopkins University in Baltimore.


 

Patient selection: stroke patient status post thrombolysis

 

Parameters:

(1) gender

(2) race

(3) systolic blood pressure in mm Hg

(4) NIHSS (National Institutes of Health Stroke Scale) score

total score =

= SUM(points for all 4 parameters)

 

Interpretation:

• minimum score: 0

• maximum score: 8

• The higher the score the greater the need for ICU care.

• A score >= 2 indicates that the patient will probably need ICU care.

 

Performance:

• The area under the ROC curve is 0.78.

• The sensitivity was 97% and specificity 28%.
