The ABCD2 score is a clinical prediction rule used to determine the risk for stroke in the days following a transient ischemic attack Its usefulness was questioned. The California, ABCD, and ABCD2 risk scores (ABCD system) were developed to help stratify short-term stroke risk in patients with TIA (transient ischemic. However, the ABCD2 and related scores have achieved particular prominence such that the ABCD2 score is recommended for use in UK stroke prevention.

Intracranial and extracranial occlusion also is an independent risk factor of recurrent stroke [ 4154 ]. We hand-searched all proceedings of the International Stroke Conference and the European Stroke Conference However, there is no obvious trend in either the 7- or day stroke risk or in the performance of the ABCD2 score in more recent years compared with earlier years, even allowing for the republication of some earlier data sets among later meta-analytic studies.

Absence of usefulness of ABCD score in the early risk of stroke of transient ischemic attack patients. Since the publication of this systematic review, a number of further studies evaluating the ABCD2 score have been published, with conflicting results. Clinical- and imaging-based prediction of stroke risk after transient ischemic attack: Systematic review of stroe risks of carotid endarterectomy in relation to the clinical indication for and timing of surgery.
Although these patients do not require hospitalisation, but it should be kept in mind that they may still require medical treatment or intervention. At 30 days, the risks of stroke were 2.
The predictive value of the ABCD2 scoring system needs to be clarified before widespread clinical use. ABCD sponsors treatment for those in need regardless of gender, race or creed, helping them to reach their full potential, to live life with dignity and to take their rightful abcs2 in their community.

All studies used a time-based definition xbcd2 TIA as opposed to the recently new proposed tissue-based definition. In general, the discriminatory capability of a prognostic score is measured by the area under the curve AUC of a ROC curve where sensitivity is plotted against specificity [ 2829 ].
Therefore, even in low risk patients clinically significant etiologic factors compound the stroke risk. TIA diagnosis was made by a neurologist in 14 studies, by an emergency medicine physician in six studies, initially by an emergency medicine physician and subsequently confirmed by a neurologist in two studies and by a stroke physician in another two studies; The status of the diagnosing physician was not reported in the remaining two studies.
Stead In this population of patients with TIA patients, a rapid ED-based outpatient protocol that included early carotid imaging and treatment when abcdd2, found that the rate of stroke was independent of ABCD 2 risk stratification. To reduce the impact of any between-study heterogeneity, we considered separately the 10 abcs2 that provided data on stroke risk at both 7 and 90 days.

Of these, we considered 59 reports to be potentially relevant and retrieved the full-text articles for detailed assessment. We also collected information on the following methodological aspects, which we considered more likely to introduce potential biases: The number of recurrent events at 90 days was strangely low compared with that at 7 days see Table 5.
The searches were initially run in Novemberand updated in November Johnston The largest ED-based study was a prospective cohort study of 2, subjects and found that the ABCD 2 score performed poorly in the acute setting.
At 7 days, risk of stroke were 1. The ABCD score was predictive of stroke risk 7 day. It is appropriate to hospitalise patients with a score of four or more and investigate for underlying cause strlke initiate treatment.
However, they did observe that many studies come from the same few research groups and, like us, experienced difficulty in avoiding double-counting of the same patient data appearing in multiple publications. The pooled stroke risk at 7 and 90 days for these nine studies is shown in Table 8 these studies did not provide data on stroke risk after 90 days.
Patients were categorised into 3 groups according the ABCD2 score as low risk pointsmedium risk pointsand high risk points. In a study of TIA patients who underwent brain imaging 3 or more days after the event, higher scores of California and ABCD rules which indicates higher short-term stroke risk were associated with positive DWI lesions [ 44 ].
ED doctors especially should use ABCD2 scoring since it is easier and faster compared to other diagnostic methods.
Points to keep in mind: As mentioned previously, many TIA patients have DWI strokd [ 134647 ], and these changes are associated with more definitive TIA symptoms such as unilateral weakness, speech disturbance, and vascular risk factors such as large artery atherosclerosis and atrial fibrillation [ 44 ]. Pooled stroke risks for ABCD2 dichotomised score for the sttroke studies that reported data at both 7 days and 90 days. Notably, patients with AF, significant symptomatic carotid stenosis, mechanical heart valve and a proven dissection were excluded.
Risk of stroke early after transient ischaemic attack: In transient ischaemic attack patients with an ABCD2 score of four or higher had a markedly increased short-term stroke risk, while those with a lower score were quite safe.
