EFFECT OF THE TOOL ‘BEFAST’ ON STROKE IDENTIFICATION: A SCOPING REVIEW
Abstract
Background and Aims
FAST(Facial weakness,Arm droop,Slurry Speech and Time) which is used for identifying acute strokes mostly recognize signs which are related to anterior circulation stroke.Several medical institutions are now applying BEFAST with two components added to FAST(B-Balance disturbances /E-Eye issues) for identifying common posterior circulation stroke signs also.We aim to review and synthesize relevant knowledge on the effect of adding BE with FAST for stroke identification.
Methods
The review followed scoping methodological framework outlined by Arskey and O’Malley(2005).An extensive literature search with electronic databases like Embase,PubMed,Medline,CINAHL, APA PsycINFO,Google scholar and grey literature was undertaken.Study selection was conducted according to inclusion criteria with the help of PRISMA flowchart.Study design wasn't restricted for conducting an extensive search and date range from 2015 onwards was considered for reviewing recent research in the field.
Results
Out of 56 articles,18 articles were included in the review upon meeting the criteria.BEFAST was found to be effective in many of the included papers,even though there were few studies with no significant difference in adding'BE’to the current existing FAST.Additionally, the review pointed out BEFAST to be taking the role of a screening tool among the clinicians more than a public awareness tool.
Conclusions
The BEFAST was found to be effective as a screening tool for identification, particularly those belonging to posterior circulation.Therefore,revision of the existing tool to BE FAST may be recommended while attempting to avoid missed strokes which could manifest with posterior circulation. However,further research over larger population and variety settings are required to confirm its effect as a public awareness tool.
