Abstract
This is a protocol for a Cochrane Review (diagnostic). The objectives are as follows: The primary aim of this review will be to assess the diagnostic accuracy of the HINTS examination for identifying a central etiology for AVS. SECONDARY OBJECTIVES: Secondary objectives include assessing the diagnostic accuracy of HINTS amongst the following subgroups: specific providers (e.g. physicians, non‐physicians); time from symptom onset to presentation (e.g. less than 24 hours, greater than 24 hours); reference standard (e.g. advanced imaging, discharge diagnosis); underlying etiology (e.g. ischemic stroke, alternative etiologies [hemorrhagic stroke, intracranial mass]); study setting (e.g. outpatient [outpatient clinic, urgent care clinic, ED], hospitalized patients); individual diagnostic accuracy of each subcomponent of the examination (e.g. head impulse, direction‐changing nystagmus, test of skew).
