- Brief Summary
Observational prospective single-center study on the discriminatory value of the Unassisted TeleStroke Scale for differentiation between patients with lacunar stroke and those with other acute stroke syndromes.
- Detailed Description
Assessment of stroke severity and differentiation between large-artery and small-artery stroke is pivotal for adequate treatment decision taking. Patients with small vessel stroke tend have a better prognosis than those with large artery disease. Further, patients with small artery infarction (lacunar stroke) have shown to respond well to treatment with intravenous recombinant tissue plasminogen activator (IV rt-PA), but are poor candidates for endovascular recanalization. Conversely, IV rt-PA may be less effective at restoring perfusion of large artery occlusion, a stroke subtype that may benefit from intra-arterial thrombolysis or embolectomy. Similarly, patients with large intracerebral hemorrhage or cerebellar hemorrhage may require neurosurgical interventions, such as intracranial pressure monitoring, ventricular drainage, surgical evacuation, or hemicraniectomy.
The purpose of TeleCLASS is to evaluate the discriminatory value of the Unassisted TeleStroke Scale (UTSS) obtained through in-hospital telemedicine for differentiation between patients with lacunar stroke and those with other acute stroke syndromes (nonLACS).

- Primary Outcome Measures
Name Time Method Predictive validity of the UTSS for patient classification between lacunar syndromes and other stroke syndromes based on the Oxfordshire Community Stroke Project classification. within 3 days Receiver operating curves, c-statistics, optimal thresholds, likelihood ratios and accuracy measures (sensitivity, specificity, positive predictive value, negative predictive value and overall accuracy) will be calculated to evaluate the predictive ability of the UTSS for discrimination between lacunar syndrome (LACS) and other stroke syndromes (nonLACS)
- Secondary Outcome Measures
Name Time Method Predictive validity of the UTSS for vessel status, classifying patients with acute ischemic stroke between those with large-artery occlusion and those without large-artery occlusion on imaging. within 3 days Receiver operating curves, c-statistics, optimal thresholds, likelihood ratios and accuracy measures (sensitivity, specificity, positive predictive value, negative predictive value and overall accuracy) will be calculated to evaluate the predictive ability of the UTSS for discrimination between patients with large-artery occlusion and those without large-artery occlusion on imaging.
Predictive validity of the total UTSS score with cutoff value 6 for patient classification between lacunar syndromes and other stroke syndromes based on the Oxfordshire Community Stroke Project classification. within 3 days Likelihood ratios and accuracy measures (sensitivity, specificity, positive predictive value, negative predictive value and overall accuracy) will be calculated to evaluate the predictive ability of the UTSS for discrimination between lacunar syndrome (LACS) and other stroke syndromes (nonLACS)
