Abstract
Background and Purpose—Immediate access to physicians experienced in acute stroke treatment may improve clinical outcomes in patients with acute stroke. Interactive telemedicine can make stroke specialists available to assist in the evaluation of patients at multiple urban or remote rural facilities. We tested whether interrater agreement for the NIH Stroke Scale (NIHSS), a critical component of acute stroke assessment, would persist if performed over a telemedicine link. Methods—One bedside and 1 remote NIHSS score were independently obtained on each of 20 patients with ischemic stroke. The bedside examination was performed by a stroke neurologist at the patient’s bedside. The remote examination was performed by a second stroke neurologist through an interactive high-speed audio-video link, assisted by a nurse at the patient’s bedside. Kappa coefficients were calculated for concordance between bedside and remote scores. Results—Remote assessments took slightly longer than bedside assessments (mean 9.70 v...
