Abstract
The severity of the initial neurological deficit is a critical determinant of outcome after acute stroke. Retrospective outcome studies are generally limited by a lack of quantitative data relating to this initial stroke severity. We evaluated the validity and reliability of measuring initial stroke severity retrospectively with the Canadian Neurological Scale (CNS). The CNS was used to prospectively score the initial neurological deficit in a series of patients with acute ischemic stroke (n = 24). An algorithm was devised for applying the CNS retrospectively on the basis of information in the patient's hospital discharge summary. Those dictating the discharge summaries were not aware of the study, and the retrospective scoring was performed without reference to other scores. The level of agreement between the prospective and retrospective scores (validity) and both intraobserver and interobserver reliability for the retrospective scores were determined. Agreement was high between retrospective and prospective scores (r = .84, R2 = .71, P < .0001), between two sets of retrospective scores obtained by one rater (r = .95, R2 = .91, P < .0001), and between retrospective scores obtained by different raters (r = .91, R2 = .82, P < ....Continue Reading
