Reliability and Validity of Estimating the NIH Stroke Scale Score from Medical Records

Abstract: Background and Purpose-The aim of our study was to determine whether the National Institutes of Health Stroke Scale (NIHSS) can be estimated retrospectively from medical records. The NIHSS is a quantitative measure of stroke-related neurological deficit with established reliability and validity for use in prospective clinical research. Recently, retrospective observational studies have estimated NIHSS scores from medical records for quantitative outcome analysis. The reliability and validity of estimation base… Show more

“…NIHSS is the most widely used scale of stroke severity and has been implemented both in randomized controlled acute stroke trials 15 and in observational studies. 16 Strengths of the NIHSS scale include its simplicity, the short time needed to assess it, the extensive assessment of its inter-rater reliability 17 which further increases with the use of available videotape training, 18 and the ability to extract the scale using medical records. 17 NIHSS score has already been shown to predict stroke outcome.…”

“…Scores between 0 and 5 are generally classified as mild, and scores exceeding 15 are generally classified as severe. The NIHSS predicts short-and long-term neurologic outcomes and can be reliably abstracted from the medical record [22,23,25].…”
