Discharge Neurological Deficit as a Predictor of Early Stroke Recurrence: A Nationwide Registry-Based Propensity-Matched Study.

ABSTRACT:

Background

Early stroke recurrence is a significant risk for survivors of ischemic stroke. Although admission severity is commonly used in prognosis, the predictive value of residual neurological deficits at discharge remains underexplored. We aimed to determine whether discharge National Institutes of Health Stroke Scale (NIHSS) score predicts 1-year ischemic stroke recurrence, using a large multicenter registry and propensity score matching.

Methods

We analyzed 39 947 patients with first-ever ischemic stroke from the KRS (Korean Registry of Regional Cardiocerebrovascular Center for Stroke) (2014-2022). NIHSS scores were recorded at admission (baseline) and at discharge. Patients were dichotomized by discharge NIHSS score (<5 versus ≥5); supplementary cutoffs of 16 and 21 w
