Admission Hyperglycaemia as a Predictor of Stroke Severity and Mortality: Evidence from a Prospective Emergency Department Cohort

Main Article Content
Abstract
Background: Admission hyperglycaemia is commonly observed in acute stroke and has been linked to poorer neurological outcomes. Its role as a prognostic marker in emergency settings warrants evaluation.
Objective: To assess the association between admission random blood sugar (RBS) levels and stroke severity, and to determine its relationship with in-hospital outcomes.
Methods: This prospective observational study included 115 adult patients with radiologically confirmed stroke presenting to a tertiary care emergency department. Admission RBS levels were recorded, and stroke severity was categorized using the National Institutes of Health Stroke Scale (NIHSS). Statistical analysis was performed with p < 0.05 considered significant.
Results: Mean admission RBS levels increased significantly with stroke severity, rising from 175.6 mg/dL in minor stroke to 216.5 mg/dL in severe stroke (p < 0.01). Overall in-hospital mortality was 7%.
Conclusion: Admission hyperglycaemia correlates positively with stroke severity and may serve as a simple, rapid prognostic marker in acute stroke care.
