Glasgow Coma Scale to Modified Rankin Scale Converter

Glasgow Coma Scale to Modified Rankin Scale Conversion Explanation

The Glasgow Coma Scale (GCS) assesses a patient’s level of consciousness on a scale from 3 (deep coma) to 15 (fully alert), based on three components: Eye Response (1–4), Verbal Response (1–5), and Motor Response (1–6). It is widely used in acute settings like traumatic brain injury or stroke. The Modified Rankin Scale (mRS) measures functional disability from 0 (no symptoms) to 6 (death), focusing on long-term outcomes. This converter correlates GCS scores with approximate mRS scores to estimate functional impact, though outcomes vary by individual and condition.

The converter calculates the total GCS score by summing Eye, Verbal, and Motor responses or accepting a direct GCS input (3–15, decimals allowed for partial scores). GCS is categorized as Severe (3–8), Moderate (9–12), or Mild (13–15). Based on clinical correlations, GCS scores map to mRS: GCS 15 ≈ mRS 0–1 (no/minimal disability), 13–14 ≈ mRS 1–2, 9–12 ≈ mRS 3–4, 6–8 ≈ mRS 4–5, and 3–5 ≈ mRS 5–6. Input in any editable field updates all others, with integer inputs for components and a read-only mRS output including a description (e.g., “3: Moderate disability”).
