thrive_stroke_score: THRIVE Score for Stroke Outcome

Description

Calculates the Totaled Health Risks in Vascular Events (THRIVE) score to predict clinical outcomes (functional independence and mortality) at 90 days in patients with acute ischemic stroke. The score integrates stroke severity (NIHSS), age, and chronic medical conditions (hypertension, diabetes, atrial fibrillation).

Usage

thrive_stroke_score(nihss_score, age, history_hypertension, history_diabetes,
                    history_atrial_fibrillation)

Value

A list containing:

THRIVE_Score

The calculated total score (Range 0-10).

Good_Outcome_Probability_90d

Estimated probability of a good neurological outcome (mRS 0-2).

Mortality_Risk_90d

Estimated risk of death within 90 days.

Arguments

nihss_score

Numeric. National Institutes of Health Stroke Scale score (0-42). 0-5: 0 pts. 6-10: 2 pts. 11-20: 4 pts. >20: 7 pts.

age

Numeric. Patient age in years. 18-59: 0 pts. 60-79: 1 pt. >=80: 2 pts.

history_hypertension

Numeric (0 or 1). History of hypertension. (1 = Yes).

history_diabetes

Numeric (0 or 1). History of diabetes mellitus. (1 = Yes).

history_atrial_fibrillation

Numeric (0 or 1). History of atrial fibrillation. (1 = Yes). Note: Presence of ANY chronic disease (HTN, DM, or AF) adds 1 point total.
