thrive_stroke_score: THRIVE Score for Stroke Outcome

In cliot: Clinical Indices and Outcomes Tools

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)

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.

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.

Examples

# Example 1: Good Outcome Likely
# NIHSS 4 (0), Age 55 (0), No comorbidities (0)
# Score = 0

# Example 2: Poor Outcome Likely
# NIHSS 22 (7), Age 82 (2), HTN and AFib (1)
# Score = 10
