In cliot: Clinical Indices and Outcomes Tools

Aortic Dissection Detection Risk Score (ADD-RS)

Description

Calculates the ADD-RS to stratify the pre-test probability of acute aortic dissection. The score is based on the presence of features in three categories: Predisposing Conditions, Pain Features, and Physical Exam Findings. The presence of any feature in a category awards 1 point, for a maximum score of 3.

Usage

aortic_dissection_detection_risk_score(high_risk_conditions,
high_risk_pain, high_risk_exam)

Arguments

high_risk_conditions	Numeric (0 or 1). Presence of any high-risk condition: Marfan syndrome, connective tissue disease, family history of aortic disease, known aortic valve disease, recent aortic manipulation, or known thoracic aortic aneurysm. (1 = Present).
high_risk_pain	Numeric (0 or 1). Presence of any high-risk pain feature: Abrupt onset, severe intensity, or ripping/tearing sensation. (1 = Present).
high_risk_exam	Numeric (0 or 1). Presence of any high-risk exam feature: Pulse deficit, systolic BP differential, focal neurological deficit (with pain), new aortic insufficiency murmur, or hypotension/shock. (1 = Present).

Value

A list containing:

ADD_RS_Score	The calculated score (Range 0-3).
Risk_Category	Risk classification (Low = 0, Moderate = 1, High = 2-3).
Recommendation	Guidance on workup (D-dimer vs. Imaging) based on AHA/ACC guidelines.
