ribscore_trauma: RibScore for Predicting Pulmonary Complications

Description

Calculates the RibScore to predict the risk of pulmonary complications (pneumonia, respiratory failure, or need for tracheostomy) in patients with rib fractures. The score is derived from six clinical variables: age, number of fractures, presence of bilateral fractures, flail chest, chronic lung disease, and pre-injury anticoagulant use.

Usage

ribscore_trauma(age, fracture_count, bilateral_fractures, flail_chest,
                chronic_lung_disease, anticoagulant_use)

Value

A list containing:

RibScore

The calculated total score (Range 0-12).

Pulmonary_Complication_Risk

Estimated percentage risk of pneumonia, respiratory failure, or tracheostomy.

Arguments

age

Numeric. Patient age in years. <45: 0 pts. 45-64: 1 pt. >=65: 2 pts.

fracture_count

Numeric. Total number of rib fractures. <3: 0 pts. 3-5: 1 pt. >=6: 2 pts.

bilateral_fractures

Numeric (0 or 1). Presence of bilateral rib fractures. (1 = Yes, +2 pts).

flail_chest

Numeric (0 or 1). Presence of flail chest (segmental fractures of >=3 adjacent ribs). (1 = Yes, +2 pts).

chronic_lung_disease

Numeric (0 or 1). History of chronic lung disease (e.g., COPD, asthma). (1 = Yes, +2 pts).

anticoagulant_use

Numeric (0 or 1). Pre-injury use of anticoagulants (e.g., warfarin, DOACs, antiplatelets). (1 = Yes, +2 pts).

Examples

# Example 1: High Risk
# 70yo (+2), 6 fractures (+2), Bilateral (+2), Flail (+2)
# Score = 8

# Example 2: Low Risk
# 30yo (0), 2 fractures (0), No other factors
# Score = 0
