stumbl_battle_score: STUMBL (Battle) Score for Blunt Chest Wall Trauma

Description

Calculates the STUMBL (STUdy of the Management of BLunt chest wall trauma) Score, also known as the Battle Score. This clinical decision rule predicts the risk of complications (e.g., pneumonia, pleural effusion, respiratory failure) in patients with blunt chest wall trauma to guide disposition (discharge vs. admission).

Usage

stumbl_battle_score(age, num_rib_fractures, chronic_lung_disease,
                    anticoagulant_use, spo2_percent)

Value

A list containing:

STUMBL_Score

The calculated total score (Range 0-24).

Risk_Category

Risk stratification (Low <= 10, High >= 11).

Management_Guidance

Recommendations for discharge or admission based on the score.

Arguments

age

Numeric. Patient age in years. (>= 65 years adds 5 points).

num_rib_fractures

Numeric. Number of rib fractures identified on imaging. (>= 3 adds 4 points).

chronic_lung_disease

Numeric (0 or 1). History of chronic lung disease (e.g., COPD, asthma). (1 = Yes, +5 points).

anticoagulant_use

Numeric (0 or 1). Pre-injury use of anticoagulants or antiplatelet medication. (1 = Yes, +4 points).

spo2_percent

Numeric. Oxygen saturation percentage on room air. (< 90% adds 6 points).
