geneva_score_revised: Geneva Score (Revised) for Pulmonary Embolism

Description

Calculates the Revised Geneva Score to estimate the probability of pulmonary embolism (PE) in patients with suspected PE. This score stratifies patients into low, intermediate, or high clinical pretest probability categories based on clinical variables, aiding in the decision-making process for further diagnostic testing.

Usage

geneva_score_revised(age_gt_65, previous_dvt_pe, surgery_or_fracture_1mo,
                     active_malignancy, unilateral_lower_limb_pain, hemoptysis,
                     heart_rate, lower_limb_deep_vein_palpation_edema)

Value

A list containing:

Geneva_Score

The calculated risk score (Range 0-22).

Risk_Probability

Classification (Low 0-3, Intermediate 4-10, High >=11).

PE_Probability

Estimated probability of PE based on risk category.

Recommendation

Suggested diagnostic strategy.

Examples

# Example 1: Low Probability
# 40yo, HR 70, No other risk factors
# Score = 0

# Example 2: High Probability
# 70yo (+1), HR 100 (+5), Unilateral Pain (+3), Pain on Palpation (+4)
