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)

Arguments

age_gt_65	Numeric (0 or 1). Age > 65 years. (1 = Yes, +1 point).
previous_dvt_pe	Numeric (0 or 1). Previous Deep Vein Thrombosis (DVT) or Pulmonary Embolism (PE). (1 = Yes, +3 points).
surgery_or_fracture_1mo	Numeric (0 or 1). Surgery (under general anesthesia) or lower limb fracture within the past month. (1 = Yes, +2 points).
active_malignancy	Numeric (0 or 1). Active malignant condition (solid or hematologic malignancy, currently active or considered cured < 1 year). (1 = Yes, +2 points).
unilateral_lower_limb_pain	Numeric (0 or 1). Unilateral lower limb pain. (1 = Yes, +3 points).
hemoptysis	Numeric (0 or 1). Hemoptysis. (1 = Yes, +2 points).
heart_rate	Numeric. Heart rate in beats per minute. (75-94 bpm: +3 points; >= 95 bpm: +5 points).
lower_limb_deep_vein_palpation_edema	Numeric (0 or 1). Pain on lower limb deep venous palpation and unilateral edema. (1 = Yes, +4 points).

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)
# Score = 13
