RIETE Score for Risk of Hemorrhage in Pulmonary Embolism Treatment

Description

Calculates the RIETE Score to predict the risk of major hemorrhage within the first 3 months of anticoagulant treatment for Venous Thromboembolism (VTE). The score helps stratify patients into Low, Intermediate, and High risk categories based on six clinical variables.

Usage

riete_hemorrhage_risk(age_gt_75, recent_bleeding, cancer, creatinine_gt_1_2,
                      hemoglobin_lt_13_or_12, pe_diagnosis)

Arguments

age_gt_75	Numeric (0 or 1). Patient age > 75 years. (1 = Yes, +1 point).
recent_bleeding	Numeric (0 or 1). Recent major bleeding (within 30 days prior to VTE diagnosis). (1 = Yes, +2 points).
cancer	Numeric (0 or 1). Active cancer. (1 = Yes, +1 point).
creatinine_gt_1_2	Numeric (0 or 1). Abnormal creatinine levels (> 1.2 mg/dL). (1 = Yes, +1.5 points).
hemoglobin_lt_13_or_12	Numeric (0 or 1). Anemia (Hemoglobin < 13 g/dL for men, < 12 g/dL for women). (1 = Yes, +1.5 points).
pe_diagnosis	Numeric (0 or 1). Clinically overt Pulmonary Embolism (PE). (1 = Yes, +1 point).

Value

A list containing:

RIETE_Score	The calculated risk score (Range 0-8).
Risk_Category	Classification (Low: 0, Intermediate: 1-4, High: >4).
Major_Bleeding_Risk_3_Months	Estimated risk of major bleeding.
Fatal_Bleeding_Risk_3_Months	Estimated risk of fatal bleeding.

Examples

# Example 1: High Risk
# Recent Bleed (+2), Anemia (+1.5), Creatinine >1.2 (+1.5)
# Score = 5
riete_hemorrhage_risk(0, 1, 0, 1, 1, 0)

# Example 2: Low Risk
# 60yo, No risk factors
# Score = 0
riete_hemorrhage_risk(0, 0, 0, 0, 0, 0)
