geneva_vte_prophylaxis_score: Geneva Risk Score for VTE Prophylaxis

Description

Calculates the Geneva Risk Score for Venous Thromboembolism (VTE) Prophylaxis in hospitalized medical patients. This score stratifies patients into low or high risk to guide the decision for pharmacologic thromboprophylaxis. Note: This is distinct from the "Geneva Score" used for diagnosing PE.

Usage

geneva_vte_prophylaxis_score(heart_failure, respiratory_failure, recent_stroke,
                             recent_mi, acute_infection, rheumatic_disease,
                             active_malignancy, myeloproliferative_syndrome,
                             nephrotic_syndrome, prior_vte, hypercoagulable_state,
                             immobilization, recent_travel, age_gt_60,
                             obesity_bmi_gt_30, chronic_venous_insufficiency,
                             pregnancy, hormonal_therapy, dehydration)
