Simplified COMPASS-CAT scoring system for the prediction of VTE in ambulatory patients with common cancers on anti-cancer therapy (2017)61

Parameter	Score*
Cancer-related risk factors
Anti-hormonal therapy†	6
Time since cancer diagnosis ≤6 months	4
Central venous catheter use	3
Advanced stage of cancer	2
Predisposing risk factors
CV risk factors (at least 2 of: personal history of PAD, ischaemic stroke, CAD, hypertension, hyperlipidaemia, diabetes or obesity)	5
Recent hospitalisation for acute medical illness	5
Personal history of VTE	1
Biomarkers
Platelet count ≥350×109/L	2

*Low/intermediate risk: 0–6; high risk: ≥7.

†For women with hormone receptor-positive breast cancer or on anthracycline treatment.

CAD, coronary artery disease; CAT, cancer-associated thrombosis; CV, cardiovascular; PAD, peripheral artery disease; VTE, venous thromboembolism.
