Example
- Khorana score > 2
- Yes
- Metastatic disease
- Yes
- Vascular or lymphatic compression
- No
- Previous VTE
- No
Result: ONKOTEV score 2 — high 6-month VTE risk.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- 0
- Low 6-month VTE risk.
- 1
- Intermediate.
- >= 2
- High. One point each: Khorana > 2, metastatic disease, vascular/lymphatic compression, previous VTE. Not a thromboprophylaxis order.
What you enter
- Khorana score > 2 (+1)
- Metastatic disease (+1)
- Vascular or lymphatic compression (+1)
- Previous VTE (+1)
