“…There are two Thromboembolic risk assessments in use for the clinical praxis: - The Landolfi risk assessment scale, 11 which considers the following parameters as risk factors (maximum score 13): age at diagnosis (<40; 40–55; 56–65; >65 years; score 0–3.5), hypertension (score 0.5), dyslipidemia (score 0.5), platelet count >1000 × 10 9 /L (score 1.0), leukocyte count 12 × 10 9 /L (score 1.0), smoking (score 1.5), diabetes mellitus (score 1.5) and history of thrombotic events in the past (score 3.5). Patients are categorised into four TE risk groups based on their Landolfi scores (low, score < 1; moderate, score 1–3; high, score 3.1–5.5; and very high, score > 5.5) 11,12
- The Tefferi risk scale, which considers: age at diagnosis >60 years and past history of thrombosis.
