Purpose: Identify patients that have an increased probability of having a pulmonary embolism based on specific patient characteristics.
Stage of CPR Development: Validated.
Rule:
| Clinical Characteristic | Score |
| Age 65 years or over | +1 |
| Previous Deep Vein Thrombosis or Pulmonary Embolism | +3 |
| Surgery or fracture within 1 month | +2 |
| Active malignant condition | +2 |
| Unilateral lower limb pain | +3 |
| Haemoptysis | +2 |
| Heart rate 75 to 94 beats per minute | +3 |
| Heart rate 95 or more beats per minute | +5 |
| Pain on deep palpation of lower limb and unilateral oedema | +4 |
