The Wells score is a clinical prediction tool used to estimate the probability of pulmonary thromboembolism (PTE) in patients. It is based on a set of criteria that assess risk factors and clinical signs, helping healthcare providers make informed decisions about further diagnostic testing or treatment.

Interpretation of Scores

• Low Probability (0-1 points): PTE is unlikely.
• Moderate Probability (2-6 points): Consider further diagnostic testing.
• High Probability (>6 points): High likelihood of PTE, immediate action required.
