What Wells Score Calculator for Pulmonary Embolism does
The Wells Score Calculator for Pulmonary Embolism helps clinicians estimate the probability of a pulmonary embolism by ticking clinical features such as signs of deep vein thrombosis, heart rate, and recent surgery. It outputs a numerical score that classifies the patient into a two-level or three-level risk category, indicating the expected proportion of confirmed PE cases in each group. The tool is designed to guide the next steps in diagnostic imaging or treatment. Omni Calculator’s version stands out for its clear, tick-box interface that walks the user through each criterion with brief explanations, and it provides both a simplified two-tier and a detailed three-tier risk classification with published outcome proportions. A prominent disclaimer reminds users that the calculator cannot replace a professional medical assessment. Additional context on the definition of pulmonary embolism and the history of the Wells criteria is linked within the page, offering educational background alongside the calculation function.

Wells Score Calculator for Pulmonary Embolism FAQ
- Can the Wells Score Calculator replace a doctor's diagnosis?
- No, the calculator provides an estimated probability based on clinical features and must always be interpreted by a qualified healthcare professional.
- What do the two-level and three-level classifications mean?
- The two-level classification splits results into 'Pulmonary embolism unlikely' (around 12% confirmed PE) and 'likely', while the three-level adds a low-risk category (around 10% confirmed PE) between unlikely and likely.
- How are the score criteria determined?
- The score assigns points for items such as signs of deep vein tachycardia, hemoptysis, recent surgery, and prior PE or DVT, based on the original Wells criteria validation.
- Does the tool account for D-dimer results or imaging?
- No, this calculator uses only clinical signs and symptoms; D-dimer or imaging findings are separate from the Wells score calculation.
