PE Calc

The PE Calc app is a calculator based on the Wells’ Criteria prediction rules. The well-validated clinical prediction rule can be applied on the spot to help predict the pretest probability of pulmonary embolism (PE).

When history and physical reveal suspicion of a PE, the PE Calc app can be used to identify patients for whom VTE (venous thromboembolism) is a diagnostic possibility. At risk patients should undergo further testing.

Description
To use PE Calc, enter a yes or no response to each of the criteria:

1. Does the patient exhibit clinical signs & symptoms of DVT?

2. Is PE the #1 diagnosis, or equally likely?

3. Is the heart rate greater than 100?

4. Has the patient been immobilized at least 3 days or undergone surgery within the past 4 weeks?

5. Was the patient objectively diagnosed with PE or DVT previously?

6. Is the patient experiencing hemoptysis?

7. Has the patient received therapeutic or palliative treatment for malignancy within the past 6 months?

PE Calc accepts yes or no answers and assigns a point value to each of the criteria, calculating the total points. PE Calc will then rate patient risk at low, moderate or high probability for PE.
