This calculator helps medical professionals assess the probability of Deep Vein Thrombosis (DVT) and Pulmonary Embolism (PE) using Wells' Criteria. It is intended for use by healthcare providers to assist in decision-making and should not be used as a sole diagnostic tool.
The Wells' Criteria are based on the following authoritative source: Wells PS, et al. "Use of a clinical model for safe management of patients with suspected pulmonary embolism." Ann Intern Med. 1998;129(12):997-1005. All calculations are strictly based on the formulas and data provided by this source.
The Wells' Criteria use a scoring system to evaluate the likelihood of DVT and PE. The formula is:Score = Clinical signs + Heart rate + Immobilization + ...
Consider a patient with the following inputs: Clinical signs present (1), Heart rate above 100 bpm (1), Recent immobilization (1). The Wells' score would be calculated as 3, indicating a high probability of DVT/PE.
It is a clinical tool used to assess the probability of DVT and PE in patients.
It is widely used and validated in clinical settings, but should be used in conjunction with other diagnostic methods.
It is most applicable for patients with symptoms suggestive of DVT or PE. Always consult with a healthcare professional.
