General description
The pulmonary embolism rule-out criteria (PERC) helps assess people in whom pulmonary embolism is suspected, but unlikely. Unlike the Wells score and Geneva score the PERC rule is designed to rule out risk of PE in people when the physician has already stratified them into a low-risk category.
People in this low risk category without any of criteria may undergo no further diagnostic testing for PE.The rationale behind this decision is that further testing (specifically CT angiogram of the chest) may cause more harm (from radiation exposure and contrast dye) than the risk of PE. The PERC rule has a sensitivity of 97.4 % and specificity of 21.9 % with a false negative rate of 1.0 %.
