Wells Criteria for Probability of Pulmonary Embolism (PE) Mnemonic

This is a mnemonic I created for the seven criteria involved with calculating the Wells Score for pulmonary embolism (PE). The Wells Score correlates with the probability that a given patient has a pulmonary embolism. The mnemonic is: Don’t die, tell the team to calculate criteria! The first letters in the saying correspond to a criteria for diagnosis. If the first letters are the same, they also have the same numerical point value for calculating the total sore.

Don’t (DVT symptoms) 3 points 
Die (Diagnosis most likely PE) 3 points 
Tell (Tachycardia) 1.5 points 
The Team (Three days [at least] of immobilization, or surgery in the past Thirty days) 1.5 points 
To (Thromboembolism in the past [DVT or PE]) 1.5 points 
Calculate (Coughing up blood [hemoptysis]) 1 point  
Criteria (Cancer) 1 point

This is what the scores mean:
> 6 High probability of PE
2-6 Moderate probability of PE
< 2 Low probability of PE

The modified Wells Criteria is a bit simpler:
> 4 PE is likely
≤ 4 PE is unlikely
