The first step is to determine your patient's pretest probability because the recommendations vary based on risk. I can tell you that many ED patients come in with a Wells score of 1-2, which places them in the "moderate pretest probability" category. There are 2 approaches you can take based on the availability of resources at your site (high-sensitivity D-dimer or U/S) and the patient's comorbidities. Are you referring your patient for a repeat outpatient ultrasound, if warranted?
