altitude_adjusted_perc_guideline v.1
A set of eight criteria to rule out pulmonary embolism (PE) in patients with low risk for PE and who live at high altitude (>4000 ft).
To rule out PE in patients with low risk for PE and who live at high altitude (>4000 ft) and to prevent unnecessary diagnostic testing. Patients with low risk for PE and a negative altitude-adjusted PERC test do not need a D-dimer assay, which is sometimes overused with this patient population.
Use in patients with low risk for PE and who live at high altitude (>4000 ft). If any of the criteria are present, PE cannot be ruled out.
Not to be used as a risk-stratification tool. Not to be used in patients who live at low altitudes.
