Background And Objective:
Diagnosing pulmonary thromboembolism (PTE) is difficult. Clinical probability scales (CPS) can help. The aim is to find out which one is the best.
Patients And Methods:
A retrospective cross-sectional single-center study was conducted. It evaluated four CPS (Pulmonary Embolism Rule Out Criteria [PERC], Wells, Geneva, and YEARS criteria) validity in 200 patients who underwent computerized tomography angiography of the pulmonary arteries. Their degree of use was estimated, as well as the possible correlation between them and DD (D dimer).
Results:
The four CPS have a high sensitivity, close to 1 and without differences between them. The YEARS scale is between 2 and 4 times more specific than the others. The degree of use of the scales was estimated at 14% (95% CI: 9.19-18.81). A weak positive correlation was found between the scores on the Wells and Geneva scales and the DD.
Conclusions:
The YEARS scale is shown to be better than the others due to its potential greater number of imaging tests avoided and the degree of application of the CPS could be improved.
