YEARS Diagnostic Algorithm Reduces CTPA Scans by Over 20 Percent in Cancer Patients

A study published in *JAMA* indicates that the YEARS diagnostic algorithm serves as an effective tool for identifying pulmonary embolisms in cancer patients, matching the diagnostic accuracy of standard computed tomographic pulmonary angiography (CTPA) scans while reducing the necessity for the imaging procedure by more than 20 percent. This clinical approach offers a new method for managing patients with suspected blood clots in the lungs by streamlining the diagnostic process.

Researchers evaluated the algorithm’s performance by comparing its outcomes against traditional imaging protocols. The data shows that the YEARS algorithm functions as a reliable frontline assessment, allowing clinicians to rule out pulmonary embolisms without requiring immediate CTPA scans for a significant portion of the patient population. By decreasing the reliance on these invasive imaging techniques, the study suggests a shift in how medical professionals may approach diagnostic testing for cancer patients who present with symptoms of pulmonary embolism.
