Usefulness of Clinical Prediction Rules D-dimer and Arterial Blood Gas Analysis to Predict Pulmonary Embolism in Cancer Patients

摘要

ObjectivesPulmonary embolism (PE) is seven times more common in cancer patients than non-cancer patients. Since the existing clinical prediction rules (CPRs) were validated predominantly in a non-cancer population, we decided to look at the utility of arterial blood gas (ABG) analysis and D-dimer in predicting PE in cancer patients.
