General practitioners trained in compression ultrasonography have excellent accuracy and agreement in diagnosing symptomatic proximal deep vein thrombosis.
In a study of more than 1,000 outpatients with clinically suspected deep vein thrombosis, diagnosis was performed by physician experts in vascular ultrasonography and GPs trained in the technique.
Expert physicians diagnosed deep vein thrombosis in 200 patients, corresponding to an overall prevalence of 18 percent. The agreement between trained GPs and experts was excellent (95 percent CI, 0.84 to 0.88).
More rapid diagnosis, directly obtained by GPs in primary care, could improve appropriate management of deep vein thrombosis and help address the growing need for professionals trained in compression ultrasonography.
