Ultrasound Device Reduces the Number of Tests Required for Inpatients and Outpatients

The conditions tested under the study were biliary-duct dilation, gallstones, splenomegaly, ascites, pleural effusion, pericardial effusion, urinary stones, urinary retention, abdominal mass, and aortic aneurysm. The research included 1,962 patients, including 726 (37%) inpatients, 510 (26%) outpatients, and 726 (37%) patients recruited from physicians’ referrals.

The results showed that after some basic training, the PUD provided a simple and effective way to improve the accuracy of the clinician’s diagnosis, and reduce the number of tests needed by a patient. The PUD exam confirmed 66% of the clinical questions, in 90% of the cases. The overall frequency of further tests needed after use of the PUD was 37%. The rate of agreement between findings of the PUD and additional tests was 89%.
