Objectives:
Many trauma patients are evaluated at community hospitals and rural emergency departments before transfer to regional trauma centers. Radiographic studies are often duplicated, leading to significant additional costs to the healthcare system. Our purpose is to identify the reasons for duplicate studies, the costs associated with this practice, and potential clinical effects to patients.
Methods:
The institutional trauma database was queried to identify patients with orthopaedic injuries transferred to our regional trauma center. Patient demographics, mechanism of injury, referring hospital, reason for transfer, payor source, injury severity score, and Glasgow Coma Score (GCS) were recorded. Duplicate imaging studies were identified and confirmed with each outlying hospital radiology department. The radiation exposure was estimated based on average reported values. The cost of duplicated studies was derived from the Medicare fee schedule.
Results:
In 1 calendar year, a total of 513 patients were accepted in transfer from 36 outlying facilities. Almost half of the patients (47.7%) had at least 1 radiographic study repeated. There was a significant association between repeated study and age (P < 0.0001), Injury Severity Score (P < 0.0001), and GCS (P < 0.0001). No association was identified for size of transferring institution, injury mechanism, or payor status. Reasons listed for duplication included inadequate data transfer, poor quality, inadequate study, and physician preference. The additional cost to the healthcare system is estimated to be $94,000.
Conclusions:
The duplication of imaging studies at regional trauma centers is a common problem that represents a significant opportunity for cost savings and reduction of patient exposure to radiation by implementing imaging protocols at outlying facilities and improving the transfer of imaging data through information technology solutions.

The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
