Each year, the Food and Drug Administration (FDA), the Conference of Radiation Control Program Directors (CRCPD), and state radiation control programs conduct a Nationwide Evaluation of X-ray Trends (NEXT) survey of a specific radiographic examination at randomly selected facilities across the nation. Data is collected by state inspectors using a standard protocol. The data is submitted to and evaluated by the FDA. The findings are published through the CRCPD, and are used by numerous entities in comparing entrance skin exposures (ESE) within states and between facilities.
On July 1, 1994, the x-ray section began a computerized tracking program for ESE data that was being collected throughout the state. This program allows the Division to compare Utah ESE data with the data found in the NEXT surveys. The attached graphs and charts provide information regarding the AP lumbo-sacral spine radiographic examingation collected at hospitals, private practice, and chiropractic facilities for the Utah and NEXT surveys. While the Utah data compares favorably with national data, there are opportunities to help facilities improve their examination procedures to lower patient exposures while producing quality radiographs.
