|
Purpose: The aim of this study was to determine the effect of external quality assurance (QA) evaluation for chest radiography in the medical institution for pneumoconiosis (MIP).
Materials and Methods : The chest radiography of the MIPs were evaluated for a radiological technique (RT), image quality (IQ), and reading environment (RE), during a 3-year follow up according to the Korean guidelines. Same methods were implemented each year to ensure that the results are reliable. RT, IQ, and RE were compared between examination and medical care (EMP), and only medical care (MCP) for pneumoconiosis, film-screen (FSR) and digital (DR) radiography. Uneducated and educated for QA during a 3-year follow up referencing with 2008 were realized.
Results: RT and IQ of the MIPs showed a significantly higher score in 2009 and 2010 compared with 2008 (p ＜ 0.01). However, RE was not significantly improved. The score of RT, IQ, and RE of the EMPs were higher than those of MCPs every year, and FSR showed a lower score in all evaluations, although, more improvement was seen than the DR.
Conclusion: The chest radiography of the MIPs showed a significant effect as a result of a repeated external QA evaluation. However, the MIPs need to transfer from FSR to DR, and maintain a continuous QA evaluation for the MCPs.
