Bone mineral density examination analysis errors produced are from operations and equipments. The purpose of this study is to examine the effect of quality control circle (QCC) technique on the accuracy analysis of BMD. Before QCC technique stated to use, there were 786 patients in BMD examination from March to April in 2011. Analysis errors occurred in 43 patients. According to QCC technique, data analysis error (2.3%), unspecified error (1.0%), and trend images error (0.8%). Three strategies were proposed after team discussion, double check of analysis data by the second Radiographer before uploading, updating of operating instruction, and continuing medical education and license examination. Three of previously mentioned strategies were used in subsequent improving and improved stages. In BMD examination were gathered at improved stage from July to August in 2011 for 630 patients. Analysis errors occurred in 21 patients. In BMD examination were gathered at improved stage from September to October in 2011 for 778 patients. Analysis errors occurred in 17 patients. They were, according to QCC technique, data analysis error (1.4% to 1.3%), unspecified error (0.6% to 0.4%), and trend images error (0.5% to 0.1%). Quality control circle technique was a useful tool to discover errors and improve the accuracy. This study showed QCC technique can actually decrease analysis errors. Moreover, Radiographer’s technique and knowledge are crucial to the performance of BMD examination. Continuing medical education and licensure examination can be used as references for Radiographer’s evaluation in the future.
