Background

King Abdulaziz Medical City (KAMC) is a large tertiary care hospital in Riyadh, Saudi Arabia with a bed capacity of 1500. There is currently lack of sufficient reported data of reject analysis in Kingdom of Saudi Arabia. This study is the first of its kind and scale to be conducted at KAMC. The results of this study helps to improve radiological services and reduce the unnecessary radiation exposure to the patients.

Summary of Work

In our study, we have identified that the most common reason for rejection is labeling which constitute 22%. Based on American Association of Physicists in Medicine, the variation in rejection showed a factor of three between different types of hospitals. The factor of three has been demonstrated in positioning between KAMC and David H. Foos et al. (Table1). Exposure factor error in David H. Foos et al. have comparable results with our study due to the utilization of digital systems which have extended dynamic range. In contrary, Nasrollah Jabbari et al. shows a significant rejection of exposure factor due to the limited exposure latitude (Table1).

In terms of body parts, more than (70%) of the rejected radiographs were either for extremities or chest (Table2).

Conclusion

Radiographs reject analysis has been used to investigate the quality of radiographic examinations in KAMC Radiology department. Based on AAPM recommendation, rejection should be collected and analyzed on at least a quarterly basis, but preferably monthly. Also, it is recommended to have training sessions quarterly or monthly for the technologist. Results of the analysis of the rejection can be utilized to plan for training programs and continuous education and used as a base line for need assessment.
