Films reject analysis for conventional radiography in Iranian main hospitals.

The purpose of this study was to evaluate image quality, to determine the reject film rate in conventional radiology procedures and to determine the causes of defects on the films. Rejected films were collected in four main hospitals in Iran and five routine examinations were considered. The rejected films were analysed and assigned to five different categories. There was a significant reduction in the overall film reject rate for all examinations investigated from 17.6 to 11.4 % when a quality assurance (QA) programme was implemented. The major reasons for rejection of films were over- or under-exposure and processing problems. The study showed the importance of a QA programme in order to deliver high-quality health service to patients.
