Analys av filmkassation: Ett SSI-projekt
1996 (Swedish)Report (Other academic)
Reject analysis in a radiology department can play an important role in the quality assurance process. Reject analysis was performed in the Department of Radiology, University Hospital in Linköping, Sweden, during 22 weeks 1992 and 5 weeks 1994. Between the two occasions, an education and training program was carried through. The rejected films were classified acording to 6 criteria. The reject frequency was 9.9% before and 8.5% after. Faulty exposure and faulty positioning of the patient contributing with 53 % of all rejected films.
It was shown that reject analysis can easily be carried through. Compared to reports from the literature, the level found here was neither high nor low. The decrease in reject frequency after the training program was low and probably not significant. Reducing the rejections results in reduced patient doses and lower costs for the films. However, too low frequencies may be an indication of accepting bad image quality and reduced diagnostic accuracy. In the future when digital equipment is more frequently introduced the rejection of films will decrease, but not necessarily the retakes. Here, measurements of mean absorbed doses to the patients may provide a better toal for quality assurance of the radiology department.
