Abstract:

The present study aimed to examine the efficiency of a new digital radiography system that was installed in the Royal Adelaide Hospital in September 1997, as compared to the existing conventional radiography system. A total of 55 examinations were observed over a 3-week period in January, and these consisted of 18 digital and 10 conventional chest examinations, and 27 conventional orthopaedic examinations. These were combined with 18 digital orthopaedic examinations recorded from a prior study. Total examination time was broken into several components, of which reporting time was of the most interest. The mean reporting times for digital and conventional chest examinations were 17 and 25 min, respectively, a significant (P < 0.1) 8-min difference. The orthopaedic examinations revealed mean reporting times of 8 and 26 min for digital and conventional systems, respectively; a significant (P < 0.001) 18-min difference. These results demonstrate that the digital system is a faster, more efficient system for the reporting of X-rays.
