Abstract
AbstractA study was undertaken to identify the causes of unnecessary repeated medical imaging examinations. The repeat analysis study investigated repeated medical imaging examinations at two medium sized hospitals in Sydney, Australia. The analytical part of the study was conducted jointly by a radiologist and a radiographer. Overall there were 9.3% and 7.2% of total films repeated respectively at the two hospital sites. Unnecessary repeats were found to have been caused by numerous factors including: poor technical judgement, the adoption of unconventional techniques, non availability of radiologist for advice, patient movement or motion, equipment mishandling, disorganised practice and poor supervision of students. At both of the sites, senior radiographers were associated with 70.2% and 84.5% respectively of dark and light film errors, and 59.7% and 85.5% respectively of the repeated cases had students' involvement. On the other hand, junior radiographers were involved with 70.3% and 86.1 % respectively of positioning errors.It was recommended that major changes be introduced to radiographer practice including, quality control, radiological techniques, training, supervision and continuing professional development. It was also recommended that the radiologist takes a more active role in future guidance and training of radiographers.
