The Effect of Education on Repetition Rate Reduction of Radiographic Images by Students at Ahvaz Educational Hospitals

Reject and repeat radiographs causes numerous difficulties within imaging departments; in addition، relationship between education level and performance is well established، and patients and staff exposure increases due to radiographs repetition، and it will also increase the costs. Hence، the aim of this study was to evaluate the effect of education on repetition rate of radiographs images were taken by radiography students at teaching hospitals of city of Ahvaz. The participants of the study contained 70 radiography students، then the sample size was reduced to 59 students; moreover، the performance of the students was evaluated by a researcher- made check list which contained information related to the number of radiographs performed and number of radiographs repeated and rejected. Consequently، the information obtained was analyzed using SPSS version 20. Out of2496 radiographs performed before intervention in general، 284 (11/3%) were repeated; Out of those، 1026 radiographs were taken by students before interventions; out of those، 1999 (19/3%) were repeated. After interventions، 1470 of them were taken by students; only 85 ones (5. 7%) were repeated. In sum، improper positioning (9%) and incorrect exposure factors (7/3%) were the main causes of rejection and repeat radiographs. Respectively، education and alterations in the method of presentation were considered as effective factors in reducing the number of repeated radiographs. Therefore، focusing of continuing practical education، preparing exposure factor tables، and using educational Phantoms would be effective in reducing repeated radiographs.
