FACTORS OF FAILURE TO REPEAT X-RAY PHOTOS ON COMPUTED RADIOGRAPHY IN RADIOLOGY UNIT dr. REKSODIWIRYO HOSPITAL PADANG

Abstract

The repetition of X-rays in computed radiography is caused by incompetent human resources. Based on observations from January 2020 to June 2020 there were 123 repetitions with a repetition percentage of 4.04%. The repetition of photos received by patients related to exposure to low doses is known as the stochastic effect, no matter how small the dose received will have an effect. Therefore, it is necessary to conduct research to determine the number of repetitions and the factors that cause repetition.
The type of research used is descriptive quantitative, carried out at the Radiology installation of Rs.dr.Reksodiwiryo Padang in June 2021. The population is 4,581 examinations with a sample of 143 photos repeated. The data is grouped based on the repetition factor and calculations are carried out and then processed using a formula that will be compared with the tolerance limit that has been set.
The results of the study stated that the repetition of X-rays in January was 5.22%, February as many as 4.02%, March 3.41%, April 2.16%, May 1.42% and June 0.49%. then the average percentage of repetition for 6 months is 3.12%, while based on Permenkes No.129 of 2008 the repetition of X-rays should not exceed 2%. The factors causing repetition are patient movement factor 3.22%, patient position factor 49.03%, exposure factor 9.03%, equipment factor 3.87%, and artefact factor 34.83%.
