| Popis: | Purpose A recent publication from our centre revealed a disturbing finding of a significant incidence of adult fingers seen on the pediatric intensive care unit (PICU) chest radiographs. This is inappropriate occupational exposure to diagnostic radiation. We hypothesized that the incidence of adult fingers on PICU chest radiographs would decline after radiation safety educational seminars were given to the medical radiation technologists and PICU staff. Methods The present study's objectives were addressed by using a pretest-posttest design. Two cross-sectional PICU chest radiograph samples, taken before and after the administration of radiation safety education for our medical radiation technologists and PICU staff, were compared by using a χ 2 test. Results There was a 61.2% and 76.9% reduction in extraneous adult fingers, directly exposed to the x-ray beam and those seen in the coned regions of the film, respectively, on PICU chest radiographs (66.7% reduction overall). This reduction was statistically significant (χ 2 = 20.613, P Conclusions Limiting unnecessary occupational radiation exposure is a critical issue in radiology. There was a statistically and clinically significant association between radiation safety education and the decreased number of adult fingers seen on PICU chest radiographs. This study provides preliminary evidence in favour of the benefit of radiation safety seminars. Abrege But Une recente publication de notre centre revele la presence d'un nombre anormalement eleve de doigts adultes sur les radiographies pulmonaires. Cela temoigne d'une radioexposition anormale des technologues en radiologie et du personnel des USPI. Nous avons fait l'hypothese que le nombre de cas diminuerait apres les seminaires sur la securite radiologique que ceux-ci ont suivis. Methodes La technique de mesure pretest post-test a ete utilisee dans le cadre de cette etude. Deux echantillons transversaux de radiographies pulmonaires prises dans une USPI avant et apres que nos technologues en radiologie et le personnel de l'USPI ont suivi la formation sur la securite radiologique ont ete compares a l'aide d'un test χ 2 . Resultats On a remarque une reduction de respectivement 61,2 % et 76,9 % de la presence de doigts adultes directement exposes aux rayons X et apparaissant dans les regions coniques des films) sur les radiographies pulmonaires prises a l'USPI, ce qui represente une baisse globale de 66,7 %. Cette reduction est significative d'un point de vue statistique (χ 2 = 20,613, P Conclusions La reduction de l'exposition professionnelle est un probleme critique en radiologie. Nous avons constate un lien statistique important entre la formation sur la securite radiologique et la baisse du nombre de doigts adultes apparaissant sur les radiographies pulmonaires prises a l'USPI. L'etude fournit des preuves preliminaires des bienfaits de la formation en securite radiographique. |
