However, with few exceptions, radiology departments in general hospitals “lack the necessary physical infrastructure, facilities, and staff training required for paediatrics.” These deficiencies can adversely affect a patient's behaviour and emotions, exacerbating fear of the healthcare system. This study sought to identify the challenges faced by radiographers in Ireland during paediatric imaging, with a focus on post-qualification training and the use of distraction techniques. A cross-sectional, qualitative online survey was conducted via Microsoft Forms, comprising 37 close-ended and eight open-ended questions on paediatric training, challenges, and distraction use. Ninety-six participants were recruited through snowball sampling from 26 hospitals and private clinics across Ireland. Only a small proportion of radiographers (n = 25, 26%) undertook post-qualification training in paediatric imaging, and many reported inadequate educational opportunities (n = 52, 60%). Patient cooperation (n = 45, 52%) and toddlers (n = 75, 90%) were identified as the most challenging aspect and age group, respectively. While distraction is commonly employed (n = 79, 91%), radiology departments often provide insufficient equipment (n = 65, 76%). The lack of equipment and training highlights the need for improvement in paediatric medical imaging services. The development of new training courses and distraction tools may enhance practice, ensuring the provision of high-quality paediatric care. Expanding radiographer training and implementing distraction tools may help paediatric patients better cope with the anxiety and stress associated with healthcare settings.</div></div>","PeriodicalId":16920,"journal":{"name":"Journal of Radiation Research and Applied Sciences","volume":"17 4","pages":"Article 101129"},"PeriodicalIF":1.7,"publicationDate":"2024-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142319808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
