Trends and patterns in the use of computed tomography in children and young adults in Catalonia - results from the EPI-CT study. Pediatr Radiol. 2016 Jan;46(1):119-29.

OBJECTIVE: To assess the rate of CT scanning in Catalonia, Spain, among patients younger than 21 years old at the scan time. MATERIALS AND METHODS: This is a sub-study of a larger international cohort study (EPI-CT, the International pediatric CT scan study). Data were retrieved from the radiological information systems (RIS) of eight hospitals in Catalonia since the implementation of digital registration (between 1991 and 2010) until 2013. RESULTS: The absolute number of CT scans annually increased 4.5% between 1991 and 2013, which was less accentuated when RIS was implemented in most hospitals. Because the population attending the hospitals also increased, however, the rate of scanned patients changed little (8.3 to 9.4 per 1,000 population). The proportions of patients with more than one CT and more than three CTs showed a 1.51- and 2.7-fold increase, respectively, over the 23 years. CONCLUSION: Gradual increases in numbers of examinations and scanned patients were observed in Catalonia, potentially explained by new CT scanning indications and increases in the availability of scanners, the number of scans per patient and the size of the attended population.application/pdfengThis article is distributed under the terms of the Creative Commons Attribution 4.0 International License (http://creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.TomografiaAdolescents -- CatalunyaInfants -- Catalunyainfo:eu-repo/semantics/articlehttp://dx.doi.org/10.1007/s00247-015-3434-5info:eu-repo/semantics/openAccess
