Introduction: Imaging tests are essential for diagnosis in the emergency context and convey clinical information that is essential to assess the appropriateness of the tests and improve their interpretation. Therefore, we aimed to analyze the imaging tests requested by the Emergency Department in a district hospital.Material and Methods: We retrospectively analyzed computed tomography and ultrasound scans requested by the Emergency Department at the Centro Hospitalar Universitário do Algarve and considered the following variables: requested test, clinical information provided (complete/incomplete), appropriateness of the test (appropriate/inappropriate), outcome (presence/absence of relevant findings) and findings related to the clinical information (yes/no). Pearson’s chi-squared and odds ratio association tests were used to evaluate the statistical association between the variables.Results: Out of 1427 requests, only 219 (15.3%) were considered to have complete clinical information. Nonetheless, 1075 (75.3%) requests were considered appropriate. Relevant findings were present in about one-third (n = 453; 31.7%) and most of these findings were related to the clinical context (n = 410; 90.5%). There was a significant association between test appropriateness and the presence of relevant findings in the test (p < 0.001). The odds ratio of having a relevant finding was 5.0 times higher in the tests considered appropriate when compared with those classified as inappropriate (CI = 3.4 - 7.3; p < 0.001).Discussion: The fact that appropriate tests potentiate the probability of having a relevant finding emphasizes the importance of defining guidelines so that only the adequate tests are performed.Conclusion: Creating guidelines should improve the appropriateness of imaging tests requested in the Emergency Department, yielding their result, with the consequent rationalization of the available resources.
Este artigo refere-se à história de uma grande coleção, formada aproximadamente por 4.300 obras em 5.700 volumes.1 Uma compilação que contém álbuns de retratos em estampas, opúsculos, mapas e obras avulsas, agrupados por zelo e diligência de Diogo Barbosa Machado (1682-1772), abade de Santo Adrião de Sever. Como se sabe, este conjunto documental foi doado à Real Biblioteca entre 1770 e 1773, após o grande terremoto de 1755 que acometeu Lisboa, praticamente destruindo aquele acervo original. Em 1810, a Livraria Barbosa Machado viajou para o Rio de Janeiro com a vinda da Corte régia para esta cidade, no segundo lote, aos cuidados do bibliotecário Luís Marrocos. Depois dos acordos que sucederam a independência do Brasil, faria parte da Biblioteca Imperial, mais tarde Biblioteca Nacional.Pretende-se enfatizar o estudo da taxionomia empreendida pelo colecionador em relação aos opúsculos, destacando as principais questões que norteiam a abordagem deste corpo de documentos. São mais de três mil folhetos entre muitos impressos e alguns manuscritos, produzidos entre os séculos XVI e XVIII, agrupados em 145 volumes existentes na seção de obras raras da Biblioteca Nacional do Brasil. Por isso abordamos também neste artigo os vários tempos percorridos por esta documentação, em suas várias concepções de história: o período de publicação dos folhetos, a clas-
