We hypothesised that: sonographers\u2019 confidence in visualising the appendix in children was poor, particularly outside predominantly paediatric practice; workplace support for prolonging examinations to improve visualisation was limited; and the sonographic criteria applied in diagnosis did not reflect contemporary literature.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A cross\u2010sectional survey of Australasian sonographers regarding paediatric appendicitis was conducted using a mixed methods approach (quantitative and qualitative data). Text responses were analysed for key themes, and quantitative data analysed using chi\u2010square, Mann\u2013Whitney <jats:italic>U<\/jats:italic> and Wilcoxon signed\u2010rank tests.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of the 124 respondents, 27 (21.8%) reported a visualisation rate of less than 10%. Workplace support for extending examination time was significantly related to a higher appendix visualisation rate (<jats:italic>\u03c7<\/jats:italic><jats:sup>2<\/jats:sup>(2)\u00a0=\u00a016.839, <jats:italic>P\u00a0<\/jats:italic>&lt;\u00a00.001). Text responses reported frustration locating the appendix and a desire for more time and practice to improve visualisation. Sonographers suggested a significantly lower maximum diameter cut\u2010off in a 5\u2010year\u2010old compared to a 13\u2010year\u2010old (<jats:italic>Z\u00a0<\/jats:italic>=<jats:italic>\u00a0<\/jats:italic>\u22126.07, <jats:italic>P\u00a0<\/jats:italic>&lt;<jats:italic>\u00a0<\/jats:italic>0.001), and considered the presence of inflamed peri\u2010appendiceal mesentery as the most useful sonographic criterion in diagnosing acute appendicitis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Respondents had a low opinion of their ability to confidently identify the appendix. Confidence was greater in those centres where extending scanning time was encouraged. Application of echogenic mesentery as the most significant secondary sonographic criterion is supported by recent studies. Opinions of diameter cut\u2010offs varied, indicating potential for improved awareness of recent research.<\/jats:p><\/jats:sec>","DOI":"10.1002\/jmrs.310","type":"journal-article","created":{"date-parts":[[2018,10,29]],"date-time":"2018-10-29T06:29:41Z","timestamp":1540794581000},"page":"267-274","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Paediatric appendiceal ultrasound: a survey of Australasian sonographers\u2019 opinions on examination performance and sonographic criteria"],"prefix":"10.1002","volume":"65","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1843-1602","authenticated-orcid":false,"given":"Tristan","family":"Reddan","sequence":"first","affiliation":[{"name":"Medical Imaging and Nuclear Medicine Lady Cilento Children's Hospital Children's Health Queensland Hospital and Health Service South Brisbane Queensland Australia"},{"name":"Science and Engineering Faculty Queensland University of Technology Brisbane Queensland Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jonathan","family":"Corness","sequence":"additional","affiliation":[{"name":"Medical Imaging and Nuclear Medicine Lady Cilento Children's Hospital Children's Health Queensland Hospital and Health Service South Brisbane Queensland Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fiona","family":"Harden","sequence":"additional","affiliation":[{"name":"Hunter Industrial Medicine Maitland New South Wales Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kerrie","family":"Mengersen","sequence":"additional","affiliation":[{"name":"Science and Engineering Faculty Queensland University of Technology Brisbane Queensland Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2018,10,28]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/jmrs.154"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s13244-016-0469-6"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(12)60815-0"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.5409\/wjcp.v4.i2.19"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jviscsurg.2016.08.011"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10140-004-0331-x"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1055\/s-0037-1599119"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1007\/s13244-013-0275-3"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jemermed.2017.01.003"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.184.1.01840091"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1111\/ans.12415"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00383-015-3669-0"},{"key":"e_1_2_8_14_1","doi-asserted-by":"publisher","DOI":"10.1542\/peds.2012-1665"},{"key":"e_1_2_8_15_1","doi-asserted-by":"publisher","DOI":"10.1053\/j.sempedsurg.2016.05.001"},{"key":"e_1_2_8_16_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00247-012-2358-6"},{"key":"e_1_2_8_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpedsurg.2016.09.009"},{"key":"e_1_2_8_18_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00330-015-3639-x"},{"key":"e_1_2_8_19_1","doi-asserted-by":"publisher","DOI":"10.1002\/sono.12068"},{"key":"e_1_2_8_20_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpedsurg.2016.11.045"},{"key":"e_1_2_8_21_1","doi-asserted-by":"publisher","DOI":"10.14366\/usg.17062"},{"key":"e_1_2_8_22_1","doi-asserted-by":"publisher","DOI":"10.1002\/j.2205-0140.2015.tb00044.x"},{"key":"e_1_2_8_23_1","unstructured":"Australian Sonographer Accreditation Registry.Sonographer Statistics 2016[Internet].
