Australia has a population of over 25 million people, with an estimated 29% of people born overseas. Previous studies have estimated the prevalence of HS in Australia to be approximately 0.67%, but methodological issues limit the accuracy of this estimate. This study was a part of the Global Hidradenitis Suppurativa Atlas (GHiSA) initiative, aiming to objectively quantify the prevalence of HS in Australia. Methods: The methodology followed the previously published GHiSA methodology. A validated questionnaire was used to identify patients likely to have a diagnosis of HS. Screen-positive patients as well as a selection of screen-negative patients underwent clinical examination by a single physician experienced in the identification, diagnosis and management of HS to further validate the sensitivity and specificity of the questionnaire. Results: A total of 1,657 eligible healthy accompanying adults were approached, of whom 1,002 consented for inclusion in the study (60.5%). A total of 9 were survey screen-positive for HS, representing a prevalence of 0.9% (95% CI: 0.5%\u20131.7%). Conclusions: This single tertiary referral center study identified an HS prevalence of 0.9% in Australia. The methods address the deficiencies in other methodologies and provide insight into the prevalence of HS globally as part of the GHiSA initiative. &lt;\/p&gt;<\/jats:p>","DOI":"10.1159\/000540455","type":"journal-article","created":{"date-parts":[[2025,7,7]],"date-time":"2025-07-07T12:02:53Z","timestamp":1751889773000},"page":"14-18","source":"Crossref","is-referenced-by-count":2,"title":["Diagnostic Accuracy of a Questionnaire Screening Test in Assessing the Prevalence of Hidradenitis Suppurativa in Sydney, Australia"],"prefix":"10.1159","volume":"241","author":[{"given":"James","family":"Pham","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akshay","family":"Flora","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emily Kay","family":"Kozera","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cecilia E.","family":"Medianfar","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8969-7144","authenticated-orcid":false,"given":"Dorra","family":"Bouazzi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robin","family":"Christensen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0712-2540","authenticated-orcid":false,"given":"Gregor B.E.","family":"Jemec","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John W.","family":"Frew","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2025,7,7]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1111\/ajd.13910"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1159\/000503605"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1111\/ajd.12287"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016\/j.jid.2020.06.019"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1016\/j.jdin.2020.05.005"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1177\/2050312118769211"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1177\/0840470421994139"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1111\/ijd.16163"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1111\/jdv.16677"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1111\/ajd.13870"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1111\/ajd.12697"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0200683"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1159\/000536389"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1111\/bjd.12787"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-4362.1999.00856.x"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1111\/bjd.19435"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.2340\/actadv.v103.4410"}],"container-title":["Dermatology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000540455","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,16]],"date-time":"2025-10-16T16:01:41Z","timestamp":1760630501000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000540455"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,7,7]]},"references-count":17,"journal-issue":{"issue":"Suppl. 1","published-online":{"date-parts":[[2025,10,16]]}},"URL":"https:\/\/doi.org\/10.1159\/000540455","archive":["Portico"],"relation":{},"ISSN":["1018-8665","1421-9832"],"issn-type":[{"value":"1018-8665","type":"print"},{"value":"1421-9832","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,7,7]]}}}
