The survey was sent by email to all members of the Swiss Societies of Rheumatology and for Allergy and Immunology. A reminder was sent to nonresponders after 4 and 12 weeks. Its questions covered the following dimensions: respondents\u2019 main characteristics, diagnosis, treatment, and imaging\u2019s role during follow-up. The main study results were summarized using descriptive statistics.\r\nRESULTS: Ninety-one specialists, primarily aged 46\u201365 years (n = 53\/89; 59%), working in academic or nonacademic hospitals or private practice, and treating a median of 7.5 (interquartile range [IQR]: 3\u201312) patients with giant-cell arteritis per year participated in this survey. Ultrasound of temporal arteries\/large vessels (n = 75\/90; 83%) and positron-emission-tomography-computed tomography (n = 52\/91; 57%) or magnetic resonance imaging (n = 46\/90; 51%) of the aorta\/extracranial arteries were the most common techniques used to diagnose giant-cell arteritis with cranial or large vessel involvement, respectively. Most participants reported a short time to obtain imaging tests or arterial biopsy. The glucocorticoid tapering scheme, glucocorticoid-sparing agent, and glucocorticoid-sparing treatment duration varied among the participants. Most physicians did not follow a predefined repeat imaging scheme for follow-up and mainly relied on structural changes (vascular thickening, stenosis, or dilatation) to drive treatment choice.\r\nCONCLUSIONS: This survey indicates that imaging and temporal biopsy are rapidly accessible for diagnosing giant-cell arteritis in Switzerland but highlights heterogeneous practice in many disease management areas.<\/jats:p>","DOI":"10.57187\/smw.2023.40051","type":"journal-article","created":{"date-parts":[[2023,4,3]],"date-time":"2023-04-03T21:08:21Z","timestamp":1680556101000},"page":"40051","source":"Crossref","is-referenced-by-count":3,"title":["Management of giant-cell arteritis in Switzerland: an online national survey"],"prefix":"10.57187","volume":"153","author":[{"given":"Michele","family":"Iudici","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrea Katharina","family":"Hemmig","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mihaela","family":"Stegert","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Courvoisier","family":"Courvoisier","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sabine","family":"Adler","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mike Oliver","family":"Becker","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christoph T.","family":"Berger","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Diana","family":"Dan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Axel","family":"Finckh","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alfred","family":"Mahr","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas","family":"Neumann","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephan","family":"Reichenbach","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Camillo","family":"Ribi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luca","family":"Seitz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter","family":"Villiger","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lukas","family":"Wildi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas","family":"Daikeler","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"On behalf of Giant Cell Arteritis SCQM Study Group","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"36756","published-online":{"date-parts":[[2023,4,3]]},"reference":[{"key":"81640","doi-asserted-by":"crossref","unstructured":"Dejaco C , Brouwer E , Mason JC , Buttgereit F , Matteson EL , Dasgupta B .
