The primary outcome was CIED implantation in arrhythmia, cardiomyopathy, and syncope groups (and subcategories) among rural and regional residents. Secondary outcomes included CIED subtypes: pacemaker (PPM), implantable defibrillator (ICD) and cardiac resynchronisation therapy (CRT), examination of 10-year implant trends, and 5-year mortality rates adjusted for age and comorbidities.\nResults: Of the 1,291,258 cardiovascular admissions, 880,972 patients were from major cities (urban), 304,961 from inner regional (regional), and 105,325 from outer regional, rural, or remote areas (rural). Regional and rural patients received less PPMs (regional: aOR = 0.66; 95% CI 0.64\u20130.69; rural: aOR = 0.75; 95% CI 0.71\u20130.79), CRTs (regional: aOR = 0.71; 95% CI 0.65\u20130.78, rural: aOR = 0.72; 95% CI 0.83\u20130.94), and ICDs for regional patients (aOR = 0.72; 95% CI 0.67\u20130.77). Differences persisted in subcategories, including PPMs for complete heart block (regional: aOR = 0.58; 95% CI 0.56\u20130.60, rural: aOR = 0.66; 95% CI 0.62\u20130.70) and ICDs for ischaemic (regional: aOR = 0.44; 0.34\u20130.56, rural: aOR = 0.74; 95% CI 0.54\u20130.99) and non-ischaemic cardiomyopathy (regional: aOR = 0.64; 95% CI 0.56\u20130.73, rural: aOR = 0.72; 95% CI 0.59\u20130.87). Five-year mortality rates were higher in rural patients receiving PPM (urban = 23.7%; 95% CI23.2\u201324.2, rural = 26.4%; 95% CI 25.8\u201327.0), ICD (urban = 29.5%; 95% CI 28.2\u201330.7, rural = 32.5%; 95% CI 31.3\u201333.8) and CRT (urban = 24.2%; 95% CI 22.9\u201325.5, rural = 26.9%; 95% CI 25.5\u201328.3).\nConclusion: Regional and rural patients had less CIED implantation, with higher 5-year rural mortality rates. Our study highlights the geographical disparity that occurs for patients requiring CIED and the need for further examination to determine the underlying causes and address these inequities.<\/jats:p>","DOI":"10.5334\/gh.1503","type":"journal-article","created":{"date-parts":[[2025,12,10]],"date-time":"2025-12-10T10:03:32Z","timestamp":1765361012000},"page":"109","source":"Crossref","is-referenced-by-count":1,"title":["Urban-Rural Disparity in Cardiac Implantable Electronic Device Use: A 10-Year Statewide Cohort"],"prefix":"10.5334","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8115-3874","authenticated-orcid":false,"given":"Kenneth K.","family":"Cho","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1914-5918","authenticated-orcid":false,"given":"Edel","family":"O\u2019Hagan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-0110-5402","authenticated-orcid":false,"given":"Brodie","family":"Sheahen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sameer","family":"Karve","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3720-9655","authenticated-orcid":false,"given":"Natasha","family":"Nassar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1809-7846","authenticated-orcid":false,"given":"Andrew","family":"Wilson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tim","family":"Badgery-Parker","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4693-0038","authenticated-orcid":false,"given":"Clara K.","family":"Chow","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3285","published-online":{"date-parts":[[2025,12,10]]},"reference":[{"issue":"10","key":"key20251210100328_B1","doi-asserted-by":"crossref","first-page":"1123","DOI":"10.1016\/j.hlc.2018.06.1042","article-title":"National Heart Foundation of Australia and Cardiac Society of Australia and New Zealand: guidelines for the prevention, detection, and management of heart failure in Australia 2018","volume":"27","year":"2018","journal-title":"Heart Lung Circ"},{"issue":"1","key":"key20251210100328_B2","doi-asserted-by":"crossref","first-page":"71","DOI":"10.1093\/europace\/euab232","article-title":"2021 ESC guidelines on cardiac pacing and cardiac resynchronization therapy: developed by the task force on cardiac pacing and cardiac resynchronization therapy of the European Society of Cardiology (ESC) with the special contribution of the European Heart Rhythm Association (EHRA)","volume":"24","year":"2022","journal-title":"EP Europace"},{"issue":"3","key":"key20251210100328_B3","doi-asserted-by":"crossref","first-page":"267","DOI":"10.1016\/j.jacc.2021.10.045","article-title":"Rural-urban disparities in outcomes of myocardial infarction, heart failure, and stroke in the United States","volume":"79","year":"2022","journal-title":"J Am Coll Cardiol"},{"issue":"24","key":"key20251210100328_B4","doi-asserted-by":"crossref","first-page":"5126","DOI":"10.3390\/ijerph16245126","article-title":"Challenges in managing acute cardiovascular diseases and follow up care in rural areas: a narrative review","volume":"16","year":"2019","journal-title":"Int J Environ Res Public Health"},{"issue":"8","key":"key20251210100328_B5","doi-asserted-by":"crossref","first-page":"436","DOI":"10.1177\/1010539520956446","article-title":"Rural-urban disparities in cardiovascular disease mortality among middle-age men in China","volume":"32","year":"2020","journal-title":"Asia Pac J Public Health"},{"issue":"4","key":"key20251210100328_B6","doi-asserted-by":"crossref","first-page":"525","DOI":"10.2169\/internalmedicine.4660-20","article-title":"Regional disparities in adherence to guidelines for the treatment of chronic heart failure","volume":"60","year":"2021","journal-title":"Inter Med"},{"key":"key20251210100328_B7","unstructured":"Australian Bureau of Statistics.
