We investigated statewide readmissions, costs, and outcomes associated with the surgical management of type A aortic dissection repairs at low- and high-volume centers. Methods: We identified all adult type A aortic dissection patients who underwent operative repair in the Maryland Health Services Cost Review Commission's database (2012\u20132020). Hospitals were stratified into high- (top quartile of total repairs) or low-volume centers. Results: Of the 249 patients included, 193 (77.5%) were treated at a high-volume center. Patients treated at high- and low-volume centers had no differences in age, sex, race, primary payer, or severity (all p &gt; 0.5). High- compared to low-volume centers had a greater proportion of patients transferred in (71.5% vs. 17.9%, p &lt; 0.001). High-volume centers also had longer lengths of stay (12 vs. 8 days, p &lt; 0.001), similar inpatient mortality (13.0% vs. 16.1%, p = 0.6), and similar proportion of patients readmitted (54.9% vs. 51.8%, p = 0.7). High-volume centers had greater index admission costs ($114,859 vs. $72,090, p &lt; 0.001) and similar readmission costs ($48,367 vs. $42,204, p = 0.5). At high-volume centers, transferred patients compared to direct admissions had greater severity of illness (p = 0.05), similar mortality (p = 0.53), and greater lengths of stay (p = 0.05). Conclusions: High-volume centers had a greater number of patients transferred from other institutions compared to low-volume centers. High-volume centers were associated with increased index admission resource utilization, with transfer patients having higher illness severity and greater resource utilization, yet similar mortality, compared to direct admission patients.<\/jats:p>","DOI":"10.59958\/hsf.6821","type":"journal-article","created":{"date-parts":[[2023,12,14]],"date-time":"2023-12-14T00:50:51Z","timestamp":1702515051000},"page":"E694-E704","source":"Crossref","is-referenced-by-count":3,"title":["Costs and Readmissions Associated with Type A Aortic Dissections at High- and Low-Volume Centers"],"prefix":"10.31083","volume":"26","author":[{"given":"Alice L","family":"Zhou","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lekha V","family":"Yesantharao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eric W","family":"Etchill","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Iulia","family":"Barbur","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Benjamin L","family":"Shou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hamza","family":"Aziz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chun W","family":"Choi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jennifer S.","family":"Lawton","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmet","family":"Kilic","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"16242","published-online":{"date-parts":[[2023,12,13]]},"container-title":["The Heart Surgery Forum"],"original-title":[],"link":[{"URL":"https:\/\/journal.hsforum.com\/index.php\/HSF\/article\/download\/6821\/8557","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journal.hsforum.com\/index.php\/HSF\/article\/download\/6821\/8557","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,17]],"date-time":"2025-10-17T08:41:01Z","timestamp":1760690461000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.imrpress.com\/journal\/HSF\/26\/6\/10.59958\/hsf.6821"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,12,13]]},"references-count":0,"journal-issue":{"issue":"6","published-online":{"date-parts":[[2023,11,6]]}},"URL":"https:\/\/doi.org\/10.59958\/hsf.6821","relation":{},"ISSN":["1522-6662","1098-3511"],"issn-type":[{"value":"1522-6662","type":"electronic"},{"value":"1098-3511","type":"print"}],"subject":[],"published":{"date-parts":[[2023,12,13]]}}}
