Results: Eighteen thousand five hundred ninety-nine CAS interventions were identified. The top 25% was used to define high-volume hospitals (&gt;60 CAS\/2 years) and practitioners (&gt;30 CAS\/2 years). The stroke rate after CAS was significantly different between low- and high-volume hospitals (2.35% vs 1.78%, respectively; P = .0206). The stroke rate after CAS was also significantly different between low- and high-volume practitioners (2.19% vs 1.51%, P = .0243). Hospital resource use varied significantly between low- and high-volume hospitals (length of stay [LOS]: 1.64 \u00b1 2.10 vs 1.45 \u00b1 11.21, P = .0006; total charges: $32 261 \u00b1 20 562 vs $30 131 \u00b1 19 592, P = .0047) and practitioners (LOS: 1.70 \u00b1 2.14 vs 1.36 \u00b1 1.36; P &lt; .0001; total charges: $33 762 \u00b1 21 081 vs $23 957 \u00b1 19 713; P &lt; .0001). Conclusions: This analysis demonstrates that hospital and physician volume are associated with outcomes and utilization after CAS. High-volume hospitals and practitioners were associated with lower procedure stroke rates and decreased hospital resource utilization.<\/jats:p>","DOI":"10.1177\/1538574409354653","type":"journal-article","created":{"date-parts":[[2009,12,3]],"date-time":"2009-12-03T20:18:50Z","timestamp":1259871530000},"page":"89-94","source":"Crossref","is-referenced-by-count":33,"title":["Carotid Artery Stenting in the Nation: The Influence of Hospital and Physician Volume on Outcomes"],"prefix":"10.1177","volume":"44","author":[{"given":"Todd R.","family":"Vogel","sequence":"first","affiliation":[{"name":"Division of Vascular Surgery, UMDNJ-Robert Wood Johnson Medical School, The Surgical Outcomes Research Group, New Brunswick, New Jersey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Viktor Y.","family":"Dombrovskiy","sequence":"additional","affiliation":[{"name":"Division of Vascular Surgery, UMDNJ-Robert Wood Johnson Medical School, The Surgical Outcomes Research Group, New Brunswick, New Jersey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alan M.","family":"Graham","sequence":"additional","affiliation":[{"name":"Division of Vascular Surgery, UMDNJ-Robert Wood Johnson Medical School, The Surgical Outcomes Research Group, New Brunswick, New Jersey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2009,12,2]]},"reference":[{"key":"atypb1","doi-asserted-by":"publisher","DOI":"10.1016\/S0741-5214(99)70202-8"},{"key":"atypb2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2008.03.033"},{"key":"atypb3","doi-asserted-by":"publisher","DOI":"10.1016\/S1072-7515(02)01345-5"},{"key":"atypb4","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(06)69122-8"},{"key":"atypb5","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2006.03.044"},{"key":"atypb6","doi-asserted-by":"publisher","DOI":"10.1002\/ccd.21359"},{"key":"atypb7","volume-title":"The National Hospital Bill: The Most Expensive Conditions, by Payer, 2004.
