In the new system, a donor sequence number (DSN) was provided signifying the position of a recipient on the list for a particular donor. Whether high DSN donors have equivalent outcomes is unknown.<\/jats:p>\n <\/jats:sec>\n \n Methods and Results<\/jats:title>\n \n The United Network for Organ Sharing database was queried between May 2007 and March 2014. DSNs were divided into cohorts of 5 (sequence 1\u20135, 6\u201310, and so forth). Survival was analyzed by Kaplan-Meier method. In this dataset, 12\u2009363 adult de novo heart transplants were performed, and the median DSN was 3 with 58.3% of donors allocated locally. The distance from donor to transplant hospital was \u2264500 miles in 93.8% of cases. With increasing DSN group, recipients were older, with longer ischemic time, and higher distance (\n P<\/jats:italic>\n <0.001 for all comparisons). As well, with increasing DSN, donors were increasingly older, female sex, mismatched gender (female donor with a male recipient), lower ejection fraction, hypertensive, and had a history of smoking, alcohol, or cocaine use. For the whole cohort, the 1-year and 5-year survivals were 89.7% and 74.8%, respectively. Survival based on various cut points of DSN was investigated; there was no difference regardless of DSN.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Most donors since 2007 were allocated within a close geographic range. DSN functions as a crowdsourced rank with most donors being selected within low numbers. Given the similar survival of donors at higher DSN, this represents an opportunity to increase transplant volumes.<\/jats:p>\n <\/jats:sec>","DOI":"10.1161\/circheartfailure.118.005823","type":"journal-article","created":{"date-parts":[[2019,5,20]],"date-time":"2019-05-20T09:00:17Z","timestamp":1558342817000},"update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":19,"title":["What Number Are We?"],"prefix":"10.1161","volume":"12","author":[{"given":"David A.","family":"Baran","sequence":"first","affiliation":[{"name":"Advanced Heart Failure Center, Sentara Heart Hospital, Norfolk, VA (D.A.B.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hannah","family":"Copeland","sequence":"additional","affiliation":[{"name":"Cardiothoracic Surgery, University of Mississippi Medical Center, Jackson (H.C.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jack","family":"Copeland","sequence":"additional","affiliation":[{"name":"Cardiothoracic Surgery, University of Arizona, Tucson (J.C.)."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.healun.2015.10.023"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.healun.2016.08.017"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCHEARTFAILURE.112.000165"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1111\/ajt.13055"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2015.09.073"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.athoracsur.2005.01.022"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.healun.2005.03.014"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.1067\/mtc.2003.62"},{"key":"e_1_3_3_10_2","first-page":"735","article-title":"The alternate recipient list for heart transplantation: does it work?","volume":"16","author":"Laks H","year":"1997","unstructured":"Laks, H, Scholl, FG, Drinkwater, DC, Blitz, A, Hamilton, M, Moriguchi, J, Fonarow, G, Kobashigawa, J.
