Multivariable logistic regression was used to identify factors associated with readmission. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p> Of 5,152 eligible patients, 1,003 (19.5%) were readmitted within 30 days of discharge. Mean patient age was 75 years. Diagnoses associated with readmission included infection (34.7%), dehydration (34.3%), ileus\/obstruction (26.2%), metabolic\/electrolyte derangements (23.1%), and anemia (12.3%). In multivariable analysis, year of discharge was significantly associated with 30-day readmission (1996 to 2000: odds ratio [OR], 1.32; 95% CI, 1.01 to 1.71; 2001 to 2005: OR, 1.58; 95% CI, 1.24 to 2.0; 2006 to 2010: OR, 1.73; 95% CI, 1.35 to 2.21; referent years 1992 to 1995), as were length of index hospital stay more than 8 days (OR, 1.39; 95% CI, 1.18 to 1.64) and discharge to a skilled nursing facility (OR, 1.3; 95% CI, 1.04 to 1.63). Patients readmitted within 30 days had a significantly greater 1-year mortality rate compared with patients not readmitted (41.1% v 25.1%, respectively; P &lt; .001). The median cost of readmission hospital stay was $9,220 in year 2010 dollars, with a total cost of $9.3 million over the study period. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p> Early readmission after surgery for ovarian cancer is common. There is a significant association between 30-day readmission and 1-year mortality. These findings may catalyze development of targeted interventions to decrease early readmission, improve patient outcomes, and control health care costs. <\/jats:p><\/jats:sec>","DOI":"10.1200\/jco.2014.56.7743","type":"journal-article","created":{"date-parts":[[2014,11,11]],"date-time":"2014-11-11T03:33:20Z","timestamp":1415676800000},"page":"4113-4119","source":"Crossref","is-referenced-by-count":34,"title":["Evaluation of 30-Day Hospital Readmission After Surgery for Advanced-Stage Ovarian Cancer in a Medicare Population"],"prefix":"10.1200","volume":"32","author":[{"given":"Ramez N.","family":"Eskander","sequence":"first","affiliation":[{"name":"All authors: University of California, Irvine, Irvine, CA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jenny","family":"Chang","sequence":"additional","affiliation":[{"name":"All authors: University of California, Irvine, Irvine, CA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Argyrios","family":"Ziogas","sequence":"additional","affiliation":[{"name":"All authors: University of California, Irvine, Irvine, CA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hoda","family":"Anton-Culver","sequence":"additional","affiliation":[{"name":"All authors: University of California, Irvine, Irvine, CA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert E.","family":"Bristow","sequence":"additional","affiliation":[{"name":"All authors: University of California, Irvine, Irvine, CA."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"233","reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.3322\/caac.21208"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ygyno.2011.05.011"},{"key":"B3","first-page":"76212","volume":"78","author":"Centers for Medicare and Medicaid Services, Department of Health and Human Services","year":"2013","journal-title":"Fed Regist"},{"key":"B4","first-page":"169","volume":"53","author":"Lampton LM","year":"2012","journal-title":"J Miss State Med Assoc"},{"key":"B5","doi-asserted-by":"publisher","DOI":"10.1016\/j.jamcollsurg.2012.05.024"},{"key":"B6","doi-asserted-by":"publisher","DOI":"10.1111\/j.1748-720X.2012.00684.x"},{"key":"B7","doi-asserted-by":"publisher","DOI":"10.1097\/IGC.0b013e3182157a19"},{"key":"B8","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCOUTCOMES.111.000093"},{"key":"B9","doi-asserted-by":"publisher","DOI":"10.1177\/1062860612465066"},{"key":"B10","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcin.2012.12.119"},{"key":"B11","doi-asserted-by":"publisher","DOI":"10.1002\/clc.22180"},{"key":"B12","doi-asserted-by":"publisher","DOI":"10.1097\/NCM.0b013e31824c5fca"},{"key":"B13","doi-asserted-by":"publisher","DOI":"10.1097\/00005650-200208001-00002"},{"key":"B14","doi-asserted-by":"publisher","DOI":"10.1097\/00005650-200208001-00004"},{"key":"B16","doi-asserted-by":"publisher","DOI":"10.1016\/0895-4356(92)90133-8"},{"key":"B17","doi-asserted-by":"publisher","DOI":"10.1016\/0021-9681(87)90171-8"},{"key":"B18","doi-asserted-by":"publisher","DOI":"10.1016\/S0895-4356(00)00256-0"},{"key":"B19","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejca.2012.07.023"},{"key":"B20","doi-asserted-by":"publisher","DOI":"10.1177\/1049909110392204"},{"key":"B21","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2012.11.074"},{"key":"B22","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-6143.2012.04289.x"},{"key":"B23","doi-asserted-by":"publisher","DOI":"10.1016\/j.jamcollsurg.2012.07.007"},{"key":"B24","doi-asserted-by":"publisher","DOI":"10.1016\/j.jamcollsurg.2011.12.025"},{"key":"B25","doi-asserted-by":"publisher","DOI":"10.1097\/DCR.0b013e31822ff8f0"},{"key":"B26","unstructured":"A Gawande :  The hot spotters: Can we lower medical costs by giving the neediest patients better care?
