Data on the drivers of readmission have largely been derived from single-center studies focused on a single surgical procedure with uncertainty regarding generalizability.<h4>Methods</h4>We undertook an international (28 centers, 14 countries) prospective cohort study of a representative sample of adults ≥45 years of age who underwent noncardiac surgery. Risk factors for readmission were assessed using Cox regression (ClinicalTrials.gov, NCT00512109).<h4>Results</h4>Of 36,657 eligible participants, 2744 (7.5%; 95% confidence interval [CI], 7.2-7.8) were readmitted within 30 dayAnnals of surgery open : perspectives of surgical history, education, and clinical approachese417https://www.ebi.ac.uk/biostudies/studies/S-EPMC11192008biostudies-literatureRisk Factors for Hospital Readmission Following Noncardiac Surgery: International Cohort Study.PMC11192008McGillion MHBorges FKPettit SMPatel ASimunovic MRConen DSessler DIPeter ETandon VElias FDevereaux PJWhitmore CColeman BLOuellette CMarcucci MBird MCarter NMLounsbury JCarroll SLOfori SCafaro TWatt-Watson JBedini DMMetcalfe KGauthier LPHenry SHarlock JARapanos TForbes SHeels-Ansdell DfalseRisk Factors for Hospital Readmission Following Noncardiac Surgery: International Cohort Study.<h4>Objective</h4>To determine timing and risk factors associated with readmission within 30 days of discharge following noncardiac surgery.<h4>Background</h4>Hospital readmission after noncardiac surgery is costly.
