Despite its association with adverse events after noncardiac surgery, its impact in the context of cardiac surgery remains unclear.<\/jats:p>\n <\/jats:sec>\n \n Objective<\/jats:title>\n To compare the outcomes of patients who were exposed to anesthesia handover vs those who were unexposed to anesthesia handover during cardiac surgery.<\/jats:p>\n <\/jats:sec>\n \n Design, Setting, and Participants<\/jats:title>\n This retrospective cohort study in Ontario, Canada, included Ontario residents who were 18 years or older and had undergone coronary artery bypass grafting or aortic, mitral, tricuspid valve, or thoracic aorta surgical procedures between 2008 and 2019. Exclusion criteria were non-Ontario residency status and other concomitant procedures. Statistical analysis was conducted from April 2021 to June 2021, and data collection occurred between November 2020 to January 2021.<\/jats:p>\n <\/jats:sec>\n \n Exposures<\/jats:title>\n Complete handover of anesthesia care, where the case is completed by the replacement anesthesiologist.<\/jats:p>\n <\/jats:sec>\n \n Main Outcomes and Measures<\/jats:title>\n The coprimary outcomes were mortality within 30 days and 1 year after surgery. Secondary outcomes were patient-defined adverse cardiac and noncardiac events (PACE), intensive care unit (ICU), and hospital lengths of stay (LOS). Inverse probability of treatment weighting based on the propensity score was used to estimate adjusted effect measures. Mortality was assessed using a Cox proportional hazard model, PACE using a cause-specific hazard model with death as a competing risk, and LOS using Poisson regression.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n Of the 102\u202f156 patients in the cohort, 25\u202f207 (24.7%) were women; the mean (SD) age was 66.4 (10.8) years; and 72\u202f843 of surgical procedures (71.3%) were performed in teaching hospitals. Handover occurred in 1926 patients (1.9%) and was associated with higher risks of 30-day mortality (hazard ratio [HR], 1.89; 95% CI, 1.41-2.54) and 1-year mortality (HR, 1.66; 95% CI, 1.31-2.12), as well as longer ICU (risk ratio [RR], 1.43; 95% CI, 1.22-1.68) and hospital (RR, 1.17; 95% CI, 1.06-1.28) LOS. There was no statistically significant association between handover and PACE (30 days: HR 1.09; 95% CI, 0.79-1.49; 1 year: HR 0.89; 95% CI, 0.70-1.13).<\/jats:p>\n <\/jats:sec>\n \n Conclusions and Relevance<\/jats:title>\n Handover of anesthesia care during cardiac surgical procedures was associated with higher 30-day and 1-year mortality rates and increased health care resource use. Further research is needed to evaluate and systematically improve the handover process qualitatively.<\/jats:p>\n <\/jats:sec>","DOI":"10.1001\/jamanetworkopen.2021.48161","type":"journal-article","created":{"date-parts":[[2022,2,11]],"date-time":"2022-02-11T11:31:26Z","timestamp":1644579086000},"page":"e2148161","source":"Crossref","is-referenced-by-count":32,"title":["Association Between Handover of Anesthesiology Care and 1-Year Mortality Among Adults Undergoing Cardiac Surgery"],"prefix":"10.1001","volume":"5","author":[{"given":"Louise Y.","family":"Sun","sequence":"first","affiliation":[{"name":"Division of Cardiac Anesthesiology, University of Ottawa Heart Institute, Ottawa, Ontario, Canada"},{"name":"ICES, Ontario, Canada"},{"name":"School of Epidemiology and Public Health, University of Ottawa, Ottawa, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philip M.","family":"Jones","sequence":"additional","affiliation":[{"name":"ICES, Ontario, Canada"},{"name":"Departments of Anesthesia and Perioperative Medicine and Epidemiology and Biostatistics, University of Western Ontario, London, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Duminda N.","family":"Wijeysundera","sequence":"additional","affiliation":[{"name":"ICES, Ontario, Canada"},{"name":"Department of Anesthesiology and Pain Medicine, University of Toronto, Toronto, Ontario, Canada"},{"name":"Department of Anesthesia, St Michael\u2019s Hospital, Toronto, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mamas A.","family":"Mamas","sequence":"additional","affiliation":[{"name":"Keele Cardiovascular Research Group, Centre for Prognosis Research, Keele University and Institute for Population Health, University of Manchester, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anan","family":"Bader Eddeen","sequence":"additional","affiliation":[{"name":"ICES, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John","family":"O\u2019Connor","sequence":"additional","affiliation":[{"name":"Division of Cardiac Anesthesiology, University of Ottawa Heart Institute, Ottawa, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"10","published-online":{"date-parts":[[2022,2,11]]},"reference":[{"issue":"4","key":"zoi211324r1","doi-asserted-by":"publisher","first-page":"605","DOI":"10.1016\/j.bja.2020.05.062","article-title":"Association of intraoperative anaesthesia handovers with patient morbidity and mortality: a systematic review and meta-analysis.","volume":"125","author":"Boet","year":"2020","journal-title":"Br J Anaesth"},{"issue":"1","key":"zoi211324r2","doi-asserted-by":"publisher","first-page":"11","DOI":"10.1053\/j.jvca.2014.05.018","article-title":"Impact of anesthetic handover on mortality and morbidity in cardiac surgery: a cohort study.","volume":"29","author":"Hudson","year":"2015","journal-title":"J Cardiothorac Vasc Anesth"},{"issue":"2","key":"zoi211324r3","doi-asserted-by":"publisher","first-page":"143","DOI":"10.1001\/jama.2017.20040","article-title":"Association between handover of anesthesia care and adverse postoperative outcomes among patients undergoing major surgery.","volume":"319","author":"Jones","year":"2018","journal-title":"JAMA"},{"issue":"1","key":"zoi211324r4","doi-asserted-by":"publisher","first-page":"7","DOI":"10.1186\/s40886-018-0073-1","article-title":"Situation, background, assessment, recommendation (SBAR) communication tool for handoff in health care: a narrative review.","volume":"4","author":"Shahid","year":"2018","journal-title":"Safety Health"},{"issue":"16","key":"zoi211324r5","doi-asserted-by":"publisher","first-page":"1249","DOI":"10.1056\/NEJMsa020846","article-title":"Patient safety: fatigue among clinicians and the safety of patients.","volume":"347","author":"Gaba","year":"2002","journal-title":"N Engl J Med"},{"issue":"1","key":"zoi211324r6","doi-asserted-by":"publisher","first-page":"8","DOI":"10.1053\/j.jvca.2014.10.024","article-title":"Are intraoperative anesthesia handovers associated with harm?
