PurposePreoperative multidisciplinary team (MDT) meetings are recommended for patients at high risk for perioperative complications and mortality, although the underlying evidence is scarce. We aimed to investigate the effect of MDT decisions on patient management and patient outcome.MethodsWe conducted a single-centre retrospective cohort study including all noncardiac surgical patients selected for discussion at preoperative MDT meetings from January 2017 to December 2019 (N = 120). We abstracted preoperative data, MDT decisions, and patient outcomes from the electronic health records for analysis.ResultsOf the 120 patients registered for an MDT meeting, 43% did not undergo their initially planned surgery. Only 27% of patients received perioperative management as planned before the MDT meeting. Most surgery cancellations were the MDT's decision (22%) or the patient's decision before or after the MDT discussion (10%). Postoperative complications occurred in 28% of operated patients, and postoperative mortality was 4% at 30 days and 10% at three months, most of which was attributable to postoperative complications. Non-operated patients had a 7% mortality rate at 30 days and 9% at three months. Alterations of perioperative management following MDT discussion were associated with fewer cases of extended length of hospital stay (> ten days).ConclusionThis study shows that preoperative MDT meetings for high-risk noncardiac surgical patients altered the management of most patients. Management alterations were associated with fewer hospital admissions of long duration. These results should be interpreted with appropriate caution given the methodological limitations inherent to this small study.© 2021. Canadian Anesthesiologists' Society.
