Abstract
OBJECTIVE: This study seeks to assess the safety of overlap in cardiac surgery.
METHODS: Coarsened exact matching was used to assess the impact of overlap on outcomes among cardiac surgical interventions (n = 4463) over 2 years (2014-2016). Overlap was categorized as any, beginning, or end overlap. Study subjects were matched 1:1 on 11 variables, including Charlson comorbidity score, surgical costs, body mass index, length of postoperative hospitalization, and race, among others. Serious unanticipated events were studied, including readmission, unplanned return to the operating room, and mortality.
RESULTS: A total of 984 patients had any overlap and were matched to similar patients without overlap (n = 1501). For beginning/end overlap, separate matched groups were created (n = 462, n = 329 patients, respectively). Among matched patients, any overlap did not predict unanticipated return to surgery at 30 or 90 days. Any overlap did not predict increased readmission, reoperation, or emergency department visits at 30 or 90 days. Overlap did not predict higher rates of death over follow-up. Beginning/end overlap had results similar to any overlap.
CONCLUSIONS: Nonconcurrent, overlapping surgery is not associated with an increase in adverse outcomes in a large, matched cardiac surgery population.
