- W4385492564 abstract "Off-pump coronary artery bypass grafting (OPCAB) has been used to mitigate the negative systemic effects of cardiopulmonary bypass. Recent consortium and single-institution studies suggest an association between operator experience and long-term survival. We thus aimed to ascertain the relationship between institutional OPCAB volume and outcomes using a contemporary nationwide all-payer database.Adult admissions for elective isolated OPCAB were identified from the 2016-2019 Nationwide Readmissions Database. The primary outcome was major adverse events (MAE), defined as a composite of mortality, reoperation, prolonged mechanical ventilation, acute kidney injury requiring dialysis, or perioperative stroke during the index hospitalisation. Secondary outcomes included temporal trends, postoperative length of stay (pLOS), hospitalisation costs, non-home discharge, and 30-day readmission rate. High-volume hospitals (HVH) were defined to have annual caseloads >35 based on cubic spline analysis.Of an estimated 41,154 patients, 59.9% were treated at HVH. The proportion of coronary artery bypass grafting operations that were OPCAB significantly decreased from 21.1% in 2016 to 18.3% in 2019. After adjustment, HVH status was associated with lower adjusted odds of MAE (adjusted odds ratio [AOR] 0.78, 95% confidence interval [CI] 0.70-0.88), compared to others. HVH were also associated with shorter pLOS (β -0.10, 95% -0.13, -0.07), reduced costs (β -US$4,900, - US$6,300, - US$3,600), non-home discharge (AOR 0.54, 95% CI 0.45-0.64), and 30-day readmission (AOR 0.86, 95% CI 0.77-0.96).Our results suggest that OPCAB requires a distinct set of surgical expertise and institutional aptitude. As a result, centralisation of care to centres of excellence should be considered." @default.
