摘要

Robot-assisted surgical techniques have enhanced surgical precision, control, stability, and vision, particularly in cardiac interventions. However, the relationship between hospital volume and the clinical and readmission outcomes of robot-assisted cardiac surgery remains undefined. This retrospective cohort study analyzed Nationwide Readmissions Database (NRD) data from 2010 to 2020. Patients who underwent various cardiac procedures were categorized into three groups based on hospital volume of robot-assisted cardiac surgery: low-volume centers (LVCs), medium-volume centers (MVCs), and high-volume centers (HVCs). Our primary outcome variables of interest were the incidence of perioperative complications, 30-day readmission, and in-hospital mortality. 10,543 patients were included in the analysis. Compared with those treated in LVCs, the adjusted OR of 30-day readmission [OR, 0.70; (95% CI 0.53–0.92), P = 0.014] was lower in HVCs. However, higher perioperative bleeding rates were observed in MVCs (OR, 1.38; (95% CI 1.14–1.66), P = 0.001) and HVCs (OR, 1.84; (95% CI 1.52–2.21), P = 0.001). No significant differences were found in in-hospital mortality. Our research demonstrated that higher hospital surgical volume was associated with better outcomes in robot-assisted cardiac surgery, despite higher perioperative bleeding rates.
