Material and Methods
This investigation was exempt from institutional review board review at each participating center because of its deidentified nature as a quality database and because of the absence of Health Insurance Portability and Accountability Act patient identifiers.
Patient Characteristics, Operative Features, and Outcomes for CABG ± AVR
Table 1 reports patient characteristics and operative features for all patients undergoing both CABG alone and CABG + AVR. Patients undergoing combined CABG + AVR were on average older, were more commonly female, and presented with increased operative risk for mortality as determined by the presence of baseline comorbid disease and median STS PROM scores in comparison with patients undergoing CABG alone. Cardiopulmonary bypass support was used in 92% of CABG alone operations. Prior CABG and
Comment
The present study reports outcomes, hospital resource utilization, and costs among a multiinstitutional, statewide cohort of patients undergoing CABG with or without concomitant AVR. The reported data represent a 10-year collaborative experience of the VCSQI. The principal findings of this study relate to the impact of postoperative complications on hospital resource utilization and the risk-adjusted incremental costs of hospitalization. Consequently, the results of this study serve to quantify

2022, Annals of Thoracic SurgeryCitation Excerpt :Postoperative outcomes, including mortality, LOS, and complications, were associated with HRU in our multivariable analysis. Previous studies demonstrated a strong association between postoperative infection and costs in open heart and abdominal surgery.29-33 Infectious complications had the highest adjusted odds for HRU (AOR, 4.06) in our study.
Drivers of Cost Associated With Minimally Invasive Esophagectomy
2022, Annals of Thoracic SurgeryCitation Excerpt :The implementation of standardized enhanced recovery pathways after lobectomy and open esophagectomy have shown associations with lower postoperative morbidity and LOS24,25; both are independent drivers of cost. In the Virginia Cardiac Surgery Quality Improvement Initiative a collaboration of health systems were successful in improving value for patients after coronary artery bypass grafting and aortic valve replacement by similarly reducing variations in postoperative care.26 Specifically the results of this study have uncovered several opportunities for cost-saving after MIE through actionable quality improvement initiatives within our institution.
