ABSTRACT
OBJECTIVE:
To determine the relationship between volume of cases and failure-to-rescue (FTR) rate after surgery for acute type A aortic dissection (ATAAD) across the United States.METHODS:
The Society of Thoracic Surgeons adult cardiac surgery database was used to review outcomes of surgery after ATAAD between June 2017 and December 2021. Mixed-effect models and restricted cubic splines were used to determine the risk-adjusted relationships between ATAAD average volume and FTR rate. FTR calculation was based on deaths associated with the following complications venous thromboembolism/deep venous thrombosis, stroke, renal failure, mechanical ventilation >48 hours, sepsis, gastrointestinal complications, cardiopulmonary resuscitation, and unplanned reoperation.RESULTS:
In total, 18,192 patients underwent surgery for ATAAD in 832 centers. The included hospitals' median volume was 2.2 cases/year (interquartile range [IQR], 0.9-5.8). Quartiles' distribution was 615 centers in the first (1.3 cases/year, IQR, 0.4-2.9); 123 centers in the second (8 cases/year, IQR, 6.7-10.2); 66 centers in the third (15.6 cases/year, IQR, 14.2-18); and 28 centers in the fourth quartile (29.3 cases/year, IQR, 28.8-46.0). Fourth-quartile hospitals performed more extensive procedures. Overall complication, mortality, and FTR rates were 52.6%, 14.2%, and 21.7%, respectively. Risk-adjusted analysis demonstrated increased odds of FTR when the average volume was fewer than 10 cases per year.CONCLUSIONS:
Although high-volume centers performed more complex procedures than low-volume centers, their operative mortality was lower, perhaps reflecting their ability to rescue patients and mitigate complications. An average of fewer than 10 cases per year at an institution is associated with increased odds of failure to rescue patients after ATAAD repair.
