To evaluate the impact of safety-net hospital status (defined as institutions in the top quartile of the proportion of Medicaid/uninsured) on outcomes of Stanford type A aortic dissection repairs.
Approach:
Key Findings:
Mortality rates were similar at safety-net (13%) and non-safety-net hospitals (16%), indicating comparable safety.
Median length of stay was 10 days for both hospital types, suggesting efficiency in care.
Median hospitalization costs were comparable: $81,400 at safety-net hospitals and $78,800 at non-safety-net hospitals, highlighting financial parity.
Higher procedural volume at hospitals was associated with reduced odds of death, emphasizing the importance of surgical experience.
Interpretation:
Safety-net hospitals can effectively manage type A aortic dissection repairs without increasing postoperative risks, suggesting their potential as regional providers, particularly when supported by skilled surgical teams.
Limitations:
Study focused on short-term outcomes; long-term outcomes and readmission rates were not assessed.
Underfunding and resource constraints of safety-net hospitals may still impact care quality.
Potential biases inherent in retrospective studies may affect the reliability of the findings.
Conclusion:
Safety-net hospitals can serve as regional entry points for aortic dissection repairs, emphasizing the importance of surgeon expertise over institutional resources, and highlighting the need for further research on long-term outcomes.
An ancillary analysis found less than 2-percentage-point differences in 10-year recurrence across margin thresholds, with no statistically significant adjusted association.
