Objective:

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.
