Hypothesis

Can clinical probability scoring and D-dimer testing improve the cost-effectiveness of diagnosing acute aortic syndrome?

Conclusion

Using ADD-RS>1 or ADD-RS=1 with D-dimer >500 ng/mL to select patients for CTA is cost-effective but requires further research to validate in practice.

Supporting Evidence

  • AAS requires urgent diagnosis with CTA, which is costly and carries risks.
  • Strategies using ADD-RS and D-dimer can improve diagnostic efficiency.
  • Cost-effectiveness varies significantly based on the prevalence of AAS.

Takeaway

Doctors can use a scoring system and a blood test to decide who needs a special scan for a serious heart problem, which can save money and help more people.

Methodology

A decision analytical model was developed to simulate the management of patients with possible acute aortic syndrome using clinical scoring and D-dimer testing.

Potential Biases

Potential bias in clinician judgment regarding patient risk assessment for AAS.

Limitations

The study did not assess how clinicians determine the need for testing and excluded patients unlikely to benefit from surgery.

Participant Demographics

The hypothetical population had a mean age of 63 years, with a prevalence of AAS estimated at 0.26%.
