Computerized artificial intelligence (AI) decision support systems significantly improve physicians' diagnostic accuracy for bladder cancer treatment response. This AI tool enhances consistency among healthcare providers.
Area of Science:
- Oncology
- Medical Imaging
- Artificial Intelligence in Medicine
Background:
- Accurate assessment of bladder cancer treatment response is crucial for patient management.
- Physician performance in interpreting treatment response can be variable.
- Computerized decision support systems (CDSS) offer potential to aid diagnostic accuracy.
Purpose of the Study:
- To evaluate the impact of an AI-based CDSS on physicians' diagnostic accuracy for bladder cancer treatment response.
- To analyze factors influencing diagnostic performance with and without AI assistance.
Main Methods:
- Observer study involving 17 physicians assessing bladder cancer treatment response.
- Utilized pre- and post-chemotherapy CTU scans from 123 patients.
- Compared diagnostic performance with and without the CDSS-T.
Main Results:
- Physician diagnostic accuracy significantly improved when using the CDSS-T (p = 0.002).
- Factors like case difficulty and physician experience affected performance without AI.
- CDSS-T use led to more consistent performance across observers.
Conclusions:
- AI-based decision support systems can enhance diagnostic accuracy in bladder cancer treatment assessment.
- CDSS-T has the potential to standardize physician performance.
- This technology may improve patient care by ensuring more reliable treatment response evaluations.
