Before exploring the benefits of synthetic data, it’s important to understand the hurdles researchers face with real-world patient data:
- Privacy restrictions: Patient health data is protected under strict laws such as HIPAA and GDPR. Sharing or reusing datasets can lead to legal and ethical complications.
- Limited access: Clinical trial data is often siloed within institutions, restricting collaboration and slowing progress.
- Data gaps: Real-world datasets are rarely complete or diverse, which leads to bias in models and limits generalizability.
- Time and cost: Collecting, cleaning, and preparing medical data for research consumes years and millions of dollars.
For an industry under pressure to bring therapies to market faster, these limitations create a bottleneck that synthetic data can help eliminate.
