Optimizing Site Selection Using Historical Data

Share on TwitterShare on LinkedInShare on Facebook

Site selection is one of the most critical decisions affecting clinical trial success. Learn how to leverage historical data to make more informed site selection decisions.

The Cost of Poor Site Selection

Traditional site selection often relies heavily on:

  • Investigator relationships
  • Site experience claims
  • Geographic location

However, this approach frequently leads to:

  • 20% of sites never enrolling a single patient
  • 30% under-enrolling
  • Significant budget waste

Leveraging Historical Data

Key Performance Indicators to Consider

  1. Previous Enrollment Performance

    • Actual vs. predicted enrollment rates
    • Screen failure rates
    • Retention rates

  2. Operational Efficiency

    • Start-up timelines
    • Query resolution time
    • Protocol deviation rates

  3. Quality Metrics

    • Data entry timeliness
    • Protocol compliance
    • Audit findings

Predictive Analytics in Site Selection

Modern approaches use machine learning to:

  • Predict site performance
  • Identify risk factors
  • Optimize site mix

Key Benefits

  • Reduced site activation costs
  • Faster enrollment completion
  • Better quality data

Implementation Strategy

  1. Gather historical performance data
  2. Identify key success factors
  3. Create performance benchmarks
  4. Develop scoring system
  5. Monitor and adjust

Conclusion

Data-driven site selection leads to more predictable enrollment timelines and better study outcomes. The key is having the right tools to collect, analyze, and act on historical performance data.
