Custom LLMs for 20% Higher Clinical Trial Patient Retention

This 33-page ECHO Report is a detailed exploration of Techdome’s custom LLM implementation that streamlines clinical trial processes, and the decisions that made it possible.

This report emphasizes the practical mechanics of scalable automation—covering model specialization, data structuring, system modularity, and human-in-the-loop feedback.

For product and engineering leaders in mid-sized to large organizations operating in data-intensive, high-stakes workflows—particularly in life sciences, healthcare tech, or other sectors with complex process automation needs – it serves as a technically detailed case study in moving from experimentation to production-grade deployment.

Key decisions

• Custom LLM + traditional ML interplay with structured handoff
• Clinician and patient feedback used for RLHF and domain finetuning
• Key-attribute mapping to enable cross-industry portability
• Real-time predictive validation at point-of-entry
• Multi-layer flagging for compliance and error handling

Key results

• 20% increase in patient engagement and retention
• 95% decrease in manual data entry errors and inconsistencies
• 25% faster time-to-market
• A 4/5 CSAT score, from 1,000 trial participants
