Episode 9: Randomisation in Clinical Trials

In this QCast episode, Jullia and Tom break down randomisation in clinical trials—why it matters, how different methods work, and what safeguards keep allocations fair and consistent across sites. They cover simple, block, and stratified randomisation, touch on unequal allocation and adaptive designs, and share a practical case study from a 5-arm trial. 

Key Takeaways

• Randomisation reduces bias, supports blinding, and strengthens trial validity.
• Simple, block, and stratified methods suit different trial sizes and needs.
• Unequal allocation and adaptive designs require clear rationale and oversight.
• Centralised systems keep assignments consistent and unpredictable across sites.
• Strong planning, role separation, and quality control ensure reliable execution.
