What Is IRT And How Does It Impact Clinical Trials?

Before automated systems, randomisation meant sealed envelopes, matched kit numbers, and a site-level process that worked only for simple designs and invited human error. Interactive response technology (also known as IVRS, IWRS, IXRS, or RTSM) changes that by moving randomisation, blind protection, and supply management into one centralised system. Stratified randomisation schemes, privilege-based control of unblinded data, emergency unblinding, and closed-loop resupply logic that responds as site inventory falls all come into play. The source also points to a benefit it calls often overlooked: electronic handling of drug accountability, returns, and destruction. Explore how each function shapes trial efficiency and the quality of information available during a study.
