IWRS/IRT/RTSM: Are they different or the same?

"Clinical trials are not at all easy – they’re quite complex, lengthy, and challenging due to the rise of global regulatory norms. Before starting a clinical trial and while running it, organisations face a number of challenges, and clinical data managers need to keep themselves updated with the latest technologies and accompanying acronyms.

Some of these procedural acronyms are industry recognized, others are specific to internal operations. Some technologies that most clinical teams get confused about – IWRS, IRT, RTSM ー are they different or the same with a different name?
We wanted to provide an insight into the evolution of some commonly used acronyms in the clinical trials industry and demystify the confusion related to these critical terms."
