As per a study, randomization and blinding in research, despite their numerous benefits, are underutilized tools in non-pharmaceutical trials. While clinical trial organizers and researchers acknowledge the benefits of randomization and blinding, not many have been keen to implement the protocol in research studies for a long time.
However, after 2020, when decentralized clinical trials, electronic data capture, and the need for acceleration emerged in healthcare research, randomization, and blinding also garnered attention. To understand more about the clinical research method, continue to read below.
What Is Randomization and Blinding in Research?
Randomized clinical trials (RCT) is also known as randomization, placebo-controlled, and double-blinded clinical trial. Randomization in clinical trials refers to the random selection of participants. On the other hand, placebo-controlled and double-blinded refer to the method through which neither the participant nor the administrator knows if a placebo is used or the treatment.
Elements of Randomization in Clinical Trial
Here are the elements that make clinical research randomized and blinded:
- All participants are randomly recruited.
- All participants have exposure to a similar condition.
- All participants determine success on similar parameters.
- All participants are blinded during the administration of treatment or placebo.
Benefits of Randomization and Blinding
For improved clinical data, here are the benefits:
- Eliminate bias that may affect the outcomes of research.
- Improve data integrity by acquiring genuine responses.
