What is Clinical Trial Study?
Clinical trials are the study done for research investigations in which few individuals are selected to undergo a test for new treatments. Some of these trials are done to prevent, detect, treat, or manage various serious diseases or medical conditions.
According to WHO,” a clinical trial is any research study that prospectively assigns human participants or groups of humans to one or more health-related interventions to evaluate the effects on health outcomes.”
What it includes?
It includes experimental drugs, cells and other biological products, vaccines, medical devices, surgical and other medical treatments and procedures, health service changes, preventive care strategies, and educational interventions. But, it is not limited to these interventions. There are many other studies going on.
Why is it needed?
As long as we do clinical trial studies, there is less chance of medical errors. With every trial, we overcome errors. And at the last, we will be able to achieve precise results. Without clinical trials, we might not determine how effective is the new medical equipment developed in the lab and we cannot trust 100% on the diagnostic tests done on animals. Thus, it is required to do clinical trial research for any medical devices or diagnostic tests to ensure effectiveness and success.
Overall, these research studies seem to improve health care services by raising standard treatments. Undergoing these trials, many times has led to new interventions that will help people to live longer and to have less pain or disability.
