Developing an Evidence Base

In order to determine the effectiveness of a health intervention or treatment, it is important to evaluate the treatment scientifically before making it available to the general public. This process of scientific evaluation provides evidence that the intervention does what it says it will do for the population it says it will help. The results of this scientific evaluation are known as an evidence base.

In order to determine the effectiveness of a health intervention or treatment, it is important to evaluate the treatment scientifically before making it available to the general public.

The major component of an evidence base comes from the results of a well-designed scientific study. The gold standard of scientific studies is the randomized controlled trial, in which people with a specific condition are randomly assigned to receive the treatment being studied or to continue with their usual medical care. If the results of the group that received the treatment are better than the results of the group that did not receive the treatment, it can be said that the treatment is effective.
