“When and Why” of Using an EBPH Approach

Evidence-based practice is also referred to as “best evidence.” The terminology is important because it emphasizes that it is the quality of evidence that is of primary significance, not the quantity, that is, it is the “best” information that is sought on a particular topic of interest, not the “most” information.


Why is it important to use a best-evidence approach?

Using an EBPH approach can be beneficial because it:

  • provides assurance that decision making is based on scientific evidence and effective practices;
  • helps ensure the retrieval of up-to-date and reliable information about what works and doesn’t work for a particular public health question;
  • provides assurance that one’s time is being used most efficiently and productively in reviewing the “best of the best” information available on the particular public health question.

When is it important to use a best-evidence approach?

A best-evidence approach can be used:

  • when it’s important to have scientific evidence to support decision making;
  • when evaluating the effectiveness and cost benefits of health programs;
  • when implementing new health programs;
  • when establishing new policies; and
  • when conducting literature reviews for grant projects.
