Evidence-Informed Decision-Making (EIDM)

In our jobs, we have to make decisions about many different things such as programs, policies, strategies, staffing and service delivery. We all want to make the best decisions possible for our organizations and the people we serve.

Evidence-informed decision-making (EIDM) is the process of involving the best available research evidence into the decision-making process.

The reality is that many factors influence our decisions. This model below, which has been adapted from the National Collaborating Centre for Methods and Tools (NCCMT), highlights some of the common sources of evidence that get considered in the decision-making process in the realm of health and social change efforts.


The weight and influence that each factor will have on the decision-making process depends on the specific circumstances, as well as the skills and values held by the individuals and groups involved in the process.

The placement of expertise at the centre of the model is intentional and represents the notion that decision-makers have to also draw on their implied topic-specific knowledge and expertise to incorporate all the relevant factors into the final decision or recommendation.

The four sources of evidence are described in the table below.

Sources of Evidence Examples of Evidence for Consideration
1. Evidence about the frequency, causes, and modifying factors of local community issues and context
  • Surveillance data and status reports to determine the magnitude of the issue in the local setting.
  • Significance and importance of the issue in comparison to other community issues or concerns.
2. Evidence from research
  • The most relevant, high-quality qualitative or quantitative evidence available.
  • Research findings from a variety of disciplines and sectors relevant to the issue.
3. Evidence from people about community and political preferences and actions
  • Needs and interests of community members.
  • Support/opposition from public and/or government officials.
  • Current political climate (regional, provincial, federal).
  • Current organizational/corporate climate.
4. Evidence from various places about resources
  • Financial, human resources (personnel/staffing, administrative support, support from management) materials.

Why is EIDM Important? What are the benefits to your organization?

  • Adoption of the most effective and cost-efficient interventions
  • Careful use of limited resources (e.g. money, time, human resources)
  • Better health and social outcomes for the individuals and communities served

EIDM Stages

The NCCMT has developed a thorough overview of the stages involved in EIDM and has developed supporting resources and tools for the various stages. While these resources are presented from a public health lens, they are generic enough to be applied to many other fields of practice.

Do You Have Limited Time to Review Research Evidence?

These days, many people are pressed for time and so the stages of "Appraising" and "Synthesizing" the evidence may not always be feasible to do.

In this situation, the "hierarchy of evidence" and looking for "pre-appraised" and "synthesized" evidence becomes very useful because it helps you to advance your EIDM journey to the "Adapt" stage a bit quicker. It does some of the appraisal and synthesizing for you!

By starting at the top of the evidence pyramid (as shown below) you can begin to speed up your EIDM journey! It is important to note that in several fields of practice, particularly when it comes to community–based health promotion and social change initiatives, there is less evidence at the "systems" and "summaries" level. These are more typical in clinical or medical fields of practice.

Therefore, starting your search on the pyramid at the level of "Synopses of Syntheses" tends to be most common in the field of community-based health promotion and social change efforts.
