Evidence-Informed Public Health (EIPH)

  • Public health professionals live in a world of heavy workloads, inadequate staffing and insufficient dedicated resources.

  • Especially in the face these realities, critical appraisal of existing evidence is fundamental to the search for quality evidence to inform the process of public health decision-making.


What is evidence informed public health eiph

What is “Evidence-Informed Public Health (EIPH)”

  • EIPH is rooted in evidence-based medicine (EBM)

  • What is EBM?

    • "Evidence-based medicine is the conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patients"

    • It is a process which combines the individual doctor's expertise, the best available external clinical evidence and the patient's preferences when making decisions about the patient's health care.


Evidence informed public health

EBPH:

  • The expansion of EBM to include evidence-based public health (EBPH) is defined as:

    “The process of integrating science-based interventions with community preferences to improve the health of populations.”

Evidence-Informed Public Health (EIPH)

  • Evidence-Informed Public Health (EIPH) depends on good sound evidence.

  • Although decisions to develop and implement new programs and services must be grounded in best practices, the methods and frameworks needed to inform knowledge and translate evidence into practice are often considered time-consuming and difficult to understand.

Critical appraisal is the evidence good enough

Critical Appraisal – Is the Evidence Good Enough?

  • It has been estimated that less than 20% of published literature is scientifically sound, leaving health practitioners with the often overwhelming task of sorting the valid, sound and useful literature from the invalid and ineffectual.

  • So, how can public health professionals decide if the evidence they find is good enough?

  • The answer lies in a critical appraisal of the research evidence.


The three questions for critical appraisal

The Three Questions for Critical Appraisal:

  • Three questions need to be answered for the purpose of critically appraising research specific to public health practice :

    1. Is the research valid, sound and applicable to my situation?

    2. What outcomes can I expect if I implement this research?

    3. Will my target population be able to use this research?

Critical Appraisal Toolsfor Public Health Practice


Critical appraisal

Critical Appraisal

  • Researchers and public health physicians are encouraged to use the best available evidence in developing, implementing and evaluating public health interventions, programs, and policies to make informed decisions and get support for public health programs from community leaders and the public.

  • Purposes also include keeping up to date with current evidence, and improving research skills.


Critical appraisal tools

Critical Appraisal Tools

  • Critical appraisal include the use of users’ guides to assess the rigor/strength of research; standardized methods of quality assessment of primary studies and reviews of evidence; and up-to-date and easy-to-use tools to rate the quality of evidence/research.

  • The compendium of tools can assist with this critical appraisal.
