Critical Appraisal of Research Articles: Clinical Practice Guidelines

What is a Clinical Practice Guideline?

A clinical practice guideline is a systematically developed statement designed to help health care professionals make decisions about appropriate health care for specific clinical circumstances.

Guidelines attempt to do this by:

  • Describing a range of generally accepted approaches for the diagnosis, management, or prevention of specific diseases or conditions.

  • Defining practices that meet the needs of most patients in most circumstances.

Clinical Practice Guidelines

Find Clinical Practice Guidelines:

1. Search the ECRI Guidelines Trust.

2. Go to ClinicalKey and limit the search to "Guidelines".

3.  When searching MEDLINE, click on "Additional Limits", and limit by publication type (Practice Guideline).

  • Have the target users of the guideline been clearly defined?
  • Has the guideline been piloted among target users?

Rigour of Development

  • Were systematic methods used to search for evidence?

  • Were the methods used for formulating the recommendations clearly described?
  • Were the health benefits, side effects, and risks considered in formulating the recommendations?
  • Is there an explicit link between the recommendations and the supporting evidence?

Clarity and Presentation

  • Are the recommendations specific and unambiguous?

  • Are key recommendations clearly identifiable?
  • Is the guideline supported with tools for application?

Applicability

  • Have the potential organization barriers in applying the recommendation been discussed?
  • Have the potential cost implications of applying the recommendations been considered?
  • Does the guideline present key review criteria for monitoring and/or auditing purposes?

Editorial Independence

  • Is the guideline editorially independent from the funding body?
  • Have conflicts of interest of guideline development members been recorded?

Appraisal of Clinical Practice Guidelines

The AGREE (Appraisal of Guidelines for Research & Evaluation) Instrument is a tool that assesses the methodological rigour and transparency in which a guideline is developed and it is used internationally.

The purpose of the AGREE Instrument is to provide a framework for assessing the quality of clinical practice guidelines.

 The AGREE Instrument is designed to assess guidelines developed by local, regional, national, or international groups or affiliated government organizations.  These include:

  1. New guidelines
  2. Existing guidelines
  3. Updates of existing guidelines
