Description

This critical appraisal tool is used to measure the methodological rigour of clinical practice guideline development. The instrument consists of 23 items organized within six domains, followed by two global rating items for an overall assessment. Each domain captures a specific aspect of guideline development quality. AGREE II is an updated version of AGREE (2003).

Steps for Using Method/Tool

The instrument guides users through six distinct domains. Each domain includes items that are scaled from 1–7. A quality score is calculated for each of the domains, with an overall score calculated by summing all the domains. The six domains are:

  1. Scope and purpose – overall aim of the guideline
  2. Stakeholder involvement – role and expectations of stakeholders
  3. Rigour of development – gathering and summarizing the evidence
  4. Clarity of presentation – technical guidance
  5. Applicability – barriers and facilitators to implementation
  6. Editorial independence – identifying potential biases
