AGREE GRS Instrument

The AGREE Global Rating Scale Instrument (AGREE GRS) is a short item tool to evaluate the quality and reporting of practice guidelines.  It is based on the AGREE II, and includes the following items for assessment:

  1. Overall quality of guideline development methods
  2. Overall quality of guideline presentation
  3. Completeness of reporting
  4. Overall quality of guideline recommendations
  5. Overall quality of the guideline

The AGREE GRS Instrument was developed and evaluated through the AGREE Next Steps program of research and a paper describing the study is published in the Journal of Clinical Epidemiology.

Although the AGREE II Instrument remains the recommended appraisal tool, the AGREE GRS is a reasonable alternative for practice guideline assessment, especially in circumstances when time and resources are limited.


*The GRS is pre-fixed by “AGREE II” to relate it to the AGREE Enterprise and to distinguish it from other global rating scales that exist (i.e., the UK-GRS, the endoscopy Global Rating Scale Canada (GRS-C))
