PROBLEM: Question: Are tools for assessing the content of guidelines needed to enable their effective use -- a systematic comparison?
Answer: None of the tools analyzed enables the structured and comprehensive assessment of the content of guideline recommendations with special regard to their reliability and validity. All tools contribute towards the judicious use of evidence syntheses by supporting their systematic development or assessment. However, further progress is needed, particularly with regard to the assessment of content quality. This includes comprehensive operationalization and documentation of the assessment process to ensure reliability and validity, and therefore to enable the effective use of trustworthy guidelines in the health care system.

SOLUTION:
yes
