Using evidence to decision frameworks led to guidelines of better quality and more credible and transparent recommendations

Abstract

BACKGROUND AND OBJECTIVES: To determine whether the use of Evidence to Decision (EtD) frameworks is associated to higher quality of both guidelines and individual recommendations. METHODS: We identified guidelines recently published by international organizations that have methodological guidance documents for their development. Pairs of researchers independently extracted information on the use of these frameworks, appraised the quality of the guidelines using the Appraisal of Guidelines, Research and Evaluation II Instrument (AGREE-II), and assessed the clinical credibility and implementability of the recommendations with the Appraisal of Guidelines for REsearch & Evaluation Recommendations Excellence (AGREE-REX) tool. We conducted both descriptive and inferential analyses. RESULTS: We included 66 guidelines from 17 different countries, published in the last 5 years. Thirty guidelines (45%) used an EtD framework to formulate their recommendations. Compared to those that did not use a framework, those using an EtD framework scored higher in all domains of both AGREE-II and AGREE-REX (P < 0.05). Quality scores did not differ between the use of the The Grading of Recommendations Assessment, Development and Evaluation-EtD framework (17 guidelines) or another EtD framework (13 guidelines) (P > 0.05). CONCLUSION: The use of EtD frameworks is associated with guidelines of better quality, and more credible and transparent recommendations. Endorsement of EtD frameworks by guideline developing organizations will likely increase the quality of their guidelines.
