A New Template for Standardized Wording when Reporting Evidence-to-Decision Considerations in Guidelines

One of the major tenets of GRADE is that certainty of the evidence is just one component of decision-making. Ultimately, decision-makers also need to take into account important factors such as values and preferences, feasibility, and considerations of the impact of a decision on health equity and resource utilization. These factors and others are part of the Evidence-to-Decision (EtD) framework that guides the process from the assessment of certainty of evidence to the final formulation of recommendations in a structured, transparent manner.

Often, multiple teams and individuals involved in the development of a guideline will need to work together to compete the EtD process, which can be a source of confusion. Additionally, until now, no official guidance existed for the use of standardized wording when considering and reporting each EtD framework component. Earlier this year, Piggott and colleagues aimed to address this issue with an article published in the Journal of Clinical Epidemiology.

The project, comprising ten guideline development groups and over 250 recommendations, set out to develop a standardized framework for clear, transparent, and efficient wording when reporting Evidence-to-Decision components within a guideline. This template was then used in two guidelines in development - the European Commission Initiative on Breast Cancer (ECIBC) and the Endocrine Society guidelines on hyperglycemia, hypoglycemia and hypercalcemia. During this process, the authors were able to pilot the wording, receive feedback, and refine the template. The real-life guidelines were also used to provide examples of wording recommendations.

The article includes suggested wording structure and examples for reporting the magnitude and certainty of effect estimates, for conclusions of each portion of the EtD framework, and for justification of recommendations as well as notes on implementation considerations, monitoring and evaluation, and research priorities. 

The authors note that these suggestions are preliminary and may require further refinement. Additionally, current examples of consistent and clear wording of EtDs continues to be lacking, though the dissemination of this guidance may improve future publications. While the suggestions within the article are focused on clinical decisions related to management of conditions, future efforts may expand this to guidelines for diagnostic testing, coverage, and other important areas.

U.S. GRADE Network Holds Its First Two-Day Systematic Review Workshop

In response to popular demand, the U.S. GRADE Network recently expanded its half-day course on systematic reviews into a two-day virtual workshop. Taking place over February 1-2, 2022, the sessions comprised six total hours of instructional time and question-and-answer sessions with Network faculty in addition to three hours of hands-on activities in a small-group format. Large-group lectures ranged from developing a focused clinical question to conducting meta-analysis and evaluating the quality of systematic reviews. In hands-on sessions of ten participants each, attendees were introduced to a free online screening platform (Rayyan) and tried their hands at assessing risk of bias and conducting meta-analysis in RevMan, a free systematic review and meta-analysis software from Cochrane.

As part of the program, the Evidence Foundation welcomed three recipients of scholarships to attend the workshop free of charge. As part of their applications, the scholars described a current or proposed project for a systematic review. The three recipients, along with their projects, included:
• Bryden Giving, MAOT, OTR/L (Boston University): A traffic light of evidence for occupational therapy interventions supporting autistic children and youth
• Nirjhar Ruth Ghosh, MS (Texas A&M University): Evidence-based practice in the field of nutrition: A systematic review of knowledge, skills, attitudes, behaviors and teaching strategies
• Milton A. Romero-Robles (Universidad Nacional del Santa): Participation, involvement and main barriers in the inclusion of patients with non-communicable diseases in the development of clinical practice guidelines: A systematic review protocol
