Strength of recommendations in WHO guidelines using GRADE was associated with uptake in national policy

Abstract

ObjectivesThis study assesses the extent to which the strength of a recommendation in a World Health Organization (WHO) guideline affects uptake of the recommendation in national guidelines. Study Design and SettingThe uptake of recommendations included in HIV and TB guidelines issued by WHO from 2009 to 2013 was assessed across guidelines from 20 low-and middle-income countries in Africa and Southeast Asia. Associations between characteristics of recommendations (strength, quality of the evidence, type) and uptake were assessed using logistic regression. ResultsEight WHO guidelines consisting of 109 strong recommendations and 49 conditional recommendations were included, and uptake assessed across 44 national guidelines (1,255 recommendations) from 20 countries. Uptake of WHO recommendations in national guidelines was 82% for strong recommendations and 61% for conditional recommendations. The odds of uptake comparing strong recommendations and conditional recommendations was 1.9 (95% confidence interval: 1.4, 2.7), after adjustment for quality of evidence. Higher levels of evidence quality were associated with greater uptake, independent of recommendation strength. ConclusionGuideline developers should be confident that conditional recommendations are frequently adopted. The fact that strong recommendations are more frequently adopted than conditional recommendations underscores the importance of ensuring that such recommendations are justified. Key findingsUptake of World Health Organization recommendations in national guidelines is high and associated with strength of recommendation and evidence quality. A higher level of evidence quality was associated with greater uptake of the recommendation, independent of strength. What this adds to what was known?Conditional recommendations are frequently adopted, although less frequently than strong recommendations. What is the implication and what should change now?Guideline developers should be confident that conditional recommendations are frequently adopted. The fact that strong recommendations are more frequently adopted than conditional recommendations underscores the importance of ensuring that such recommendations are justified.

World Health Organization treatment guidelines for drug-resistant tuberculosis, 2016 update

“…As a result, the certainty in the estimates of effects for all the recommendations was qualified as “very low”. Both the strength of a recommendation and the certainty in the evidence upon which the recommendation is based tend to influence the degree to which it is adopted [59]. This underscores the need for more RCTs and for observational series which are better designed and reported, in an effort to limit the confounding and other biases that have characterised many studies of MDR-TB treatment outcomes [41].…”

Outcomes in systematic reviews of complex interventions never reached “high” GRADE ratings when compared with those of simple interventions

“…The weak recommendations resulting from this narrow focus in evidence synthesis and assessment of complex social interventions may further discourage important decisions regarding these interventions, as weak recommendations are less frequently taken up by national guidelines [87].…”

Report on the International Society for Laboratory Hematology Survey on guidelines to support clinical hematology laboratory practice

“…One of the challenges that our community faces is the need for high quality studies on diagnostic accuracy of relevant tests that provide the needed, rigorous evidence to guide practice. As practice guidelines that follow an evidence‐based development processes show greater applicability and use in practice , there is a need to encourage guideline development that follows best guideline development practices and the publication of guideline documents that exemplify best practices.…”
