2. The Rationale Need of guidance on:
Evidence-based nutrition policy making
Best practices for implementation
Programme experiences repository
Where it is implementing – lessons learned
Cost-effective nutrition interventions
They want/need to know NOW
"More research is needed" is not helpful
3. WHO NUTRITION GUIDELINESDifferent formats, Different locations
4. How do you know which WHO Guideline is current?
5. List of Publicationsis an alternative but may not be complete
6. Supplements in peer-reviewed journals:are these WHO guidelines?
7. WHO RECOMMENDATIONS PROCESS CRITICIZED IN 2007WHO guidelines are insufficiently transparent and not evidence based
Lack of use of systematic reviews
Lack of transparency about judgements
Too much dependence on expert opinion
Lack of emphasis on adapting global guidelines to end users' needs
Tension between time taken and when advice needed
Lack of resources The GRC was only established recently, and it was in response to a problem identified in 2007 by Oxman in Lancet
Conducted a review that examined the use of evidence in recommendations developed by WHO departments.
And found:
WHO guidelines are insufficiently transparent and not evidence based
Lack of use of systematic reviews
Lack of transparency about judgements
Too much dependence on expert opinion
Lack of emphasis on adapting global guidelines to end users' needs
Tension between time taken and when advice needed

8. Solution 2007 - Effective as of 2008 Development of a Guidelines Review Committee
Minimum standards for:
Reporting
Processes
Use of evidence
Revised WHO Handbook for Guideline Development
Different processes for documents to fit different purposes
Rapid advice guidelines
Standard guidelines
Full guidelines A solution was found soon afterwards
A review committee was established – GRC (terms of reference Information Note 16/2007)
Internal and external representation
Meets monthly and reviews proposals for development of guidelines and final guideline products
Minimum standards were set for:
Reporting
Processes
Use of evidence
Revised WHO guidelines for guidelines, 2003 version updated, describes WHO standards and methods for guideline-development process
Different processes for documents to fit different purposes:
Depending on scope and urgency of advice needed
Rapid advice eg- avian influence guideline, response to acute problem
Standard – most frequent case
Full – comprehensive, covering whole disease/policy area
Also: 'Books' – synthesis of recommendations from other sources, not necessarily new treatment recommendations and evidence syntheses but still requiring full referencing
Joint guidelines – sometimes, of WHO with other groups

9. WHO standards for guidelines Principles Initial definition of scope and target audience
Development of 'questions'
Systematic and comprehensive evidence retrieval and synthesis
Development of recommendations based on interpretation of evidence
Management of conflicts of interest
Standards for reporting
Plan for implementation and update
Following principles of guideline development need to be followed
Initial definition of scope and target audience
Development of 'questions' guideline wants to address
Questions: phrase researchable questions using PICO criteria
– Outcomes – not surrogate but patient-important outcomes or public Health outcomes.
- Question important because these are questions that sys review is trying to answer, From elements of your questions, search strategy will be defined,
Systematic and comprehensive evidence retrieval and synthesis
this also includes quality appraisal of the evidence, standard to use GRADE system
Development of recommendations based on interpretation of this evidence
Here also GRADE, provides systematic approach of moving from evidence to recommendations

10. Minimum standards for reporting in WHO guidelines Who was involved and their declaration of interests
How the guideline was developed, including
How the evidence was identified
How the recommendations were made
Use by date (review by date) Minimum requirements, in place in this starting period of GRC and related processes
Valid until end of the year
After that: more stringent criteria according to the WHO guidelines for guidelines
Criteria are:…Minimum requirements, in place in this starting period of GRC and related processes

11. Standards for evidencePrinciples For recommendations:
Synthesis of all available evidence
Evidence summaries for group meetings using standard template
Formal assessment of quality of evidence
Consideration of resource use and costs
Linked evidence to recommendations, explaining reasons for judgements
System for assessing evidence for interventions: GRADE

14. Biological and Behavioural Basis for the Intervention One page "plain English" summary of causal associations and mechanisms by which intervention would be biologically and conceptually plausible in resulting in the expected outcome
By biology experts and/or program planners on the for the intervention
Considers
physiological aspects of the population group(s) being targeted
variety of contexts where this intervention may be particularly beneficial or harmful (i.e. deplete or replete populations; premature infants; etc)
15. Systematic Reviews of Evidence Various levels of evidence on the effects of the intervention for specific outcomes
By nutrition experts together with methodologists, epidemiologists and program experts.
Systematic reviews from the Cochrane Library as well as those published in peer reviewed journals
A specific methodology to assure a standardized approach review of efficacy, effectiveness and safety of interventions in different contexts
Formal consultative process on definition of questions and methods are considered early in the process
