The current guideline will be disseminated through electronic media such as slide presentations, CD-ROMs and the World Wide Web, either through the WHO nutrition and SCN mailing lists or the WHO nutrition web site (59), WHO Global TB Programme web site (79) and the WHO e-Library of Evidence for Nutrition Actions (eLENA) (80). eLENA compiles and displays WHO guidelines related to nutrition, along with complementary documents such as systematic reviews and other evidence that informed the guidelines, biological and behavioural rationales, and additional resources produced by Member States and global partners. In addition, the guideline will be disseminated through a broad network of international partners, including WHO country and regional offices, ministries of health, WHO collaborating centres, universities, other United Nations agencies and nongovernmental organizations involved in TB care and control, and nutritional care and support, respectively. WHO will convene regional and subregional workshops to introduce the final recommendations and to assist national authorities to adopt them. The evidence base in support of the revised principles and recommendations will be published and made available on CD-ROM. Feedback on the principles and recommendations will be documented on these occasions.
Adaptation and implementation
As this is a global guideline, it should be adapted to the context of the Member States. Prior to implementation of these principles and recommendations, a public health programme should have well-defined objectives that take into account available resources, existing policies, suitable delivery platforms and suppliers, communication channels and potential stakeholders. Ideally, these recommendations should be implemented as part of an integrated programme for TB care and support. To ensure that WHO global guidelines and other evidence-informed recommendations for nutrition interventions are better implemented in low- and middle-income countries, the Department of Nutrition for Health and Development works with the WHO EvidenceInformed Policy Network (EVIPNet) programme (81). EVIPNet promotes partnerships at country level between policy-makers, researchers and civil society, to facilitate policy development and implementation through use of the best available evidence.
Monitoring and evaluation of guideline implementation
A plan for monitoring and evaluation, with appropriate indicators, is encouraged at all stages. The impact of this guideline can be evaluated within countries (i.e. monitoring and evaluation of the programmes implemented at national or regional scale) and across countries (i.e. adoption and adaptation of the guideline globally).
For evaluation at the global level, the WHO Department of Nutrition for Health and Development has developed a centralized platform for sharing information on nutrition actions in public health practice implemented around the world. By sharing programmatic details, specific country adaptations and lessons learnt, this platform provides examples of how guidelines are being translated into nutrition actions.
