United States of America: Improving SAM caseload estimates through analysis of incidence factors


BACKGROUND & RATIONALE Child undernutrition is a major contributing factor to child mortality, disease, and disability. High-impact interventions are available to address child undernutrition. Furthermore, effective treatment modalities have been devised to treat children affected by severe acute malnutrition (SAM) with both in-patient and out-patient approaches.


The basis of SAM treatment programming is the estimated number of cases of SAM that will develop during the period of the programme (SAM burden), as that number of anticipated cases guides planning on human, institutional and financial resources required.


The emergency responses to the 2011 nutrition crisis in the Horn of Africa and the 2012 food security and nutrition emergency in the Sahel highlighted inconsistencies in the way SAM burden was calculated and communicated by different countries. In an effort to improve UNICEF’s accuracy and consistency, the UNICEF Nutrition in Emergencies Unit undertook a standardization of the process. Different formulas were reviewed; external experts, senior nutrition advisers and managers in UNICEF, the World Food Programme (WFP) and the World Health Organization (WHO) were consulted; and UNICEF Country offices (COs) participated in webinars to understand the changes and implications for each country. The resulting guidance is the basis for annual SAM supply forecasting. An update in 2014 provided updated guidance on using subnational survey data in SAM burden forecasting with technical input from CDC, and can be found in Annex A of UNICEF’s SAM programming guidance . The current UNICEF SAM programming guidance defines the burden of SAM as the sum of the existing (prevalent) cases and the new (incident) cases. Calculation of these figures relies on prevalence of SAM, population estimates, and an incidence factor for SAM, which are then to be calibrated with programming data if possible.


While the adoption of a global guidance for SAM burden has been helpful to standardize programming, technical limitations the components used for calculation, and therefore overall guidance, remain. The SAM incidence factor of 1.6 was developed based on historical data, however there are indications that there is greater variation between countries and that routine survey, programme and surveillance data may be useful in the generation of country specific SAM incidence factors. The issue is of interest to a wide range of partners, including national governments as well as the range of nutrition actors engaged in this area. For example, Global Nutrition Cluster partners in October 2015 calling for improving SAM burden estimation guidance in a way that takes into account MAM caseload estimate development as well at the Global Nutrition Cluster meeting.


Improving methods for determining SAM incidence factors is the core area of work for the consultancy, recognizing that some of the other limitations to the global guidance- such as the discrepancy between prevalence based on weight-for-height versus MUAC and variation with seasonality- require further work through other processes.


PURPOSE Given UNICEF’s corporate commitment to working with national governments on scaling up SAM management globally, improved tools for country level staff to improve programming is a priority. The overall purpose of the consultancy is to improve methods for generating SAM burden estimates through improved methods


The work to be undertaken through this contract will help inform the update to global guidance for SAM programme planning. Where possible and relevant, the analysis will engage with stakeholders involved in generating global modelled estimates of child malnutrition (eg. WHO, World Bank, UNICEF) and stakeholders engaged in technical discussions on MAM caseload estimates. The work is not however intended to replace these complementary lines of work.


EXPECTED RESULTS: (MEASURABLE RESULTS) The main objective of the research is to understand if, how, and the extent to which SAM incidence factors vary between country contexts in order to improve programme planning tools, specifically caseload estimates. This consultancy will, in particular, address the following questions: • What are the gaps in the distribution and quality of available data for SAM incidence? • Where data exists, to what degree does SAM incidence vary between countries? • Where data exists, to what degree does SAM incidence vary subnationally and seasonally? • What are the minimum capacity and data requirements to generate country-specific SAM incidence? • What are the potential implications of variations in SAM incidence factors on global modelling and joint estimates of SAM burden?


The specific objectives of the assignment are to: • Issue a call for available survey and programme data to conduct analysis of SAM incidence • Provide a stocktake of gaps in available survey and programme data to inform future data collection • Consolidate and clean available country level data relevant to the SAM incidence analysis • Perform country level data analysis of SAM incidence and generate country specific SAM incidence factors, and provide an analysis of the implications of the observed level of variation for SAM programming • Facilitate consultation with technical experts and stakeholders on the application of available methods for calculating country specific SAM incidence • Provide evidence for UNICEF and relevant stakeholders to update SAM caseload estimate guidance
