Protocol 2.3: Adhere To Parameters For Analysis

All analysis should adhere to the following key parameters (Box 86):

  • Preference of GAM based on WHZ: GAM based on MUAC may only be used in the absence of GAM based on WHZ. In exceptional cases where GAM based on MUAC portrays a much more severe situation than GAM based on WHZ (i.e. two or more phases higher), GAM based on MUAC should also be taken into account along with a critical analysis of the contributing factors before a final phase is determined.
  • GAM based on MUAC classification is based on an analysis of the relationship between WHZ and MUAC in the analysis area and convergence of evidence: GAM based on MUAC must only be used in the absence of GAM based on WHZ, and always using convergence of evidence with contributing factors to arrive at the final phase. In exceptional conditions where GAM based on MUAC portrays a much more severe situation than GAM based on WHZ (i.e. two or more phases), GAM based on MUAC should also be taken into account in the phase classification. MUAC-based classifications should be supported by the relationship between GAM based on WHZ, and GAM based on MUAC in the area of analysis. Convergence of evidence should focus on assessing the status of contributing factors (e.g. disease outbreak, food security crisis) as well as historical trends.
  • Total number of children acutely malnourished and in need of treatment: Technical Working Groups should employ the standard method13 used at the country level by the Country Nutrition Clusters/Sectors when calculating the total number of children in need of treatment to report in the IPC. In addition, where data are available, country Technical Working Groups should work with the Country Nutrition Clusters/Sectors to assess the added value of presenting the total number of children in need of treatment by taking into account all forms of acute malnutrition – i.e. low WHZ (WHZ<-2), presence of oedema, as well as low MUAC (<125 mm).
  • A snapshot in time: The classification provides an overview of the acute malnutrition situation at a specific time period that is either currently occurring or projected within a specified timeframe. Classification is a real-time statement and has a validity period during which the situation is not expected to change. Time validity of the classification can refer to short or long periods depending on the stability of the situation and the needs of decision-makers; it may cover a period of a few weeks or up to a year. If the situation changes during the validity period of the analysis, an update or a new analysis may be required.
  • Frequency: Classification should be conducted whenever there is a need to verify the acute malnutrition
    situation and should be updated frequently in rapidly changing situations.
  • Current classification-specific considerations:
    • Classification is based on actual conditions, regardless of causes, duration and mitigating factors. Hence, classification is guided by actual outcome as measured.
  • Projection-specific considerations:
    • Classification is based on assumptions about factors most likely to influence the evolution of
      acute malnutrition
      .
      Hence, projections should initiate from a good understanding of current and
      historical conditions, and be forecasted based on a set of clear assumptions on the evolution of the
      condition, which may be impacted by past and future shocks.
    • Projections are based on the most likely scenario in the absence of large scale-up response activities.
