Data analysis methods suited to the NIPN set-up (3/3)

3. Analysis of the cost-effectiveness of interventions requires a research setting

  • Measuring the cost-effectiveness of interventions requires the comparison of different interventions, measuring their relative impact, and measuring very precisely all direct and indirect costs related to the interventions.
  • It typically requires a research setting and a rigorous scientific study design to collect these data.
  • A cost-effectiveness analysis is not suited to the NIPN approach, which does not aim to collect new data, but rather make use of existing data collected in population-based surveys.
Example of a cost-effectiveness study
  • The REFANI Pakistan study – a cluster randomised controlled trial of the effectiveness and cost-effectiveness of cash-based transfer programmes on child nutrition status: study protocol. Fenn B. et al. 2015. BMC Public Health 15(1044).
  • The E-lena library of WHO compiled more than 100 peer reviewed articles and reports assessing the cost-effectiveness of a wide range of nutrition interventions in a variety of contexts and settings.
