LiST ANALYSIS PROJECT: Interventions to reduce mortality due to malaria

Question:

The purpose of analysis was to estimate the impact of scaling up a package of interventions on U5 and maternal malaria deaths averted in two scale-up scenarios – conservative and according to Roll Back Malaria target

Countries of interest: 52 malaria endemic countries

Version used: Spectrum 4.34 Beta 3

Packages/Interventions of interest:

Direct impact on post neonatal deaths due to malaria:

  • Insecticide treated materials or indoor residual spraying - % of households with at least 1 insecticide treated net or covered by indoor residual spraying
  • Antimalarials – proportion of children 0-59 months with a fever receiving any appropriate antimalarial

Indirect impact on post neonatal deaths due to malaria:

  • Pregnant women protected via IPT or sleeping under an ITN - % pregnant women living in malaria endemic areas and receiving intermittent preventive treatment for malaria (2 doses of sulfadoxine-pryemthamine)
  • IPTP affect the risk for Intrauterine growth restriction, which impacts the risk for stunting, which impacts post neonatal deaths due to malaria

Direct impact on maternal deaths due to malaria:

  • Case management of malaria for pregnant women - % of pregnant women with malaria who are treated
  • Pregnant women protected via IPT or sleeping under an ITN

Target values:

Time frame: Base year of coverage 2008, Target year of coverage 2015

Target scale-up values for interventions for conservative scale up scenario:

Interventions / Proxy interventions to determine coverage change / Annual rate of coverage increase (%)
ITNs / Measles vaccine / 1.2
Antimalarials / ORS / 1.3
IPTp / Antenatal care / 0.4
Case mgt / Antenatal care / 0.4
  • Measles vaccine coverage was used as a proxy for ITNs, since in many countries bed nets are distributed during measles vaccine campaigns
  • % of under 5 with diarrhea given ORS sachets can be used as a proxy for antimalarials, since that is another treatment intervention for children that has good data
  • Antenatal care coverage for pregnant women (4+ visits) was used as a proxy for IPTp and case management of malaria for pregnant women, since those women can receive the IPT treatment when they go for their ANC visit.

Target scale-up values for interventions for scale up scenario according toRoll Back Malaria target:

Interventions / Target year 2015 coverage (%)
ITNs / 95
Antimalarials / 95
IPTp / 95
Case mgt / 95

Outputs of Interest:

Malaria deaths in children under 5 (Yearly and total)

Malaria deaths averted in children under 5 (Yearly and total) = (Malaria deaths in children U5 in no scale up scenario - Malaria deaths in children U5 in scale up scenario)

Under 5 malaria deaths averted by each scaled up intervention (Yearly and total)

Maternal malaria deaths (Yearly and total)

Maternal malaria deaths averted (Yearly and total) = (Maternal malaria deaths in no scale up scenario – Maternal malaria deaths in scale up scenario)

Maternal malaria deaths averted by each scaled up intervention (Yearly and total)

Results:

From year 2008 – 2015, a total of more than 2,600,000 children under 5 deaths and 11,000 maternal deaths were averted due to the scale up of coverage of ITNs, Antimalarials, IPTp, and case management of malaria to 95% (RBM target). Similarly, from year 2008-2015, a total of more than 470,000children under 5 deaths and 632 maternal deaths were averted due to the scale up of coverage of the same package of interventions to their respective conservative values as shown in the above table.
