Table 4 Impact of replenishment on LLIN programme cost and cost effectiveness

From: Cost and cost effectiveness of long-lasting insecticide-treated bed nets - a model-based analysis

Result Lifespan Scenario 1: S-shaped loss rate Scenario 2: 5% of distributed nets lost p.a. Scenario 3: 10% of remaining nets lost p.a.
Number of replenishment nets required 3 years 717,000 300,00 600,000
  4 years 644,600 350,000 700,000
Total replenishment cost (delivery cost) 3 years USD 4.47 m (USD 906,000) USD 1.87 m (USD 382,000) USD 3.75 m (USD 767,000)
  4 years USD 4.32 m (USD 816,000) USD 2.17 m (USD 443,000) USD 4.34 m (USD 886,000)
Impact of replenishment on programme cost 3 years +26% +11% +22%
  4 years +33% +17% +33%
Impact of replenishment
on programme effect
(under-5 deaths averted)
3 years 2780 more deaths averted (+9.9%) 1386 more deaths averted (+4.7%) 2680 more deaths averted (+9.5%)
  4 years 3087 more deaths averted (+11%) 2002 more deaths averted (+7.0%) 3764 more deaths averted (+14%)
Cost per under-5 death averted with (without) replenishment 3 years USD 701 (611) USD 617 (582) USD 678 (609)
  4 years USD 567 (474) USD 497 (456) USD 568 (486)
Incremental cost effectiveness of replenishment: cost per additional under-5 death averted (per person protected p.a) 3 years USD 1609 (25) USD 1353 (21) USD 1399 (22)
  4 years USD 1400 (22) USD 1085 (17) USD 1154 (18)
