  1. Childsurvival – how many deaths can we prevent and at what cost?

  2. Child mortality and aspects to be covered • An evidence based approach to reducing under-5 deaths. • Estimation of costs • Actual experiences Worldwide around 10 million children under 5 years of age are dying each year

  3. Mortality by cause Interventions Model Resources Impact on mortality A model for linking interventions to Impact on under-5 mortality

  4. Mortality by cause Interventions Model Resources Impact on mortality A model for linking interventions to Impact on under-5 mortality

  5. 24 countries in which over 90% of under-5 deaths occur Neonatal division Asphyxia - 29% Sepsis - 25% Tetanus - 7% Prematurity - 24% (Other is 15%)

  6. Mortality by cause Interventions Model Resources Impact on mortality A model for linking interventions to Impact on under-5 mortality

  7. Intervention selection Central criterion for selection of any intervention is feasibility for delivery at high levels of population coverage in low-income countries. Each potential intervention assigned to one of three levels based on the strength of evidence for its effect on child mortality. 1 – sufficient evidence of effect 2 – limited evidence of effect 3 – Inadequate evidence of effect

  8. Die Interventions by cause - diarrhoea Prevention Treatment Breastfeeding Exposure to diarrhoea Water/San/Hygiene Complementary feeding Oral rehydration therapy Zinc Vitamin A Diarrhoea Antibiotics for dysentry Zinc Survive Future: rotavirus vaccine

  9. Die Interventions, neonatal - prematurity Prevention Treatment Antibiotics for premature rupture of membrane Pregnant Insecticide-treated materials* Intermittent preventive therapy Antinatal steroids Premature Newborn temperature management Survive * Indoor residual spraying may be used as an alternative

  11. Lancet model – calculation types • For each of the 24 countries in sub-Saharan Africa, the number of under-5 deaths that could be prevented was calculated with coverage levels around the year 2000 increased to 99% except for exclusive breastfeeding, where 90% was used. The calculations divided into three types: • Exclusive and continuing breastfeeding, as this involved three levels: exclusive, partial and no breastfeeding • Complementary feeding, which utilized the underweight distribution of under-5s within a country • All other interventions.

  12. Lancet model – calculation of deaths averted For the majority of calculations the proportionate reduction of deaths when intervention coverage is increased from the current value (pc) to target (pt) is = AfEf(pt - pc)/(1 – pcEf) where Ef is the efficacy of the interventionand Af is the fraction of deaths affected by the intervention.

  13. Lancet model – parameters

  15. Lancet model – results by intervention type • Results are calculated on the basis of the situation in the year 2000. • Under-5 deaths preventable through the universal application of the level 1 and 2 interventions were of three types – deaths preventable by: • individual intervention • specific cause • group of interventions

  17. Costing the reduction of under-5 deaths • Costs are difficult to assess: • Commission on Macro-economics and Health estimated US$7.5 billion, but not specifically for child mortality reduction • Single disease estimates, such as HIV/AIDS, malaria and measles have been made, but little use for reduction of child mortality However, with publication of cause-of-death estimates and Lancet model on child deaths that could be averted through use of a package of effective interventions, more can be done on costing the achievement of the MDG on child survival

Lancet June 2005 Individual country costs and situations differ widely

  22. Costing assumptions Average cost per death averted about $890, with neonatal death averted at around $780. But 2005 Lancet neonatal series estimated death averted cost of $2100 (over half of this due to provision of emergency obstetric care). Estimates did not include capital, hiring, training and other infrastructure development costs. Consumer costs were not included. Vaccines and drug cost estimates do not account for expected cost reduction as demand increases However, resources linked to appropriate intervention packages are critical if money is to be effectively used to reduce child mortality

  23. Experiences in Africa

  24. IMCI early implementation phase IMCI expansion phase IMCI household and community component in at least 3 districts (18 countries) IMCI in the Eastern and Southern Africa Region 18 countries in Eastern and Southern Africa Region implement the household and community component of the IMCI strategy The common element:promotion of the key family care practices

  25. The Review2004-2005 • ESAR country experiences with implementing IMCI household and community-based activities (focusing on four countries--Malawi, South Africa, Tanzania, Uganda) • Scientific evidence for the importance of family care practices for a child’s survival, health, and development • Survey evidence on changes in family care practices in four focus countries

  26. Context

  27. By intervention Interventions that have the most direct impact on the child—and could make the most difference… Prevention

  28. Treatment

  29. Percent of total deaths preventable by groups of location associated interventions By location of intervention Health facility outreach includes: zinc, hib vaccine, vitA, tetanus toxoid, nivirapine, clean delivery, measles, IPT and antimalarials Home care includes: breastfeeding, complementary feeding, ITM, WASH and ORT Partial coverage 60% malaria interventions (Abuja target) 70% excl. breastfeeding and all others

  30. Findings

  31. Breastfeeding Children exclusively breastfed up to age 6 months in five ESAR sites (baseline and follow-up) Improving breastfeeding practices could prevent the deaths of 233,000 children in ESAR.

  32. Interventions can improve multiple practices

  33. Three intervention packages Immunization “plus” (EPI + ITNs, deworming & vitamin A) ANC+ (Care for mother,TT, IPTp) IMCI+ (Improved management of pneumonia, malaria and diarrhea, and key family practices) Accelerated child survival and development (ACSD) in West Africa • 11 countries in West Africa • Support from CIDA and other partners • Aim: To reduce mortality among children less than 5 years of age • Strategy: Accelerate coverage with three packages of high-impact interventions, with a special focus on community-based delivery

  34. Three intervention packages Immunization “plus” (EPI + ITNs, deworming & vitamin A) ANC+ (Care for mother,TT, IPTp) IMCI+ (Improved management of pneumonia, malaria and diarrhea, and key family practices) Three intervention packages • Routine EPI+ • Strengthening routine EPI • Vitamin A supplementation • IMCI+ • Family practices promotion • Exclusive breastfeeding • ORT • ITNs (pregnant and under-5s) • Community management of malaria and ARI • Antenatal care+ (ANC+): • Refocused ANC4 • Tetanus immunization • Intermittent presumptive treatment (IPT) against malaria • Vitamin A (post partum) Concept and aim: three packages covering three service delivery modes, plus strengthening local accountabilities through performance contracts and participatory monitoring Started with limited package: EPI+ & ANC+ & ITNs

  35. Three intervention packages Immunization “plus” (EPI + ITNs, deworming & vitamin A) ANC+ (Care for mother,TT, IPTp) IMCI+ (Improved management of pneumonia, malaria and diarrhea, and key family practices) Districts • 16 “high impact”* (population ≈ 3million) • 31 “expansion” (population ≈ 14 million) *now 18 districts, because the Upper East Region of Ghana has been reorganized and now includes 8 rather than 6 districts. ACSD geographic coverage • Countries • 4“high impact” Benin, Ghana, Mali, Senegal • 7 “expansion”

  36. Three intervention packages Immunization “plus” (EPI + ITNs, deworming & vitamin A) ANC+ (Care for mother,TT, IPTp) IMCI+ (Improved management of pneumonia, malaria and diarrhea, and key family practices) Evaluation questions Impact Were there changes in nutrition and mortality in the ACSD “high-impact” districts? Were these changes greater than in the comparison area? Attribution Is it plausible to attribute the impact found to ACSD? Coverage • Were there changes in the ACSD “high-impact” districts? • Were these changes greater than in the comparison area?

  37. Three intervention packages Immunization “plus” (EPI + ITNs, deworming & vitamin A) ANC+ (Care for mother,TT, IPTp) IMCI+ (Improved management of pneumonia, malaria and diarrhea, and key family practices) Evaluation design • Intervention areas • ACSD “high impact” countries/districts (Benin, Ghana, Mali, Senegal) • Comparison areas • All other districts in the country, excluding major metropolitan areas

  39. Three intervention packages Immunization “plus” (EPI + ITNs, deworming & vitamin A) ANC+ (Care for mother,TT, IPTp) IMCI+ (Improved management of pneumonia, malaria and diarrhea, and key family practices) ACSD Implementation • EPI+ • Immunizations and vitamin A supplementation implemented first and most strongly in all four countries • ITNs started strong, but stockouts at UNICEF-Copenhagen limited provision of new nets for >1 year at crucial time • IMCI+ • Facility component received little support • Community component started only in mid to late 2003 • Many messages, some unlikely to affect child mortality • Community tx of pneumonia not included at scale • ACTs not available at community level in any of the three countries • Interventions to address undernutrition given low priority • ANC+ • ACSD inputs focused on IPTp with SP and postnatal vitamin A

  40. Three intervention packages Immunization “plus” (EPI + ITNs, deworming & vitamin A) ANC+ (Care for mother,TT, IPTp) IMCI+ (Improved management of pneumonia, malaria and diarrhea, and key family practices) Key Coverage for EPI+ interventionsbefore and after ACSD, in HIDs Before ACSD After ACSD Benin Ghana Mali Increases in coverage across the board in Ghana and Mali; Benin achieved increases for vitamin A and ITNs.

  41. Three intervention packages Immunization “plus” (EPI + ITNs, deworming & vitamin A) ANC+ (Care for mother,TT, IPTp) IMCI+ (Improved management of pneumonia, malaria and diarrhea, and key family practices) Key Coverage for IMCI+ interventionsbefore and after ACSD, in HIDs Before ACSD After ACSD Benin Ghana Mali No coverage gains, and some significant losses, in sick child care. Exclusive breastfeeding increased in Ghana, declined in Mali.
