Improving access to child health services at the community level in Zambia: a country case study on progress in child survival, 2000-2013.

Reductions in under-five mortality in Africa have not been sufficient to meet the Millennium Development Goal #4 (MDG#4) of reducing under-five mortality by two-thirds by 2015. Nevertheless, 12 African countries have met MDG#4. We undertook a four country study to examine barriers and facilitators of child survival prior to 2015, seeking to better understand variability in success across countries. The current analysis presents indicator, national document, and qualitative data from key informants and community women describing the factors that have enabled Zambia to successfully reduce under-five mortality over the last 15 years and achieve MDG#4. Results identified a Zambian national commitment to ongoing reform of national health strategic plans and efforts to ensure universal access to effective maternal, neonatal and child health (MNCH) interventions, creating an environment that has promoted child health. Zambia has also focused on bringing health services as close to the family as possible through specific community health strategies. This includes actively involving community health workers to provide health education, basic MNCH services, and linking women to health facilities, while supplementing community and health facility work with twice-yearly Child Health Weeks. External partners have contributed greatly to Zambia's MNCH services, and their relationships with the government are generally positive. As government funding increases to sustain MNCH services, national health strategies/plans are being used to specify how partners can fill gaps in resources. Zambia's continuing MNCH challenges include basic transportation, access-to-care, workforce shortages, and financing limitations. We highlight policies, programs, and implementation that facilitated reductions in under-five mortality in Zambia. These findings may inform how other countries in the African Region can increase progress in child survival in the post-MDG period.

Costs of introducing pneumococcal, rotavirus and a second dose of measles vaccine into the Zambian immunisation programme: Are expansions sustainable?

BACKGROUND: Introduction of new vaccines in low- and lower middle-income countries has accelerated since Gavi, the Vaccine Alliance was established in 2000. This study sought to (i) estimate the costs of introducing pneumococcal conjugate vaccine, rotavirus vaccine and a second dose of measles vaccine in Zambia; and (ii) assess affordability of the new vaccines in relation to Gavi's co-financing and eligibility policies. METHODS: Data on 'one-time' costs of cold storage expansions, training and social mobilisation were collected from the government and development partners. A detailed economic cost study of routine immunisation based on a representative sample of 51 health facilities provided information on labour and vaccine transport costs. Gavi co-financing payments and immunisation programme costs were projected until 2022 when Zambia is expected to transition from Gavi support. The ability of Zambia to self-finance both new and traditional vaccines was assessed by comparing these with projected government health expenditures. RESULTS: 'One-time' costs of introducing the three vaccines amounted to US$ 0.28 per capita. The new vaccines increased annual immunisation programme costs by 38%, resulting in economic cost per fully immunised child of US$ 102. Co-financing payments on average increased by 10% during 2008-2017, but must increase 49% annually between 2017 and 2022. In 2014, the government spent approximately 6% of its health expenditures on immunisation. Assuming no real budget increases, immunisation would account for around 10% in 2022. Vaccines represented 1% of government, non-personnel expenditures for health in 2014, and would be 6% in 2022, assuming no real budget increases. CONCLUSION: While the introduction of new vaccines is justified by expected positive health impacts, long-term affordability will be challenging in light of the current economic climate in Zambia. The government needs to both allocate more resources to the health sector and seek efficiency gains within service provision.

A Cluster Randomised Trial on the Impact of Integrating Early Infant HIV Diagnosis with the Expanded Programme on Immunization on Immunization and HIV Testing Rates in Rural Health Facilities in Southern Zambia.

BACKGROUND: We assessed the integration of early infant HIV diagnosis with the expanded programme for immunization in a rural Zambian setting with the aim of determining whether infant and postpartum maternal HIV testing rates would increase without harming immunization uptake. METHODS: In an unblinded, location stratified, cluster randomised controlled trial, 60 facilities in Zambia's Southern Province were equally allocated to a control group, Simple Intervention group that received a sensitization meeting and the resupply of HIV testing commodities in the event of a stock-out, and a Comprehensive Intervention group that received the Simple Intervention as well as on-site operational support to facilitate the integration of HIV testing services with EPI. FINDINGS: The average change in number of first dose diphtheria, pertussis, and tetanus vaccine (DPT1) provided per month, per facility was approximately 0.86 doses higher [90% confidence interval (CI) -1.40, 3.12] in Comprehensive Intervention facilities compared to the combined average change in the Simple Intervention and control facilities. The interventions resulted in a 16.6% [90% CI: -7%, 46%, P-value = 0.26] and 10% [90% CI: -10%, 36%, P-value = 0.43] greater change in average monthly infant DBS testing compared to control for the Simple and Comprehensive facilities respectively. We also found 15.76 (90% CI: 7.12, 24.41, P-value < 0.01) and 10.93 (90% CI: 1.52, 20.33, P-value = 0.06) additional total maternal re-tests over baseline for the Simple and Comprehensive Facilities respectively. CONCLUSIONS: This study provides strong evidence to support Zambia's policy of integration of HIV testing and EPI services. Actions in line with the interventions, including HIV testing material supply reinforcement, can increase HIV testing rates without harming immunization uptake. In response, Zambia's Ministry of Health issued a memo to remind health facilities to provide HIV testing at under-five clinics and to include under-five HIV testing as part of district performance assessments.
