Pro-equity immunization and health systems strengthening strategies in select Gavi-supported countries.

BACKGROUND: Achieving universal immunization coverage and reaching every child with life-saving vaccines will require the implementation of pro-equity immunization strategies, especially in poorer countries. Gavi-supported countries continue to implement and report strategies that aim to address implementation challenges and improve equity. This paper summarizes the first mapping of these strategies from country reports. METHODS: Thirteen Gavi-supported countries were purposively selected with emphasis on Gavi's priority countries. Following a scoping of different documents submitted to Gavi by countries, 47 Gavi Joint Appraisals (JAs) for the period 2016-2019 from the 13 selected countries were included in the mapping. We used a consolidated framework synthesized from 16 different equity and health systems frameworks, which incorporated UNICEF's coverage and equity assessment approach - an adaptation of the Tanahashi model. Using search terms, the mapping was conducted using a combination of manual search and the MAXQDA qualitative analysis tool. Pro-equity strategies meeting the inclusion criteria were identified and compiled in an Excel database, and then populated on a tableau visualization dashboard. RESULTS: In total, 258 pro-equity strategies were implemented by the 13 sampled Gavi-supported countries between 2016 and 2019. The framework determinants of social norms, utilization, and management and coordination accounted for more than three-quarters of all pro-equity strategies implemented in these countries. The median number of strategies reported per country was 17. Afghanistan, Nigeria, and Uganda reported the highest number of strategies that we considered as pro-equity. CONCLUSION: Findings from this mapping can be useful in addressing equity gaps, reaching partially immunized, and 'zero-dose' vaccinated children, and valuable resource for countries planning to implement pro-equity strategies, especially as immunization stakeholders reimagine immunization delivery in light of COVID-19, and as Gavi finalizes its fifth organizational strategy. Future efforts should seek to identify pro-equity strategies being implemented across additional countries, and to assess the extent to which these strategies have improved immunization coverage and equity.

Health and immunisation services for the urban poor in selected countries of Asia.

BACKGROUND: Asia is a region that is rapidly urbanising. While overall urban health is above rural health standards, there are also pockets of deep health and social disadvantage within urban slum and peri-urban areas that represent increased public health risk. With a focus on vaccine preventable disease and immunisation coverage, this commentary describes and analyses strengths and weaknesses of existing urban health and immunisation strategy, with a view to recommending strategic directions for improving access to immunisation and related maternal and child health services in urban areas across the region. The themes discussed in this commentary are based on the findings of country case studies published by the United Nations Childrens Fund (UNICEF)  on the topic of immunisation and related health services for the urban poor in Cambodia, Indonesia, Mongolia, Myanmar, the Philippines, and Vietnam. MAIN BODY: Although overall urban coverage is higher than rural coverage in selected countries of Asia, there are also wide disparities in coverage between socio economic groups within urban areas. Consistent with these coverage gaps, there is emerging evidence of outbreaks of vaccine preventable diseases in urban areas. In response to this elevated public health risk, there have been some promising innovations in operational strategy in urban settings, although most of these initiatives are project related and externally funded. Critical issues for attention for urban health services access include reaching consensus on accountability for management and resourcing of the strategy, and inclusion of an urban poor approach within the planning and budgeting procedures of Ministries of Health and local governments. Advancement of local partnership and community engagement strategies to inform operational approaches for socially marginalised populations are also urgently required. Such developments will be reliant on development of municipal models of primary health care that have clear delegations of authority, adequate resources and institutional capabilities to implement. CONCLUSIONS: The development of urban health systems and immunisation strategy is required regionally and nationally, to respond to rapid demographic change, social transition, and increased epidemiological risk.

District team problem solving as an approach to district health programme planning: a review, and survey of its status in selected districts in Indonesia.

District team problem solving (DTPS) was developed by WHO in the 1980s to explicitly engage local stakeholders in decentralized planning and, in later iterations, budgeting of health services. It became WHO's global flagship approach to district-level health priority-setting and planning. DTPS entails multisectoral stakeholders (the team) using local data to prioritize and fund services, and should enhance capacity in management of decentralized healthcare. From the late 1990s, DTPS evolved through several phases in Indonesia. Multiple donors supported its use for planning maternal and child health (MCH) services, with substantive national government input, despite no formal assessment of its sustained uptake or benefits. In the context of new interest to promote DTPS for MCH in Indonesia, we assessed its status there in 2013-14, focussing on its implementation status and on associated MCH data collection (PWS-KIA). We used mixed methods to capture local challenges to and opportunities for DTPS in seven sub-national locations in 6 of Indonesia's 31 provinces. DTPS remained active only in the two locations whose local government ever allocated funds to the process; in the others, it stopped once the initial non-government funding ceased. An official decree establishing DTPS and team membership was only issued in four locations, and it was not evident that the intended multisectoral representation was achieved in any site. Trained DTPS facilitators remained available in only four locations. In all districts, interviewees described PWS-KIA as potentially serving a revived DTPS, but insufficiently robust to underwrite local advocacy for investment in MCH. Although efforts to introduce DTPS as a uniform approach to district MCH planning in Indonesia have not been sustained, strong commitment to evidence-based planning remains. Decentralized health planning processes require quality data, local government buy-in and associated funding, and should link explicitly to broader administrative planning processes and budget cycles.

Economic evaluation of a Child Health Days strategy to deliver multiple maternal and child health interventions in Somalia.

INTRODUCTION: Child Health Days (CHDs) are increasingly used by countries to periodically deliver multiple maternal and child health interventions as time-limited events, particularly to populations not reached by routine health services. In countries with a weak health infrastructure, this strategy could be used to reach many underserved populations with an integrated package of services. In this study, we estimate the incremental costs, impact, cost-effectiveness, and return on investment of 2 rounds of CHDs that were conducted in Somalia in 2009 and 2010. METHODS: We use program costs and population estimates reported by the World Health Organization and United Nations Children's Fund to estimate the average cost per beneficiary for each of 9 interventions delivered during 2 rounds of CHDs implemented during the periods of December 2008 to May 2009 and August 2009 to April 2010. Because unstable areas were unreachable, we calculated costs for targeted and accessible beneficiaries. We model the impact of the CHDs on child mortality using the Lives Saved Tool, convert these estimates of mortality reduction to life years saved, and derive the cost-effectiveness ratio and the return on investment. RESULTS: The estimated average incremental cost per intervention for each targeted beneficiary was $0.63, with the cost increasing to $0.77 per accessible beneficiary. The CHDs were estimated to save the lives of at least 10,000, or 500,000 life years for both rounds combined. The CHDs were cost-effective at $34.00/life year saved. For every $1 million invested in the strategy, an estimated 615 children's lives, or 29,500 life years, were saved. If the pentavalent vaccine had been delivered during the CHDs instead of diphtheria-pertussis-tetanus vaccine, an additional 5000 children's lives could have been saved. CONCLUSIONS: Despite high operational costs, CHDs are a very cost-effective service delivery strategy for addressing the leading causes of child mortality in a conflict setting like Somalia and compare favorably with other interventions rated as health sector "best buys" in sub-Saharan Africa.

Should outbreak response immunization be recommended for measles outbreaks in middle- and low-income countries? An update.

BACKGROUND: Measles caused mortality in >164,000 children in 2008, with most deaths occurring during outbreaks. Nonetheless, the impact and desirability of conducting measles outbreak response immunization (ORI) in middle- and low-income countries has been controversial. World Health Organization guidelines published in 1999 recommended against ORI in such settings, although recently these guidelines have been reversed for countries with measles mortality reduction goals. METHODS: We searched literature published during 1995-2009 for papers reporting on measles outbreaks. Papers identified were reviewed by 2 reviewers to select those that mentioned ORI. World Bank classification of country income was used to identify reports of outbreaks in middle- and low-income countries. RESULTS: We identified a total of 485 articles, of which 461 (95%) were available. Thirty-eight of these papers reported on a total of 38 outbreaks in which ORI was used. ORI had a clear impact in 16 (42%) of these outbreaks. In the remaining outbreaks, we were unable to independently assess the impact of ORI. CONCLUSIONS: These findings generally support ORI in middle- and low-income countries. However, the decision to conduct ORI and the nature and extent of the vaccination response need to be made on a case-by-case basis.

Economic evaluation of measles catch-up and follow-up campaigns in Afghanistan in 2002 and 2003.

This paper assesses the cost-effectiveness of, and the return on the investment in, the 2002 catch-up and the 2003 follow-up measles campaigns in Afghanistan from the perspective of the donor. The catch-up campaign targeted nearly 12 million children aged between six months and 12 years, while the follow-up campaign targeted over five million children aged between 9 and 59 months. Both campaigns successfully vaccinated approximately 96 per cent of the respective target populations, and are expected to avert an estimated 301,000 measles deaths over the next 10 years. The average cost per dose of measles vaccine delivered was USD 0.40. The cost per death prevented is USD 23.6, assuming a case fatality rate of 10 per cent and a discount rate of three per cent. With more than 42,000 measles deaths avoided for every one million US dollars spent, the campaigns are an excellent public health investment for precluding childhood mortality in a country affected by a complex emergency.
