Assessing coverage of interventions for reproductive, maternal, newborn, child, and adolescent health and nutrition

Progress has been made in priority interventions, but we need new measurement systems that include the whole life course and give better assessment of equity of coverage, argue Jennifer Requejo and colleagues


E
mbedded within the framework of the United Nations sustainable development goals (SDG) for 2030 is the principle of equity, with the aim of reaching universal health coverage.Soon after the framework was adopted in 2015, the Every Woman Every Child global strategy for women's, children's and adolescents' health was launched. 1 2The global strategy translates the SDG agenda into concrete guidance on how to accelerate progress in women's, children's and adolescents' health through a multisectoral approach.It includes a monitoring framework with 60 indicators to help countries and their partners promote accountability in ending preventable deaths (survive), ensuring health and wellbeing (thrive), and expanding enabling environments, so that all women, children, and adolescents can reach their potential (transform). 3Previous assessments show mixed progress, with some indicators advancing more rapidly than others but with pervasive inequities between and within countries. 4he Countdown to 2030 initiative also regularly tracks progress in the countries experiencing the highest burdens of maternal and child mortality.Countdown's 2017 report, 5 together with those from Every Woman Every Child, highlight laudable reductions in maternal and child mortality over the past two decades, but many settings will need to increase efforts to achieve the 2030 goals.Coverage of essential health interventions is unacceptably low in many contexts and among specific populations; considerable policy and programmatic work is needed to shore up primary healthcare systems to make universal health coverage a reality. 5e combine the countdown and global strategy indicators to take stock of progress in all 138 low and middle income countries plus Panama, which was reclassified as a high income country in 2018 but remains a priority country in Countdown to 2030. 6We examine how well the world is doing in reaching every woman, child, and adolescent with effective health interventions, how far we need to go to achieve the SDGs, and identify gaps in the data.We also propose revisions to the Countdown chart of key indicators so that it better reflects the dimensions of survive, thrive, and transform in the Every Woman Every Child strategy and the interconnecting links between reproductive, maternal, newborn, child, and adolescent health and nutrition.
Our assessment is based on the common evaluation framework underlying the countdown and global strategy analyses (see web supplement).This framework posits that health outcomes are determined by the ability of healthcare systems to deliver high quality services to all, which, in turn, depends on supportive policies and sufficient resources, including financial, supplies and equipment, and healthcare workers.The framework also considers contextual factors, such as humanitarian and environmental crises, women's social status, and other political and economic factors that influence access to services, and the independent effects of education and other life opportunities on health.

Understanding gaps and success
Multiple analytical lenses are needed to understand whether women, children, and adolescents worldwide are receiving effective health interventions.Snapshots of current status tell us where we are and how far we need to go to reach global goals.However, it's important to visualise trends to determine whether progress is accelerating, stagnating, or even reversing.Countdown's indicator list helps determine which specific interventions are reaching women, children, and adolescents better than others.Another approach involves ranking countries and regions to identify those that are performing best and those that are lagging behind, providing insight into which countries and regions need constructive action to direct resources and support.

Where are we now?
Countdown's continuum of care chart shows a subset of prioritised indicators of intervention coverage across the dimensions of family planning, pregnancy, childbirth, postnatal care, and childhood, with selected crosscutting indicators for water and sanitation.These indicators reflect population level data, showing how well countries are doing in reaching those in need.Figure 1 shows progress on this chart for all low and middle income countries for 2014-18. 7 8Summary data (table 1) show that we are far from achieving universal coverage for many interventions, with larger gaps for family planning services, breastfeeding, and treatment of childhood

KEY MESSAGES
• Despite substantial progress in reduc- ing maternal, newborn, and child mortality worldwide, inequities persist      The data suggest that immunisation coverage is flatlining.Many countries experience challenges over vaccines costs, vaccine supply chains, and difficulties reaching the most disadvantaged children in remote or rural areas, or in slums.In some countries parental willingness to vaccinate is also a problem.Although considerable attention has been devoted to understanding vaccine hesitancy in high income settings, most unvaccinated children live in areas without reliable access to them. 9urther scrutiny is needed to understand the factors driving positive trends in low and middle income countries as well as those that are inhibiting progress so that appropriate action can be taken.Interventions with high national coverage can start to fall behind as focus shifts elsewhere.Gains need to be sustained through close partnerships between the global community, governments, and local civil society groups.

Best and worst performing countries
Indices including standardised indicators are useful for comparing overall country performance towards specific development goals.Such comparisons can help to identify which countries are progressing and which are falling behind and should trigger additional national and sub-national analyses to understand the factors driving success and failure.
We used the composite coverage index (CCI) 10 to rank countries with available data on every indicator included in the index during 2010-18 (45 countries lack available data, most of which are middle income countries in Europe, North America, Oceania, and Latin America and the Caribbean).The CCI is an established summary measure for intervention coverage that correlates with key indicators of health status such as child mortality and stunting.It is calculated from data provided by UN member states, so the quality of the measure is only as strong as the underlying data.
The index has four components (reproductive health, maternal health, child immunisation, and treatment of childhood illness), is limited to interventions delivered through healthcare systems, and has eight coverage indicators: access to modern family planning methods, four or more antenatal care visits, skilled attendant at birth, three doses of DTP vaccine, BCG vaccination, first dose of measles vaccine, oral rehydration salts for diarrhoea, and care seeking for acute respiratory infections (see web supplement for details on how the index is calculated).
Figure 3 shows a heatmap of the CCI for the five best and five worst performing countries (a heat map for all low and middle income countries is given in the web supplement).Indicators for the best performers are mostly green, but all have slightly lower coverage for treating childhood illness.The indicators for the lowest performers, in contrast, are mostly red and orange, with some performing better for immunisations.A comprehensive on 22 March 2024 by guest.Protected by copyright.http://www.bmj.com/BMJ: first published as 10.1136/bmj.l6915on 26 January 2020.Downloaded from approach is clearly needed for these countries to increase access to care for women and children.
The best performers are spread across different world regions, but apart from Yemen the lowest performers are all in Africa, suggesting that greater attention needs to be directed there.Comparing these countries' performance on the CCI to mortality statistics provides support for the role of this evaluation framework and the role of high intervention coverage in improving survival.The highest performers have all achieved considerable reductions in maternal and child mortality over the past 10 years. 11 12The poorest performers, in contrast, have made less progress in improving maternal and child survival; all but Equatorial Guinea have levels of stunting of at least 30%, and four of the five (Central African Republic, Chad, South Sudan, and Yemen) are affected by conflict or are fragile states . 13 14ere do we go from here?Global monitoring involves regular tracking of sentinel indicators to assess progress towards fixed goals and targets.But global monitoring is also an iterative process, staying on track with changes in the evidence on effective interventions, implementation strategies, demographic and epidemiological trends, and country priorities.Thus, indicators monitored through global initiatives need to be regularly reviewed and updated.
The SDG and Every Woman Every Child strategy frameworks use a life course approach to development, which has been reflected in strategic plans, programming, and research agendas.The large reduction in child mortality 11 has enabled a shift from a focus on reducing deaths from infectious Improvements in maternal mortality from direct causes means that indirect causes such as reduced fertility and women having their first pregnancies at older ages are becoming more important. 12The focus of action is therefore shifting from improving access to intrapartum and emergency obstetric care to include women's experiences of care, the quality of available services, short and long term forms of maternal morbidity and disability, and women's empowerment, social status, and rights.
Available evidence also shows huge variations in countries' progress on the epidemiological, demographic, and nutritional transitions and hence "one size fits all" approaches to development will not work.Poverty reduction is not a straight trajectory, and success can be precarious.Conflict, global recessions, in-country economic crises, environmental disasters, and epidemics can all cause massive destruction, particularly if resilience and safety nets are not built into health and other systems.Several countries were downgraded, for example, in the 2019 World Bank income classifications, with implications for the resources they have for social protection, health, and other welfare programmes. 6Hence, the international community and country governments must remain vigilant and rapidly respond to deteriorating situations as part of the pledge to achieve sustainable development.
The challenge in selecting core indi cators for global monitoring is to keep the number small so that reporting burdens on countries are manageable yet comprehensive enough to be relevant and spur action.We cannot lose sight of the fact that the leading killers of young children stubbornly remain pneumonia, diarrhoea, and malaria (in endemic areas), often underpinned by undernutrition.But the indicator set needs to encompass children aged 5-9 years, along with other emerging priorities relating to chronic diseases, disabilities, injuries, violence, and child development.
Adolescent health has garnered considerable attention in recent years. 15owever, only a few adolescent specific indicators have been included in global monitoring frameworks, mainly around reproductive and maternal health, and most are not included as part of routine data collection activities, which hampers accountability. 16n response to evidence documenting an increasing proportion of child deaths in the neonatal period, numerous initiatives have aimed to improve monitoring around maternal and newborn health, including health systems, community, and broader social, political, and environmental determinants, and the design and implementation of effective programmes. 17 18This has also prompted greater focus on the quality of care provided before, during, and immediately after delivery and motivated the development of guidance on assessing health facility readiness to provide high quality care and health workers' performance. 19he importance of a life course approach has become internationally recognised, as has the salience of viewing women's, children's, and adolescents' health as interlinked and having intergenerational effects.However, data collection efforts are a few steps behind, with data gaps and measurement challenges persisting.Even for those indicators that cover well established interventions, many countries are missing data from the past five years (tables 1 and 2).Most of the 139 countries have modelled data for established interventions such as immunisations, water and sanitation, and HIV.The number of countries with household survey based data range from 61 (for postnatal care for babies) to 109 (for skilled attendant at birth).This wide range in data availability is due to a combination of factors-some of the interventions are new or have never been included in country programmes or data collection processes (eg, rotavirus vaccine, postnatal care for babies) but many of the 139 countries have not conducted a household survey in the past five years.As countries develop and move from low income to middle income status, they often decide to carry out their own national household surveys, which do not always follow standardised methods (such as the international demographic and health surveys).These surveys generate non-comparable data, limiting inclusion in global databases.Conflict or other circumstances can also preclude nationally representative household surveys, and some countries have not provided the resources to carry out surveys.
Global stewardship is now needed on several fronts: • To increase data collection efforts and to generate more comparable data • To increase investments in countries' health information systems and promote better use of existing data • To coordinate existing initiatives on updating core lists of indicators to monitor progress towards the 2030 goals • To refine and move forward the measurement agenda, and • To push for accountability so that every woman, child, and adolescent gets the care they deserve.
Promising efforts are under way to close data gaps for women, children, and adolescents. 16 20WHO and Unicef have engaged experts to reach consensus on how to define and measure effective coverage in order to better capture the potential effect health services can have on health and nutrition outcomes. 21 A consultative process for revising the continuum of care chart should incorporate all these changes on the global landscape, technical advancements in measurement, and country realities.Both the Countdown and Every Woman Every Child indicator lists were derived from lengthy consultative processes involving academia, civil society, UN agencies, healthcare professionals, and countries' ministries of health. 3 5A similar process, soon to be instituted, will allow reporting on key indicators of intervention coverage at the midpoint of the SDG period, enabling assessment of whether global progress is on track.3][24] The process should examine how best to obtain data for missing or under-represented areas such as children aged 5-9, adolescents aged 10-14, adolescent indicators beyond reproductive and maternal health, environmental indicators beyond water and sanitation, and a wider list of reproductive and sexual health indicators as part of health outcomes for adult women.
The revised chart should still be viewed as embedded within the common evaluation framework, serving as a starting point for further analyses focusing on key drivers of coverage such as equity, policy and legislative frameworks, and contextual and health systems factors.A companion chart on quality of care measures is also being developed. 25Unicef and WHO, in partnership with Countdown to 2030, the UN Population Fund (UNFPA), and other UN agencies will lead this consultative process.

Conclusion
Our analyses show that work is needed to achieve universal coverage of important health interventions and to prevent interventions with high coverage levels, such as immunisations, from backsliding.Indicator lists and reporting processes must evolve so that they remain relevant to guide national action and programmatic responses.We have suggested a consultative process for revising Countdown's continuum of care chart to bring it up to date with new thinking on life course approaches and to ensure a manageable set of indicators for reporting on the survive, thrive, and transform dimensions of the Every Woman Every Child strategy.We believe greater investment in data collection is needed so that all countries can report on a core set of indicators, enabling meaningful assessments of global progress.
Finally, further disaggregation of intervention coverage by key markers of equity and the application of newer techniques such as geospatial analyses are essential to improve our understanding of who is being left behind.This information is the starting point for designing strategies to reach all women and children, and for holding all to account for successful implementation.
