Improving antimicrobial use among health workers in first-level facilities: results from the multi-country evaluation of the Integrated Management of Childhood Illness strategy.

OBJECTIVE: The objective of this study was to assess the effect of Integrated Management of Childhood Illness (IMCI) case management training on the use of antimicrobial drugs among health-care workers treating young children at first-level facilities. Antimicrobial drugs are an essential child-survival intervention. Ensuring that children younger than five who need these drugs receive them promptly and correctly can save their lives. Prescribing these drugs only when necessary and ensuring that those who receive them complete the full course can slow the development of antimicrobial resistance. METHODS: Data collected through observation-based surveys in randomly selected first-level health facilities in Brazil, Uganda and the United Republic of Tanzania were statistically analysed. The surveys were carried out as part of the multi-country evaluation of IMCI effectiveness, cost and impact (MCE). FINDINGS: Results from three MCE sites show that children receiving care from health workers trained in IMCI are significantly more likely to receive correct prescriptions for antimicrobial drugs than those receiving care from workers not trained in IMCI. They are also more likely to receive the first dose of the drug before leaving the health facility, to have their caregiver advised how to administer the drug, and to have caregivers who are able to describe correctly how to give the drug at home as they leave the health facility. CONCLUSIONS: IMCI case management training is an effective intervention to improve the rational use of antimicrobial drugs for sick children visiting first-level health facilities in low-income and middle-income countries.

Reducing child mortality: can public health deliver?

This is the third paper in the series on child survival. The second paper in the series, published last week, concluded that in the 42 countries with 90% of child deaths worldwide in 2000, 63% of these deaths could have been prevented through full implementation of a few known and effective interventions. Levels of coverage with these interventions are still unacceptably low in most low-income and middle-income countries. Worse still, coverage for some interventions, such as immunisations and attended delivery, are stagnant or even falling in several of the poorest countries. This paper highlights the importance of separating biological or behavioural interventions from the delivery systems required to put them in place, and the need to tailor delivery strategies to the stage of health-system development. We review recent initiatives in child health and discuss essential aspects of delivery systems, including: need for data at the subnational level to support health planning; regular monitoring of provision and use of health services, and of intervention coverage; and the need to achieve high and equitable coverage with selected interventions. Community-based initiatives can extend the delivery of interventions in areas where health services are hard to access, but strengthening national health systems should be the long-term aim. The millennium development goal for child survival can be achieved, but only if strategies for delivery interventions are greatly improved and scaled-up.

Where and why are 10 million children dying every year?

More than 10 million children die each year, most from preventable causes and almost all in poor countries. Six countries account for 50% of worldwide deaths in children younger than 5 years, and 42 countries for 90%. The causes of death differ substantially from one country to another, highlighting the need to expand understanding of child health epidemiology at a country level rather than in geopolitical regions. Other key issues include the importance of undernutrition as an underlying cause of child deaths associated with infectious diseases, the effects of multiple concurrent illnesses, and recognition that pneumonia and diarrhoea remain the diseases that are most often associated with child deaths. A better understanding of child health epidemiology could contribute to more effective approaches to saving children's lives.

Inequities among the very poor: health care for children in rural southern Tanzania.

BACKGROUND: Few studies have been done to assess socioeconomic inequities in health in African countries. We sought evidence of inequities in health care by sex and socioeconomic status for young children living in a poor rural area of southern Tanzania. METHODS: In a baseline household survey in Tanzania early in the implementation phase of integrated management of childhood illness (IMCI), we included cluster samples of 2006 children younger than 5 years in four rural districts. Questions focused on the extent to which carers' knowledge of illness, care-seeking outside the home, and care in health facilities were consistent with IMCI guidelines and messages. We used principal components analysis to develop a relative index of household socioeconomic status, with weighted scores of information on income sources, education of the household head, and household assets. FINDINGS: 1026 (52%) of 1968 children reported having been ill in the 2 weeks before the survey. Carers of 415 (41%) of 1014 of these children had sought care first from an appropriate provider. 71 (26%) carers from families in the wealthiest quintile knew > or =2 danger signs compared with 48 (20%) of those from the poorest (p=0.03 for linear trend across quintiles) and wealthier families were more likely to bring their sick children to a health facility (p=0.02). Their children were more likely than poorer children to have received antimalarials, and antibiotics for pneumonia (p=0.0001 and 0.0048, respectively). INTERPRETATION: Care-seeking behaviour is worse in poorer than in relatively rich families, even within a rural society that might easily be assumed to be uniformly poor.

Meeting international goals in child survival and HIV/AIDS.

BACKGROUND: After a decade of focused efforts to reduce under-5 mortality results have been mixed, with the HIV/AIDS epidemic often used to explain reversing trends. We investigated this assumption by estimating HIV-attributable under-5 mortality in 39 countries in sub-Saharan Africa and comparing it to total mortality in children younger than 5 years between 1990 and 1999. METHODS: Annual HIV-attributable under-5 mortality was estimated in a four-step process with previously obtained data from antenatal clinics in 39 countries based on HIV sero-prevalence among pregnant women. This process produced estimates of: the number of children born to HIV-infected women; the number of children infected via mother-to-child-transmission of HIV; the number of HIV-infected children who died before age 5 years; and the number of HIV-infected children who died before age 5 years adjusted for competing causes of mortality. FINDINGS: An estimated 330,000 children younger than age 5 years died in sub-Saharan Africa in 1999 with HIV infection. When corrected for competing causes of mortality, HIV infection caused 7.7% of under-5 deaths in 1999, a significant rise from 2% in 1990. Five countries (Botswana, Namibia, Swaziland, Zambia, and Zimbabwe) have rates of HIV-attributable under-5 mortality of above 30 per 1000. An additional 16 countries have HIV-specific under-5 mortality rates between 10 and 25 per 1000. The remaining 18 countries have rates under 10 per 1000. INTERPRETATION: HIV/AIDS is an increasingly important cause of under-5 mortality in Africa. However, in many African countries, slowing or reversal of trends in child mortality cannot be explained by HIV alone. To meet international goals for reductions in child mortality, efforts must continue to focus on HIV/AIDS, but must also strengthen health systems that can deliver available interventions for the other major killer diseases of children in the developing world.

Estimates of world-wide distribution of child deaths from acute respiratory infections.

Acute respiratory infections (ARI) are among the leading causes of childhood mortality. Estimates of the number of children worldwide who die from ARI are needed in setting priorities for health care. To establish a relation between deaths due to ARI and all-cause deaths in children under 5 years we show that the proportion of deaths directly attributable to ARI declines from 23% to 18% and then 15% (95% confidence limits range from +/- 2% to +/- 3%) as under-5 mortality declines from 50 to 20 and then to 10/1000 per year. Much of the variability in estimates of ARI in children is shown to be inherent in the use of verbal autopsies. This analysis suggests that throughout the world 1.9 million (95% CI 1.6-2.2 million) children died from ARI in 2000, 70% of them in Africa and southeast Asia.

Achieving universal coverage with health interventions.

Cost-effective public health interventions are not reaching developing country populations who need them. Programmes to deliver these interventions are too often patchy, low quality, inequitable, and short-lived. We review the challenges of going to scale, building on known, effective interventions to achieve universal coverage. One challenge is to choose interventions consistent with the epidemiological profile of the population. A second is to plan for context-specific delivery mechanisms effective in going to scale, and to avoid uniform approaches. A third is to develop innovative delivery mechanisms that move incrementally along the vertical-to-horizontal axis as health systems gain capacity in service delivery. The availability of sufficient funds is essential, but constraints to reaching universal coverage go well beyond financial issues. Accurate estimates of resource requirements need a full understanding of the factors that limit intervention delivery. Sound decisions need to be made about the choice of delivery mechanisms, the sequence of action, and the pace at which services can be expanded. Strong health systems are required, and the time frames and funding cycles of national and international agencies are often unrealistically short.

Integrated Management of Childhood Illness (IMCI) in Bangladesh: early findings from a cluster-randomised study.

BACKGROUND: We report the preliminary findings from a continuing cluster randomised evaluation of the Integrated Management of Childhood Illness (IMCI) strategy in Bangladesh. METHODS: 20 first-level outpatient facilities in the Matlab sub-district and their catchment areas were randomised to either IMCI or standard care. Surveys were done in households and in health facilities at baseline and were repeated about 2 years after implementation. Data on use of health facilities were recorded. IMCI implementation included health worker training, health systems support, and community level activities guided by formative research. FINDINGS: 94% of health workers in the intervention facilities were trained in IMCI. Health systems supports were generally available, but implementation of the community activities was slow. The mean index of correct treatment for sick children was 54 in IMCI facilities compared with 9 in comparison facilities (range 0-100). Use of the IMCI facilities increased from 0.6 visits per child per year at baseline to 1.9 visits per child per year about 21 months after IMCI introduction. 19% of sick children in the IMCI area were taken to a health worker compared with 9% in the non-IMCI area. INTERPRETATION: 2 years into the assessment, the results show improvements in the quality of care in health facilities, increases in use of facilities, and gains in the proportion of sick children taken to an appropriate health care provider. These findings are being used to strengthen child health care nationwide. They suggest that low levels of use of health facilities could be improved by investing in quality of care and health systems support.

Gaps in policy-relevant information on burden of disease in children: a systematic review.

BACKGROUND: Valid information about cause-specific child mortality and morbidity is an essential foundation for national and international health policy. We undertook a systematic review to investigate the geographical dispersion of and time trends in publication for policy-relevant information about children's health and to assess associations between the availability of reliable data and poverty. METHODS: We identified data available on Jan 1, 2001, and published since 1980, for the major causes of morbidity and mortality in young children. Studies with relevant data were assessed against a set of inclusion criteria to identify those likely to provide unbiased estimates of the burden of childhood disease in the community. FINDINGS: Only 308 information units from more than 17,000 papers identified were regarded as possible unbiased sources for estimates of childhood disease burden. The geographical distribution of these information units revealed a pattern of small well-researched populations surrounded by large areas with little available information. No reliable population-based data were identified from many of the world's poorest countries, which account for about a third of all deaths of children worldwide. The number of new studies diminished over the last 10 years investigated. INTERPRETATION: The number of population-based studies yielding estimates of burden of childhood disease from less developed countries was low. The decreasing trend over time suggests reductions in research investment in this sphere. Data are especially sparse from the world's least developed countries with the highest child mortality. Guidelines are needed for the conduct of burden-of-disease studies together with an international research policy that gives increased emphasis to global equity and coverage so that knowledge can be generated from all regions of the world.

Can the world afford to save the lives of 6 million children each year?

BACKGROUND: In July, 2003, the Bellagio Study Group on Child Survival estimated that the lives of 6 million children could be saved each year if 23 proven interventions were universally available in the 42 countries responsible for 90% of child deaths in 2000. Here we assess the cost of delivering these interventions, and discuss whether the achievement of the Millennium Development Goal (MDG) for child survival falls within the financial capacities of donors and developing countries. METHODS: All child survival interventions shown to reduce mortality from the major causes of death in children younger than 5 years were incorporated into a delivery timetable comprised of 18 contacts between a child or mother and a health-care provider in the period from before birth until the child reaches 5 years. The running costs of delivering the interventions at universal coverage levels were calculated as the sum of unit costs for drugs and materials, delivery costs, and programme management and support costs, including supervision. We estimated the cost of providing interventions at coverage levels reported for 2000 and the additional costs of providing services at universal coverage levels. FINDINGS: USD 5.1 billion in new resources is needed annually to save 6 million child lives in the 42 countries responsible for 90% of child deaths in 2000. This cost represents 1.23 dollars per head in these countries, or an average cost per child life saved of 887 dollars. Sensitivity analyses for salary levels for community delivery agents, drug costs, and coverage rates for 2000 were used to develop uncertainty estimates around the USD 5.1 billion annual price tag that range from about 3.1 billion dollars to 8.0 billion dollars. INTERPRETATION: Achieving the MDG for child survival is affordable for donors and developing countries. Scaling up health delivery is the challenge, and, along with the lack of funds, will be the limiting factor in reducing child mortality by two-thirds by 2015.

Co-coverage of preventive interventions and implications for child-survival strategies: evidence from national surveys.

BACKGROUND: In most low-income countries, several child-survival interventions are being implemented. We assessed how these interventions are clustered at the level of the individual child. METHODS: We analysed data from Bangladesh, Benin, Brazil, Cambodia, Eritrea, Haiti, Malawi, Nepal, and Nicaragua. A co-coverage score was obtained by adding the number of interventions received by each child (including BCG, diphtheria-pertussis-tetanus, and measles vaccines), tetanus toxoid for the mother, vitamin A supplementation, antenatal care, skilled delivery, and safe water. Socioeconomic status was assessed through principal components analysis of household assets, and concentration indices were calculated. FINDINGS: The percentage of children who did not receive a single intervention ranged from 0.3% (14/5495) in Nicaragua to 18.8% (1154/6144) in Cambodia. The proportions receiving all available interventions varied from 0.8% (48/6144) in Cambodia to 13.3% (733/5495) in Nicaragua. There were substantial inequities within all countries. In the poorest wealth quintile, 31% of Cambodian children received no interventions and 17% only one intervention; in Haiti, these figures were 15% and 17%, respectively. Inequities were inversely related to coverage levels. Countries with higher coverage rates tended to show bottom inequity patterns, with the poorest lagging behind all other groups, whereas low-coverage countries showed top inequities with the rich substantially above the rest. INTERPRETATION: The inequitable clustering of interventions at the level of the child raises the possibility that the introduction of new technologies might primarily benefit children who are already covered by existing interventions. Packaging several interventions through a single delivery strategy, while making economic sense, could contribute to increased inequities unless population coverage is very high. Co-coverage analyses of child-health surveys provide a way to assess these issues.

WHO estimates of the causes of death in children.

BACKGROUND: Child survival efforts can be effective only if they are based on accurate information about causes of deaths. Here, we report on a 4-year effort by WHO to improve the accuracy of this information. METHODS: WHO established the external Child Health Epidemiology Reference Group (CHERG) in 2001 to develop estimates of the proportion of deaths in children younger than age 5 years attributable to pneumonia, diarrhoea, malaria, measles, and the major causes of death in the first 28 days of life. Various methods, including single-cause and multi-cause proportionate mortality models, were used. The role of undernutrition as an underlying cause of death was estimated in collaboration with CHERG. FINDINGS: In 2000-03, six causes accounted for 73% of the 10.6 million yearly deaths in children younger than age 5 years: pneumonia (19%), diarrhoea (18%), malaria (8%), neonatal pneumonia or sepsis (10%), preterm delivery (10%), and asphyxia at birth (8%). The four communicable disease categories account for more than half (54%) of all child deaths. The greatest communicable disease killers are similar in all WHO regions with the exception of malaria; 94% of global deaths attributable to this disease occur in the Africa region. Undernutrition is an underlying cause of 53% of all deaths in children younger than age 5 years. INTERPRETATION: Achievement of the millennium development goal of reducing child mortality by two-thirds from the 1990 rate will depend on renewed efforts to prevent and control pneumonia, diarrhoea, and undernutrition in all WHO regions, and malaria in the Africa region. In all regions, deaths in the neonatal period, primarily due to preterm delivery, sepsis or pneumonia, and birth asphyxia should also be addressed. These estimates of the causes of child deaths should be used to guide public-health policies and programmes.
