The impact of primary health care services on under-five mortality in rural Niger

Application of primary healthcare principles in national community health worker programmes in low-income and middle-income countries: a scoping review

OBJECTIVE

To identify which primary healthcare (PHC) principles are reflected in the implementation of national community health worker (CHW) programmes and how they may contribute to the outcomes of these programmes in the context of low-income and middle-income countries (LMICs).

DESIGN

Scoping review.

DATA SOURCES

A systematic search was conducted through PubMed, CINAHL, EMBASE and Scopus databases.

ELIGIBILITY CRITERIA

The review considered published primary studies on national programmes, projects or initiatives using the services of CHWs in LMICs focused on maternal and child health. We included only English language studies. Excluded were programmes operated by non-government organisations, study protocols, reviews, commentaries, opinion papers, editorials and conference proceedings.

DATA EXTRACTION AND SYNTHESIS

We reviewed the application of four PHC principles (universal health coverage, community participation, intersectoral coordination and appropriateness) in the CHW programme's objectives, implementation and stated outcomes. Data extraction was undertaken systematically in an excel spreadsheet while the findings were synthesised in a narrative manner. The quality appraisal of the selected studies was not performed in this scoping review.

RESULTS

From 1280 papers published between 1983 and 2019, 26 met the inclusion criteria. These 26 papers included 14 CHW programmes from 13 LMICs. Universal health coverage and community participation were the two commonly reported PHC principles, while intersectoral coordination was generally missing. Similarly, the cultural acceptability aspect of the principle of appropriateness was present in all programmes as these programmes select CHWs from within the communities. Other aspects, particularly effectiveness, were not evident.

CONCLUSION

The implementation of PHC principles across national CHW programmes in LMICs is patchy. For comprehensiveness and improved health outcomes, programmes need to incorporate all attributes of PHC principles. Future research may focus on how to incorporate more attributes of PHC principles while implementing national CHW programmes in LMICs. Better documentation and publications of CHW programme implementation are also needed.

The effects of changes in distance to nearest health facility on under-5 mortality and health care utilization in rural Malawi, 1980-1998

Background

Despite important progress, the burden of under-5 mortality remains unacceptably high, with an estimated 5.3 million deaths in 2018. Lack of access to health care is a major risk factor for under-5 mortality, and distance to health care facilities has been shown to be associated with less access to care in multiple contexts, but few such studies have used a counterfactual approach to produce causal estimates.

Methods

We combined retrospective reports on 18,714 births between 1980 and 1998 from the 2000 Malawi Demographic and Health Survey with a 1998 health facility census that includes the date of construction for each facility, including 335 maternity or maternity/dispensary facilities built in rural areas between 1980 and 1998. We estimated associations between distance to nearest health facility and (i) under-5 mortality, using Cox proportional hazards models, and (ii) maternal health care utilization (antenatal visits prior to delivery, place of delivery, receiving skilled assistance during delivery, and receiving a check-up following delivery), using linear probability models. We also estimated the causal effect of reducing the distance to nearest facility on those outcomes, using a two-way fixed effects approach.

Findings

We found that greater distance was associated with higher mortality (hazard ratio 1.007 for one additional kilometer [95%CI 1.001 to 1.014]) and lower health care utilization (for one additional kilometer: 1.2 percentage point (pp) increase in homebirth [95%CI 0.8 to 1.5]; 0.8 pp. decrease in at least three antenatal visits [95% CI − 1.4 to − 0.2]; 1.2 pp. decrease in skilled assistance during delivery [95%CI − 1.6 to − 0.8]). However, we found no effects of a decrease in distance to the nearest health facility on the hazard of death before age 5 years, nor on antenatal visits prior to delivery, place of delivery, or receiving skilled assistance during delivery. We also found that reductions in distance decrease the probability that a woman receives a check-up following delivery (2.4 pp. decrease for a 1 km decrease [95%CI 0.004 to 0.044]).

Conclusion

Reducing under-5 mortality and increasing utilization of care in rural Malawi and similar settings may require more than the construction of new health infrastructure. Importantly, the effects estimated here likely depend on the quality of health care, the availability of transportation, the demand for health services, and the underlying causes of mortality, among other factors.

Spatial Inequality Hides the Burden of Dog Bites and the Risk of Dog-Mediated Human Rabies

Since its reintroduction in 2015, rabies has been established as an enzootic disease among the dog population of Arequipa, Peru. Given the unknown rate of dog bites, the risk of human rabies transmission is concerning. Our objective was to estimate the rate of dog bites in the city and to identify factors associated with seeking health care in a medical facility for wound care and rabies prevention follow-up. To this end, we conducted a door-to-door survey with 4,370 adults in 21 urban and 21 peri-urban communities. We then analyzed associations between seeking health care following dog bites and various socioeconomic factors, stratifying by urban and peri-urban localities. We found a high annual rate of dog bites in peri-urban communities (12.4%), which was 2.6 times higher than that in urban areas (4.8%). Among those who were bitten, the percentage of people who sought medical treatment was almost twice as high in urban areas (39.1%) as in peri-urban areas (21.4%).

Determinants of healthcare seeking for childhood illnesses among caregivers of under-five children in urban slums in Malawi: a population-based cross-sectional study

BACKGROUND

There is considerable evidence that health systems, in so far as they ensure access to healthcare, promote population health even independent of other determinants. Access to child health services remains integral to improving child health outcomes. Cognisant that improvements in child health have been unevenly distributed, it is imperative that health services and research focus on the disadvantaged groups. Children residing in urban slums are known to face a health disadvantage that is masked by the common view of an urban health advantage. Granted increasing urbanisation rates and proliferation of urban slums resulting from urban poverty, the health of under-five children in slums remains a public health imperative in Malawi. We explored determinants of healthcare-seeking from a biomedical health provider for childhood symptoms of fever, cough with fast breathing and diarrhoea in three urban slums of Lilongwe, Malawi.

METHODS

This was a population-based cross-sectional study involving 543 caregivers of under-five children. Data on childhood morbidity and healthcare seeking in three months period were collected using face-to-face interviews guided by a validated questionnaire. Data were entered in CS-Pro 5.0 and analysed in SPSS version 20 using descriptive statistics and logistic regression analyses.

RESULTS

61% of caregivers sought healthcare albeit 53% of them sought healthcare late. Public health facilities constituted the most frequently used health providers. Healthcare was more likely to be sought: for younger than older under-five children (AOR = 0.54; 95% CI: 0.30-0.99); when illness was perceived to be severe (AOR = 2.40; 95% CI: 1.34-4.30); when the presenting symptom was fever (AOR = 1.77; 95% CI: 1.10-2.86). Home management of childhood illness was negatively associated with care-seeking (AOR = 0.54; 95% CI: 0.36-0.81) and timely care-seeking (AOR = 0.44; 95% CI: 0.2-0.74). Caregivers with good knowledge of child danger signs were less likely to seek care timely (AOR = 0.57; 95% CI: 0.33-0.99).

CONCLUSIONS

Even in the context of geographical proximity to healthcare services, caregivers in urban slums may not seek healthcare or when they do so the majority may not undertake timely healthcare care seeking. Factors related to the child, the type of illness, and the caregiver are central to the healthcare decision making dynamics. Improving access to under-five child health services therefore requires considering multiple factors.

Incidence of Acute Diarrhea-Associated Death among Children < 5 Years of Age in Bangladesh, 2010-12

Although acute diarrheal deaths have declined globally among children < 5 years, it may still contribute to childhood mortality as an underlying or contributing cause. The aim of this project was to estimate the incidence of acute diarrhea-associated deaths, regardless of primary cause, among children < 5 years in Bangladesh during 2010-12. We conducted a survey in 20 unions (administrative units) within the catchment areas of 10 tertiary hospitals in Bangladesh. Through social networks, our field team identified households where children < 5 years were reported to have died during 2010-12. Trained data collectors interviewed caregivers of the deceased children and recorded illness symptoms, health care seeking, and other information using an abbreviated international verbal autopsy questionnaire. We classified the deceased based upon the presence of diarrhea before death. We identified 880 deaths, of which 36 (4%) died after the development of acute diarrhea, 17 (2%) had diarrhea-only in the illness preceding death, and 19 (53%) had cough or difficulty breathing in addition to diarrhea. The estimated annual incidence of all-cause mortality in the unions < 13.6 km of the tertiary hospitals was 26 (95% confidence interval [CI] 16-37) per 1,000 live births compared with the mortality rate of 37 (95% CI 26-49) per 1,000 live births in the unions located ≥ 13.6 km. Diarrhea contributes to childhood death at a higher proportion than when considering it only as the sole underlying cause of death. These data support the use of interventions aimed at preventing acute diarrhea, especially available vaccinations for common etiologies, such as rotavirus.

Health insurance coverage and healthcare utilization among infants of mothers in the national methadone maintenance treatment program in Taiwan

BACKGROUND

Children of heroin-using women have a higher risk of unfavorable health and developmental outcomes. Although methadone maintenance treatment (MMT) has been widely used to treat heroin-using pregnant women, potential effects on accessibility and utilization of healthcare service for their offspring are less explored.

METHODS

We used four national registry and health insurance datasets in Taiwan from 2004 to 2009 to form a population-based matched retrospective cohort study. A total of 1056 neonates born to women in the MMT program (857 born before mother's enrollment in the MMT program [BM], 199 born after mother's enrollment in the MMT program [AM]) was established; 10547 matched non-drug [ND] exposed neonates were identified for comparison. Outcome variables included offspring's health insurance coverage and utilization of preventive, outpatient, and emergency room cares in the first year after birth.

RESULTS

Infants born to mothers on MMT were more likely to have no or incomplete insurance coverage (BM: adjusted odds ratio [aOR]=1.29, 95% CI: 1.10-1.53; AM: aOR=1.56, 95% CI: 1.14-2.13) as compared with the socioeconomic status-matched ND group. The BM infants appeared to have fewer preventive care visits (adjusted relative risk [aRR]=0.85, 95% CI: 0.80-0.90), whereas the AM infants utilized outpatient and emergency room services more frequently (outpatient: aRR=1.11, 95% CI: 1.01-1.23; emergency: aRR=1.46, 95% CI: 1.11-1.90).

CONCLUSIONS

Addiction treatment and harm reduction programs for women of childbearing ages should be delivered in the coordinated framework that ensures comprehensiveness and continuity in healthcare and social services.

A scoping review of training and deployment policies for human resources for health for maternal, newborn, and child health in rural Africa

BACKGROUND

Most African countries are facing a human resources for health (HRH) crisis, lacking the required workforce to deliver basic health care, including care for mothers and children. This is especially acute in rural areas and has limited countries' abilities to meet maternal, newborn, and child health (MNCH) targets outlined by Millennium Development Goals 4 and 5. To address the HRH challenges, evidence-based deployment and training policies are required. However, the resources available to country-level policy makers to create such policies are limited. To inform future HRH planning, a scoping review was conducted to identify the type, extent, and quality of evidence that exists on HRH policies for rural MNCH in Africa.

METHODS

Fourteen electronic health and health education databases were searched for peer-reviewed papers specific to training and deployment policies for doctors, nurses, and midwives for rural MNCH in African countries with English, Portuguese, or French as official languages. Non-peer reviewed literature and policy documents were also identified through systematic searches of selected international organizations and government websites. Documents were included based on pre-determined criteria.

RESULTS

There was an overall paucity of information on training and deployment policies for HRH for MNCH in rural Africa; 37 articles met the inclusion criteria. Of these, the majority of primary research studies employed a variety of qualitative and quantitative methods. Doctors, nurses, and midwives were equally represented in the selected policy literature. Policies focusing exclusively on training or deployment were limited; most documents focused on both training and deployment or were broader with embedded implications for the management of HRH or MNCH. Relevant government websites varied in functionality and in the availability of policy documents.

CONCLUSIONS

The lack of available documentation and an apparent bias towards HRH research in developed areas suggest a need for strengthened capacity for HRH policy research in Africa. This will result in enhanced potential for evidence uptake into policy. Enhanced alignment between policy-makers' information needs and the independent research agenda could further assist knowledge development and uptake. The results of this scoping review informed an in-depth analysis of relevant policies in a sub-set of African countries.

Inpatient child mortality by travel time to hospital in a rural area of Tanzania

OBJECTIVE

To investigate the association, if any, between child mortality and distance to the nearest hospital.

METHODS

The study was based on data from a 1-year study of the cause of illness in febrile paediatric admissions to a district hospital in north-east Tanzania. All villages in the catchment population were geolocated, and travel times were estimated from availability of local transport. Using bands of travel time to hospital, we compared admission rates, inpatient case fatality rates and child mortality rates in the catchment population using inpatient deaths as the numerator.

RESULTS

Three thousand hundred and eleven children under the age of 5 years were included of whom 4.6% died; 2307 were admitted from <3 h away of whom 3.4% died and 804 were admitted from ≥3 h away of whom 8.0% died. The admission rate declined from 125/1000 catchment population at <3 h away to 25/1000 at ≥3 h away, and the corresponding hospital deaths/catchment population were 4.3/1000 and 2.0/1000, respectively. Children admitted from more than 3 h away were more likely to be male, had a longer pre-admission duration of illness and a shorter time between admission and death. Assuming uniform mortality in the catchment population, the predicted number of deaths not benefiting from hospital admission prior to death increased by 21.4% per hour of travel time to hospital. If the same admission and death rates that were found at <3 h from the hospital applied to the whole catchment population and if hospital care conferred a 30% survival benefit compared to home care, then 10.3% of childhood deaths due to febrile illness in the catchment population would have been averted.

CONCLUSIONS

The mortality impact of poor access to hospital care in areas of high paediatric mortality is likely to be substantial although uncertainty over the mortality benefit of inpatient care is the largest constraint in making an accurate estimate.

Predicting mortality for paediatric inpatients where malaria is uncommon

OBJECTIVE

As the proportion of children living low malaria transmission areas in sub-Saharan Africa increases, approaches for identifying non-malarial severe illness need to be evaluated to improve child outcomes.

DESIGN

As a prospective cohort study, we identified febrile paediatric inpatients, recorded data using Integrated Management of Childhood Illness (IMCI) criteria, and collected diagnostic specimens.

SETTING

Tertiary referral centre, northern Tanzania.

RESULTS

Of 466 participants with known outcome, median age was 1.4 years (range 2 months-13.0 years), 200 (42.9%) were female, 11 (2.4%) had malaria and 34 (7.3%) died. Inpatient death was associated with: Capillary refill >3 s (OR 9.0, 95% CI 3.0 to 26.7), inability to breastfeed or drink (OR 8.9, 95% CI 4.0 to 19.6), stiff neck (OR 7.0, 95% CI 2.8 to 17.6), lethargy (OR 5.2, 95% CI 2.5 to 10.6), skin pinch >2 s (OR 4.8, 95% CI 1.9 to 12.3), respiratory difficulty (OR 4.0, 95% CI 1.9 to 8.2), generalised lymphadenopathy (OR 3.6, 95% CI 1.6 to 8.3) and oral candidiasis (OR 3.4, 95% CI 1.4 to 8.3). BCS <5 (OR 27.2, p<0.001) and severe wasting (OR 6.9, p<0.001) were independently associated with inpatient death.

CONCLUSIONS

In a low malaria transmission setting, IMCI criteria performed well for predicting inpatient death from non-malarial illness. Laboratory results were not as useful in predicting death, underscoring the importance of clinical examination in assessing prognosis. Healthcare workers should consider local malaria epidemiology as malaria over-diagnosis in children may delay potentially life-saving interventions in areas where malaria is uncommon.

Association between proximity to a health center and early childhood mortality in Madagascar

Objective

To evaluate the association between proximity to a health center and early childhood mortality in Madagascar, and to assess the influence of household wealth, maternal educational attainment, and maternal health on the effects of distance.

Methods

From birth records of subjects in the Demographic and Health Survey, we identified 12565 singleton births from January 2004 to August 2009. After excluding 220 births that lacked global positioning system information for exposure assessment, odds ratios (ORs) and their 95% confidence intervals (CIs) for neonatal mortality and infant mortality were estimated using multilevel logistic regression models, with 12345 subjects (level 1), nested within 584 village locations (level 2), and in turn nested within 22 regions (level 3). We additionally stratified the subjects by the birth order. We estimated predicted probabilities of each outcome by a three-level model including cross-level interactions between proximity to a health center and household wealth, maternal educational attainment, and maternal anemia.

Results

Compared with those who lived >1.5–3.0 km from a health center, the risks for neonatal mortality and infant mortality tended to increase among those who lived further than 5.0 km from a health center; the adjusted ORs for neonatal mortality and infant mortality for those who lived >5.0–10.0 km away from a health center were 1.36 (95% CI: 0.92–2.01) and 1.42 (95% CI: 1.06–1.90), respectively. The positive associations were more pronounced among the second or later child. The distance effects were not modified by household wealth status, maternal educational attainment, or maternal health status.

Conclusions

Our study suggests that distance from a health center is a risk factor for early childhood mortality (primarily, infant mortality) in Madagascar by using a large-scale nationally representative dataset. The accessibility to health care in remote areas would be a key factor to achieve better infant health.

Proximity to health services and child survival in low- and middle-income countries: a systematic review and meta-analysis

OBJECTIVES

Few studies have systematically examined the effects of barriers such as distance to health facilities on child survival in low- and middle-income countries. Our primary objective was to estimate the effect of proximity to health facilities on child survival in low- and middle-income countries. The secondary objective was to compare effects in different age categories (perinatal (28 weeks of gestation to 1 week of age), neonatal (0-27 days), infant (0-11 months) and child (0-59 months) mortality).

DESIGN

A systematic review and meta-analysis was conducted of studies published from 1980 to 2012 that assessed the effect of proximity to health facilities on child survival in low- and middle-income countries. Synthesis was by random-effects meta-analysis, and variation between studies was investigated by meta-regression.

SETTING

Low- and middle-income countries.

PARTICIPANTS

13 studies were included in the meta-analysis, 11 from low-income and two from middle-income countries and none were from remote areas.

PRIMARY OUTCOME MEASURES

The primary outcome measures of interest were perinatal, neonatal, infant and child mortality.

RESULTS

Overall, children who lived farthest from health facilities were more likely to die compared with those who lived closer (OR 1.32, 95% CI 1.19 to 1.47). This effect appeared stronger during the perinatal (OR 2.76, 95% CI 1.80 to 4.24) and neonatal (OR 1.98, 95% CI 1.43 to 2.72) periods compared with the infant (OR 1.18, 95% CI 1.0 to 1.38) and under-5 (OR 1.20, 95% CI 1.04 to 1.39) periods.

CONCLUSIONS

Proximity to health facilities appears to be an important determinant of under-5 mortality in low- and middle-income countries, especially in the perinatal and neonatal periods. Higher quality studies are needed, which examine the effect of access to health services on child survival, especially studies from remote areas and hard to reach populations.

Access and quality of rural healthcare: Ethiopian Millennium Rural Initiative

OBJECTIVE

More than half the world's population lives in rural areas; however, we have limited evidence about how to strengthen rural healthcare services. We sought to determine the impact of a systems-based approach to improving rural care, the Ethiopian Millennium Rural Initiative, on key healthcare services indicators.

DESIGN

We conducted an 18-month longitudinal mixed methods study of the 10 primary healthcare units (PHCUs) serving ~400,000 people, using monthly indicator tracking and focus groups.

SETTING

Rural Ethiopia.

PARTICIPANTS

Ten PHCUs and 140 focus group participants.

INTERVENTION

The Ethiopian Millennium Rural Initiative.

MAIN OUTCOME MEASURES

Antenatal care coverage, skilled birth attendant rates, HIV testing in antenatal care, HIV testing in the health center or at health posts overall, outpatient volume at the health center. Qualitative data assessed community members' perceptions of healthcare services.

RESULTS

We found significant increases (P-values of <0.05) in antenatal care coverage, skilled birth attendant rates, HIV testing in antenatal care and HIV testing at health center and health post levels. Outpatient visit rates also improved, but the change was not significant. Focus group data suggested that communities recognized substantial improvements but also voiced continued unmet needs.

CONCLUSIONS

A systems-based approach to strengthening rural healthcare units is feasible, although complex, particularly in rural settings. The combined use of quantitative and qualitative data is needed to provide a comprehensive view of impact. Future research is needed to understand the determinants of variation in improvement across health centers and regions.

The effect of distance to health-care facilities on childhood mortality in rural Burkina Faso

This study aims to investigate the relation between distance to health facilities, measured as continuous travel time, and mortality among infants and children younger than 5 years of age in rural Burkina Faso, an area with low health facility density. The study included 24,555 children born between 1993 and 2005 in the Nouna Health and Demographic Surveillance System. The average walking time from each village to the closest health facility was obtained for both the dry and the rainy season, and its effect on infant (<1 year), child (1-4 years), and under-5 mortality overall was analyzed by Cox regression. The authors observed 3,426 childhood deaths, corresponding to a 5-year survival of 85%. Walking distance was significantly related to both infant and child mortality, although the shape of this effect varied distinctly between the 2 age groups. Overall, under-5 mortality, adjusted for confounding, was more than 50% higher at a distance of 4 hours compared with having a health facility in the village (P < 0.0001, 2 sided). The region of residence was an additional determinant for under-5 mortality. The findings of this study emphasize the importance of geographic accessibility of health care for child survival in sub-Saharan Africa and demonstrate the need to improve health-care access to achieve the Millennium Development Goals.

Changing poor mothers' care-seeking behaviors in response to childhood illness: findings from a cross-sectional study in Granada, Nicaragua

BACKGROUND

In 2008, approximately 8.8 million children under 5 years of age died worldwide. Most of these deaths occurred in developing countries, but little is known about poor mothers' care-seeking behaviors for their children.We examined poor mothers' care-seeking behaviors in response to childhood illness, and identified factors affecting their choices. We also assessed mothers' perception of the medical services and their confidence in the health care available for their children.

METHODS

We carried out a community-based cross-sectional study with structured questionnaires. Participants were 756 mothers and their young children (0-23 months) in Nandaime municipality, Granada province, Nicaragua. We took the children's anthropometric measurements and we assessed the mothers according to their income. We divided them into 3 global absolute poverty categories (income: <1 USD/day, 1-2 USD/day, >2 USD/day), and 4 quintile.

RESULTS

When a child showed symptoms of illness, most mothers (>75%) selected public health facilities as their first choice. More than half (>58%) were satisfied with the medical services, but the poorest mothers expressed more dissatisfaction (p = 0.003), when we divided the participants into 4 quintiles groups according to their income. In the poorest group, the main reasons for dissatisfaction were cost (46.6%), and distance to the facilities (25.8%). Almost half (41.3%) of mothers lacked confidence in the health care offered to their child, while most of the wealthiest mothers (75.7%) did have confidence in it (p = 0.001). The poorest mothers showed greater interest in health education than the wealthiest (86.2% vs. 77.8%) (p = 0.015). We found that poor mothers (

CONCLUSIONS

Determination of the severity of a childhood disease is a difficult task for mothers. The national rural health system was functioning, yet the services were often limited. We should consider the feasibility of providing a more effective primary care system for the poor.To encourage mothers' care-seeking behaviors in poor settings, the referral system and the social safety net need to be strengthened. Poor mothers need further education about the danger signs of childhood illness.

How access to health care relates to under-five mortality in sub-Saharan Africa: systematic review

An estimated 9.7 million children under the age of five die every year worldwide, approximately 41% of them in sub-Saharan Africa (SSA). Access to adequate health care is among the factors suggested to be associated with child mortality; improved access holds great potential for a significant reduction in under-five death in developing countries. Theory and corresponding frameworks indicate a wide range of factors affecting access to health care, such as traditionally measured variables (distance to a health provider and cost of obtaining health care) and additional variables (social support, time availability and caregiver autonomy). Few analytical studies of traditional variables have been conducted in SSA, and they have significant limitations and inconclusive results. The importance of additional factors has been suggested by qualitative and recent quantitative studies. We propose that access to health care is multidimensional; factors other than distance and cost need to be considered by those planning health care provision if child mortality rates are to be reduced through improved access. Analytical studies that comprehensively evaluate both traditional and additional variables in developing countries are required.

The contribution of primary care to health and health systems in low- and middle-income countries: a critical review of major primary care initiatives

It has been 30 years since the Declaration of Alma Ata. During that time, primary care has been the central strategy for expanding health services in many low- and middle-income countries. The recent global calls to redouble support for primary care highlighted it as a pathway to reaching the health Millennium Development Goals. In this systematic review we described and assessed the contributions of major primary care initiatives implemented in low- and middle-income countries in the past 30 years to a broad range of health system goals. The scope of the programs reviewed was substantial, with several interventions implemented on a national scale. We found that the majority of primary care programs had multiple components from health service delivery to financing reform to building community demand for health care. Although given this integration and the variable quality of the available research it was difficult to attribute effects to the primary care component alone, we found that primary care-focused health initiatives in low- and middle-income countries have improved access to health care, including among the poor, at reasonably low cost. There is also evidence that primary care programs have reduced child mortality and, in some cases, wealth-based disparities in mortality. Lastly, primary care has proven to be an effective platform for health system strengthening in several countries. Future research should focus on understanding how to optimize the delivery of primary care to improve health and achieve other health system objectives (e.g., responsiveness, efficiency) and to what extent models of care can be exported to different settings.

The role of community health workers in improving child health programmes in Mali

BACKGROUND

Mortality of children under the age of five remains one of the most important public health challenges in developing countries. In rural settings, the promotion of household and community health practices through community health workers (CHWs) is among the key strategies to improve child health. The objective of this study was to assess the performance of CHWs in the promotion of basic child heath services in rural Mali.

METHODS

A community-based cross-sectional survey was undertaken using multi-stage cluster sampling of wards and villages. Data was collected through questionnaires among 401 child-caregivers and registers of 72 CHWs.

RESULTS

Of 401 households suppose to receive a visit by a CHW, 219 (54.6%; confidence interval 95%; 49.6-59.5) had received at least one visit in the last three months before the survey. The mother is the most important caregiver (97%); high percentage being illiterate. Caregivers treat fever and diarrhoea with the correct regimen in 40% and 11% of cases respectively. Comparative analysis between households with and without CHW visits showed a positive influence of CHWs on family health practices: knowledge on the management of child fever (p = < 0.001), non-utilization of antibiotics in home treatment of diarrhoea (p = 0.003), presence of cloroquine in the household (p = 0.002), presence (p = 0.001) and use (p = < 0.001) of bed nets. A total of 27 (38%) CHWs had not received supervision at all, against 45 (63%) who have been followed regularly each month during the last six months.

CONCLUSION

Continuous training, transport means, adequate supervision and motivation of CHWs through the introduction of financial incentives and remuneration are among key factors to improve the work of CHWs in rural communities. Poor performance of basic household health practices can be related to irregular supply of drugs and the need of appropriate follow-up by CHWs.

Access to health care and mortality of children under 5 years of age in the Gambia: a case-control study

OBJECTIVE

To assess whether traditional measures of access to health care (distance and travel time to a facility) and non-traditional measures (social and financial support indicators) are associated with mortality among children under 5 years of age in the Gambia.

METHODS

We conducted a case-control study in a population under demographic surveillance. Cases (n = 140) were children under 5 years of age who died between 31 December 2003 and 30 April 2006. Each case was matched in age and sex to five controls (n = 700). Information was gathered by interviewing primary caregivers. The data were analysed using conditional logistic regression.

FINDINGS

Of traditional measures of access, only rural versus urban/periurban residence was important: children from rural areas were more likely to die (OR: 4.9; 95% confidence interval, CI: 1.2-20.2). For non-traditional measures, children were more likely to die if their primary caregivers lacked help with meal preparation (OR: 2.3; 95% CI: 1.2-4.1), had no one to relax with (OR: 1.8; 95% CI: 1.1-2.9), had no one who could offer good advice (OR: 23.1; 95% CI: 4.3-123.4), had little say over how earned money was spent (OR: 12.7; 95% CI: 1.3-127.6), were unable to cut spending for health care (OR: 2.5; 95% CI: 1.5-4.2) or had to carry out odd jobs to pay for the care (OR: 3.4; 95% CI: 2.1-5.5). A protective effect was observed when the caregiver had other children to care for (OR: 0.2; 95% CI: 0.1-0.5).

CONCLUSION

Improving access to health-care for children in the Gambia and similar settings is not simply a matter of reducing travel time and distance to a health facility, but requires improvements in caregivers' support networks and their access to the financial resources they need.

The impact of primary healthcare on population health in low- and middle-income countries

This article assesses 36 peer-reviewed studies of the impact of primary healthcare (PHC) on health outcomes in low- and middle-income countries. Studies were abstracted and assessed according to where they took place, the research design used, target population, primary care measures, and overall conclusions. Results indicate that the bulk of evidence for PHC effectiveness is focused on infant and child health, but there is also evidence of the positive role PHC has on population health over time. Although the peer-reviewed literature is lacking in rigorous experimental studies, a small number of relatively well-designed observational studies and the consistency of findings generally support the contention that an integrated approach to primary care can improve health. A few large-scale experiences also help identify elements of good practice. The review concludes with several recommendations for future studies, including a focus on better conceptualizing and measuring PHC, further investigation into the advantages of comprehensive over selective PHC, need for experimental or quasi-experimental research designs that allow testing of the independent effect of primary care on outcomes over time, and a more detailed conceptual framework guiding overall evaluation design that places limits on the parameters under consideration and describes relationships among different levels and types of data likely to be collected in the evaluation process.

Decline of mortality in children in rural Gambia: the influence of village-level primary health care

Using data from a longitudinal study conducted in 40 villages by the UK MRC in the North Bank Division of The Gambia beginning in late 1981, we examined infant and child mortality over a 15-year period for a population of about 17 000 people. Comparisons are drawn between villages with and without PHC. The extra facilities in the PHC villages include: a paid Community Health Nurse for about every 5 villages, a Village Health Worker and a trained Traditional Birth Attendant. Maternal and child health services with a vaccination programme are accessible to residents in both PHC and non-PHC villages. The data indicate that there has been a marked improvement in infant and under-five mortality in both sets of villages. Following the establishment of the PHC system in 1983, infant mortality dropped from 134/1000 in 1982-83 to 69/1000 in 1992-94 in the PHC villages and from 155/1000 to 91/1000 in the non-PHC villages over the same period. Between 1982 and 83 and 1992-94, the death rates for children aged 1-4 fell from 42/1000 to 28/1000 in the PHC villages and from 45/1000 to 38/1000 in the non-PHC villages. Since 1994, when supervision of the PHC system has weakened, infant mortality rates in the PHC villages have risen to 89/1000 in 1994-96. The rates in the non-PHC villages fell to 78/1000 for this period. The under-five mortality rates in both sets of villages have converged to 34/1000 for 1994-96. When the PHC programme was well supported in the 1980s, we saw significantly lower mortality rates for the 1-4-year-olds. These differences disappeared when support for PHC was reduced after 1994. The differential effects on infant mortality are less clear cut.
