Documenting the development, adoption and pre-ebola implementation of Liberia's integrated disease surveillance and response (IDSR) strategy.

BACKGROUND: In the immediate aftermath of a 14-year civil conflict that disrupted the health system, Liberia adopted the internationally recommended integrated disease surveillance and response (IDSR) strategy in 2004. Despite this, Liberia was among the three West African countries ravaged by the worst Ebola epidemic in history from 2014 to 2016. This paper describes successes, failures, strengths, and weaknesses in the development, adoption, and implementation of IDSR following the civil war and up until the outbreak of Ebola, from 2004 to early 2014. METHODS: We reviewed 112 official Government documents and peer-reviewed articles and conducted 29 in-depth interviews with key informants from December 2021 to March 2022 to gain perspectives on IDSR in the post-conflict and pre-Ebola era in Liberia. We assessed the core and supportive functions of IDSR, such as notification of priority diseases, confirmation, reporting, analysis, investigation, response, feedback, monitoring, staff training, supervision, communication, and financial resources. Data were triangulated and presented via emerging themes and in-depth accounts to describe the context of IDSR introduction and implementation, and the barriers surrounding it. RESULTS: Despite the adoption of the IDSR framework, Liberia failed to secure the resources-human, logistical, and financial-to support effective implementation over the 10-year period. Documents and interview reports demonstrate numerous challenges prior to Ebola: the surveillance system lacked key components of IDSR including laboratory testing capacity, disease reporting, risk communication, community engagement, and staff supervision systems. Insufficient financial support and an abundance of vertical programs further impeded progress. In-depth accounts by donors and key governmental informants demonstrate that although the system had a role in detecting Ebola in Liberia, it could not respond effectively to control the disease. CONCLUSION: Our findings suggest that post-war, Liberia's health system intended to prioritize epidemic preparedness and response with the adoption of IDSR. However, insufficient investment and systems development meant IDSR was not well implemented, leaving the country vulnerable to the devastating impact of the Ebola epidemic.

Factors associated with underweight, overweight, stunting and wasting among primary school-going children participating in a school health initiative in South Africa.

BACKGROUND: The double burden of malnutrition among children remains a public health challenge in South Africa. In response, the government of South Africa developed the National Health Policy and Implementation Guidelines for school-going children in 2003. This policy was subsequently upgraded to 'The Integrated School Health Programme' in 2012. An element of the programme is the provision of a meal to school-going children on school days. However, evidence suggests that one-third of school-going children continue to have nutritional deficiencies. This study investigated the sociodemographic as well as the nutritional characteristics of school-going children participating in a school health initiative in KwaZulu-Natal Province, South Africa. METHODS: This was a retrospective descriptive cross-sectional study involving 1,275 children (50.3% females and 49.7% males) aged 3 to 15 years. Epidemiological data on the screening of the children's nutritional characteristics by school health nurses and school health nutritionists under the integrated school health programme (ISHP) was reviewed and analysed for the study. RESULTS: Nearly half (50.3%) and 49.7% of the population were females and males, respectively. The average age of participants was 8.4 years old. 'Underweight' (p = 0.000), 'overweight' (p = 0.000), 'at risk of overweight' (p = 0.000),'stunting' (p = 0.000),'severe stunting' (p = 0.005), 'wasting' (p = 0.010), and 'obesity' (p = 0.037) were associated with the 'schools that children attended'. School-going children' living conditions were significantly associated with 'normal weight' (p = 0.000), 'underweight' (p = 0.000), and 'underweight' (p = 0.028). However, the social grant to parents/guardians had some positive effects on the percentage of children who reported 'normal weight' (55.4%), 'wasting' (1.0%), 'underweight' (4.0%), and 'at risk of overweight' (20.2%). CONCLUSION: Chronic nutritional deficiencies persist among children. Therefore, ISHP implementation must retarget specific regions of the country to ensure that national goals and gains on school-going children nutrition, are met and maintained. Indeed, considering the positive impact of the government's social grant programme on the nutritional status of the children in this study, we recommend policy reforms that will increase parents' and carers' access to means of subsistence in order to meet the health and nutritional needs of children in the study communities.

Community Health Worker programmes' integration into national health systems: Scoping review.

BACKGROUND: Community health worker (CHW) programmes, when adequately integrated into mainstream health systems, can provide a viable, affordable and sustainable path to strengthened health systems that better meets demands for improved child health, especially in resource-constrained settings. However, studies that report on how CHW programmes are integrated into respective health systems in sub-Saharan Africa (SSA) are missing. AIM: This review presents evidence on CHW programmes' integration into National Health Systems for improved health outcomes in SSA. SETTING: Sub-Saharan Africa. METHOD: Six CHW programmes representing three sub-Saharan regions (West, East, and Southern Africa) were purposively selected based on their deemed integration into respective National Health Systems. A database search of literature limited to the identified programmes was then conducted. Screening and literature selection was guided a scoping review framework. Abstracted data were synthesised and presented in a narrative form. RESULTS: A total of 42 publications met the inclusion criteria. Reviewed papers had an even focus on all six CHW programmes integration components. Although some similarities were observed, evidence of integration on most CHW programme integration components varied across countries. The linkage of CHW programmes to respective health systems runs across all reviewed countries. Some CHW programme components such as CHW recruitment, education and certification, service delivery, supervision, information management, and equipment and supplies are integrated into the health systems differently across the region. CONCLUSION: Different approaches to the integration of all the components depict complexity in the field of CHW programme integration in the region.Contribution: The study presents synthesized evidence on CHW programmes integration into national health systems in SSA.

Health systems strengthening through policy-level integration of community health worker programs into national health systems for improved health outcomes - scorecard metrics validation: A bifactor structural equation model approach.

Background: Subsequent to the demonstrated potential of community health workers (CHWs) in strengthening health systems to improve health outcomes, recent literature has defined context and guidelines for integrating CHW programs into mainstream health systems. However, quantitative measures for assessing the extent of CHW program integration into national health systems need to be developed. The purpose of this study was to validate a newly developed scale, Community Health Worker Program Integration Scorecard Metrics (CHWP-ISM), for assessing the degree of integration of CHW programs into national health systems in Sub-Saharan Africa (SSA). Methods: Data obtained through a pilot study involving a purposively selected sample of 41 participants selected from populations involved in CHW programs work in selected countries of SSA formed the basis of a 31-item bifactor model. Data were collected between June and December 2019. By applying a latent variable approach implemented with structural equation modeling, data analysis was mainly done using the R statistical environment, applying factor analysis procedures. Results: Dimensionality, construct validity, and the CHWP-ISM scale's internal consistency were assessed. Confirmatory factor analysis of the CHW-ISM bifactor model supported a co-occurring CHW integration general factor and six unique domain-specific factors. Both the comparative fit index (CFI) and Tucker-Lewis Index (TLI) fit indices were above 0.9, while the root mean square of the residuals (RMSR) was 0.02. Cronbach's alpha (α), Guttman 6 (Lambda 6), and Omega total (ωt) were above 0.8, indicating good scale reliability. Conclusion: Statistical significance of the bifactor model suggests that CHW integration has to be examined using factors that reflect a single common underlying integration construct, as well as factors that reflect unique variances for the identified six subject-specific domains. The validated CHWP-ISM could be useful to inform policy advisers, health systems, donors, non-governmental organizations, and other CHW program stakeholders with guidance on how to quantitatively assess the integration status of different components of CHW programs into respective critical functions of the health system. Improved integration could increase CHW program functionality, which could in turn strengthen the healthcare systems to improve health outcomes in the region.

Scorecard metrics for assessing the extent of integration of community health worker programmes into national health systems.

BACKGROUND: The effectiveness of community health workers (CHWs) in delivering community-based preventive services is often curtailed by inadequate or complete lack of integration of the CHW programmes into national health systems. Although literature has defined the context and guidelines for integrating CHW programmes into health systems, indicators to quantitatively assess the extent of integration are inadequately addressed. AIM: This article presents an integration scale - CHW Programme Integration Scorecard Metrics (CHWP-ISM) - for measuring the extent of CHW programme integration into national health systems. SETTING: Literature review and policy documents were focused on sub-Saharan Africa, while interview participants were drawn from six African countries. METHODS: A deductive-inductive approach to item and measurement scale development was employed. Information obtained from a combination of diverse literature sources, subject matter expert (SME) interviews and documentary abstraction from publicly available policy documents advised item generation for the proposed CHWP-ISM. The study qualitatively captured the sectoral CHW integration, thematically analysed the data and culminated in the quantitative integration metrics. RESULTS: Analysis of the responses from six SMEs and abstraction from policy documents resulted in the compilation of metrics with a total of 100 indicators for the CHWP-ISM scale that could be used to assess the level of CHW programmes integration into national health systems. The indicators were categorised along the six World Health Organization's (WHO) health systems building blocks. Subject matter expert responses corresponded well with abstracted results from the 18 country CHW programmes, indicating content validity. CONCLUSION: The proposed scorecard metrics can be used to quantitatively rate the extent of CHW programmes integration into health systems, in an attempt to strengthen health systems to improve health outcomes.

Factors hindering health care delivery in nomadic communities: a cross-sectional study in Timbuktu, Mali.

BACKGROUND: In Mali, nomadic populations are spread over one third of the territory. Their lifestyle, characterized by constant mobility, excludes them from, or at best places them at the edge of, health delivery services. This study aimed to describe nomadic populations' characteristics, determine their perception on the current health services, and identify issues associated with community-based health interventions. METHODS: To develop a better health policy and strategic approaches adapted to nomadic populations, we conducted a cross-sectional study in the region of Timbuktu to describe the difficulties in accessing health services. The study consisted in administering questionnaires to community members in the communes of Ber and Gossi, in the Timbuktu region, to understand their perceptions of health services delivery in their settings. RESULTS: We interviewed 520 individuals, all members of the nomadic communities of the two study communes. Their median age was 38 years old with extremes ranging from 18 to 86 years old. Their main activities were livestock breeding (27%), housekeeping (26.4%), local trading (11%), farming (6%) and artisans (5.5%). The average distance to the local health center was 40.94 km and 23.19 km respectively in Gossi and Ber. In terms of barriers to access to health care, participants complained mainly about the transportation options (79.4%), the quality of provided services (39.2%) and the high cost of available health services (35.7%). Additionally, more than a quarter of our participants stated that they would not allow themselves to be examined by a health care worker of the opposite gender. CONCLUSION: This study shows that nomadic populations do not have access to community-based health interventions. A number of factors were revealed to be important barriers per these communities' perception including the quality of services, poverty, lifestyle, gender and current health policy strategies in the region. To be successful, future interventions should take these factors into account by adapting policies and methods.

A cluster randomized trial of delivery of intermittent preventive treatment of malaria in pregnancy at the community level in Burkina Faso.

BACKGROUND: Malaria in pregnancy is responsible for 8-14% of low birth weight and 20% of stillbirths in sub-Saharan Africa. To prevent these adverse consequences, the World Health Organization recommends intermittent preventive treatment of pregnant women (IPTp) with sulfadoxine-pyrimethamine be administered at each ANC visit starting as early as possible in the second trimester. Global IPTp coverage in targeted countries remains unacceptably low. Community delivery of IPTp was explored as a means to improve coverage. METHODS: A cluster randomized, controlled trial was conducted in 12 health facilities in a 1:1 ratio to either an intervention group (IPTp delivered by CHWs) or a control group (standard practice, with IPTp delivered at HFs) in three districts of Burkina Faso to assess the effect of IPTp administration by community health workers (CHWs) on the coverage of IPTp and antenatal care (ANC). The districts and facilities were purposively selected taking into account malaria epidemiology, IPTp coverage, and the presence of active CHWs. Pre- and post-intervention surveys were carried out in March 2017 and July-August 2018, respectively. A difference in differences (DiD) analysis was conducted to assess the change in coverage of IPTp and ANC over time, accounting for clustering at the health facility level. RESULTS: Altogether 374 and 360 women were included in the baseline and endline surveys, respectively. At baseline, women received a median of 2.1 doses; by endline, women received a median of 1.8 doses in the control group and 2.8 doses in the intervention group (p-value < 0.0001). There was a non-statistically significant increase in the proportion of women attending four ANC visits in the intervention compared to control group (DiD = 12.6%, p-value = 0.16). By the endline, administration of IPTp was higher in the intervention than control, with a DiD of 17.6% for IPTp3 (95% confidence interval (CI) - 16.3, 51.5; p-value 0.31) and 20.0% for IPTp4 (95% CI - 7.2, 47.3; p-value = 0.15). CONCLUSIONS: Community delivery of IPTp could potentially lead to a greater number of IPTp doses delivered, with no apparent decrease in ANC coverage.

Community health workers provide integrated community case management using malaria rapid diagnostic test kits.

BACKGROUND: Throughout Nigeria malaria is an endemic disease. Efforts to treat malaria can also be combined with other illnesses including pneumonia and diarrhea, which are killing children under five years of age. The use of Rapid Diagnostic Test (RDT) aids early diagnosis of malaria and informs when other illnesses should be considered. Those with positive RDT results should be treated with Artemisinin-based Combination Therapy (ACTs), while those with negative RDTs results are further investigated for pneumonia and diarrhea. Critical health systems challenges such as human resource constraints mean that community case management (CCM) and community health workers such as volunteers called Community Directed Distributors (CDDs) can therefore play an important role in diagnosing and treating malaria. This repost described an effort to monitor and document the performance of trained CDDs in providing quality management of febrile illnesses including the use of RDTs. METHOD: The program trained one hundred and fifty-two (152) CDDs on the use of RDTs to test for malaria and give ACTs for positive RDTs results, cotrimoxazole for the treatment of pneumonia and Oral rehydration solution and zinc for diarrhea They were also taught to counsel on compliance medicine, identify adverse reactions, and keep accurate records. The CDDs worked for 12 Calendar months. Their registers were retrieved and audited using a checklist to document client complaints, tests done, test results and treatment provided. No client identifying information was collected. RESULTS: There were 32 (21%) male CDDs and 120 (79%) females. The overall mean age of the CDDs was 36.8 (±8.7) years old. 89% of the male CDDs provided correct treatment based on RDT results compared to 97.6% of the female CDDs, a statistically significant difference. Likewise CDDs younger than 36 years of age provided 92.7% correct case management compared to those 36 years and older (98.4%). The difference between the age groups was also significant. There was a strong association between CDDs dispensing ACTs with positive RDT results. In RDT negative cases, the most common course of action was dispensing antibiotics (43.2%), followed by referring the patients (30.34%) and the providing ORS (24.1%). CONCLUSION: Volunteer CDDs who are community members can adhere to treatment protocols and guidelines and comply with performance standards. The next step is scaling this approach to a state-wide level.

Providing Universal Health Insurance Coverage in Nigeria.

Despite a stated goal of achieving universal coverage, the National Health Insurance Scheme of Nigeria had achieved only 4% coverage 12 years after it was launched. This study assessed the plans of the National Health Insurance Scheme to achieve universal health insurance coverage in Nigeria by 2015 and discusses the challenges facing the scheme in achieving insurance coverage. In-depth interviews from various levels of the health-care system in the country, including providers, were conducted. The results of the analysis suggest that challenges to extending coverage include the difficulty in convincing autonomous state governments to buy into the scheme and an inadequate health workforce that might not be able to meet increased demand. Recommendations for increasing the scheme's coverage include increasing decentralization and strengthening human resources for health in the service delivery systems. Strong political will is needed as a catalyst to achieving these goals.

Determinants of Utilization and Community Experiences with Community Health Volunteers for Treatment of Childhood Illnesses in Rural Sierra Leone.

In 2010, at the same time as the national roll out of the Free Health Care Initiative (FHCI), which removed user fees for facility based health care, trained community health volunteers (CHVs) were deployed to provide integrated community case management of diarrhea, malaria and pneumonia to children under 5 years of age (U5) in Kambia and Pujehun districts, Sierra Leone. After 2 years of implementation and in the context of FHCI, CHV utilization rate was 14.0 %. In this study, we examine the factors associated with this level of CHV utilization. A cross-sectional household-cluster survey of 1590 caregivers of 2279 children U5 was conducted in 2012; with CHV utilization assessed using a multiple logistic regression model. Focus groups and in-depth interviews were also conducted to understand communities' experiences with CHVs. Children with diarrhea (OR = 3.17, 95 % CI: 1.17-8.60), from female-headed households (OR = 4.55, 95 % CI: 1.88-11.00), and whose caregivers reported poor quality of care as a barrier to facility care-seeking (OR = 8.53, 95 % CI: 3.13-23.16) were more likely to receive treatment from a CHV. Despite low utilization, caregivers were highly familiar and appreciative of CHVs, but were concerned about the lack of financial remuneration for CHVs. CHVs remained an important source of care for children from female-headed households and whose caregivers reported poor quality of care at health facilities. CHVs are an important strategy for certain populations even when facility utilization is high or when facility services are compromised, as has happened with the recent Ebola epidemic in Sierra Leone.

The Potential for Community-Directed Interventions: Reaching Underserved Populations in Africa.

Community-directed interventions (CDIs) have the potential for fulfilling the promise of primary health care by reaching underserved populations in various settings. CDI has been successfully tested by expanding access to additional health services like malaria case management through local effort in communities where ivermectin distribution is ongoing. The question remains whether the CDI approach has potential in communities that do not have a foundation of community-directed treatment with ivermectin. The UNICEF/UNDP/World Bank/WHO Special Program of Research and Training in Tropical Diseases commissioned three sets of formative studies to explore the potential for introducing CDI among nomads, urban poor, and rural areas with no community-directed treatment with ivermectin. This article reviews their findings. Community and health system respondents identified a set of mainly communicable diseases that could be adapted to CDI as well as participatory mechanisms like community-based organizations and leaders that could form a foundation for local organizing and participation. It is hoped that the results of these formative studies will spur further research on CDI among peoples with poor health-care access.

Influence of community health volunteers on care seeking and treatment coverage for common childhood illnesses in the context of free health care in rural Sierra Leone.

OBJECTIVE: To examine whether community health volunteers induced significant changes in care seeking and treatment of ill children under five 2 years after their deployment in two underserved districts of Sierra Leone. METHODS: A pre-test-post-test study with intervention and comparison groups was used. A household cluster survey was conducted among caregivers of 5643 children at baseline and of 5259 children at endline. RESULTS: In the intervention districts, treatments provided by community health volunteers increased from 0 to 14.3% for all three conditions combined (P < 0.001). Care seeking from an appropriate provider was not statistically significant (OR = 1.50, 95% CI: 0.88-2.54) between intervention and comparison districts and coverage of appropriate treatment increased in both study groups for all three illnesses. However, the presence of community health volunteers was associated with a 105% increase in appropriate treatment for pneumonia (OR = 2.05, 95% CI: 1.22-3.42) and a 55% drop in traditional treatment for diarrhoea (OR = 0.45, 95% CI: 0.21-0.96). Community health volunteers were also associated with fewer facility treatments for malaria (OR = 0.21, 95% CI: 0.07-0.62). CONCLUSION: After implementing free care, coverage for treatment for all three illnesses in both study groups improved. Deployment of community health volunteers was associated with a reduced treatment burden at facilities and less reliance on traditional treatments.

Service delivery and coverage in primary healthcare in a community-health project in Ibadan, Nigeria.

BACKGROUND: Standard health-service delivery aimed toward improving maternal and child health status remains elusive in Nigeria because of inaccuracies in data documentation leading to a lack of relatively stable evidence. OBJECTIVES: Through a community-health project, this study tested the accuracy of record keeping in primary healthcare services in nine clinics run in Ibadan, Nigeria. METHODS: A validation exercise was performed through a sample of the 10 most recent names extracted from three registers maintained by each clinic. RESULTS: A review of the register covering a period of four years showed a steady increase in: fully-immunised children, registration for antenatal care during the first trimester of pregnancy, the number of women who attended antenatal care at least three times, the overall number of women who booked for antenatal care and women who delivered in Eniosa Community-Health Project facilities over the four-year period. It was possible to trace 86% of those selected from the antenatal care register, 88.9% of those from the birth register and 81.1%of those from the immunisation register. Four women who should have been included for antenatal care, seven who had delivered (but were not in the register) and 13 who reportedly received immunisation but were not listed were found during the validation exercise. CONCLUSION: This study concludes that the names appearing in the register are likely to represent valid events, but that the registers did not capture all such events in the community.

Characteristics of Nigerian women taking sulfadoxine/pyrimethamine twice during pregnancy for the prevention of malaria.

OBJECTIVE: To investigate the characteristics of women in Nigeria who are likely to take sulfadoxine/pyrimethamine (SP) as recommended for the prevention of malaria in pregnancy to reduce maternal and child mortality rates. METHODS: A cross-sectional survey of 1380 women was conducted using a structured questionnaire. The women had given birth within 6months prior to the survey and were drawn from 6 local government areas in Nigeria. RESULTS: Several demographic factors-older age bracket, ever attended school, currently living with a partner, ever married, and wealth-were significantly associated with compliance. Compliance was higher among respondents who had ever been married than among those who had never been married (χ(2)=6.733; P=0.006). Compliance was also higher among those in paid employment (χ(2)=17.110; P<0.001) and those in a higher wealth quintile (χ(2)=34.861; P<0.001). Knowledge of malaria, which included prevention of malaria in pregnancy through use of IPTp with 2 doses of SP, showed a positive association with compliance. Compliance with 2 doses of SP among those with good knowledge was higher (63.9%) than among those with poor knowledge (46.9%) (χ(2)=26.981; P<0.001). CONCLUSION: The present findings could help in targeting health education programs to specific subgroups of women to increase compliance with the recommended 2 doses of SP for the prevention of malaria in pregnancy.

Characteristics of persons who complied with and failed to comply with annual ivermectin treatment.

OBJECTIVE: To assess individual compliance with annual ivermectin treatment in onchocerciasis-endemic villages. METHODS: Multi-site study in eight APOC-sponsored projects in Cameroon, Nigeria and Uganda to identify the socio-demographic correlates of compliance with ivermectin treatment. A structured questionnaire was administered on 2305 persons aged 10 years and above. Two categories of respondents were purposively selected to obtain both high and low compliers: people who took ivermectin 6-8 times and 0-2 times previously. Simple descriptive statistics were employed in characterizing the respondents into high and low compliers, while some socio-demographic and key perceptual factors were employed in regression models constructed to explain levels of compliance among the respondents. RESULTS: Some demographic and perceptual factors associated with compliance were identified. Compliance was more common among men (54.4%) (P < 0.001). Adults (54.6%) had greater rates of high compliance (P < 0.001. The mean age of high compliers (41.5 years) was significantly older (35.8 years) (t = 8.46, P < 0.001). Perception of onchocerciasis and effectiveness of ivermectin influenced compliance. 81.4% of respondents saw benefits in annual ivermectin treatment, high compliance among those who saw benefits was 59.3% compared to 13.3% of those who did not (P < 0.001). CONCLUSION: Efforts to increase compliance with ivermectin treatment should focus on providing health education to youth and women. Health education should also highlight the benefits of taking ivermectin.

Intention to continue with ivermectin treatment for onchocerciasis control after eight years of annual distribution in Cameroon, Nigeria, and Uganda.

This study identified the socio-demographic correlates of intention to comply with ivermectin treatment, from a structured interview of 2,306 persons aged 10 years and above, grouped into high and low compliers, who took ivermectin 6-8 times and 0-2 times respectively. Simple descriptive statistics were employed in characterizing the respondents into high and low compliers, while some socio-demographic and key perceptual factors were employed in regression models constructed to explain levels of compliance among the respondents. Demographic and perceptual factors associated with intention to comply with prolonged treatment with ivermectin were identified. Intention to comply was higher among married persons (91.8%, p < 0.001); local populations (89.8%, p < 0.001); and those with history of complying with treatment (98.2%, p < 0.001). Perception of onchocerciasis and effectiveness of ivermectin influenced intention to continue. The perceptual factors that drive the intention to comply should inform plans for health education at the project and village levels.
