Economic evaluation of Health Extension Program packages in Ethiopia

Financial burden of tuberculosis diagnosis and treatment for patients in Ethiopia: a systematic review and meta-analysis

BACKGROUND

Despite the diagnosis and treatment of tuberculosis (TB) given free of charge in many high-burden countries, the costs that patients face in the cascade of care remain a major concern. Here, we aimed to investigate the financial burden of TB diagnosis and treatment for people with TB in Ethiopia.

METHOD

For this systematic review and meta-analysis, we searched PubMed/MEDLINE, Embase, and Cochrane Center for Clinical Trials from December 1 2022 to 31 June 2023 for articles reporting the cost of diagnosis and treatment for patients regardless of their age with all forms of TB in Ethiopia. Major study outcomes were catastrophic costs, direct (out-of-pocket) pre-diagnosis, medical cost, and post-diagnosis costs, indirect (income loss) costs, coping costs, and total costs. We have used a threshold of 20% to define catastrophic costs. We used random-effects meta-analyses to calculate summary estimates of costs. R-studio software was used for analysis. The study is registered with PROSPERO: CRD42023387687.

RESULT

Twelve studies, with a total of 4792 patients with TB, were included in our analysis. At the 20% threshold of total expenses, 51% of patients (2301 participants from 5 studies, 95% CI: 36-65%, I2 = 97%) faced catastrophic costs due to bacteriologically confirmed drug-sensitive pulmonary TB. Private facility diagnosis, drug-resistance TB, TB-HIV co-infection, hospitalization, and occupation were found to be associated with catastrophic costs. Reduction in the total cost spent by the patients was associated with digital adherence interventions, community-based direct observed therapy, short-course MDR-TB treatment regimens, and active case-finding. Pre-diagnosis costs had a positive correlation with diagnosis delays and the number of facilities visited until diagnosis. Post-diagnosis costs had a positive correlation with rural residence and inpatient treatments.

CONCLUSION

Irrespective of a national policy of free TB service, more than half of TB patients are suffering catastrophic costs due to drug-sensitive pulmonary TB in Ethiopia and most of the patients spend a lot of money during the pre-diagnosis period and intensive phase, but declined drastically over time. Active case-finding, digital adherence interventions, community-based treatment, and comprehensive health insurance coverage have the potential to minimize the financial burden of TB diagnosis and treatment.

Characteristics and Quality Appraisal of the Economic Evaluations Done in Ethiopia: A Systematic Review

BACKGROUND

Health economic evaluation identifies, measures, values, and compares alternative strategies to efficiently allocate scarce resources. The validity, methodological quality, and generalizability of economic evaluations must be assessed, as poorly designed studies can lead to incorrect conclusions. Therefore, this study aimed to evaluate the quality and characteristics of published economic evaluations done in Ethiopia, using the Quality of Health Economics Studies (QHES) and Consolidated Health Economic Evaluation Reporting Standards (CHEERS) instruments.

METHODOLOGY

Various electronic databases were searched using different keywords. We included only original studies conducted in Ethiopia that evaluated the cost and consequences of at least two health interventions. Abstracts, treatment guidelines, reviews, expert opinions, and studies that included other countries were excluded. Two reviewers independently evaluated each study using the QHES and CHEERS instruments and any disagreements were then resolved by a third reviewer.

RESULT

The study included 21 studies published between 2002 and 2021. HIV was the most frequently evaluated medical condition, examined in four (19.06%) of the 21 studies. Seventeen of the studies (80.95%) compared healthcare services or programs, while the other four examined pharmaceutical products. Cost-utility analysis was the economic evaluation technique used in 14 studies (66.67%). Of the studies that disclosed their funding sources, foreign institutions were involved in funding 71.43% of them. Disability-adjusted life-year (DALY) was an outcome metric used in nine (42.86%) studies. The average QHES score of the studies was 82%. Fourteen studies had QHES scores of ≥75% and two had scores of <50%. The studies evaluated using the CHEERS instrument ranged in quality from 42.9% to 92.9%, with an average of 78.23%.

CONCLUSION

Our study revealed that Ethiopia lacks health economic evaluations, particularly on non-communicable diseases. This indicates that the economic evaluation of healthcare interventions in Ethiopia is still in its early stages. Additionally, Ethiopian institutions have played a very limited role in funding research, highlighting the importance of active participation from local institutions.

National Assessment of the Health Extension Program in Ethiopia: Study Protocol and Key Outputs

Background

The Health Extension Program (HEP) was introduced in 2003 to extend primary health care services by institutionalizing the former volunteer-based village health services. However, this program is not comprehensively evaluated.

Materials and Methods

The 2019 comprehensive national assessment of HEP involved (1) assessment through quantitative and qualitative primary data, (2) a thorough systematic review of the HEP literature, and (3) a synthesis of evidence from the two sources. The assessment included household survey(n=7122), a survey of health extension workers (HEWs) (n=584)_, and an assessment of health posts (HPs)(n=343) and their supervising health centers (HCs)(n=179) from 62 randomly selected woredas. As part of the comprehensive assessment.

Output and Results

The outputs were (a) full and abridged reports, (b) 40 posters, (c) seven published, three under review scientific papers and (d) seven papers in this special issue. During the one-year period preceding the study, 54.8% of women, 32.1% of men, and 21.9% of female youths had at least a one-time interaction with HEWs. HPs and HEWs were universally available. There were critical gaps in the skills and motivation of HEWs and fulfillment of HP standards: 57.3% of HEWs were certified, average satisfaction score of HEWs was 48.6%, and 5.4% of HPs fulfilled equipment standards.

Conclusions

The findings informed policy and program decisions of the Ministry of Health, including the design of the HEP Optimization Roadmap 2020-2035 and the development Health Sector Transformation Plan II. It is also shared with global community through published papers.

Learning from success cases: ecological analysis of potential pathways to universal access to family planning care in low- and middle-income countries

Background  Universal access to family planning services is a well-recognized human right and several countries and organizations are committed to this goal. Our objective was to identify countries who improved family planning coverage in the last 40 years and investigate which contexts enabled those advances.  Methods  Analyses were based on data from publicly available national health surveys carried out since 1986 in Egypt, Ethiopia, Rwanda, Afghanistan, Brazil, and Ecuador, selected based on previous evidence. We estimated demand for family planning satisfied with modern methods (mDFPS) for each country and explored inequalities in terms of wealth, women's education, and women's age. We also explored contextual differences in terms of women's empowerment, percentage of population living in extreme poverty, and share of each type of contraceptive. To better understand political and sociocultural contexts, country case studies were included, based on literature review.  Results  Patterns of mDFPS increase were distinct in the selected countries. Current level of mDFPS coverage ranged between 94% in Brazil and 38% in Afghanistan. All countries experienced an important reduction in both gender inequality and extreme poverty. According to the share of each type of contraceptive, most countries presented higher use of short-acting reversible methods. Exceptions were Ecuador, where the most used method is sterilization, and Egypt, which presented higher use of long-acting reversible methods. In the first years analyzed, all countries presented huge gaps in coverage according to wealth, women's education and women's age. All countries managed to increase coverage over recent years, especially among women from the more disadvantaged groups.  Conclusions  Family planning coverage increased along with reductions in poverty and gender inequality, with substantial increases in coverage among the most disadvantaged in recent years. Policies involving primary health care services, provision of various methods, and high quality training of health providers are crucial to increase coverage.

Implementing and Evaluating Community Health Worker-Led Cardiovascular Disease Risk Screening Intervention in Sub-Saharan Africa Communities: A Participatory Implementation Research Protocol

The increasing burden of non-communicable diseases (NCDs), particularly cardiovascular diseases (CVD) in low- and middle-income countries (LMICs) poses a considerable threat to public health. Community-driven CVD risk screening, referral and follow-up of those at high CVDs risk is essential to supporting early identification, treatment and secondary prevention of cardiovascular events such as stroke and myocardial infarction. This protocol describes a multi-country study that aims to implement and evaluate a community health worker (CHW)-led CVD risk screening programme to enhance referral linkages within the local primary care systems in sub-Saharan Africa (SSA), using a participatory implementation science approach. The study builds upon a prior community-driven multicentre study conducted by the Collaboration for Evidence-based Health Care and Public Health in Africa (CEBHA+). This is a participatory implementation research. The study will leverage on the CVD risk citizen science pilot studies conducted in the four selected CEBHA+ project countries (viz. Ethiopia, Rwanda, Malawi, and South Africa). Through planned engagements with communities and health system stakeholders, CHWs and lay health worker volunteers will be recruited and trained to screen and identify persons that are at high risk of CVD, provide referral services, and follow-up at designated community health clinics. In each country, we will use a multi-stage random sampling to select and then screen 1000 study participants aged 35-70 years from two communities (one rural and one urban). Screening will be done using a simple validated non-laboratory-based CVD risk assessment mobile application. The RE-AIM model will be used in evaluating the project implementation outcomes, including reach, fidelity, adoption and perceived effectiveness. Developing the capacities of CHWs and lay health worker volunteers in SSA to support population-based, non-invasive population-based CVD risk prevention has the potential to impact on early identification, treatment and secondary prevention of CVDs in often under-resourced communities. Using a participatory research approach to implementing mobile phone-based CHW-led CVD risk screening, referral and follow-up in SSA will provide the evidence needed to determine the effectiveness of CVD risk screening and the potential for scaling up in the wider region.

Disparities in the implementation of the Health Extension Program in Ethiopia: Doing more and better towards universal health coverage

Introduction

Large-scale implementation of the Health Extension Program (HEP) has enabled Ethiopia to make significant progress in health services coverage and health outcomes. However, evidence on equity and disparities in the implementation of the HEP is limited. The aim of this study was to examine disparities in the implementation of the HEP in Ethiopia.

Methods

We used data from the 2019 National HEP assessment which was conducted between Oct 2018 and Sept 2019 in nine regions in the country. Data were collected from 62 districts, 343 Health posts, 179 Health centres, 584 Health Extension Workers (HEWs), and 7043 women from 7122 Households. This study focused on selected input, service delivery, and coverage indicators. We used rate differences, rate ratios and index of disparity to assess disparities in HEP implementation across regions.

Results

We found wide inter-regional disparities in HEP implementation. Developing regional states (DRS) had significantly lower availability of qualified HEWs (Rate Ratio (RR) = 0.54), proportion of households visited by Health Extension workers (RR = 0.40), and proportion of mothers who received education on child nutrition (RR = 0.45) as compared national average. There were also significant disparities in HEP implementation among DRS in the proportion of households visited by HEWs in the past 12 months (Index of disparity = 1.58) and proportion of adolescents who interacted with HEWs (Index of disparity = 1.43). Despite low overall coverage of health services in DRS, the contribution of the HEP for maternal health services was relatively high.

Conclusion

There were significant inter-regional disparities in the implementation HEP in Ethiopia. The level of disparity among DRS was also remarkable. To achieve Universal Health Coverage, it is important that these disparities are addressed systematically and strategically. We recommend a tailored approach in HEP implementation in DRS.

What are the mechanisms and contexts by which care groups achieve social and behavioural change in low- and middle-income countries? Group motivation findings from a realist synthesis

OBJECTIVE

Infant and under-five mortality rates in low- and middle-income countries (LMIC) can be reduced by encouraging behaviours such as sleeping under insecticide-treated bed nets, exclusive breast-feeding for the first 6 months, regular handwashing, etc. Community-based volunteer or peer-to-peer mechanisms are cost-effective ways of promoting these lifesaving practices. However, the sustainability and reach of community-based behaviour change promotion remains a challenge. Our inquiry focuses on the utilisation, by non-governmental organisations (NGO), of Care Groups, a peer-to-peer behaviour change intervention. We asked: What are the mechanisms and contexts by which Care Groups achieve social and behavioural change in nutrition, health and other sectors?

DESIGN

Realist synthesis reviewing forty-two texts that contained empirical evidence about Care Group interventions.

SETTING

LMIC.

PARTICIPANTS

We held consultations with a research reference group, which included Care Group and nutrition experts, and Care Group - implementing NGO staff in Malawi.

RESULTS

Different types of motivation drive the establishment and the sustainability of peer group interventions. A certain amount of motivation was derived from the resources provided by the NGO establishing the Care Groups. Subsequently, both volunteers and neighbourhood group members were motivated by the group dynamics and mutual support, as well as support from the wider community. Finally, volunteers and group members alike became self-motivated by their experience of being involved in group activities.

CONCLUSIONS

When designing and implementing community-based behaviour change interventions, awareness of the multi-directional nature of the motivating drivers that are experienced by peer- or community group members is important, to optimise these groups' reach and sustainability.

Exploring complementary and competitive relations between non-communicable disease services and other health extension programme services in Ethiopia: a multilevel analysis

Background

Ethiopia has recently revitalised its health extension programme (HEP) to address the rising burden of non-communicable diseases (NCDs). We examined the effects of existing essential HEP services on the uptake of NCD preventive services.

Methods

We applied a mixed-effect non-linear model with a logit link function to identify factors associated with a community resident’s probability of receiving NCD prevention services through the HEP. The data were drawn from the Ethiopian HEP assessment Survey conducted in all regions. The analysis included 9680 community residents, 261 health extension workers (HEWs), 153 health posts, 119 health centres, 55 districts and 9 regions, which we combined hierarchically into a single database.

Results

In the 12 months before the survey, 22% of the sample population reported receiving NCD preventive service at least once. The probability of receiving NCD prevention service increased by up to 25% (OR=1.25, CI 1.01 to 1.53) if health centres routinely gathered NCD data from health posts and by up to 48% (OR=.48, CI 1.24 to 1.78) if they provided general (ie, non-NCD specific) training to HEWs. NCD preventive service uptake also increased if the HEW held level IV qualification (OR=1.32, CI 1.06 to 1.65) and lived in the community (OR=1.24, CI 1.03 to 1.49). Conversely, if facilities delayed general performance reviews of HEWs by a month, uptake of NCD prevention services decreased by 6% (OR=0.94, CI 0.91 to 0.97). We observed that better HIV/AIDS programme performance was associated with a lower uptake of NCD preventive services (OR=0.15, CI 0.03 to 0.85).

Conclusion

Despite efforts to improve NCD services through the HEP, the coverage remains limited. A strong HEP is good for the uptake of NCD preventive services. However, integration requires a careful balance, so that the success already recorded for some existing programmes is not lost.

A Systematic Review of Scope and Quality of Health Economic Evaluations Conducted in Ethiopia

There has been an increased interest in health technology assessment and economic evaluations for health policy in Ethiopia over the last few years. In this systematic review, we examined the scope and quality of healthcare economic evaluation studies in Ethiopia. We searched seven electronic databases (PubMed/MEDLINE, EMBASE, PsycINFO, CINHAL, Econlit, York CRD databases and CEA Tufts) from inception to May 2021 to identify published full health economic evaluations of a health-related intervention or programme in Ethiopia. This was supplemented with forward and backward citation searches of included articles, manual search of key government websites, the Disease Control Priorities-Ethiopia project and WHO-CHOICE programme. The quality of reporting of economic evaluations was assessed using the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist. The extracted data were grouped into subcategories based on the subject of the economic evaluation, organized into tables and reported narratively. This review identified 34 full economic evaluations conducted between 2009 and 2021. Around 14 (41%) of studies focussed on health service delivery, 8 (24%) on pharmaceuticals, vaccines and devices, and 4 (12%) on public-health programmes. The interventions were mostly preventive in nature and focussed on communicable diseases (n = 19; 56%) and maternal and child health (n = 6; 18%). Cost-effectiveness ratios varied widely from cost-saving to more than US $37 313 per life saved depending on the setting, perspectives, types of interventions and disease conditions. While the overall quality of included studies was judged as moderate (meeting 69% of CHEERS checklist), only four out of 27 cost-effectiveness studies characterized heterogeneity. There is a need for building local technical capacity to enhance the design, conduct and reporting of health economic evaluations in Ethiopia.

Determinants of stillbirth among reviewed perinatal deaths in Ethiopia

BACKGROUND

The global burden of stillbirth has declined over time. However, the problem is still prominent in South Asian and Sub-Saharan African countries. Ethiopia is one of the top stillbirth-reporting countries worldwide. Despite several measures taken to reduce the burden of stillbirth; the pace of decline was not as good as the post-neonatal death. Thus, this study is aimed at identifying potential factors related to stillbirth in Ethiopia based on nationally reviewed perinatal deaths.

METHOD

The national perinatal death surveillance data were used for this study. A total of 3,814 reviewed perinatal death were included in the study. Two model families,namely generalized estimating equation, and alternating logistic regression models from marginal model family were employed to investigate the risk factors of stillbirth. The alternating logistic regression model was selected as the best fit for the final analysis.

RESULT

Among reviewed perinatal deaths nearly forty percent (37.4%) were stillbirths. The findings from the multivariate analysis demonstrated that the place of birth (in transit and at home), cause of death (infection, and congenital and chromosomal abnormalities), maternal health condition (women with complications of pregnancy, placenta, and cord), delay one (delay in deciding to seek care) and delay three (delay in receiving adequate care) were associated with an increased risk of having a stillbirth. On the other hand, maternal education (women with primary and above education level) and the type of health facility (women who were treated in secondary and tertiary health care) were associated with a decreased risk of having a stillbirth.

CONCLUSION

The study identified that both individual (place of delivery, cause of death, maternal health condition, maternal education, and delay one) and facility level (type of health facility and delay three) factors contributed to stillbirth outcome. Therefore, policies that are aimed at encouraging institutional delivery, improving health seeking behavior, and strengthening facility-level readiness should be devised to reduce the high burden of stillbirth in Ethiopia.

Community health extension workers' training and supervision in Ethiopia: Exploring impact and implementation challenges for non-communicable disease service delivery

Training and supervision of health workers are critical components of any health system;thus, we assessed how they impact health extension workers' (HEWs) role in non-communicable disease (NCD) service delivery in Ethiopia's health extension program (HEP), using an in-depth qualitative study conducted in 2019.The study covered two regions-the Tigray and the South Nations, Nationalities and Peoples Region (SNNPR)-and involved the Federal Ministry of Health. We conducted twenty-seven key informant interviews with federal and regional policymakers, district health officials, health centre representatives and HEWs.Participants highlighted substantial implementation challenges with training and supervision practices delivered via the HEP. Training for NCDs lacked breadth and depth. IT was described as inconsistently delivered with variable availability within and between regions;and when available, the quality was low with scant content specific to NCDs. HEP supervision was inconsistent and, rather than being supportive, mainly focused on finding faults in HEW work practices. Supervisors themselves had skill gaps in critical areas overall, and specifically concerning NCDs. HEWs' performance appraisal encompassed too many indicators, leading to excessive complexity, which was burdensome to HEWs. This, negatively impacted HEW motivation and compromised service delivery. HEW involvement in non-HEP activities (such as promoting other government programs) often competed with their core mandates, thus affecting HEP service delivery.Efforts to address training and supervision constraints in Ethiopia's HEP should focus on improving the quality of NCD training for HEWs and supervisors, shifting from authoritative to supportive supervision, simplifying performance appraisal and reducing competing attention from other programs.

Health extension workers' perceived health system context and health post preparedness to provide services: a cross-sectional study in four Ethiopian regions

OBJECTIVE

The health system context influences the implementation of evidence-based practices and quality of healthcare services. Ethiopia aims at reaching universal health coverage but faces low primary care utilisation and substandard quality of care. We assessed the health extension workers' perceived context and the preparedness of health posts to provide services.

SETTING

This study was part of evaluating a complex intervention in 52 districts of four regions of Ethiopia. This paper used the endline data collected from December 2018 to February 2019.

PARTICIPANTS

A total of 152 health posts and health extension workers serving selected enumeration areas were included.

OUTCOME MEASURES

We used the Context Assessment for Community Health (COACH) tool and the Service Availability and Readiness Assessment tool.

RESULTS

Internal reliability of COACH was satisfactory. The dimensions community engagement, work culture, commitment to work and leadership all scored high (mean 3.75-4.01 on a 1-5 scale), while organisational resources, sources of knowledge and informal payments scored low (1.78-2.71). The general service readiness index was 59%. On average, 67% of the health posts had basic amenities to provide services, 81% had basic equipment, 42% had standard precautions for infection prevention, 47% had test capacity for malaria and 58% had essential medicines.

CONCLUSION

The health extension workers had a good relationship with the local community, used data for planning, were highly committed to their work with positive perceptions of their work culture, a relatively positive attitude regarding their leaders, and reported no corruption or informal payments. In contrast, they had insufficient sources of information and a severe lack of resources. The health post preparedness confirmed the low level of resources and preparedness for services. These findings suggest a significant potential contribution by health extension workers to Ethiopia's primary healthcare, provided that they receive improved support, including new information and essential resources.
