Differences in Role and Support Between Volunteer and Paid Community Health Workers in the State of Nebraska.

Despite the growing importance of community health workers (CHWs) in public health, it has been difficult to characterize the roles and scope of services for this workforce in part because of the variability in the employment status of CHWs, ranging from full-time, part-time, to volunteer. Based on analysis of survey data from a statewide assessment of the CHW workforce in Nebraska (n = 142) conducted between 2019 and 2020, the proportions of CHWs who worked full-time, part-time, or volunteer were respectively 64%, 12%, and 21%. Over three quarters (76.7%) of volunteer CHWs were primarily working with Hispanic communities, as compared to less than 30% among full-time and part-time CHWs. About 80% of volunteer CHWs received training before becoming a CHW, substantially higher than the corresponding proportions among full-time (46.2%) and part-time CHWs (52.9%). In terms of tasks performed, the proportion of volunteer CHWs who provided health screenings (70%) were much higher than full or part-time CHWs (41.8% and 11.8% respectively, p < 0.001); whereas the latter two groups were significantly more likely than volunteer CHWs to provide other tasks such as coordinating care, health coaching, social support, transportation, interpretation, data collection, advocacy, and cultural awareness. Volunteer CHWs may hold potential for serving non-Hispanic communities. Future development of the CHW workforce can benefit from understanding and leveraging the significant differences in roles and scope of services among CHWs with various employment statuses.

Effectiveness of community case management of malaria on severe malaria and inpatient malaria deaths in Zambia: a dose–response study using routine health information system data

BackgroundCommunity case management of malaria (CCM) has been expanded in many settings, but there are limited data describing the impact of these services in routine implementation settings or at large scale. Zambia has intensively expanded CCM since 2013, whereby trained volunteer community health workers (CHW) use rapid diagnostic tests and artemether-lumefantrine to diagnose and treat uncomplicated malaria.MethodsThis retrospective, observational study explored associations between changing malaria service point (health facility or CHW) density per 1000 people and severe malaria admissions or malaria inpatient deaths by district and month in a dose–response approach, using existing routine and programmatic data. Negative binomial generalized linear mixed-effect models were used to assess the impact of increasing one additional malaria service point per 1000 population, and of achieving Zambia’s interim target of 1 service point per 750 population. Access to insecticide-treated nets, indoor-residual spraying, and rainfall anomaly were included in models to reduce potential confounding.ResultsThe study captured 310,855 malaria admissions and 7158 inpatient malaria deaths over 83 districts (seven provinces) from January 2015 to May 2020. Total CHWs increased from 43 to 4503 during the study period, while health facilities increased from 1263 to 1765. After accounting for covariates, an increase of one malaria service point per 1000 was associated with a 19% reduction in severe malaria admissions among children under five (incidence rate ratio [IRR] 0.81, 95% confidence interval [CI] 0.75–0.87, p < 0.001) and 23% reduction in malaria deaths among under-fives (IRR 0.77, 95% CI 0.66–0.91). After categorizing the exposure of population per malaria service point, there was evidence for an effect on malaria admissions and inpatient malaria deaths among children under five only when reaching the target of one malaria service point per 750 population.ConclusionsCCM is an effective strategy for preventing severe malaria and deaths in areas such as Zambia where malaria diagnosis and treatment access remains challenging. These results support the continued investment in CCM scale-up in similar settings, to improve access to malaria diagnosis and treatment.

Does inter-border conflict influence the views of task sharing among community health volunteers in Nigeria? A qualitative study

BackgroundVolunteer community health workers are increasingly being engaged in Nigeria, through the World Health Organization’s task sharing strategy. This strategy aims to address gaps in human resources for health, including inequitable distribution of health workers. Recent conflicts in rural and fragile border communities in northcentral Nigeria create challenges for volunteer community health workers to meet their community's increasing health needs. This study aimed to explore the perception of volunteers involved in task sharing to understand factors affecting performance and delivery in such contexts.MethodsThis was a qualitative study conducted in fragile border communities in north central Nigeria. Eighteen audio recorded, semi-structured interviews with volunteers and supervisors were performed. Their perceptions on how task sharing and allocation of tasks affect performance and delivery were elucidated. The transactional social framework was applied during the thematic analysis process to generate an explanatory account of the research data, which was analysed using NVivo software.ResultsPromotive and preventive tasks were shared among the predominantly agrarian respondents. There was a structured task allocation process that linked the community with the health system and mainly cordial relationships were in place. However, there were barriers related to ethnoreligious crises and current conflict, timing of task allocations, gender inequities in volunteerism, shortage of commodities, inadequate incentives, dwindling community support and negative attitudes of some volunteers.ConclusionThe perception of task sharing was mainly positive, despite the challenges, especially the current conflict. In this fragile context, reconsideration of non-seasonal task allocations within improved community-driven selection and security systems should be encouraged. Supportive supervision and providing adequate and timely renumeration will also be beneficial in this fragile setting.

The fear of social stigma experienced by men: a barrier to male involvement in antenatal care in Misungwi District, rural Tanzania

BackgroundEvidence has shown that male involvement is associated with improved maternal health outcomes. In rural Tanzania, men are the main decision makers and may determine women’s access to health services and ultimately their health outcomes. Despite efforts geared towards enhancing male participation in maternal health care, their involvement in antenatal care (ANC) remains low. One barrier that impacts men’s participation is the fear and experience of social stigma. This study, builds on previous findings about men’s perspectives in attending antenatal care appointments in Misungwi district in Tanzania, examining more closely the fear of social stigma amongst men attending ANC together with their partners.MethodsTwelve individual interviews and five focus group discussions were conducted using semi-structured questionnaires with fathers and expectant fathers. In-depth interviews were conducted with health providers, volunteer community health workers and village leaders. Interviews were audiotaped, and transcripts were transcribed and translated to English. Transcripts were organized in NVivo V.12 then analyzed using thematic approach.ResultsThree main themes were found to create fear of social stigma for men: 1. Fear of HIV testing; 2. Traditional Gender Norms and 3. Insecurity about family social and economic status.ConclusionRespondent’s experiences reveal that fear of social stigma is a major barrier to attend ANC services with their partners. Attention must be given to the complex sociocultural norms and social context that underly this issue at the community level. Strategies to address fear of social stigma require an understanding of the real reasons some men do not attend ANC and require community engagement of community health workers (CHWs), government officials and other stakeholders who understand the local context.

Five-year retention of volunteer community health workers in rural Uganda: a population-based retrospective cohort.

Community health workers (CHWs) effectively improve maternal, newborn and child health (MNCH) outcomes in low-to-middle-income countries. However, CHW retention remains a challenge. This retrospective registry analysis evaluated medium-term retention of volunteer CHWs in two rural Ugandan districts, trained during a district-wide MNCH initiative. From 2012 to 2014, the Healthy Child Uganda partnership facilitated district-led CHW programme scale-up. CHW retention was tracked prospectively from the start of the intervention up to 2 years. Additional follow-up occurred at 5 years to confirm retention status. Database analysis assessed CHW demographic characteristics, retention rates and exit reasons 5 years post-intervention. A multivariable logistic regression model examined 5-year retention-associated characteristics. Of the original cohort of 2317 CHWs, 70% were female. The mean age was 38.8 years (standard deviation, SD: 10.0). Sixty months (5 years) after the start of the intervention, 84% of CHWs remained active. Of those exiting (n = 377), 63% reported a ‘logistical’ reason, such as relocation (n = 96), new job (n = 51) or death (n = 30). Sex [male, female; odds ratio (OR) = 1.53; 95% confidence interval (CI): 1 · 20–1 · 96] and age group (<25 years, 30–59; OR = 0.40; 95% CI: 0.25–0.62) were significantly associated with 5-year retention in multivariable modelling. Education completion (secondary school, primary) was not significantly associated with retention in adjusted analyses. CHWs in this relatively large cohort, trained and supervised within a national CHW programme and district-wide MNCH initiative, were retained over the medium term. Importantly, high 5-year retention in this intervention counters findings from other studies suggesting low retention in government-led and volunteer CHW programmes. Encouragingly, findings from our study suggest that retention was high, not significantly associated with timing of external partner support and largely not attributed to the CHW role i.e. workload and programme factors. Our study showcases the potential for sustainable volunteer CHW programming at scale and can inform planners and policymakers considering programme design, including selection and replacement planning for CHW networks.

83 Understanding complex community structures to improve sexual reproductive health for adolescents in Uganda

Primary Subject areaGlobal Child and Youth HealthBackgroundBased on the 2014 census, 35% of Uganda’s population is between 10-24 years old. Health indicators show concerning sexual and reproductive health (SRH) trends such as high teen pregnancy, unsafe abortions, limited contraceptive use, and access to antenatal and postnatal care. However, the barriers to adolescents seeking and receiving care are complicated due to pre-existing social structures in smaller, closely linked communities.ObjectivesTo understand the social structures and motivation of communities in western Ugandan districts that impact SRH in adolescents to better implement Healthy Adolescent and Young people (HAY!).Design/MethodsIn September 2020, a qualitative study was conducted in 2 districts, in southwestern Uganda. Fourteen focus group discussions and 3 key informant interviews consisted of 94 participants were carried out with a purposive sample of adolescents, parents, community health workers (CHWs), community leaders, health facility staff, and district health officers. Ethics approval was obtained and COVID-19 prevention guidelines were strictly followed. Data was audio-recorded, transcribed, and thematically analyzed.ResultsBased on our qualitative inquiry, participants recognized that adolescents face numerous SRH challenges and expressed their tension for change and motivation to support interventions that may positively impact SRH behavior and outcomes in adolescents. However, participants who were mothers highlighted that their motivation was due to better marriage prospects for their daughters, which is determined by respect and social standing in the community. In situations of unwanted pregnancies, participants shared that because of the fear of shame, and desire to keep adolescents in school, mothers often supported unsafe abortion to maintain community standing. This is an unusual and interesting finding. Similarly, aunties and uncles were traditionally regarded as champions for protecting and guiding adolescents, but participants highlighted a negative shift in this dynamic; aunties and uncles put female adolescents at risk by connecting them with interested men in exchange for gifts and money. Consequently, they are no longer trusted. Despite these gaps, volunteer CHWs who work closely within their communities by conducting home visits, educating, and providing referrals, emerged as a trusted resource by adolescent participants in accessing SRH related information. CHW participants also shared that adolescents often confided in them when unable to speak openly with their parents.ConclusionAlthough participant groups were motivated towards supporting adolescents, interventions must first understand and navigate complex community structures to deliver a comprehensive and targeted intervention to improve SRH outcomes in adolescents.

Patient perspectives on the helpfulness of a community health worker program for HIV care engagement in Tanzania

ABSTRACT Task-shifting is a valuable approach for redistributing clinical tasks to nonprofessional health workers and relieving human resource shortages. The Community-Based HIV Services (CBHS) program is a national cohort of volunteer community health workers (CHWs) who support HIV care engagement at clinics in Tanzania. We recruited 23 patients initiating HIV care at two clinics to understand their experiences with the CBHS program. Participants completed qualitative interviews by telephone discussing the perceived helpfulness of the program, their level of connection with CHWs, and suggestions for improvement. Data were analyzed through an inductive, team-based qualitative approach. Most participants found the program to be helpful and described close, positive connections. CHWs offered education, emotional support to accept one’s diagnosis and cope with stigma, and encouragement to remain engaged in HIV care. However, several participants described minimal, shallow contact with CHWs, and felt the program did not benefit their HIV care. Participants recommended increasing CHW efforts to engage people living with HIV (PLWH) in the broader community, and addressing socioeconomic barriers to care engagement. When contacts are consistent, the CBHS program is a strong resource for PLWH. To maximize the potential of the program, administrators should enhance oversight and extend new training opportunities for CHWs.

Community acceptance, satisfaction, and support for case management of malaria of various degrees in selected rural communities in Ibadan, Oyo-State.

This study aimed to assess communities' perception and adoption of the evidenced-based malaria diagnosis and case management intervention targeted at under-five children. The effectiveness of trained Volunteer Community Health Workers (VCHWs) to diagnose malaria among under-five children using rapid diagnostic testing kit, provide treatment using Artemisinin Combination Therapy and rectal Artesunate were assessed. A qualitative evaluation study was conducted in October 2015. Communities in the 6 rural wards in Ona-Ara Local Government Area, Oyo State Nigeria. Caregivers of under-five children, community-based frontline health workers, and community leaders selected using purposively sampling. Nine Focus Group Discussions and 15 Key Informant Interviews were conducted using a pre-tested guide. Data were subjected to thematic analysis. It was disclosed that VCHWs promoted people's access to prompt and appropriate malaria treatment. The communities accepted the VCHWs; the reasons given for this included the following: effectiveness of VCHWs in case management of malaria; good inter-personal relationship with caregivers; and the positive health outcomes associated with services provided by them. In addition, community members expressed satisfaction with the VCHWs and provided them with all the support needed to function throughout the malaria case management intervention. The VCHWs considered the support as a great source of encouragement. The use of VCHWs to treat malaria was adjudged to be effective and considered acceptable to the communities. The adoption of the intervention and its integration into the primary health system by the government is advocated for in medically underserved rural communities. This work was supported by UNICEF/UNDP/World Bank/WHO Special Programme for Research & Training in Tropical Diseases, World Health Organization, Geneva, Switzerland (project ID: A80550 [Nigeria] through funds made available by the European Commission (FP7) for research to improve community access to health interventions in Africa.

Exploring supervision for volunteer community health workers in Mukono District, Uganda: An exploratory mixed-methods study

ABSTRACT Community Health Worker (CHW) supervision is an under-researched area. This mixed-methods study engaged key stakeholders involved in CHW supervision in Mukono District, Uganda including CHWs (n = 14), District Health Office officials (n = 5), NGO programme managers (n = 3) and facility-based health staff (n = 3). Our study aimed to explore how supervision is currently conceptualised and delivered in this setting, the desired qualities of a potential supervisor, as well as the challenges regarding supervision and potential solutions to address these. To understand these concepts, we conducted structured surveys and individual interviews. Survey data were analysed in SPSS using descriptive statistics. Interview transcripts were thematically analysed in NVivo using conventional content analysis. This study revealed current CHW supervision in this context is fragmented. Supervision is perceived both as a means of motivating CHWs and facilitating ongoing training, as well as a way of holding CHWs accountable for their work. Stakeholders identified technical knowledge and expertise, strong interpersonal skills and cultural awareness as desirable qualities for a supervisor. Challenges surrounding supervision included a shortage of funding, a lack of guidelines on supervision, and infrequent supervision. To address these challenges, stakeholders proposed the need for increased funding, creating clearer job descriptions for supervisors, and in-person supervisory meetings.

The Role of Community Health Workers in HIV Care Engagement: A Qualitative Study of Stakeholder Perspectives in Tanzania.

Suboptimal retention in HIV care is a major driver of the global epidemic, including in sub-Saharan Africa. In Tanzania, the national Community-Based HIV Services program integrates volunteer community health workers (CHWs) to support patient care engagement and reduce the burden placed on HIV clinic nurses; however, few studies have assessed the value of CHWs supporting HIV care. Qualitative interviews were conducted with 48 administrators, nurses, CHWs, and patients to explore strengths and limitations of the Community-Based HIV Services program. Stakeholders believed CHWs are uniquely positioned to establish trust and provide patient support. Patients who had frequent contact with CHWs described them as valued sources of education and encouragement, but fewer than half of the patients interviewed had ever met with a CHW. Clinic nurses described feeling disconnected from CHWs, and stakeholders highlighted the need for financial, logistical, and educational support to rejuvenate the program and effectively address care engagement challenges.

"Even when people live just across the road…they won't go": Community health worker perspectives on incentivized delays to under-five care-seeking in urban slums of Kampala, Uganda.

BackgroundAlthough under-five (U5) mortality in Uganda has dropped over the past two decades, rates in urban slum neighborhoods remain high. As part of a broader verbal and social autopsy study of U5 deaths, this study explored the perspectives of volunteer community health workers, called Village Health Teams (VHTs), on why children under five in Kampala’s informal settlements are still dying despite living in close proximity to nearby health facilities.MethodsThis exploratory, qualitative study took place between January and March 2020 in the Rubaga division of Kampala, Uganda. VHTs from the slums of Kawaala and Nankulabye parishes, both located near a large government health center, were interviewed by a trained local interviewer to determine their perceptions of barriers to care-seeking and attribution for U5 childhood deaths. All interviews were audiotaped, transcribed into English, imported into NVivo V 12.0 and thematically analyzed using the Attride-Stirling framework.Results20 VHTs were interviewed, yielding two global themes, the first focusing on VHTs perceptions of their role in the community to promote positive health outcomes, and the second focusing on VHTs’ perceptions of how prompt care-seeking is disincentivized. Within the latter theme, three inter-related sub-themes emerged: disincentives for care-seeking at the health system level, which can drive negative beliefs held by families about the health system, and in turn, drive incentives for alternative health behaviors, which manifest as “incentivized delays” to care-seeking.DiscussionThis study illustrates VHT perspectives on the complex interactions between health system disincentives and the attitudes and behaviors of families with a sick child, as well as the reinforcing nature of these factors. Findings suggest a need for multi-pronged approaches that sensitize community members, engage community and health system leadership, and hold providers accountable for providing high-quality care. VHTs have enormous potential to foster improvement if given adequate resources, training, and support.

Volunteer Community Health and Agriculture Workers Help Reduce Childhood Malnutrition in Tajikistan.

Childhood malnutrition is a nationally-recognized problem in Tajikistan. In 2017, 6% of children under 5 years were wasted and 18% were stunted. Through the Tajikistan Health and Nutrition Activity (THNA), funded by the U.S. Agency for International Development's Feed the Future, IntraHealth International trained 1,370 volunteer community health workers (CHWs) and 500 community agricultural workers (CAWs) in 500 rural communities to improve nutrition among children and pregnant and breastfeeding women. CHWs and CAWs mutually encourage health behavior change, reinforce better agricultural practices, and promote maternal and child health and nutritious diets through household visits, community events, and peer support groups. CHWs refer children with malnutrition and diarrhea and pregnant women who are not registered for antenatal care to health facilities. THNA supported CHWs/CAWs through peer learning, refresher trainings, supportive supervision, and quarterly material incentives. We observed gains in knowledge, attitudes, and practices across health; nutrition; water, sanitation, and hygiene (WASH); and agriculture in target communities. From 2016 to 2019, we observed statistically significant (P<.05) improvements in children receiving a minimum acceptable diet; children with diarrhea receiving more liquids; women making 4 or more antenatal care visits; women reporting improved WASH; and farmers demonstrating improved agricultural practices. A February 2020 screening of 94.6% of children under 5 years in target communities found the prevalence of children with signs of wasting at 2.2%. Partnerships between CHWs, CAWs, and rural health workers facilitated these results. Paired agricultural and health interventions proved successful in improving nutrition of children and may be applicable in other contexts. Although effective in delivering interventions, CHWs/CAWs experience attrition, need motivation, and require intensive support. Assuming responsibility for this community-based volunteer workforce presents a major challenge for Tajikistan's national and local governments.

Men perspectives on attending antenatal care visits with their pregnant partners in Misungwi district, rural Tanzania: a qualitative study

BackgroundMens’attendance with their pregnant partners at facility-based antenatal care (ANC) visits is important for maternal and child health and gender equality yet remains uncommon in parts of rural Tanzania. This study examined men’s perspectives on attending ANC with their pregnant partners in Misungwi District, Tanzania.MethodsTwelve individual interviews and five focus group discussions were conducted using semi-structured questionnaires with fathers, expectant fathers, and in-depth interviews were done to health providers, volunteer community health workers, and village leaders. Interviews were recorded and transcribed in Swahili and later translated to English. The research team conducted thematic analysis to identify common themes among interviews.ResultsWe identified two broad themes on the barriers to male attendance at facility-based ANC visits: (1) Perceived exclusion during ANC visits among men (2) Traditional gender norms resulting to low attendance among men.ConclusionAttendance at health facility for ANC visits by men with their pregnant partners in the study areas were challenged by structural and local cultural norms. At the facility men were uncomfortable to sit with women due to lack of specific waiting area for men and that they perceived to be neglected. Local cultural norms demanded women to have secrecy in pregnancy while men perceived not to have a role of being with their partners during ANC visits.

65 Mama na Mtoto: Health Outcome Achievements Following Implementation of Comprehensive Maternal Newborn Programming in Rural Tanzania

Abstract Introduction/Background Preventable deaths in pregnant women and newborns remain unacceptably high in East Africa. Limited antenatal, delivery and postnatal care-seeking combined with service delivery gaps at government facilities contribute to high mortality. Between 2016-2019, partners from Tanzania, Uganda, and Canada jointly developed, implemented, and evaluated a comprehensive, district-wide maternal, newborn, and child health (MNCH) ‘package’ in Lake Zone, Tanzania. Known locally as ‘Mama na Mtoto’, the scale-up programming involved training and capacity building for district managers, health facility staff and a network of volunteer community health workers selected by their own communities. Objectives To quantitatively assess changes in MNCH health outcomes following the Mama na Mtoto intervention. Design/Methods MNCH household-level care-seeking outcomes were assessed using a pre/post coverage survey adapted from the Demographic Health Survey. Households and women (15-49 years), selected through cluster sampling (cluster unit=hamlet), were surveyed by local, trained research assistants using tablet-based surveys. MNCH service outcomes were assessed at all government health facilities using a comprehensive pre/post cross-sectional audit tool; key measures included staff, equipment, infrastructure, supplies, and medication availability. Descriptive statistics for antenatal care (ANC), health facility delivery (HFD), and postnatal care (PNC)-related indicators were analyzed pre- and post-intervention using R software. Composite health facility ‘Readiness Scores’ were calculated through tallies of relevant itemized facility-based measures for each core MNCH service area across the district. Absolute percentage differences, confidence intervals and design effect are presented where relevant. Results In total, 1,977 households, 2,438 women, and 45 health facilities were surveyed pre-intervention and 1,835 homes, 2,073 women, and 49 health facilities were surveyed post. Care-seeking indicators with statistically significant changes were ANC 4+ (+11%), ANC &amp;lt;12 weeks (+7%), HFD (+17%), and PNC for mothers (+9%); PNC for babies was not significant. Increases in composite MNCH Service Readiness Scores were as follows: ANC +24%, essential newborn care +42%, newborn resuscitation +37%, and labour and delivery +27%. Conclusion The comprehensive MnM package was associated with important improvements in the demand (care-seeking) and service (facility readiness) health outcomes. Attribution is complicated by an uncontrolled health system and lack of district controls; however, the extensive scope, reach, and positive changes are promising and consistent with sustained Ugandan experiences. Best practice documentation is critical to facilitate scale-up and progress acceleration of MNCH programs in Tanzanian and East African settings.

Unlocking community capabilities for addressing social norms/practices: behavioural change intervention study to improve birth preparedness and complication readiness among pregnant women in rural Nigeria

BackgroundMaternal mortality is attributed to combination of contextual factors that cause delay in seeking care, leading to poor utilization of skilled health services. Community participation is one of the acknowledged strategies to improve health services utilization amongst the poor and rural communities. The study aimed at assessing the potentials of improving birth preparedness and complication readiness (BP/CR) using community-driven behavioural change intervention among pregnant women in rural Nigeria.MethodsA pre-post intervention study was conducted from June 2018 to October 2019 on 158 pregnant women selected through multi-stage sampling technique from 10 villages. Data on knowledge and practices of birth preparedness and utilization of facility health services were collected through interviewer-administered pre-tested structured questionnaire. Behavioural change intervention comprising of stakeholders’ engagement, health education, facilitation of emergency transport and fund saving system, and distribution of educational leaflets/posters were delivered by twenty trained volunteer community health workers. The intervention activities focused on sensitization on danger signs of pregnancy, birth preparedness and complication readiness practices and emergency response. Means, standard deviations, and percentages were calculated for descriptive statistics; and T-test and Chi square statistical tests were carried out to determine associations between variables. Statistical significance was set at p-value < 0.05.ResultsThe result showed that after the intervention, mean knowledge score of danger signs of pregnancy increased by 0.37 from baseline value of 3.94 (p < 0.001), and BP/CR elements increased by 0.27 from baseline value of 4.00 (p < 0.001). Mean score for BP/CR practices increased significantly by 0.22 for saving money. The proportion that had antenatal care (76.6%) and had facility delivery (60.0%) increased significantly by 8.2 and 8.3% respectively. Participation in Community-related BP/CR activities increased by 11.6% (p = 0.012).ConclusionWith the improvements recorded in the community-participatory intervention, birth preparedness and complication readiness should be promoted through community, household and male-partner inclusive strategies. Further evaluation will be required to ascertain the sustainability and impact of the programme.

A comparative impact evaluation of two human resource models for community-based active tuberculosis case finding in Ho Chi Minh City, Viet Nam

BackgroundTo achieve the WHO End TB Strategy targets, it is necessary to detect and treat more people with active TB early. Scale–up of active case finding (ACF) may be one strategy to achieve that goal. Given human resource constraints in the health systems of most high TB burden countries, volunteer community health workers (CHW) have been widely used to economically scale up TB ACF. However, more evidence is needed on the most cost-effective compensation models for these CHWs and their potential impact on case finding to inform optimal scale-up policies.MethodsWe conducted a two-year, controlled intervention study in 12 districts of Ho Chi Minh City, Viet Nam. We engaged CHWs as salaried employees (3 districts) or incentivized volunteers (3 districts) to conduct ACF among contacts of people with TB and urban priority groups. Eligible persons were asked to attend health services for radiographic screening and rapid molecular diagnosis or smear microscopy. Individuals diagnosed with TB were linked to appropriate care. Six districts providing routine NTP care served as control area. We evaluated additional cases notified and conducted comparative interrupted time series (ITS) analyses to assess the impact of ACF by human resource model on TB case notifications.ResultsWe verbally screened 321,020 persons in the community, of whom 70,439 were eligible for testing and 1138 of them started TB treatment. ACF activities resulted in a + 15.9% [95% CI: + 15.0%, + 16.7%] rise in All Forms TB notifications in the intervention areas compared to control areas. The ITS analyses detected significant positive post-intervention trend differences in All Forms TB notification rates between the intervention and control areas (p = 0.001), as well as between the employee and volunteer human resource models (p = 0.021).ConclusionsBoth salaried and volunteer CHW human resource models demonstrated additionality in case notifications compared to routine case finding by the government TB program. The salaried employee CHW model achieved a greater impact on notifications and should be prioritized for scale-up, given sufficient resources.

Women’s development group leaders’ promotion of maternal, neonatal and child health care in Ethiopia: a cross-sectional study

ABSTRACT Background Women’s development group leaders are volunteer community health workers in Ethiopia who, among other duties, promote health and prevention of diseases. They link and extend essential health services from health posts to households. Objective To assess the characteristics, knowledge, and practice of women’s development group leaders in the field of maternal, neonatal, and child health care. Method This study used a cluster-sampled cross-sectional survey conducted from December 2016 to February 2017 in four regions of Ethiopia: Oromia, Amhara, Tigray and Southern Nations, Nationalities and Peoples. One of the volunteers, who was available at the time of the survey, was included from each cluster. A total of 187 women’s development group leaders participated in this quantitative study. Result Close to half of the women’s development group leaders were illiterate. The leaders had a wide variation in the number of women in their groups. Two-thirds had received some training during the last year, covering a broad range of health topics. Their knowledge of maternal, newborn, and child health was relatively low. Two-thirds had monthly contact with health extension workers. Around half had interacted with other local stakeholders on maternal and child health matters during the last three months. Two-thirds had visited pregnant women, and half had made home visits after delivery in the previous quarter. Activities regarding sick newborns and under-five children were less frequent. Conclusion The women leaders were given a wide range of tasks, despite having a low educational level and receiving training through brief orientations. They also showed limited knowledge but had a relatively high level of activities related to maternal health, while less so on neonatal and child health.

Performance of volunteer community health workers in implementing home-fortification interventions in Bangladesh: A qualitative investigation.

BRAC, an international development organisation based in Bangladesh, uses female volunteer community health workers called Shasthya Shebika (SS), who receive small incentives to implement its home-fortification interventions at the community level. This paper examines the individual, community and BRAC work environment factors that exert an influence on the performance of SS. This qualitative study was conducted between the period of June 2014 to December 2016 as part of a larger evaluation of BRAC's home-fortification programme. Data were collected through in-depth interviews, focus group discussions, and key informant interviews and analysed thematically. The participants were SS and their supervisors working for BRAC, caregivers of children aged 6-59 months, husbands of SS, village doctors, and Upazila Health and Family Planning Officers. Younger, better educated and more experienced SS with positive self-efficacy were perceived to have performed better than their peers. Social and community factors, such as community recognition of the SS's services, social and religious norms, family support, and household distance, also affected the performance of the SS. There were several challenges at the programme and organisational level that needed to be addressed, including appropriate recruitment, timely basic training and income-generation guidance for the SS. BRAC's volunteer SS model faces challenges at individual, community, programme and organisational level. Importantly, BRAC's SS require a living wage to earn essential income for their family. Considering the current socio-cultural and economic context of Bangladesh, BRAC may need to revise the existing volunteer SS model to ensure that SS receive an adequate income so that they can devote themselves to implementing its home-fortification intervention.

Use of concurrent evaluation to improve implementation of a home fortification programme in Bangladesh: a methodological innovation.

This paper focuses on the use of 'concurrent evaluation' to evaluate a nationally scaled-up programme in Bangladesh that was implemented by BRAC (an international development organisation) using Shasthya Shebika (SS) - volunteer community health workers - to promote home fortification with micronutrient powders (MNP) for children under-five. We developed a programme impact pathway to conceptualise the implementation and evaluation strategy and developed a strategic partnership among the key programme stakeholders for better use of evaluation evidence. We developed a multi-method concurrent evaluation strategy to provide insights into the BRAC programme and created provision for course correction to the implementation plan while it was in operation. One hundred sixty-four sub-districts and six urban slums in Bangladesh. Caregivers of children 6-59 months, SS and BRAC's staff members. The evaluation identified low awareness about home fortification among caregivers, inadequate supply and frequent MNP stockouts, and inadequate skills of BRAC's SS to promote MNP at the community level as hindrances to the achievement of programme goals. The partners regularly discussed evaluation results during and after implementation activities to assess progress in programme coverage and any needs for modification. BRAC initiated a series of corrections to the original implementation plan to address these challenges, which improved the design of the MNP programme; this resulted in enhanced programme outcomes. Concurrent evaluation is an innovative approach to evaluate complex real-world programmes. Here it was utilised in implementing a large-scale nutrition programme to measure implementation process and effectiveness.

Role of home visits by volunteer community health workers: to improve the coverage of micronutrient powders in rural Bangladesh.

We assessed the role of home visits by Shasthya Shebika (SS) - female volunteer community health workers (CHWs) - in improving the distribution of micronutrient powder (MNP), and explored the independent effects of caregiver-provider interaction on coverage variables. We used data from three cross-sectional surveys undertaken at baseline (n 1927), midline (n 1924) and endline (n 1540) as part of an evaluation of a home fortification programme. We defined an exposure group as one that had at least one SS visit to the caregiver's household in the 12 months preceding the survey considering three outcome variables - message (ever heard), contact (ever used) and effective coverage (regular used) of MNP. We performed multiple logistic regressions to explore the determinants of coverage, employed an 'interaction term' and calculated an odds ratio (OR) to assess the modifying effect of SS's home visits on coverage. Sixty-eight sub-districts from ten districts of Bangladesh. Children aged 6-59 months and their caregivers. A home visit from an SS positively impacts message coverage at both midline (ratio of OR 1·70; 95 % CI 1·25, 2·32; P < 0·01) and endline (ratio of OR 3·58; 95 % CI 2·22, 5·78; P < 0·001), and contact coverage both at midline (ratio of OR 1·48; 95 % CI 1·06, 2·07; P = 0·021) and endline (ratio of OR 1·74; 95 % CI 1·23, 2·47; P = 0·002). There was no significant effect of a SS's home visit on effective coverage. The households visited by BRAC's volunteer CHWs have better message and contact coverage among the children aged 6-59 months.
