The effect of supervision on community health workers' effectiveness with households in rural South Africa: A cluster randomized controlled trial.

BACKGROUND: Community health workers (CHWs) can supplement professional medical providers, especially in rural settings where resources are particularly scarce. Yet, outcomes of studies evaluating CHWs effectiveness have been highly variable and lack impact when scaled nationally. This study examines if child and maternal outcomes are better when existing government CHWs, who are perinatal home visitors, receive ongoing enhanced supervision and monitoring, compared to standard care. METHODS AND FINDINGS: A cluster randomized controlled effectiveness trial was conducted comparing outcomes over 2 years when different supervision and support are provided. Primary health clinics were randomized by clinic to receive monitoring and supervision from either (1) existing supervisors (Standard Care (SC); n = 4 clinics, 23 CHWs, 392 mothers); or (2) supervisors from a nongovernmental organization that provided enhanced monitoring and supervision (Accountable Care [AC]; n = 4 clinic areas, 20 CHWs, 423 mothers). Assessments were conducted during pregnancy and at 3, 6, 15, and 24 months post-birth with high retention rates (76% to 86%). The primary outcome was the number of statistically significant intervention effects among 13 outcomes of interest; this approach allowed us to evaluate the intervention holistically while accounting for correlation among the 13 outcomes and considering multiple comparisons. The observed benefits were not statistically significant and did not show the AC's efficacy over the SC. Only the antiretroviral (ARV) adherence effect met the significance threshold established a priori (SC mean 2.3, AC mean 2.9, p < 0.025; 95% CI = [0.157, 1.576]). However, for 11 of the 13 outcomes, we observed an improvement in the AC compared to the SC. While the observed outcomes were not statistically significant, benefits were observed for 4 outcomes: increasing breastfeeding for 6 months, reducing malnutrition, increasing ARV adherence, and improving developmental milestones. The major study limitation was utilizing existing CHWs and being limited to a sample of 8 clinics. There were no major study-related adverse events. CONCLUSIONS: Supervision and monitoring were insufficient to improve CHWs' impact on maternal and child outcomes. Alternative strategies for staff recruitment and narrowing the intervention outcomes to the specific local community problems are needed for consistently high impact.

'Community health workers are unable to work because they don't have supervisors' - mid-level providers' experiences of a CHW program in rural South Africa.

INTRODUCTION: The World Health Organization has called for more than 4 million community health workers (CHWs) globally; yet there are gaps in the evidence of CHWs' impact where studies have not had consistent results. South Africa is currently investing in CHW programs. However, there are significant concerns about the implementation and effectiveness of the program. METHODS: We interviewed mid-level supervisors involved in eight rural clinics in a deeply rural South African municipality to identify the strengths and weaknesses of the CHW programs currently being implemented. Half of these clinics were part of a program providing enhanced supervision to CHWs, and the remainder were operating as usual. We hypothesized that stakeholders would provide valuable insights on how to improve the implementation of CHW programs. Fourteen interviews with supervisors from three levels of clinic and non-governmental organizations were conducted. Interviews were transcribed and translated from isiXhosa to English, and thematically analysed using ATLAS.ti. RESULTS: Two overarching themes emerged: challenges at the national CHW program level (loss of political support, inadequacy of supervision and access to resources, human resource considerations); and experiences of the enhanced-supervision model provided (engagement and buy-in, link between CHW program and healthcare facilities, improvements through the intervention). Our findings suggest that CHWs operate largely unsupported, with limited access to training, equipment and supervision. The enhanced-supervision intervention appeared to mitigate some of these shortfalls. To make CHW programs efficient, we need to recruit CHWs based on social and administrative competence (rather than network referrals), provide improved higher quality training, provide more resources, especially equipment and transport, and ensure that CHWs receive supportive supervision that goes beyond simply administrative supervision. Furthermore, our findings suggest that the intervention in this study has somewhat mitigated these challenges through a package of supportive supervision and additional resources, highlighting the importance of stakeholder engagement and buy-in. It is clear that the governmental CHW program has many challenges - a number of which were temporarily mitigated by the intervention tested in this research's parent study. A list of recommendations for practice was developed from this work. First, contracts and reimbursements are important for CHW motivation, and are seen as essential prerequisites for CHW program success. Second, CHWs and other stakeholders must be involved in the design and implementation of the CHW program. Third, good-quality training and refresher trainings for CHWs is critical. Fourth, access to equipment such as scales is needed. Fifth, transport is critical in rural areas to access patients in remote areas. Lastly, supportive supervision was described as of upmost importance. CONCLUSION: CHWs have the potential to provide invaluable support in communities, and in rural communities in particular - but they need to operate in a functional supportive system. More resources need to be allocated to training, equipment and supportive supervision.

Are we listening to community health workers? Experiences of the community health worker journey in rural South Africa.

Access to healthcare in developing countries remains a challenge. As a result, task-shifting to community health workers (CHWs) is increasingly used to mitigate healthcare worker shortages. Although there is solid evidence of CHW program effectiveness, less is known about CHWs' experiences of becoming and then working daily as CHWs-information that should play an important role in the design of CHW programs. We examined the experiences of a group of CHWs working in a government-run CHW program in South Africa's rural Eastern Cape Province. Semistructured qualitative interviews (N = 9) and focus groups (N = 2) focusing on motivations for becoming a CHW and experiences of working as CHWs were conducted and thematically analyzed. Three themes were identified: (1) becoming a CHW, (2) facing challenges in the field, and (3) gaining community acceptance through respect and legitimacy. In this study, CHWs were motivated by altruism and a desire to help their community. They faced a range of challenges such as limited training, lack of supervision, equipment shortages, logistical issues, and clinics with limited services. Respect and legitimacy through community acceptance and trust is crucial for effective CHW work. CHWs in this study described how confidentiality and their own persistence facilitated the process of gaining respect and legitimacy. CHWs have a unique knowledge of contexts and requirements for successful programs and greater efforts are needed to include their perspectives to improve and develop programs. Recognition is needed to acknowledge the significant personal input required by CHWs for programs to be successful.

Maternal and child health outcomes in rural South African mothers living with and without HIV.

In the era of widespread antiretroviral therapy (ART), consequences of being HIV-exposed is unclear for children, especially in rural communities. A population sample of consecutive births (470/493) in the Eastern Cape of South Africa (SA) were recruited and reassessed at five points over the first 24 months. Maternal and child outcomes between mothers living with and without HIV were assessed using multiple linear and logistic regressions. At birth, 28% of the sample was mothers living with HIV and five additional mothers seroconverted. All mothers living with HIV reported taking ART. The rate of depressed mood and IPV was similar across serostatus. However, mothers living with HIV significantly decreased their alcohol use after learning about their pregnancy and were more likely to exclusively breastfeed when compared to mothers without HIV. Despite maternal HIV status, children had similar growth across the first 24 months of life. Future work is needed to assess if these developmental trajectories will persist.

Community health workers impact on maternal and child health outcomes in rural South Africa - a non-randomized two-group comparison study.

BACKGROUND: Home visits by paraprofessional community health workers (CHWs) has been shown to improve maternal and child health outcomes in research studies in many countries. Yet, when these are scaled or replicated, efficacy disappears. An effective CHW home visiting program in peri-urban Cape Town found maternal and child health benefits over the 5 years point but this study examines if these benefits occur in deeply rural communities. METHODS: A non-randomized, two-group comparison study evaluated the impact of CHW in the rural Eastern Cape from August 2014 to May 2017, with 1310 mother-infant pairs recruited in pregnancy and 89% were reassessed at 6 months post-birth. RESULTS: Home visiting had limited, but important effects on child health, maternal wellbeing and health behaviors. Mothers reported fewer depressive symptoms, attended more antenatal visits and had better baby-feeding practices. Intervention mothers were significantly more likely to exclusively breastfeed for 6 months (OR: 1.8; 95% CI: 1.1, 2.9), had lower odds of mixing formula with baby porridge (regarded as detrimental) (OR: 0.4; 95% CI: 0.2, 0.8) and were less likely to consult traditional healers. Mothers living with HIV were more adherent with co-trimoxazole prophylaxis (p < 0.01). Intervention-group children were significantly less likely to be wasted (OR: 0.5; 95% CI 0.3-0.9) and had significantly fewer symptoms of common childhood illnesses in the preceding two weeks (OR: 0.8; 95% CI: 0.7,0.9). CONCLUSION: The impact of CHWs in a rural area was less pronounced than in peri-urban areas. CHWs are likely to need enhanced support and supervision in the challenging rural context.

Home visits by community health workers in rural South Africa have a limited, but important impact on maternal and child health in the first two years of life.

BACKGROUND: More than 50% of Africa's population lives in rural areas, which have few professional health workers. South Africa has adopted task shifting health care to Community Health Workers (CHWs) to achieve the Sustainable Development Goals, but little is known about CHWs' efficacy in rural areas. METHODS: In this longitudinal prospective cohort study, almost all mothers giving birth (N = 470) in the Zithulele Hospital catchment area of the OR Tambo District were recruited and repeatedly assessed for 2 years after birth with 84.7-96% follow-up rates. During the cohort assessment we found that some mothers had received standard antenatal and HIV care (SC) (n = 313 mothers), while others had received SC, supplemented with home-visiting by CHWs before and after birth (HV) (n = 157 mothers, 37 CHWs). These visits were unrelated to the cohort study. Multiple linear and logistic regressions evaluated maternal comorbidities, maternal caretaking, and child development outcomes over time. RESULTS: Compared to mothers receiving SC, mothers who also received home visits by CHWs were more likely to attend the recommended four antenatal care visits, to exclusively breastfeed at 3 months, and were less likely to consult traditional healers at 3 months. Mothers in both groups were equally likely to secure the child grant, and infant growth and achievement of developmental milestones were similar over the first 2 years of life. CONCLUSION: CHW home visits resulted in better maternal caretaking, but did not have direct benefits for infants in the domains assessed. The South African Government is planning broad implementation of CHW programmes, and this study examines a comprehensive, home-visiting model in a rural region.

A longitudinal cohort study of rural adolescent vs adult South African mothers and their children from birth to 24 months.

BACKGROUND: Adolescent motherhood has been repeatedly linked to poor child outcomes in high income countries and urban areas in low- and middle-income countries. We examine the structural, personal, and caretaking challenges of adolescent mothers and their children in rural South Africa compared to adult mothers over the first 24 months post-birth. METHODS: A cohort of sequential births (n = 470/493) in the rural OR Tambo District was recruited and reassessed at 3, 6, 9, 12, and at 24 months post-birth, with a retention rate above 84% at all timepoints. Maternal and child outcomes were examined over time using multiple linear and logistic regressions. RESULTS: Adolescent mothers reflect 17% of births (n = 76/458). Adolescent mothers were more likely to have water in their households, but less likely to live with a partner and to be seropositive for HIV than adult mothers. Risks posed by mental health symptoms, alcohol, and partner violence were similar. Adolescents exclusively breastfed for shorter time and it took longer for them to secure a child grant compared to adult mothers. Although obtaining immunizations was similar, growth was significantly slower for infants of adolescent mothers compared to adult mothers over time. CONCLUSIONS: In rural South Africa, almost one in five pregnant women is an adolescent. Caretaking tasks influencing child growth, especially breastfeeding and securing the child grant appear as the greatest problems for adolescent compared to adult mothers.

Implementing a social innovation for community-based peer support for immigrant mothers in Sweden: a mixed-methods process evaluation.

Introduction: A South African social innovation based on peer support for mothers was contextualized in southern Sweden. The objective of the project was to support expectant women and mothers of young children in immigrant communities to access public services that would benefit maternal and child health. This study aimed to assess how the intervention was implemented, what the contextual barriers and facilitators were, and how the implementation was perceived by those who delivered and received it. Methods: The study used mixed methods with a convergent parallel design and followed the Medical Research Council guidance on process evaluations of complex interventions. Semi-structured interviews (n = 19) were conducted with peer supporters, client mothers, and key stakeholders involved in the intervention. The qualitative data were analyzed using content analysis. Quantitative data on peer supporters' activities were collected during contacts with client mothers and were presented descriptively. Results: The five peer supporters had 1,294 contacts with client mothers, of which 507 were first-time contacts. The reach was perceived as wide, and the dose of the intervention was tailored to individual needs. Barriers to implementation included community mistrust of social services, norms on gender roles and parenting, and funding challenges. The implementation was facilitated by the organization's reputation, network, experience, and third-sector affiliation. Peer supporters tended to prioritize linking clients to other services over the educational components of the intervention, sometimes doing more than what was originally planned. Implementation strategies used included building trust, using multiple outreach venues, using internal support structures, and providing practical assistance as an entry point to comprehensive psychosocial support. The personal connection between peer supporters and clients was highly valued, and the building of relationships enabled them to address sensitive topics. Peer supporters sometimes experienced a blurred line between professional and personal roles. Conclusions: Peer supporters used a variety of strategies to navigate identified barriers and facilitators. Trust was central both as a contextual factor and a strategy for implementation. It is valuable to maintain a balance between flexibility and adherence to the function of peer supporters. Further research is needed to evaluate the effects of the intervention.

Community health workers' experiences of supervision in maternal and child health programmes in low- and middle-income countries: A qualitative evidence synthesis.

Maternal and child health programmes often use Community Health Workers (CHWs) to help address poor access to health care, particularly in low- and middle-income countries (LMIC). Supervision has long been recognised as a critical ingredient of successful CHW programmes, yet it is often reported as either of poor quality or absent. There is little research on CHWs' own perception of supervision and to the best of our knowledge, there are no reviews synthesising the evidence of CHWs' experiences of supervision. This review identified and synthesised qualitative research evidence about the experiences and perceptions of supervision by CHWs in programmes targeting maternal and child health (MCH) in LMIC. Electronic searches were performed in the following databases: EMBASE, Medline, PsycINFO, ASSIA, ERIC and CINAHL. This review included studies during the period from 2000 to 2021. In total, 10,505 titles were screened for inclusion, of which 177 full-text articles were retrieved and assessed. Ultimately, 19 articles were included in this review. Data extraction was based on the thematic synthesis approach: coding the text of included studies line-by-line; developing descriptive themes; and generating analytical themes. Four themes emerged: (1) frequency of supervision, (2) type of supervision, (3) supervision and motivation and (4) supportive supervision. Careful consideration needs to be taken of the model of supervision used, as primary care facility-based supervisors (usually nurses), although skilled, may not have sufficient time to supervise. Employing supervisors whose sole responsibility is to supervise CHWs may be a good strategy to alleviate these issues. Sufficient time and resources need to be allocated to supervisors and they should be expected to perform regular in-the-field supervision. Involving some aspects of community oversight should also be considered. Supervisor skills and training and the long-term retention of trained supervisors also need to be an important area of focus.

Community health worker home visiting in deeply rural South Africa: 12-month outcomes.

Home visiting by community health workers (CHW) improves child outcomes in efficacy trials, there is however limited evidence of impact evaluating CHW programmes when operating outside of a research project. A CHW programme, previously demonstrated efficacious in a peri-urban township, was evaluated in a deeply rural context in a non-randomised comparative cohort study. Two non-contiguous, rural areas in the Eastern Cape of South Africa of about equal size and density were identified and 1469 mother-infant pairs were recruited over 33 months. In one area, CHWs conducted perinatal home visits (intervention group). Mothers in the comparison group received standard clinic care. Maternal and child outcomes were compared between the groups at one year. Mothers in the intervention group had significantly fewer depressive symptoms than mothers in the comparison group. Children of intervention mothers attained a higher proportion of their developmental milestones, compared to children in the comparison group. There were no other significant differences between mothers and children in the two groups. It is important to establish key parameters for implementing efficacious CHW programmes, especially as the numbers of CHWs are rapidly increased and are becoming critical components of task-shifting strategies of health departments in low and middle income countries (LMIC).
