The perceived role of ward-based primary healthcare outreach teams in rural KwaZulu-Natal, South Africa

Views of community health workers on the integration of a physiotherapist into a ward-based outreach team

Background

Due to changes in the disease profile and lifestyle of individuals in South Africa, the limited health care facilities available have experienced congestion and overcrowding, affecting health care service delivery. Ward-based outreach team (WBOT) programmes were implemented to strengthen primary health care, improve access and alleviate the congestion occurring at these facilities. However, WBOTs have limitations in terms of medical knowledge and rehabilitative skills.

Objective

To explore the views of community health workers (CHWs) on the integration of physiotherapists into WBOTs.

Method

A qualitative research design making use of focus group discussions (FGDs) was used. Through purposive sampling, 58 CHWs who were members of WBOTs were recruited. The WBOTs were from 10 selected primary health care centres in the Tshwane district, Region 2. Six FGDs were conducted. The audio-recorded data were transcribed verbatim. The transcripts were transported into NVivo 12 for thematic analysis.

Results

The views of the CHWs were that the WBOTs can benefit from having a physiotherapist as a member of the team. The WBOTs do not have adequate skills to attend to the physiotherapy needs of communities. People in the community have challenges in accessing physiotherapy services, and physiotherapy services can enhance the performance of the WBOTs by providing training to the WBOTs and providing clinical services to community members.

Conclusion

Community-based rehabilitative services with a physiotherapist as part of the WBOTs can enhance and strengthen the services of the WBOTs, which can improve the treatment outcomes for communities.

Clinical implications

The WBOTS will be empowered to provide clinical services to the vulnerable people in the community that they serve.

Alternative mechanisms for delivery of medication in South Africa: A scoping review

BACKGROUND

The number of people in South Africa with chronic conditions is a challenge to the health system. In response to the coronavirus infection, health services in Cape Town introduced home delivery of medication by community health workers. In planning for the future, they requested a scoping review of alternative mechanisms for delivery of medication to patients in primary health care in South Africa.

METHODS

Databases were systematically searched using a comprehensive search strategy to identify studies from the last 10 years. A methodological guideline for conducting scoping reviews was followed. A standardised template was used to extract data and compare study characteristics and findings. Data was analysed both quantitatively and qualitatively.

RESULTS

A total of 4253 publications were identified and 26 included. Most publications were from the last 5 years (n = 21), research (n = 24), Western Cape (n = 15) and focused on adherence clubs (n = 17), alternative pick-up-points (n = 14), home delivery (n = 5) and HIV (n = 17). The majority of alternative mechanisms were supported by a centralised dispensing and packaging system. New technology such as smart lockers and automated pharmacy dispensing units have been piloted. Patients benefited from these alternatives and had improved adherence. Available evidence suggests alternative mechanisms were cheaper and more beneficial than attending the facility to collect medication.

CONCLUSION

A mix of options tailored to the local context and patient choice that can be adequately managed by the system would be ideal. More economic evaluations are required of the alternatives, particularly before going to scale and for newer technology.

Exploring the promise and reality of ward-based primary healthcare outreach teams conducting TB household contact tracing in three districts of South Africa

Background

Tuberculosis (TB) household contact tracing is a form of targeted active case-finding for which community health workers (‘outreach teams’) in South Africa are primarily responsible for its implementation. We conducted an exploratory qualitative study to understand the role of outreach teams in delivering TB household contact tracing.

Methods

The study took place in three districts of South Africa between May 2016 and February 2017. We conducted 78 in-depth interviews (IDI) (comprising 35 key stakeholders, 31 TB index patients and 12 HHCs) and five focus group discussions (FGD) (40 outreach team members in four FGDs and 12 community stakeholders in one FGD).

Results

Outreach teams contributed positively by working across health-related programmes, providing home-based care and assisting with tracing of persons lost to TB care. However, outreach teams had a limited focus on TB household contact tracing activities, likely due to the broad scope of their work and insufficient programmatic support. Outreach teams often confused TB household contact tracing activities with finding persons lost to TB care. The community also had some reservations on the role of outreach teams conducting TB household contact tracing activities.

Conclusions

Creating awareness among outreach workers and clinic personnel about the importance of and activities related to TB household contact tracing would be required to strengthen the delivery of TB household contact tracing through the community-based primary health care teams. We need better monitoring and evaluation systems, stronger integration within a realistic scope of work, adequate training on TB household contact tracing and TB infection prevention control measures. Involving the community and educating them on the role of outreach teams could improve acceptance of future activities. These timely results and lessons learned should inform contact tracing approaches in the context of COVID-19.

Barriers to the Implementation of the Ward-Based Outreach Team Program in Mpumalanga Province: Results From Process Evaluation

Background:

South Africa adopted the ward-based outreach team (WBOT) program as one aspect of the three-stream approach to primary health care (PHC) re-engineering. PHC re-engineering seeks to modify the hospicentric and curative approach into a more preventive and promotive approach to improve health outcomes. There has not been an evaluation of the implementation of the WBOTs in Nkangala District since its inception in 2012.

Methods:

A process evaluation approach using qualitative methods was used to examine and describe the contextual, organizational, health provider, and program-related barriers considered to affect the implementation of the WBOTs 3 sub-districts in one of the health districts in Mpumalanga Province, South Africa. The framework for this evaluation was informed by the logic model framework developed by the Center for Disease Control as well as the 3 domains of evaluation recommended by the Medical Research Council Guidance on process evaluation. Data were collected through in-depth interviews with multiple data sources directly involved in the implementation of the WBOTs. A thematic analysis was done using NVivo 11.

Results:

The key critical barriers identified by the evaluation include the inadequate provision of resources, the lack of supervision, the heavy workload for outreach teams, the inadequate and irregular payment of stipends, threats to the safety of the CHWs, and the cultural beliefs and practices of the communities who are to receive the services. The lack of adequate financial resources was the main challenge, and will continue to pose a risk to the successful implementation of the WBOTs.

Conclusions:

Although the barriers are being reported as separate contextual factors, the internal and external contexts are interdependent, interact with one each other, and should not be considered in isolation. The need to improve stakeholder engagement on the WBOT program underscores the importance of the external context in the successful implementation of WBOTs.

Developing stakeholder participation to address lack of safe water as a community health concern in a rural province in South Africa

BACKGROUND

Despite legislative and policy commitments to participatory water governance in South Africa, and some remarkable achievements, there has been limited progress to improve the water infrastructure servicing in marginalized rural communities. Around five million South Africans still do not have access to safe water.

OBJECTIVE

This paper seeks to understand and advance processes to engage multisectoral stakeholders to respond to lack of safe water as a community-nominated health priority in rural South Africa.

METHOD

We engaged representatives from Mpumalanga Department of Health (MDoH), rural communities, other government departments and non-governmental organisations (NGOs) to cooperatively generate, interpret and act on evidence addressing community-nominated priorities. A series of participatory workshops were conducted where stakeholders worked together as co-researchers to develop shared accounts of the problem, and recommendations to address it. Consensus on the problem, mapping existing planning and policy landscapes, and initiating constructive dialogue was facilitated through group discussions in a collective learning process.

RESULTS

Community stakeholders nominated lack of safe water as a local priority public health issue and generated evidence on causes and contributors, and health and social impacts. Together with government and NGO stakeholders, this evidence was corroborated. Stakeholders developed a local action plan through consensus and feasibility appraisal. Actions committed to behavioural change and reorganization of existing services, were relevant to the needs of the local community and were developed with consideration of current policies and strategies. A positive, collective reflection was made on the process. The greatest gain reported was the development of dialogue in 'safe spaces' through which mutual understanding, insights into the functioning of other sectors and learning by doing were achieved.

CONCLUSION

Our process reflected willingness and commitment among stakeholders to work together collectively addressing local water challenges. Location in an established public health observatory helped to create neutral, mediated spaces for participation.

The Perspectives of Programme Staff and Recipients on the Acceptability and Benefits of the Ward-Based Outreach Teams in a South African Province

The re-engineering of primary health care (PHC) called for the establishment of ward-based outreach teams as a reform strategy to bridge the gap between health facilities and communities. The Nkangala district established ward-based outreach teams in 2012. We used process evaluation to assess the acceptability of the outreach teams from the perspectives of those involved in the implementation as well as the clients who are the recipients of the outreach services in order to describe how the programme benefits the recipients, the staff, and the health system. Data were collected through interviews with multiple data sources. A thematic analysis was done using NVivo 11. The outreach programme is acceptable to the recipients and staff. The acceptability translated into measurable benefits for the recipients and the health system. Health benefits included increased access to services, support for treatment adherence, and linkages to various sector departments for social support. Since the inception of outreach teams, the district has recorded low utilisation of PHC services and improved priority indicators such as immunisation coverage, early antenatal bookings, treatment adherence, TB cure rates, and decreased default rates. The positive effects of the outreach teams on indicators underscore the need to roll the programme out to all sub-districts.

Community health worker motivation to perform systematic household contact tuberculosis investigation in a high burden metropolitan district in South Africa

BACKGROUND

South Africa faces a chronic shortage of professional health workers. Accordingly, community health workers (CHWs) are being employed to mitigate the ongoing health workforce deficiencies. As increased access to quality service delivery hinges upon their motivation, this study explored CHWs' motivation to deliver systematic household contact tuberculosis (TB) investigation (SHCI).

METHODS

In 2017, a cross-sectional survey was conducted among CHWs in the Mangaung Metropolitan District, Free State Province. Exploratory factor analysis was performed on a 30-item scale to determine the dimensions underlying CHW motivation. Items with factor loadings of 0.4 and above were retained. Descriptive and inferential analyses were used to determine CHW motivation levels. Multiple linear regression analysis was used to investigate the determinants of CHW motivation.

RESULTS

Out of 235 participants, 89.2% were female. Participants' median age was 39 (inter-quartile range: 33-45) years. CHW motivation was defined by 16 items across three dimensions - intrinsic job satisfaction, burnout and team commitment, together explaining 56.04% of the total variance. The derived scale showed satisfactory internal consistency (Cronbach's alpha: 0.81), with a mean motivation score of 52.26 (standard deviation [sd]: 5.86) out of 64. Statistically significant differences were observed between formal CHWs - those with at least phase 1 standardised accredited training, and informal CHWs - those without such accredited training regarding team commitment scores (17.82 [sd: 2.48] vs. 17.07 [sd: 2.82]; t(233) = 2.157; p = 0.013). CHW age (β = 0.118, p = 0.029), location (β = 1.737, p = 0.041), length of service (β = - 0.495, p < 0.001), attendance of TB SHCI training (β = 1.809, p = 0.036), and TB SHCI competence (β = 0.706, p < 0.001), contributed statistically significantly to CHW motivation.

CONCLUSION

CHW motivation to perform TB SHCI was both intrinsic and extrinsic. The high overall mean score implies that the CHWs were well-motivated to perform TB SHCI. To ensure sustained improved access to quality TB SHCI service provision, programme managers in the Free State and similar settings could potentially use the tool derived from this study to monitor and inform CHW motivation interventions. Interventions should pay close attention to the CHWs' formalisation, competence and training.

Review of Ongoing Activities and Challenges to Improve the Care of Patients With Type 2 Diabetes Across Africa and the Implications for the Future

Background

There has been an appreciable increase in the number of people in Africa with metabolic syndrome and Type 2 diabetes (T2DM) in recent years as a result of a number of factors. Factors include lifestyle changes, urbanisation, and the growing consumption of processed foods coupled with increasing levels of obesity. Currently there are 19 million adults in Africa with diabetes, mainly T2DM (95%), estimated to grow to 47 million people by 2045 unless controlled. This has a considerable impact on morbidity, mortality and costs in the region. There are a number of issues to address to reduce the impact of T2DM including improving detection rates and current access to services alongside addressing issues of adherence to prescribed medicines. There are also high rates of co-morbidities with infectious diseases such as HIV and tuberculosis in patients in Africa with T2DM that require attention.

Objective

Document ongoing activities across Africa to improve the care of patients with T2DM especially around issues of identification, access, and adherence to changing lifestyles and prescribed medicines. In addition, discussing potential ways forward to improve the care of patients with T2DM based on ongoing activities and experiences including addressing key issues associated with co-morbidities with infectious diseases.

Our Approach

Contextualise the findings from a wide range of publications including internet based publications of national approaches coupled with input from senior level government, academic and other professionals from across Africa to provide future guidance.

Ongoing Activities

A number of African countries are actively instigating programmes to improve the care of patients with T2DM starting with improved diagnosis. This recognises the growing burden of non-communicable diseases across Africa, which has been neglected in the past. Planned activities include programmes to improve detection rates and address key issues with diet and lifestyle changes, alongside improving monitoring of care and activities to enhance adherence to prescribed medicines. In addition, addressing potential complexities involving diabetes patients with infectious disease co-morbidities. It is too early to fully assess the impact of such activities.

Conclusion

There are a number of ongoing activities across Africa to improve the management of patients with diabetes including co-morbidities. However, more needs to be done considering the high and growing burden of T2DM in Africa. Ongoing research will help further benefit resource allocation and subsequent care.

Perceived needs of patients and family caregivers regarding home-based enteral nutritional therapy in South Africa: A qualitative study

INTRODUCTION

The need for specialized care, particularly enteral nutritional therapy in community settings is now increasing with implications for both patients and primary care providers. More research is needed to identify the needs of patients and primary caregivers. The study aimed to explore the perceived support needs regarding the provision of home-based enteral nutritional therapy among critically ill adult patients and family caregivers in the KwaZulu-Natal Province of South Africa.

METHODS

A qualitative study of purposely selected adult patients on homebased enteral nutritional therapy and family caregivers was conducted in a district hospital, a community health centre, two primary health care clinics and selected households in the KwaZulu-Natal Province, South Africa. Semi-structured individual interviews were conducted between June and September 2018 and the content analysis approach was used to analyse data.

RESULTS

Two major themes and five subthemes emerged from the results of the interviews. The major themes concerned socioeconomic and psychosocial support needs related to the provision of home-based enteral nutritional therapy. Subthemes included the need for financial assistance, need for enteral nutrition products and supplementary supplies, need for infrastructure for continuity of care, and psychological support needs.

CONCLUSION

Results of this study confirm the need for developing strategies adapted to a South African context and yonder to meet patients' and family caregivers' needs with regard to nutritional services. More research on the identification of needs through monitoring and evaluation of the implementation of nutritional guidelines is needed, particularly in the district hospital and primary health care (PHC) setting.

Resource requirements for community-based care in rural, deep-rural and peri-urban communities in South Africa: A comparative analysis in 2 South African provinces

INTRODUCTION

As South Africa embarks on the implementation of the community health care worker (CHW) 2018 policy, quantifying the resource requirements to effectively manage the programme across different geographical communities is essential. This study was conducted to quantify and compare costs associated with travel and service delivery demands on CHWs between area types in two districts.

METHODS

This economic analysis adopted a provider perspective to cost CHW services between January and November 2016. A total of 221 CHWs completed diaries for 10 days to document their activities. Quintile regression and the Kruskall Wallis test were used to test for differences in time and activities across urban and rural sites.

RESULTS

While travel time across rural and urban settings within each district did differ it was not the most significant predictor of differences in time utilization. Time on activities showed more significant differences with overall median time by unit of activity being 15% longer in rural than urban areas in Sedibeng and 10% longer in uMzinyathi respectively. Most CHW time was spent conducting home visits (57% in rural,66% in peri-urban/urban). Median time per home visit in uMzinyathi was 50% longer in deep-rural areas than urban areas and 20% longer in rural than urban areas in Sedibeng. Referrals and number of home visits per capita (0.4 visits in rural and 0.7 in urban/peri-urban areas) were low in both districts. Expenditure on the programme translated to under 4% of PHC expenditure per capita and remains under 5% if despite the new national minimum wage (R3,500/$245).

CONCLUSION

Because home visits take longer and CHWs spend a lower share of time on visits, a higher number is required in rural and deep rural areas (33% and 66% respectively) than in urban areas. Effective budget planning will therefore need to recognize the different geographical needs.

Sub-national perspectives on the implementation of a national community health worker programme in Gauteng Province, South Africa

INTRODUCTION

In 2011, in line with principles for Universal Health Coverage, South Africa formalised community health workers (CHWs) into the national health system in order to strengthen primary healthcare. The national policy proposed that teams of CHWs, called Ward-based Primary Healthcare Outreach Teams (WBPHCOTs), supervised by a professional nurse were implemented. This paper explores WBPHCOTs' and managers' perspectives on the implementation of the CHW programme in one district in South Africa at the early stages of implementation guided by the Implementation Stages Framework.

METHODS

We conducted a qualitative study consisting of five focus group discussions and 14 in-depth interviews with CHWs, team leaders and managers. A content analysis of data was conducted.

RESULTS

There were significant weaknesses in early implementation resulting from a vague national policy and a rushed implementation plan. During the installation stage, adaptations were made to address gaps including the appointment of subdistrict managers and enrolled nurses as team leaders. Staff preparation of CHWs and team leaders to perform their roles was inadequate. To compensate, team members supported each another and assisted with technical skills where they could. Structural issues, such as CHWs receiving a stipend rather than being employed, were an ongoing implementation challenge. Another challenge was that facility managers were employed by the local government authority while the CHW programme was perceived to be a provincial programme.

CONCLUSION

The implementation of complex programmes requires a shared vision held by all stakeholders. Adaptations occur at different implementation stages, which require a feedback mechanism to inform the implementation in other settings. The CHW programme represented a policy advance but lacked detail with respect to human resources, budget, supervision, training and sustainability, which made it a difficult furrow to plough. This study points to how progressive reform remains fraught without due attention to the minutiae of practice.

Benefits of health reform for households in rural South Africa following implementation of ward-based primary healthcare outreach teams: a qualitative inquiry

Background: Major national primary healthcare reforms are seldom implemented, and few studies have explored the benefits of primary healthcare outreach teams to rural households, a knowledge gap we sought to address with this study.

Objective: The objective of this study was to explore the community benefits in the context of PHC services delivered in rural households by outreach teams.

Methods: The study was conducted in the iLembe District on the east coast of KwaZulu-Natal, South Africa between July 2015 and January 2017. In-depth, explorative and semi-structured qualitative interviews were conducted as part of a mixed-method study. A total of 21 in-depth interviews with key informants and four focus group discussions (n = 28) were conducted with purposefully sampled households and outreach team members. Content analysis was used to explore and understand the households’ experiences of primary healthcare services provided by outreach teams.

Results: Household members benefited from outreach team services tailored to specific households and individuals, which improved the efficiency of healthcare services, access to appropriate health information and the overall experience of healthcare, particularly among those who are physically unwell, on chronic treatment, default treatment or immunisation, or who need referrals for clinical and social services. The benefits to household members included personalised care in the home, improved referral pathways, awareness of health events, improved adherence to treatment and reduction in opportunity costs of healthcare.

Conclusion: It is perceived that participants have benefitted from the model of PHC service delivery by outreach teams through improved access to healthcare services, and by allowing community members to receive services that are responsive to their needs since the outreach team members’ advocate and negotiate to deliver services on behalf of community members. These stated benefits, as perceived by household members, have the potential to improve health outcomes and increase satisfaction levels amongst household members.

National guidance and district-level practices in the supervision of community health workers in South Africa: a qualitative study

BACKGROUND

Supportive supervision is considered critical to community health worker programme performance, but there is relatively little understanding of how it can be sustainably done at scale. Supportive supervision is a holistic concept that encompasses three key functions: management (ensuring performance), education (promoting development) and support (responding to needs and problems). Drawing on the experiences of the ward-based outreach team (WBOT) strategy, South Africa's national community health worker (CHW) programme, this paper explores and describes approaches to supportive supervision in policy and programme guidelines and how these are implemented in supervision practices in the North West Province, an early adopter of the WBOT strategy. Outreach teams typically consist of six CHWs plus a nurse outreach team leader (OTL).

METHODS

A qualitative, descriptive study that combined a document review of national policy and guidelines with key informant interviews in two districts of the North West Province was conducted. An overall WBOT policy statement and four guidelines on aspects of the strategy, spanning the period 2011-2017, were reviewed for statements on the three core facets of supervision outlined above. Eight focus group discussions, involving facility managers, team leaders and community health workers (total 40 respondents), purposively selected from four sub-districts in two districts, assessed local-level supervision practices. Alignment across policy and guidance documents and between policy/guidance and practice was examined.

FINDINGS

While all the official policy documents and guidelines reviewed acknowledged the need for supervision and support, these elements were inadequately developed and poorly aligned, both in terms of scope and in providing firm guidance on the supervision of WBOTs. The practices of supervision entailed a variety of reporting lines, while development and support processes were informal and often lacking, and teams poorly resourced. There was internal cohesion and support within teams amongst CHWs and between CHWs and OTLs. However, primary health care clinic managers, who were supposed to supervise the WBOTs, struggled to fulfil this role amidst the high workloads in facilities, and relationships between WBOTs and facility staff often remained strained.

CONCLUSION

This study identified weaknesses in both the design and implementation of the supervision system of WBOTs. The lack of explicit, coherent and holistic guidance in policy and the failure to address constraints to supervision at local level undermine the performance and sustainability of the WBOT strategy in South Africa.
