Skills2Care: An innovative, cooperative learning programme for community health workers in South Africa

Background

Community health workers (CHWs) hold potential to support universal health coverage and better health for vulnerable communities. They are integral to the re-engineered Primary Health Care (PHC) strategy, introduced in South Africa in 2011. This study focussed on how to train CHWs in large numbers, especially in resource-limited, rural settings. Skills2Care, a method of cooperative learning for CHWS, has been pioneered in the Eastern Cape of South Africa.

Aim

To determine whether Skills2Care could improve the cognitive knowledge of CHWs; to understand their response and attitude to the programme; to explore factors that enabled and inhibited learning and to consider its viability as a training method.

Setting

Research was conducted in 2019 in the Ngqeleni subdistrict of the O.R. Tambo district, in rural Eastern Cape.

Methods

A group-learning model using specifically tailored study modules in booklet format, addressing mother and baby care, was used. A facilitator promoted learning. Knowledge assessment was conducted by pre- and post-study testing using multiple choice questions. Focus group discussions and interviews explored the appropriateness and acceptability of this method, and factors enabling and inhibiting the learning.

Results

This method of peer group cooperative learning can significantly increase the cognitive knowledge of CHWs. Test scores indicated a significant (13%) improvement. Focus group discussions indicated that participants valued this method as it increased knowledge and boosted their confidence.

Conclusion

This innovative approach to district-based, continuing education suggests that CHWs could be trained in large numbers without the need for additional resources.

VIBRA trial - Effect of village-based refill of ART following home-based same-day ART initiation vs clinic-based ART refill on viral suppression among individuals living with HIV: protocol of a cluster-randomized clinical trial in rural Lesotho

BACKGROUND

There is a need for evaluating community-based antiretroviral therapy (ART) delivery models to improve overall performance of HIV programs, specifically in populations that may have difficulties to access continuous care. This cluster-randomized clinical trial aims to evaluate the effectiveness of a multicomponent differentiated ART delivery model (VIBRA model) after home-based same-day ART initiation in remote villages in Lesotho, southern Africa.

METHODS/DESIGN

The VIBRA trial (VIllage-Based Refill of ART) is a cluster-randomized parallel-group superiority clinical trial conducted in two districts in Lesotho, southern Africa. Clusters (i.e., villages) are randomly assigned to either the VIBRA model or standard care. The clusters are stratified by district, village size, and village access to the nearest health facility. Eligible individuals (HIV-positive, aged 10 years or older, and not taking ART) identified during community-based HIV testing campaigns are offered same-day home-based ART initiation. The intervention clusters offer a differentiated ART delivery package with two features: (1) drug refills and follow-ups by trained and supervised village health workers (VHWs) and (2) the option of receiving individually tailored adherence reminders and notifications of viral load results via SMS. The control clusters will continue to receive standard care, i.e., collecting ART refills from a clinic and no SMS notifications. The primary endpoint is viral suppression 12 months after enrolment. Secondary endpoints include linkage to and engagement in care. Furthermore, safety and cost-effectiveness analyses plus qualitative research are planned. The minimum target sample size is 262 participants. The statistical analyses will follow the CONSORT guidelines. The VIBRA trial is linked to another trial, the HOSENG (HOme-based SElf-testiNG) trial, both of which are within the GET ON (GETing tOwards Ninety) research project.

DISCUSSION

The VIBRA trial is among the first to evaluate the delivery of ART by VHWs immediately after ART initiation. It assesses the entire HIV care cascade from testing to viral suppression. As most countries in sub-Saharan Africa have cadres like the VHW program in Lesotho, this model-if shown to be effective-has the potential to be scaled up. The system impact evaluation will provide valuable cost estimations, and the qualitative research will suggest how the model could be further modified to optimize its impact.

A description of community-based participatory research of hypertension awareness, prevention and treatment in a district of Matabeleland South Province, Zimbabwe

BACKGROUND

 Hypertension is an important worldwide public health challenge because of its high prevalence and concomitant risks of cardiovascular and kidney diseases. The risk factors for hypertension are well known, and screening, diagnosis and treatment of hypertension have been well researched. However, this knowledge has not been translated into community practice as there remains a huge knowledge gap between the academics, health workers and the communities. There is need for community participation in developing and implementation of health interventions among marginalised communities.

AIM

 The aim of this project was to improve the community's knowledge about hypertension by positively influencing beliefs and behaviours, leading to improved community hypertension outcomes.

SETTING

 The study was undertaken in Ward 14, a rural area situated south-west of Gwanda District, Matebeleland South Province in Zimbabwe.

METHODS

 We conducted a health services research utilising qualitative methods by using a community-based participatory approach using a cooperative inquiry group.

RESULTS

 There was improvement in knowledge about awareness and primary prevention of hypertension. Community hypertension care was established through competence training of village health workers (VHWs) and more persons living with hypertension were enrolled into care. Pill pickup rate and treatment compliance improved and the community's confidence in VHWs was restored. Community hypertension screening, treatment registers and health facility referrals were established.

CONCLUSION

 The community was empowered; the VHW was established as a key link between the community and the formal health delivery. This was a sustainable form of improving community hypertension health outcomes.

Integrating community mental health within primary care in southern Malawi: a pilot educational intervention to enhance the role of health surveillance assistants

BACKGROUND

In response to the significant contribution of mental health problems to the global burden of disease, the World Health Organization (WHO, 2008) renewed its call for the integration of mental health services within primary care. The operationalization of this within resource-constrained settings such as rural Malawi, however, presents a challenge, not least the cultural acceptance of approaches to responding to psychological distress.

AIM

This study reports on the development, implementation and evaluation of a mental health care training programme for 271 health surveillance assistants (HSAs) designed to overcome such challenges.

METHOD

A structured evaluation of the impact of training on HSAs' provision of mental health care was undertaken.

RESULTS

Result's demonstrated a statistically significant positive effect on HSAs' knowledge and confidence in providing care and analysis of patient records revealed considerable mental health care and health promotion activity wherein HSAs initiated a new dialogue with the community on mental health and human rights concerns.

CONCLUSION

The HSAs' focus on the psychosocial concerns of individuals' 'distress' and 'risk' prepared the way for a practical set of culturally sensitive and therapeutic interventions and offers a potential path towards increasing the capacity of primary care mental health provision that is responsive to local understandings and experiences of distress.
