✪ Strengthening primary care facility management: a systematic review of management interventions, implementation strategies, and outcomes in six sub-Saharan African countries

Abstract:

Background

Although primary health care (PHC) is central to health system performance, effective facility-level management is a critical determinant of service quality, resource use, and improved health outcomes. We conducted a systematic review to synthesize evidence on interventions, implementation strategies, and outcomes aimed at strengthening PHC facility management in Sub-Saharan Africa (SSA).

Methods

We conducted a systematic review using thematic synthesis. Eight electronic databases were searched for peer-reviewed studies and grey literature published between 2012 and 2022, focusing on interventions targeting PHC facility management in SSA. Implementation strategies were mapped to the thematic cluster areas of the Expert Recommendations for Implementing Change (ERIC) framework. Implementation outcomes were classified using Proctor’s Implementation Outcome Framework, and management effectiveness domains were identified through thematic analysis.

Results

Of 3,752 studies screened, nine met the inclusion criteria. These studies represented six SSA countries: Botswana, Ethiopia, Kenya, South Africa, Tanzania, and Zambia. Four categories of intervention were identified: (1) training and capacity building programs, (2) peer-to-peer learning, (3) audit and feedback-based quality management systems, and (4) supportive supervision. These interventions were delivered through multiple implementation strategies, including training and education, coaching and mentoring, learning collaboratives, interactive continuous learning, and routine data monitoring. Acceptability was the most consistently reported implementation outcome. Improvements in management effectiveness were identified across four domains: financial management, organizational climate and culture, resource management and utilization, and human resource management. Five studies also reported intermediate service-level outcomes including improvements in maternal and child health indicators.

Conclusion

Interventions aimed at strengthening PHC facility management in SSA primarily emphasize skill development, collaboration, and ongoing managerial support, typically delivered through multiple strategies. However, few studies have evaluated these interventions using rigorous experimental or pragmatic study designs. More robust implementation research is needed to identify effective strategies for strengthening PHC facility management and supporting the consistent implementation of national PHC guidelines.

✪ Acceptability and Feasibility of Remote PrEP Visits for Adolescent Girls and Young Women in South Africa

Abstract:

The World Health Organization recommends differentiated service delivery (DSD) models for HIV prevention, including alternatives to clinic-based PrEP services. This study assessed the acceptability and feasibility of remote PrEP delivery—including HIV and pregnancy self-testing, and phone-based adherence counselling—among adolescent girls and young women (AGYW) in Johannesburg. The research was nested within the PrEP SMART trial (2019–2022), which evaluated scalable adherence support strategies for AGYW aged 18–25. During COVID-19 lockdowns, PrEP refills and testing kits were delivered to participants’ homes, and counselling was provided by phone. Using a phenomenological qualitative method, we conducted in-depth interviews with AGYW (n = 14) who had the option to complete remote PrEP visits (accepting or declining), study staff (n = 12), and key informants (n = 10) involved in PrEP programming. Thematic analysis explored experiences of remote delivery, focusing on acceptability and feasibility.

AGYW found remote PrEP visits convenient, empowering, and time-saving. Procedures such as self-testing and phone counselling were generally acceptable, though some expressed anxiety about performing tests incorrectly and concerns over privacy, stigma, and unintentional disclosure of PrEP use at home. About half still preferred clinic-based visits. Staff and key informants recognized benefits, but highlighted challenges related to cost, sustainability, and provider workload. Suggestions for improvement included integrating contraception and partnering with community organizations. In conclusion, remote PrEP delivery is acceptable and feasible for many AGYW but not universally suitable. These findings support the inclusion of remote PrEP options in DSD models, with attention to privacy concerns and support for self-testing in this age group.

✪ When evidence is not enough: A qualitative exploration of healthcare workers’ perspectives on expansion of two-way texting (2wT) for post- circumcision follow-up in South Africa

Abstract:

As per South African national guidelines, in-person follow-up visits after voluntary medical male circumcision (VMMC) are required but may be unnecessary. Two-way texting (2wT), an mHealth platform, engages clients in post-operative care and triages those with complications to in-person review. 2wT was found to be safe, effective, and efficient. In South Africa, to understand provider perspectives on 2wT and potential for expansion, 20 key informant interviews were conducted with management, clinicians, data officials and support staff involved in 2wT scale-up. Interviews were analyzed using rapid qualitative methods and informed by two implementation science frameworks: the Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM) framework and the Pragmatic, Robust, Implementation and Sustainability Model (PRISM). Participants shared mixed and multi-faceted feedback, including that 2wT improves monitoring and evaluation of clients and clinical outcomes while also reducing follow-up visits. Challenges included duplicative routine and 2wT reporting systems and perceptions that 2wT increased workload. To improve the likelihood of successful 2wT scale-up in routine VMMC settings, participants suggested: further 2wT sensitization to ensure clinician and support staff buy-in; a dedicated clinician or nurse to manage telehealth clients; improved dashboards to better visualize 2wT client data; mobilizing 2wT champions at facilities to garner support for 2wT as routine care; and updating VMMC guidelines to support VMMC telehealth. As attendance at follow-up visits may not be as high as reported, implementing 2wT may require more effort but also brings added benefits of client verification and documented follow-up. The transition from research to routine practice is challenging, but use of RE-AIM and PRISM indicate that it is not impossible. As VMMC funding is decreasing, more effort to share the evidence base for 2wT as a safe, cost-effective, high-quality approach for VMMC follow-up is needed to encourage widespread uptake and adoption.

Author summary

South Africa has a high prevalence of HIV, and voluntary medical male circumcision is a prevention method recommended by the World Health Organization. Two-way texting (2wT) is a digital health intervention that allows males to receive educational messages after circumcision about healing and send messages directly to a provider via SMS or WhatsApp. This system detects as many complications as routine follow-up care, though is more efficient. As we scale up to new locations in South Africa, we wanted to ensure the approach is well-adapted for health workers. Through 20 interviews with health workers, we found that it saves clients in-person visits and helps with data collection. However, more effort is needed to introduce the intervention to clinicians, including providing better training and appointing champions to help motivate clinicians. Funding for HIV and VMMC programs is decreasing, so it is important to find tools such as digital health to reduce the burden on facilities while maintaining quality client care.

✪ Finding the balance between rigour and relevance: implementing adaptations to the implementation of a pragmatic randomised controlled trial of a two-way texting intervention for voluntary medical male circumcision in South Africa

Abstract:

Objectives

To document adaptations that were made to the implementation of the two-way texting (2wT) randomised controlled trial (RCT) for voluntary medical male circumcision (VMMC) in South Africa and to provide a nuanced discussion on the differences between adaptations and fidelity in this context.

Design

We conducted a qualitative study using the Framework for Reporting Adaptations and Modifications in Evidence-based Implementation Strategies (FRAME-IS) to examine 2wT adaptations. We reported adaptations to the 2wT intervention using two steps. First, we categorised adaptations in a shared study-specific Google Docs that documented participant engagement with the 2wT system, tracked daily RCT implementation notes, reported software bugs and noted reminder emails about adaptations for the research team. Second, we conducted a qualitative assessment of the influence of adaptations on project outcomes via 10 periodic reflection meetings with VMMC implementers. Reflection documentation included notes from field observations, meeting minutes and informal partner check-ins to complete adaptation documentation. Using the FRAME-IS as a codebook, adaptations were categorised.

Settings

The RCT was conducted in rural and urban VMMC clinics in the North West and Gauteng districts of South Africa.

Participants

Implementation scientists and VMMC implementers who implemented the 2wT pragmatic randomised controlled trial (pRCT) were participants for the adaptation study.

Primary and secondary outcome measures

The primary outcome measure was the adaptations that were made during the implementation of the 2wT pRCT. The secondary outcome measures were fidelity and rigour of implementing adaptations to the 2wT pRCT.

Results

Between June 2021 and February 2022, 13 adaptations were identified in three phases during the implementation of the 2wT pRCT. The first phase of adaptations aimed to augment study recruitment, including conducting weekend VMMC recruitment camps, using mobile outreach services in the rural site, adding two urban sites to increase recruitment, using weekly WhatsApp calls for updates with all implementing teams, using virtual meetings to implement the 2wT strategy remotely during COVID-19 restrictions and allocating one clinician to work outside of normal working hours. The second phase of adaptations further enhanced enrolments, including adding two local language translations in the usability survey for 2wT men and contributing a portion towards the salary of the implementing staff by the research partner. The third phase included the exclusion of two rural clinics as recruitment sites due to inconsistent mobile phone networks, adding another layer of data quality checks to ensure data quality, training non-clinical counsellors to help with enrolling clients, retraining of staff in the rural site with high staff turnover and using both primary and alternative phone numbers for enrolment to reduce loss to follow-up.

Conclusions

This study made adaptations to the 2wT pRCT without compromising the fidelity of the study. The 2wT pRCT balances rigour (fidelity) and relevance (adaptation). Adaptations should not be confined by rigour but should also not go unchallenged or unverified. We conclude that fidelity can be maintained with adaptations that are implemented to close the gap between research in the laboratory and practice.

✪ Healthcare provider perspectives on integrating HIV care into cancer centers in Malawi, South Africa, Uganda, and Zimbabwe

Abstract:

Background

In East and Southern Africa, treatment of people with concomitant cancer and HIV is complicated by siloed service delivery pathways, which exacerbate barriers to care and impact clinical decision-making. Integrating HIV care into cancer treatment centers may improve service delivery and overall patient outcomes.

Methods

We administered a questionnaire to clinicians and support staff at tertiary cancer referral centers in Malawi, Zimbabwe, Uganda, and South Africa to assess level of concern about clinical management of people with HIV (PWH) and cancer, barriers to integrating HIV service delivery into cancer treatment delivery, and beliefs related to HIV, antiretroviral therapy (ART), and integrated care.

Results

Of 195 clinician and support staff participants, 165 (85 %) were direct providers of cancer-associated care. Over 50 % indicated that they held concerns about survival, treatment complications, co-morbidities, and drug-drug interactions in PWH compared to patients without HIV. Over 80 % agreed that knowing cancer patients’ HIV status, ART status, and ART regimen would facilitate better care and should be considered in cancer care decision-making. Overall, respondents were optimistic that HIV-related care could be easily integrated into cancer care provision. The most-frequently endorsed barriers to integrated care were workspace limitations, disruptions to workflow, availability of staff, and cost to the hospital and to patients.

Conclusions

Cancer clinicians and support staff report overall positive attitudes toward integrating HIV and cancer service delivery. Research to elucidate service delivery pathways and contextualize system-based barriers to integrating care are critical next steps to optimize linked HIV and cancer care delivery.

✪ Training and Support Practices and Insights in the Sustainability of mHealth Implementations in Sub-Saharan Africa

Abstract:

We conducted an interview-based study to understand the training and support practices and insights that influence sustainable implementations of mHealth projects of varying mHealth technologies. The qualitative assessment was inspired by the Consolidated Framework for Implementation Research adapted with the recommended questions for guiding the implementation of training programs. Participants in the study (N = 16) were both international and in-country researchers managing projects in sub-Saharan Africa. We chose to focus on training and support, as it is often the interface between international and in-country components of these projects. Participants agreed on the central role of training in the implementation of mHealth projects and are following best practices. There was often a division in the responsibility of training between international and in-country researchers reflecting the distinction between project management and local implementation adaptions. One of the main findings is the importance of individualized continuous retraining to make deployments robust with respect to changing conditions with technology and personnel, an aspect that has been managed a bit differently with varying mHealth technologies as presented in this article.

✪ WhatsApp Versus SMS for 2-Way, Text-Based Follow-Up After Voluntary Medical Male Circumcision in South Africa: Exploration of Messaging Platform Choice

Abstract:

Background

Telehealth is growing, especially in areas where access to health facilities is difficult. We previously used 2-way texting (2wT) via SMS to improve the quality of postoperative care after voluntary medical male circumcision in South Africa. In this study, we offered males aged 15 years and older WhatsApp or SMS as their message delivery and interaction platform to explore user preferences and behaviors.

Objective

The objectives of this process evaluation embedded within a larger 2wT expansion trial were to (1) explore 2wT client preferences, including client satisfaction, with WhatsApp or SMS; (2) examine response rates (participation) by SMS and WhatsApp; and (3) gather feedback from the 2wT implementation team on the WhatsApp approach.

Methods

Males aged 15 years and older undergoing voluntary medical male circumcision in program sites could choose their follow-up approach, selecting 2wT via SMS or WhatsApp or routine care (in-person postoperative visits). The 2wT system provided 1-way educational messages and an open 2-way communication channel between providers and clients. We analyzed quantitative data from the 2wT database on message delivery platforms (WhatsApp vs SMS), response rates, and user behaviors using chi-square tests, z tests, and t tests. The team conducted short phone calls with WhatsApp and SMS clients about their perceptions of this 2wT platform using a short, structured interview guide. We consider informal reflections from the technical team members on the use of WhatsApp. We applied an implementation science lens using the RE-AIM (reach, effectiveness, adoption, implementation, and maintenance) framework to focus results on practice and policy improvement.

Results

Over a 2-month period—from August to October, 2023—337 males enrolled in 2wT and were offered WhatsApp or SMS and were included in the analysis. For 2wT reach, 177 (53%) participants chose WhatsApp as their platform (P=.38). Mean client age was 30 years, and 253 (75%) participants chose English for automated messages. From quality assurance calls, almost all respondents (87/89, 98%) were happy with the way they were followed up. For effectiveness, on average for the days on which responses were requested, 58 (33%) WhatsApp clients and 44 (28%) SMS clients responded (P=.50). All 2wT team members believed WhatsApp limited the automated message content, language choices, and inclusivity as compared with the SMS-based 2wT approach.

Conclusions

When presented with a choice of 2wT communication platform, clients appear evenly split between SMS and WhatsApp. However, WhatsApp requires a smartphone and data plan, potentially reducing reach at scale. Clients using both platforms responded to 2wT interactive prompts, demonstrating similar effectiveness in engaging clients in follow-up. For telehealth interventions, digital health designers should maintain an SMS-based platform and carefully consider adding WhatsApp as an option for clients, using an implementation science approach to present evidence that guides the best implementation approach for their setting.

✪ Integrating a mental health intervention into PrEP services for South African young women: a human-centered implementation research approach to intervention development

Abstract:

Introduction

Adolescent girls and young women (AGYW) who may benefit from HIV pre-exposure prophylaxis (PrEP) face high levels of common mental disorders (e.g. depression, anxiety). Common mental disorders can reduce PrEP adherence and increase HIV risk, yet mental health interventions have not been well-integrated into PrEP delivery.

Methods

We conducted a four-phase human-centered design process, from December 2020 to April 2022, to understand mental health challenges among AGYW in Johannesburg, South Africa and barriers to integrated mental health and PrEP services. In the “Discover” phase, we conducted in-depth interviews with AGYW and key informants (KIs) in Johannesburg. We conducted a rapid qualitative analysis, informed by the Consolidated Framework for Implementation Research (CFIR), to identify facilitators and barriers of integrated mental health and PrEP services and mapped barriers to potential implementation strategies. In the “Design” and “Build” phases, we conducted stakeholder workshops to iteratively adapt an evidence-based mental health intervention, the Friendship Bench, and refine implementation strategies for South African PrEP delivery settings. In the “Test” phase, we piloted our adapted Friendship Bench package.

Results

Interviews with 70 Discover phase participants (48 AGYW, 22 KIs) revealed the importance of integrated mental health and PrEP services for South African AGYW. Interviewees described barriers and implementation strategies for mental health and PrEP services around the CFIR domains: intervention characteristics (e.g. challenges with AGYW “opening up”); outer Johannesburg setting (e.g. community stigma); inner clinic setting (e.g. judgmental healthcare providers); characteristics of counsellors (e.g. training gaps); and the implementation process (e.g. need for demand creation). The Design and Build workshops included 13 AGYW and 15 KIs. Implementation barriers related to the quality and accessibility of public-sector clinic services, lay counsellor training, and community education and demand creation activities were prioritized. This led to 12 key Friendship Bench adaptations and the specification of 10 implementation strategies that were acceptable and feasible in initial pilot testing with three AGYW.

Conclusions

Using a human-centered approach, we identified determinants and potential solutions for integrating mental health interventions within PrEP services for South African AGYW. This design process centered stakeholders’ perspectives, enabling rapid development of an adapted Friendship Bench intervention implementation package.

✪ Adapting and testing measures of organizational context in primary care clinics in KwaZulu-Natal, South Africa

Abstract:

Background

Implementation science frameworks situate intervention implementation and sustainment within the context of the implementing organization and system. Aspects of organizational context such as leadership have been defined and measured largely within US health care settings characterized by decentralization and individual autonomy. The relevance of these constructs in other settings may be limited by differences like collectivist orientation, resource constraints, and hierarchical power structures. We aimed to adapt measures of organizational context in South African primary care clinics.

Methods

We convened a panel of South African experts in social science and HIV care delivery and presented implementation domains informed by existing frameworks and prior work in South Africa. Based on panel input, we selected contextual domains and adapted candidate items. We conducted cognitive interviews with 25 providers in KwaZulu-Natal Province to refine measures. We then conducted a cross-sectional survey of 16 clinics with 5–20 providers per clinic (N = 186). We assessed reliability using Cronbach’s alpha and calculated interrater agreement (awg) and intraclass correlation coefficient (ICC) at the clinic level. Within clinics with moderate agreement, we calculated correlation of clinic-level measures with each other and with hypothesized predictors – staff continuity and infrastructure – and a clinical outcome, patient retention on antiretroviral therapy.

Results

Panelists emphasized contextual factors; we therefore focused on elements of clinic leadership, stress, cohesion, and collective problem solving (critical consciousness). Cognitive interviews confirmed salience of the domains and improved item clarity. After excluding items related to leaders’ coordination abilities due to missingness and low agreement, all other scales demonstrated individual-level reliability and at least moderate interrater agreement in most facilities. ICC was low for most leadership measures and moderate for others. Measures tended to correlate within facility, and higher stress was significantly correlated with lower staff continuity. Organizational context was generally more positively rated in facilities that showed consistent agreement.

Conclusions

As theorized, organizational context is important in understanding program implementation within the South African health system. Most adapted measures show good reliability at individual and clinic levels. Additional revision of existing frameworks to suit this context and further testing in high and low performing clinics is warranted.

✪ Systems analysis and improvement approach to optimize tuberculosis (SAIA-TB) screening, treatment, and prevention in South Africa: a stepped-wedge cluster randomized trial

Abstract:

Background

The use of systems engineering tools, including the development and use of care cascades using routinely collected data, process mapping, and continuous quality improvement, is used for frontline healthcare workers to devise systems level change. South Africa experiences high rates of tuberculosis (TB) infection and disease as well as HIV co-infection. The Department of Health has made significant gains in HIV services over the last two decades, reaching their set “90–90-90” targets for HIV. However, TB services, although robust, have lagged in comparison for both disease and infection. The Systems Analysis and Improvement Approach (SAIA) is a five-step implementation science method, drawn from systems engineering, to identify, define, and implement workflow modifications using cascade analysis, process mapping, and repeated quality improvement cycles within healthcare facilities.

Methods

This stepped-wedge cluster randomized trial will evaluate the effectiveness of SAIA on TB (SAIA-TB) cascade optimization for patients with TB and high-risk contacts across 16 clinics in four local municipalities in the Sarah Baartman district, Eastern Cape, South Africa. We hypothesize that SAIA-TB implementation will lead to a 20% increase in each of: TB screening, TB preventive treatment initiation, and TB disease treatment initiation during the 18-month intervention period. Focus group discussions and key informant interviews with clinic staff will also be conducted to determine drivers of implementation variability across clinics.

Discussion

This study has the potential to improve TB screening, treatment initiation, and completion for both active disease and preventive measures among individuals with and without HIV in a high burden setting. SAIA-TB provides frontline health care workers with a systems-level view of their care delivery system with the aim of sustainable systems-level improvements.
