Development, Implementation, and Scale Up of the National Furaha Yangu Campaign to Promote HIV Test and Treat Services Uptake Among Men in Tanzania

State of the Science of Scale-Up of Cancer Prevention and Early Detection Interventions in Low- and Middle-Income Countries: A Scoping Review

PURPOSE

Cancer deaths in low- and middle-income countries (LMICs) will nearly double by 2040. Available evidence-based interventions (EBIs) for cancer prevention and early detection can reduce cancer-related mortality, yet there is a lack of evidence on effectively scaling these EBIs in LMIC settings.

METHODS

We conducted a scoping review to identify published literature from six databases between 2012 and 2022 that described efforts for scaling cancer prevention and early detection EBIs in LMICs. Included studies met one of two definitions of scale-up: (1) deliberate efforts to increase the impact of effective intervention to benefit more people or (2) an intervention shown to be efficacious on a small scale expanded under real-world conditions to reach a greater proportion of eligible population. Study characteristics, including EBIs, implementation strategies, and outcomes used, were summarized using frameworks from the field of implementation science.

RESULTS

This search yielded 3,076 abstracts, with 24 studies eligible for inclusion. Included studies focused on a number of cancer sites including cervical (67%), breast (13%), breast and cervical (13%), liver (4%), and colon (4%). Commonly reported scale-up strategies included developing stakeholder inter-relationships, training and education, and changing infrastructure. Barriers to scale-up were reported at individual, health facility, and community levels. Few studies reported applying conceptual frameworks to guide strategy selection and evaluation.

CONCLUSION

Although there were relatively few published reports, this scoping review offers insight into the approaches used by LMICs to scale up cancer EBIs, including common strategies and barriers. More importantly, it illustrates the urgent need to fill gaps in research to guide best practices for bringing the implementation of cancer EBIs to scale in LMICs.

Decolonizing a Wretched Healthcare System: The African Public Health Practitioner Case

Introduction

Over the past two years, public health practitioners in African countries have worked actively to combat the Coronavirus Disease 2019 (COVID-19) pandemic with relatively low fatality rates. This pandemic has forced healthcare professionals to re-think and redesign the healthcare system within their own country.

Methods

Using the Afrocentric PEN-3 framework and a letter style, the purpose of this commentary was to describe the positive, existential, and negative socio-cultural values associated with African healthcare systems. The commentary also highlights socio-cultural factors affecting public trust in African healthcare systems and their health agencies and how systematically decolonizing them may decrease foreign reliance and empower efficient locally based solutions.

Results

We, as African public health practitioners, make three key points in this commentary. First, African public health practitioners have developed resilience within under-resourced healthcare systems. Secondly, oral tradition in African societies and its byproduct (social media) is the means through which people connect and share what they know about any topics (COVID-19). Thirdly, African leaders have particularly contributed to the high level of distrust in their countries' healthcare systems in favor of the healthcare systems of industrialized countries.

Conclusion

This commentary concludes with implications for encouraging African public health practitioners to cultivate the resilience that has led to contributing to the wellness of millions of Africans during this COVID-19 pandemic.

Peer-based Promotion and Nurse-led Distribution of HIV Self-Testing Among Networks of Men in Dar es Salaam, Tanzania: Development and Feasibility Results of the STEP Intervention

Background

According to the 2016-2017 Tanzania HIV Impact Survey, only 45% of men living with HIV (MLWH) were aware of their HIV status. In an effort to increase HIV testing in Tanzania, including among men, the Government of Tanzania passed a law in December 2019 to allowing HIV self-testing (HIVST) to be included in the national testing strategies. The objective of this paper is to describe the development and pilot feasibility assessment of the Self-Testing Education and Promotion (STEP) intervention, which was one of the projects conducted in Tanzania focusing on men to inform policy change.

Methods

The development and piloting processes were guided by the ADAPT-ITT model and informed by a national PEPFAR/USAID-funded HIV implementation science project called Sauti.The adapted STEP intervention included the following two components: 1) peer-based HIVST promotion; and 2) nurse-led HIVST distribution. For the feasibility assessment, 25 men were selected and trained to promote HIVST among their peers before helping to recruit 253 men to receive instructions and collect an HIVST kit from a nurse at a community-based study tent site.

Results

Of the 236 participants who completed the 1-month follow-up survey, 98.3% reported using the kit. The majority (92.4%) of participants reported a negative HIVST result while 4.2% (n=10) received a positive result. Most (70%, n=7) of the participants with a positive result sought follow-up services at a healthcare facility while 40.3% (n=95) of the participants with a negative self-test result visited the community-based project site. Most of the men (53%, n =129) did not visit a healthcare facility or the study site. The majority of participants reported having a mobile phone and forty-seven of them called someone to share their results while twenty-seven sent a text message about their results.

Conclusion

The findings demonstrate that the combined peer-based promotion and nurse-led distribution of HIVST intervention in the community for men was acceptable and feasible. However, the high proportion of men who visited the tent site in the community after self-testing indicated that future research should evaluate the potential for nurses to provide community-based linkage to HIV care and prevention services for self-testers.

HIV Prevalence among Injury Patients Compared to Other High-Risk Groups in Tanzania

Sixty-eight percent of persons infected with HIV live in Africa, but as few as 67% of those know their infection status. The emergency department (ED) might be a critical access point to HIV testing. This study sought to measure and compare HIV prevalence in an ED injury population with other clinical and nonclinical populations across Tanzania. Adults (≥18 years) presenting to Kilimanjaro Christian Medical Center ED with acute injury of any severity were enrolled in a trauma registry. A systematic review and meta-analysis was conducted to compare HIV prevalence in the trauma registry with other population groups. Further, 759 injury patients were enrolled in the registry; 78.6% were men and 68.2% consented to HIV counseling and testing. The HIV prevalence was 5.02% (tested), 6.25% (self-report), and 5.31% (both). The systematic review identified 79 eligible studies reporting HIV prevalence (tested) in 33 clinical and 12 nonclinical population groups. Notable groups included ED injury patients (3.53%, 95% CI), multiple injury patients (10.67%, 95% CI), and people who inject drugs (17.43%, 95% CI). These findings suggest that ED injury patients might be at higher HIV risk compared to the general population, and the ED is a potential avenue to increasing HIV testing among young adults, particularly men.
