Biomedical technologies in context
Novel point-of-care tools tailored to contextual needs are critical for improving sexually transmitted infection (STI) management. The genital inflammation test (GIFT) is a point-of-care test under development to detect genital inflammation. A potential use of GIFT is as a screening tool to identify asymptomatic women who may have a sexually transmitted infection (STI) or bacterial vaginosis (BV), followed by confirmatory STI- testing if GIFT-pos…
I can get all the services I want, without fear of being judged ’
Sexual and reproductive health (SRH) services often do not appeal to youth, leading to limited engagement and poor outcomes. We co-designed a community-based integrated HIV and SRH service with and for youth (16-24 years) in Zimbabwe (CHIEDZA) and investigated its acceptability. Qualitative data from observations of CHIEDZA services ( n = 58), and in-depth interviews with healthcare providers ( n = 51), mobilisers ( n = 23), and clients ( n = 63)…
Acceptability and effectiveness of a study information video in improving the research consent process for youth
INTRODUCTION: Obtaining informed consent for research includes the use of information sheets, which are often long and may be difficult for participants to understand. We conducted a trial to investigate whether consent procedures using a study information video coupled with electronic consent were non-inferior to standard consent procedures using participant information sheets (PIS) among youth aged 18-24 years in Zimbabwe. METHODS: The trial wa…
Integrating point-of-care screening for curable sexually transmitted infections with HIV, syphilis and hepatitis B screening in antenatal care services in Zimbabwe
Introduction Sexually transmitted infections (STIs) in pregnancy are associated with adverse birth outcomes. We investigated the uptake and yield of point-of-care screening for Chlamydia trachomatis , Neisseria gonorrhoeae and Trichomonas vaginalis , integrated with HIV, syphilis and hepatitis B virus (HBV) screening in antenatal care (ANC) in Zimbabwe, and conducted a mixed-methods process evaluation of the strategy. Methods A prospective interv…
Evaluation of a novel point-of-care lateral flow assay screening for Neisseria gonorrhoeae infection among pregnant women in Zimbabwe
Affordable, easy-to-use and rapid diagnostics may support a move away from syndromic management for sexually transmitted infections (STIs) in resource-constrained settings. A lateral flow assay for Neisseria gonorrhoeae (NG-LFA) has shown high sensitivity and specificity (>90%) in symptomatic individuals. We investigated the performance and acceptability of this assay as a screening tool for NG among pregnant women. This evaluation was embedded w…
How and why do young people engage in STI screening, treatment, and partner notification? A qualitative positive deviance study in Zimbabwe
Young people have a high burden of sexually transmitted infections (STIs) but low uptake of and high attrition from services. We adopted a positive deviance approach to explore uptake of STI screening, treatment, and partner notification within a sexual and reproductive health service. We conducted in-depth interviews with young people (aged 16-24 years) who accepted screening, treatment, and partner notification slips ( n = 15), and healthcare p…
Differentiated care for youth in Zimbabwe
Youth living with HIV are at higher risk than adults of disengaging from HIV care. Differentiated models of care such as community delivery of antiretroviral therapy (ART) may improve treatment outcomes. We investigated outcomes across the HIV cascade among youth accessing HIV services in a community-based setting. This study was nested in a cluster-randomised controlled trial (CHIEDZA: Clinicaltrials.gov, Registration Number: NCT03719521) conduc…
How to (or how not to) implement crowdsourcing for the development of health interventions
Crowdsourcing strategies are useful in the development of public health interventions. Crowdsourcing engages end users in a co-creation process through challenge contests, designathons or online collaborations. Drawing on our experience of crowdsourcing in four African countries, we provide guidance on designing crowdsourcing strategies across seven steps: deciding on the type of crowdsourcing strategy, convening a steering committee, developing …
Fertility preservation and protection
The study explored social and health system influences on young women's decision-making about family planning in a community setting with low uptake. Seventy-two semi-structured interviews were conducted between April 2020 and November 2021, with both young women accessing, and healthcare workers providing, a community-based integrated package of HIV and sexual and reproductive health services (CHIEDZA) in Zimbabwe. Data were thematically analyse…
Are concepts of adolescence from the Global North appropriate for Africa? A debate
Adolescence is widely defined as a distinct phase in the life-course during which an individual completes their biological development and transitions from childhood to adulthood. This article presents a debate, conducted in 2018 at a scientific symposium in Mwanza, Tanzania, of the appropriateness of this for Africa, and by extension whether health interventions and global health policy that are shaped by such concepts can be universally applica…
Addressing sociodemographic disparities in Covid-19 vaccine uptake among youth in Zimbabwe
INTRODUCTION: COVID-19 vaccine acceptance research has mostly originated from high-income countries and reasons why youth may not get vaccinated may differ in low-income settings. Understanding vaccination coverage across different population groups and the sociocultural influences in healthcare delivery is important to inform targeted vaccination campaigns. METHODS: A population-based survey was conducted in 24 communities across three provinces…
Interrupted Access to and Use of Family Planning Among Youth in a Community‐Based Service in Zimbabwe During the First Year of the Covid‐19 Pandemic
The COVID‐19 pandemic has had serious impacts on economic, social, and health systems, and fragile public health systems have become overburdened in many countries, exacerbating existing service delivery challenges. This study describes the impact of the COVID‐19 pandemic on family planning services within a community‐based integrated HIV and sexual and reproductive health intervention for youth aged 16–24 years being trialled in Zimbabwe (CHIEDZ…
Adolescents’ and caregivers’ perceptions of caregiver-provided testing and HIV self-testing using oral mucosal transudate tests in Zimbabwe
Uptake of HIV testing remains lower among children and adolescents compared to adults. This study explored adolescents' perceptions of HIV self-testing (HIVST) and caregivers' perceptions of testing their children using an oral mucosal transudate (OMT) rapid HIV test (caregiver-provided testing). We conducted 31 interviews with adolescents aged 16-18 years and caregivers of children aged 2-15 years who received an OMT test. Participants described…
“It is not possible to go inside and have a discussion”
Caregivers mediate children's access to HIV care and their adherence to treatment. Support for caregivers may improve health outcomes in children, but fear of HIV stigma and discrimination can affect both uptake and delivery of support services. Within a trial evaluating community-based support for caregivers of newly HIV diagnosed children in Harare, Zimbabwe, we conducted a longitudinal qualitative study to explore how stigma affected delivery …
Familial silence surrounding HIV and non-disclosure of HIV status to older children and adolescents
Increasing numbers of children with HIV are surviving to adolescence and beyond, many of whom are orphaned. Disclosure of childrens' and adolescents' HIV status has been shown to improve adherence and retention in HIV treatment programmes. We investigated caregiving arrangements and intra-familial experience of HIV and its relationship to HIV disclosure to older children and adolescents. Children aged 6-15 years, newly diagnosed with HIV infectio…
The role of community health workers in improving HIV treatment outcomes in children
Reliance on community health workers (CHWs) for HIV care continues to increase, particularly in resource-limited settings. CHWs can improve HIV service use and adherence to treatment, but effectiveness of these programmes relies on providing an enabling work environment for CHWs, including reasonable workload, supportive supervision and adequate training and supplies. Although criteria for effective CHW programmes have been identified, these have…
