Adult South African men preferences for HIV pre-exposure prophylaxis (PrEP): A discrete choice experiment comparing long acting injectable versus daily oral tablet

The pending approval of long-acting injectable (LAI) pre-exposureprophylaxis (PrEP) in South Africa (SA) has the potential to significantly change the biomedical HIV prevention space which currently relies heavily on daily, oral PrEP. Prior to the rollout of LAI in SA, it is important to understand what attributes of each modality and its delivery are likely to influence decision making amongst underserved populations such as sexually active adult 

“I didn’t understand well” – COVID-19 vaccine and booster misconceptions among the general population and people living with HIV in South Africa

Overcoming vaccine hesitancy and enhancing vaccine uptake is a critical public health priority. Research on knowledge and beliefs about COVID-19 vaccines in South Africa can be useful for developing messages that utilize behavioural economics (BE) insights and effectively counter misconceptions. Such an approach could also be applied to future HIV vaccine campaigns. 

Nudging men towards voluntary medical male circumcision: A quasi-experimental study in South Africa of four interventions using behavioural economics insights to increase demand for circumcision

While voluntary medical male circumcision (VMMC) has great potential to reduce HIV incidence, demand for VMMC in South Africa is below global and national targets. We evaluated the impact of four online VMMC recruitment forms, designed using behavioural economics insights, on men signing up for VMMC using the data free mobile App, 

Rapid learning to inform behavioural interventions for HIV programmes – Lessons from Indlela’s Behavioural Hub (B-Hub)

Behavioural economics holds enormous potential as a discipline that can suggest cost-effective interventions to address various public health challenges. To realize this potential, we created a Behavioural Hub (B-Hub), a group of individuals (potential clinic attendees, clinic attendees, clinic staff) who consent to provide ongoing feedback on intervention designs, complete rapid surveys, participate in A/B testing of prototypes, and offer contextual input on HIV service delivery 

Applying behavioural economics principles to increase demand for free HIV Testing Services at private General Practitioners in Johannesburg, South Africa

Expanding free HIV testing service (HTS) access to include private general practitioners (GP) could potentially increase testing rates. GPs from the GP Care Cell project make limited investments in creating demand for HIV testing. We investigated whether HTS demand creation materials that used behavioural economics principles (BE) could increase demand for HIV testing at GP 

Evaluating the acceptability and appropriateness of the B-OK bead bottles and their effect on ART knowledge and attitudes among people living with HIV in KwaZulu Natal province, South Africa

Effective health communication is important for promoting ART adherence. The B-OK bead bottles are a simple visual aid designed to help healthcare workers explain complex HIV concepts. During counselling sessions with PLHIV in KwaZulu-Natal, South Africa, we assessed the acceptability and appropriateness of using the B-OK tool as well as its effect on knowledge and 

Healthcare provider preferences for TB preventive therapy regimens in two provinces in South Africa

28 in-depth interviews (IDIs) with health care providers (HCPs) were conducted between April-December 2022. We used purposive sampling to recruit doctors, pharmacists, and nurses in 8 TB and/or HIV facilities in the City of Johannesburg Metropolitan Municipality (COJ), Gauteng, and 6 facilities in Greater Tzaneen, Limpopo Province. IDIs were recorded for quality, transcription, and translation purposes. HCPs ranked 3 hypothetical TPT regimens from “best to worst”, and then ranked specific 

Understanding barriers and facilitators to HIV care for women aged 30-49 years: An exploratory study in Gauteng and Limpopo, South Africa

The HIV epidemic in Sub-Saharan Africa has a disproportionate gender impact, with women bearing the brunt of the epidemic. South Africa carries the largest share of the global HIV burden, with similar trends seen for women due to unequal socio-cultural and economic status. This study aims to understand 30-49 year old women’s barriers and facilitators to accessing HIV services in order to maximize health in resource limited settings and reach women missing from HIV 

Cost-effectiveness of the optimal mix of differentiated service delivery models for HIV treatment in Zambia: a mathematical modelling study

Background Any countries in sub-Saharan Africa have rapidly scaled up differentiated service delivery (DSD) models for HIV treatment to provide more client-centric care and manage high numbers of clients on lifetime ART.  In most countries, DSD models evolved organically based on the availability of infrastructure, staffing, and other resources in hand and on international recommendations.  As a result, the current mix of models in use may or may not be optimal, in terms of 

Evaluating the effect of dynamic changes in risk profile on subsequent interruption in HIV treatment: A threshold approach to risk triaging

The HIV care journey Continuity of HIV care is critical yet challenging, especially in the early treatment period RETAIN6: Models of care for the first six months of HIV treatment Optimize service delivery during the “early treatment” period About half of initiating clients experience an interruption in treatment during the first 12 months on
