The use of PrEP among men who have sex with men and transgender women as Biomedical Prevention Work: A conceptual framework

Based on ethnographic fieldwork among men who have sex with men and transgender women in Tanzania, this article explores the various types of work that may go into enrolment into PrEP programming and using pre-exposure prophylaxis (PrEP). PrEP protects against HIV acquisition and is widely touted as an essential tool in 'ending AIDS by 2030'. While taking PrEP has often been portrayed as 'just taking a pill a day' in public health campaigns, a striking observation during fieldwork was that enrolling in PrEP programming and adhering to PrEP involved a wide range of tasks. Inspired by this fieldwork experience and the literature on sociology of work, more specifically illness work and patient work, we started to think of these tasks as work. This paper identifies the range of tasks that PrEP users in Dar es Salaam had to perform as part of their enrolment and usage of PrEP. We provide a description of these tasks, organised into three categories of work that we refer to as (a) readying work, (b) user work, and (c) social navigation work that jointly make up what we propose to call biomedical prevention work. We further suggest that this analytical framework can be applicable to other biomedical prevention methods in other contexts.

Development of a Mobile Health Application for HIV Prevention Among At-Risk Populations in Urban Settings in East Africa: A Participatory Design Approach

Background

There is limited evidence in Africa on the design and development of mobile health (mHealth) applications to guide best practices and ensure effectiveness. A pragmatic trial for HIV pre-exposure prophylaxis roll-out among key populations in Tanzania is needed.

Objective

We present the results of the development of a mobile app (Jichunge) intended to promote adherence to pre-exposure prophylaxis (PrEP) among men who have sex with men (MSM) and female sex workers (FSW) in Tanzania.

Methods

A participatory design approach was employed and guided by the information system research framework. MSM and FSW were the target populations. A total of 15 MSM and 15 FSW were engaged in the relevance and design cycles, while the piloting phase included 10 MSM and 20 FSW.

Results

The relevance cycle enabled the description of the existing problem, provided the compatible app features for the target population, and identified the need to develop an mHealth app that provides health services in a stigmatizing and discriminating environment. User involvement in the app’s design and evaluation provided an opportunity to incorporate social, cultural, and community-specific features that ensured usability. In addition, the participants suggested valuable information to inform the app, text message services, medication registration, and chat platform designs.

Conclusions

The participatory design approach in the development of mHealth apps is useful in identifying and validating population-specific functional features, improve usability, and ensuring future health impacts. Through this participatory process, the Jichunge app took end-user needs, perspectives, and experiences into account, eliciting enthusiasm regarding its potential role in supporting pre-exposure prophylaxis adherence for HIV and related behavioral change promotion.
