A Field Experiment to Assess the Demand for HIV Self-Tests in Zimbabwe

Status Completed

Clinical Trial Summary

This study is a field experiment in peri-urban and rural communities near Harare, Zimbabwe, that seeks to estimate the likelihood that individuals will purchase HIV self-tests under various pricing and distribution strategies. About 4,000 adults will be randomly selected, administered a short questionnaire, and given vouchers that will offer them HIV self-tests at randomly allocated prices and distribution sites. The study will also test whether the provision of HIV self-tests can be targeted more cost-effectively to reach high-risk persons and non- recent testers. Last, the study will explore whether demand for repeated HIV self-testing is contingent on the price offered initially.

Clinical Trial Description

This study is a field experiment that seeks to obtain "revealed preference" estimates of the likelihood that individuals will purchase oral fluid-based HIV self-tests at alternative prices. Such an approach is useful for estimating the price sensitivity (or elasticity) of demand for HIV self-tests. The study will also estimate the extent to which demand for self-tests differs by certain distribution channels such as retail outlets, public sector health facilities, and other community-based venues. Importantly, the experiment will also test whether the provision of HIV self-tests can be targeted more cost-effectively to reach high-risk persons and non-recent testers by examining the demand for self-tests in these populations in responses to various prices and distribution strategies. The results of the study will provide vital information required by policy makers and implementers on the optical pricing and distribution strategies for introducing HIV self-tests and scaling up HIVST in resource-limited settings. In a subsequent study with additional funding, the study will also seek to determine the long-term implications of offering self-tests at very low prices initially; specifically, it will assess whether free distribution initially suppresses individuals' willingness to pay for self-tests in the future. Roughly 12 months after the initial voucher offer, participants who provided a mobile phone number they can access within their household will be contacted via phone-based text messages and offered the same HIV self-tests again at one common non-zero price. The purchases at 12 months will once again be monitored and linked to participants via a unique identifier that is included in the text messages. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
