Participant Flow

The research team recruited registered and licensed small drug shops, referred to as DLDMs (duka la dawa muhimu), operating in the Mwanza and Shinyanga regions of Tanzania in the Lake Victoria Zone. The results include data collected from August 2022 through December 2023 from 41 wards and 157 DLDMs. Adolescent girls and young women (AGYW) were not enrolled as study participants. AGYW were only recipients of services provided through participating drug shops.

The research team randomized 152 DLDMs in 41 wards. To account for loss to follow-up, the research team added additional shops, resulting in a final analysis sample of 157 DLDMs. For the baseline characteristics, the research team interviewed one pharmacist per facility.

Measure
Intervention
DLDMs in wards randomized to the intervention received the following intervention components: 1. Training on the Maisha Meds point-of-sale electronic inventory system to be used to record sales as well as continuous customer service support; 2. Training on how to use HIVST kits and training on how to provide "girl-friendly" care, including contraceptive counseling; 3. Linkage with 1-2 peer navigators and 1 study-affiliated health facility nurse or caregiver to provide Malkia Klabu members with referrals for care outside the breadth of DLDM care (i.e., injectable contraceptives, STI testing, PrEP); 4. All study-related commodities, including HIVST kits affixed with information for the local study-affiliated public health facility for confirmatory testing or PrEP in addition to the referral contacts; two sequin bags for the prizes; club membership cards; prizes for the prize bags; two tablets (one for inventory, one for young women engagement); and product displays. Shops were required to procure the other study-related products of interest (contraceptives, UPTs) per business-as-usual; and 5. Biweekly reimbursement for sales of products to Malkia Klabu members recorded in Maisha Meds at a set wholesale price.
Standard of Care
DLDMs in wards randomized to the control arm received the same training on Maisha Meds and HIVST kits as well as a monthly supply of HIVST kits for distribution to young women only, with a "Free for young women" sticker affixed and referral information for the local public health facility affixed for confirmatory testing. Other sexual health products were sold as per normal business operations and no reimbursements were provided for sales to young women. Restocking of HIVST kits was contingent upon recorded HIVST kit distribution to young women.

PRIMARY outcome

Timeframe: 12-15 months

Population: While the study intended to collect data for 24 months, unanticipated changes to Tanzania's government oversight structure led to the premature termination of the trial in January 2024. Access to the participant data ended when the trial was terminated. Approval to access the data required for this outcome measure was not granted before termination and will not be granted in the future. Therefore, no data were collected for this outcome measure.

Timeframe: 12-15 months

Distribution of HIV self-test kits (HIVST) to adolescent girls and young women (AGYW) will be documented in Maisha Meds, a point of sales inventory system to be used by participating drug shops in both arms. This will be a continuous variable with a lower limit of zero and an undefined upper limit and is the simple count of all HIVSTs distributed to AGYW who visit the shops.

Self-reported data from adolescent girls and young women (AGYW) on exposure to Malkia Klabu (if any) will be collected during an endline survey. This will be a proportion defined as the number of AGYW who report ever receiving a Malkia Klabu card (i.e. enrolling) as the numerator over the total number of AGYW interviewed. The values will range from 0-100%.

Self-reported data from adolescent girls and young women (AGYW) on contraceptive preferences, desires, and use (if any) will be collected during an endline survey. Unmet need is defined as the number of women who do not want to get pregnant but are not using a method of birth control and are sexually active. We will use the collected data to create a variable where the numerator is the number of women not using a method of birth control and do not desire to get pregnant over the total number of sexually active women.
