A groundbreaking pilot study has revealed that vending machines offering self-test kits for sexually transmitted infections (STIs) are a successful and well-received method of reaching individuals who rarely or never undergo testing. The findings, published in the journal Sexually Transmitted Infections, suggest that these vending machines could be integrated into the digital landscape of sexual health services, pending further research to identify optimal locations ensuring privacy and safety.
The year-long pilot involved 11 publicly accessible vending machines placed at seven sites in Brighton and Hove and four in Bristol from April 2022 to March 2023. These machines dispensed rapid HIV tests and self-sampling kits for various STIs. Over the course of the pilot, 2,536 kits were dispensed, with 208 users providing feedback through questionnaires.
The results indicated that self-sample kits for STIs were the most popular, accounting for 74% of vends, with a majority (78%) going to individuals aged 16 to 35. Notably, 68% of users had not tested for STIs in the past 12 months, and 59% had never tested. While 51% of the kits were returned by post, concerns about safety and privacy were raised by 42% and 66% of respondents, respectively.
Convenience, immediate access, and enhanced confidentiality were identified as the primary reasons for utilizing the vending machines. A significant 92% of respondents found the machines user-friendly, and an overwhelming 97% expressed willingness to recommend the service. However, the study highlighted the need for further investigation into privacy and safety considerations when using these machines, along with a comprehensive economic evaluation to determine their cost-effectiveness in reducing demand on clinics and enhancing overall service provision.
The potential applications of these vending machines extend beyond STI testing, as the researchers suggest they could also be used for the delivery of other sexual health services, such as contraception and pre-exposure prophylaxis, in both higher and lower-income settings.
