(P260) Survey : Characteristics of an Ideal STI Anonymous Partner Notification app for French MSM on PrEP - KYSS – Know Your Status

Background: Partner Notification (PN) is a major component of Sexually Transmitted Infections (STI) control, but it is difficult. Tools for Anonymous Partner Notification (APN) by SMS exist. Dating apps make anonymous sexual encounters easy; it is a limitation for SMS notification tools, especially in parties or sex places where exchanging phone numbers can be cumbersome. Logging an encounter via another anonymous way (QR code, bump, swipe…) and being able, in case of an STI diagnosis, to send out a notification without using a phone number would alleviate this limitation. This can be adapted to parties and sex places: registering anonymously everyone’s presence so anyone logged at the same place and time would receive a notification in case someone sent out one. This is the concept of the app KYSS – Know Your StatuS© (KYSS). We conducted a preliminary implementation study among French MSM on PrEP to assess their interest and needs for such app.

Methods: An anonymous survey was offered to MSM on PrEP in a private practice and free STI clinics in Paris region and in Martinique, presented at the end of a consultation or via email, between July and August 2022 and between November 2022 and January 2023.



Results: 220 people took the survey. 207/220 (94%) thought an APN app would be interesting. PN in the context of private parties or sex places was difficult for 149/220 (68%) - it didn't apply to 65/220 (30%). Scanning a QR code, swiping or bumping phones before or after sex, at the door of a private party was “possible” or “easy” for 184/220 (83%). The main characteristics expected for an ideal APN app were simplicity, anonymity, discretion.





Conclusion: KYSS concept matches French MSM on PrEP expectations for an ideal APN app. It would fill a gap in the control strategy by offering for the first time a solution for group sex in private or commercial settings. The funding, development and launch of such an app are necessary so it is available to those who need it. In addition to direct PN, anonymous text PN and assisted PN, KYSS would participate in a better control of STIs.
