Plain English Summary

Background and study aims
The London boroughs of Southwark and Lambeth have some of the highest rates of sexually transmitted infections (STIs) in England. Current face-to-face clinical services are unable to meet demand for sexual healthcare. Sexual Health 24 (SH:24) is an innovative internet-based sexual health service that aims to improve access to sexual healthcare in Lambeth and Southwark. We want to see whether this service can reduce the number of people diagnosed with at least one STI and increase the number of people asking to be tested for such an infection.

Who can participate?
Participants can be of either sex, aged between 16-30 and resident in the boroughs of Lambeth and Southwark. They must be sexually active (at least one partner in the last 12 months), have access to the internet and willing to take an STI test.

What does the study involve?
Participants are randomly allocated to one of two groups. Those in group 1 (intervention group) are given access to the Sexual Health 24 website offering postal STI kits, test results via text message or by phone (HIV only) and details of local treatment clinics. Those in group 2 (control group) are given access to a website with details of local sexual health clinics where participants can get an STI test in person. Six weeks into the study, the number of participants diagnosed with at least one STI and complete at least one STI test in each group are compared.

What are the possible benefits and risks of participating?
Some participants may find this study helpful, particularly if they have been considering taking an STI test. Undetected cases will be diagnosed by those who follow through with the test, and infected participants will be signposted to treatment. It is possible that participants that do not have much privacy at home may risk possible consequences if they participate in internet-based STI testing. However, this risk will be minimised as we will ensure at recruitment that participants have sufficient privacy to participate in the study.

Where is the study run from?
1. King's College Hospital NHS Foundation Trust (UK)
2. Guy's and St Thomas' Hospital NHS Foundation Trust (UK)

When is the study starting and how long is it expected to run for?
