Does internet-accessed STI (e-STI) testing increase testing uptake for chlamydia and other STIs among a young population who have never tested? Secondary analyses of data from a randomised controlled trial.

Uptake of STI testing among 'never testers' almost doubled. At 6 weeks, 45.3% of the intervention completed at least one test (chlamydia, gonorrhoea, syphilis and HIV), compared with 24.1% of the control (relative risk [RR] 1.88, 95% CI 1.47 to 2.40, p<0.001). For chlamydia and gonorrhoea testing combined, uptake was 44.3% in the intervention versus 24.1% in controls (RR 1.84, 95% CI 1.44 to 2.36, p<0.001). The intervention reduced time to any STI test (restricted mean survival time: 29.0 days vs 36.3 days, p<0.001) at a time horizon of 42 days. CONCLUSIONS : e-STI testing increased uptake of STI testing and reduced time to test among a young population of 'never testers' recruited in community settings. Although encouraging, questions remain on how best to manage the additional demand generated by e-STI testing in a challenging funding environment. Larger studies are required to assess the effects later in the cascade of care, including STI diagnoses and cases treated.
