Service user experiences of using internet-based testing for sexually transmitted infections (STIs): a qualitative...

Internet-based testing for sexually transmitted infections allows individuals to order a self-sampling kit online, send samples to a central laboratory and receive their results electronically, reducing the need to attend a clinic unless for treatment. Its usage has grown rapidly in many high-income countries, such as England, where it now accounts for 44% of tests within the National Chlamydia Screening Programme. However, there is limited data on the experiences of service users, which may offer insights into low uptake and poor return rates among some high-incidence populations.

Participants were recruited via sexual health clinics and the website of an internet-based testing service. Purposive sampling was used to ensure a diversity of genders, sexualities and ethnic backgrounds were included. Semistructured interviews were conducted by phone, email and messenger services and explored participants' perceptions and experiences of both internet-based and clinic-based testing. Data underwent thematic analysis.

We interviewed 17 participants. Internet-based testing appealed to many due to the privacy and convenience it offered over clinic-based testing. Although most were positive about their experience of internet-based testing, many found the process of finger-prick blood sampling extremely challenging and this contributed to concerns from some participants that test results may be inaccurate. A minority of participants missed the opportunity that clinic-based testing offered to discuss symptoms or concerns with staff. Participants overwhelmingly found the process of receiving test results by short message service (SMS) acceptable and preferable to alternatives.

Internet-based testing is viewed positively by most users but uptake may be improved if providers emphasise the privacy and convenience it offers, as well as the accuracy of self-sampling. Providers should also consider measures to address user concerns around blood sampling and access to specialist advice.
