Key informant perspectives on a centralised contact tracing system for sexually transmitted infections.

Abstract

To meet the demand of contact tracing requirements associated with Aotearoa New Zealand's COVID-19 pandemic response, a national contact tracing service was established. Contact tracing for sexually transmitted infections (STIs) like chlamydia, gonorrhoea and syphilis is usually done at the clinic level, and evidence suggests it is under-resourced and often incomplete. We considered the utility of a centralised contact tracing service for STIs by interviewing key informants. Interviews took place between December 2021 and March 2022, and were audio-recorded, transcribed and analysed using thematic analysis. Twelve key informants from disciplines including sexual health, primary care, public health, research and contact tracing participated. Perceived benefits of a centralised system included efficiency, standardisation and reduced demands on clinician time. Potential challenges and considerations included concerns about trust and privacy, the importance of cultural safety, meeting the needs of priority populations and lack of local-level knowledge. A centralised contact tracing service could enable a more consistent and comprehensive approach to contact tracing for STIs and alleviate some of the burden on already stretched clinicians. However, successful contact tracing requires high levels of trust and for some populations this may be best achieved through trusted local providers, who could be supported, if needed, by centralised expertise.
