Introduction Helping clients to find the right service in the right place at the right time is important for individual and public health. Many websites try to address this; however, providers lack control of their web profile and the accuracy of sign posting varies. A free confidential web/SMS service (http://www.sxt.org.uk) was therefore developed to support both providers and clients. All texts are charged at the standard SMS rate. Data collected were then evaluated for service utility, ability to provide gap analysis, met and unmet need and the capture of client feedback.

Methods Web site traffic was analysed by Google analytics whilst SMS usage, provider sign up, met and unmet need and gap analyses were made possible from data downloads. Marketing was initiated by business card adverts to South London colleges and MSM venues as well by Google Ads to London users.

Results There are currently 23 providers of sexual and reproductive health in SXT across 10 London boroughs. These providers include hospital and community sexual health clinics, primary care physicians and pharmacies. In addition, out of hours post-exposure prophylaxis providers and the three sexual assault referral centres have been included in SXT. All early adopters were able to edit their profile and add services within 20 min. Over 3 months, 701 unique visitors viewed the website with a bounce rate of 41%. Gap analyses of key services have been produced to inform service development in the London boroughs of Lambeth and Southwark. The SMS service had 74 users and the met need was 32%. Only 31 (0.04%) of all web and SMS users opted-in to provide qualitative feedback.

Conclusion A scaleable web/SMS tool has been developed to match provider services with client needs that both supports local marketing initiatives and captures client feedback. Additional provider, client and commissioner feedback is required to optimise SXT.
