A multivariable analysis of sociodemographic and behavioural characteristics of patients was conducted. Sexual health clinic appointments occurring within 90 days of a negative STI test, in asymptomatic individuals who tested either online or in clinic were determined. Factors associated with online STI testing and subsequent clinic use were determined using generalized estimating equations and reported as odds ratios (OR) with corresponding 95% confidence intervals (CI).<\/jats:p><\/jats:sec>Results<\/jats:title>31 847 online STI test requests and 40 059 clinic attendances incorporating STI testing were included. 79% (25020\/31846) of online STI test users and 49% (19672\/40059) of clinic STI test takers were asymptomatic. Online STI testing was less utilised (p<0.05) by men who have sex with men (MSM), non-Caucasians and those living in neighborhoods of greater deprivation. Subsequent clinic appointments within 90 days of an asymptomatic negative STI test occurred in 6.2% (484\/7769) of the online testing group and 33% (4960\/15238) for the clinic tested group. Re-attendance following online testing was associated with being MSM (aOR 2.55[1.58 to 4.09]\u2014MSM vs Female) and a recent prior history of STI testing (aOR 5.65[4.30 to 7.43] \u2018clinic tested\u2019 vs \u2018No\u2019 recent testing history).<\/jats:p><\/jats:sec>Conclusions<\/jats:title>Subsequent clinic attendance amongst online STI test service users with negative test results was infrequent, suggesting that their needs were being met without placing an additional burden on clinic based services. However, unequal use of online services by different patient groups suggests that optimised messaging and the development of online services in partnership with users are required to improve uptake.<\/jats:p><\/jats:sec>","DOI":"10.1371\/journal.pone.0281359","type":"journal-article","created":{"date-parts":[[2023,2,8]],"date-time":"2023-02-08T18:28:57Z","timestamp":1675880937000},"page":"e0281359","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":4,"title":["STI testing and subsequent clinic attendance amongst test negative asymptomatic users of an internet STI testing service; one-year retrospective study"],"prefix":"10.1371","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2097-8949","authenticated-orcid":true,"given":"Oluseyi","family":"Ayinde","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Louise","family":"Jackson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jara","family":"Phattey","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jonathan D.
