However, the disadvantages of EPT for chlamydia include missing the opportunity to test for other STIs and unnecessary use of antibiotics among non-infected partners. As part of a larger study that investigated the feasibility of EPT in the Netherlands, we explored the frequency of STI among a potential EPT target population of chlamydia-notified heterosexual men and women attending STI clinics for testing.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Cross-sectional national STI\/HIV surveillance data, which contain information on all consultations at STI clinics, were used to calculate STI positivity rates stratified by chlamydia notification and gender, and proportions of STI that were attributable to clients notified for chlamydia.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of all consultations in 2015 (n=101\u2009710), 14\u2009445 (14.4%) clients reported to be notified exclusively for chlamydia. Among chlamydia-notified clients, the chlamydia positivity rate was 34.2% (n=4947), and consequently 65.8% (n=9488) of them tested negative for chlamydia. Chlamydia-notified clients contributed to 10.2% of all gonorrhoea infections (n=174\/1702) and 10.9% of all infectious syphilis, HIV and\/or infectious hepatitis B infections (n=15\/173).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Implementing EPT without additional STI testing for all partners of chlamydia-infected index patients implies that STIs other than chlamydia will be missed. Although the chlamydia positivity rate was high among chlamydia-notified partners, two-thirds would unnecessarily use azithromycin. An evaluation of EPT against the current partner treatment strategy is needed to carefully weigh the potential health gains against the potential health losses and to explore the characteristics of EPT-eligible partners.<\/jats:p><\/jats:sec>","DOI":"10.1136\/sextrans-2017-053364","type":"journal-article","created":{"date-parts":[[2018,1,11]],"date-time":"2018-01-11T17:16:32Z","timestamp":1515690992000},"page":"619-621","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":8,"title":["STIs in sex partners notified for chlamydia exposure: implications for expedited partner therapy"],"prefix":"10.1136","volume":"94","author":[{"given":"Fleur","family":"van Aar","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Birgit H B","family":"van Benthem","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ingrid V F","family":"van den Broek","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1236-6224","authenticated-orcid":false,"given":"Hannelore M","family":"G\u00f6tz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2018,1,11]]},"reference":[{"key":"2020050723340602000_94.8.619.1","doi-asserted-by":"publisher","DOI":"10.1177\/0956462414547398"},{"key":"2020050723340602000_94.8.619.2","doi-asserted-by":"publisher","DOI":"10.1136\/sti.2005.018119"},{"key":"2020050723340602000_94.8.619.3","unstructured":"Draaiboek Partnermanagement bij soa\/hiv.
