The authors describe participation in repeat testing and prevalence and determinants of repeat infection during three consecutive annual screening rounds.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Data collection included information on testkits sent, samples received and results of laboratory tests at time of baseline test and retest; (sexual) behavioural variables and socio-demographic variables were assessed. Chlamydia positives were requested to answer additional questions about treatment and partner notification 10\u2005days after checking their results.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Retest rate was 66.3% (2777\/4191). Retest chlamydia positivity was 8.8% (242\/2756) compared with a chlamydia positivity at first screening test of 4.1%. Chlamydia positivity was significantly higher in younger age groups (14.6% in 16\u201319\u2005years, 8.5% and 5.5% in 20\u201324 and 25\u201329\u2005years; p&lt;0.01); in participants with lower education (15.2% low, 11.1% medium and 5.1% high; p&lt;0.001) and in Surinamese\/Antillean (13.1%), Turkish\/Moroccan (12.9%) and Sub-Saharan African participants (18.6%; p&lt;0.01). At baseline, 88.7% infected participants had reportedly been treated and treatment of current partner was 80.1%.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>Automated retesting by sending a testkit after 6\u2005months to all chlamydia positives achieved high retest uptake and yielded a positivity rate twice as at baseline and can therefore be recommended as an additional strategy for chlamydia control. The high rate of repeat infections among known risk groups suggests room for improvement in patient case management and in effective risk reduction counselling.<\/jats:p><\/jats:sec>","DOI":"10.1136\/sextrans-2011-050455","type":"journal-article","created":{"date-parts":[[2012,6,24]],"date-time":"2012-06-24T00:55:35Z","timestamp":1340499335000},"page":"63-69","source":"Crossref","is-referenced-by-count":23,"title":["High yield of reinfections by home-based automatic rescreening of Chlamydia positives in a large-scale register-based screening programme and determinants of repeat infections"],"prefix":"10.1136","volume":"89","author":[{"given":"Hannelore M","family":"G\u00f6tz","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ingrid V F","family":"van den Broek","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christian J P A","family":"Hoebe","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elfi E H G","family":"Brouwers","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lydia L","family":"Pars","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Johan S A","family":"Fennema","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rik H","family":"Koekenbier","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sander","family":"van Ravesteijn","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eline L M","family":"Op de Coul","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jan","family":"van Bergen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2012,6,23]]},"reference":[{"key":"2024051321023450000_89.1.63.1","doi-asserted-by":"publisher","DOI":"10.1086\/648734"},{"key":"2024051321023450000_89.1.63.2","doi-asserted-by":"publisher","DOI":"10.1136\/sti.2006.022053"},{"key":"2024051321023450000_89.1.63.3","doi-asserted-by":"publisher","DOI":"10.1097\/OLQ.0b013e318227a366"},{"key":"2024051321023450000_89.1.63.4","doi-asserted-by":"publisher","DOI":"10.1086\/652395"},{"key":"2024051321023450000_89.1.63.5","unstructured":"NCSP. 2011. http:\/\/www.chlamydiascreening.nhs.uk\/ps\/index.html"},{"key":"2024051321023450000_89.1.63.6","unstructured":"CDC Centers for Disease Control and Prevention.
