Methods: All CT testing occasions among GBM from January 2011 to December 2014 were reviewed. Yield was defined as the proportion of testing occasions where CT was detected. Results: In all, 2917 GBM were tested on 5445 occasions. CT was detected on 439 (8.1%; 95% confidence interval (CI) 7.4\u20138.8%) occasions. Pharyngeal, urethral and anorectal CT were detected on 74 (1.4%; 95% CI 1.1\u20131.7%), 109 (2.0%; 95% CI 1.7\u20132.4%) and 333 (6.1%; 95% CI 5.5\u20136.8%) occasions respectively. Over the study period, there was a significant increase in pharyngeal CT yield (from 0.70% to 1.6%; odds ratio (OR) 1.25; 95% CI 1.01\u20131.55; Ptrend = 0.043), which remained borderline significant (OR 1.22; 95% CI 0.99\u20131.52; P = 0.067) when adjusted for age. There was no change in yield of either urethral or anorectal infections. Almost half the pharyngeal CT (n = 35; 47.3%) occurred without concurrent anogenital infection. Excluding those who would have received anti-chlamydial treatment for another reason, 27.0% of pharyngeal and 4.6% of all CT infections would not have been treated without pharyngeal testing. Conclusions: A recent temporal increase was observed in the yield of pharyngeal CT without a concurrent increase in anogenital yield. Ongoing surveillance is warranted to inform testing guidelines for GBM.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1071\/sh16181","type":"journal-article","created":{"date-parts":[[2017,3,15]],"date-time":"2017-03-15T18:00:01Z","timestamp":1489600801000},"page":"282-285","source":"Crossref","is-referenced-by-count":4,"title":["Increasing yield of pharyngeal Chlamydia trachomatis among male gay and bisexual clinic attendees in Sydney: an observational study"],"prefix":"10.1071","volume":"14","author":[{"given":"Sian Louise","family":"Goddard","sequence":"first","affiliation":[{"name":"ARPA Sexual Health, Sydney Local Health District, 16 Marsden Street, Camperdown, Sydney, NSW 2050, Australia."},{"name":"BThe Kirby Institute, UNSW Australia, Wallace Wurth Building, Sydney, NSW 2052, Australia."},{"name":"DCorresponding author.
