Abstract
Background: Previous guidelines at the Sydney Sexual Health Centre (SSHC) recommended empirical antibiotic treatment for asymptomatic contacts of Neisseria gonorrhoeae at the time of testing. With increasing concerns around gonorrhoea antibiotic resistance, it has been suggested that asymptomatic contacts should only be treated based on test results. Methods: This retrospective study of data from the SSHC electronic medical record included a total of 295 gonorrhoea contacts from 1 January 2018 to 30 June 2018. The primary outcome was the proportion of asymptomatic gonorrhoea contacts with a positive gonorrhoea result from any anatomical site. Statistically significant differences in gonorrhoea positivity according to gender, sexual preference, use of PrEP, sex worker status, country of birth, preferred language and number of partners, were calculated using Fisher’s exact test. Results: The overall proportion of asymptomatic gonorrhoea contacts with a positive gonorrhoea result was 27.1% (95% CI: 22.1–32.6%). The proportion of gonorrhoea positivity was significantly higher in females compared to males (52.0% vs 25.7%, P < 0.01), gay and bisexual men compared to heterosexual men (28.7% vs 0%, P < 0.01) and non-users of PrEP compared to PrEP users (31.2% vs 12.5%, P < 0.05). No statistically significant differences in gonorrhoea positivity were found in subgroups divided by sex worker status, country of birth, preferred language and number of partners. Conclusion: The relatively low gonorrhoea positivity rate (27.1%) in asymptomatic gonorrhoea contacts at the SSHC between January and June 2018 supports guideline changes to no longer provide empirical antibiotic treatment to asymptomatic contacts.
