Automated Sexual History and Self-Collection of Extragenital Chlamydia and Gonorrhea Improve Detection of Bacterial Sexually Transmitted Infections in People with HIV.

With consistently rising rates of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) since 2014, the need for increased screening, testing, and treatment of bacterial sexually transmitted infections (STIs) in people at risk is clear. In this study, people with HIV were asked to complete a comprehensive audio computer-assisted self-interview sexual history at routine clinic-based laboratory visits every 3-6 months. The sexual health screening resulted in an automated summary of recommended bacterial STI tests. Self-collection of recommended extragenital CT/GC specimens was implemented to decrease the need for a provider to collect the specimen(s) and to give more control to the client. In total, extragenital CT/GC testing returned a 7.3% (n = 11) test positivity for CT and/or GC, with the highest test positivity of 14% (n = 7) among rectal swabs and 4% (n = 4) for pharyngeal swabs. Urogenital testing for combined CT/GC returned a 4.8% (n = 11) test positivity. All participants with extragenital CT/GC who underwent simultaneous urine testing returned discordant laboratory results, with urine collected at the same clinic visit resulting as negative. In addition, 7 of 11 (63.6%) of the positive extragenital GC/CT cases were asymptomatic. Therefore, extragenital site-specific testing was essential in appropriately diagnosing and treating CT and GC among participants. When extragenital STI testing was recommended, participants needing extragenital CT/GC specimens primarily chose self-collection after a brief demonstration. Error rates between self- versus provider-collected samples did not differ, and participants provided positive feedback on the intervention and self-collection process in satisfaction surveys taken at the end of each visit.
