1542 - Provider Uptake of Extragenital Screening for Gonorrhea and Chlamydia in Active Duty Air Force Members with Incident HIV Diagnosis

Background: The prevalence of Neisseria gonorrhea (GC) and Chlamydia trachomatis (CT) is much higher at extragenital anatomic sites among men who have sex with men (MSM) with HIV infection. National guidelines recommend that all MSM with HIV infection undergo screening for extragenital sexually transmitted infections (EG-STIs), however uptake is low in many primary care settings. We evaluated EG-STI screening by primary care providers (PCPs) for US Air Force (USAF) members with incident HIV infection.

Methods: All USAF members newly diagnosed with HIV infection who received initial HIV specialty care with Infectious Disease (ID) providers at Brooke Army Medical Center from 2016-2018 (n=98) were included. A retrospective chart review was conducted to evaluate STI screening performed by PCPs within 1 week of HIV diagnosis compared to screening at entry into ID care. Demographic, clinical, laboratory and behavioral risk data were collected. STI screening included GC/CT EG-STIs, urethral GC/CT, syphilis, and hepatitis B and C.

Results: Patients were predominantly male (97.9%) with a median age of 26 (IQR 23, 32) years at HIV diagnosis (Table 1). A previous history of STIs was reported in 53 (54.1%) patients and the majority of males self-identified as MSM (66.3%) or bisexual (22.5%). The median time from HIV diagnosis to ID evaluation was 26 days (IQR 9, 33). PCPs performed any STI screening in 61 (62.2%) patients (Table 2). EG-STI screening was conducted in 3 (3.1%) patients overall and in (3.4%) MSM/bisexuals. A total of 31 (31.6%) patients had missed STIs; the majority due to EG-STIs of the rectum (71%) and pharynx (21.9%). All EG-STIs would have been missed by urethral GC/CT screening alone.Table 1

Conclusion: EG-STI screening uptake was low among PCPs evaluating USAF members with incident HIV infection. Underutilization of EG-STI screening can result in missed infections and forward transmission of GC/CT. Barriers to low uptake need to be explored. Continued education and training of PCPs may be necessary to improve uptake of EG-STI screening.
