Extragenital self-collection testing for gonorrhea and chlamydia: A feasibility study for expanding STI screening in the Veterans Health Administration.

Rectal and pharyngeal infections with gonorrhea and chlamydia are of concern because they are associated with higher risk of HIV acquisition. Extragenital screening in asymptomatic persons at high risk may have the potential to reduce the incidence of these sexually transmitted infections (STIs). Several testing platforms are available for the testing of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) using nucleic acid amplification tests (NAATs). Self-collected extragenital samples are currently not approved by the US Food and Drug Administration in any NAAT platform. This study compares the analytical performance of self-collected extragenital specimens to that of clinician-collected specimens. We performed a multicenter/multiplatform validation study as a National Veterans Health Administration Pathology and Laboratory Medicine quality improvement project, with 9 different participating sites. Self-collected specimens were obtained at the same time as clinician-collected specimens. Clinician-collected specimens were used as the gold standard to evaluate the sensitivity and specificity of self-collection. A total of 2324 individual tests were analyzed (501 rectal and 661 oropharyngeal). The sensitivity was 94.44% for CT and 100% for NG for rectal specimens, whereas it was 100% for CT and 97.22% for NG for oral specimens. Specificity for oral specimens was 99.85% for CT and 99.36% for NG, whereas for rectal specimens, it was 99% for CT and NG. Self-collected specimens for extragenital CT/NG testing are highly sensitive and specific, with negative predictive values of 100%. Self-collection has the potential to overcome a major barrier for STI screening by providing an accessible, convenient, and patient-centered alternative.

Impact of education and clinic site champion on extragenital testing for sexually transmitted infections.

Sexually transmitted infections (STIs) are on the rise in the United States. Infections at extragenital (EG) sites (throat or rectum) may serve as an overlooked reservoir for STIs. The aims of this project were to determine the proportion of patients receiving EG testing and to observe the impact of an educational intervention. Phase I included four urgent care clinics and baseline data for adults receiving STI testing (Chlamydia trachomatis and Neisseria gonorrhoeae). Clinics received access to an educational presentation regarding the importance of EG testing. Two of these clinics served as pilot sites for the implementation of self-collection kits. Phase II involved further expansion and utilization of clinic site champions. Phase I baseline data indicated that less than 1% of samples from patients receiving STI testing were from EG sites. There was an increase in EG testing after the educational intervention and implementation of self-collection kits. A larger increase in EG testing was seen after utilization of a site champion in Phase II. EG infections serve as a potential source for STI transmission which makes multi-site testing necessary. Our interventions to improve EG testing were most effective in Phase II after implementing a clinic site champion.

2666. Rates of STI Testing and Diagnoses among Patients with Mpox in New York City, 2022

Abstract Background The 2022 global mpox outbreak occurred in the context of rising rates of sexually transmitted infections (STIs). We hypothesize that concurrent STI rates were underestimated due to inadequate testing during virtual visits and non-sexual health clinical settings. Methods We included data from all patients with confirmed mpox (through non-variola orthopoxviral PCR testing) from June 25 to October 17, 2022 at an urban tertiary academic center in New York. Manual chart review supplemented data extracted from the electronic medical record. We calculated descriptive statistics for HIV, syphilis, genitourinary, rectal, and pharyngeal gonorrhea/chlamydia (GC/CT) screening and diagnosis rates. We evaluated relationships between site-specific symptoms and extragenital testing. Results Of 228 individuals in the database, 98% were male at birth, the median age was 34 years. 40% were Hispanic and 27% Black. 50% were living with HIV. Only 41% were tested for other STIs in the two weeks prior to their mpox diagnosis. At the time of their mpox visit, 62.7% of patients were tested for syphilis, with 45.5% showing evidence of active or previously treated syphilis. 67 persons without known HIV were tested for HIV, resulting in 3 new diagnoses within 2 weeks of mpox diagnosis. 57.5% of patients were screened with a genitourinary GC/CT nucleic acid amplification testing (NAAT), with 2.3% and 3.8% positive for gonorrhea and chlamydia, respectively. 46.5% were screened with a rectal GC/CT NAAT, with 16.0% and 6.6% positive for gonorrhea and chlamydia, respectively. 47.4% of individuals were screened with a pharyngeal GC/CT NAAT, with 7.4% and 0.9% positive for gonorrhea and chlamydia, respectively. Site specific GC/CT NAATs were obtained from 52.2%, 55%, and 54% of patients with urinary, rectal and pharyngeal signs or symptoms, respectively. Without extragenital testing, 10 of 28 total gonorrhea cases (35.7%) and 3 of 13 total chlamydia cases (23.1%) would have been missed. Conclusion STI testing was insufficient in people with confirmed mpox, likely leading to under diagnosis of STIs. HIV testing was inadequate in at-risk individuals, and patients presenting with site-specific symptoms were too frequently not offered targeted testing.

2685. Impact of Education and Clinic Site Champion on Extragenital Testing for Sexually Transmitted Infection

Abstract Background Over the last several years sexually transmitted infections (STIs) have been on the rise in the United States. A potential area for improving the diagnosis of STIs is appropriate testing of extragenital (EG) sites (i.e., throat or rectum). These sites may serve as a reservoir for infection and lead to increased transmission if not identified and treated. Prior studies have shown that in men who have sex with men, genital testing alone misses >70% of STIs. In other patient groups, this may range from 10-40%. The aims of this project were twofold: to determine the proportion of patients receiving EG STI testing, and to observe the effect of a two-phase educational intervention on EG site testing. Methods Phase I (Jul-Dec 2021) included four urgent care clinics within a Midwest health system. Retrospective baseline data was ascertained for all adults receiving STI testing for Chlamydia trachomatis (CT) and Neisseria gonorrhea (GC) at these clinics. Next, all four clinics received access to an educational presentation regarding the importance of EG testing for STI detection. Two of these clinics served as pilot sites for the implementation of patient self-collection kits. Data was compiled for all adults undergoing STI testing at these clinics for a 6-month period. Phase II (Jul 2022-Mar 2023) involved further expansion and utilization of a site champion at several family medicine clinics including on-site promotion of multi-site testing and patient self-collection. Educational materials as in Phase I were provided to site champions Results Phase I baseline data indicated that less than 1% of samples from patients receiving STI testing were obtained from EG sites. There was a small increase in EG site testing after the educational intervention and implementation of self-collected swab kits (Table 1). Phase II data showed an increase in EG testing after the utilization of a clinic site champion and the sharing of testing data in family medicine clinics (Table 2). Conclusion Rates of STIs have reached an all-time high in the United States. EG infections serve as potential sources for STI transmission. Adequate multi-site testing is necessary. Implementation was most effective when a clinic site champion was identified, and clinic testing data was provided to them. Disclosures All Authors: No reported disclosures

Identifying the Need for and Availability of Evidence-Based Care for Sexually Transmitted Infections in Rural Primary Care Clinics.

Increasing rates of bacterial sexually transmitted infections (STIs) may lead to increased HIV rates, as the STI and HIV epidemics are syndemic. Centers for Disease Control and Prevention guidelines recommend including extragenital (i.e., rectal and/or pharyngeal) STI screenings for certain populations at increased risk of STIs and concurrent infections with HIV. A descriptive study was conducted by interviewing staff members from 4 rural primary care clinics in areas of high need for STI and HIV services in South Carolina. Qualitative data about their clinical practices in 2021 were obtained. The primary outcome was to determine the awareness and availability of health care services associated with STI and HIV care in these locations. Clinics in target counties provided limited STI and HIV testing and treatment services, especially for populations at risk of infection, indicating the need for additional clinical training and professional development for all clinic staff. Specifically, only 1 of 4 clinics provided extragenital STI testing, and no clinics reported prescribing preexposure prophylaxis. Rural primary care clinics can fill important gaps in the availability of STI and HIV services with appropriate support and incentives. Findings from this study may aid in facilitating policy (state Medicaid agency) and program (state health department) decisions related to STI and HIV testing and treatment.

Gonorrheal and chlamydia yield for genital and extragenital testing in children evaluated for sexual abuse

ObjectiveTexas Forensic Nurse Examiners (TXFNE) performs routine testing of genital and non-genital sites for Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG), and further testing for other sexually transmitted pathogens. The current Centers for Disease Control and Prevention (CDC) guidelines recommend that testing be based primarily on patient history of type of sexual contact, patient age, community prevalence of sexually transmitted infections (STIs), perpetrator risk factors for STIs, and patient symptoms (Centers for Disease Control and Prevention, 2021). In this study, we were interested in determining whether our practice of testing all sites in all prepubertal patients presenting for sexual abuse for CT and NG resulted in identification of infections that would have been missed if testing had been limited to disclosed sites of sexual contact. MethodsWe conducted a retrospective chart review of all children younger than 14 years who presented to a clinical or hospital site for evaluation by TXFNE in Harris County or surrounding counties during the period January 2020–December 2021. ResultsOf the 675 patients tested, 61 patients (9 %) had genital injuries and 45 patients (7 %) had either reported symptoms or examination findings consistent with possible STI infection. There were 11 patients who had positive gonorrhea and/or chlamydia results. Of the 11 patients with a positive result, 10 patients' reported history of type of contact did not fully match sites that tested positive. Diagnosis of STI infection would have been missed for 5 patients if testing had been limited to the disclosed sites of sexual contact. ConclusionPositive results for CT and NG at undisclosed body sites in children presenting with concern for sexual abuse most likely represent infection from sexual contact. Limiting STI testing based on disclosed contact may lead to missed NG and CT infections in prepubertal patients with concern for sexual abuse. This can lead to delayed treatment of the infection and a missed opportunity to ensure the safety of the child.

Understanding the effect of an educational intervention to optimize HIV testing strategies in primary care in Amsterdam – results of a mixed-methods study

BackgroundIn the Netherlands, general practitioners (GPs) play a key role in provider-initiated HIV testing, but opportunities for timely diagnosis are regularly missed. We implemented an educational intervention to improve HIV testing by GPs from 2015 to 2020, and observed a 7% increase in testing in an evaluation using laboratory data. The objective for the current study was to gain a deeper understanding of whether and how practices and perceptions of GPs’ HIV/sexually transmitted infection (STI) testing behaviour changed following the intervention.MethodsWe performed a mixed-methods study using questionnaires and semi-structured interviews to assess self-reported changes in HIV/STI testing by participating GPs. Questionnaires were completed by participants at the end of the final educational sessions from 2017 through 2020, and participating GPs were interviewed from January through March 2020. Questionnaire data were analysed descriptively, and open question responses were categorised thematically. Interview data were analysed following thematic analysis methods.ResultsIn total, 101/103 participants completed questionnaires. Of 65 participants that were included in analyses on the self-reported effect of the programme, forty-seven (72%) reported it had changed their HIV/STI testing, including improved STI consultations, adherence to the STI consultation guideline, more proactive HIV testing, and more extragenital STI testing. Patients’ risk factors, patients’ requests and costs were most important in selecting STI tests ordered. Eight participants were interviewed and 15 themes on improved testing were identified, including improved HIV risk-assessment, more proactive testing for HIV/STI, more focus on HIV indicator conditions and extragenital STI testing, and tools to address HIV during consultations. However, several persistent barriers for optimal HIV/STI testing by GPs were identified, including HIV-related stigma and low perceived risk.ConclusionsMost GPs reported improved HIV/STI knowledge, attitude and testing, but there was a discrepancy between reported changes in HIV testing and observed increases using laboratory data. Our findings highlight challenges in implementation of effective interventions, and in their evaluation. Lessons learned from this intervention may inform follow-up initiatives to keep GPs actively engaged in HIV testing and care, on our way to zero new HIV infections.

Extragenital Sexually Transmitted Infections Testing During COVID-19 Pandemic Among Youth Involved in the Juvenile Justice System.

Studies have shown lower screening for sexually transmitted infections (STIs) during the COVID-19 pandemic. It is unclear how the pandemic affected STI testing among juvenile justice-involved youth, especially for extragenital gonorrhea and chlamydia. Retrospective chart review was conducted between March 2020 and June 2021 utilizing electronic health records of youth seen at a preadjudication facility in the southwest United States. Rates of extragenital testing were compared with prepandemic rates. Overall, 574 youth were observed; 86% were male, mean age was 15.4 years, and 48.6% were Black. Of the youth reporting performing oral sex, 57% were tested for oropharyngeal STIs compared to 33.5% in 2018 to 2019. Twenty percent of those reporting anal receptive sex were tested for rectal infections compared to 25.9% before the pandemic. Pandemic testing for oropharyngeal STIs increased but rectal testing decreased. Overall, testing rates remained low.

Sexual healthcare and at-home STI test collection: attitudes and preferences of transgender women in the Southeastern United States.

HIV and sexually transmitted infections (STIs) disproportionally affect transgender women in the United States, particularly in the Southeast where rates of HIV and bacterial STIs are especially high. Despite the high HIV/STI burden among transgender women, their engagement in sexual healthcare services, including HIV/STI testing, is low. Understanding reasons for this disconnect is essential in developing HIV/STI prevention efforts for this population, especially in the Southeastern US, where access to affirming sexual healthcare providers and resources is limited. We aimed to perform an exploratory qualitative study to describe the attitudes and preferences of transgender women living in Alabama with regards to sexual healthcare and at-home STI test collection. Transgender women ≥18 years old residing in Alabama were invited to participate in virtual individual in-depth interviews via Zoom. The interview guide explored participant experiences engaging with sexual healthcare services as well as preferences related to extragenital (i.e., rectal, pharyngeal) and at-home STI testing for gonorrhea and chlamydia. A trained qualitative researcher coded transcripts after each interview and iteratively amended the interview guide as themes emerged. Data were coded and thematically analyzed using NVivo qualitative software. Between June 2021-April 2022, 22 transgender women were screened and 14 eligible women enrolled. Eight participants were white (57%), and six were black (43%). Five participants (36%) were living with HIV and engaged with HIV care services. Interview themes included preference for sexual healthcare environments specializing in LGBTQ+ care, enthusiasm toward at-home STI testing, an emphasis on affirming patient-provider interactions in sexual healthcare settings, a preference for sexual healthcare providers involved in STI testing who were not cisgender men, and gender dysphoria around sexual health discussions and testing. Transgender women in the Southeastern US prioritize affirming provider-patient interactions, however resources in the region are limited. Participants were enthusiastic about at-home STI testing options, which have the potential to mitigate gender dysphoria. Further investigation into development of remote sexual healthcare services for transgender women should be performed.

Comparison of the burden of self-reported bacterial sexually transmitted infections among men having sex with men across 68 countries on four continents

BackgroundMen who have sex with men (MSM) are in general more vulnerable to sexually transmitted infections (STIs) than the heterosexual men population. However, surveillance data on STI diagnoses lack comparability across countries due to differential identification of MSM, diagnostic standards and methods, and screening guidelines for asymptomatic infections.MethodsWe compared self-reported overall diagnostic rates for syphilis, gonorrhea, and chlamydia infections, and diagnostic rates for infections that were classified to be symptomatic in the previous 12 months from two online surveys. They had a shared methodology, were conducted in 68 countries across four continents between October 2017 and May 2018 and had 202,013 participants.ResultsUsing multivariable multilevel regression analysis, we identified age, settlement size, number of sexual partners, condom use for anal intercourse, testing frequency, sampling rectal mucosa for extragenital testing, HIV diagnosis, and pre-exposure prophylaxis use as individual-level explanatory variables. The national proportions of respondents screened and diagnosed who notified some or all of their sexual partners were used as country-level explanatory variables. Combined, these factors helped to explain differences in self-reported diagnosis rates between countries. The following differences were not explained by the above factors: self-reported syphilis diagnoses were higher in Latin America compared with Europe, Canada, Israel, Lebanon, and the Philippines (aORs 2.30 – 3.71 for symptomatic syphilis compared to Central-West Europe); self-reported gonorrhea diagnoses were lower in Eastern Europe and in Latin America compared with all other regions (aORs 0.17-0.55 and 0.34 - 0.62 for symptomatic gonorrhea compared to Central-West Europe); and self-reported chlamydia diagnoses were lower in Central East and Southeast Europe, South and Central America, and the Philippines (aORs 0.25 - 0.39 for symptomatic chlamydia for Latin American subregions compared to Central West Europe).ConclusionsPossible reasons for differences in self-reported STI diagnosis prevalence likely include different background prevalence for syphilis and syndromic management without proper diagnosis, and different diagnostic approaches for gonorrhea and chlamydia.

Improving provider-initiated testing for HIV and other STI in the primary care setting in Amsterdam, the Netherlands: Results from a multifaceted, educational intervention programme.

In the Netherlands, general practitioners (GPs) play a key role in HIV testing. However, the proportion of people diagnosed with late-stage HIV remains high, and opportunities for earlier diagnosis are being missed. We implemented an educational intervention to improve HIV and STI testing in primary care in Amsterdam, the Netherlands. GPs were invited to participate in an educational program between 2015 and 2020, which included repeat sessions using audit and feedback and quality improvement plans. Data on HIV, chlamydia and gonorrhoea testing by GPs were collected from 2011 through 2020. The primary outcome was HIV testing frequency, which was compared between GPs before and after participation using Poisson regression. Secondary outcomes were chlamydia and gonorrhoea testing frequencies, and positive test proportions. Additional analyses stratified by patient sex and age were done. GPs after participation performed 7% more HIV tests compared to GPs before participation (adjusted relative ratio [aRR] 1.07, 95%CI 1.04-1.09); there was no change in the proportion HIV positive tests (aRR 0.87, 95%CI 0.63-1.19). HIV testing increased most among patients who were female and ≤19 or 50-64 years old. After participation, HIV testing continued to increase (aRR 1.02 per quarter, 95%CI 1.01-1.02). Chlamydia testing by GPs after participation increased by 6% (aRR 1.06, 95%CI 1.05-1.08), while gonorrhoea testing decreased by 2% (aRR 0.98, 95%CI 0.97-0.99). We observed increases specifically in extragenital chlamydia and gonorrhoea testing. The intervention was associated with a modest increase in HIV testing among GPs after participation, while the proportion positive HIV tests remained stable. Our results suggest that the intervention yielded a sustained effect.

Availability of Extragenital Chlamydia and Gonorrhea Testing in 6 High-Incidence States.

Extragenital testing (rectal and oropharyngeal) of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) increases the detection of CT/NG infections, compared with genital testing alone. The Centers for Disease Control and Prevention recommends annual extragenital CT/NG screening for men who have sex with men, and additional screenings for women and transgender or gender-diverse individuals if certain sexual behaviors and exposures are reported. Prospective computer-assisted telephonic interviews were conducted with 873 clinics between June 2022 and September 2022. The computer-assisted telephonic interview followed a semistructured questionnaire that included closed-ended questions on the availability and accessibility of CT/NG testing. Of the 873 clinics, CT/NG testing was offered in 751 clinics (86.0%), and extragenital testing was offered in only 432 clinics (57.5%). Most clinics (74.5%) with extragenital testing do not offer tests unless patients request them and/or report symptoms. Additional barriers to accessing information on available CT/NG testing include clinics not picking up the telephone, disconnecting the call, and unwillingness or inability to answer questions. Despite evidence-based recommendations from the Centers for Disease Control and Prevention, the availability of extragenital CT/NG testing is moderate. Patients seeking extragenital testing may encounter barriers such as fulfilling specific criteria or being unable to access information on testing availability.

Landscape Review of Mail-in Self-Collection, Programs for Sexually Transmitted Infections.

Mail-in self-collection of samples with centralized reference laboratory sexually transmitted infection (STI) testing has been shown to be feasible with equivalent performance. Commercial, fee-for-service mail-in testing Web sites seem to be popular. These sites are currently unregulated by the US Food and Drug Administration. To compile a list of US organizations offering mail-in testing for STIs/HIV, the phrases "mail-in STI testing" and "home STI testing" were entered into search engines. Supplementary information was collected by organization email or "Contact Us" submission. Information was collected from 20 programs in the United States offering STI mail-in, self-collection testing services. Five programs (25%) were free to consumers. Six organizations (30%) only offered prefixed kits (STIs tested could not be selected). Half of the organizations provided extragenital testing, 2 (10%) did not provide extragenital testing, and the 8 others (40%) did not clarify. Three organizations (15%) used their own laboratory, 11 (55%) did not provide laboratory information. One commercial laboratory provided services to 5 organizations. Mail-in self-collection services are ubiquitous and exist in all states except 2; STI testing public health programs that offer testing at no cost to the consumer are only in 46% of states. Mail-in testing is likely a permanent fixture in sexual health services and will be an important component of a hybrid approach that complements that of static clinic services.

2211. High prevalence of Chlamydia trachomatis and Neisseria gonorrhoeae identified through routine screening for rectal, pharyngeal, and urethral infections within a HIV pre-exposure prophylaxis program in Hanoi, Vietnam

Abstract Background Pre-exposure prophylaxis (PrEP) is highly effective for HIV prevention and is being scaled up globally. Patients on PrEP have high rates of bacterial STIs, like Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG), thus routine screening is recommended. However, access to screening tests for STIs are limited in many low-resource settings. The objectives of this study were to determine the prevalence of CT and NG among participants in Vietnam’s first PrEP program. Methods From January through April 2022 participants in the PrEP program at the Sexual Health Promotion Clinic in Hanoi, Vietnam were recruited to study STI prevalence. Study participants completed a survey collecting demographic, behavioral and clinical characteristics. Participants self-collected urine, rectal, and pharyngeal specimens for nucleic-acid testing. Participants positive for NG had an additional specimen collected for culture and antibiotic susceptibility. Results In total, 108 participants were enrolled, median age was 24 years (IQR: 22– 28). All were male and reported having sex with men in the prior 12 months. The median number of sex partners in the prior 1 month was 1 (IQR: 1 – 2). Symptoms within the prior week were reported by 41.7% (45/108) – 19.4% reported rectal, 15.7% reported urethral, and 26.9% reported pharyngeal symptoms. The overall prevalence of CT or NG infections was 31.5% (34/108). The prevalence of CT was 24.1% (26/108); by anatomic site, there were 17 (15.7%) rectal, 10 (9.3%) pharyngeal, and 6 (5.6%) urethral infections. The prevalence of NG was 13.0% (14/108); there were 12 (11.1%) pharyngeal, 9 (8.3%) rectal, and 0 urethral infections. Among participants reporting any symptoms, CT prevalence was 26.7% (12/45) and NG prevalence 13.3% (6/45). All infections were treated. Conclusion The prevalence of CT and NG was very high among this population of young MSM in a PrEP program in Hanoi, Vietnam. A high proportion of CT infections were rectal (65%) and 86% of NG infections were pharyngeal. These findings highlight the need for expanded access to extragenital nucleic-acid testing among PrEP programs in low- and middle-income countries. Studies demonstrating the benefit of CT/NG screening and treatment within PrEP programs are urgently needed.

Added Value of Extragenital Sexually Transmitted Infection Testing in "IWantTheKit" Program Users.

The 2021 Centers for Disease Control and Prevention sexually transmitted infection treatment guidelines recommend extragenital testing for gonorrhea and chlamydia in men who have sex with men and for women based on reported behaviors and exposures. The "IWantTheKit (IWTK)" program is a free online platform for specimen self-collection and mail-in for combined chlamydia/gonorrhea testing. We sought to assess the additional diagnostic value of extragenital testing compared with genital testing only for chlamydia/gonorrhea and determine factors associated with a positive extragenital test result among IWTK users. From August 2013 to January 2022, 7612 unique IWTK users returned swabs for testing; 3407 (45%) users requested both genital and extragenital tests and were included in this analysis. Descriptive statistics were summarized for demographic characteristics, reported behaviors, and genital and extragenital test results, and data were stratified by gender and age group. A logistic regression model was used to estimate associations between factors and extragenital sexually transmitted infection positivity. Chlamydia positivity rates were 4.7%, 2.4%, and 1.5% at genital, extragenital, and both sites, respectively; for gonorrhea, 0.4%, 1.1%, and 0.4% were positive at those sites, respectively. Among women, age 25 years and younger was significantly associated with extragenital chlamydia (odds ratio [OR], 4.0; P = 0.010). Being in high-risk quiz score group was associated with extragenital chlamydia (OR, 2.6; P = 0.005) and extragenital gonorrhea in men and women (OR, 8.5; P = 0.005). Extragenital testing detected additional chlamydia and gonorrhea cases in the IWTK user population that would have been missed by genital-only testing, especially for women younger than 25 years and people reported to be at high risk.

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.

Comprehensive Sexually Transmitted Infection Screening and Testing Interventions in a Predominantly Heterosexual Population with HIV at a Health Center.

In the United States, sexually transmitted infections (STIs) have remained elevated for the fifth consecutive year from 2015 to 2019. There is a need to implement standardization of the US Centers for Disease Control and Prevention STI screening and testing recommendations. Higher STI incidence populations such as people with HIV, men who have sex with men, and adolescents and young adults, are frequently not screened and tested for bacterial STIs as recommended. Federally qualified health centers (FQHCs) have the potential to deliver STI services for at-risk individuals as a routine component of primary care. Comprehensive sexual histories using audio computer-assisted self-interview software on electronic devices were done at each clinic visit at a FQHC. Extragenital site testing for chlamydia and gonorrhea, and blood drawn for syphilis testing was completed onsite based on the sexual history responses. Out of 432 eligible clients, 230 clients consented to having their data used for evaluation in this study. Sexual orientation was reported as heterosexual or straight by 86.5% (n = 199), 10.9% (n = 25) as gay/lesbian/same-sex loving, and 2.6% (n = 6) as bisexual or pansexual. Specimen collection took place over a 16-month period and included 80% (n = 855) urine, 13% (n = 140) pharyngeal, and 6.4% (n = 68) rectal samples. Positivity rates included 10% (n = 7) rectal, 6% (n = 8) pharyngeal, and 2% (n = 20) urine samples. Findings identified higher positivity rates among pharyngeal and rectal specimens compared to urogenital specimens. The feasibility of implementing a comprehensive STI screening and testing process in a FQHC is attainable and beneficial.

Anal and Oral Sex Behaviors Among Young Black Men Who Have Vaginal Sex: Evidence of the Need for Extragenital Testing for Chlamydia and Gonorrhea.

Unprotected oral and anal sex may result in extragenital sexually transmitted infections. The purposes of this study were to describe sexual behaviors, barrier use, and chlamydia/gonorrhea (Ct/GC) positivity among young Black men who have sex with women, and to examine the potential influence of extragenital infections on genital infections. Young Black men who had vaginal sex were screened for Ct/GC in New Orleans, LA, from August 14, 2019, to February 29, 2020. Audio/computer-assisted self-interviews were used to collect data on demographics and sexual behaviors. χ2 /Fisher exact or t test/Wilcoxon rank tests were used to assess differences in behaviors by Ct/GC positivity. Among 373 men studied, 619 female partnerships were reported in the past 2 months. Vaginal sex was reported in all partnerships per study protocol, receiving fellatio in 42.7%, performing cunnilingus in 35.7%, and penile-anal sex in 5.9%. Although 31.4% of the men consistently used condoms for vaginal sex with all partners, consistent barrier use was low during cunnilingus (0.5%) and fellatio (5.1%). Urethral infection rates among all men in the sample were 12.6% for Ct and 1.6% for GC. There was no significant difference in Ct/GC rates between those using and not using condoms consistently during vaginal sex ( P = 0.38). Unprotected oral sex with female partners was common. The high rate of genital infection among men who used condoms consistently for vaginal sex suggests that oral infections could be serving as a reservoir of genital infection. Testing at all sites of exposure for youth who engage in heterosexual sex is merited.

A Missed Opportunity: Extragenital Screening for Gonorrhea and Chlamydia Sexually Transmitted Infections in People With HIV in a Southeastern Ryan White HIV/AIDS Program Clinic Setting.

BackgroundGuidelines recommend annual screening for gonorrhea/chlamydia in sexually active people with HIV at multiple sites (urogenital, oropharyngeal, rectal). In the first year of multisite screening at our Ryan White HIV/AIDS Program clinic, we studied (1) sexual history documentation rate, (2) sexually transmitted infection (STI) screening rate, (3) characteristics associated with STIs, and (4) the percentage of extragenital STIs that would have been missed without multisite screening.MethodsParticipants were ≥14 years old with ≥1 in-person medical visit at our clinic in 2019. Descriptive analyses were performed, and adjusting for number of sites tested, a log-binomial model was used to estimate the association between characteristics and STI diagnosis in men.ResultsIn this cohort (n = 857), 21% had no sexual history recorded. Almost all STI diagnoses were among males (99.3%). Sixty-eight percent (253/375) received appropriate urogenital testing, 63% (85/134) received appropriate oropharyngeal testing, and 69% (72/105) received appropriate rectal testing. In male participants with ≥1 STI test (n = 347), Hispanic ethnicity and having a detectable HIV viral load were associated with an STI diagnosis. Of those diagnosed with an STI who had multisite testing, 96% (n = 25/26) were positive only at an extragenital site.ConclusionsScreening rates were similar across all anatomical sites, indicating no obvious bias against extragenital testing. In males, STIs were more frequently diagnosed in people who identify as Hispanic and those with detectable viral loads, which may indicate more condomless sex in these populations. Based on infections detected exclusively at extragenital sites, our clinic likely underdiagnosed STIs before implementation of multisite screening.
