Toward Zero New HIV Infections in Amsterdam in 2026: Building Bridges Between Community Organizations, Undocumented Migrants, and Sexual Health Care Providers.

In the 4 largest cities in the Netherlands, an estimated 400 people live with undiagnosed HIV, including 170 in Amsterdam. Amsterdam targets having zero new HIV infections in 2026. Undocumented migrants are disproportionately affected by HIV and often contract HIV after migration. Moreover, they often experience difficulties accessing health care. The aim of this study was to analyze the outcomes of an HIV/sexually transmitted infection testing program for undocumented migrants through community based testing. Between May 2021 and January 2022, data for this cross-sectional study were collected during outreach testing activities of the Amsterdam Center for Sexual Health of the Public Health Service, and the NGO Doctors of the World. Activities were organized in collaboration with migrant partner organizations. Participants were tested free-of-charge for HIV, syphilis, gonorrhea, chlamydia, and, if indicated, hepatitis B and C. Before testing, a health care provider-administered questionnaire was filled out. A total of 126 people from 22 countries were tested for HIV during 28 outreach activities. Mean age was 37 (IQR 32-43). Forty-nine people (39%) were additionally tested, (through self-sampling) for chlamydia, gonorrhea and syphilis, 42 (33%) for Hepatitis B and 14 (11%) for Hepatitis C. We found zero new HIV infections and 5 positive chlamydia cases.Reaching 52 HIV first time testers and 19 first time testers since migration shows the importance of these activities. The number of participants tested were lower than initially expected due to lower attendance per testing day for various reasons. To increase the likelihood of reaching undocumented migrants for HIV/sexually transmitted infection testing and linkage to care, focus should be on on-site provider-initiated testing, e.g. during outreach health care activities, and on easy access to centers for sexual health. Collaboration between health care providers and community stakeholders is essential.

Incentivization of Sexually Transmitted Infection Testing at a Large Public University

Abstract Background According to the United States (U.S.) Centers for Disease Control and Prevention, more than 2.5 million cases of syphilis, gonorrhea, and chlamydia were reported in 2022, with notable increases in gonorrhea and chlamydia. The highest rates of chlamydia, gonorrhea, and syphilis were found in men and women of college age. This study compared free STI testing events to usual care with regard to patient socio-economic factors and testing positivity rates. Methods The Department of Student Health & Wellness at a large, public university offers routine testing at a low cost, flat rate, including chlamydia, gonorrhea, hepatitis C Ab, syphilis and HIV testing. Two weeks of free testing were held during calendar year 2023. Utilization and positivity rates between free testing and regular testing weeks were compared using Pearson’s chi squared and Fisher Exact tests. Results A total of 8705 tests were performed during routine testing weeks with associated cost averaging 174 tests per week as compared to 1177 tests for the free testing weeks averaging 589 tests per week. Testing uptake during free testing weeks was higher among females (65.6% (n = 772) vs. 55.1% (n = 4797); p < 0.001) and minorities such as, Black or African American [11.3% (n = 133) vs. 9.4% (n = 813); p = 0.02], Hispanic [11.4% (n = 134) vs. 9.2% (n = 798); p = 0.02] and Asian [13.1% (n = 154) vs. 8.8% (n = 763); p < 0.001] when compared to testing during regular weeks. Chlamydial infection positivity rate was lower during the free testing weeks [1.8% (n = 7)] vs. [3.9% (n = 123); p = 0.04]. Gonorrhea, hepatitis C, HIV, and Syphilis positivity rates did not differ between the two testing periods. Conclusions Free STI testing in the context of a large, public university Student Health Department shows increased utilization. The establishment of free testing weeks was associated with an increase in female students and minorities use of testing services at a large public university. Key messages • Incentivization can improve STI testing utilization among university students. • The establishment of STI free testing periods can increase the use of testing services among minority students and females.

Impact of the COVID-19 pandemic on sexually transmitted infection testing and diagnosis in Lebanon: A retrospective chart review

BackgroundSocial distancing restrictions during the COVID-19 pandemic caused disruptions to sexual health services (SHS) worldwide. During the first year of the pandemic, Lebanon implemented multiple lockdowns during which SHS endured repetitive closures. We explore the impact of the pandemic on SHS delivery and the diagnosis rate of sexually transmitted infections (STIs) among attendees of a large sexual health clinic in Beirut, Lebanon. MethodsThis was a retrospective analysis of the clinic's database, including data on voluntary counseling and testing (VCT) for HIV, syphilis, hepatitis B virus (HBV), and hepatitis C virus (HCV). We compared the number and types of services provided, and the number and rate of positive VCT diagnoses pre- (Mar 2019–Feb 2020) and post- (Mar 2020–Feb 2021) COVID-19 onset. ResultsMen who have sex with men (MSM) comprised 35 % and 40 % of attendees pre- and post- COVID-19 onset, respectively. Post-COVID-19 onset, a total of 1350 VCT services and 406 medical consultations were provided, an overall 45 % decrease compared with pre-COVID-19 onset. The prevalence pre-COVID-19 onset of HIV, syphilis, HBV, and HCV was 0.8 %, 0.3 %, 0.2 %, and 0.1 %, respectively, and post-COVID-19 onset 1.2 %, 0.7 %, 0.3 %, and 0.3 %, respectively. Post-COVID-19 onset, 1.7 % of patients tested positive for any STI compared with 1.1 % pre-COVID-19 onset (OR: 1.5, 95%CI: 0.8–2.7). Close to 90 % of all positive diagnoses were among MSM. The prevalence of HIV, syphilis, HBV, and HCV among MSM in the total sample was 2.1 %, 1.2 %, 0.4 %, and 0.3 %, respectively. ConclusionCOVID-19 related closures led to substantial reduction in SHS accessibility among clinic attendees. STI positivity rates increased post-COVID-19 onset, although this increase was not statistically significant. Findings suggest that sexual risk behavior was taking place during the pandemic despite the lockdowns and highlight the need to minimize disruptions in provision of SHS during similar crises, particularly to key populations.

Telehealth for Reproductive Health Services for Economically Disadvantaged Youth

PurposeThere is a lack of studies describing reproductive health service use and outcomes with telehealth in publicly funded clinics in community settings for economically disadvantaged adolescents and young adults (AYA). This study sought to compare use of reproductive health services before and during the COVID-19 pandemic and analyze the types and quality of reproductive health-care services for patients who did and did not complete a telehealth visit. MethodsMedical records were reviewed for AYA who sought reproductive health services at 9 urban family planning and school-based clinics. Visit-type differences and associated factors by year of service and among those who did and did not complete telehealth visits were analyzed. ResultsTwenty-seven thousand nine hundred sixty-one unique patients were served between 2019 and 2021. As compared to 2019, in 2020 and 2021, there were significantly fewer visits by minors (<18 years old) versus young adults (18–24 years old) (p < .001), and by those with male versus female natal sex (p < .001). At least one telehealth visit was completed by 17.98% of patients. Telehealth visit completion was more likely in young adults, female, Black, non-Hispanic, and higher-income patients. Telehealth users were more likely to complete annual sexually transmitted infection testing, had a higher number of visits per year, and had higher odds of requiring a return visit within 2 weeks of the index visit (odds ratio 1.5, 95% confidence intervals 1.41–1.76). DiscussionOur findings illustrate disparities in telehealth use in this population of economically disadvantaged AYA and provides pragmatic targets for future interventions.

Sexually transmitted infection testing and diagnosis in adolescents and young adults with sickle cell disease.

Sexually transmitted infections (STIs) are common and disproportionately affect Black adolescents and young adults (AYAs). Less is known about STIs among Black AYAs with chronic conditions, such as sickle cell disease (AYAs-SCD). This study compared STI testing and diagnosis between AYAs-SCD and their peers, overall and among STI-related encounters. This retrospective, cross-sectional study used diagnosis and billing codes in the Pediatric Health Information System (PHIS) to identify inpatient and emergency department encounters from January 1, 2022 to May 31, 2023 among all AYAs 15-24years and those with STI-related diagnoses (e.g., "cystitis"). STI testing and diagnosis rates were compared between AYAs-SCD, non-Black AYAs, and Black AYAs, controlling for age, sex, and encounter setting. We identified 3602 AYAs-SCD, 177,783 Black AYAs, and 534,495 non-Black AYAs. AYAs-SCD were less likely to be tested for STIs than non-Black AYAs (odds ratio [OR]=0.26; adj. p<.001) and Black AYAs (OR=0.53; adj. p<.001). When tested, AYAs-SCD were more likely to be diagnosed with an STI than non-Black AYAs (OR=2.39; adj. p=.006) and as likely as Black AYAs (OR=0.67; adj. p=.15). Among STI-related encounters, AYAs-SCD were less likely to be tested than non-Black AYAs (OR=0.18; adj. p<.001) and Black AYAs (OR=0.44; adj. p<.001). No significant differences in STI diagnoses were found in this subset between AYAs-SCD and non-Black AYAs (OR=0.32; adj. p=.28) or Black AYAs (OR=1.07; adj. p=.99). STI care gaps may disproportionately affect AYAs-SCD. STIs should be considered when evaluating symptomatic AYAs-SCD in acute settings. More research is needed to further contextualize STI care for AYAs-SCD.

Connecting Female Entertainment Workers in Cambodia to Health Care Services Using mHealth: Economic Evaluation of Mobile Link.

Mobile Link is a mobile phone-based intervention to increase access to, and use of, health care services among female entertainment workers in Cambodia who face higher risks for specific diseases and gender-based violence. A multisite randomized controlled trial showed that Mobile Link connected female entertainment workers with outreach workers for information and escorted referrals after 6 months but did not lead to statistically significant improvements in HIV and sexually transmitted infection testing, contraceptive use, and condom use. This study aims to conduct a 3-part economic evaluation of Mobile Link to understand its costs, value, and affordability. We conducted cost, cost-effectiveness, and budget impact analyses of Mobile Link using cost and outcomes data from the Mobile Link trial and other sources. For the cost analysis, we estimated the total, per-person, and incremental costs of Mobile Link compared with usual care. Using probabilistic decision-analytic models, we estimated the 1-year cost-effectiveness of Mobile Link from payer and combined payer and patient perspectives by converting selected primary and secondary outcomes from the trial to disability-adjusted life years (DALYs) averted. Finally, we estimated the financial costs of scaling up Mobile Link's messaging and outreach services to 70% of female entertainment workers in 5 years. The incremental costs of Mobile Link were US $199 from a payer perspective and US $195 per person from a combined payer and patient perspective. With an average of 0.018 (95% predicted interval -0.088 to 0.126) DALYs averted, Mobile Link's cost-effectiveness was US $10,955 per DALY from a payer perspective (US $10,755 per DALY averted from a payer and patient perspective). The costs of Mobile Link would have to decrease by 85%, or its effectiveness would have to be 5.56 times higher, for the intervention to meet the upper limit of recommended cost-effectiveness thresholds in Cambodia (US $1671 per DALY averted). The 5-year cost of scaling Mobile Link to 34,790 female entertainment workers was estimated at US $1.64 million or US $46 per person per year. This study provided a comprehensive economic evaluation of Mobile Link. We found that Mobile Link is not likely to be cost-effective unless its costs decrease or its effectiveness increases. Scaling up Mobile Link to more female entertainment workers is estimated to cost less than the costs of the trial. Given the importance of linking female entertainment workers to essential services, future research should focus on enhancing the effectiveness of Mobile Link or developing new mobile health interventions for this population.

Facilitators of and Barriers to the Use of a Digital Self-Management Service for Diagnostic Testing: Focus Group Study With Potential Users.

Health care lags in digital transformation, despite the potential of technology to improve the well-being of individuals. The COVID-19 pandemic has accelerated the uptake of technology in health care and increased individuals' willingness to perform self-management using technology. A web-based service, Directlab Online, provides consumers with direct digital access to diagnostic test packages, which can digitally support the self-management of health. This study aims to identify the facilitators, barriers, and needs of Directlab Online, a self-management service for web-based access to diagnostic testing. A qualitative method was used from a potential user's perspective. The needs and future needs for, facilitators of, and barriers to the use of Directlab Online were evaluated. Semistructured focus group meetings were conducted in 2022. Two focus groups were focused on sexually transmitted infection test packages and 2 were focused on prevention test packages. Data analysis was performed according to the principles of the Framework Method. The Consolidated Framework for Implementation Research was used to categorize the facilitators and barriers. In total, 19 participants, with a mean age of 34.32 (SD 14.70) years, participated in the focus groups. Important barriers were a lack of privacy information, too much and difficult information, and a commercial appearance. Important facilitators were the right amount of information, the right kind of tests, and the involvement of a health care professional. The need for a service such as Directlab Online was to ensure its availability for users' health and to maintain their health. According to the participants, facilitators and barriers were comprehension of the information, the goal of the website, and the overall appearance of the service. Although the service was developed in cocreation with health care professionals and users, the needs did not align. The users preferred understandable and adequate, but not excessive, information. In addition, they preferred other types of tests to be available on the service. For future research, it would be beneficial to focus on cocreation between the involved medical professionals and users to develop, improve, and implement a service such as Directlab Online.

National Outpatient Sexually Transmitted Infection Testing in Pregnant Patients in the United States.

Introduction: Sexually transmitted infections (STIs) continue to increase in the United States and pregnant patients who acquire STIs are at risk for serious complications. This study estimated the utilization of preventative STI testing among pregnant outpatients on a national scale. Methods: This was a retrospective, cross-sectional study of outpatient visits in the National Ambulatory Medical Care Survey from 2014 to 2016 and 2018 to 2019. All patients reported as pregnant were included to assess STI testing for chlamydia, gonorrhea, hepatitis, and HIV. STI testing was described per 1,000 total visits overall and by subpopulations. Data weights were applied to generate national estimates. Results: Over 177 million visits were included, of which 87.5 per 1,000 included an STI test. Chlamydia testing was the most common, followed by HIV, gonorrhea, and hepatitis (58.0 vs. 42.3 vs. 41.5 vs. 20.3 per 1,000). STI testing rates varied across subpopulations (72.1-236.6 per 1,000 visits). Patients of Hispanic ethnicity, Black race, age ≤25 years old, and those seen by an obstetrics and gynecology (OB/GYN) provider had the highest rates of STI testing. Independent predictors of STI testing included: Black race (adjusted odds ratio [aOR]: 2.24, 95% confidence interval [95% CI]: 2.23-2.24), first trimester (aOR: 5.15, 95% CI: 5.14-5.16), government and private insurance (aOR: 1.90, 95% CI: 1.89-1.91 and aOR: 1.70, 95% CI: 1.69-1.71), and an OB/GYN provider specialty (aOR: 2.93, 95% CI: 2.93-2.94). Conclusions: STI testing in United States outpatient physician offices varied by subpopulations and across individual test types. Certain patient attributes, such as race, provider specialty, and payment source, were predictive of testing.

An mHealth Intervention for Gay and Bisexual Men's Mental, Behavioral, and Sexual Health in a High-Stigma, Low-Resource Context (Project Comunică): Protocol for a Randomized Controlled Trial.

The World Health Organization reported that 80% of new HIV diagnoses in Europe in 2014 occurred in Central and Eastern Europe. Romania has a particularly high HIV incidence, AIDS prevalence, and number of related deaths. HIV incidence in Romania is largely attributed to sexual contact among gay and bisexual men. However, homophobic stigma in Romania serves as a risk factor for HIV infection for gay and bisexual men. The Comunică intervention aims to provide a much-needed HIV risk reduction strategy, and it entails the delivery of motivational interviewing and cognitive behavioral therapy skills across 8 live text-based counseling sessions on a mobile platform to gay and bisexual men at risk of HIV. The intervention is based on the information-motivation-behavior and minority stress models. There is preliminary evidence suggesting that Comunică holds promise for reducing gay and bisexual men's co-occurring sexual (eg, HIV transmission risk behavior), behavioral (eg, heavy alcohol use), and mental (eg, depression) health risks in Romania. This paper describes the protocol for a randomized controlled trial designed to test the efficacy of Comunică in a national trial. To test Comunică's efficacy, 305 gay and bisexual men were randomized to receive Comunică or a content-matched education attention control condition. The control condition consisted of 8 time-matched educational modules that present information regarding gay and bisexual men's identity development, information about HIV transmission and prevention, the importance of HIV and sexually transmitted infection testing and treatment, heavy alcohol use and its associations with HIV transmission risk behavior, sexual health communication, finding social support, and creating sexual health goals. Participants undergo rapid HIV and syphilis testing and 3-site chlamydia and gonorrhea testing at baseline and the 12-month follow-up. Outcomes are measured before the intervention (baseline) and at the 4-, 8-, and 12-month follow-ups. The study was funded in September 2018, and data collection began in May 2019. The last participant follow-up was in January 2024. Currently, the data analyst is cleaning data sets in preparation for data analyses, which are scheduled to begin in April 2024. Data analysis meetings are scheduled regularly to establish timelines and examine the results as analyses are gradually being conducted. Upon completion, a list of manuscripts will be reviewed and prioritized, and the team will begin preparing them for publication. This study is the first to test the efficacy of an intervention with the potential to simultaneously support the sexual, behavioral, and mental health of gay and bisexual men in Central and Eastern Europe using motivational interviewing support and sensitivity to the high-stigma context of the region. If efficacious, Comunică presents a scalable platform to provide support to gay and bisexual men living in Romania and similar high-stigma, low-resource countries.

Youth and Guardian Expectations of Privacy in Adolescent Health Care

PurposeAdolescent access to confidential care is codified by most states with age-specific laws; however, adolescent and guardian awareness of these laws are poorly understood. In this study, we assessed adolescent and guardian perceptions of conditional confidentiality in health care. MethodsWe surveyed youth aged 11–18 years, and guardians accompanying youth seeking care at an urban adolescent outpatient clinic that provides adolescent primary and subspecialty care. Participants completed brief True/False surveys which queried whether a parent would be notified for common, hypothetical scenarios. We analyzed adolescent responses by age group and compared responses of adolescents and guardians. ResultsTwo hundred seventy nine adolescents and 178 guardians completed the survey. Among participants, 86% of adolescents and 67% of guardians believed they understood which health topics were confidential. Adolescent and guardian answers aligned with mandatory reporting laws for scenarios concerning safety and suicidality. Younger adolescents consistently underestimated their legal right to privacy for all hypothetical scenarios. Many adolescents anticipated disclosure to parents for confidential services, including contraception, pregnancy, and sexually transmitted infection testing. Guardians expected disclosure about sexual health services at higher rates than they did about substance use. DiscussionWe identified age-associated knowledge gaps among participants pertaining to adolescent privacy in the clinical setting. These deficits were found in a setting where adolescent privacy is routinely discussed, and our findings may underestimate the knowledge gap in the general pediatric population where confidentiality may not be discussed as often. Providers caring for adolescents share the responsibility of educating both youth and families about the importance of adolescent confidentiality.

Assessing the Performance of ChatGPT in Correctly Evaluating Preventive Screening Clinical Vignettes Commonly Seen in Obstetrics and Gynecology Practice [ID 2683617

INTRODUCTION: Preventive screening is vital in obstetrics and gynecology practice, where the accurate assessment of clinical vignettes is pivotal for delivering optimal care. This research delves into ChatGPT’s performance, an advanced language model, in evaluating common obstetrics and gynecology preventive screening scenarios. METHODS: We compiled a diverse dataset of obstetrics and gynecology clinical vignettes, covering areas like cervical and breast cancer screening, sexually transmitted infection testing, and prenatal care. Using 20 vignettes initially generated by ChatGPT and enriched with specific details, we rigorously assessed ChatGPT’s responses for clinical accuracy and relevance. Our evaluation was guided by quantitative metrics, aligning ChatGPT’s performance with recognized guidelines such as United States Preventive Services Task Force, American Society for Colposcopy and Cervical Pathology, American College of Obstetricians and Gynecologists, and more. RESULTS: ChatGPT displayed promise in comprehending obstetrics and gynecology clinical information. Out of 20 vignettes, only 2 (10%) fell short of evaluating the clinical vignette adequately. Among the remaining 18 vignettes, an impressive 15 (83%) adhered to the latest clinical guidelines, whereas 3 (17%) evaluations proved inaccurate. Notably, in 19 out of 20 vignettes (95%), ChatGPT deferred to the provider’s clinical judgment. CONCLUSION: This study underscores ChatGPT’s potential to assist obstetrics and gynecology practitioners in preventive screening decision-making. While promising, ChatGPT should complement, not replace, human expertise. Limitations include a focus on quantitative metrics; future research should delve into qualitative aspects of ChatGPT’s performance. Integrating ChatGPT into obstetrics and gynecology practice could enhance preventive screening quality and efficiency, potentially improving women’s health care outcomes. This research contributes to the broader discourse on AI integration in health care, particularly in women’s preventive health care, paving the way for further AI-driven solutions.

The insights and experiences shared aim to inform future research and the design of interventions targeting populations at high risk, particularly when facing unanticipated challenges. By addressing these areas, the article contributes to the decision-making for the design and delivery of effective strategies to improve the health outcomes among marginalized populations. The findings underscore the importance of flexibility and active participant engagement, cultivating strong relationships with community partners, utilizing technology and social media, and fostering a diverse research team that represents the heterogeneity of youth experiencing homelessness across race/ethnicity, gender identity, sexual orientation, and lived experiences. These recommendations aim to enhance participant access, engagement, and retention, while promoting rigorous research and meaningful study outcomes for YEH.

What Adolescents Say in Text Messages to Motivate Peer Networks to Access Health Care and Sexually Transmitted Infection Testing: Qualitative Thematic Analysis.

While rates of HIV and sexually transmitted infections (STIs) are extremely high among adolescents and young adults in the United States, rates of HIV and STI testing remain low. Given the ubiquity of mobile phones and the saliency of peers for youths, text messaging strategies may successfully promote HIV or STI testing among youths. This study aimed to understand the types of messages youths believe were motivating and persuasive when asked to text friends to encourage them to seek HIV or STI testing services at a neighborhood clinic. We implemented an adolescent peer-based text messaging intervention to encourage clinic attendance and increase STI and HIV testing among youths (n=100) at an adolescent clinic in San Francisco, California. Participants were asked to send a text message to 5 friends they believed were sexually active to encourage their friends to visit the clinic and receive STI or HIV screening. Thematic analysis was used to analyze the content of the text messages sent and received during the clinic visit. Member checking and consensus coding were used to ensure interrater reliability and significance of themes. We identified four themes in the messages sent by participants: (1) calls to action to encourage peers to get tested, (2) personalized messages with sender-specific information, (3) clinic information such as location and hours, and (4) self-disclosure of personal clinic experience. We found that nearly all text messages included some combination of 2 or more of these broad themes. We also found that youths were inclined to send messages they created themselves, as opposed to sending the same message to each peer, which they tailored to each individual to whom they were sent. Many (40/100, 40%) received an immediate response to their message, and most participants reported receiving at least 1 positive response, while a few reported that they had received at least 1 negative response. There were some differences in responses depending on the type of message sent. Given the high rates of STI and HIV and low rates of testing among adolescents, peer-driven text messaging interventions to encourage accessing care may be successful at reaching this population. This study suggests that youths are willing to text message their friends, and there are clear types of messages they develop and use. Future research should use these methods with a large, more diverse sample of youths and young adults for long-term evaluation of care seeking and care retention outcomes to make progress in reducing HIV and STI among adolescents and young adults.

Approach to sexually transmitted infection testing for men who have sex with men.

To provide a guide on appropriate sexually transmitted infection (STI) testing for primary care providers to use with patients who identify as men who have sex with men (MSM). Canadian guidelines for STI testing and enteric and protozoan infections; Ontario guidelines for HIV screening and mpox; and US guidelines for STI testing. Across Canada rates of sexually transmitted bacterial, enteric, protozoan, and systemic infections-including HIV and mpox-have been steadily increasing among cisgender and transgender MSM. Despite often having similar clinical presentations, these infections have different incubation periods and testing approaches and must be ruled out effectively to guide diagnosis and treatment for MSM-identifying patients who present with symptoms of various conditions. Clinical information and screening recommendations, however, are often found in multiple guidelines rather than in a single source, thus further complicating these clinical encounters. This document provides a consolidated set of evidence and recommendations for STI testing in MSM. Testing approaches for STIs should be comprehensive and based on the patient's reported risk factors and clinical presentation. Where ongoing STI risk is identified and negative laboratory test results are received, MSM should also be counselled on recommendations for repeat screening and HIV prevention services, such as preexposure prophylaxis.

Improving awareness and uptake of pre-exposure HIV prophylaxis amongst service users accessing Sexual Health London, a regional online postal sexually transmitted infection testing health service.

The UK pledged commitment to the global strategy of zero new HIV infections and HIV-related deaths by 2030. PrEP was commissioned in England in 2020 and is fundamental to achieving these targets, yet awareness and uptake are suboptimal in certain populations. Sexual Health London (SHL) incorporated questions on its e-triage questionnaire estimating need for PrEP amongst online service users. Two types of signposting messaging were shown to users directing them to more detailed online content: PrEP-discussion (potential need) and PrEP-eligible (assumed need). The effectiveness of this signposting was evaluated by reviewing demographics and triage responses in returning users. 426,149 SHL users requested STI screening between 1.7.21-31.10.22. 16% (69,867/426,149) and 32.2% (137,489/426,149) of individuals received PrEP-eligible and PrEP-discussion signposting. The PrEP-eligible cohort were: 41.0% gay/bisexual or other men who have sex with men (GBMSM), 16.3% heterosexual males, 33.1% heterosexual females, and 60.6% were of white ethnicity. The PrEP-discussion cohort were: 9.3% GBMSM, 34.3%% heterosexual males, 45.5% heterosexual females and 63.7% of white ethnicity. 50.4% (35,190/69,867) and 41.3% (56,808/137,489) of the PrEP-eligible and PrEP discussion cohorts ordered a subsequent SHL STI testing kit, during which 10.0% (3510/35,190) and 5.9% (3364/56,808) reported taking PrEP. Of those who denied taking PrEP, 59% (18,702/31,680) and 61.0% (32,559/53,444) triggered PrEP signposting again. 95.4% of PrEP starters were GBMSM (6562/6874) and 1.4% (97/6874) heterosexual males/females. The e-service demonstrated feasibility in estimating PrEP need and signposting service users. Up to 16% of returning users subsequently commenced PrEP. This highlights significant missed opportunities for the remaining online users, who continue to report HIV acquisition risk(s). Further efforts regionally/nationally to optimise uptake of PrEP, particularly among under-represented groups are warranted.

Digital Triage Tools for Sexually Transmitted Infection Testing Compared With General Practitioners' Advice: Vignette-Based Qualitative Study With Interviews Among General Practitioners.

Digital triage tools for sexually transmitted infection (STI) testing can potentially be used as a substitute for the triage that general practitioners (GPs) perform to lower their work pressure. The studied tool is based on medical guidelines. The same guidelines support GPs' decision-making process. However, research has shown that GPs make decisions from a holistic perspective and, therefore, do not always adhere to those guidelines. To have a high-quality digital triage tool that results in an efficient care process, it is important to learn more about GPs' decision-making process. The first objective was to identify whether the advice of the studied digital triage tool aligned with GPs' daily medical practice. The second objective was to learn which factors influence GPs' decisions regarding referral for diagnostic testing. In addition, this study provides insights into GPs' decision-making process. A qualitative vignette-based study using semistructured interviews was conducted. In total, 6 vignettes representing patient cases were discussed with the participants (GPs). The participants needed to think aloud whether they would advise an STI test for the patient and why. A thematic analysis was conducted on the transcripts of the interviews. The vignette patient cases were also passed through the digital triage tool, resulting in advice to test or not for an STI. A comparison was made between the advice of the tool and that of the participants. In total, 10 interviews were conducted. Participants (GPs) had a mean age of 48.30 (SD 11.88) years. For 3 vignettes, the advice of the digital triage tool and of all participants was the same. In those vignettes, the patients' risk factors were sufficiently clear for the participants to advise the same as the digital tool. For 3 vignettes, the advice of the digital tool differed from that of the participants. Patient-related factors that influenced the participants' decision-making process were the patient's anxiety, young age, and willingness to be tested. Participants would test at a lower threshold than the triage tool because of those factors. Sometimes, participants wanted more information than was provided in the vignette or would like to conduct a physical examination. These elements were not part of the digital triage tool. The advice to conduct a diagnostic STI test differed between a digital triage tool and GPs. The digital triage tool considered only medical guidelines, whereas GPs were open to discussion reasoning from a holistic perspective. The GPs' decision-making process was influenced by patients' anxiety, willingness to be tested, and age. On the basis of these results, we believe that the digital triage tool for STI testing could support GPs and even replace consultations in the future. Further research must substantiate how this can be done safely.
