Risky sexual behaviors reported by patients in a free sexual health center in Paris (2017-2020)

Background

In France, a national network of free sexual health centers offers prevention, diagnosis and treatment for STI and HIV. These centers help socially disadvantaged and high-risk populations to access STI/HIV testing but few detailed data are available on patients' sexual behaviors. This study aims to describe sexual behaviors among attendees of a Parisian free sexual health center for STI/HIV screening.

Methods

This observational study included 5130 patients who attended the center for STI/HIV testing from August 2017 through January 2020 and completed a self-administered electronic questionnaire. Data obtained from the consultation database and the questionnaire included STI results, sociodemographic characteristics and sexual behaviors. Criteria reported in the literature to define “high-risk sexual behavior (HRSB)” were used to describe sexual practices.

Results

Median age of patients was 26 years [Q1-Q3:23-32] and 8% had no health insurance. Slightly less than one third of patients were women who had sex with men, 37% were men who had sex exclusively with women and 18% were men who had sex with men; 22% had never had HIV testing before the consultation. Regarding sexual practices, 76% reported unprotected sexual intercourse, 3% transactional sex and 8% a history of sexual violence. Depending on the threshold used to define multiple partners (≥6 vs ≥ 2 partners during the previous year), the proportion of patients varied from 31% to 81%. Globally, the proportion of patients reporting at least one HRSB ranged from 87% to 95%. Eleven percent of patients had at least one STI (mostly chlamydia).

Conclusions

Our sexual health center fulfills its missions as most patients consulting for STI/HIV testing reported HRSB and almost one quarter had never previously had an HIV test. The next step will be to explore profiles including sexual behavior, sociodemographic characteristics and HIV knowledge to adapt our prevention strategy to patients' needs.

Key messages

Our sexual health center fulfills its missions as most patients consulting for STI/HIV testing reported HRSB and almost one quarter had never previously had an HIV test. The next step will be to explore profiles including sexual behavior, sociodemographic characteristics and HIV knowledge to adapt our prevention strategy to patients’ needs.

Effectiveness among MSM of an HIV PrEP program developed in a Parisian sexual health center

Background

HIV pre-exposure prophylaxis (PrEP) is highly effective but depends on patients' adherence and follow-up. To enhance follow-up quality and care engagement, the PrEP program developed in our Parisian sexual health center offers accompanying measures throughout the patients' course of care, relying notably on an identified and easily accessible referent. This trained paramedic counselor in sexual health provides support in organizing appointments, phone and email follow-up to answer daily questions, as well as one-on-one sessions of therapeutic support and counseling. This study aimed to assess the effectiveness of such a PrEP program among men who have sex with men (MSM).

Methods

This retrospective observational study included all MSM who initiated PrEP for the first time between 1 August 2018 and 30 June 2019 in the Fernand-Widal hospital sexual health center, Paris, France. Sociodemographic characteristics, sexual practices including very high risk situations (chemsex practice and/or sexually transmitted diseases at initiation and/or history of post-exposure prophylaxis [PEP]) and course of care during the first year were described. A novel metric developed by Hendrickson et al., the PrEP success ratio at 12 months, was used to assess effectiveness of PrEP.

Results

Among the 125 MSM included in this study, the median age was 33 and most had only male partners. At initiation, 58% were considered at very high risk of HIV infection, mainly due to a history of PEP. During the first year, patients attended a median of 3 visits (Q1-Q3, 2-4). At 12 months, 96% (95% CI, 92.6 to 99.4) of patients had a successful PrEP course, with no reported seroconversion.

Conclusions

This experiment highlights the possibility of achieving a high PrEP success ratio among MSM in a real-world setting. The accompanying measures set up in our sexual health center could explain the effectiveness of our PrEP program in comparison with previous studies.

Key messages

In a Parisian sexual health center that developed an HIV PrEP program with a trained paramedic counselor in sexual health, 96% of MSM achieved a successful PrEP course at 12 months. Accompanying measures for PrEP users could play a key role in achieving high PrEP success among MSM.

What do patients consulting in a free STI center know about HIV transmission and prevention?

Background

Despite therapeutic progress, HIV remains a public health issue with about 6400 new HIV contaminations each year in France. HIV prevention relies on health education, early screening, treatment as prevention, post and pre-exposure prophylaxis. Patients’ visits to free sexually transmitted infections (STIs) screening centers (CeGIDD) are opportunities to spread prevention messages. This study aimed to assess level of HIV knowledge in a Parisian CeGIDD to improve prevention messages.

Methods

The study included patients older than 18 who came for STIs testing between August 2017 and August 2018 and who understand written French language. Data were collected by a self-administered electronic questionnaire filled in before medical consultation. It included sociodemographic data and knowledge regarding HIV transmission and prevention.

Results

The study included 2002 patients. The median age was 27 years and 66% were men. More than 96% of patients know that HIV transmission is possible through unprotected sexual intercourse and through needle exchange. However, some misconceptions persist: 20% of patients believe that HIV transmission is possible from using public toilets and 22% by mosquito bite. Prevention measures perceived as “absolutely or rather efficient” by patients were: using condom (97%), requesting a screening test from his partners (91%), getting screening tests regularly (90%), choosing his partners correctly (62%), having sex with few different partners (50%). Half of patients heard of post-exposure prophylaxis (51%).

Conclusions

Main modes of HIV transmission are well known (unprotected intercourse and needle exchange). However, false beliefs regarding prevention may lead to risk behavior (doing screening test regularly doesn’t protect against HIV) and need to be explored. Moreover, assessment of variation in level of HIV knowledge according to patient’s profile may help to target prevention message according to specific populations.

Key messages

Main modes of HIV transmission are well known. False beliefs regarding modes of prevention need to be explored to target HIV prevention messages.

How to reach migrant transgender women in Paris? An example of collaborative sexual health action

Issue

In France, screening for HIV and sexually transmitted infections (STIs) is provided by free HIV and STIs screening centers called CeGIDD. Despite a complete combined prevention offer, the number of new HIV diagnosis has been stable for years. Transgender women have one of the highest HIV prevalence.

Description of the problem

Transgender women are a hard to reach population with multifactorial barriers in their access to healthcare including fear of stigma, leading to late HIV diagnosis and untreated STIs. The CeGIDD of a university hospital in Paris aimed to reach this public working with two associations, creating a free, complete sexual health action outside the hospital in a safe environment.

Results

The CeGIDD identified a Parisian association, PASTT, which accompanies transgender women, mainly migrants, in accessing healthcare and social rights. Its active file is around 1500 persons a year, mostly resorting to prostitution. Another association, AREMEDIA, pioneer in outreach interventions, was involved. The partnership allowed access to the public and to gather the funds for the intervention. It included counseling, screening, Pre Exposure Prophylaxis (PrEP), and took place once a week in PASTT facilities. Any participant could be referred to other physicians if they needed it, even if they lacked health insurance coverage. From September 2017 to November 2018, 212 persons attended the consultation and 26 received PrEP.

Lessons

Working together with several associative partners presents many challenges, from the definition of the objectives to operational coordination. Overcoming these difficulties lead us to reach a new public with a high risk for STIs and HIV.

Key messages

Community based sexual health actions dedicated to transgender women are a successful way to reach this public. The safe environment provided by the association is a great opportunity to familiarize them with the medical staff and to empower them regarding healthcare.

[Raman spectroscopy applied to analytical quality control of injectable drugs: analytical evaluation and comparative economic versus HPLC and UV / visible-FTIR]

In France, central IV admixture of chemotherapy (CT) treatments at the hospital is now required by law. We have previously shown that the shaping of Therapeutic Objects (TOs) could profit from an Analytical Quality Assurance (AQA), closely linked to the batch release, for the three key parameters: identity, purity, and initial concentration of the compound of interest. In the course of recent and diversified works, we showed the technical superiority of non-intrusive Raman Spectroscopy (RS) vs. any other analytical option and, especially for both HPLC and vibrational method using a UV/visible-FTIR coupling. An interconnected qualitative and economic assessment strongly helps to enrich these relevant works. The study compares in operational situation, the performance of three analytical methods used for the AQC of TOs. We used: a) a set of evaluation criteria, b) the depreciation tables of the machinery, c) the cost of disposables, d) the weight of equipment and technical installations, e) the basic accounting unit (unit of work) and its composite costs (Euros), which vary according to the technical options, the weight of both human resources and disposables; finally, different combinations are described. So, the unit of work can take 12 different values between 1 and 5.5 Euros, and we provide various recommendations. A qualitative evaluation grid constantly places the SR technology as superior or equal to the 2 other techniques currently available. Our results demonstrated: a) the major interest of the non-intrusive AQC performed by RS, especially when it is not possible to analyze a TO with existing methods e.g. elastomeric portable pumps, and b) the high potential for this technique to be a strong contributor to the security of the medication circuit, and to fight the iatrogenic effects of drugs especially in the hospital. It also contributes to the protection of all actors in healthcare and of their working environment.
