Increasing demand for specialist care regarding chemsex
The Institute of Tropical Medicine Antwerp (ITM) is launching a specialised centre of expertise for chemsex. With this new interdisciplinary care and research programme, ITM aims to support people who use drugs in a sexual context and experience physical, mental or social problems as a result. The centre builds on years of experience with care and research into sexual health.
The phenomenon of chemsex
Chemsex involves taking specific drugs before or during sex, often in the context of prolonged sessions with multiple partners, which increases health risks. It has been most frequently studied among men who have sex with men (MSM). A recent article (1) by Georgiadis et al. shows that, worldwide, 22% of MSM have experience with chemsex. The figures are compiled from 238 studies involving a total of 380,505 participants. For at least five of the substances, the figures in Europe were consistently the highest in the world.
"For many people who engage in chemsex, it remains difficult to find appropriate support," says Tom Platteau, a sexologist at ITM. "Support services often focus solely on sex or solely on substance use, whereas it is precisely the combination of these factors that is crucial to providing people with effective support. With this centre, we aim to bridge that gap."
ITM: a trusted place for the target group
ITM has maintained close contact with the target group for many years, including MSM who consult the institute for PrEP and HIV follow-up. "We see people experiencing negative consequences, but also people who are motivated to make a change," says Platteau. "That makes it crucial to link care and research and to ensure that support is grounded in reality."
The new centre of expertise provides a point of contact for support relating to chemsex and other forms of sexualised drug use. People can access the service by booking an appointment, even if they are not receiving treatment elsewhere at ITM. The multidisciplinary team has specific expertise in substance use, sexual health, mental health and social support, and works together to provide the best possible care. This care is always delivered in a respectful, non-judgemental and person-centred manner.
To be able to provide high-quality care, scientific research is also conducted within the centre. This research will always be directly aimed at improving care for clients.
Collaboration
ITM collaborates with care partners such as Sensoa, the Flemish Expertise Centre for Alcohol and Other Drugs (VAD) and the University Hospital of Ghent (UZ Gent), and consults with policy-makers such as the Care and Health Agency and the National Institute for Health and Disability Insurance (RIZIV). There is also demand for support and expertise from the target group.

Science, healthcare and the community come together
How can researchers, healthcare providers, community organisations and people with personal experience work together to improve care and support? That was the central question during the International Chemsex Conference, organised by ITM from 3 to 5 March. Over three days, 242 participants from 25 countries exchanged research findings, practical experiences and ideas. "Chemsex is an international phenomenon," said Tom Platteau. "By sharing knowledge and experiences, we enhance the quality and humanity of care for people affected by this."
