Harm reduction and multidisciplinary consultations for gay, bisexual, and other men who have sex with men practising chemsex based in a French infectious disease unit: patients' characteristics and perceptions.

ABSTRACT

BACKGROUND: Chemsex, a type of sexualised drug use, is expanding among gay, bisexual, and other men who have sex with men (GBMSM), with physical and mental health risks. Health-seeking behaviours of GBMSM practising chemsex is not clear. METHODS: Harm reduction (HR) consultations for GBMSM engaging in chemsex and seeking comprehensive services including HR were offered in a Parisian infectious disease unit. From December 2021 to January 2022, HR consultation patients completed an online survey on their consumption, health, used services, and perspective on consultations. We generated descriptive statistics, and tested (χ 2 ) the relationship between reporting a specialised follow-up and perceived usefulness of intervention. RESULTS: Of 172 patients, a total of 96 GBMSM (55.2%) completed the survey. Most ever consumed substance was 3-methylmethcathinone (3MMC; 92/96; 95.8%). Before consultations, about half consumed at least once a week (50/96; 52%), most reported negative impacts of chemsex on their social (60/96, 62.5%), professional (56/96, 58.3%), intimate (53/96; 55.21%), or sexual life (52/96; 54.17%). Also, more than two-thirds (n =57; 69.38%) had received a follow-up in specialised services one-third had been followed in addictology (28/96, 29.2%) and/or psychotherapy (32/96, 33.3%), and one-fourth (24/96, 25.0%) had used emergency services. After consultations, three-quarters perceived the intervention as useful (n =74; 77.08%); we found no significant relationship with receiving a specialised follow-up; and most were satisfied with professionals' listening (90/96; 93.8%), and reported reduced risks (80/96; 83.3%). DISCUSSION: Multidisciplinary HR, preventive, diagnostical, and therapeutic sexological and psychiatric interventions are greatly needed among GBMSM practising chemsex. HR interventions accessible in services already attended by GBMSM are a valuable option.
