Characteristics of (Unwanted) Use of Alcohol and Illicit Substances Among Patients Reporting After Sexual Violence in Ghent: a Mono-centric Prospective Observational Study

This study aims to map (un)voluntary use of alcohol and drugs among victims of sexual violence who present to the Care Centre after Sexual Violence at UZ Gent, referred to in English as Drug-Facilitated Sexual Assault (DFSA).

Sometimes substances are deliberately used to render a victim submissive (proactive DFSA), but it is also possible that people use substances themselves recreationally and later become victims of sexual violence (opportunistic DFSA).

Recent media reports of drinks in which psychogenic substances are involuntarily administered have become more frequent, after which people sometimes become victims of sexual violence. The public attention for this problem increased significantly recently. However, no clear data are currently available in Belgium on this problem.

Using a prospective observational study, we aim to map the incidence of (unwanted) use of alcohol and illegal substances among victims who report to the Care Centre after Sexual Violence in Ghent. The data - after obtaining informed consent - will be collected by means of (nurse-led) questionnaires and toxicological analyses on blood and urine samples. We envisage a two-year period for inclusion of patients, starting from 01/03/2023, running until 31/03/2025.

With these results, we want to estimate the proportion of sexual assault incidents in which the victim was incapacitated by voluntary or involuntary/unwanted use of alcohol or illicit substances (e.g. cannabis, GHB, cocaine, ...). To this end, we need to record data from all patients who present in order to estimate the denominator.
