Frequency of Injuries to Women after Sexual Offense - Relevance of a Gynecology Examination

Introduction Up to a third of women worldwide report having experienced an act of sexual violence during their lifetime. The emergency gynecology department is often the first port of call for affected individuals. The aim of the current study was to evaluate the importance of gynecology examinations for women after a sexual offense and to evaluate the pattern of injuries sustained. Methods This study is a retrospective single center analysis of the gynecology and forensic examination reports of all women examined for a suspected sexual offense in the central emergency department of a university hospital between 2013 and 2017 (n = 692). We evaluated genital and extragenital injury patterns, age, offender profile, time of offense, and substance use, as well as the administration of post-coital contraception and post-exposure prophylaxis for HIV. Results The affected individuals had a mean age of 26 (12-91 years). Almost 75% of affected individuals presented within 24 hours of the reported sexual offense. Extragenital injuries were detected in 78.6% of patients and genital injuries in 28.5%. Overall, 20.1% of the women reported complete memory loss and 18.7% partial memory loss of the actual event. Risk factors for memory lapse were the consumption of alcohol and/or the (possibly non-consensual) administration of other substances acting on the central nervous system. A history of alcohol consumption by the victim (hazard ratio [HR] 1.95; 95% confidence interval [CI] 1.21-3.12, p = 0.006) and younger victims aged between 25-49 years (HR 1.75; 95% CI 1.07-2.85, p = 0.025) were associated with the occurrence of extragenital injuries. However, if the perpetrator was someone who was known to the affected individual, fewer extragenital injuries were sustained (HR 0.60; 95% CI 0.36-0.99, p = 0.046). Reports of genital injuries, associated with an older age of affected individuals and indications of anal penetration, resulted in more frequent administration of post-exposure prophylaxis (29.1% vs. 19.5%, p < 0.012) and hepatitis B (active) vaccination (40% vs. 28.5%, p < 0.028). Conclusion Emergency gynecology examinations form a fundamental component of the medical care and the assessment of affected women after a sexual offense, since almost a third of victims sustain injuries to the genital region. In addition to a detailed complete physical examination and expert forensic documentation of physical and genital injuries, victims should also be offered psychological support which is easy for them to access.
