Abstract Aims Methods Women aged 18-44 years presenting to ASC were offered a voluntary self-collected high vulvovaginal swab for chlamydia and gonorrhoea at triage. Data was collected over one year (Dec 2021-Dec 2022). Testing was offered to 299 patients, 20 declined to participate and 18 samples were rejected. Positive results were referred to the Sexual Health service for treatment and contact tracing as agreed on a pre-planned referral pathway. Results 5.4% of swabs were positive (2 Gonorrhoea and 12 Chlamydia). The mean age of those testing positive was 24.5. All positive patients presented initially with lower abdominal pain. Of those testing positive 7 had further imaging (USS pelvis) and only 25% had a documented sexual history taken. 4 women had diagnostic imaging indicative of PID and 4 patients were treated for PID empirically. The remaining patients were treated for non-specific abdominal pain or unrelated pathology. Conclusions Undiagnosed sexually transmitted disease is prevalent and young females presenting with lower abdominal pain provide an excellent testing cohort. Given the high incidence of positive tests, further training of surgeons to consider and ask pertinent questions regarding an STI diagnosis is vital. The introduction of self-swab testing has been successful in assisting as a diagnostic tool and screening programme.
