Feasibility of anorectal chlamydia testing in women: a cross-sectional survey among general practitioners

Abstract

Abstract Background Anorectal Chlamydia trachomatis (CT) may be clinically relevant for women in general practice. Although anorectal CT testing in this setting may prevent underdiagnosis and undertreatment, its feasibility is questioned as GPs currently rarely order anorectal CT tests, for yet unknown reasons. Objective To explore the feasibility of anorectal CT testing in women in general practice. Methods GPs across the Netherlands were invited directly (n = 1481) and by snowball sampling (n = 330) to join an online cross-sectional survey that asked about the acceptability of and barriers for (standard) anorectal testing in women during CT-related consultations. Data were analysed with univariable and multivariable logistic regression models. Results The questionnaire was opened by 514 respondents (28%, 514/1811) and 394 fully completed it. GPs’ acceptability of anorectal testing by either self-sampling or provider-sampling was high (86%). Twenty-eight percent of GPs felt neutral, and 43% felt accepting towards standard anorectal testing. Nevertheless, 40% of GPs had never tested for anorectal CT in women, which was associated with a reported difficulty in asking about anal sex (odds ratio [OR]: 3.07, 95% confidence interval [CI]: 1.21–7.80), infrequency of anal sexual history taking (OR: 11.50, 95% CI: 6.39–20.72), low frequency of urogenital CT testing (OR 3.44, 95%-CI: 1.86–6.38) and with practicing in a non-urban area (OR: 2.27, 95% CI: 1.48–3.48). Acceptability of anorectal testing was not associated with the studied factors. Conclusion This quantitative survey shows that anorectal CT testing is feasible based on its acceptability, but is likely hindered by a lower awareness of (anorectal) CT in GPs.
