ABSTRACT
The objective of this study was to explore whether patients with Chlamydia trachomatis infection who self-refer to genitourinary medicine clinics have different demographic characteristics to those who initially attend other agencies. This study took place in three genitourinary medicine clinics from Birmingham, Nottingham and Sheffield. Demographic and post-code data were collected from female patients diagnosed with genital chlamydia infection in 2000. Townsend scores, as an index of socioeconomic status, were derived from post-codes from a subset of the cohort (from Birmingham). Comparison was made between those who were diagnosed by genitourinary medicine clinics and those diagnosed in the community and referred to genitourinary medicine clinics for further management. Data were collected from 1047 genitourinary medicine and 816 non-genitourinary medicine women, of whom 686 (84.1%) attended genitourinary medicine clinics following referral. After excluding those with incomplete data, 1614 (987 genitourinary medicine and 627 non-genitourinary medicine) patients were included in the study. Using logistic regression analysis, we were unable to demonstrate any significant differences in age or Townsend scores between genitourinary medicine and non-genitourinary medicine patients. However, significantly more Black Caribbean (odds ratio [OR] = 2.72, 95% confidence interval [CI]: 2.22, 3.20) and single women (OR = 1.97, 95% CI: 1.64, 2.29) self-referred to genitourinary medicine clinics compared with other health-care settings. This trend was consistent between Birmingham and Nottingham. In Sheffield, there was no difference in marital status. Ethnicity was not a factor as there were no Black Caribbean patients in the Sheffield cohort. Women who were diagnosed with genital chlamydia infection in genitourinary medicine clinics have some different demographic characteristics to those who were diagnosed in the community.
