A pilot study evaluated the yield of testing patients for other STIs among patients with genital chlamydia diagnosed during opportunistic screening. The study screened patients of both sexes in primary health care settings, as well as men attending a genitourinary medicine clinic. All patients testing positive in the community were advised to attend the genito-urinary medicine clinic for STL screening, partner notification, and testing of patients and their contacts. More than 90% of the patients testing positive for chlamydia attended the genitourinary medicine clinic for management (total numbers seen in the clinic; women n=1245 [957 screened in the community] and men n=490 [280 screened in the community]). At the clinic, further workup included evaluation and testing for chlamydia, gonorrhea, trichomonas, and bacterial vaginosis. Of the patients whose initial screening was in the genitourinary medicine clinic, 28% had an additional STL Of the patients initially screened in the community setting, 4% had another STI. Partner testing showed that 55% of male partners of female patients had an STI and 76% of female partners of male patients had one or more STI. The high prevalence of coinfection of chlamydia and gonorrhea has been shown in several studies. One cross-sectional study of new clients to a hospital-based STI clinic with gonorrhea, chlamydia, or both infections found 39% of 1239 women and 24% of 1141 heterosexual men with gonorrhea also had chlamydia. Thirteen percent of females and 19% of heterosexual males with chlamydia also had gonorrhea. More than half of the women and a third of the men aged 15 to 19 had both gonorrhea and chlamydia. Patients with both STIs tended to be younger than those with one. A study of the prevalence rate of chlamydia, gonorrhea, and their coinfection in an adolescent population (women n=131,915 and men n=71,074) of juvenile detention centers between 1997 and 2002 found that 18% of women and 13% of males with chlamydia were coinfected with gonorrhea. In non-STI clinic settings, gonorrhea has been found in 9% of men and 6% of women with chlamydia.
