BACKGROUND: Because patients infected with Neisseria gonorrhoeae are frequently coinfected with Chlamydia trachomatis, routine dual treatment of patients with N gonorrhoeae infection is frequently practiced and has long been recommended. GOAL: The goal of this study was to examine the cost-effectiveness of routine dual treatment of women with infection, with or without separate testing for C trachomatis, compared with an alternative of testing for both infections and restricting treatment for C trachomatis to women testing positive for C trachomatis. STUDY DESIGN: A decision analysis compared the cost-effectiveness of these options using cases of pelvic inflammatory disease prevented as the outcome. Parameter values were taken from the literature. RESULTS: Routine dual treatment is not an effective or cost-effective replacement for testing for C trachomatis, but it can increase the number of cases of C trachomatis treated when combined with testing. Dual treatment results in more overtreatment of infection C trachomatis than treatment based on test results. CONCLUSIONS: Testing for both infections is more cost-effective than routine presumptive treatment for C trachomatis. Providing both presumptive treatment and testing for C trachomatis can also be cost-effective in some settings.
