Use of a Rapid Diagnostic for Chlamydia trachomatis and Neisseria gonorrhoeae for Women in the Emergency Department Can Improve Clinical Management: Report of a Randomized Clinical Trial
Abstract
Study objective: In emergency departments (EDs), diagnosis and treatment of Chlamydia trachomatis and Neisseria gonorrhoeae are challenging. We conducted a randomized clinical trial to assess rapid C trachomatis and N gonorrhoeae testing on overtreatment and undertreatment of women evaluated for C trachomatis and N gonorrhoeae. Methods: Women undergoing pelvic examinations and C trachomatis and N gonorrhoeae testing (n=254) were randomized to control or rapid test groups. The control group received standard-of-care C trachomatis and N gonorrhoeae nucleic acid amplification tests of endocervical specimens, with 2- to 3-day turnaround times. For the rapid test group, clinicians collected an extra endocervical swab for GeneXpert C trachomatis and N gonorrhoeae rapid testing, in addition to the standard-of-care nucleic acid amplification test swab. Rapid results were immediately provided, and all patients were treated according to providers’ clinical judgment. Results: In the rapid test group, 7.9% of patients had positive test results for C trachomatis; 3.9% had positive test results for N gonorrhoeae. In the control standard-of-care group, 10.2% of patients had positive nucleic acid amplification test results for C trachomatis; 5.5% had positive results for N gonorrhoeae. Undertreatment for both C trachomatis and N gonorrhoeae in the ED was 0% for the rapid test group and 43.8% for the control standard-of-care group. Clinicians overtreated 46.5% of uninfected standard-of-care…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 254 participants or records.
