Screening for sexually transmitted infections (STIs) in the emergency department (ED) is limited by the need for pelvic examination. It has been suggested that using self-administered vaginal swabs (SAVS) for this purpose may save time and resources and may be more comfortable for patients. Objectives: The objective was to test the feasibility of using SAVS for STI screening in the ED.


This was a prospective study of female ED patients 18 to 55 years old who consented to physician-assisted cervical swab (PACS) and SAVS in two urban teaching hospitals. The ED personnel offered the test to all patients, whether or not a pelvic examination was indicated, based on their chief complaint. All specimens were analyzed by polymerase chain reaction (PCR) assay. Data are presented as mean +/- standard deviation (SD). Categorical data are presented as percentages with 95% confidence intervals (CIs). Patients with a positive test result for Chlamydia trachomatis and/or Neisseria gonorrhoeae were considered positive for STI. PACS were used as the criterion standard.


One-hundred sixty-two subjects were enrolled from July 2006 to July 2007 (mean [+/-SD] age = 32 [+/-10] years). Eighty-one percent of patients had a genitourinary symptom (most common: vaginal bleeding/spotting). SAVS had a sensitivity of 91% (95% CI = 60% to 99%), specificity of 99% (95% CI = 95% to 99%), positive likelihood ratio of 91, and negative likelihood ratio of 0.09 in diagnosing STIs. None of the patients reported difficulty or discomfort using this technique.


Self-administered vaginal swabs can be utilized as a feasible alternative to PACS for STI screening in the ED.
