Background Neisseria gonorrhea (NG), Chlamydia trachomatis (CT), and Trichomonas vaginalis (TV) are common sexually transmitted infections (STIs) treated in the emergency department (ED). Objectives To assess the history, physical examination, and laboratory findings associated with NG and CT infection and the decision to administer empiric antibiotic treatment for the diseases in the ED. Methods A retrospective review of 566 clinical encounters of adult female patients tested for STIs between January 1, 2013 and December 31, 2014. An analysis of patient-and provider-level variables was assessed to determine the characteristics associated with empiric antibiotic treatment in the ED and post-discharge laboratory confirmed NG or CT. Results Younger age and the presence of TV on vaginal wet prep had a higher association with being infected with NG or CT (p < 0.05). Subjective exam findings, such as vaginal discharge, abdominal pain, urinary urgency, urinary frequency, dysuria, objective vaginal discharge, cervical motion tenderness, adnexal tenderness, vaginal bleeding, as well as positive leukocyte esterase and nitrites on urinalysis were all not associated with NG or CT infection (p > 0.05). ED providers were more likely to treat subjects in the ED for NG and CT when there was subjective and objective vaginal discharge, cervical motion tenderness, adnexal tenderness, and vaginal bleeding, TV on wet prep, and leukocyte esterase on urinalysis (p < 0.05). Conclusions Only younger age women and the presence of TV on vaginal wet prep were associated with NG 1 2 3 4 5 1 5
Demographic characteristics, risk factors, and clinical variables associated with gonorrhea and chlamydial infection in women being treated in emergency departments (EDs) in the United States are incompletely characterized. We used univariable and multivariable regression analyses on 17,411 encounters from women 18 years and older who presented to EDs in northeast Ohio and were tested for gonorrhea or chlamydial infection. There were 1,360 women (7.8%) who had Chlamydia trachomatis infection and 510 (2.9%) who had Neisseria gonorrhoeae infection. Those infected with C. trachomatis or N. gonorrhoeae were younger (23.8 vs. 29.2 years), unmarried (97.7% vs. 90.1%), Black (93.3% vs. 88.0%), infected with Trichomonas vaginalis (39.9% vs. 27.2%), diagnosed with urinary tract infection (15.7% vs. 10.6%), and treated for gonorrhea and chlamydial infection during the ED visit (31.6% vs. 17.4%) (all ps < .001). Women infected with C. trachomatis or N. gonorrhoeae had more urine white blood cells (WBCs) (23.9 vs. 16.4 cells per high-power field [HPF]) and leukocyte esterase (1.2+ vs. 0.8+) on urinalysis. They had more WBCs (18.5 vs. 12.4 cells/HPF) and odds of having T. vaginalis infection (12.8% vs. 8.2%) on vaginal wet preparation (all ps < .001). Women infected with C. trachomatis were more likely to be younger and not Black; they were less likely to be treated for gonorrhea and chlamydial infection in the ED and to have lower levels of urine WBCs, leukocyte esterase, and blood than those infected with N gonorrhoeae (all ps ≤ .05).
