Pediatrics: Original ContributionsOpportunistic urine ligase chain reaction screening for sexually transmitted diseases in adolescents seeking care in an urban emergency department*,**,★
Introduction
Infections caused by Neisseria gonorrhoeae and Chlamydia trachomatis are the 2 most common reportable infectious diseases in the United States.1 Asymptomatic infections are relatively common, and although rates of these infections are highest in sexually active adolescents, their sequelae (ie, infertility, ectopic pregnancy, and chronic pelvic pain) may only become apparent years later.1, 2 Thus, interventions to promote diagnosis and treatment of these common bacterial sexually transmitted diseases (STDs) are a public health priority.
Screening of at-risk adolescents for STDs is recommended; however, health care opportunities for this group are limited. Previous studies have shown that adolescents, irrespective of the site of care, seldom receive comprehensive office-based health care.2, 3, 4 Instead, they most often present and are seen for brief, problem-oriented visits.2, 3, 4 Access to reproductive health care may be particularly difficult for this group. Barriers for seeking reproductive health care by young people include lack of STD symptom recognition, lack of knowledge regarding how to access care, lack of adequate insurance coverage, and concerns about confidentiality.3, 5, 6 For many adolescents, more so than for any other age group, the sole source of medical care is problem-oriented care provided in an acute care setting such as EDs.3, 4
Recently, diagnostic testing for gonorrhea and chlamydial infection using nucleic acid amplification technologies such as ligase chain reaction has become available; these tests provide a sensitive and specific diagnosis while also permitting simplification of specimen collection.7, 8, 9, 10 In a pilot study to evaluate the prevalence of treatable bacterial STDs in a readily accessible, potentially underserved adolescent population, we used ligase chain reaction testing on urine specimens of adolescents attending an urban ED to determine the prevalence of N gonorrhoeae and C trachomatis infections.

Materials and methods
This study was conducted in an ED of an urban, inner-city children’s hospital. More than 50,000 ED visits are recorded annually with more than 7,000 adolescents seen each year. A convenience sample of adolescents presenting for care at the ED between March 1997 and June 1998 were subjects of this pilot project. The protocol was approved by the Institutional Review Board for Human Subject Use. The usual emergency medicine clinical assessment and standard of care was not altered by this study
Results
The median age of study participants was 16 years. Of the 282 patients evaluated, 193 (68%) were female. Typical of patients seen in the ED and reflective of the demographic characteristics of metropolitan Birmingham, 203 (72%) of the study population were black patients. One hundred twenty (42%) of the patients had private insurance, 62 (22%) were covered by Medicaid, and 100 (36%) reported no health care insurance.
The chief complaints of participants were typical of adolescents seeking urgent
Discussion
Adolescents are an important target population in STD control efforts in the United States. Compared with other age groups, sexually active youths ages 16 to 19 years have the highest C trachomatis rates and the second highest N gonorrhoeae rates,1, 2 more often have asymptomatic infections,2, 5, 11, 12 and tend to have more limited access to health care.13, 14, 15 In addition, as gonorrhea rates have declined in recent years and as rates of chlamydial infection have begun to plateau, these
