Sexually transmitted infection prevalence in symptomatic adolescent emergency department patients

Ten-Year Trend in Emergency Department Visits for Sexually Transmitted Infections among Adolescents: A Retrospective Cross-Sectional Study in Italy

Sexually transmitted infections (STIs) are frequently underdiagnosed, representing a serious public health concern, especially during adolescence and in more vulnerable communities.

AIM

to describe the last ten years of emergency department (ED) visits for STIs among adolescents.

METHODS

a retrospective cross-sectional observation was carried out in the Piedmont region in Italy. Data were retrieved through the Italian National Information System database. ED visits related to specific ICD-9-CM codes carried out on 11 to 19-year-old youths between 2011 and 2020 were investigated. Age-specific, crude, and standardized rates and admission ratios, with 95% confidence intervals (CIs), were calculated to estimate the STI trend.

RESULTS

from a total of 1,219,075 ED visits, 339 were related to STIs, representing an increasing ratio of 28 per 100,000 visits, primarily in females. Most infections occurred in girls (83.5%) and among 17 to 19-year-olds (71.5%). A drop in both ED visits and STI cases was observed in 2020. Genital Herpes and Genital Warts were more frequent in girls while Gonorrhea was more frequent in boys.

CONCLUSIONS

the increasing trend of ED visits for STIs, particularly in girls, represents an emerging relevant public health issue that needs to be urgently tackled.

Impact of Rapid Testing for Gonorrhea and Chlamydia in an Urban Pediatric Emergency Department

PURPOSE

To determine the impact of rapid testing for gonorrhea (NG) and chlamydia (CT) on accuracy of treatment in adolescents in the pediatric emergency department (ED).

METHODS

Retrospective study of adolescents tested for NG and CT in the pediatric ED before and after implementation of rapid testing. Treatment during initial visit, availability of test results prior to discharge, and number of follow-up phone calls made with test results were compared. Appropriate treatment was defined per Centers for Disease Control and Prevention 2015 guidelines as monotherapy for CT and dual therapy for NG. Descriptive statistics were used to compare groups.

RESULTS

Rapid testing improved treatment accuracy with 522 (79.3%) patients treated appropriately in the rapid testing group compared to 478 (64.7%) patients in the batched testing group (p < .001). Inaccurate treatment was more common in the batch testing group among those who tested negative (p < .001). Among those who tested positive for NG and/or CT, phone calls were made to 54 (47.8%) patients in the rapid testing group and 129 (84.3%) patients in the batched testing group to discuss positive test results (p < .001).

CONCLUSION

Compared to batched testing, rapid testing is associated with improved accuracy of treatment of NG and CT in the pediatric ED setting. Additionally, rapid testing is associated with decreased number of phone calls to discuss positive test results.

Missed Opportunities for Sexual History Documentation and Sexually Transmitted Infection Testing in the Pediatric Emergency Department

PURPOSE

Sexually transmitted infections (STIs) are disproportionally prevalent in adolescents, and adolescents often present to the pediatric emergency department (PED) for STI care. Prior studies have found low rates of sexual history documentation and STI testing in the PED. However, these studies have had limited sample sizes because of the burden of manual chart review. We aimed to estimate the rate of sexual history documentation and identify factors associated with STI testing in a large cohort of adolescents using natural language processing (NLP).

METHODS

We applied a validated NLP algorithm to all adolescent visits over a three-year period to the PED at a single large children's health care organization with a chief complaint potentially related to an STI. We utilized NLP to determine the prevalence of sexual history documentation in these patients. We applied logistic regression models to determine associations between sexual history documentation, patient demographic factors, and STI testing.

RESULTS

Of the 1,987 patient encounters included, only 56% had a sexual history documented, and only 40% of all patients were tested for STIs. Patients were more likely to have a sexual history documented and to be tested for STIs if they were of non-Hispanic black race/ethnicity, were >15 years of age, and had nonprivate insurance. Patients with a sexual history documented were seven times more likely to have STI testing ordered. Of patients tested (n = 728), 25% were positive for an STI.

CONCLUSIONS

Despite presenting to the PED with symptoms potentially related to an STI, many adolescents are not receiving recommended sexual health care. Rates of sexual history documentation and STI testing varied by demographic factors including race, age, and insurance status. Utilizing NLP technology allowed us to examine a larger sample size than previously documented in the adolescent sexual history and PED literature. This study highlights critical opportunities to improve sexual health provision and equity of care provided in the PED.

Value of Packaged Testing for Sexually Transmitted Infections for Persons who Inject Drugs Hospitalized With Serious Injection-Related Infections

Background

Persons who inject drugs (PWID) are frequently admitted for serious injection-related infections (SIRIs). PWID are also at risk for sexually transmitted infections (STIs).

Methods

We conducted a multicenter quality improvement project at 3 hospitals in Missouri. PWID with SIRI who received an infectious diseases consultation were prospectively identified and placed into an electronic database as part of a Centers for Disease Control and Prevention–funded quality improvement project. Baseline data were collected from 8/1/2019 to 1/30/2020. During the intervention period (2/1/2020–2/28/2021), infectious diseases physicians caring for patients received 2 interventions: (1) email reminders of best practice screening for HIV, viral hepatitis, and STIs; (2) access to a customized EPIC SmartPhrase that included checkboxes of orders to include in assessment and plan of consultation notes. STI screening rates were compared before and after the intervention. We then calculated odds ratios to evaluate for risk factors for STIs in the cohort.

Results

Three hundred ninety-four unique patients were included in the cohort. Initial screening rates were highest for hepatitis C (88%), followed by HIV (86%). The bundled intervention improved screening rates for all conditions and substantially improved screening rates for gonorrhea, chlamydia, and syphilis (30% vs 51%, 30% vs 51%, and 39 vs 60%, respectively; P < .001). Of patients who underwent screening, 16.9% were positive for at least 1 STI. In general, demographics were not strongly associated with STIs.

Conclusions

PWID admitted for SIRI frequently have unrecognized STIs. Our bundled intervention improved STI screening rates, but additional interventions are needed to optimize screening.

Preferences for Expedited Partner Therapy Among Adolescents in an Urban Pediatric Emergency Department: A Mixed-Methods Study

OBJECTIVES

Expedited partner therapy (EPT) refers to treating sexual partners of patients with sexually transmitted infections by providing prescriptions or medications to give to their partners. Expedited partner therapy is not routinely prescribed in the emergency department (ED). Our objective was to explore adolescent preferences for EPT use in the ED.

METHODS

We conducted a mixed-methods study using surveys and semistructured interviews in one urban ED. Sexually active patients aged 15 to 19 years completed an anonymous survey eliciting (1) sexual history and risky sexual behaviors, (2) preferences for partner notification when hypothetically testing positive for an STI, and (3) preferences for EPT. A subsample of survey respondents participated in the interviews, which were conducted until no new perspectives emerged. Investigators analyzed interviews using thematic analysis.

RESULTS

A total of 247 participants completed surveys; the majority were female (183/247, 74%), Hispanic (209/243, 86%), and did not use a condom at last intercourse (129/243, 53%). Two thirds of participants (152/236, 64%) did not prefer EPT for partner notification. Preference for EPT was not associated with sex, age, ethnicity, condom use, a steady sexual partner, or STI history. Qualitative data from both surveys and interviews revealed the following reasons for not preferring EPT: concern for partner safety, importance of determining partner STI status, perceived benefit of clinical interaction, and partner accountability. Reasons for preferring EPT included increased treatment accessibility and convenience.

CONCLUSIONS

The majority of adolescent patients in a pediatric ED did not prefer EPT. Emergency department practitioners should address common concerns regarding EPT to increase EPT adherence if prescribed.

Cost-effectiveness of Sexually Transmitted Infection Screening for Adolescents and Young Adults in the Pediatric Emergency Department

IMPORTANCE

Adolescents and young adults compose almost 50% of all diagnosed sexually transmitted infection (STI) cases annually in the US. Given that these individuals frequently access health care through the emergency department (ED), the ED could be a strategic venue for examining the identification and treatment of STIs.

OBJECTIVE

To examine the cost-effectiveness of screening strategies for Chlamydia trachomatis and Neisseria gonorrhoeae (chlamydia and gonorrhea) in adolescents and young adults who seek acute care at pediatric EDs.

DESIGN, SETTING, AND PARTICIPANTS

This economic evaluation is a component of an ongoing, larger multicenter clinical trial at the Pediatric Emergency Care Applied Research Network. A decision analytic model, created using literature-based estimates for the key parameters, was developed to simulate the events and outcomes associated with 3 strategies for screening and testing chlamydial and gonococcal infections in individuals aged 15 to 21 years who sought acute care at pediatric EDs. Data sources included published (from January 1, 1997, to December 31, 2019) English-language articles indexed in MEDLINE, bibliographies in relevant articles, insurance claims data in the MarketScan database, and reimbursement payments from the Centers for Medicare and Medicaid Services. Because the events and outcomes were simulated, a hypothetical population of 10 000 ED visits by adolescents and young adults was used.

INTERVENTIONS

The 3 screening strategies were (1) no screening, (2) targeted screening, and (3) universally offered screening. Targeted screening involved the completion of a sexual health survey, which yielded an estimated STI risk (at risk, high risk, or low risk).

MAIN OUTCOMES AND MEASURES

Outcome metrics included cost (measured in 2019 US dollars) and the detection and successful treatment of STIs. The incremental cost-effectiveness ratio (ICER) of each strategy was calculated in a base case analysis. The ICER reflects the cost per case detected and successfully treated.

RESULTS

A 3.6% prevalence of chlamydia and gonorrhea was applied to a hypothetical population of 10 000 ED visits by adolescents and young adults. Targeted screening resulted in the detection and successful treatment of 95 of 360 STI cases (26.4%) at a cost of $313 063, and universally offered screening identified and treated 112 of 360 STI cases (31.1%) at a cost of $515 503. The ICER for targeted screening vs no screening was $6444, and the ICER for universally offered screening vs targeted screening was $12 139.

CONCLUSIONS AND RELEVANCE

This economic evaluation found that targeted screening and universally offered screening compared with no screening appeared to be cost-effective strategies for identifying and treating chlamydial and gonococcal infections in adolescents and young adults who used the ED for acute care. Universally offered screening was associated with detecting and successfully treating a higher proportion of STIs in this population.

Pediatric Emergency Provider Sexually Transmitted Infection Screening Practices in Adolescents With Oropharyngeal or Anorectal Chief Complaints

OBJECTIVES

Sexually transmitted infections (STIs) may present with oropharyngeal or anorectal symptoms. Little is known about the evaluation of adolescents with these complaints in the pediatric emergency department (PED). This study aimed to determine the frequency of and factors associated with STI consideration and testing in this population.

METHODS

Retrospective chart review of patients aged 13 to 18 years who presented to an urban PED with oropharyngeal or anorectal chief complaints between June 2014 and May 2015. Sexually transmitted infection consideration was defined as sexual history documentation, documentation of STI in differential diagnosis, and/or diagnostic testing. Multivariate logistic regression models were used to identify factors associated with consideration.

RESULTS

Of 767 visits for oropharyngeal (89.4%), anorectal (10.4%), or both complaints, 153 (19.9%) had STI consideration. Of the 35 visits (4.6%) that included gonorrhea and/or chlamydia testing, 12 (34.3%) included testing at the anatomic site of complaint. Of those 12 tests, 50.0% were the incorrect test. Patients with older age (adjusted odds ratio [aOR] = 1.5, 95% confidence interval [CI] = 1.3-1.7), female sex (aOR = 1.6, 95% CI = 1.03-2.5), or anorectal complaints (aOR = 2.4, 95% CI = 1.3-4.3) were more likely to have STI consideration.

CONCLUSIONS

In an urban PED, only 20% of visits for adolescents with oropharyngeal or anorectal symptoms included STI consideration. Testing was performed in only 5% of cases and often at an inappropriate anatomic site or with the incorrect test. Interventions to increase awareness of appropriate STI consideration and testing for individuals presenting with possible extragenital complaints may help reduce STIs among adolescents.

Performance evaluation and acceptability of point-of-care Trichomonas vaginalis testing in adult female emergency department patients

We evaluated the accuracy and perception of a patient self-administered, tablet-facilitated rapid Trichomonas vaginalis (TV) point-of-care (POC) test in adult female emergency department (ED) patients.ED patients undergoing gynecologic examination were eligible. Each consented participant self-collected a vaginal swab, performed a tablet-facilitated TV rapid test using the OSOM® Trichomonas Rapid Test, and completed pre- and post-test self-surveys. After the self-test, the clinician collected one standard-of-care (SOC) vaginal swab for wet-mount testing and two for research. The research coordinator performed the TV rapid test using the clinician-collected swab, and reported the results to the clinician and patient. If the self- and coordinator-performed results were discordant, a TV nucleic acid amplification test (NAAT) was performed in a clinical laboratory. A survey was later administered to providers to assess their perceptions of the utility of the POC TV test.Of the 136 participants, 134 (98.5%) completed self-testing; two had invalid results. Comparing coordinator-performed TV rapid test adjudicated with NAAT, the sensitivity and specificity of self-administered test was 96.0% and 100%, respectively. The wet mount had a sensitivity of 52.0% and specificity of 100%. TV detection increased from 9.6% with wet mount to 18.4% with the TV rapid test. Most women (82.0%) stated self-testing was "not at all hard" (versus 66.2% before testing, p < 0.001). Clinicians indicated the TV rapid test affected their clinical management in 48.5% of cases, including 82.6% of positive cases and 41.6% of negative cases.ED patients were able to reliably collect, perform, and interpret their own POC TV test using tablet instructions. Both participants and providers reported high levels of acceptability of POC TV testing, which nearly doubled rates of TV detection.

Adolescent Sexual Behavior and Emergency Department Use

OBJECTIVES

The objective of this study was to determine whether adolescents in emergency departments (EDs) who report engaging in high-risk sexual behaviors are less likely to identify a primary care provider (PCP) and more likely to access the ED than their sexually inexperienced peers.

METHODS

This was a secondary analysis of adolescents presenting to a pediatric ED with non-sexually transmitted infection (STI)-related complaints who completed surveys to assess sexual behavior risk and health care access. We measured differences in self-reported PCP identification, preferential use of the ED, and number of ED visits over a 12-month period by sexual experience. Secondary outcomes included clinician documented sexual histories and STI testing.

RESULTS

Of 758 patients meeting inclusion criteria, 341 (44.9%) were sexually experienced, and of those, 129 (37.8%) reported engaging in high-risk behavior. Participants disclosing high-risk behavior were less likely to identify a PCP (adjusted odds ratio, 0.5; 95% confidence interval [CI], 0.3-0.9), more likely to prefer the ED for acute care issues (adjusted odds ratio, 1.6; 95% CI, 1.0-2.6), and had a higher rate of ED visits (adjusted relative risk, 1.2; 95% CI, 1.0-1.3) compared with sexually inexperienced peers. Among patients disclosing high-risk behavior, 10.9% had clinician-documented sexual histories and 2.6% underwent STI testing.

CONCLUSION

Adolescents who reported engaging in high-risk sexual behaviors were less likely to identify a PCP, as well as more likely to prefer ED-based care and make more ED visits. However, ED clinicians infrequently obtained sexual histories and performed STI testing in asymptomatic youth, thereby missing opportunities to screen high-risk adolescents who may lack access to preventive care.

A Qualitative Assessment to Understand the Barriers and Enablers Affecting Contraceptive Use Among Adolescent Male Emergency Department Patients

Early fatherhood is common in the United States (U.S.). The emergency department (ED) plays a disproportionate role in serving patients with unmet reproductive and sexual health needs. With 8 million adolescent males visiting U.S. EDs annually, the ED is a potential site to implement interventions to minimize early fatherhood and unintended teenage pregnancy. Little is known about how adolescent male ED patients perceive and behave in sexual relationships and how they influence contraceptive decision making. The objective of this study was to identify the barriers and enablers affecting contraceptive and condom use among adolescent male ED patients. Semistructured interviews were conducted with males aged 14–19 in one urban ED. Enrollment continued until saturation of key themes. Interviews were recorded, transcribed, and coded based on thematic analysis using NVivo 10. The Social Ecological Model was used to organize and understand themes. Participants (n = 24) were predominantly 18–19 years (63%) and Hispanic (92%). Most (71%) had sex ≤3 months prior but infrequently used a condom at last intercourse (42%). The primary barrier influencing contraceptive use was lack of knowledge of effective contraceptives. Other barriers consisted of perceived gender roles, poor partner communication, and little relationship with a primary provider. Enablers included intention not to get a partner pregnant, school-based sexual health education, normalcy to use condoms, and a trustworthy confidante. The identified barriers and enablers influencing adolescent males’ perspectives toward contraceptives should be addressed if designing future ED-based pregnancy prevention interventions targeting teen males.

Sex Without Contraceptives in a Multicenter Study of Adolescent Emergency Department Patients

OBJECTIVES

In the United States, rates of teenage pregnancy and sexually transmitted infections (STIs) remain exceptionally high, and racial and ethnic disparities persist. Emergency departments (EDs) care for over 19 million adolescents each year, the majority being minority and low socioeconomic status. Single-center studies demonstrate infrequent use of contraceptives among adolescent ED patients and an association between risky sex and behaviors such as alcohol and drug use; however, no multicenter ED data exist. The objectives of this study were to 1) determine the prevalence of sex without contraceptives in a large multicenter adolescent ED study and 2) assess patient demographic and risky behaviors associated with sex without contraceptives.

METHODS

Participants aged 14 to 17 years (n = 3,247) in 16 pediatric EDs across the United States completed an electronic survey. Questions focused on validated measures of risky sex; use of alcohol, tobacco, marijuana, and other drugs; and depression and violence. In this secondary analysis, we constructed univariable and multivariable models to identify demographic and behavioral factors associated with sex without contraceptives (our primary outcome), separately for adolescent males and females.

RESULTS

In the prior year, 17.4% (236/1,356) of males and 15.8% (299/1,891) of females had sex without contraceptives. In the multivariable model, sex without contraceptives for both genders was more likely among teens who were black, with conduct problems and participated in casual sex, binge drinking, or cannabis use. Sex without contraceptives was also more likely among Hispanic and cigarette-smoking males, as well as depressed females.

CONCLUSIONS

Adolescent ED patients across the United States are participating in risky sexual behaviors that increase their likelihood of pregnancy and STI acquisition. These adolescents report a number of problem behaviors, including substance use, which are strongly correlated with unprotected sex. The ED visit may be an opportunity to identify at-risk adolescent patients, address risky behaviors, and intervene to improve adolescent health.

Frequency of Prescription Filling Among Adolescents Prescribed Treatment for Sexually Transmitted Infections in the Emergency Department

This study investigates prescription filling for the treatment of sexually transmitted infections among adolescents in the emergency department setting.

Physician Adherence to Centers for Disease Control and Prevention Guidelines for Sexually Active Adolescents in the Pediatric Emergency Setting

OBJECTIVES

There is limited literature about physicians' adherence to 2010 Centers for Disease Control and Prevention (CDC) Sexually Transmitted Diseases Treatment Guidelines specific to specimen collection testing methods in adolescent females in the emergency setting is limited. The objectives are to (1) determine physician adherence to CDC guidelines for specimen collection/testing for chlamydia and gonorrhea, (2) determine physician characteristics associated with guideline adherence, and (3) describe physicians' knowledge of expedited partner therapy (EPT) laws.

METHODS

This is a cross-sectional, anonymous, Internet-based survey of physician members of the American Academy of Pediatrics Section of Emergency Medicine. Questions addressed practice patterns and knowledge through clinical scenarios of adolescent girls. Descriptive statistics are used to report frequency. Fisher exact and χ analyses are used to compare physician subgroups: gender, years in practice, practice setting, and geographical region.

RESULTS

Overall, 257 physicians responded and 231 were analyzed; 62.4% females; 46.0% in practice for ≤ 7 years; 86.2% in academic medicine. Specimen collection/testing in an asymptomatic patient were consistent with guidelines for 85.6% of respondents, but decreased to 37.4% for a symptomatic patient. Guideline adherence was not different between physician subgroups. Only 30.4% of physicians reported state EPT law knowledge.

CONCLUSIONS

Adherence with the CDC guidelines for chlamydia/gonorrhea specimen collection/testing for adolescents in the emergency setting is inadequate, and EPT knowledge is poor. With increased emergency department use by adolescents, it is critical that physicians know and implement the current recommendations to improve adolescent health outcomes.

Management of Patients with Sexually Transmitted Infections in the Emergency Department

Sexually transmitted infections (STI) are very common infections in the United States. Most patients with STIs are evaluated and treated in primary care settings; however, many also present to the Emergency Department (ED) for initial care. Management of STIs in the ED includes appropriate testing and treatment per CDC Sexually Transmitted Diseases Treatment Guidelines. Although most patients with STIs are asymptomatic or may only exhibit mild symptoms, serious complications from untreated infection are possible. Pregnant women with STIs are particularly vulnerable to serious complications; therefore, empiric ED treatment combined with close follow-up care and referral to obstetrics are paramount.

Sensitivity and Specificity of Empiric Treatment for Sexually Transmitted Infections in a Pediatric Emergency Department

OBJECTIVE

To determine test characteristics of provider judgment for empiric antibiotic provision to patients undergoing testing for a sexually transmitted infection.

STUDY DESIGN

We conducted a retrospective cross-sectional electronic health record review of all patients aged 13-19 years who had Neisseria gonorrhoeae (GC) and Chlamydia trachomatis (CT) testing sent from an urban, academic pediatric emergency department in 2012. We abstracted data, including patient demographics, chief complaint, sexually transmitted infection test results, and treatment. We calculated test characteristics comparing clinician judgment for presumptive treatment for a sexually transmitted infection with the reference standard of the actual results of testing for a sexually transmitted infection.

RESULTS

Of 1223 patient visits meeting inclusion criteria, 284 (23.2%) had a positive GC and/or CT test result. Empiric treatment was provided in 615 encounters (50.3%). Provider judgment for presumptive treatment had an overall sensitivity of 67.6% (95% CI, 61.8-73.0) and a specificity of 55% (95% CI, 51.7-58.2) for accurate GC and/or CT detection.

CONCLUSIONS

Many adolescents tested for GC and CT receive empiric treatment at the initial emergency department visit. Provider judgment may lack sufficient sensitivity and specificity for identifying infected patients, resulting in the potential for undertreatment of true disease, overtreatment of uninfected patients, or both.

Screening for asymptomatic chlamydia and gonorrhea in adolescent males in an urban pediatric emergency department

AIM

To determine the prevalence of Chlamydia trachomatis (CT) and Neisseria gonorrhea (GC) in young men seeking care in the emergency department (ED) for non-sexually transmitted infection (STI) related symptoms.

METHODS

This was a prospective, cross-sectional study in an urban ED. The main outcome was the rate of positive CT and GC on urine nucleic acid amplification testing in males aged 16-21 presenting with non-STI related complaints.

RESULTS

Two hundred and eighty-four patients were enrolled, 271 were included in the final data analysis [age range 16-21, median: 18 (quartiles 16-18, 19-21)]. Overall, 17 (6.3%, 95%CI: 4%-10%) tested positive for CT and 0% (95%CI: 0%-2%) were found to have GC. The proportion of sexually active subjects was 71% (95%CI: 65%-76%) and 2% (95%CI: 0.6%-4%) reported sex with men. Previous STI testing was reported in 46% (95%CI: 43%-54%) and 13% (95%CI: 8%-20%) of those patients previously tested had a history of STI. Of the patients who tested positive for CT in the ED, 88% (95%CI: 64%-98%) were successfully followed up.

CONCLUSION

The prevalence of CT infection found by screening was 6.3%. Screening and follow-up from the ED was successful. The findings justify routine STI screening in male adolescents presenting to the ED with non-STI related complaints.

A Computerized Sexual Health Survey Improves Testing for Sexually Transmitted Infection in a Pediatric Emergency Department

OBJECTIVES

To assess whether clinical decision support, using computerized sexually transmitted infection (STI) risk assessments, results in increased STI testing of adolescents at high risk for STI.

STUDY DESIGN

In a 2-arm, randomized, controlled trial conducted at a single, urban, pediatric emergency department, adolescents completed a computerized sexual health survey. For patients assigned to the intervention arm, attending physicians received decision support to guide STI testing based on the sexual health survey-derived STI risk; in the usual care arm, decision support was not provided. We compared STI testing rates between the intervention and usual care groups, adjusting for potential confounding using multivariable logistic regression.

RESULTS

Of the 728 enrolled patients, 635 (87.2%) had evaluable data (323 intervention arm; 312 usual care arm). STI testing frequency was higher in the intervention group compared with the usual care group (52.3% vs 42%; aOR 2 [95% CI 1.1, 3.8]). This effect was even more pronounced among the patients who presented asymptomatic for STI (28.6 vs 8.2%; aOR 4.7 [95% CI 1.4-15.5]).

CONCLUSIONS

Providing sexual health survey-derived decision support to emergency department clinicians led to increased testing rates for STI in adolescents at high risk for infection, particularly in those presenting asymptomatic for infection. Studies to understand potential barriers to decision support adherence should be undertaken to inform larger, multicenter studies that could determine the generalizability of these findings and whether this process leads to increased STI detection.

Screening for Asymptomatic Gonorrhea and Chlamydia in the Pediatric Emergency Department

BACKGROUND

Because adolescents rely heavily on emergency services for health care, a pediatric emergency department (PED) visit may be their only opportunity for sexually transmitted infection (STI) screening. The primary objectives of this study were to determine the proportion of Neisseria gonorrheae (GC) and Chlamydia trachomatis (CT) infections in asymptomatic PED adolescents and patient-perceived barriers to STI screening.

METHODS

A convenience sample of patients aged 14 to 21 years presenting to an urban PED with nongenitourinary complaints was offered screening for GC and CT. Regardless of declining or accepting screening, all were asked to complete a questionnaire designed to identify barriers to screening.

RESULTS

Sixty-eight percent of those approached participated (n = 719). Those who agreed to STI screening were more likely to be nonwhite (61.4% vs. 38.6%, P = 0.001) and publically insured (63.3%) versus privately insured (29.3%) or no insurance (7.58%). Four hundred three (56%) participants provided urine samples, and of those, 40 (9.9%) were positive for an STI. Controlling for other demographics, race was a significant predictor, with the odds of testing positive for nonwhite participants 5.90 times that of white participants. Patients who refused testing were more likely to report not engaging in sexual activity (54.3% vs. 42.4%, P = 0.009) and less likely to perceive that they were at risk for STIs.

CONCLUSIONS

There are high proportions of GC and CT among asymptomatic adolescents visiting an academic urban PED. A universal PED STI screening program may be an important component of STI reduction initiatives, especially among adolescents who do not perceive that they are at risk and may not receive testing elsewhere.

Factors associated with the over-treatment and under-treatment of gonorrhea and chlamydia in adolescents presenting to a public hospital emergency department

OBJECTIVES

The purpose of this study was to measure the prevalence of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) and the rates and factors associated with their over-treatment (OT) and under-treatment (UT).

METHODS

A retrospective chart review was performed of patients aged 13-24 years who were screened for GC/CT in the emergency department (ED) of a public hospital. Descriptive statistics were obtained for all variables, and multivariate log binomial regression was performed to ascertain the factors associated with OT and UT.

RESULTS

Seven hundred and ninety-seven adolescents and young adults were screened for GC/CT. The overall sexually transmitted infection (STI) positivity rate was 21.6%; 136 (21.6%) subjects were over-treated and 74 (43.4%) subjects were under-treated. Patients presenting with STI exposure or genito-urinary symptoms were more likely to be OT. Additionally, females aged 18-19 years or with a prior history of STIs were more likely to be OT. Females (83.6%) were more likely to be UT, while STI exposure, genito-urinary symptoms, and a prior history of STI were protective of UT .

CONCLUSION

Adolescents and young adults screened for STIs have a high prevalence of GC/CT. A significant proportion of these patients end up over-treated and an even higher proportion are under-treated.

Development of a Sexual Health Screening Tool for Adolescent Emergency Department Patients

OBJECTIVE

The objective was to develop a content-valid audio computer-assisted self-interview (ACASI) sexual health survey (SHS) that is understandable and acceptable to adolescents and can be feasibly implemented in a pediatric emergency department (ED) for sexually transmitted infection (STI) risk assessment.

METHODS

Multistep iterative qualitative study utilizing a Delphi panel of key informants for survey development and content validity, cognitive interviews with end-users to evaluate understanding, and pilot testing with end-users to evaluate acceptability and feasibility.

RESULTS

We developed a 20-item questionnaire through an iterative modified Delphi process with experts in adolescent and pediatric emergency medicine. All items were assessed as understandable by >90% of adolescents during the cognitive interviews. All respondents found the SHS easy to use. A total of 76.5% preferred answering questions related to sexual health through the SHS compared to face-to-face interviews. Mean (±SD) length of survey completion was 17.5 (±6.7) minutes and 88.6% of participants found survey length to be "just right." With respect to feasibility testing, there was no statistically significant difference in median ED LOS between those who piloted the SHS and those who did not (230.0 minutes vs. 219.0 minutes; p = 0.7).

CONCLUSIONS

We developed a content-valid ACASI for the identification of adolescents at risk for STIs that was understandable, acceptable, and easy to use by adolescent patients and feasible for implementation in the pediatric ED. Future planned steps include the evaluation of the SHS in providing clinical decision support for targeted STI screening in the ED.

Diagnostic accuracy of self-reported symptomatic assessment versus per speculum/per vaginal examination for the diagnosis of vaginal/cervical discharge and lower abdominal pain syndromes among female sex workers

BACKGROUND

National AIDS Control Organization guidelines on enhanced syndromic case management of sexually transmitted infections (STIs) and reproductive tract infections (RTIs) require per speculum (P/S) and per vaginal (P/V) examinations for diagnosis of STIs. However, it is not known if the addition of P/S and P/V examinations to self-reported symptomatic assessment adds any value for the diagnosis of STI/RTI.

OBJECTIVE

To assess the diagnostic accuracy of P/S and P/V examinations compared with self-reported symptomatic assessment in a cohort of female sex workers (FSWs).

METHODS

We performed a cross-sectional study from August 2009 to June 2010, among 519 FSWs in Surat city, Gujarat, India. Symptomatic assessment for the presence or absence of vaginal/cervical discharge (VCD) or lower abdominal pain (LAP) was done using a self-administered questionnaire. After completion of the questionnaire, all participants underwent P/S and P/V examinations. Summary diagnostic accuracy measures were calculated.

RESULTS

Five hundred and nineteen FSWs between the ages of 18-49 years participated in the study. The median age of participants was 31 years. The prevalence of VCD and LAP syndromes based on vaginal discharge, LAP, or both was 56%, 5,-10%, respectively. The sensitivity of P/S and P/V examinations depending on symptomatic assessment ranged from 47% to 76%. The specificity ranged from 73% to 93%. The positive predictive value ranged from 25% to 83%, and the negative predictive value ranged from 56% to 98%.

CONCLUSION

Symptomatic assessment alone is not adequate for the diagnosis of VCD and LAP syndromes and can lead to a significant number of missed cases (36%). A P/S and P/V examinations is critical for assessment of VCD and LAP syndromes and subsequent treatment.

Universal Screening for Sexually Transmitted Infections among Asymptomatic Adolescents in an Urban Emergency Department: High Acceptance but Low Prevalence of Infection

OBJECTIVES

To evaluate acceptance of sexually transmitted infection (STI) screening and measure STI prevalence in an asymptomatic adolescent emergency department (ED) population.

STUDY DESIGN

This was a prospectively enrolled cross-sectional study of 14- to 21-year-old patients who sought care at an urban pediatric ED with non-STI related complaints. Participants completed a computer-assisted questionnaire to collect demographic and behavioral data and were asked to provide a urine sample to screen for Chlamydia trachomatis and Neisseria gonorrhoeae infection. We calculated STI screening acceptance and STI prevalence. We used logistic regression to identify factors associated with screening acceptance and presence of infection.

RESULTS

Of 553 enrolled patients, 326 (59.0%) agreed to be screened for STIs. STI screening acceptability was associated with having public health insurance (aOR 1.7; 1.1, 2.5) and being sexually active (sexually active but denying high risk activity [aOR 1.7; 1.1, 2.5]; sexually active and reporting high risk activity [aOR 2.6; 1.5, 4.6]). Sixteen patients (4.9%; 95% CI 2.6, 7.3) had an asymptomatic STI. High-risk sexual behavior (aOR 7.2; 1.4, 37.7) and preferential use of the ED rather than primary care for acute medical needs (aOR 4.0; 1.3, 12.3) were associated with STI.

CONCLUSIONS

STI screening is acceptable to adolescents in the ED, especially among those who declare sexual experience. Overall, there was a low prevalence of asymptomatic STI. Risk of STI was higher among youth engaging in high-risk sexual behavior and those relying on the ED for acute health care access. Targeted screening interventions may be more efficient than universal screening for STI detection in the ED.

Prevalence of 3 sexually transmitted infections in a pediatric emergency department

OBJECTIVE

This study aimed to determine the prevalence of Chlamydia trachomatis, Neisseria gonorrheae, and Trichomonas vaginalis and to describe factors associated with sexually transmitted infection (STI) in a pediatric emergency department (ED).

METHODS

Adolescents aged 14 to 19 years presenting to a Midwestern pediatric ED were asked to provide urine for STI testing and complete a survey about previous sexual activity (PSA), high-risk behaviors, demographics, and visit reason (reproductive: genitourinary complaints, abdominal pain, or a female with vomiting). Comparisons between subgroups were analyzed using Χ test.

RESULTS

Among 200 subjects (64% of approached), mean age was 15.6 years; 63% were female. Eleven subjects (6%; 95% confidence interval, 2.3-8.7) tested positive for 1 or more STIs: 10 for C. trachomatis (one denied PSA), 3 for T. vaginalis (all coinfected with C. trachomatis), and 1 for N. gonorrheae. Half reported PSA; of these, 71% reported 1 or more high-risk behaviors, most commonly first sex before the age of 15 years (51%) and no condom at last sex (42%). Among those with PSA and nonreproductive visit (n = 73), 11.0% had 1 or more STIs (95% confidence interval, 3.4-18.1). Two factors were associated with greater likelihood of positive STI test result, namely, reporting PSA versus no PSA (10% vs 1%, P = 0.005) and last sex within 1 month or less versus more than 1 month (20% vs 0%, P = 0.001). In this sample, none of the following characteristics were associated with STI: insurance, race, high-risk behaviors, age, or ED visit reason.

CONCLUSIONS

Approximately 1 in 10 sexually active adolescent ED patients without reproductive complaints had 1 or more STIs. This suggests the need for strategies to increase STI testing for this population.

Improving sexually transmitted infection results notification via mobile phone technology

PURPOSE

To improve adolescent notification of positive sexually transmitted infection (STI) tests using mobile phone technology and STI information cards.

METHODS

A randomized intervention among 14- to 21-year olds in a pediatric emergency department (PED). A 2 × 3 factorial design with replication was used to evaluate the effectiveness of six combinations of two factors on the proportion of STI-positive adolescents notified within 7 days of testing. Independent factors included method of notification (call, text message, or call + text message) and provision of an STI information card with or without a phone number to obtain results. Covariates for logistic regression included age, empiric STI treatment, days until first attempted notification, and documentation of confidential phone number.

RESULTS

Approximately half of the 383 females and 201 males enrolled were ≥18 years of age. Texting only or type of card was not significantly associated with patient notification rates, and there was no significant interaction between card and notification method. For females, successful notification was significantly greater for call + text message (odds ratio, 3.2; 95% confidence interval, 1.4-6.9), and documenting a confidential phone number was independently associated with successful notification (odds ratio, 3.6; 95% confidence interval, 1.7-7.5). We found no significant predictors of successful notification for males. Of patients with a documented confidential phone number who received a call + text message, 94% of females and 83% of males were successfully notified.

CONCLUSIONS

Obtaining a confidential phone number and using call + text message improved STI notification rates among female but not male adolescents in a pediatric emergency department.

Sexual history taking in the emergency department - more specificity required

BACKGROUND

Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) are the most reported diseases in the United States, and emergency departments (ED) serve a population presenting with increased infection risk. However, identifying patients for whom sexually transmitted infection (STI) screening is appropriate requires accurate sexual history reporting.

STUDY OBJECTIVES

To examine the consistency with which ED patients answer general and specific sexual activity questions, and how responses relate to perceived STI risk.

METHODS

Urban ED patients aged 15-34 years completed a sexual history survey containing sexual activity and perceived infection risk questions and provided urine and pharyngeal specimens for CT/GC analysis.

RESULTS

Participants included 192 males and 301 females with a mean age of 25.2 years and were 65.7% white and 33.3% black. Thirty-eight (7.7%) were infected with CT or GC. In patients denying sexual activity in the past year (general question), 40.7% of such males and 45.0% of females also reported some form of specific sexual activity (activity misclassification). Among self-identified heterosexuals, 7.2% males and 7.5% females reported some form of homosexual activity (orientation misclassification; OM). OM individuals were more likely to perceive themselves at risk of infection both orally (odds ratio 2.92, confidence interval 1.12-7.63) and genitally (odds ratio 3.36, confidence interval 1.55-7.30).

CONCLUSIONS

Given that reported sexual activity and age are the only criteria for routine female screening, and that homosexual activity is one of the few screening criteria for males, our results show that a substantial proportion of ED patients eligible for screening may not be identified by reliance upon general sexual history questions.

Adolescent women with sexually transmitted infections: who gets lost to follow-up?

BACKGROUND

Adolescent patients comprise the highest rate of Neisseria gonorrhoeae (GC) and Chlamydia trachomatis (CT) in the United States. These patients often initially present to the emergency department (ED) with vague symptoms.

OBJECTIVES

1) Quantify the frequency of underrecognized GC and CT cervical infections in adolescent women tested in the ED; 2) describe and compare the characteristics of those treated and not treated during the initial visit; and 3) quantify the delay interval until treatment was provided.

METHODS

This was a retrospective, cohort analysis of consecutive females (ages 13-19 years) seen at four academic medical centers over a 36-month period with positive results for GC/CT. Our key outcome measures were the proportion of adolescent females being untreated in the ED, the time to subsequent treatment, and the proportion lost to follow-up.

RESULTS

During the study period, 382 female adolescents had positive polymerase chain reaction studies for GC or CT or both; 266 (70%) were not treated in the ED. Untreated patients were significantly more likely to have a discharge diagnosis of urinary tract infection (23% vs. 11%, p < 0.008), new pregnancy (29% vs. 8%, p < 0.001), and vaginitis (24.8% vs. 5%, p < 0.001). Subsequently, only 11.7% (31/266) of the untreated patients fit the Centers for Disease Control and Prevention guidelines for empiric treatment of pelvic inflammatory disease. After telephone, mail, and public health follow-up, treatment could be documented for only 59% of the patients.

CONCLUSION

The majority of adolescent women found to have GC or CT or both in the ED were not treated at presentation.
