Emergency department management of sexually transmitted infections in US adolescents

Effect of the COVID-19 Pandemic on Chlamydial Infection Treatment in Women Discharged From an Urban Safety-Net Emergency Unit

BACKGROUND

Chlamydia is the most frequently reported sexually transmitted infection. COVID-19 exacerbated the challenges in treating and preventing new Chlamydia trachomatis (CT) infections. This study examined the impact of COVID-19 on treating CT-positive patients discharged from a safety-net women's emergency unit.

METHODS

This was a preretrospective and postretrospective cohort study. Chlamydia trachomatis -positive female patients seen in the women's emergency unit were evaluated. Patients discharged in 2019, the "pre-COVID-19" group, and those discharged in 2020, the "COVID-19" group, were compared. The primary outcome was CT treatment within 30 days, and secondary outcomes included prescription dispensation, repeat tests taken, and expedited partner treatment. A subgroup of patients discharged before treatment who entered a nurse-led follow-up program was also evaluated.

RESULTS

Of the 1357 cases included, there were no differences in successful 30-day treatment (709 of 789 [89.9%] vs. 568 of 511 [89.9%], P = 0.969) or repeat positive CT test (74 of 333 [22.2%] vs. 46 of 211 [21.8%]), P = 0.36) between pre-COVID-19 and COVID-19. However, the patients who picked up their prescription (196 of 249 [78.7%] vs. 180 of 206 [87.4%], P = 0.021) and those who were prescribed expedited partner therapy (156 of 674 [23.1%] vs. 292 of 460 [63.5%], P < 0.001) increased. Findings in the subgroup of patients who entered the follow-up program were consistent with those in the full cohort.

CONCLUSIONS

The COVID-19 pandemic did not change treatment patterns of CT-positive patients in this safety-net women's emergency unit. However, patients were more likely to pick up their medications during COVID-19. Despite the perseverance of these programs through the pandemic, most patients are discharged before positive results, and a fair amount remain untreated.

Rates of Appropriate Treatment and Follow-Up Testing After a Gonorrhea and/or Chlamydia Infection in an Urban Network of Federally Qualified Health Center Systems

BACKGROUND

Reinfection and partner transmission are common with Neisseria gonorrhoeae (GC) and Chlamydia trachomatis (CT). We assessed treatment and follow-up laboratory testing for GC and CT and evaluated associations with patient- and system-level factors.

METHODS

The analysis included positive GC and/or CT nucleic acid amplification test results from patients aged 14 to 24 years at a federally qualified health center system site in Denver, CO, from January 2018 to December 2019. Outcomes assessed include treatment within 14 days, HIV/syphilis testing within 6 months, and repeat GC and CT testing within 2 to 6 months. Bivariate and multivariable regression modeling assessed associated factors.

RESULTS

Among 27,168 GC/CT nucleic acid amplification tests performed, 1.8% (484) were positive for GC and 7.8% (2125) were positive for CT. Within the assessed time frames, 87% (2275) of patients were treated, 54.1% (1411) had HIV testing, 50.1% (1306) had syphilis testing, and 39.9% (1040) had GC and CT retesting. Older patients were more likely to receive treatment (adjusted odds ratio 1.13; 95% confidence interval, 1.00-1.27; P = 0.05) than younger patients, whereas males were less likely to receive GC and CT retesting (adjusted odds ratio, 0.19; 95% confidence interval, 0.11-0.33; P < 0.001) than females. Patients treated on the day of testing were less likely to receive follow-up laboratory tests than those treated 2 to 14 days after.

CONCLUSIONS

Although most patients received antibiotic treatment, only about half received HIV/syphilis testing and less than half received GC and CT retesting. It is critical to find innovative strategies to improve treatment and follow-up management of these infections to decrease complications, reduce transmission, and combat the rising rates of sexually transmitted infections.

A Retrospective Study of Clinical Encounters for Pelvic Inflammatory Disease: Missed Opportunities to Screen for Syphilis and HIV?

OBJECTIVE

Missed screening opportunities may contribute to the rising rates of sexually transmitted and blood borne infections (STBBIs) in Manitoba. This study sought to determine the proportion of women who are screened for syphilis and human immunodeficiency virus (HIV) when admitted with pelvic inflammatory disease (PID).

METHODS

We performed a retrospective analysis of all inpatient admissions for PID over 3 discrete years (fiscal years 2007, 2012, 2017) at a single tertiary care centre. Data extracted from medical records included STBBI screening performed, clinical signs at presentation, and history of PID or STBBI. To improve the accuracy of our estimates, we complemented the records data with population data from Manitoba. We evaluated predictive factors influencing any or concurrent STBBI screening using bivariate analysis for significance (P < 0.05).

RESULTS

One hundred and five admissions met inclusion criteria. Syphilis and HIV screening was ordered concurrently with chlamydia and gonorrhoea screening in 6 (6%) of encounters and was ordered at any point during admission for PID in 28 (27%). A history of substance abuse (odds ratio [OR] 4.94 [95% CI 1.62-15.05] for syphilis screening and OR 6.94 [95% CI 2.38-20.23] for HIV screening) and a positive gonorrhea result while admitted (OR 3.40 [95% CI 1.06-10.88] for syphilis screening) were strongly associated with receiving any screening. Reporting multiple sexual partners was also strongly associated with receiving any STBBI screening while admitted (OR 19.44 [95% CI 2.01-187.92] and OR 15.00 [95% CI 1.58-142.70] for syphilis and HIV screening, respectively).

CONCLUSION

A minority of patients were screened for syphilis and HIV while admitted for PID. This study highlights a missed opportunity to screen for STBBI among sexually active women.

Adolescents' Awareness of and Attitudes Toward Expedited Partner Therapy Provided in the Emergency Department

BACKGROUND

Adolescents and young adults account for half of the 20 million new cases of sexually transmitted infections each year. Expedited partner therapy (EPT) has been shown to decrease reinfection rates and is recommended by the Centers for Disease Control and Prevention. We aimed to (1) assess adolescents' awareness of EPT, (2) assess their likelihood of giving EPT received in the pediatric emergency department (PED) to their partner(s), and (3) identify factors associated with increased likelihood of giving EPT to their partner(s).

METHODS

Adolescents and young adults aged 14 to 22 years seeking care in 2 PEDs participated in a survey. Main outcomes were EPT awareness and likelihood of giving EPT to his/her partner(s). Patients were dichotomized into likely and not likely to provide partner(s) with EPT based on answers to a 5-point Likert scale question. χ and t tests were used to analyze the data.

RESULTS

Three hundred ninety-three participants were included. Only 11% (n = 42) were aware of EPT; however, 80% (n = 316) reported to be likely to give EPT received in the PED to his/her partner(s). Study site, being sexually active, and engaging in high-risk sexual behaviors were associated with an increased likelihood of giving EPT to their partner(s) (P < 0.05).

CONCLUSIONS

Many adolescents are not aware of EPT; however, most were theoretically likely to give EPT received in the PED to his/her partner(s). With increasing rates of sexually transmitted infections and high utilization of the PED for adolescent reproductive health services, efforts to incorporate the use of EPT in PED workflows would be beneficial.

Effectiveness of a Universally Offered Chlamydia and Gonorrhea Screening Intervention in the Pediatric Emergency Department

PURPOSE

Adolescents represent more than half of the newly diagnosed sexually transmitted infections in the U.S. annually. Emergency departments (EDs) may serve as an effective, nontraditional setting to screen for chlamydia/gonorrhea (CT/GC). The objective was to evaluate the effectiveness of a universally offered CT/GC screening program in two pediatric ED settings.

METHODS

This was a prospective, delayed start pragmatic study conducted over 18 months in two EDs within the same academic institution among ED adolescents aged 14-21 years with any chief complaint. Using a tablet device, adolescents were confidentially informed of CT/GC screening recommendations and were offered screening. If patients agreed to CT/GC testing, a clinical decision support tool was triggered to inform the provider and order testing. The main and key secondary outcomes were the proportion of CT/GC testing and positive CT/GC test results in each respective ED.

RESULTS

Both EDs experienced modest but statistically significant increases in CT/GC testing post- versus pre-intervention (main: 11.5% vs. 7.9%; confidence interval [CI]: 2.9-4.2; p < .0001 and satellite: 3.8% vs. 2.6%; 95% CI: .7-1.7; p < .0001). Among those tested, the positivity rate at the main ED did not significantly change post- versus pre-intervention (24.1% vs. 23.2%; 95% CI: -1.9 to 3.8; p = .71) but significantly decreased at the satellite ED (7.6% vs. 14.8%; 95% CI: -12.2 to -2.2; p = .01).

CONCLUSIONS

A universally offered screening intervention increased the proportion of adolescents who were tested at both EDs and the detection rates for CT/GC at the main ED, but patient acceptance of screening was low.

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.

Factors Affecting Treatment with Life-Saving Interventions, Computed Tomography Scans and Specialist Consultations

Background: Emergency treatments determined by emergency physicians may affect mortality and patient satisfaction. This paper attempts to examine the impact of patient characteristics, health status, the accredited level of hospitals, and triaged levels on the following emergency treatments: immediate life-saving interventions (LSIs), computed tomography (CT) scans, and specialist consultations (SCs). Methods: A multivariate logistic regression model was employed to analyze the impact of patient characteristics, including sex, age, income and the urbanization degree of the patient's residence; patient health status, including records of hospitalization and the number of instances of ambulatory care in the previous year; the Charlson Comorbidity Index (CCI) score; the accredited level of hospitals; and the triaged level of emergency treatments. Results: All the patient characteristics were found to impact receiving LSI, CT and SC, except for income. Furthermore, a better health status was associated with a decreased probability of receiving LSI, CT and SC, but the number of instances of ambulatory care was not found to have a significant impact on receiving CT or SC. This study also found no evidence to support impact of CCI on SC. Hospitals with higher accredited levels were associated with a greater chance of patients receiving emergency treatments of LSI, CT and SC. A higher assigned severity (lower triaged level) led to an increased probability of receiving CT and SC. In terms of LSI, patients assigned to level 4 were found to have a lower chance of treatment than those assigned to level 5. Conclusions: This study found that several patient characteristics, patient health status, the accredited level of medical institutions and the triaged level, were associated with a higher likelihood of receiving emergency treatments. This study suggests that the inequality of medical resources among medical institutions with different accredited levels may yield a crowding-out effect.

Implementation of Targeted Point of Care HIV Testing in a Pediatric Emergency Department

HIV infection rates are increasing among adolescents. Despite guidelines recommending annual HIV screening among sexually active adolescents, 3.6% of adolescents tested for other sexually transmitted infections (STI) in a pediatric emergency department (PED) were screened for HIV. The aim was to increase HIV screening to 90%.

Clinical knowledge of human immunodeficiency virus and sexually transmitted infections among emergency medicine providers

Introduction

This study examines the association of the domains of knowledge for HIV and sexually transmitted infections (STIs) among emergency medicine providers (EP).

Methods

From February 2018 to March 2018, 75 EP (physicians, residents, and advanced practice providers) completed an anonymous, self-administered survey. The primary outcome of strength of correlation between HIV and STI sections of the survey was analyzed using Spearman’s rank-order coefficient.

Results

Respondents were physicians (54.6%), male (56%), Caucasian (83.7%), with eight years in practice (IQR: 2,16). Spearman’s correlation of HIV and STIs showed a weak positive correlation ( r = 0.35, p = 0.002). There was no association between HIV scores and provider type ( p = 0.67) or provider gender ( p = 0.89) as well as no association between STI scores and provider type ( p = 0.10) or provider gender ( p = 0.79).

Conclusion

The results of our study reveal that when presented with a patient at high risk for undiagnosed HIV or with undiagnosed symptomatic HIV infection, most providers either do not test or do not have HIV in the differential diagnosis. Similarly, knowledge of STIs is only weakly correlated with knowledge of HIV risk factors and symptomatic HIV infection. Further research and screening efforts may benefit by focusing on HIV education among emergency medicine providers.

Pelvic Inflammatory Disease in a Pediatric Emergency Department: Epidemiology and Treatment

OBJECTIVES

Most adolescent cases of pelvic inflammatory disease (PID) are diagnosed in the emergency department (ED). An important step to prevent PID-related morbidity among this high-risk population is to quantify prevalence and microbial patterns and identify testing and treatment gaps.

METHODS

We performed a retrospective, cross-sectional study of all visits by adolescents to an urban children's ED with an International Classification of Diseases, Ninth Revision, diagnosis of PID in 2012. We used standard descriptive statistics to quantify PID diagnoses, sexually transmitted infections (STI) testing, and treatment.

RESULTS

Pelvic inflammatory disease was diagnosed in more than 9% of women with a chief complaint of abdominal/pelvic pain. Most diagnosed cases underwent some STI testing, and 40% tested positive. Seventy percent of cases received antibiotics recommended by the Centers for Disease Control and Prevention.

CONCLUSIONS

There is a high prevalence of PID among adolescents in the pediatric ED. Rates of STI testing and appropriate treatment reveal gaps in diagnosis and management, representing a lost opportunity for identification and treatment of PID/STIs among high-risk adolescents.

The influence of race and sex on gonorrhea and chlamydia treatment in the emergency department

BACKGROUND

Emergency Departments (EDs) are a care source for patients with sexually transmitted diseases (STDs). St. Louis, MO reports among the highest rates of gonorrhea and chlamydia infection. We examined STD treatment in a high-volume urban ED, in St. Louis MO, to identify factors that may influence treatment.

METHODS

A retrospective chart review and analysis was conducted on visits to a high volume, academic ED in St. Louis, MO where patients received a gonorrhea/chlamydia nucleic acid amplification test (NAAT) with a valid matching test result over two years. Using multiple logistic regression, we examined available predictors for under and overtreatment.

RESULTS

NAATs were performed on 3.3% of all ED patients during the study period. Overall prevalence was 6.9% for gonorrhea (95% CI: 6.2, 7.7) and 11.6% for chlamydia (95% CI: 10.6, 12.5). Race was not a statistically significant predictor for undertreatment but Black patients were significantly more likely to be overtreated compared to White patients. (OR 1.83, 95% CI: 1.5, 2.2). Females were more likely to be undertreated when positive for infection compared to males (OR 7.34, 95% CI: 4.8, 11.2) and less likely to be overtreated when negative for infection (OR 0.27, 95% CI: 0.2, 0.3).

CONCLUSION

The burden of STDs in a high-volume academic ED was significant and treatment varied across groups. Attention should be paid to particular groups, specifically women and patients reporting Black as their race, to ensure appropriate treatment is administered. Patients would benefit from targeted STD management protocols and training in the ED.

Increasing Trichomonas vaginalis testing for high-risk adolescents a pediatric emergency department

Background

Trichomonas is a common sexually transmitted infection (STI) among adolescents, causing vaginal discharge, pelvic pain, and dysuria. Affected individuals have increased susceptibility to other STIs and may have pregnancy complications. A quality improvement project was developed to increase trichomonas testing among high-risk adolescent patients from 40% in July 2014 to 100% by December 31, 2014, and sustain over 6 months.

Methods

An interdisciplinary team (providers and support staff) was assembled to address this objective. We collected 6 months of baseline data. Deploying the Institute for Healthcare Improvement Model for Improvement, we formulated an aim statement and identified key drivers. We used cause analysis to identify interventions for each problem area. Multiple Plan-Do-Study-Act cycles were undertaken, and results were monitored using control charts. Interventions included increasing awareness and education for clinical staff; changing computer order entry for the test; using order sets for STI; and adding a Licensed Professional Initiated Protocol to nurse ordering practice. These interventions were all done in conjunction with feedback to providers for individual missed cases.

Results

Over 18 months, the trichomonas testing rate rose with each intervention: from 25% (January 2014) to 98% (December 2014), which we have sustained through June 2015.

Implications and Contributions

This article demonstrates the successful use of quality improvement methodology to increase rates of Trichomonas vaginalis testing among at-risk adolescent patients. Increased testing results in increased detection and improved treatment and sexual health for our patients.

Conclusion

Improving the trichomonas testing process in the pediatric emergency department results in higher screening rates among high-risk adolescent patients.

HIV and Syphilis Screening Among Adolescents Diagnosed With Pelvic Inflammatory Disease

BACKGROUND AND OBJECTIVES

Women with pelvic inflammatory disease (PID) are at an increased risk for syphilis and HIV, but screening rates among adolescents have been understudied. Our objective is to measure the frequency of HIV and syphilis screening among adolescents who are diagnosed with PID and identify patient- and hospital-level characteristics associated with screening.

METHODS

We performed a retrospective cohort study using the Pediatric Health Information System from 2010 to 2015. We included visits to the emergency department by female adolescents who were diagnosed with PID and determined the frequency of HIV and syphilis screening. We performed separate multivariable logistic regression analyses to identify factors associated with screening.

RESULTS

Of the 10 698 patients who were diagnosed with PID, 22.0% (95% confidence interval [CI] 21.2%-22.8%) underwent HIV screening, and 27.7% (95% CI 26.9%-28.6%) underwent syphilis screening. Screening rates varied by hospital (HIV: 2.6%-60.4%; syphilis: 2.9%-62.2%). HIV screening was more likely to occur in younger (adjusted odds ratio [aOR] 1.2; 95% CI 1.0-1.3), non-Hispanic African American (aOR 1.4; 95% CI 1.2-1.7), non-privately insured (publicly insured [aOR 1.3; 95% CI 1.1-1.5], uninsured [aOR 1.6; 95% CI 1.2-2.0]), and admitted patients (aOR 7.0; 95% CI 5.1-9.4) at smaller hospitals (aOR 1.4; 95% CI 1.0-1.8). Syphilis screening was more likely to occur in younger (aOR 1.1; 95% CI 1.0-1.3), non-Hispanic African American (aOR 1.8; 95% CI 1.2-2.8), non-privately insured (publicly insured [aOR 1.4; 95% CI 1.2-1.6], uninsured [aOR 1.6; 95% CI 1.2-1.9]), and admitted patients (aOR 4.6; 95% CI 3.3-6.4).

CONCLUSIONS

We found low rates of HIV and syphilis screening among adolescents who were diagnosed with PID, with wide variability across hospitals.

Sexually Transmitted Infection Review for the Acute Care Pharmacist

PURPOSE

Review selected sexually transmitted infections (STIs) and treatment recommendations for pharmacists and providers practicing in the acute care setting.

SUMMARY

In 2015, the Centers for Disease Control and Prevention (CDC) published an updated guideline on the treatment of STIs with an emphasis on prevention and new diagnostic strategies to combat the growing problem of STIs in the United States. Despite this guidance, the incidence of infection has continued to grow. In October 2016, an in-depth analysis reported that 20 million new infections occur annually in the United States. With this growing burden of disease, it is pertinent that health-care providers optimize their treatment strategies to improve upon the management of STIs. Focusing on identification of asymptomatic- and symptomatic-infected persons, treatment, education, effective follow-up, and counseling for patients and sexual partners, emergency medicine pharmacists and providers can help minimize the negative long-term health consequences of STIs.

CONCLUSION

In the emergency department setting, clinical pharmacists and providers can play a crucial role in preventing and treating STIs and should continue to expand and keep current their knowledge of this topic.

Trends in pelvic inflammatory disease emergency department visits, United States, 2006-2013

BACKGROUND

Pelvic inflammatory disease is a female genital tract disorder with severe reproductive sequelae. Because of the difficulties in diagnosing pelvic inflammatory disease, it is not a reportable condition in many states. Females seeking care in emergency departments are a sentinel population for pelvic inflammatory disease surveillance.

OBJECTIVE

The objective of the study was to determine trends in diagnoses of acute pelvic inflammatory disease in a nationally representative sample of emergency departments.

STUDY DESIGN

All emergency department visits among females aged 15-44 years with an International Classification of Diseases, ninth revision, Clinical Modification diagnosis code indicating pelvic inflammatory disease during 2006-2013 were assessed from the HealthCare Utilization Project Nationwide Emergency Department Sample. Total and annual percentage changes in the proportion of pelvic inflammatory disease emergency department visits were estimated using trend analyses.

RESULTS

While the number of emergency department visits among females aged 15-44 years during 2006-2013 increased (6.5 million to 7.4 million), the percentage of visits due to pelvic inflammatory disease decreased from 0.57% in 2006 to 0.41% in 2013 (total percentage change, -28.4%; annual percent change, -4.3%; 95% confidence interval, -5.7% to -2.9%). The largest decreases were among those aged 15-19 years (total percent change, -40.6%; annual percentage change, -6.6%; 95% confidence interval, -8.6% to -4.4%) and living in the South (total percentage change, -38.0%; annual percentage change, -6.2%; 95% confidence interval, -7.8% to -4.6%). Females aged 15-19 years who lived in the South had a 47.9% decrease in visits due to pelvic inflammatory disease (annual percentage change, -8.4%, 95% confidence interval, -10.4 to -6.5). Patients living in ZIP codes with the lowest median income (<$38,000) had the highest percent of visits with a pelvic inflammatory disease diagnosis; the smallest declines over time were in patients living in ZIP codes with the highest median income (i.e., >$64,000, total percent change, -24.4%; annual percent change, -3.8%; 95% confidence interval, -5.2% to -2.4%). The percentage of emergency department visits due to pelvic inflammatory disease was highest among patients not charged for their visit, self-paying, or those covered by Medicaid, with total percentage changes in these 3 groups of -27.8%, -30.7%, and -35.1%, respectively. Patients with Medicaid coverage had the largest decrease in visits with a diagnosis of pelvic inflammatory disease (total percent change, -35.1%; annual percent change, -5.8%; 95% confidence interval, -7.2% to -4.3%).

CONCLUSION

Nationally representative data indicate the percentage of emergency department visits with a pelvic inflammatory disease diagnosis decreased during 2006-2013 among females aged 15-44 years, primarily driven by decreased diagnoses of pelvic inflammatory disease among females aged 15-19 years and among women living in the southern United States. Despite declines, a large number of females of reproductive age are receiving care for pelvic inflammatory disease in emergency departments. Patients with lower median income and no or public health insurance status, which may decrease access to and use of health care services, consistently had the highest percentage of emergency department visits due to pelvic inflammatory disease. Future research should focus on obtaining a better understanding of factors influencing trends in pelvic inflammatory disease diagnoses and ways to address the challenges surrounding surveillance for this condition.

Gender Differences in CDC Guideline Compliance for STIs in Emergency Departments

Introduction

Sexually transmitted infections (STIs) are a common reason for emergency department (ED) visits. The objective of this study was to determine if there were gender differences in adherence to Centers for Disease Control and Prevention (CDC) STI diagnosis and treatment guidelines, as documented by emergency providers.

Methods

We performed a retrospective chart review to identify patients treated for urethritis, cervicitis, and pelvic inflammatory disease (PID) in the EDs of three hospitals in a Pennsylvania network during a calendar year. Cases were reviewed to assess for compliance with CDC guidelines. We used descriptive statistics to assess the distributions of study variables by patient sex. In the analysis we used Student’s t-tests, chi-square tests, and logistic regression. Statistical significance was set at p ≤ 0.05.

Results

We identified 286 patient records. Of these, we excluded 39 for the following reasons: incorrect disease coding; the patient was admitted and treated as an inpatient for his/her disease; or the patient left the ED after refusing care. Of the 247 participants, 159 (64.4%) were female. Females were significantly younger (26.6 years, SD=8.0) than males (31.2, SD=11.5%), (95% confidence interval [CI] [2.0– 7.0], p=0.0003). All of the males (n=88) in the cohort presented with urethritis; 25.8% of females presented with cervicitis, and 74.2% with PID. Physician compliance for the five CDC criteria ranged from 68.8% for patient history to 93.5% for patient diagnostic testing, including urine pregnancy and gonorrhea/chlamydia cultures. We observed significant differences by patient sex. Fifty-four percent of the charts had symptoms recorded for female patients that were consistent with CDC characteristics for diagnostic criteria compared to over 95% for males, OR=16.9; 95% CI [5.9–48.4], p<0.001. Similar results were observed for patient discharge instructions, with physicians completely documenting delivery of discharge instructions to 51.6% of females compared to 97.7% of complete documentation in males, OR=42.3; 95% CI [10.0–178.6] p<0.001). We observed no significant sex differences in physician documentation for physical exam or for therapeutic antibiotic treatment.

Conclusion

This retrospective study found patient gender differences in how emergency providers complied with documenting with regard to the 2010 CDC guidelines for the diagnosis and treatment of urethritis, cervicitis, and PID. Specifically medical records of men were more likely to have complete documentation of symptoms recorded (95% CI 5.9–48.4) and to have discharge instruction documentation (95% CI 10.0–178.6) than records of women.

Differences in Treatment of Chlamydia trachomatis by Ambulatory Care Setting

Chlamydia trachomatis (CT) is the most commonly reported sexually transmitted infection (STI) in the US and timely, correct treatment can reduce CT transmission and sequelae. Emergency departments (ED) are an important location for diagnosing STIs. This study compared recommended treatment of CT in EDs to treatment in physician offices. Five years of data (2006-2010) were analyzed from the National Ambulatory Medical Care Survey, and the National Hospital Ambulatory Medical Care Surveys (NHAMCS), including the Outpatient survey (NHAMCS-OPD) and Emergency Department survey (NHAMCS-ED). All visits with a CT diagnosis and those with a diagnosis of unspecified venereal disease were selected for analysis. Differences in receipt of recommended treatments were compared between visits to physician offices and emergency departments using Chi square tests and logistic regression models. During the 5 year period, approximately 3.2 million ambulatory care visits had diagnosed CT or an unspecified venereal disease. A greater proportion of visits to EDs received the recommended treatment for CT compared to visits to physician offices (66.1 vs. 44.9 %, p < .01). When controlling for patients' age, sex and race/ethnicity, those presenting to the ED with CT were more likely to receive the recommended antibiotic treatment than patients presenting to a physician's office (OR 2.16; 95 % CI 1.04-4.48). This effect was attenuated when further controlling for patients' expected source of payment. These analyses demonstrate differences in the treatment of CT by ambulatory care setting as well as opportunities for increasing use of recommended treatments for diagnosed cases of this important STI.

Sexually Transmitted Infection History among Adolescents Presenting to the Emergency Department

BACKGROUND

Adolescents and young adults account for about half of the annual diagnoses of sexually transmitted infections (STI) in the United States. Screening and treatment for STIs, as well as prevention, are needed in health-care settings to help offset the costs of untreated STIs.

OBJECTIVE

Our aim was to evaluate the prevalence and correlates of self-reported STI history among adolescents presenting to an emergency department (ED).

METHODS

Over two and a half years, 4389 youth (aged 14-20 years) presenting to the ED completed screening measures for a randomized controlled trial. About half (56%) reported lifetime sexual intercourse and were included in analyses examining sexual risk behaviors (e.g., inconsistent condom use), and relationships of STI history with demographics (sex, age, race, school enrollment), reason for ED presentation (i.e., medical or injury), and substance use.

RESULTS

Among sexually active youth, 10% reported that a medical professional had ever told them they had an STI (212 females, 35 males). Using logistic regression, female sex, older age, non-Caucasian race, not being enrolled in school, medically related ED chief complaint, and inconsistent condom use were associated with increased odds of self-reported STI history.

CONCLUSIONS

One in 10 sexually active youth in the ED reported a prior diagnosed STI. Previous STI was significantly higher among females than males. ED providers inquiring about inconsistent condom use and previous STI among male and female adolescents may be one strategy to focus biological testing resources and improve screening for current STI.

Impact of Post-visit Contact on Emergency Department Utilization for Adolescent Women with a Sexually Transmitted Infection

STUDY OBJECTIVES

To understand Emergency Department (ED) utilization patterns for women who received sexually transmitted infection (STI) testing and explore the impact of post-visit telephone contact on future ED visits.

DESIGN, SETTING, PARTICIPANTS

We performed a secondary analysis on a prospectively collected dataset of ED patients ages 14-21 years at a children's hospital.

INTERVENTIONS AND MAIN OUTCOME MEASURES

The dataset documented initial and return visits, STI results, race, age and post-visit contact success (telephone contact ≤7 days of visit). Logistic regression was performed identifying variables that predicted a return visit to the ED, a return visit with STI testing, and subsequent positive STI results.

RESULTS

Of 922 women with STI testing at their initial ED visit, 216 (23%) were STI positive. One-third (315/922) returned to the ED, 15% (141/922) returned and had STI testing, and 4% (38/922) had a subsequent STI. Of 216 STI-positive women, 59% were successfully contacted. Of those who returned to the ED, age ≥ 18 and Black race were associated with increased STI testing at a subsequent visit. Successful contact reduced the likelihood of STI testing at a subsequent ED visit (OR 0.28, 95% CI 0.01-0.8), and ED empiric antibiotic treatment had no effect on subsequent STI testing.

CONCLUSION

Contacting women with STI results and counseling them regarding safe sex behaviors may reduce the number of ED patients who return with symptoms or a new exposure necessitating STI testing. The high STI prevalence and frequent return rate suggest that ED interventions are needed.

Emergency care for children in the United States

A formal emergency care system for children in the United States began in the 1980s with the establishment of specialized training programs in academic children's hospitals. The ensuing three decades have witnessed the establishment of informal regional networks for clinical care and a federally funded research consortium that allows for multisite research on evidence-based practices. However, pediatric emergency care suffers from problems common to emergency departments (EDs) in general, which include misaligned incentives for care, overcrowding, and wide variation in the quality of care. In pediatric emergency care specifically, there are problems with low-volume EDs that have neither the experience nor the equipment to treat children, poor adherence to clinical guidelines, lack of resources for mental health patients, and a lack of widely accepted performance metrics. We call for policies to address these issues, including providing after-hours care in other settings and restructuring payment and reimbursement policies to better address patients' needs.

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.

Missed opportunities for concurrent HIV-STD testing in an academic emergency department

OBJECTIVES

We evaluated emergency department (ED) provider adherence to guidelines for concurrent HIV-sexually transmitted disease (STD) testing within an expanded HIV testing program and assessed demographic and clinical factors associated with concurrent HIV-STD testing.

METHODS

We examined concurrent HIV-STD testing in a suburban academic ED with a targeted, expanded HIV testing program. Patients aged 18-64 years who were tested for syphilis, gonorrhea, or chlamydia in 2009 were evaluated for concurrent HIV testing. We analyzed demographic and clinical factors associated with concurrent HIV-STD testing using multivariate logistic regression with a robust variance estimator or, where applicable, exact logistic regression.

RESULTS

Only 28.3% of patients tested for syphilis, 3.8% tested for gonorrhea, and 3.8% tested for chlamydia were concurrently tested for HIV during an ED visit. Concurrent HIV-syphilis testing was more likely among younger patients aged 25-34 years (adjusted odds ratio [AOR] = 0.36, 95% confidence interval [CI] 0.78, 2.10) and patients with STD-related chief complaints at triage (AOR=11.47, 95% CI 5.49, 25.06). Concurrent HIV-gonorrhea/chlamydia testing was more likely among men (gonorrhea: AOR=3.98, 95% CI 2.25, 7.02; chlamydia: AOR=3.25, 95% CI 1.80, 5.86) and less likely among patients with STD-related chief complaints at triage (gonorrhea: AOR=0.31, 95% CI 0.13, 0.82; chlamydia: AOR=0.21, 95% CI 0.09, 0.50).

CONCLUSIONS

Concurrent HIV-STD testing in an academic ED remains low. Systematic interventions that remove the decision-making burden of ordering an HIV test from providers may increase HIV testing in this high-risk population of suspected STD patients.

Pelvic inflammatory disease in the adolescent: understanding diagnosis and treatment as a health care provider

BACKGROUND

Pelvic inflammatory disease (PID) is a common clinical syndrome with highest rates in adolescents, but no studies have singularly focused on this population in relationship to established guidelines for diagnosis and treatment. The study objective was to assess knowledge of diagnosis and treatment criteria for PID within an adolescent population and to compare factors associated with adherence to Centers for Disease Control and Prevention guidelines in outpatient settings.

METHODS

Data were collected as part of a retrospective chart review of evaluation, diagnosis, and treatment of sexually transmitted infections in adolescent women in an outpatient setting. Participant charts were eligible for review if they were 12 to 21 years of age and were given an International Classification of Diseases, Ninth Revision/chart diagnosis of PID. Two primary outcome variables were utilized: meeting PID diagnosis guidelines (no/yes) and correct treatment for subject meeting criteria with guidelines (no/yes). The study controlled for race, age, medical venue, and current/past infection with gonorrhea/chlamydia.

RESULTS

Subjects (n = 150) were examined for the primary outcome variables; 78% (117/150) met at least 1 criterion for PID diagnosis. Nearly 75% (111/150) had cervical motion tenderness, 34% (51/150) adnexal tenderness, and 5% (7/150) had uterine tenderness; nearly 11% (16/150) were positive for all 3 criteria. Symptoms associated with PID were compared for subjects meeting diagnosis criteria versus subjects not meeting diagnosis criteria: abdominal pain and vomiting were significantly associated with PID diagnosis at P < 0.05.

CONCLUSIONS

Our findings show that PID diagnosis/treatment often does not follow guidelines in the adolescent population. Pelvic inflammatory disease and cervicitis appear to be confused by providers in the diagnosis process, and educational tools may be necessary to increase the knowledge base of practitioners in regard to PID.

Estimating the direct costs of pelvic inflammatory disease in adolescents: a within-system analysis

We used 2008-2009 physician and hospital charges to estimate the direct cost of medical care per case of pelvic inflammatory disease. The estimated average total charge per episode was $3,025 (SD: $4155). The estimated average charge for patients treated in ambulatory (outpatient clinic and emergency department) settings was $7440 lower than for those treated on inpatient units.

Poor provider adherence to the Centers for Disease Control and Prevention treatment guidelines in US emergency department visits with a diagnosis of pelvic inflammatory disease

BACKGROUND

Pelvic inflammatory disease (PID) is commonly diagnosed in US emergency departments (EDs). We aimed to estimate national rates of provider adherence to the Centers for Disease Control and Prevention (CDC) treatment guidelines for PID among patient visits, with a diagnosis of acute PID in US ED settings.

METHODS

A multiyear cross-sectional analysis was performed on ED visits from females >12 years old, using the National Hospital Ambulatory Medical Care Survey database from 1999 to 2006. The ED diagnoses of acute PID were identified from the database. Specific antibiotics ordered or provided during ED visits diagnosed with PID were identified and compared to contemporary CDC treatment guidelines to determine provider adherence. Analyses were performed using procedures for multiple-stage survey data.

RESULTS

Overall, 1,605,000 discharged ED patient visits with a diagnosis of acute PID were identified. ED provider adherence to CDC treatment guidelines was 30.5% (95% confidence intervals [CI], 24.4%-36.7%). Doxycycline was the most commonly missing medication from the recommended regimens while azithromycin was the most prescribed antibiotic that was not recommended until 2006 CDC guidelines. Additionally, among the visits without being given any CDC-recommended antibiotics, 38.4% were prescribed neither antibiotics nor pain relievers. In multivariate analysis, those without specialty consultation during ED visits and those before the announcement of 2002 guidelines were 4.95 (95% CI, 1.71-14.29) and 1.93 (95% CI, 1.14-3.27) times less likely to receive CDC-recommended antibiotic regimens versus their counterparts.

CONCLUSIONS

Poor provider adherence to the CDC-recommended treatment guidelines for PID has been widespread in US EDs, especially for women who did not receive specialty consultation.

Improving adherence to guidelines for the diagnosis and management of pelvic inflammatory disease: a systematic review

BACKGROUND

Evidence suggests adherence to clinical guidelines for pelvic inflammatory disease (PID) diagnosis and management is suboptimal. We systematically reviewed the literature for studies describing strategies to improve the adherence to PID clinical guidelines.

METHODS

The databases MEDLINE and EMBASE, and reference lists of review articles were searched from January 2000 to April 2012. Only studies with a control group were included.

RESULTS

An interrupted time-series study and two randomised controlled trials (RCTs) were included. The interrupted time-series found that following a multifaceted patient and practitioner intervention (practice protocol, provision of antibiotics on-site, written instructions for patients, and active followup), more patients received the recommended antibiotics and attended for followup. One RCT found a patient video on PID self-care did not improve medication compliance and followup. Another RCT found an abbreviated PID treatment guideline for health-practitioners improved their management of PID in hypothetical case scenarios but not their diagnosis of PID.

CONCLUSION

There is limited research on what strategies can improve practitioner and patient adherence to PID diagnosis and management guidelines. Interventions that make managing PID more convenient, such as summary guidelines and provision of treatment on-site, appear to lead to better adherence but further empirical evidence is necessary.

Identifying adolescent females at high risk of pregnancy in a pediatric emergency department

PURPOSE

Emergency departments (EDs) care for adolescent females with unmet reproductive health care needs. Our objective was, among adolescents presenting to a pediatric ED, to estimate pregnancy risk, describe pregnancy intentions, and identify potentially modifiable factors associated with pregnancy risk.

METHODS

Using a paper-based questionnaire, we surveyed females aged 15-19 years presenting to our ED, assessing health care access, sexual behaviors, pregnancy intentions, and receptivity to interventions. We calculated the pregnancy risk index (PRI), which estimates pregnancy risk in the subsequent 12 months, by assessing recent sexual activity, contraception at last intercourse, and known contraceptive failure rates. Independent sample t tests and analysis of variance were used to identify risk factors associated with increased PRI.

RESULTS

Of 459 females enrolled, 13% were pregnant and 20% reported prior pregnancy. Among 399 nonpregnant females, 238 (60%) had intercourse in the prior 3 months and 73 (31%) used no contraception at last intercourse. Among nonpregnant adolescents, the PRI was 19.5, which equates to 19.5 expected pregnancies per 100 females per year. Factors associated with higher PRI included lacking a primary provider, prior ED visits, wanting a baby now, and reported partner wantedness of pregnancy. Half believed ED doctors should discuss pregnancy prevention, and one-quarter were interested in starting contraception in the ED.

CONCLUSIONS

Nearly one-third of adolescent females in a pediatric ED were either pregnant or could be expected to become pregnant within a year. Screening questions can identify adolescents at high risk of pregnancy in the ED setting. These females should be the target for future pregnancy prevention interventions.

Magnesium use in asthma pharmacotherapy: a Pediatric Emergency Research Canada study

OBJECTIVES

To examine the use of intravenous magnesium in Canadian pediatric emergency departments (EDs) in children requiring hospitalization for acute asthma and association of administration of frequent albuterol/ipratropium and timely corticosteroids with hospitalization.

METHODS

Retrospective medical record review at 6 EDs of otherwise healthy children 2 to 17 years of age with acute asthma. Data were extracted on history, disease severity, and timing of ED stabilization treatments with inhaled albuterol, ipratropium, corticosteroids, and magnesium. Primary outcome was the proportion of hospitalized children given magnesium in the ED. Secondary outcome was the ED use of "intensive therapy" in hospitalized children, defined as 3 albuterol inhalations with ipratropium and corticosteroids within 1 hour of triage.

RESULTS

A total of 19 (12.3%) of 154 hospitalized children received magnesium (95% confidence interval 7.1, 17.5) versus 2 of 962 discharged patients. Children given magnesium were more likely to have been previously admitted to ICU (odds ratio [OR] 11.2), hospitalized within the past year (OR 3.8), received corticosteroids before arrival (OR 4.0), presented with severe exacerbation (OR 6.1), and to have been treated at 1 particular center (OR 14.9). Forty-two (53%) of 90 hospitalized children were not given "intensive therapy." Children receiving "intensive therapy" were more likely to present with severe disease to EDs by using asthma guidelines (ORs 8.9, 3.0). Differences in the frequencies of all stabilization treatments were significant across centers.

CONCLUSIONS

Magnesium is used infrequently in Canadian pediatric EDs in acute asthma requiring hospitalization. Many of these children also do not receive frequent albuterol and ipratropium, or early corticosteroids. Significant variability in the use of these interventions was detected.

Racial disparities in testing for sexually transmitted infections in the emergency department

OBJECTIVES

The objective of this study was to determine predictors of sexually transmitted infection (STI) testing among adolescent females presenting to an urban pediatric emergency department (ED) with symptoms potentially suggestive of an STI.

METHODS

This was a secondary analysis of data collected in a prospective prevalence study of STIs among a consecutive sample of symptomatic females aged 14 to 19 years presenting to a pediatric ED with lower abdominal or genitourinary complaints. The outcome of interest was performance of an STI test. Correlates of interest included patient age, race, insurance status, chief complaint, presence of comorbid conditions, and treating physician sex.

RESULTS

Of the 328 adolescent females who presented to the ED with STI-related complaints and met inclusion criteria, 15.6% did not undergo STI testing. Univariable analysis revealed that black or African American race (odds ratio [OR] = 4.98, 95% confidence interval [CI] = 2.67 to 9.30) and nonprivate insurance (OR = 3.47; 95% CI = 1.83 to 6.58) were significantly associated with the performance of STI testing. In a multivariable model, only black or African American race (OR = 3.94; 95% CI = 1.96 to 7.91) remained significantly associated with the performance of STI testing.

CONCLUSIONS

A substantial number of adolescent females who presented with complaints suggestive of an STI did not undergo STI testing, and a racial disparity in STI testing was noted. The racial disparity in rates of STI testing among symptomatic adolescent girls presenting to the ED warrants further study to confirm validity, to determine if disparity reflects physicians' biases, and to inform strategies for controlling the present epidemic of STIs in adolescents.

Adolescents' use of the emergency department: does source of primary care make a difference?

BACKGROUND

Many of the 18 million emergency department visits by adolescents annually in the United States are for nonurgent problems that might be addressed in a primary care setting.

METHODS

As part of a larger randomized controlled intervention, 1023 adolescents aged 12 to 21 years registering in an urban pediatric emergency department (PED) were tracked over the subsequent 365 days to record all visits to the PED. Adolescents identifying an adolescent medicine service (AMS) as the primary care source were compared with adolescents receiving primary care elsewhere in an integrated urban medical system (non-AMS) to determine how often after the index PED visit they revisited the PED, returned to primary care (PC), visited a subspecialist (SS), or were hospitalized. Mean values and odds ratios of each type of visit were compared between AMS and non-AMS patients using multivariate logistic and ordinary least squares regressions to control for covariates.

RESULTS

AMS patients (n = 124, 12%), compared to non-AMS patients (n = 899, 88%), were more likely female (75% vs 48%, P < .001) and used public insurance (52% vs 40%, P = .017). In unadjusted comparisons, AMS and non-AMS patients did not differ in the probability of any return PED visit (46% vs 37%, P = .052) in the 365 days following the index PED visit but differed in the mean number of return PED visits (1.35 vs 0.93, P = .026). AMS patients were more likely to be hospitalized (15% vs 7%, P = .006) after the index PED visit and also had a greater mean number of hospitalizations (0.41 vs 0.19, P = .048). Multivariate analyses controlling for demographic variables, triage level of initial PED visit, and hospitalizations showed AMS patients returned to primary care after an index PED visit 24.6 days earlier than non-AMS patients (P = .026).

CONCLUSIONS

This study demonstrates attending an AMS for primary care predicted earlier return to the primary care provider after an index PED visit. Elements of adolescent specialty care producing such outcomes are worthy of further study.

Disparities in reproductive health-related visits to the emergency department in Maryland by age and race, 1999-2005

OBJECTIVE

To describe reproductive health-related visits to Maryland emergency departments (EDs) among women aged 15-44 years from 1999 to 2005.

METHODS

We obtained data from the Healthcare Cost and Utilization Project State Emergency Department Database and State Inpatient Database. ICD-9-CM diagnosis codes were used to classify reproductive health-related visits. We calculated the annual rate of reproductive health visits to Maryland EDs from 1999 to 2005 for women aged 15-44 years and tested time trends using linear regression. Admission rates were defined as the percentage of ED visits that resulted in inpatient admission. We calculated age-specific and race-specific rate ratios for diagnoses using Poisson regression and admission rate ratios using Cochran-Mantel-Haenszel statistics.

RESULTS

From 1999 to 2005, the rate of ED visits in Maryland increased 50%, from 28.0 to 42.1 visits per 1000 women. Lower genital tract infections were the most common diagnosis (21.4%). The rates were higher for women aged 15-24 than for women aged 25-44 (rate ratio 1.18, 95% confidence interval [CI] 1.17-1.18) and nearly three times higher for black women than white women (rate ratio 2.94, 95% CI 2.92-2.96). Admission rates were lower for women aged 15-24 than for women aged 25-44 (rate ratio 0.34, 95% CI 0.33-0.35) and were higher among black than white women (rate ratio 1.16, 95% CI 1.14-1.18).

CONCLUSIONS

Disparities by age and race are evident for reproductive health-related ED visits in Maryland, and many of these ED visits are for conditions that are amenable to preventive measures.

Evaluation and management of sexually transmitted infections in adolescent males presenting to a pediatric emergency department: is the chief complaint diagnostic?

OBJECTIVES

The objectives of the study were to (1) describe evaluation and treatment patterns for adolescent males presenting with a concern for sexually transmitted infection (STI) in a pediatric emergency department, (2) assess the rates of STIs in symptomatic males, and (3) determine the utility of urinalysis alone in predicting STIs in adolescent males.

METHODS

A retrospective cohort study was conducted of all patients presenting to our pediatric emergency department from January 1, 2007, to December 31, 2007. Inclusion criteria included males, aged 15 to 21 years, with an STI or urinary chief complaint. Exclusion criteria were referrals from pediatricians, a previous history of urinary tract infection or preexisting urologic condition, or primary complaint of scrotal and/or testicular pain.

RESULTS

A total of 270 patients were identified. Testing included urinalysis with microscopy (UA) (64%), urine culture (53%), Neisseria gonorrhoeae (GC), and Chlamydia trachomatis (CT) (93%), and Trichomonas vaginalis (5%). Sixty-four percent of males tested positive for either GC or CT, or both. Overall, 91% of patients were treated for CT and GC, 18% for T. vaginalis, and 5% for urinary tract infection. The sensitivity and specificity of a positive UA for presence of GC and/or CT were 86% and 82%, respectively, whereas the positive and negative predictive values were 89% and 77%, respectively. There were no positive urine cultures in the cohort.

CONCLUSIONS

Sixty-four percent of patients were diagnosed with either GC or CT. Although UA is helpful in predicting STI, limited use is warranted, given the high prevalence of disease in this selected population. The urine culture does not appear to be a necessary adjunct in the management of these patients.

Emergency department management of sexually transmitted infections

Patients seeking treatment for sexually transmitted infections (STIs) account for a large number of emergency department (ED) visits per year. Despite the large volume of patients, STIs are often missed or treated inappropriately. Due to the high prevalence and incidence of STIs in the United States, it is important that emergency practitioners recognize symptoms consistent with STIs, and treat presumptively. This practice leads to overtreatment of STIs; however, when weighed against the public health risk and complications of untreated disease, empiric treatment is recommended. This article provides an overview of STIs encountered in the ED and recommendations for their treatment.

Emergency department visits by nursing home residents in the United States

OBJECTIVES

To characterize emergency department (ED) use by nursing home residents in the United States.

DESIGN

Analysis of the National Hospital Ambulatory Medical Care Survey.

SETTING

U.S. EDs from 2005 to 2008.

PARTICIPANTS

Individuals visiting U.S. EDs stratified according to nursing home residency.

MEASUREMENTS

All ED visits by nursing home residents were identified. The demographic and clinical characteristics and ED resource utilization, length of stay, and outcomes of nursing home residents and nonresidents were compared.

RESULTS

During 2005 to 2008, nursing home residents accounted for 9,104,735 of 475,077,828 U.S. ED visits (1.9%; 95% confidence interval (CI) = 1.8-2.1%). The annualized number of ED visits by nursing home residents was 2,276,184. Most nursing home residents were older (mean age 76.7, 95% CI = 75.8-77.5), female (63.3%), and non-Hispanic white (74.8%). Nursing home residents were more likely to have been discharged from the hospital in the prior 7 days (adjusted odds ratio (aOR = 1.4, 95% CI = 1.1-1.9), to present with fever (aOR = 1.9, 95% CI = 1.5-2.4) or hypotension (systolic blood pressure ≤90 mmHg, aOR = 1.8, 95% CI = 1.5-2.2), and to receive diagnostic tests (OR = 1.9, 95% CI = 1.6-2.2), imaging (OR = 1.5, 95% CI = 1.3-1.7), or procedures (OR = 1.6, 95% CI = 1.4-1.7) in the ED. Almost half of nursing home residents visiting the ED were admitted to the hospital. Nursing home residents were more likely to be admitted to the hospital (aOR = 1.8, 95% CI = 1.6-2.0) and to die (aOR = 2.3, 95% CI = 1.6-3.3).

CONCLUSION

Nursing home residents account for more than 2.2 million ED visits annually in the United States. Nursing home residents have greater medical acuity and complexity. These observations highlight the national challenges of organizing and delivering ED care to nursing home residents in the United States.

Sexual history documentation in adolescent emergency department patients

OBJECTIVES

To determine the frequency of physician-documented sexual histories in female adolescents who presented to an emergency department (ED) with symptoms suggestive of a sexually transmitted infection (STI). Our secondary objectives were to determine if physician-documented sexual history is associated with increased STI testing and to compare the concordance of physician-elicited sexual histories with patient-documented sexual histories by using confidential questionnaires.

METHODS

We conducted a secondary analysis of a prospective study of female adolescents who presented to a pediatric ED with chief complaints of lower abdominal pain and/or genitourinary complaints. Patient charts were abstracted for the presence or absence of documented sexual histories and demographics. A subset of patients completed a questionnaire pertaining to sexual health.

RESULTS

The study population comprised 327 patients; 269 (82%) patients had a physician-documented sexual history, of which 204 (76%) reported being sexually active to the physician. Patient age (odds ratio [OR]: 2.6 [95% confidence interval (CI): 1.3-5.3]) and black race (OR: 2.0 [95% CI: 1.1-3.7]) were associated with physician-documented sexual history. The documentation of a sexual history was associated with increased STI testing (OR: 3.9 [95% CI: 2.0-7.6]). In the patients (n=109) who completed the questionnaire, physician-elicited sexual histories were highly concordant with patient-documented sexual histories on questionnaire (Spearman r=0.90; P<.001).

CONCLUSION

These results indicate that ED physicians should obtain sexual histories from symptomatic patients, because it may increase STI testing and subsequent detection. In future studies factors should be evaluated that affect physicians' willingness to assess sexual history in the ED patient.

Prevalence of Trichomonas vaginalis infection in symptomatic adolescent females presenting to a pediatric emergency department

OBJECTIVES

Adolescent females are disproportionately affected by sexually transmitted infections (STIs). Although Trichomonas vaginalis (TV) has been declared the most common nonviral STI, TV testing is not routinely conducted in the emergency department (ED), and when it is performed, insensitive testing methods are often used. Therefore, this study sought to determine the prevalence of TV and factors associated with TV infection among symptomatic adolescent females presenting to a pediatric ED.

METHODS

This was a prospective prevalence study of female patients ages 14 to 19 years presenting to a pediatric ED with lower abdominal pain and/or genitourinary (GU) complaints. Patients were tested for TV, Neisseria gonorrhoeae (GC), and Chlamydia trachomatis (CT).

RESULTS

Of the 276 patients who met inclusion criteria, 203 underwent TV testing; prevalence was 9.9% (95% confidence interval [CI] = 5.7% to 14.0%). Assuming all eligible patients who did not have TV testing were not infected with TV, sensitivity analysis revealed a minimum TV prevalence of 7.2% (95% CI = 4.2% to 10.3%). The overall prevalence of any STI was 22.5% (95% CI = 17.5% to 27.4%), with CT being the most prevalent (19.7%; 95% CI = 14.5 to 24.9). Aside from vaginal discharge (odds ratio [OR] = 3.7; 95% CI = 1.1 to 11.3), there were no other factors significantly associated with TV infection.

CONCLUSIONS

A substantial proportion of adolescent females presenting to a pediatric ED with lower abdominal or GU symptoms had TV infection. TV testing should be considered as part of the evaluation of adolescent females presenting to the ED with lower abdominal, urinary, or vaginal complaints.

Technical report--racial and ethnic disparities in the health and health care of children

OBJECTIVE

This technical report reviews and synthesizes the published literature on racial/ethnic disparities in children's health and health care.

METHODS

A systematic review of the literature was conducted for articles published between 1950 and March 2007. Inclusion criteria were peer-reviewed, original research articles in English on racial/ethnic disparities in the health and health care of US children. Search terms used included "child," "disparities," and the Index Medicus terms for each racial/ethnic minority group.

RESULTS

Of 781 articles initially reviewed, 111 met inclusion criteria and constituted the final database. Review of the literature revealed that racial/ethnic disparities in children's health and health care are quite extensive, pervasive, and persistent. Disparities were noted across the spectrum of health and health care, including in mortality rates, access to care and use of services, prevention and population health, health status, adolescent health, chronic diseases, special health care needs, quality of care, and organ transplantation. Mortality-rate disparities were noted for children in all 4 major US racial/ethnic minority groups, including substantially greater risks than white children of all-cause mortality; death from drowning, from acute lymphoblastic leukemia, and after congenital heart defect surgery; and an earlier median age at death for those with Down syndrome and congenital heart defects. Certain methodologic flaws were commonly observed among excluded studies, including failure to evaluate children separately from adults (22%), combining all nonwhite children into 1 group (9%), and failure to provide a white comparison group (8%). Among studies in the final database, 22% did not perform multivariable or stratified analyses to ensure that disparities persisted after adjustment for potential confounders.

CONCLUSIONS

Racial/ethnic disparities in children's health and health care are extensive, pervasive, and persistent, and occur across the spectrum of health and health care. Methodologic flaws were identified in how such disparities are sometimes documented and analyzed. Optimal health and health care for all children will require recognition of disparities as pervasive problems, methodologically sound disparities studies, and rigorous evaluation of disparities interventions.

Toward improving the diagnosis and the treatment of adolescent pelvic inflammatory disease in emergency departments: results of a brief, educational intervention

OBJECTIVE

To assess the utility of an abbreviated teaching tool (ATT) in improving emergency medicine pediatricians' knowledge of the diagnosis and the treatment of pelvic inflammatory disease (PID).

METHODS

An 18-question internet-based survey, which included questions about the diagnosis and the treatment of PID, was administered to members of the American Academy of Pediatrics Section on Emergency Medicine. Participants were randomized to receive either a weblink to the Centers for Disease Control and Prevention (CDC) sexually transmitted disease treatment guidelines (weblink group) or a 1-page ATT that summarized the CDC guidelines (ATT group) to assist with completion of the survey. We compared the accuracy of responses between the 2 groups.

RESULTS

Two hundred thirty-seven subjects responded to the survey (109 from the weblink group and 128 from ATT group). There were no significant differences between the groups with respect to sex, geographic location, practice setting, years of experience, or reported frequency of recent PID diagnoses. Ninety-seven percent of the ATT group correctly identified the appropriate antibiotic regimen in compliance with the CDC guidelines compared with 61% of the weblink group (OR, 19.4; 95% confidence interval, 6.6-76.9); the ATT group was also more likely to correctly identify appropriate treatment options overall (OR, 9.6; 95% confidence interval, 4.9-19.3).

CONCLUSIONS

Although the overall PID knowledge in our sample was low, the physicians with access to a 1-page teaching tool summarizing the CDC treatment recommendations for PID performed significantly better when asked questions involving PID treatment as compared with providers with access to the CDC Web site. Further studies should investigate whether access to a similar tool can improve patient care.

Gonorrhea and chlamydia in emergency departments: Screening, diagnosis, and treatment

Failure to screen sexually active adolescents and adults for gonorrhea and chlamydia at the time of acute care visits to urban emergency departments (ED) results in missed treatment opportunities for 38% to 82% of infected persons. The prevalence of gonorrhea and chlamydia infections among ED patients presenting with genitourinary or pregnancy-related complaints or providing urine specimens as part of routine medical care ranges from 4.3% to 16.4%. Notably, prevalence among general ED patients is similar (9.7%-14.3%). Due to the asymptomatic or nonspecific presentation of these infections, expanded screening is recommended to increase detection, treatment, and partner notification. A lower threshold of empiric treatment in the ED setting is recommended due to the difficulty and incompleteness of follow-up subsequent to ED discharge. Specific recommendations to improve the quality of ED care for sexually transmitted infections and to expand detection are provided.

Diagnosis and treatment of pelvic inflammatory disease

Pelvic inflammatory disease (PID), the infection and inflammation of the female upper genital tract, is a common cause of infertility, chronic pain and ectopic pregnancy. Diagnosis and management are challenging, largely resulting from varying signs and symptoms and a polymicrobial etiology that is not fully delineated. Owing to the potential for serious sequelae, a low threshold for diagnosis and treatment is recommended. As PID has a multimicrobial etiology, including Neisseria gonorrhoeae, Chlamydial trachomatis and anaerobic and mycoplasmal bacteria, treatment of PID should consist of a broad spectrum antibiotic regimen. Recent treatment trials have focused on shorter duration regimens, such as azithromycin, and monotherapies including ofloxacin, but data are sparse. Research comparing sequelae development by differing antimicrobial regimens is extremely limited, but will ultimately shape future treatment guidelines.

Quality of care for common pediatric respiratory illnesses in United States emergency departments: analysis of 2005 National Hospital Ambulatory Medical Care Survey Data

OBJECTIVE

The goal was to measure US emergency department performance in the pediatric care of asthma, bronchiolitis, and croup, by using systematically developed quality indicators.

METHODS

Data on visits to emergency departments by children 1 to 19 years of age with moderate/severe asthma, 3 months to 2 years of age with bronchiolitis, and 3 months to 3 years of age with croup from the 2005 National Hospital Ambulatory Medical Care Survey, with a nationally representative sample of US patients, were analyzed. We used national rates of use of corticosteroids, antibiotics, and radiographs as our main outcome measures.

RESULTS

Physicians prescribed corticosteroids in 69% of the estimated 405,000 annual visits for moderate/severe asthma and in 31% of the estimated 317,000 annual croup visits. Children with bronchiolitis received antibiotics in 53% of the estimated 228,000 annual visits. Physicians obtained radiographs in 72% of bronchiolitis visits and 32% of croup visits.

CONCLUSIONS

Physicians treating children with asthma, bronchiolitis, and croup in US emergency departments are underusing known effective treatments and overusing ineffective or unproven therapies and diagnostic tests.

A Decision Rule to Identify Adolescent Females with Cervical Infections

OBJECTIVE

To develop a clinical decision rule to direct empiric treatment of adolescent females with Neisseria gonorrhoeae (GC) or Chlamydia trachomatis (CT) (or both) cervical infections in a pediatric emergency department.

METHODS

This was a cross-sectional study of adolescent females with symptoms necessitating sexually transmitted infection (STI) testing. The outcome was defined as cervical specimens positive for either GC on culture or CT on nucleic amplification assay test. Clinical variables included demographic, historical, physical, and laboratory findings. Bivariate associations were assessed using chi-square for categorical data and Student's t test for continuous variables. Variables significant at p < 0.5 were eligible for logistic regression (LR). Recursive partitioning (RP) analysis was used to create a clinical decision rule.

RESULTS

Of the 250 subjects, 83 (33.2%) were positive for GC/CT. The adjusted odds ratios (aOR) and 95% confidence intervals (CI) of the LR model were African American race (aOR = 3.2, CI 1.3-7.9), new partner within 3 months (aOR = 1.9, CI 1.0-3.5), cervical discharge (aOR = 2.0, CI 1.1-3.7), absence of yeast forms (aOR = 3.3, CI 1.3-10), and >10 white blood cells (WBCs) (aOR = 2.5, CI 1.3-4.6) on vaginal gram stain. Variables comprising the RP analysis included partner penile discharge, >10 WBCs on vaginal gram stain, African American race, absence of yeast forms on vaginal gram stain, and no hormonal birth control use. This algorithm was 75% sensitive and 71% specific, with a negative predictive value of 85%.

CONCLUSIONS

The LR model confirmed associations seen in other populations. Although STI testing is imperative, the RP model can be used to direct empiric treatment among high-risk adolescent females.
