A New Strategy for Trichomonas Testing Female Adolescents in the Emergency Department

Prediction model for gonorrhea, chlamydia, and trichomoniasis in the emergency department

OBJECTIVE

History and physical examination findings can be unreliable for prediction of genitourinary tract infections and differentiation of urinary tract infections from sexually transmitted infections (STIs). The study objective was to develop a prediction tool to more accurately identify patients with STIs.

METHODS

A retrospective review of 64,490 emergency department (ED) encounters between April 18, 2014, and March 7, 2017, where patients age 18 years or older had urinalysis and urine culture or testing for gonorrhea, chlamydia, or trichomonas, was used to develop a prediction model for men and women with Neisseria gonorrhoeae or Chlamydia trachomatis, or both, and for women with Trichomonas vaginalis. The data set was randomly divided into two-thirds discovery and one-third validation. Groups were assigned through a random number generator. Backward step regression modeling was used to identify the best model for each outcome.

RESULTS

With use of age, race, marital status, and findings from vaginal wet preparation (white blood cells [WBCs], clue cells, and yeast) and urinalysis (squamous epithelial cells, protein, leukocyte esterase, and WBCs), the models had areas under the receiver operating characteristic curve of 0.80 for men with N gonorrhoeae or C trachomatis, or both; 0.75 for women with N gonorrhoeae or C trachomatis, or both; and 0.73 for women with T vaginalis.

CONCLUSIONS

The model estimated likelihood of ED patients having STIs was reasonably accurate with a limited number of demographic and laboratory variables. In the absence of point-of-care STI testing, use of a prediction tool for STIs may improve antimicrobial stewardship.

Vaginal leukocyte counts for predicting sexually transmitted infections in the emergency department

BACKGROUND

The use of vaginal white blood cell (WBC) counts to predict sexually transmitted infections (STIs) in the emergency department (ED) is incompletely characterized.

OBJECTIVES

Our objective was to assess the relationship between vaginal wet preparation WBC counts and STIs and to determine whether WBC counts of at least 11 WBCs per high-power field (HPF) could be useful for identifying STIs in women in the ED.

METHODS

Female ED patients 18 years or older who were evaluated in a single health system between April 18, 2014, and March 7, 2017, and had a genital wet preparation WBC result were retrospectively examined using univariable and multivariable analysis.

RESULTS

Vaginal wet preparation WBC counts were examined for 17,180 patient encounters. Vaginal WBC counts of at least 11 WBCs/HPF were associated with increased odds of having gonorrhea, chlamydia, or trichomoniasis. When this threshold was used for the diagnosis of each STI, sensitivity ranged from 48.2% to 53.9%, and specificity ranged from 67.2% to 68.8%.

CONCLUSION

Women with STIs are more likely to have higher vaginal WBC counts. However, higher vaginal wet preparation WBC counts in isolation have limited diagnostic utility for gonorrhea, chlamydia, and trichomoniasis. Incorporation of age, urine leukocyte esterase results, and vaginal WBC counts provided a better predictor of an STI than vaginal WBC counts alone.

A Research Agenda for Emergency Medicine-based Adolescent Sexual and Reproductive Health

OBJECTIVE

The objective was to identify key questions for emergency medicine (EM)-based adolescent sexual and reproductive health and to develop an evidence-based research agenda.

METHODS

We recruited national content experts to serve as advisory group members and used a modified Delphi technique to develop consensus around actionable research questions related to EM-based adolescent reproductive and sexual health care. Author subgroups conducted literature reviews and developed the initial list of research questions, which were iteratively refined with advisory members. External stakeholders then independently rated each item for its importance in expanding the evidence base (1 = not important to 5 = very important) via electronic survey.

RESULTS

Our final list of 24 research questions included items that intersected all sexual and reproductive health topics as well as questions specific to human immunodeficiency virus/sexually transmitted infections (HIV/STIs), pregnancy prevention, confidentiality/consent, public health, and barriers and facilitators to care. External stakeholders rated items related to HIV/STI, cost-effectiveness, brief intervention for sexual risk reduction, and implementation and dissemination as most important.

CONCLUSIONS

We identified critical questions to inform EM-based adolescent sexual and reproductive health research. Because evidence-based care has potential to improve health outcomes while reducing costs associated with HIV/STI and unintended pregnancy, funders and researchers should consider increasing attention to these key questions.

Sexually Transmitted Infections: Prevention, Diagnosis, and Treatment in Primary Care

Most adolescents are cared for by general pediatricians, family practitioners, and mid-level providers. As a result, primary care practitioners need to be prepared to answer questions from adolescent patients and their parents about sexually transmitted infections (STIs), to practice good preventive medicine through screening and vaccination, and to provide treatment of STIs when needed. Although the topic of STIs is broad, there are common scenarios that arise in adolescent care. This review takes a pragmatic look at some of the most routine topics in adolescent health care regarding STIs, including the provision of confidential care, discussions with adolescent patients and their parents about human papillomavirus vaccination, the diagnosis and treatment of urethritis and cervicitis, and STI screening recommendations.

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.
