Prioritizing Evidence-based Interventions for Dissemination and Implementation Investments: AHRQ's Model and Experience.

BACKGROUND: The Agency for Healthcare Research and Quality (AHRQ) is mandated to implement patient-centered outcomes research (PCOR) to promote safer, higher quality care. With this goal, we developed a process to identify which evidence-based PCOR interventions merit investment in implementation. We present our process and experience to date. MATERIALS AND METHODS: AHRQ developed and applied a systematic, transparent, and stakeholder-driven process to identify, evaluate, and prioritize PCOR interventions for broad dissemination and implementation. AHRQ encouraged public nominations, and assessed them against criteria for quality of evidence, potential impact, and feasibility of successful implementation. Nominations with sufficient evidence, impact, and feasibility were considered for funding. RESULTS: Between June 2016 and June 2018, AHRQ received 35 nominations from researchers, nonprofit corporations, and federal agencies. Topics covered diverse settings, populations, and clinical areas. Twenty-eight unique PCOR interventions met minimum criteria; 16 of those had moderate to high evidence/impact and were assessed for feasibility. Fourteen topics either duplicated other efforts or lacked evidence on implementation feasibility. Two topics were prioritized for funding (cardiac rehabilitation after myocardial infarction and screening/treatment for unhealthy alcohol use). CONCLUSIONS: AHRQ developed replicable criteria, and a transparent and stakeholder-driven framework that attracted a diverse array of nominations. We identified 2 evidence-based practice interventions to improve care with sufficient evidence, impact, and feasibility to justify an AHRQ investment to scale up practice. Other funders, health systems or institutions could use or modify this process to guide prioritization for implementation.

Provider Adherence to Syphilis Testing Recommendations for Women Delivering a Stillbirth.

OBJECTIVE: To assess overall adherence to Centers for Disease Control and Prevention and American College of Obstetrics and Gynecology recommended guidelines for syphilis testing among women who delivered a stillbirth and compare it with other tests recommended for stillbirth evaluation. METHODS: We used MarketScan claims data with 40 million commercially insured and 8 million Medicaid enrollees annually to estimate prenatal care and follow-up testing among women who had stillbirths between January 1, 2013, and December 24, 2013. Stillbirth was identified if women had any International Classification of Disease, Ninth Revision codes related to a stillbirth outcome. Among women with stillbirths, we estimated the proportions of women who received prenatal care and prenatal syphilis testing within 280 days before stillbirth, and testing at the time of stillbirth (syphilis testing, complete blood count, placental examination and autopsy) using Physician's Current Procedural Terminology codes. RESULTS: We identified 3672 Medicaid-insured women and 6023 commercially insured women with stillbirths in 2013. Approximately, 61.7% of Medicaid-insured women and 66.0% of commercially insured women had claims data indicating prenatal syphilis testing. At the time of stillbirth, Medicaid-insured and commercially insured women had similar rates of syphilis testing (6.5% vs 9.3%), placental examination (61.6% vs 57.8%), and complete blood count (31.9% vs 37.6%). Autopsies were too infrequent to be reported. Approximately, 34.6% of Medicaid-insured women and 29.7% of commercially insured women had no syphilis testing either prenatally or at the time of stillbirth. CONCLUSIONS: Syphilis testing among women after stillbirth was less than 10%, illustrating limited adherence to Centers for Disease Control and Prevention and American College of Obstetrics and Gynecology recommendations. Such low prenatal and delivery syphilis testing rates may impact the number of stillbirth cases identified as congenital syphilis cases and reported to the national surveillance system. Our results emphasize the need to improve syphilis testing to improve diagnosis of syphilitic stillbirths, identify women with syphilis infection, and provide treatment to these women to avoid syphilis-related adverse outcomes.

Clinical evidence for the role of Trichomonas vaginalis in regulation of secretory leukocyte protease inhibitor in the female genital tract.

BACKGROUND: Secretory leukocyte protease inhibitor (SLPI) is responsible for regulating inflammatory damage to and innate and adaptive immune responses in the vaginal mucosa. Depressed cervicovaginal SLPI levels have been correlated with both Trichomonas vaginalis infection and poor reproductive health outcomes. METHODS: We measured levels of SLPI in 215 vaginal specimens collected from adolescent and young adult females aged 14-22 years. Log-transformed SLPI values were compared by analysis of variance or by an unpaired t test before and after adjustment for confounding effects through the propensity score method. RESULTS: Females receiving hormonal contraceptives and those with an abnormal vaginal pH had lower SLPI levels as compared to their peers. After propensity score adjustment for race, behavioral factors, hormonal use, and other sexually transmitted infections (STIs), SLPI levels were lower in females with a positive T. vaginalis antigen test result, a vaginal pH >4.5, vaginal leukocytosis, and recurrent (vs initial) T. vaginalis infection, with the lowest levels observed in those with the highest T. vaginalis loads. CONCLUSIONS: The SLPI level was reduced by >50% in a T. vaginalis load-dependent manner. Future research should consider whether identifying and treating females with low levels of T. vaginalis infection (before they become wet mount positive) would prevent the loss of SLPI and impaired vaginal immunity. The SLPI level could be used as a vaginal-health marker to evaluate interventions and vaginal products.

Blind evaluation of the microwave-accelerated metal-enhanced fluorescence ultrarapid and sensitive Chlamydia trachomatis test by use of clinical samples.

Accurate point-of-care (POC) diagnostic tests for Chlamydia trachomatis infection are urgently needed for the rapid treatment of patients. In a blind comparative study, we evaluated microwave-accelerated metal-enhanced fluorescence (MAMEF) assays for ultrafast and sensitive detection of C. trachomatis DNA from vaginal swabs. The results of two distinct MAMEF assays were compared to those of nucleic acid amplification tests (NAATs). The first assay targeted the C. trachomatis 16S rRNA gene, and the second assay targeted the C. trachomatis cryptic plasmid. Using pure C. trachomatis, the MAMEF assays detected as few as 10 inclusion-forming units/ml of C. trachomatis in less than 9 min, including DNA extraction and detection. A total of 257 dry vaginal swabs from 245 female adolescents aged 14 to 22 years were analyzed. Swabs were eluted with water, the solutions were lysed to release and to fragment genomic DNA, and MAMEF-based DNA detection was performed. The prevalence of C. trachomatis by NAATs was 17.5%. Of the 45 samples that were C. trachomatis positive and the 212 samples that were C. trachomatis negative by NAATs, 33/45 and 197/212 were correctly identified by the MAMEF assays if both assays were required to be positive (sensitivity, 73.3%; specificity, 92.9%). Using the plasmid-based assay alone, 37/45 C. trachomatis-positive and 197/212 C. trachomatis-negative samples were detected (sensitivity, 82.2%; specificity, 92.9%). Using the 16S rRNA assay alone, 34/45 C. trachomatis-positive and 197/212 C. trachomatis-negative samples were detected (sensitivity, 75.5%; specificity, 92.9%). The overall rates of agreement with NAAT results for the individual 16S rRNA and cryptic plasmid assays were 89.5% and 91.0%, respectively. Given the sensitivity, specificity, and rapid detection of the plasmid-based assay, the plasmid-based MAMEF assay appears to be suited for clinical POC testing.

Point-of-care testing improves accuracy of STI care in an emergency department.

OBJECTIVES: We aimed to examine the impact of a point-of-care (POC) test on overtreatment and undertreatment of sexually transmitted infections (STIs) by comparing treatment patterns for gonorrhoea (detected with nucleic acid amplification testing (NAAT)) with trichomoniasis (detected by POC test) for young women seen in an emergency department (ED). METHODS: We reviewed the database of a quality improvement (QI) project that aims to improve follow-up care for STIs in the ED. Data included the test result and antibiotic given (if any) during visits by women age 14-21 for whom an STI test was ordered. We generated Shewhart control charts and compared overtreatment and undertreatment rates for gonorrhoea and trichomoniasis using χ(2) testing. RESULTS: Of 1877 visits over 18 months, 8.8% of women had gonorrhoea and 16.5% had trichomoniasis. Overtreatment was higher for women with gonorrhoea than trichomoniasis (54% vs 23%, p<0.001). Overtreatment for gonorrhoea decreased from 58% to 47% (p<0.01) and overtreatment for trichomoniasis decreased from 24% to 18% (p<0.01), which corresponded to improvements in patient follow-up for the QI project. Undertreatment was higher for women with gonorrhoea than trichomoniasis (29% vs 21%, p=0.03), and did not change over time. CONCLUSIONS: A POC test improves the accuracy of STI care in an ED compared with NAAT testing. An unanticipated benefit of QI efforts to improve patient follow-up is the observed decrease in antibiotic use in the ED. Given the ability of gonorrhoea to develop antibiotic resistance, future efforts should focus on development of an accurate POC test for gonorrhoea.

Acceptability of self-testing for trichomoniasis increases with experience.

OBJECTIVES: Self-testing and point-of-care (POC) tests could improve the detection of sexually transmitted infections (STIs) in adolescents. This study aimed to (1) validate a scale measuring acceptability of self-testing for trichomoniasis, (2) compare acceptability of self versus clinician testing using a POC test for trichomoniasis, (3) examine changes in acceptability after experience and review of results, and (4) examine predictors of acceptability. METHODS: Women (14-22 years old) performed the POC test and completed surveys assessing acceptability of self and clinician testing at baseline, after testing, and after discussion of results. Factor analysis examined scale structure; changes in mean scale scores were assessed with mixed models. Generalised linear models examined predictors of acceptability. RESULTS: Of 247 participants, 54 (22%) had a positive POC test for trichomoniasis. Factor analysis confirmed four acceptability subscales: trust of results, confidence, comfort, and effects of testing. At baseline, trust and confidence were higher, and comfort was lower, for clinician versus self testing. For self-testing, all subscale scores increased from baseline to after testing, and trust increased from after testing to after discussion. Trust of self and clinician results was not significantly different after discussion. A positive attitude towards home testing predicted higher self-test acceptability on all subscales. Tampon use was associated with increased self-test comfort at baseline. Concordance between self and clinician results predicted increased trust of self testing after discussion. CONCLUSIONS: Many young women lack confidence in their ability to self-test for trichomoniasis. Allowing women to try a POC test and review the results with a clinician increases acceptability of self-testing.

Adolescent women can perform a point-of-care test for trichomoniasis as accurately as clinicians.

OBJECTIVES: To compare the accuracy (ie, correlation, sensitivity, specificity) of self-performed point-of-care (POC) tests with clinician-performed tests for trichomoniasis in adolescent women. METHODS: Sexually experienced women aged 14-22 years (n=209) collected a vaginal swab and performed a POC test for trichomoniasis. Using a speculum, the clinician obtained vaginal swabs that were tested for trichomoniasis using the POC test, wet mount, culture and transcription-mediated amplification (TMA) using standard and alternative primers. Self and clinician results were compared with true positives, defined as either culture-positive or TMA-positive with both sets of primers. RESULTS: Participants' mean age was 17.8 years; 87% were African-American; 74% reported vaginal itching or discharge and 51 (24%) had trichomoniasis. Over 99% correctly performed and interpreted her self-test. Self and clinician POC tests were highly correlated (95.7% agreement, κ 0.87). Compared with true positives, the sensitivity of the self-POC test was 78% (CI 65% to 89%), similar to that of the clinician-POC test (84%, CI 71% to 93%) and culture (82%, CI 69% to 92%), and significantly better than wet mount (39%, CI 26% to 54%). The specificity of the self-POC test was 99% (CI 96% to 100%), similar to that of the clinician-POC test (100%, CI 98% to 100%). The sensitivity of the self-POC test was not affected by vaginal symptoms or other variables. CONCLUSIONS: Young women performing a self-POC test detected as many trichomoniasis infections as clinician-POC tests or culture, twice as many as wet mount and slightly fewer than an amplified test. Incorporating self-obtained or self-performed POC tests into routine practice could effectively increase the identification and treatment of trichomoniasis in this vulnerable population.

Lipschutz ulcers: evaluation and management of acute genital ulcers in women.

Acute genital ulcers are painful and distressing to women and perplexing to the providers who care for them. The differential diagnosis includes sexually and nonsexually transmitted infections, autoimmune conditions, drug reactions, and local manifestations of systemic illness. However, in many cases, no causative agent is identified, and lesions are classified as idiopathic aphthosis. In the setting of fever and acute onset of genital ulcers in girls and women, the term Lipschutz ulcers has been used to describe ulcers associated with an immunologic reaction to a distant source of infection or inflammation. The aims of this article are to review the differential diagnosis and pathogenesis of acute genital ulcers, to offer an evaluation and classification scheme, and to discuss treatment options for the dermatologist who cares for women and girls with vulvar ulcers.

Stepwise diagnosis of Trichomonas vaginalis infection in adolescent women.

The objective of this study was to examine the effects of clinical factors and of the type and timing of a secondary test in improving the sensitivity of Trichomonas vaginalis detection in young women over that of a wet mount alone. For this purpose, sexually active adolescent women (n = 345) were recruited from a hospital teen clinic or emergency department. Following an interview and a pelvic exam, four primary T. vaginalis tests (wet mount, culture, a rapid test, and a nucleic acid amplification test [NAAT]) were performed on vaginal swabs. If the wet-mount result was negative, two secondary tests (culture and a rapid test) were performed on the used wet-mount swab and saline. A positive result by any of the four primary tests was considered a true T. vaginalis-positive result. The prevalence of T. vaginalis was 18.8% overall and 8.8% in the 307 wet-mount-negative women. There was 100% concordance between primary and secondary rapid tests. Secondary culture was 80% sensitive compared to primary culture. The likelihood of a positive rapid test increased with increasing time between specimen collection and testing. A wet mount followed by a rapid test was the most sensitive strategy using two tests (86.4%; confidence interval [CI], 75.3 to 93.4%). Limiting secondary testing to those with multiple partners resulted in a lower sensitivity (73.9%; CI, 61.5 to 84%) that was not significantly better than that of the wet mount alone (58.5%; CI, 45.6 to 70.6%). We conclude that a rapid test can be delayed or performed on a used swab with no loss of sensitivity. Until a NAAT for T. vaginalis is commercially available, a stepwise approach using an additional rapid test for wet-mount-negative women is recommended for adolescent women regardless of clinical factors.

Trichomoniasis in teens: an update.

PURPOSE OF REVIEW: Trichomoniasis, caused by the protozoa Trichomonas vaginalis, is one of the oldest sexually transmitted infections. Since the advent of more accurate diagnostic tests, the epidemiology and consequences of infection with T. vaginalis can be described more precisely. This review will highlight new diagnostic methods, the epidemiology of trichomoniasis, and discuss the merits of improved screening for this pathogen in adolescent women. RECENT FINDINGS: Interest in trichomoniasis has renewed due to evidence that trichomoniasis is more common than gonorrhea in adolescent women, is often asymptomatic, may persist for several months, and may be confused with bacterial vaginosis. In addition, trichomoniasis is linked to pelvic inflammatory disease and can increase one's susceptibility to viruses such as herpes, human papillomavirus, andHIV. SUMMARY: Clinicians who use better diagnostic methods and offer more widespread testing will identify more infections and reduce the epidemic of this easily treated infection. Early diagnosis provides the opportunity to reduce transmission and potentially prevent future complications.

Creation of a Composite Score to Predict Adnexal Torsion in Children and Adolescents.

STUDY OBJECTIVE: To create a composite score to predict adnexal torsion in children and adolescents. DESIGN: A prospective cross-sectional study. SETTING: Emergency department of a tertiary care children's hospital. PARTICIPANTS: Three hundred twenty-four female participants aged 6-21 years who presented to the emergency department with lower abdominal pain and underwent ultrasound or computed tomography imaging. INTERVENTIONS: Collection of possible clinical and radiologic predictors of torsion. MAIN OUTCOME MEASURES: The primary outcome was a composite score to predict adnexal torsion. We used χ2 analyses to identify possible risk factors. The classification and regression tree decision method was used to identify risk factor cutoff points. Independent risk factors were combined into a composite score. Receiver operating characteristic curve analyses were used to assessed score performance. RESULTS: Of 324 participants with abdominal pain, 241 underwent imaging, and 6.6% (16 of 241) had torsion. Duration of pain, intermittent pain, nausea, and absence of arterial or venous flow were not associated with torsion. Vomiting (P = .05 in premenarchal subjects; P < .001 in menarchal subjects), adnexal volume (P = .008 in premenarchal subjects; P < .001 in menarchal subjects), and adnexal volume ratio (P = .04 in premenarchal subjects; P < .001 in menarchal subjects) were independent predictors of torsion. These predictors were incorporated into a composite score. No torsions were identified with a score of less than 2. There was an increasing risk of torsion for each 1-point score increase. CONCLUSION: Independent predictors of torsion can reliably be combined into a composite score to identify children and adolescents at risk for adnexal torsion. This score might aid in improving triage and management of these challenging patients.

Rapid antigen testing compares favorably with transcription-mediated amplification assay for the detection of Trichomonas vaginalis in young women.

BACKGROUND: Diagnosis of Trichomonas vaginalis (TV) infection is limited by imperfect testing methods. Newer tests, such as rapid antigen and nucleic acid amplification tests, are often compared with culture, which is not widely used but is more sensitive than wet mount. We assessed the sensitivity and specificity of 4 tests for the identification of TV using 3 statistical approaches. METHODS: Sexually active adolescent women aged 14-21 years (n=330) were recruited from a teen health center and emergency department. Vaginal swabs were tested for TV using wet mount, culture (InPouch TV; Biomed Diagnostics), rapid antigen testing (OSOM TV; Genzyme Diagnostics), and transcription-mediated amplification testing (TMA; APTIMA TV analyte specific reagents; Gen-Probe). RESULTS: TV was detected in 61 participants (18.5%). Compared with a composite reference standard (i.e., any TV test with positive results), the sensitivities of wet mount, culture, rapid antigen testing, and TMA were 50.8%, 75.4%, 82%, and 98.4%, respectively. Using latent class analysis, the sensitivity of wet mount (56%) was significantly lower than that of other tests, and the sensitivities of culture and rapid antigen testing were similar (83% and 90%, respectively); specificity was 100% for each of these 3 methods. TMA had a sensitivity of 98.2% and a specificity of 98%. Tests performed equally well regardless of whether the participant had bleeding or other infections. The sensitivities of the rapid antigen test and TMA were comparable (92.5% and 97.5%, respectively) in women who had vaginal symptoms. CONCLUSIONS: Wet mount alone is insufficient for the reliable diagnosis of TV infection in women. TMA and rapid antigen tests are highly sensitive and specific, and both are superior to wet mount. Rapid antigen testing is equivalent to culture, and it compares favorably with the sensitivity of TMA for the detection of TV.

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.

Interval to treatment of sexually transmitted infections in adolescent females.

STUDY OBJECTIVE: To describe (1) the treatment interval for adolescent females with Chlamydia trachomatis (CT), Neisseria gonorrhoeae (GC), or Trichomonas vaginalis (TV); (2) the proportion treated in < or =7 days; and (3) factors influencing the treatment interval. DESIGN AND PARTICIPANTS: Charts of sexually active females from an urban teen health center who participated in a larger study and were positive for CT, GC or TV (N = 58) were retrospectively reviewed for dates of treatment, and compared to demographic and symptom data. The treatment interval was defined as days from visit to treatment. CT and/or GC were analyzed together (CT/GC) because presumptive treatment covered both infections, and the diagnostic test (nucleic acid amplification) differed from that of TV (wet mount or culture). RESULTS: The median treatment interval was 0 days for TV, 5 days for CT/GC, and 3 days for any STI. Overall, 39 (69%) were treated within 7 days of their visit. Those with TV were more likely than those with CT/GC to receive treatment at their initial visit (58% vs. 6%). Genitourinary symptoms increased the odds of treatment in < or =7 days. The treatment interval was significantly shorter for subjects who had their prescriptions phoned to a pharmacy than for those who returned to clinic for treatment (median 2.5 vs. 8 days). CONCLUSIONS: Where presumptive treatment was uncommon, providers were more likely to prescribe same-day therapy to symptomatic patients or those with TV on wet mount. Additional strategies are needed to improve the proportion of adolescent females treated in < or =7 days.

The Impact of the American College of Obstetricians and Gynecologists Guideline Changes in Pap Tests on Annual Chlamydia Test Rates.

PURPOSE: To assess impact of the 2009 American College of Obstetricians and Gynecologists (ACOG) Pap guideline changes on chlamydia testing rates among sexually active young women. METHODS: The study included sexually active women aged 15-25 years enrolled in commercial health plans from 2005 to 2014. We identified sexually active women by diagnosis, procedure, and drug codes in inpatient, outpatient, and drug claims databases. We identified Pap tests and chlamydia tests among sexually active adolescents (15-20 years) and young adults (21-25 years) over time. Using piecewise regression models, we compared the change in chlamydia testing rates before and after 2009 ACOG guidelines. RESULTS: From 2005 to 2014, chlamydia testing rates in sexually active women increased from 23% to 37% among adolescents and from 24% to 43% among young adults. Although the overall increase in chlamydia testing was positive, the annual rate of change in chlamydia testing (slope) decreased significantly after the 2009 ACOG guideline change from 1.9% before to 1.0% after for adolescents (p < .05) and from 2.5% to 1.7% for young adults (p < .05). CONCLUSIONS: Although chlamydia test rates are increasing among sexually active women aged 15-25 years from 2005 to 2014, the slower growth in chlamydia testing rate after 2009 may relate to the change in the Pap testing guidelines. Our finding that more than half of sexually active women aged 15-25 years did not have chlamydia testing and that the rate of increased chlamydia testing slowed after 2009 suggests that interventions to improve chlamydia testing apart from combining with Pap testing are still needed.

Vulvar ulcers in young females: a manifestation of aphthosis.

STUDY OBJECTIVE: To examine the etiology, clinical course, and outcomes of non-sexually transmitted vulvar ulcers in young females. DESIGN: A prospective cohort study of subjects referred to a tertiary center who had active vulvar ulcers and no evidence of sexually transmitted infections were evaluated with a structured clinical and laboratory protocol and followed with visits or telephone calls. RESULTS: Twenty eligible subjects had a mean age of 14 years (range 10-19), and five were premenarchal. Nineteen reported systemic symptoms such as fever, malaise, and headache. Most ulcers were >1cm in diameter (range 0.3-5 cm) and were located on the medial aspect of the labia minora. All viral, bacterial, and fungal cultures were negative. Serologic testing for Epstein-Barr virus (EBV) infection demonstrated 10 subjects with evidence of prior infection, two with acute infection, one indeterminate, and seven negative for infection. Two subjects had evidence of possible acute cytomegalovirus (CMV) infection. Other laboratory findings were nonspecific. The median duration of pain was 10 days (range 6-30), and 75% healed by 21 days. Follow up was available for 19 subjects (median 14 months). Seven experienced recurrent ulcers 2-16 months after the initial episode, and 10 had experienced oral aphthous ulcers. None met criteria for other etiologies of vulvar ulcers reported in the literature. CONCLUSIONS: No single infectious agent was identified as a cause of vulvar ulcers. Most cases were not temporally associated with either acute EBV or CMV infection. These ulcers are consistent with aphthous major or complex aphthosis that arise in response to acute illness.

Sexually transmitted infection testing and screening in hospital-based primary care visits by women.

OBJECTIVE: To explore determinants of sexually transmitted infection screening of asymptomatic women and sexually transmitted infection testing of women with genitourinary symptoms, to investigate the effect of specific genitourinary symptoms on sexually transmitted infection testing, and to examine trends in screening. METHODS: We performed secondary data analysis of nationally representative data from the National Hospital Ambulatory Medical Care Surveys, using 17,458 visits by nonpregnant 15- to 44-year-old women seen in primary care clinics between 1997 and 2000. Point estimates, adjusted odds ratios (ORs) and 95% confidence intervals (CIs) are presented. RESULTS: Sexually transmitted infection screening was performed in 2.4% of visits by women without genitourinary symptoms and was more likely among visits for preventive care (OR 6.9, CI 3.8-12.5), by nonwhite women (OR 4.3, CI 2.3-7.9), and in gynecology clinic (OR 3.9, CI 2.5-6.1). Sexually transmitted infection testing occurred in 13.2% of visits by women with genitourinary symptoms and was associated with Medicaid (OR 2.3, CI 1.4-3.6), preventive care (OR 2.0, CI 1.2-3.2), patient age less than 25 years (OR 1.7, CI 1.0-2.6), and nonwhite race (OR 1.7, CI 1.0-2.6). Among symptomatic women, vaginal symptoms (OR 4.8, CI 2.6-8.9) and abdominal/pelvic pain (OR 2.5, CI 1.4-4.5) were associated with sexually transmitted infection testing. Between 1997 and 2000, sexually transmitted infection screening rates remained stable. CONCLUSION: Despite national guidelines, sexually transmitted infection testing outpaces screening. Few visits by asymptomatic women under age 25 result in screening. Strategies to improve screening in primary care should target nongynecology settings and non-preventive care visits. LEVEL OF EVIDENCE: III.

Adolescent use of the monthly contraceptive injection.

STUDY OBJECTIVE: To compare weight and continuation among adolescents using monthly medroxyprogesterone acetate (MPA)/ethinyl estradiol cypionate (E2C), tri-monthly depot MPA (DMPA), and daily oral contraceptive pills (OCP). DESIGN: Medical records were reviewed for body mass index, demographics, and sexual history at baseline; and weight and continuation at 3, 6, 9, and 12 months. Bivariate analyses were performed by method, and continuation functions were compared by the log-rank and Wilcoxon tests. The effect of method on use duration was assessed by Cox regression. SETTING: Hospital adolescent clinic. PARTICIPANTS: 12- to 21-year-old patients who initiated MPA/E2C, DMPA, or OCPs in 2001. MAIN OUTCOME MEASURES: Weight gain and method continuation. RESULTS: MPA/E2C was initiated by 40 (18%) patients, DMPA by 63 (28%), and OCPs by 119 (54%, P < 0.001). OCP users were younger (P = 0.005) and more likely to be white, privately insured, and in school (P < 0.004) than MPA/E2C or DMPA users. Previous DMPA and OCP use, pregnancy, and sexually transmitted infections (STI) were more common among MPA/E2C than DMPA or OCP users (P < or = 0.001). Baseline BMI was lowest (P = 0.06) among DMPA users, and MPA/E2C users were most likely to be overweight (P = 0.03). There were non-significant differences in weight change. Continuation functions differed by the method only in the first three months of use (P = 0.03). Leading reasons for discontinuation were unavailability of MPA/E2C (20%), bleeding with DMPA (22%), and forgetting OCPs (17%). Duration of use was independently associated with white race (P < 0.005) and STI-never (P < 0.0001) but not with method type. CONCLUSIONS: Although MPA/E2C use was associated with overweight status and early discontinuation, it also was associated with previous use of other methods. For all methods, poor continuation at one year supports the ongoing search for effective contraceptive alternatives.

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.
