Sexual History Documentation Research Articles

Sexual History Documentation in Pediatric Patients with Technology Dependence.

Adolescent sexual health documentation reflects the depth of discussion physicians conduct with their patients. Limited studies exist on rates of sexual history documentation in technology-dependent patients. We sought to identify whether treatment gaps exist in a technology-dependent adolescent population. Well-child visits for patients with enterotomy or tracheostomy dependence, 12 to 19 years age, and seen in our urban clinic over a 3-year period (n = 14) were compared with a randomly selected peer group without technology dependence. Documentation of sexual activity, sexual orientation, safe sex and sexually transmitted infection (STI) guidance, and contraception or condom use were noted. Results demonstrate lower rates of documentation in sexual orientation, safe sex and STI guidance, and contraception or condom use in patients with technology dependence when compared with patients without technology dependence. Similar differences were noted in the 16- to 19-year group between the experimental and control groups. No differences were noted between gender and age groups.

Improving Sexual History Documentation in Teenagers.

Teen access to sexual health care is essential. The 21st Century Cures Act mandates that most electronic health information be shared with patients; no standard exists for how to meet this mandate for teens and their proxy caregivers. Our confidential shared teen sexual history (SexHx) section, which is not note-based, allows clinicians to easily find information, promotes clinical decision support, and protects privacy. Nevertheless, significant variability existed in SexHx section usage, SexHx documentation, and teen note-sharing practices. For teens (aged 12-17) admitted to the Pediatric Hospital Medicine service, we aim to increase the use of the SexHx section by 10% and increase History and Physical notes (H&Ps) shared with teens by 5% over 12 months. Quality improvement methodology and tools were used to conduct a barrier analysis and implement a series of interventions, which included education, training, and electronic health record clinical decision support. Statistical process control charts were used to examine the impact of the interventions. At baseline, from April to July 2021, sexual activity was documented or reviewed in the SexHx section for 56% of teen patients. Over the intervention period, the center line shifted to 72%. At baseline, 76% of teen H&Ps were shared with patients. The percentage of H&Ps shared revealed a center-line shift to 81% throughout the intervention period. The shared teen SexHx section is an innovative tool for capturing sensitive patient history discretely. We demonstrated increased and sustained SexHx section use and H&P note-sharing in this quality improvement initiative.

Increasing Chlamydia and Gonorrhea Testing for Adolescents in the Pediatric Emergency Department.

Adolescents who use the emergency department are more likely to engage in high-risk sexual activity and are at an increased risk of sexually transmitted infections. We aimed to increase testing for Chlamydia and gonorrhea from 12% to 50% among adolescents presenting to our pediatric emergency department with at-risk chief complaints over 12 months. Plan-Do-Study-Act cycles were initiated in July 2020. A multidisciplinary team reviewed preexisting data and developed interventions to increase Chlamydia and gonorrhea testing in teens with at-risk complaints, including genitourinary and behavioral health complaints, and females with abdominal pain. Two categories of interventions were implemented: education and electronic medical record optimization. Process measures were the proportion of patients with a documented sexual history and the proportion of patients tested with a documented confidential phone number. Secondary outcome measures included the weekly number of positive test results and the proportion of patients testing positive who were contacted to arrange treatment. Statistical process control charts were used to examine changes in measures over time. Within 14 months of project initiation, the proportion of at-risk patients tested increased from 12% to 59%. Teen phone number documentation remained unchanged from 23%. Sexual history documentation remained unchanged from 46%. The number of positive test results increased from 1.8 to 3.4 per month, and the proportion of patients testing positive who were contacted to arrange treatment remained unchanged at 83%. We surpassed our goal and increased the proportion of at-risk patients tested for Chlamydia and gonorrhea to 59%, sustained for 4 months from the last intervention.

Associations Between Sexual History Documentation in Electronic Health Records and Referral to Pre-Exposure Prophylaxis Navigator on Prescription of Pre-Exposure Prophylaxis at a Multi-Site Federally Qualified Health Center.

This cross-sectional study examined the relationships between sexual history screening (SHS) and referrals to a pre-exposure prophylaxis (PrEP) navigator (non-clinical staff member who assists patients in overcoming structural barriers to PrEP) on the proportion of days covered by PrEP for adult patients at a federally qualified health center. Patients' sociodemographics, PrEP prescriptions, referral to a PrEP navigator, and SHS data were extracted from the electronic health record (EHR). The analytic sample was 214 adult patients who were human immunodeficiency virus (HIV) negative and taking PrEP to prevent infection from January 2016 to December 2019. Mixed-effects negative binomial models were conducted accounting for clustering by patients' primary care providers. Documentation of SHS was associated with a higher proportion of days covered by PrEP (incidence rate ratio = 1.44, 95% confidence interval: 1.17-1.77). There was no significant effect of having a referral to the PrEP navigator on the proportion of days covered by PrEP, nor did having a referral to the PrEP navigator moderate the relationship between having SHS documented in the EHR and the proportion of days covered by PrEP. This study is the first to investigate the relationship between having sexual history documented in the EHR, referrals to a PrEP navigator, and their combined effect on the proportion of days covered by PrEP. Results of this study provide foundational evidence for future studies examining SHS as an opportunity to improve PrEP access and adherence and indicate the need for additional research exploring the value of PrEP navigators as an implementation strategy to overcome social and structural barriers to care.

Current Inpatient Screening Practices for Sexual History and STIs: An Opportunity to Seize.

The American Academy of Pediatrics recommends utilizing hospitalizations as an opportunity to provide sexual health screenings for adolescents. This study aimed to describe the current practice of sexual history documentation (SHxD) and sexually transmitted infection (STI) testing among adolescents admitted to a pediatric hospital medicine service. Retrospective cross-sectional study of adolescents (14-19 years old) admitted to the PHM service from 2017-2019 was performed at an academic children's health system. Patient (demographics, history of complex chronic condition, and insurance), hospitalization (length of stay, diagnosis, STI tests ordered/results), and physician (level of training and gender) characteristics were extracted for each encounter. A natural language processing algorithm identified the presence of SHxD. Univariate analysis and multivariable analysis were performed to detect factors associated with SHxD and STI screening. The prevalence of STIs was calculated for those who were tested. Out of 2242 encounters, SHxD and STI testing rates were 40.9% and 17.2%, respectively. Patient gender, race, lack of complex chronic condition, and resident involvement were predictive of SHxD and STI testing. SHxD increased the odds of STI testing significantly (OR 5.06, CI 3.90-6.58). Among those who were tested, the prevalence of STIs was highest for chlamydia (37/329, 11.2%). Overall, sexual health screening rates remain low in the hospital setting and future improvement initiatives are needed.

Using Electronic Health Record Modifications to Increase Use of Adolescent Sensitive Notes.

Confidentiality is imperative when caring for adolescents, yet the 21st Century Cures Act ensures guardian access to some of their child's documentation. Pediatric Hospital Medicine (PHM) history and physical (H&P) notes are visible to guardians, whereas adolescent sensitive notes (ASN) are not. Our aim was to decrease sexual history and substance use (SHSU) documentation in H&P notes. This quality improvement study included adolescents ages 13 to 17 from August 1, 2020 to May 31, 2021. Interventions included disappearing help text added to PHM H&P template prompting placement of positive SHSU in the ASN, editing of disappearing help text to encourage copy and paste of all SHSU into ASN, and communication to providers. The primary outcome measure was documentation of SHSU in H&P notes. The process measure was presence of ASNs. The balancing measures were documentation of unapproved social history domains in the ASN and encounters with no SHSU documentation. Statistical process control was used for analysis. Four hundred fifty patients were included in this analysis. There was decreased documentation of SHSU within H&P notes from means of 58.4% and 50.4% to 8.4% and 11.4%, respectively. There was increased utilization of ASN from 22.8% to 72.3%. Special cause variation occurred. Other unapproved domains in the ASN decreased. Encounters with no SHSU were unchanged. The quality improvement intervention of disappearing help text in PHM H&Ps was associated with decreased documentation of SHSU within H&P notes and increased utilization of ASN. This simple intervention helps maintain confidentiality. Further interventions may include utilization of disappearing help text in other specialties.

After "The Talk": Adolescents' Perspectives Reveal Need for Improvement in Hospital Sexual Health Care Delivery.

To fill access gaps for adolescents, addressing sexual and reproductive health (SRH) is recommended in nontraditional settings. In previous improvement work, we increased documentation of sexual history to >80% of adolescents hospitalized on our pediatric hospital medicine (PHM) service. This study assessed adolescents' perception of SRH conversations with hospital providers and the extent to which they were helpful. Postdischarge survey of patients 13 to 17 years discharged from the PHM service at an academic children's hospital between August 2019 and March 2020. Survey items included demographics; whether confidential discussion of sexual health topics such as contraception, sexually transmitted infection (STI), and sexual orientation occurred; perceptions of these discussions, and sexual history. Eighty-three patients enrolled and 44 (53%) completed the survey after discharge. A total of 68% of respondents were female and median age was 15 years (interquartile range 14-16). A total of 77% reported discussing SRH privately with a PHM provider. A total of 18% recalled discussing condoms, and 63% rated the discussion helpful. A total of 27% of females reported discussing birth control, and 40% rated it helpful. A total of 57% recalled discussing sexual orientation, and 40% rated it helpful. None reported discussions of STI testing with PHM. Of the 23% who were sexually active, none reported being given condoms. Analysis of adolescent patient experiences identified opportunities for continued improvement in the content and quality of SRH discussions, specifically regarding offering STI testing, condom distribution, and sexual orientation conversations. Our work highlights the importance of incorporating patient-reported data into improvement work to ensure providers are addressing targeted gaps in adolescent care.

Sexual History Documentation and Screening in Adolescent Females with Suicidal Ideation in the Emergency Department.

Adolescents with mental illness often seek care in the emergency department (ED) and are more likely to engage in risky behaviors such as substance abuse and unprotected sex, increasing their risk of sexually transmitted infections (STI), unintended pregnancy, and non-consensual sex. This was a retrospective study of 312 females, aged 13–17 years, presenting to the pediatric ED with the chief complaint of suicidal ideation from February to May 2018. Electronic medical records were reviewed for demographics, psychiatric history, sexual history, and testing for pregnancy or STI. The primary outcome was the documentation of the presence or absence of prior sexual activity. Secondary outcomes included documented aspects of sexual history and pregnancy or STI testing performed in the ED. Of the 312 eligible patients, 144 (46.2%) had a documented sexual history, and of those 50 (34.7%) reported being sexually active. Sexual history documentation was not associated with patient age, race, ethnicity, insurance, or the gender of the ED provider. A history of anxiety and a recent suicide attempt were associated with a lack of sexual history documentation (p = 0.03). Of the sexually active patients, 28 (56%) had documentation of contraception use. Pregnancy testing was performed in 67.3% of all patients and 80% of sexually active patients. Only 10 patients had STI testing in the ED, with most testing occurring in those with sexual history documentation (p = 0.007). In conclusion, more than half of females with suicidal ideation in our ED had no documentation of sexual history, and when documentation was completed, it was often missing important elements, including screening for pregnancy, STI, non-consensual sex, and contraception use. Since the ED visit provides an important opportunity to address the reproductive health needs of this high-risk population, further work is needed to determine ways to improve provider documentation and sexual health screening.

A method to advance adolescent sexual health research: Automated algorithm finds sexual history documentation.

Background:We aimed to develop and validate a rule-based Natural Language Processing (NLP) algorithm to detect sexual history documentation and its five key components [partners, practices, past history of sexually transmitted infections (STIs), protection from STIs, and prevention of pregnancy] among adolescent encounters in the pediatric emergency and inpatient settings.MethodsWe iteratively designed a NLP algorithm using pediatric emergency department (ED) provider notes from adolescent ED visits with specific abdominal or genitourinary (GU) chief complaints. The algorithm is composed of regular expressions identifying commonly used phrases in sexual history documentation. We validated this algorithm with inpatient admission notes for adolescents. We calculated the sensitivity, specificity, negative predictive value, positive predictive value, and F1 score of the tool in each environment using manual chart review as the gold standard.ResultsIn the ED test cohort with abdominal or GU complaints, 97/179 (54%) provider notes had a sexual history documented, and the NLP algorithm correctly classified each note. In the inpatient validation cohort, 97/321 (30%) admission notes included a sexual history, and the NLP algorithm had 100% sensitivity and 98.2% specificity. The algorithm demonstrated >97% sensitivity and specificity in both settings for detection of elements of a high quality sexual history including protection used and contraception. Type of sexual practice and STI testing offered were also detected with >97% sensitivity and specificity in the ED test cohort with slightly lower performance in the inpatient validation cohort.ConclusionThis NLP algorithm automatically detects the presence of sexual history documentation and its key components in ED and inpatient settings.

A Missed Opportunity: Extragenital Screening for Gonorrhea and Chlamydia Sexually Transmitted Infections in People With HIV in a Southeastern Ryan White HIV/AIDS Program Clinic Setting.

BackgroundGuidelines recommend annual screening for gonorrhea/chlamydia in sexually active people with HIV at multiple sites (urogenital, oropharyngeal, rectal). In the first year of multisite screening at our Ryan White HIV/AIDS Program clinic, we studied (1) sexual history documentation rate, (2) sexually transmitted infection (STI) screening rate, (3) characteristics associated with STIs, and (4) the percentage of extragenital STIs that would have been missed without multisite screening.MethodsParticipants were ≥14 years old with ≥1 in-person medical visit at our clinic in 2019. Descriptive analyses were performed, and adjusting for number of sites tested, a log-binomial model was used to estimate the association between characteristics and STI diagnosis in men.ResultsIn this cohort (n = 857), 21% had no sexual history recorded. Almost all STI diagnoses were among males (99.3%). Sixty-eight percent (253/375) received appropriate urogenital testing, 63% (85/134) received appropriate oropharyngeal testing, and 69% (72/105) received appropriate rectal testing. In male participants with ≥1 STI test (n = 347), Hispanic ethnicity and having a detectable HIV viral load were associated with an STI diagnosis. Of those diagnosed with an STI who had multisite testing, 96% (n = 25/26) were positive only at an extragenital site.ConclusionsScreening rates were similar across all anatomical sites, indicating no obvious bias against extragenital testing. In males, STIs were more frequently diagnosed in people who identify as Hispanic and those with detectable viral loads, which may indicate more condomless sex in these populations. Based on infections detected exclusively at extragenital sites, our clinic likely underdiagnosed STIs before implementation of multisite screening.

Improving Sexually Transmitted Infection Screening in Inpatient Pediatric Patients.

Sexually transmitted infections (STIs) are a group of infectious diseases that cause acute illness and lifelong health effects. Half of the diagnosed cases occur in adolescents and young adults, ages 15 to 24. The American Academy of Pediatrics and the Centers for Disease Control and Prevention provide guidelines for STI screening for sexually active adolescents. Despite this, screening rates in adolescents admitted to our hospital are low. The purpose of this study is to use quality improvement methodology to improve the percent of adolescent patients who had documentation of sexual histories from 49% to 69% and STI testing from 29% to 49%. Eligible patients included adolescents ages 14 to 18 admitted to our hospital's academic general pediatric service. After baseline data collection, we introduced a series of 6 interventions; percentages of sexual history documentation and STI screening were recorded monthly. Interventions included resident education on STI screening, history, and physical form prompts for sexual history documentation, "badge buddy" sexual history templates, faculty development, and an electronic medical record template. Data were interpreted by using statistical process control to show process change. Before the interventions, 48.7% of patients ages 14 to 18 had sexual histories documented; 29.1% of patients were tested for STIs. After interventions, there was a special cause variation resulting in new center lines of 67.1% and 49.1%, respectively. Simple interventions to normalize and standardize adolescent sexual history discussions cumulatively led to a significant increase in sexual history documentation and STI screening in an inpatient adolescent population.

Racial Disparities in the Emergency Department Evaluation of Adolescent Girls.

Racial disparities and differences exist in emergency care. Obtaining a sexual history is standard of care for adolescents with abdominal pain. Testing for sexually transmitted infections (STIs) and pregnancy should be based on historical findings. The objective of this study was to determine whether differential care was provided to adolescent female patients with abdominal pain based on patient race or healthcare provider characteristics by evaluating the documentation of sexual history, STI testing, and pregnancy testing. This was a retrospective chart review of female patients between the ages of 14 and 18 years with abdominal pain presenting to a pediatric emergency department. Patient and provider characteristics, sexual history documentation, STI, and pregnancy testing were abstracted. Data were analyzed using χ 2 test and logistic regression model. Eight hundred eighty-six encounters were included in the analysis. Median patient age was 16 years (range, 14-18 years); 359 (40.5%) were non-White. Differential care was provided. Non-White patients compared with White patients were more likely to have a documented sexual history (59.9% vs 44.0%, P < 0.001), STI testing (24.8% vs 7.8%, P < 0.001), and pregnancy testing (76.6% vs 66.2%, P < 0.001). Among sexually active female patients, the racial disparity for STI testing persisted ( P = 0.010). Provider type and sex did not result in differences in sexual history documentation, STI, or pregnancy testing for non-White compared with White patients ( P > 0.05). Differential care was provided to non-White adolescents with abdominal pain compared with White adolescents. They were more likely to have a documented sexual history, STI testing, and pregnancy testing. Healthcare provider characteristics did not impact patient care. This racial disparity resulted in better medical care for non-White adolescents, but this may be the consequence of underlying implicit bias.

Implementation of an Inpatient Reproductive Health Screening Consult Service.

Reproductive health is an important issue in the care of adolescents and young adults (AYA). Unfortunately, many AYAs, particularly those with chronic medical conditions, may not regularly access primary care to address these issues. This study evaluates the impact of an inpatient reproductive health consult service on reproductive health care. A reproductive health-focused screening consult service was initiated in June 2017 at an academic teaching hospital. Patients aged 15 to 26 admitted to pediatric ward teams were eligible for screening. A retrospective chart review was conducted from December 2016 to June 2019 to determine the effect of the consult service on the primary outcome, documentation of a psychosocial assessment, and reproductive health concerns. Nine hundred twenty-nine encounters were analyzed (345 preintervention and 584 during intervention), representing 675 patients. The proportion of encounters with a documented psychosocial assessment increased from 14.8% to 41.3% during the intervention (P < .001); a reproductive health screening consult was responsible for 37.3% (109 of 292) of the documented assessments. There were high self-reported rates of sexual activity (38%), substance use (47%), and mood concerns (48%) among hospitalized AYA; all behaviors were documented at statistically significant increased frequencies (P < .001) during the intervention compared with preintervention. Initiation of an inpatient reproductive health screening consult service led to increased documentation of psychosocial assessments, including increased documentation of sexual health history and other risk factors. With improved screening of reproductive and psychosocial needs, targeted interventions can meet underrecognized needs among hospitalized AYA.

Sexual History Documentation and Sexually Transmitted Infection Screening for Mental Health Patients in a Pediatric Emergency Department.

Adolescents with psychiatric conditions more commonly engage in high-risk sexual behaviors and are at increased risk of sexually transmitted infections (STIs) and when presenting to pediatric emergency departments (PEDs) may be an important population in which to target screening efforts. This study aimed to determine frequency of physician-documented sexual history and STI screening in adolescents presenting to a PED with mental health-related complaints. Retrospective study of patients aged 14 to 18 years presenting to a PED February 2015 to September 2016. Electronic records were reviewed for demographics, chief complaint, sexual history documentation, STI screening, resident involvement in patient care, and disposition. Proportions were calculated for frequencies, whereas χ2 and Fisher exact tests evaluated factors associated with documentation of sexual history and STI screening. Two hundred eighty-five patient encounters were identified. Age range was 15 to 18 years with an average of 16 years, and 58% were girls. The most common chief complaint was "intentional ingestion/overdose" (169 encounters, 59%) followed by "suicidal/attempted suicide" (59, 21%). Seventy-seven patients (27%) had sexual history documented. Girls were more likely to have sexual history documented (75% vs 52%, P = 0.0004). Forty-five (59%) patients were noted to be sexually active, and 17 (38%) of these were screened for STI. There was no relationship between screening and race, sex, or involvement of a resident in patient care. In a high-risk PED population, physicians documented sexual history only 27% of the time. Female patients were more likely to have a sexual history documented. In patients with sexual history indicating risk for STI, less than half were screened.

Quality Initiative to Increase Delivery of Adolescent Hospital-Based Reproductive Health Care.

Hospitals are an important nontraditional setting in which to address adolescent reproductive health. However, opportunities for intervention are frequently missed, especially for boys and patients hospitalized for noningestion complaints. Our global aim was to increase delivery of reproductive health care to adolescents hospitalized through our children's hospital Pediatric Hospital Medicine service. We performed 2 quality improvement intervention cycles: (1) provider education and monthly reminder e-mails and (2) an automated electronic health record (EHR) adolescent history and physical note template with social history prompts while discontinuing reminder e-mails. The primary outcome measure was sexual history documentation (SHD). Secondary measures were sexually transmitted infection (STI) testing and contraception provision. Statistical process control charts were used to analyze effectiveness of interventions. From July 2018 through June 2019, 528 Primary Hospital Medicine encounters were included in this study and compared with published baseline data on 150 encounters. Control charts revealed a special cause increase in SHD from 60% to 82% overall, along with 37% to 73% for boys and 57% to 80% for noningestion hospitalizations. Increased SHD correlated with cycle 1 and was maintained through cycle 2. Percent STI testing significantly increased but did not shift or trend toward special cause variation. Contraception provision, length of stay, and patient relations consultations were not affected. The interventions were successful in increasing SHD, including among boys and noningestion hospitalizations. The EHR enhancement maintained these increases after reminder emails were discontinued. Future interventions should specifically address STI testing and provision of contraception.

Variability in Sexual History Documentation in a Primary Care Electronic Health Record System

PurposeWe sought to evaluate sexual history documentation and corresponding Chlamydia trachomatis screening practices across a large pediatric primary care network in the context of patient and clinic characteristics. MethodsDemographic, chlamydia screening, and provider note data were collected via electronic health record and manual chart audit for females aged 15-19 years attending annual well-adolescent visits, from February 1 to 28, 2019. Inductive qualitative textual analysis evaluated sexual history documentation as informative (containing clear indication of patient as sexually active or not) or noninformative and identified documentation subtypes. We examined patient and clinic characteristics by sexual history documentation type (informative or noninformative) and chlamydia screening status and documentation subtypes across clinic types using chi-square and Fisher’s exact tests. A multilevel logistic regression model considering clinic-specific random effects evaluated predictors of informative sexual history documentation. ResultsChart notes were examined for 1,062 patients across 31 unique clinics. Only 34.7% of chart notes were found to have informative sexual history documentation. Older patients (odds ratio: 1.51, 95% confidence interval: 0.99-2.31) and patients seen at clinics receiving U.S. Department of Health and Human Services Title-X funding (odds ratio: 11.05, 95% confidence interval: 1.34-90.86) had higher rates of informative documentation. The overall Chlamydia screening rate was 13.1%. ConclusionSexual history documentation varied widely across clinics, and the majority of chart notes were found to have noninformative documentation. Understanding and addressing barriers to informative sexual history documentation and comprehensive sexual health care is fundamental to improve adolescent sexual health outcomes, particularly given recently enacted federal electronic health record transparency policies.

857. Discussion and Initiation of HIV Pre-exposure Prophylaxis Were Rare Following Diagnoses of Sexually Transmitted Infections among Veterans

Abstract Background Healthcare encounters for the diagnosis and treatment of sexually transmitted infections (STIs) are common and represent a window of opportunity to discuss and initiate HIV pre-exposure prophylaxis (PrEP). Little is known about how frequently PrEP is discussed and initiated in association with encounters for STIs. Methods We conducted a retrospective cohort and nested case control study in the national Veterans Administration (VA) healthcare system to determine the frequency of PrEP discussion and initiation in association with clinical encounters for bacterial STIs (i.e. early syphilis, gonorrhea, and chlamydia). We used administrative data to identify patients with a first STI based on ICD 9 / 10 codes from January 2013–December 2018 , excluding patients with prior HIV diagnosis or PrEP use, or STI diagnosed in context of a visit to initiate PrEP (Figure 1). We used pharmacy data to determine the frequency of PrEP initiation within 90 days of the encounter for STI in this cohort. In the case control study, we matched 90 PrEP starters to 180 non-starters by day of STI diagnosis and reviewed chart notes from the STI diagnosis encounter to determine frequency of documentation of sexual history taking and PrEP discussions among subsequent PrEP initiators and non-initiators. Results We identified 23,312 patients with a first STI, of whom 90 (0.4%) started PrEP within 90 days. Adjusting for age, PrEP initiation was associated with urban residence (OR=5.0, 95Cl 1.8–13.4), White compared to Black race (OR=1.7, 95 Cl 1.1–2.8), and syphilis diagnosis (OR = 7.4, 95 Cl 4.7–11.6, table 1). Chart review revealed that discussion of PrEP was rare among people with STIs who did not subsequently start PrEP (1.1%, 95 CI 0.1–4.0, table 2). PrEP initiation was associated with documentation of any sexual history (80.0% of initiators vs. 51.0% of non-initiators, p &amp;lt; 0.01) and discussion of PrEP (52.2% vs. 1.1%, p &amp;lt; 0.01) during the initial STI diagnosis encounter. Figure 1. Study flow chart Table 1. Characteristics of patients with a first healthcare encounter with an STI diagnosis, by PrEP initiation within 90 days of encounter. N= 23,312 Table 2. Chart review findings from case control study. Ninety people who initiated PrEP (i.e., “cases”) were randomly matched to 180 who did not initiate PrEP (i.e., “controls”) by date of STI. Conclusion Discussion and initiation of PrEP were rare in association with healthcare encounters for STIs. Not all individuals with STIs will benefit from starting PrEP, but interventions are needed to improve low rates of sexual history-taking and discussion of PrEP during healthcare encounters for STIs.

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

PurposeSexually transmitted infections (STIs) are disproportionally prevalent in adolescents, and adolescents often present to the pediatric emergency department (PED) for STI care. Prior studies have found low rates of sexual history documentation and STI testing in the PED. However, these studies have had limited sample sizes because of the burden of manual chart review. We aimed to estimate the rate of sexual history documentation and identify factors associated with STI testing in a large cohort of adolescents using natural language processing (NLP). MethodsWe applied a validated NLP algorithm to all adolescent visits over a three-year period to the PED at a single large children's health care organization with a chief complaint potentially related to an STI. We utilized NLP to determine the prevalence of sexual history documentation in these patients. We applied logistic regression models to determine associations between sexual history documentation, patient demographic factors, and STI testing. ResultsOf the 1,987 patient encounters included, only 56% had a sexual history documented, and only 40% of all patients were tested for STIs. Patients were more likely to have a sexual history documented and to be tested for STIs if they were of non-Hispanic black race/ethnicity, were >15 years of age, and had nonprivate insurance. Patients with a sexual history documented were seven times more likely to have STI testing ordered. Of patients tested (n = 728), 25% were positive for an STI. ConclusionsDespite presenting to the PED with symptoms potentially related to an STI, many adolescents are not receiving recommended sexual health care. Rates of sexual history documentation and STI testing varied by demographic factors including race, age, and insurance status. Utilizing NLP technology allowed us to examine a larger sample size than previously documented in the adolescent sexual history and PED literature. This study highlights critical opportunities to improve sexual health provision and equity of care provided in the PED.

Unexpected Reason for Non-healing Oral Ulcers: Syphilis.

Syphilis is a sexually transmitted infectious disease caused by Treponema pallidum and characterized by a complex and variable clinical presentation. Cases of unexpected oral syphilis presenting as non-healing ulcers are uncommonly reported. We report 3 cases (one female and two males, aged 35, 35, and 56 years, respectively) in which patients presented with non-healing oral ulcers. Biopsies revealed surface ulceration and a significant neutrophilic infiltrate rather than the more conventional plasma cell infiltrate seen with most reported syphilis infections, potentially leading to an inaccurate diagnosis. Treponema pallidum immunohistochemistry highlighted spirochetes within the epithelium, with additional diagnostic confirmation by serum T. pallidum particle agglutination assay. Sexual history documentation by the clinician with nonspecific oral ulcers is paramount to aiding diagnosis and leading to proper management. Further, it is important to perform immunohistochemistry for T. pallidum in oral biopsies from non-healing ulcers, especially when clinical history raises the differential diagnosis or when other clinical manifestations may support this consideration.
