Evaluating the Proportion of Low-Value Blood Cultures Obtained in a Pediatric Emergency Department.

BACKGROUND: Existing literature suggests that for some pediatric conditions, blood cultures may be of low value in specific clinical circumstances. The goals of our study were to: 1) identify common pediatric illnesses and define criteria for low-value blood cultures in children aged from 91 days to 19 years, 2) apply these criteria retrospectively to identify the patients in our emergency department (ED) who had low-value blood cultures obtained, and 3) describe this cohort and assess the proportion of true bacteremia in low-value blood cultures. METHOD: The study team reviewed the literature and developed consensus criteria to identify conditions in which blood cultures were of low value for our study population. The criteria were applied retrospectively to well-appearing patients aged from 91 days to 19 years, without a central venous catheter, and evaluated in our ED with a peripheral blood culture from June 2018 to April 2020. Children admitted to the intensive care/hematology-oncology/cardiology/pulmonary units, those transferred from our ED to an outside facility, who transferred to our ED due to a positive blood culture from an outside facility, and repeat visits of a patient within 30 days from a previous visit were excluded from the study. After chart review, children with fever for 7 days or more, who were unvaccinated, immunosuppressed, had implanted devices, had a complex medical history, or had provider concerns for bacteremia/sepsis were excluded. RESULTS: The study population consisted of 1436 children. Children at risk for bacteremia (n = 718) were excluded. Four hundred twenty-four children had discharge diagnoses not included in our study. There were 294 (20.5%) patients who had low-value cultures per our study criteria. Nine children (9/294, 3.1%) had false-positive blood cultures, and three (3/294, 1.0%) had true-positive blood cultures. CONCLUSIONS: We identified a cohort of patients in our ED with blood cultures obtained when available literature indicates they were of low value.

Pediatric Emergency Physicians' Knowledge, Attitudes, and Behaviors Regarding Confidential Adolescent Care.

OBJECTIVES: More than 19 million adolescents seek care in the emergency department (ED) annually. We aimed to describe the knowledge, attitudes, and behaviors related to confidential adolescent care among pediatric ED physicians. METHODS: We conducted a cross-sectional questionnaire of US physician members of the Pediatric Emergency Medicine Collaborative Research Committee survey listserv. The 24-item questionnaire assessed familiarity with adolescent confidentiality laws, attitudes toward providing confidential care, frequency of discussing behavioral health topics confidentially, and factors influencing the decision to provide confidential care. We dichotomized Likert responses and used χ 2 to compare subgroups. RESULTS: Of 476 eligible physicians, 151 (32%) participated. Most (91. 4%) had completed pediatric emergency medicine fellowship. More participants reported familiarity with all sexual health-related laws compared with all mental health-related laws (64% vs 49%, P < 0.001). The median age at which participants thought it was important to begin routinely providing confidential care was 12 years; 9% thought confidential interviews should not be routinely conducted until older adolescence or at all. Their decision to provide confidential care was influenced by the following: chief complaint (97%), time (43%), language (24%), presence of family (23%) or friends (14%), and space (22%). CONCLUSIONS: Respondents reported moderate familiarity with adolescent confidentiality laws. Although they viewed confidential care as something they were comfortable providing, the likelihood of doing so varied. Barriers to confidential care were influenced by their assessment of adolescents' behavioral health risk, which may contribute to health inequity. Future efforts are needed to develop strategies that augment confidential ED care for adolescents.

Intranasal fentanyl and discharge from the emergency department among children with sickle cell disease and vaso-occlusive pain: A multicenter pediatric emergency medicine perspective.

Children with sickle cell disease (SCD) commonly experience vaso-occlusive pain episodes (VOE) due to sickling of erythrocytes, which often requires care in the emergency department. Our objective was to assess the use and impact of intranasal fentanyl for the treatment of children with SCD-VOE on discharge from the emergency department in a multicenter study. We conducted a cross-sectional study at 20 academic pediatric emergency departments in the United States and Canada. We used logistic regression to test bivariable and multivariable associations between the outcome of discharge from the emergency department and candidate variables theoretically associated with discharge. The study included 400 patients; 215 (54%) were female. The median age was 14.6 (interquartile range 9.8, 17.6) years. Nineteen percent (n = 75) received intranasal fentanyl in the emergency department. Children who received intranasal fentanyl had nearly nine-fold greater adjusted odds of discharge from the emergency department compared to those who did not (adjusted odds ratio 8.99, 95% CI 2.81-30.56, p < .001). The rapid onset of action and ease of delivery without intravenous access offered by intranasal fentanyl make it a feasible initial parenteral analgesic in the treatment of children with SCD presenting with VOE in the acute-care setting. Further study is needed to determine potential causality of the association between intranasal fentanyl and discharge from the emergency department observed in this multicenter study.

The Use of the Consolidated Framework for Implementation Research to Understand Facilitators and Barriers to Sexually Transmitted Infection Screening in Primary Care.

BACKGROUND: Adolescents bear a disproportionate burden of sexually transmitted infections (STIs) and the sequelae of delayed treatment, yet STI screening is infrequently performed in pediatric primary care clinics with many of those at-risk not administered testing. This study aims to understand contextual factors influencing STI screening and testing among adolescents in pediatric primary care. METHODS: We used the Consolidated Framework for Implementation Research (CFIR) as part of a stepwise approach to facilitate a deep understanding the pediatric primary care environment. We conducted semistructured interviews of physicians, nurses, and patient-parent dyads from 4 pediatric primary care practices in the St. Louis metropolitan area about STI screening practices and common concerns regarding STI screening. Qualitative analysis was conducted using a categorical coding technique informed by the CFIR followed by a thematic coding technique. RESULTS: We interviewed 23 physicians/nurses and 12 patient-parent dyads. Individual-level barriers to STI screening and testing included wide variability in clinicians' practice patterns and their perception of STI risk in the patient population. Structural barriers included a lack of capacity to perform testing in clinic and time constraints during patient visits. Confidentiality issues also created significant barriers to screening and testing on both individual and structural levels. Adopting confidential methods for testing and educating providers on patients' recommendations for STI testing were discussed as ways to potentially improve STI care in pediatric patients. CONCLUSIONS: Our use of the CFIR facilitated a systematic approach to identify gaps in STI care for adolescents and identified opportunities to close those gaps. An integrated, systematic approach that enhances patient confidentiality and improves clinicians' knowledge could address gaps in STI care in pediatric primary care settings.

Adolescent Substance Abuse Risk: A Comparison of Pediatric Emergency Care Applied Research Network Emergency Department Patients and 2 Nationally Representative Samples.

OBJECTIVES: The aim of this study was to understand the prevalence of alcohol and other substance use among teenagers in generalized samples. METHODS: This study compared the alcohol and other substance use of adolescents enrolled in a screening study across 16 Pediatric Emergency Care Applied Research Network emergency departments (EDs) (ASSESS) with those sampled in 2 nationally representative surveys, the Youth Risk Behavior Surveillance System (YRBSS) and the National Survey of Drug Use and Health (NSDUH). The analysis includes 3362 ASSESS participants and 11,142 YRBSS and 12,086 NSDUH respondents. RESULTS: The ASSESS patients had a similar profile to the NSDUH sample, with small differences in marijuana and cocaine use and age at first tobacco smoking and smoking within the last 30 days and higher use of snuff or chewing tobacco. The YRBSS participants had higher rates of using marijuana, snuff/chewing tobacco, methamphetamine, and hallucinogens and higher smoking rates compared with ASSESS and NSDUH. CONCLUSIONS: Adolescents visiting Pediatric Emergency Care Applied Research Network EDs have substantial rates of substance use, similar to other nationally representative studies on this topic, although not as high as a school-based survey. Future ED studies should continue to investigate adolescent substance use, including exploring optimal methods of survey administration.

Emergency Information Forms for Children With Medical Complexity: A Qualitative Study.

OBJECTIVES: Children with medical complexity (CMC) are at risk for poor outcomes during medical emergencies. Emergency information forms (EIFs) provide essential medical information for CMC during emergencies; however, they are not widely used. We sought to identify factors related to optimal care for CMC to inform development of EIFs for CMC. METHODS: We interviewed 26 stakeholders, including parents of CMC, healthcare providers, health information technology, and privacy compliance experts. We inquired about barriers and facilitators to emergency care of CMC, as well as the desired content, structure, ownership, and maintenance of an EIF. Audio recordings were transcribed and analyzed inductively for common themes using thematic analysis techniques. RESULTS: Providers identified problems with documentation and poor caregiver understanding as major barriers to care. Parents reported poor provider understanding of their child's condition as a barrier. All groups reported that summary documents facilitate quality care. Recommended content included demographic/contact information, medical history, medications, allergies, advance directives, information about the patient's disease, and an action plan for anticipated emergencies. Twenty-three participants indicated a preference for electronic EIFs; 19 preferred a Web-based EIF that syncs with the medical record, with paper or portable electronic copies. Although 13 participants thought that EIFs should be patient owned to ensure availability during emergencies, 19 expected medical providers to create and update EIFs. CONCLUSIONS: Stakeholders interviewed reported a preference for Web-based, sync-capable EIFs with portable copies. Emergency information forms could be maintained by providers but owned by patients to optimize emergency care and align with the concept of the medical home.

Normal saline bolus use in pediatric emergency departments is associated with poorer pain control in children with sickle cell anemia and vaso-occlusive pain.

Vaso-occlusive pain events (VOE) are the leading cause of emergency department (ED) visits in sickle cell anemia (SCA). This study assessed the variability in use of intravenous fluids (IVFs), and the association of normal saline bolus (NSB), on pain and other clinical outcomes in children with SCA, presenting to pediatric emergency departments (PED) with VOE. Four-hundred charts of children age 3-21 years with SCA/VOE receiving parenteral opioids at 20 high-volume PEDs were evaluated in a retrospective study. Data on type and amount of IVFs used were collected. Patients were divided into two groups: those who received NSB and those who did not. The association of NSB use on change in pain scores and admission rates was evaluated. Among 400 children studied, 261 (65%) received a NSB. Mean age was 13.8 ± 4.9 years; 46% were male; 92% had hemoglobin-SS. The IVFs (bolus and/or maintenance) were used in 84% of patients. Eight different types of IVFs were utilized and IVF volume administered varied widely. Mean triage pain scores were similar between groups, but improvement in pain scores from presentation-to-ED-disposition was smaller in the NSB group (2.2 vs 3.0, P = .03), while admission rates were higher (71% vs 59%, P = .01). Use of NSB remained associated with poorer final pain scores and worse change in pain scores in our multivariable model. In conclusion, wide variations in practice utilizing IVFs are common. NSB is given to >50% of children with SCA/VOE, but is associated with poorer pain control; a controlled prospective trial is needed to determine causality.

Characteristics of youth agreeing to electronic sexually transmitted infection risk assessment in the emergency department.

OBJECTIVES: Adolescents and young adults are at high risk for sexually transmitted infections (STIs). We previously reported an increase in STI testing of adolescents in our ED by obtaining a sexual history using an Audio-enhanced Computer-Assisted Self-Interview (ACASI). We now examine associations among demographics, sexual behaviour, chief complaint and willingness to be tested. METHODS: This was a prospective study conducted in a paediatric ED between April and December 2011. After triage, eligible patients between 15 and 21 years presenting with non-life-threatening conditions were asked to participate in the study. Consenting participants used an ACASI to provide their demographic data and answer questions about their sexual history and willingness to be tested. Our primary outcome was the association of demographics, chief complaint and ACASI recommendation with the participant's willingness to be tested. RESULTS: We approached 1337 patients, of whom 800 (59%) enrolled and completed the ACASI. Eleven who did not answer questions related to their sexual history were excluded from analysis. Of 789 participants, 461 (58.4%) were female and median age was 16.9 years (IQR 16.0-17.8); 509 (64.5%) endorsed a history of anal, oral and/or vaginal intercourse. Disclosing a sexual history and willingness to be tested did not differ significantly by gender. 131 (16.6%) had a chief complaint potentially referable to an STI; among the 658 participants with non-STI-related complaints, 412 (62.6%) were sexually active, many of whom disclosed risky behaviours, including multiple partners (46.4%) and inconsistent condom use (43.7%). The ACASI identified 419 patients as needing immediate STI testing; the majority (81%) did not have a chief complaint potentially related to STIs. 697 (88.3%) participants were willing to receive STI testing. Most (94.6%) of the patients with STI-related complaints were willing to be tested, and 92.1% of patients with a recommendation for immediate testing by the ACASI indicated a willingness to be tested. CONCLUSIONS: Adolescents were willing to disclose sexual activity via electronic questionnaires and were willing to receive STI testing, even when their chief complaint was not STI related. The ACASI facilitated identification of adolescent ED patients needing STI testing regardless of chief complaint.

Impact of an Institutional Guideline on the Care of Neonates at Risk for Herpes Simplex Virus in the Emergency Department.

BACKGROUND AND OBJECTIVES: Herpes simplex virus (HSV) is rare in neonates but carries significant morbidity and mortality in that group. Emergency department (ED) clinicians have little guidance to decide when to test for HSV and give acyclovir. We created an institutional guideline to provide guidance in patients younger than 6 weeks. Our objective was to evaluate whether guideline implementation affected the ED's decision to test for HSV, and ED use of HSV polymerase chain reactions (PCRs) and acyclovir. METHODS: We reviewed charts for patients 1 year before implementation and 1 year after implementation of our guideline. Inclusion criteria were younger than 60 days, admitted through the ED, symptom onset younger than 6 weeks, and any one of the following criteria: (1) ED blood culture obtained, (2) ED or inpatient HSV PCR obtained, and (3) ED or inpatient acyclovir treatment. Premature patients and transfer patients were excluded. We compared whether the decision to initiate HSV testing, ED use of HSV PCRs, serum alanine aminotransferase, and acyclovir use changed post-guideline implementation. RESULTS: We reviewed 173 charts pre-implementation and 129 post-implementation. We found a significant decrease in ED testing for HSV among patients who did not meet guideline criteria (P < 0.01). We saw an improvement in the use of alanine aminotransferase among patients who met criteria for testing (P = 0.02), but no change in the use of HSV PCRs or acyclovir use among tested patients. CONCLUSIONS: Guideline implementation reduced HSV evaluations in low-risk patients, but did not improve test utilization or acyclovir administration among those tested. Additional work is needed to improve guideline utilization.

Initial Presentation of Neonatal Herpes Simplex Virus Infection.

OBJECTIVE: To inform the decision to test and empirically treat for herpes simplex virus (HSV) by describing the initial clinical presentation and laboratory findings of infants with a confirmed diagnosis of neonatal HSV. STUDY DESIGN: This is a retrospective case series performed at 2 pediatric tertiary care centers. Infants who developed symptoms prior to 42 days of age with laboratory confirmed HSV from 2002 through 2012 were included. We excluded infants <34 weeks gestation, those who developed illness before discharge from their birth hospital, and those who developed symptoms after 42 days of age. RESULTS: We identified 49 infants with HSV meeting these criteria. Most infants (43/49, 88%) came to medical attention at ≤28 days. Of 49 infants, 22 (45%) had disseminated, 16 (33%) central nervous system, and 10 (20%) skin, eye, mouth HSV disease. Eight infants (16%) had nonspecific presentations without the classic signs of seizure, vesicular rash, or critical illness (intensive care admission). All infants with nonspecific presentation were ≤14 days, had cerebrospinal fluid pleocytosis, or both. CONCLUSIONS: The majority of infants with HSV (84%) presented with seizure, vesicular rash, or critical illness. A subset of patients (16%) lacked classic signs at hospitalization; most manifested signs suggestive of HSV within 24 hours. Further studies are needed to validate the risk factors identified in this study including age <14 days and cerebrospinal fluid pleocytosis at presentation.

Computerized self-interviews improve Chlamydia and gonorrhea testing among youth in the emergency department.

STUDY OBJECTIVE: National guidelines recommend annual Chlamydia trachomatis and Neisseria gonorrhoeae screening for sexually active youth at risk for infection. These infections have serious sequelae in women if untreated, and methods to improve testing are needed. We hypothesize that an electronic method of identifying at-risk youth will significantly increase testing for these sexually transmitted infections during emergency department (ED) visits. METHODS: We developed an audio-enhanced computer-assisted self-interview (ACASI) to obtain sexual histories from ED patients and an embedded decision tree to create a sexually transmitted infection testing recommendation. ED health care providers were prompted by the electronic medical record to review the participant answers and testing recommendations, and to offer testing to at-risk youth. Patients aged 15 to 21 years and visiting the St. Louis Children's Hospital ED, regardless of complaint, were eligible for participation. RESULTS: Sexually transmitted infection testing among all 15- to 21-year-old ED patients increased from 9.3% in the 3 months before the ACASI to 17.8% during the 8-month period the ACASI was available and diminished to 12.4% in the 3 months after ACASI withdrawal (P<.001). During the ACASI period, we approached 51.4% of eligible patients and enrolled 59.8% (800/1,337) of those approached. Among ACASI participants, 52.4% (419/800) received a recommendation to receive sexually transmitted infection testing. Of these patients, 52.7% (221/419) received testing in the ED and 18.1% (40/221) of those tested had positive results for chlamydia or gonorrhea, 55% of whom (22/40) had chief complaints unrelated to sexually transmitted infections. Most participants (89%) rated the ACASI easy to use. CONCLUSION: Sexually transmitted infection testing in the ED significantly increased during ACASI use and diminished after withdrawal. The ACASI was well accepted by youth and holds promise for enhancing sexually transmitted infection testing in the ED.

PECARN prediction rule for cervical spine imaging of children presenting to the emergency department with blunt trauma: a multicentre prospective observational study.

BACKGROUND: Cervical spine injuries in children are uncommon but potentially devastating; however, indiscriminate neck imaging after trauma unnecessarily exposes children to ionising radiation. The aim of this study was to derive and validate a paediatric clinical prediction rule that can be incorporated into an algorithm to guide radiographic screening for cervical spine injury among children in the emergency department. METHODS: In this prospective observational cohort study, we screened children aged 0-17 years presenting with known or suspected blunt trauma at 18 specialised children's emergency departments in hospitals in the USA affiliated with the Pediatric Emergency Care Applied Research Network (PECARN). Injured children were eligible for enrolment into derivation or validation cohorts by fulfilling one of the following criteria: transported from the scene of injury to the emergency department by emergency medical services; evaluated by a trauma team; and undergone neck imaging for concern for cervical spine injury either at or before arriving at the PECARN-affiliated emergency department. Children presenting with solely penetrating trauma were excluded. Before viewing an enrolled child's neck imaging results, the attending emergency department clinician completed a clinical examination and prospectively documented cervical spine injury risk factors in an electronic questionnaire. Cervical spine injuries were determined by imaging reports and telephone follow-up with guardians within 21-28 days of the emergency room encounter, and cervical spine injury was confirmed by a paediatric neurosurgeon. Factors associated with a high risk of cervical spine injury (>10%) were identified by bivariable Poisson regression with robust error estimates, and factors associated with non-negligible risk were identified by classification and regression tree (CART) analysis. Variables were combined in the cervical spine injury prediction rule. The primary outcome of interest was cervical spine injury within 28 days of initial trauma warranting inpatient observation or surgical intervention. Rule performance measures were calculated for both derivation and validation cohorts. A clinical care algorithm for determining which risk factors warrant radiographic screening for cervical spine injury after blunt trauma was applied to the study population to estimate the potential effect on reducing CT and x-ray use in the paediatric emergency department. This study is registered with ClinicalTrials.gov, NCT05049330. FINDINGS: Nine emergency departments participated in the derivation cohort, and nine participated in the validation cohort. In total, 22 430 children presenting with known or suspected blunt trauma were enrolled (11 857 children in the derivation cohort; 10 573 in the validation cohort). 433 (1·9%) of the total population had confirmed cervical spine injuries. The following factors were associated with a high risk of cervical spine injury: altered mental status (Glasgow Coma Scale [GCS] score of 3-8 or unresponsive on the Alert, Verbal, Pain, Unresponsive scale [AVPU] of consciousness); abnormal airway, breathing, or circulation findings; and focal neurological deficits including paresthesia, numbness, or weakness. Of 928 in the derivation cohort presenting with at least one of these risk factors, 118 (12·7%) had cervical spine injury (risk ratio 8·9 [95% CI 7·1-11·2]). The following factors were associated with non-negligible risk of cervical spine injury by CART analysis: neck pain; altered mental status (GCS score of 9-14; verbal or pain on the AVPU; or other signs of altered mental status); substantial head injury; substantial torso injury; and midline neck tenderness. The high-risk and CART-derived factors combined and applied to the validation cohort performed with 94·3% (95% CI 90·7-97·9) sensitivity, 60·4% (59·4-61·3) specificity, and 99·9% (99·8-100·0) negative predictive value. Had the algorithm been applied to all participants to guide the use of imaging, we estimated the number of children having CT might have decreased from 3856 (17·2%) to 1549 (6·9%) of 22 430 children without increasing the number of children getting plain x-rays. INTERPRETATION: Incorporated into a clinical algorithm, the cervical spine injury prediction rule showed strong potential for aiding clinicians in determining which children arriving in the emergency department after blunt trauma should undergo radiographic neck imaging for potential cervical spine injury. Implementation of the clinical algorithm could decrease use of unnecessary radiographic testing in the emergency department and eliminate high-risk radiation exposure. Future work should validate the prediction rule and care algorithm in more general settings such as community emergency departments.

Adapting an Electronic STI Risk Assessment Program for Use in Pediatric Primary Care.

OBJECTIVES: Sexually transmitted infections (STIs) are an ongoing public health issue in adolescents. the Centers for Disease Control and Prevention and American Academy of Pediatrics have and continue to recommend STI screening in at-risk adolescents, however screening and testing continues to lag behind the need. We previously designed and implemented an electronic risk assessment tool to support STI testing in our pediatric emergency department. Pediatric primary care clinics may be better positioned for STI risk assessments, as they can offer greater privacy and confidentiality, a lower stress environment, and greater opportunity for longitudinal care. STI risk assessment and testing continues to be a challenge in this setting. The goal of this work was to evaluate the usability of our electronic tool to support adaptation and implementation in pediatric primary care practices. METHODS: We conducted qualitative interviews of pediatricians, clinic staff, and adolescents from 4 pediatric practices as part of a study whose goal is to ultimately implement STI screening in pediatric primary care. The goal of the interviews were (1) to understand contextual factors related to STI screening in primary care, which we have reported previously, and (2) to obtain feedback on our electronic platform, the questionnaire content, and their perspective on implementing it in primary care settings, which we report here. We received quantitative feedback using the System Usability Scale (SUS). The SUS is a validated, reliable tool to measure the usability of hardware, software, websites, and applications. SUS scores range from a score of 0 to 100, with a score of 68 or higher indicating above average usability. We additionally obtained qualitative feedback via interviews and used inductive analysis to identify common themes. RESULTS: We recruited 14 physicians, 9 clinic staff, and 12 adolescents. Participants rated the tool highly using the SUS, with a median score of 92.5 (threshold for average usability is 68) and an interquartile range of 82.5 to 100. Thematically, all participants perceived a need for such a screening program and indicated the format would encourage more honest responses on the topic adolescents. We used these results to modify the questionnaire prior to implementing it into participating practices. CONCLUSION: We demonstrated that our electronic STI risk assessment tool had a high level of usability and could be adapted for use in pediatric primary care.

Impact of SARS-CoV-2 Infection on the Association Between Laboratory Tests and Severe Outcomes Among Hospitalized Children.

Background: To assist clinicians with identifying children at risk of severe outcomes, we assessed the association between laboratory findings and severe outcomes among severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-infected children and determined if SARS-CoV-2 test result status modified the associations. Methods: We conducted a cross-sectional analysis of participants tested for SARS-CoV-2 infection in 41 pediatric emergency departments in 10 countries. Participants were hospitalized, had laboratory testing performed, and completed 14-day follow-up. The primary objective was to assess the associations between laboratory findings and severe outcomes. The secondary objective was to determine if the SARS-CoV-2 test result modified the associations. Results: We included 1817 participants; 522 (28.7%) SARS-CoV-2 test-positive and 1295 (71.3%) test-negative. Seventy-five (14.4%) test-positive and 174 (13.4%) test-negative children experienced severe outcomes. In regression analysis, we found that among SARS-CoV-2-positive children, procalcitonin ≥0.5 ng/mL (adjusted odds ratio [aOR], 9.14; 95% CI, 2.90-28.80), ferritin >500 ng/mL (aOR, 7.95; 95% CI, 1.89-33.44), D-dimer ≥1500 ng/mL (aOR, 4.57; 95% CI, 1.12-18.68), serum glucose ≥120 mg/dL (aOR, 2.01; 95% CI, 1.06-3.81), lymphocyte count <1.0 × 109/L (aOR, 3.21; 95% CI, 1.34-7.69), and platelet count <150 × 109/L (aOR, 2.82; 95% CI, 1.31-6.07) were associated with severe outcomes. Evaluation of the interaction term revealed that a positive SARS-CoV-2 result increased the associations with severe outcomes for elevated procalcitonin, C-reactive protein (CRP), D-dimer, and for reduced lymphocyte and platelet counts. Conclusions: Specific laboratory parameters are associated with severe outcomes in SARS-CoV-2-infected children, and elevated serum procalcitonin, CRP, and D-dimer and low absolute lymphocyte and platelet counts were more strongly associated with severe outcomes in children testing positive compared with those testing negative.

Impact of risk-based sexually transmitted infection screening in the emergency department.

OBJECTIVES: Sexually transmitted infections (STIs), including chlamydia, gonorrhea, and human immunodeficiency virus (HIV) pose a significant health burden in adolescents. Many adolescents receiving care in the emergency department (ED) are in need of testing, regardless of their chief complaint. Our objective was to determine whether an electronic, risk-based STI screening program in our ED was associated with an increase in STI testing among at-risk adolescents. METHODS: We conducted a retrospective cohort analysis of patient outcomes in our pediatric ED after integrating an Audio-enhanced Computer-Assisted Self-Interview (ACASI) as standard of care. It obtained a focused sexual history and generated STI testing recommendations. Patient answers and testing recommendations were integrated in real-time into the electronic health record. Patients who tested positive received treatment according to our standard-of-care practices. All patients 15-21 years of age were asked to complete this on an opt-out basis, regardless of the reason for their ED visit. Exclusions included those unable to independently use a tablet, severe illness, sexual assault, or non-English speaking. Our primary outcome was to describe STI-testing recommendations and test results among ACASI participants. We also compared STI testing between ACASI participants and those who were eligible but did not use it. RESULTS: In the first 13 months, 28.9% (1788/6194) of eligible adolescents completed the ACASI and 44.2% (321/790) accepted recommended STI testing. The mean age of participants was 16.6 ± 1.3 years, with 65.4% (1169) being female. Gonorrhea/chlamydia testing was significantly higher among participants vs. non-participants (20.1% [359/1788] vs 4.8% [212/4406]; p < 0.0001). The proportion of positive STI tests was similar between the two groups: 24.8% (89/359) vs. 24.5% (52/212; p = 0.94) were positive for chlamydia and/or gonorrhea, while 0.6% (2/354) participants vs. 0% non-participants (p > 0.99) were positive for HIV. Among participants whose chief complaints were unlikely to be related to STIs but accepted recommended testing, 20.9% (37/177) were positive for gonorrhea or chlamydia. CONCLUSIONS: Our program facilitated STI testing in the ED and identified many adolescents with STIs, even when their ED complaint was for unrelated reasons. More rigorous implementation is needed to determine the impact of deployment of ACASI to all eligible adolescents and addressing barriers to accepting STI testing recommendations.

Post-COVID-19 Conditions Among Children 90 Days After SARS-CoV-2 Infection.

Importance: Little is known about the risk factors for, and the risk of, developing post-COVID-19 conditions (PCCs) among children. Objectives: To estimate the proportion of SARS-CoV-2-positive children with PCCs 90 days after a positive test result, to compare this proportion with SARS-CoV-2-negative children, and to assess factors associated with PCCs. Design, Setting, and Participants: This prospective cohort study, conducted in 36 emergency departments (EDs) in 8 countries between March 7, 2020, and January 20, 2021, included 1884 SARS-CoV-2-positive children who completed 90-day follow-up; 1686 of these children were frequency matched by hospitalization status, country, and recruitment date with 1701 SARS-CoV-2-negative controls. Exposure: SARS-CoV-2 detected via nucleic acid testing. Main Outcomes and Measures: Post-COVID-19 conditions, defined as any persistent, new, or recurrent health problems reported in the 90-day follow-up survey. Results: Of 8642 enrolled children, 2368 (27.4%) were SARS-CoV-2 positive, among whom 2365 (99.9%) had index ED visit disposition data available; among the 1884 children (79.7%) who completed follow-up, the median age was 3 years (IQR, 0-10 years) and 994 (52.8%) were boys. A total of 110 SARS-CoV-2-positive children (5.8%; 95% CI, 4.8%-7.0%) reported PCCs, including 44 of 447 children (9.8%; 95% CI, 7.4%-13.0%) hospitalized during the acute illness and 66 of 1437 children (4.6%; 95% CI, 3.6%-5.8%) not hospitalized during the acute illness (difference, 5.3%; 95% CI, 2.5%-8.5%). Among SARS-CoV-2-positive children, the most common symptom was fatigue or weakness (21 [1.1%]). Characteristics associated with reporting at least 1 PCC at 90 days included being hospitalized 48 hours or more compared with no hospitalization (adjusted odds ratio [aOR], 2.67 [95% CI, 1.63-4.38]); having 4 or more symptoms reported at the index ED visit compared with 1 to 3 symptoms (4-6 symptoms: aOR, 2.35 [95% CI, 1.28-4.31]; ≥7 symptoms: aOR, 4.59 [95% CI, 2.50-8.44]); and being 14 years of age or older compared with younger than 1 year (aOR, 2.67 [95% CI, 1.43-4.99]). SARS-CoV-2-positive children were more likely to report PCCs at 90 days compared with those who tested negative, both among those who were not hospitalized (55 of 1295 [4.2%; 95% CI, 3.2%-5.5%] vs 35 of 1321 [2.7%; 95% CI, 1.9%-3.7%]; difference, 1.6% [95% CI, 0.2%-3.0%]) and those who were hospitalized (40 of 391 [10.2%; 95% CI, 7.4%-13.7%] vs 19 of 380 [5.0%; 95% CI, 3.0%-7.7%]; difference, 5.2% [95% CI, 1.5%-9.1%]). In addition, SARS-CoV-2 positivity was associated with reporting PCCs 90 days after the index ED visit (aOR, 1.63 [95% CI, 1.14-2.35]), specifically systemic health problems (eg, fatigue, weakness, fever; aOR, 2.44 [95% CI, 1.19-5.00]). Conclusions and Relevance: In this cohort study, SARS-CoV-2 infection was associated with reporting PCCs at 90 days in children. Guidance and follow-up are particularly necessary for hospitalized children who have numerous acute symptoms and are older.

Outcomes of SARS-CoV-2-Positive Youths Tested in Emergency Departments: The Global PERN-COVID-19 Study.

Importance: Severe outcomes among youths with SARS-CoV-2 infections are poorly characterized. Objective: To estimate the proportion of children with severe outcomes within 14 days of testing positive for SARS-CoV-2 in an emergency department (ED). Design, Setting, and Participants: This prospective cohort study with 14-day follow-up enrolled participants between March 2020 and June 2021. Participants were youths aged younger than 18 years who were tested for SARS-CoV-2 infection at one of 41 EDs across 10 countries including Argentina, Australia, Canada, Costa Rica, Italy, New Zealand, Paraguay, Singapore, Spain, and the United States. Statistical analysis was performed from September to October 2021. Exposures: Acute SARS-CoV-2 infection was determined by nucleic acid (eg, polymerase chain reaction) testing. Main Outcomes and Measures: Severe outcomes, a composite measure defined as intensive interventions during hospitalization (eg, inotropic support, positive pressure ventilation), diagnoses indicating severe organ impairment, or death. Results: Among 3222 enrolled youths who tested positive for SARS-CoV-2 infection, 3221 (>99.9%) had index visit outcome data available, 2007 (62.3%) were from the United States, 1694 (52.6%) were male, and 484 (15.0%) had a self-reported chronic illness; the median (IQR) age was 3 (0-10) years. After 14 days of follow-up, 735 children (22.8% [95% CI, 21.4%-24.3%]) were hospitalized, 107 (3.3% [95% CI, 2.7%-4.0%]) had severe outcomes, and 4 children (0.12% [95% CI, 0.03%-0.32%]) died. Characteristics associated with severe outcomes included being aged 5 to 18 years (age 5 to <10 years vs <1 year: odds ratio [OR], 1.60 [95% CI, 1.09-2.34]; age 10 to <18 years vs <1 year: OR, 2.39 [95% CI 1.38-4.14]), having a self-reported chronic illness (OR, 2.34 [95% CI, 1.59-3.44]), prior episode of pneumonia (OR, 3.15 [95% CI, 1.83-5.42]), symptoms starting 4 to 7 days prior to seeking ED care (vs starting 0-3 days before seeking care: OR, 2.22 [95% CI, 1.29-3.82]), and country (eg, Canada vs US: OR, 0.11 [95% CI, 0.05-0.23]; Costa Rica vs US: OR, 1.76 [95% CI, 1.05-2.96]; Spain vs US: OR, 0.51 [95% CI, 0.27-0.98]). Among a subgroup of 2510 participants discharged home from the ED after initial testing and who had complete follow-up, 50 (2.0%; 95% CI, 1.5%-2.6%) were eventually hospitalized and 12 (0.5%; 95% CI, 0.3%-0.8%) had severe outcomes. Compared with hospitalized SARS-CoV-2-negative youths, the risk of severe outcomes was higher among hospitalized SARS-CoV-2-positive youths (risk difference, 3.9%; 95% CI, 1.1%-6.9%). Conclusions and Relevance: In this study, approximately 3% of SARS-CoV-2-positive youths tested in EDs experienced severe outcomes within 2 weeks of their ED visit. Among children discharged home from the ED, the risk was much lower. Risk factors such as age, underlying chronic illness, and symptom duration may be useful to consider when making clinical care decisions.

The use of incentive spirometry in pediatric patients with sickle cell disease to reduce the incidence of acute chest syndrome.

INTRODUCTION: To determine if incentive spirometry (IS) in pediatric patients admitted with sickle cell disease for nonrespiratory complaints will decrease acute chest syndrome (ACS). METHODS: This was an Institutional Review Board-approved before-after 2-year retrospective cohort study evaluating an evidence-based guideline (EBG) initiating mandatory IS in admitted pediatric sickle cell patients from a tertiary children's emergency center. Student t testing and χ² analysis were performed. RESULTS: There were 1551 patient visits. About 258 visits were enrolled in the pre-EBG year, and 230 in the EBG year. Between year characteristics were similar. The EBG year reported higher use of hydroxyurea (P<0.01), analgesics (P=0.02), and chest pain (P=0.03). Sixty-seven patients (25.9%) in the pre-EBG year received transfusions versus 51 (22.5%) in the EBG year (NS). Twenty-five (9.6%) of the pre-EBG patients received blood for ACS versus 14 (6.1%) in the EBG group (absolute risk reduction: 3.5%, 95% confidence interval: -1-8.4%). Subgroup analysis revealed that patients who presented with back pain experienced a significant decrease in the development of ACS in the EBG year (P=0.04, absolute risk reduction: 14%, 95% confidence interval: 1-28%, number needed to treat: 8). CONCLUSION: Mandatory IS for sickle cell disease patients admitted without respiratory complaints reduces transfusions and ACS, particularly for those presenting with back pain.

Prehospital Factors Associated With Cervical Spine Injury in Pediatric Blunt Trauma Patients.

BACKGROUND: The risk for cervical spine injury (CSI) must be assessed in children who sustain blunt trauma. The Pediatric Emergency Care Applied Research Network (PECARN) retrospectively derived CSI model identifies CSI risk in children based on emergency department (ED) provider observations. The objective of this pilot study was to determine the univariate association of emergency medical services (EMS) provider-observed historical, mechanistic, and physical examination factors with CSI in injured children. Secondarily, we assessed the performance of the previously identified eight PECARN CSI risk factors (PECARN model) based exclusively on EMS provider observation. METHODS: We conducted a four-center, prospective observational study of children 0 to 17 years old who were transported by EMS after blunt trauma and underwent spinal motion restriction or trauma team activation in the ED. In the ED, EMS providers recorded their observations for a priori determined CSI risk factors. CSIs were classified by reviewing imaging, consultations, and/or telephone follow-up. We calculated bivariable relative risks and test characteristics for the PECARN model based solely on EMS provider observations. RESULTS: Of 1,372 enrolled children, 25 (1.8%) had CSIs. Of the a priori determined CSI risk factors, seven factors had bivariable associations with CSIs: axial load, altered mental status, signs of basilar skull fracture, substantial torso injury, substantial thoracic injury, respiratory distress, and decreased oxygen saturation. The PECARN model (high-risk motor vehicle collision, diving mechanism, predisposing condition, neck pain, decreased neck mobility, altered mental status, neurologic deficits, and/or substantial torso injury) exhibited the following test characteristics when based on EMS provider observations: sensitivity = 96.0% (95% confidence interval [CI] = 88.3% to 100.0%); negative predictive value = 99.8% (95% CI = 99.4% to 100.0%); specificity = 38.5% (95% CI = 35.9% to 41.1%); and positive predictive value = 2.8% (95% CI = 1.7% to 3.9%). CONCLUSION: EMS providers can identify risk factors associated with CSI in injured children who experience blunt trauma. These risk factors may be considered for inclusion in a pediatric CSI decision rule specific to the prehospital setting.
