Risk factors for Recurrent Clostridioides Difficile Infection in Children.

OBJECTIVE: The aims of this study were to determine the epidemiologic and treatment factors associated with recurrent C. difficile infection in children. METHODS: We conducted a 13-year retrospective review of pediatric C. difficile infections at our institution focusing on the epidemiologic, clinical, and treatment factors associated with recurrent disease. Repeat episodes occurring between 4 weeks and 2 months after initial infection were defined as early recurrences, whereas repeat episodes between 2 and 12 months after initial infection were defined as late recurrences. RESULTS: We identified 303 children with C. difficile infection. Recurrent infections were limited to children with chronic conditions, affecting 27.4% (68 of 248) of this cohort. Early and late recurrences occurred in 36.8 and 63.2% of children, respectively. Among children with a chronic condition, female sex and initial use of metronidazole (as opposed to vancomycin) were associated with recurrent disease in bivariate and multivariate analyses. Overall, there was a high treatment failure rate (34 of 102, 33.3%) once children had developed recurrent disease. CONCLUSIONS: Findings from this study demonstrate the importance of underlying chronic conditions in the development of recurrent C. difficile disease and the shortcomings of current treatment options for recurrent cases. Additionally, our findings indicate that initial treatment selection may impact the likelihood of future disease, with metronidazole usage being associated with higher recurrence rates than vancomycin. These findings highlight the need for additional studies to better understand the implications of C. difficile treatment strategies.

Venous thromboembolism prophylaxis practices for patients with sickle cell disease prior to and during the COVID-19 pandemic.

Patients with sickle cell disease (SCD) are predisposed to a hypercoagulable state due to alterations in the coagulation system. Despite concern for the development of venous thromboembolism (VTE) in this population, there are no standardized guidelines for routine thromboprophylaxis. The objective of this study was to assess thromboprophylaxis practices of adult and pediatric treaters of SCD before and during the coronavirus disease of 2019 (COVID-19) pandemic. A cross-sectional electronic survey was distributed to pediatric and adult hematology oncology practitioners through seven SCD-specific interest groups between May 29, 2020, and July 13, 2020. Of 93 total responses, 14% ( N  = 13) reported they only treat patients more than 21 years old; 38.7% ( N  = 36) only treat patients 0-21 years old and 47.3% ( N  = 44) reported they treat both. Our study showed that before the COVID-19 pandemic, 96% of adult practitioners would recommend pharmacologic thromboprophylaxis, mechanical thromboprophylaxis or both for hospitalized adults with thromboprophylaxis, but only 76% of pediatric treaters would recommend any thromboprophylaxis in hospitalized children ( P  < 0.0001), with 24% of pediatric treaters choosing no thromboprophylaxis at all. During the COVID-19 pandemic, pharmacologic thromboprophylaxis specifically was recommended for adults by 94% of treaters and for pediatric patients by 76% of treaters. These findings suggest that despite the lack of evidence-based thromboprophylaxis guidelines in adults and children with thromboprophylaxis, subspecialty treaters routinely provide pharmacologic thromboprophylaxis in their adult patients and will modify their practice in pediatric patients who are considered at a high risk for VTE.

Associating a standardized reporting tool for chest radiographs with clinical complications in pediatric acute chest syndrome.

BACKGROUND: Acute chest syndrome (ACS) is an important cause of morbidity in sickle cell disease (SCD). A standardized tool for reporting chest radiographs in pediatric SCD patients did not previously exist. OBJECTIVE: To analyze the interobserver agreement among pediatric radiologists' interpretations for pediatric ACS chest radiographs utilizing a standardized reporting tool. We also explored the association of radiographic findings with ACS complications. METHODS: This was a retrospective cohort study of pediatric ACS admissions from a single institution in 2019. ICD-10 codes identified 127 ACS admissions. Two radiologists independently interpreted the chest radiographs utilizing a standardized reporting tool, a third radiologist adjudicated discrepancies, and κ analysis assessed interobserver agreement. Clinical outcomes were correlated with chest radiograph findings utilizing Pearsons' χ2 , t tests, and Mann-Whitney U tests. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. RESULTS: Interobserver agreement was moderate to near-perfect across variables, with κ analysis showing near-perfect agreement for opacity reported in the right upper lobe (0.84), substantial agreement for right lower lobe (0.63), and vertebral bony changes (0.72), with moderate agreement for all other reported variables. On the initial chest radiograph, an opacity located in the left lower lobe (LLL) correlated with pediatric intensive care unit transfer (p = .03). Pleural effusion on the initial chest radiograph had a 3.98 OR (95% CI: 1.35-11.74) of requiring blood products and a 10.67 OR (95% CI: 3.62-31.39) for noninvasive ventilation. CONCLUSION: The standardized reporting tool showed moderate to near-perfect agreement between radiologists. LLL opacity, and pleural effusion were associated with increased risk of ACS complications.

Get SMART: Teaching Pediatric Residents the 2020 Focused Asthma Updates' Recommendations for Symptom-Based Medication Increases.

Introduction: The 2020 Focused Asthma Updates introduced a paradigm shift in the treatment of asthma that includes symptom-based adjustments to outpatient asthma treatment that vary by age and severity. The length and complexity of the updates have made them challenging to adopt. Methods: We implemented an educational session among pediatric residents to increase their familiarity with, comprehension of, and plans to adopt two evidence-based recommendations introduced in the 2020 Updates for symptom-based therapy. Facilitators led groups of four to six pediatric residents in cased-based discussions during a 30-minute, ambulatory care-based session. One week prior, participants and facilitators received synopses of the 2007 Guidelines for the Diagnosis and Management of Asthma and the 2020 Updates. Facilitators also received a guide and scripts explaining new concepts, providing supporting data, and highlighting learning objectives. Retrospective pre/post surveys assessed participants' familiarity with, comprehension of, and planned adoption of recommendations for intermittent steroids and single maintenance and reliever therapy (SMART) before and after the conference. The surveys also assessed prior exposure to the 2020 Updates and reflections on the educational session. Results: There were 26 participants. Ratings of familiarity, comprehension, and adoption plans regarding the recommendations significantly improved (ps < .001, Wilcoxon signed rank test). The case-based approach was well received, and the material was deemed relevant. Discussion: This educational session significantly increased pediatric residents' familiarity with, comprehension of, and plans to adopt two new evidence-based treatments. Dissemination of this educational session may improve outpatient asthma management.

Childhood asthma in the Bronx, NY; the impact of pollutants on length of hospital stay.

OBJECTIVE: The length of hospital stay (LOS) is a proxy of asthma exacerbation severity and healthcare cost. The study aims to estimate the effect of ambient air pollution on pediatric asthma LOS in the Bronx, NY. METHODS: A total of 1,920 children admitted to the hospital in Bronx, NY due to asthma during 2017-2019 period were included in the study. Demographic and clinical parameters were obtained from medical records. Daily ozone (O3) and fine particulate matter (PM2.5) measurements were obtained from local air quality networks. Poisson regression adjusting for gender, age, weight status, respiratory infections including influenza, and ambient temperature was applied to determine whether there was an association of air pollution with length of hospital stay. RESULTS: The mean LOS varied by age, sex, weight status, influenza vaccination status, respiratory viral panel (RVP) results, asthma controller use, and asthma classification. After controlling for these factors in Poisson regression, the mean LOS increased up to 10.62% (95%CI: 0.78-21.41; p = 0.03) for an increase of 10 µg/m3 of PM2.5 exposure on admission day, and 3.90% (95%CI = 0.06-7.88; p = 0.05) for an increase of 10 ppbv of O3 concentration during the previous day. CONCLUSION: Ambient particulate and ozone pollution is associated with lengthier hospital stays for pediatric asthma, potentially indicating more severe asthma exacerbations.

Prevalence and Factors Associated With Mycoplasma genitalium Infection in At-Risk Female Adolescents in Bronx County, New York.

BACKGROUND: Mycoplasma genitalium infection can adversely affect female reproductive health, but data are limited about prevalence and characteristics of the infection in female adolescents. We employed a sensitive assay to detect M. genitalium infection, and we describe its characteristics in a clinical sample of women younger than 21 years. METHODS: We recruited females aged 13 to 20 years in children's hospital clinics whose clinicians were testing for chlamydia/gonorrhea. Participants completed a questionnaire providing demographics, sexual history, and current symptoms. Urine/endocervical samples were tested for chlamydia/gonorrhea and partitioned for M. genitalium testing using Aptima M. genitalium assay. We reviewed records for the clinic visit to document examination, diagnosis, and results of sexually transmitted infection (STI) testing. We compared prevalence of M. genitalium infection by demographics, sexual history, symptoms, and signs. RESULTS: Of 153 participants mean age 18.07 ± 1.68 years, 58% self-identified as Hispanic, 27% Black, 64% straight/heterosexual, 27% bisexual, 1% gay/lesbian, 29% reported a prior STI diagnosis. Prevalence of M. genitalium was 11.1% (17/153), 13 of 17 were asymptomatic, 2 of 17 had pelvic inflammatory disease (PID), 3 of 17 coinfected with chlamydia or gonorrhea. Prevalence of chlamydia was 6.6% and of gonorrhea 2.6%. A logistic regression model indicated independent associations of bisexual orientation versus all other orientations (adjusted odds ratio [aOR], 4.80; 95% confidence interval [CI], 1.38-16.67), self-reported prior STI (aOR, 3.83; 95% CI, 1.10-13.37), and self-reported prior PID (aOR, 9.12; 95% CI, 1.02-81.72) with higher odds of M. genitalium infection. CONCLUSIONS: Findings suggest that in at-risk female populations younger than 21 years, M. genitalium is a prevalent STI and symptomatic adolescents may warrant testing and treatment. Further study of harms and benefits of testing asymptomatic bisexual female adolescents or those with prior STI/PID is needed.

Decreasing the Newborn Birth Hospitalization Length of Stay.

OBJECTIVES: This study aimed to determine our ability to shorten birth hospitalization length of stay (LOS) in which patient characteristics were associated with early discharge and had effects on early newborn readmission rate. STUDY DESIGN: Retrospective chart review of births from April 1, 2020 to December 31, 2020, was considered for this study. Delivery mode and maternal and newborn characteristics were evaluated for effect on discharge timing. Hospital readmissions within 7 days of discharge were reviewed. RESULTS: In total, 845 out of 1,077 total live births were included in the study population. Five hundred and eighty-nine (69.7%) newborns were discharged early (<48 hours after vaginal delivery [VD] and <72 hours after cesarean delivery [CS]). Factors associated with early discharge included 79.8% CS (p < 0.001), 84% birth after 2 p.m. (p < 0.001), 71.2% no diagnosis of maternal diabetes (p = 0.02), and 70.6% negative maternal coronavirus disease 2019 (p = 0.01). The overall 7-day readmission rate was 1.2 and 0.5% for newborns discharged early after VD. CONCLUSION: Most newborns can be discharged early without increasing newborn readmission. KEY POINTS: · Most patients were discharged <72 hours after CS.. · Most patients were discharged <48 hours after VD.. · Early discharge does not affect newborn readmissions..

Where Do We Go from here? Post-pandemic Planning and the Future of Graduate Medical Education.

Background: As the pandemic wanes, there is an opportunity to reevaluate resultant changes in graduate medical education (GME), particularly from the viewpoints of those affected most. We aimed to assess both trainee and faculty perceptions on the educational changes and innovations resulting from the pandemic to inform future educational planning. Methods: We surveyed trainees and core education faculty at three New York City children's hospitals. Surveys assessed perceived changes to educational activities, skills, scholarship, effectiveness of virtual teaching, future desirability, and qualitative themes. Results: The survey was completed by 194 participants, including 88 (45.4%) faculty and 106 (54.6%) trainees. Trainees were more likely to report a negative impact of the pandemic compared with faculty (75.5% vs. 50%, p < 0.01). Most respondents reported a decrease in formal educational activities (69.8%), inpatient (77.7%) and outpatient (77.8%) clinical teaching. Despite this, most perceived clinical and teaching skills to have stayed the same. Most (93.4%) participated in virtual education; however, only 36.5% of faculty taught virtually. Only 4.2% of faculty had extensive training in virtual teaching and 28.9% felt very comfortable teaching virtually. In the future, most (87.5%) prefer a hybrid approach, particularly virtual didactic conferences and virtual grand rounds. Faculty themes included challenges to workflows and increased empathy for trainees, while trainee themes included increased work/life balance and support, but increased burnout. Conclusion: Many changes and innovations resulted from the pandemic. Hospital systems and GME programs should consider this data and incorporate viewpoints from trainees and faculty when adapting educational strategies in the future.

Impact of magnetic resonance angiography parameters on stroke prevention therapy in pediatric patients with sickle cell anemia.

BACKGROUND: Degree of cerebrovascular stenosis in pediatric patients with sickle cell anemia (SCA) informs need for chronic transfusion therapy, which has significant risks. Flow artifact, intrinsic to magnetic resonance angiography (MRA), is dependent on technical parameters and can lead to overinterpretation of stenosis. The primary objective of this study was to document any change in stroke prevention therapy that could be attributed to the implementation of a standardized MRA scanning protocol for patients with SCA. METHODS: A standardized MRA scanning protocol with an echo time of less than 5 ms was implemented at Montefiore Medical Center (MMC), NY in May 2016. Retrospective chart review identified 21 pediatric patients with SCA, with an MRA head both pre- and post-May 2016. Arterial stenosis on MRA, machine parameters, and treatment plans were compared pre- and post-implementation. RESULTS: Ten of the 21 patients met inclusion criteria. Previously seen stenosis was re-classified to a lower degree in six of the 10 patients, leading to discontinuation of transfusions in five patients. No patients required escalation of therapy to chronic transfusions. CONCLUSION: Optimizing flow artifact by decreasing echo time to less than 5 ms can improve accurate interpretation of cerebrovascular disease, and ensure appropriate treatment plans are in place for stroke prevention. This is especially important for implementing "TCD With Transfusions Changing to Hydroxyurea (TWiTCH)" clinical trial results in the real-world setting.

Treatment of Attention-Deficit/Hyperactivity Disorder with Medication in Children with Autism Spectrum Disorder With and Without Intellectual Disability: A DBPNet Study.

Children with autism spectrum disorder (ASD) and intellectual disability (ID)/global delay (GD) frequently have symptoms of attention-deficit/hyperactivity disorder (ADHD). We describe the practice patterns of developmental behavioral pediatricians (DBPs) in the treatment of children with ASD and coexisting ADHD and compare medication classes for children with and without intellectual disability. In bivariate analyses, we compared demographic characteristics, co-occurring conditions, and medication classes for children with and without intellectual disability. Significantly more patients with ID/GD were prescribed α-agonists than patients without ID/GD, but the difference was no longer significant when controlling for age in logistic regression children with ID/GD had more comorbidities and were more likely to be prescribed more than on psychotropic medication. In conclusion, age rather than ID/GD was associated with medication choice.

Comparison of Children Hospitalized for Asthma Before and During the COVID-19 Pandemic.

Background: Studies suggest that children with asthma experienced improved symptom control and less frequent inpatient admission during the COVID-19 (coronavirus disease 2019) pandemic. The characteristics of hospitalized children remain less well defined. Methods: This retrospective cohort study compared patients admitted for asthma during the pandemic with patients hospitalized the year prior at a children's hospital in the Bronx, New York. Results: In the year before the pandemic, 667 children were hospitalized for asthma, compared with 177 children the following year. Children admitted during the pandemic were older (7.8 versus 7.0 years, P = 0.04), more likely underweight (P < 0.01), and more likely to have public insurance (P = 0.02). Additionally, children hospitalized during the pandemic required intensive care (P = 0.03) and magnesium sulfate (P = 0.05) more frequently. Despite this, length of stay remained similar. Conclusion: While inpatient utilization for asthma decreased during the pandemic, children hospitalized were sicker on presentation. The cause of this is likely multifactorial and requires further study.

Parental Depression and Anxiety Associated with Newborn Bloodspot Screening for Rare and Variable-Onset Disorders.

The ability to screen newborns for a larger number of disorders, including many with variable phenotypes, is prompting debate regarding the psychosocial impact of expanded newborn bloodspot screening (NBS) on parents. This study compares psychological outcomes of parents of children with a range of NBS/diagnostic experiences, with a particular focus on lysosomal storage disorders (LSDs) and X-linked adrenoleukodystrophy (X-ALD) as representative disorders with complex presentations. An online cross-sectional survey with six domains was completed in 2019 by a volunteer sample of parents with at least one child born between 2013 and 2018. Parents were classified in the analysis stage into four groups based on their child's rare disorder and means of diagnosis. Stress and depression were estimated using dichotomous measures of the depression subscale of the Hospital Anxiety and Depression Scale and the Parental Stress Scale. Logistic regression models were estimated for the relationship between the parent group and stress/depression, controlling for demographic variables (region of the US, income, education, major life events, relationship to the child, number of children, parent age, and race/ethnicity). One hundred seventy-four parents were included in this analysis. Parents of children with an LSD or X-ALD diagnosis clinically may have higher odds of depression (OR: 6.06, 95% CI: 1.64-24.96) compared to parents of children with the same disorders identified through NBS, controlling for covariates. Although a similar pattern was observed for parental stress (OR: 2.85, 95% CI: 0.82-10.37), this did not reach statistical significance. Ethically expanding NBS and genome sequencing require an understanding of the impacts of early detection for complex disorders on families. These initial findings are reassuring, and may have implications as NBS expands. Given our small sample size, it is difficult to generalize these findings to all families. These preliminary trends warrant further investigation in larger and more diverse populations.

Associations of Pediatric Symptom Checklist Scores with Sexual Activity and Sexually Transmitted Infections in Urban Adolescents.

OBJECTIVE: To assess the association between the Youth Pediatric Symptom Checklist-17 (YPSC-17) and adolescents' reports of ever having sex and with having positive testing results for sexually transmitted infections (STIs). METHODS: Analyzed electronic data from primary care clinics for 27,901 adolescents aged 13-17 years with responses to the YPSC-17 and urine screen results for gonorrhea/chlamydia. RESULTS: On the YPSC-17 in total 8.3% screened positive. Over one quarter (26%) reported ever having sex and 11% of sexually active youth had a positive STI test. Logistic regression analyses revealed increased odds of sexual activity among those positive on the YPSC-17 total (aOR 1.87, 95% CI 1.68-2.08) or any subscale (INT-aOR 1.43, 95% CI 1.32-1.55; EXT-aOR 1.62, 95% CI 1.40-1.88; ATT-aOR 1.67, 95% CI 1.47-1.90). In addition, sexually active youth with positive EXT (aOR 1.41 95% CI 1.00-1.98) scores were more likely to have STIs. CONCLUSION: The YPSC-17 can identify adolescents with heightened risks for STIs.

Modified DIVA Score: An Improved Clinical Predictive Tool for Detecting Difficult Access in Children.

OBJECTIVE: This study aims to validate the DIVA (Difficult Intravenous Access) score in our population and to identify any additional patient characteristics that may be associated with difficult access in children. METHODS: This was a cross-sectional study in an urban quaternary pediatric emergency department with patients younger than 21 years and Emergency Severity Index ≥2 who require intravenous (IV) access for their management. In addition to patient characteristics comprising the DIVA score, data were collected on patient "history of difficult access," hydration status, skin shade, history of sickle cell disease or diabetes, technology dependence, and body mass index. The number of IV cannulation attempts and total time taken were recorded for each patient. "Difficult access" was defined as ≥2 or more attempts or time >30 minutes to achieve successful IV cannulation. RESULTS: A convenience sample of 300 pediatric patients was enrolled. The DIVA score had a sensitivity of 51% (95% confidence interval [CI], 40.8%-61.14%) and a specificity of 82.99% (95% CI, 76.95%-87.99%) for predicting "difficult access" in our population. Among all patient characteristics examined in this study, only "history of difficult access" improved the identification of "difficult access" patients. The "history of difficult access" variable had a sensitivity of 61% (95% CI, 50.7%-70.6%) and a specificity of 75.7% (95% 95% CI, 69.12%-81.62%) in predicting "difficult access." With the addition of "history of difficult access" to the original DIVA score, we developed a "modified DIVA score (m-DIVA)." The m-DIVA score had a sensitivity of 78% (95% CI, 68.6%-85.6%) and specificity of 67% (95% CI, 59.9%-73.58%), representing a 52.9% improvement in correctly identifying "difficult access" patients over the original DIVA score. CONCLUSIONS: The m-DIVA score, which incorporates prior history, increases the screening test's sensitivity in identifying "difficult access" patients and should be further investigated as clinical tool.

Referral Patterns for Emergency Psychiatric Evaluations and Effect of School Mental Health Services in New York City, 2018.

BACKGROUND: Pediatric mental health issues are increasing while access to care is decreasing. This is reflected in a growing number of patients seeking emergency psychiatric evaluations (EPEs) in the emergency department (ED). METHODS: This was a retrospective review of patients seeking EPE in the ED of a children's hospital between September and December 2018, which compares patients referred from the community versus those from schools as well as patients from schools with and without school-based mental health services (SMH). RESULTS: A total of 546 EPEs were analyzed, with 187 (34%) referred from schools. School referrals were younger, had a shorter length of stay and lower admission rates. When comparing those from schools with SMH, those referred from schools without SMH were younger and less acutely ill. CONCLUSIONS: Higher acuity children from schools with SMH suggest that SMH staff managed less severe situations on site. The role of SMH as a triaging tool and provider of mental health services should be studied as they may reduce the burden on EDs for EPEs.

Clinical, Laboratory and Radiographic Features Associated With Prolonged Hospitalization in Children With Complicated Appendicitis.

Objective: In children with appendicitis, rupture of the appendix is associated with a significant increase in morbidity. We sought to characterize the spectrum of illness in children with complicated appendicitis and to define those factors associated with a longer hospital stay. Study Design: We conducted a retrospective review of 132 children, 18 years of age or younger at a large urban teaching hospital in the Bronx, NY between October 2015 and April 2018 with an intraoperative diagnosis of perforated appendix. Clinical, laboratory and radiologic findings were reviewed, and the primary study outcome was length of stay (LOS) dichotomized at the median, which was 7 days. Statistical analyses were done to characterize morbidity and define variables predictive of longer stay. Results: Children in the longer LOS group experienced significantly more morbidity, including ICU stay, ileus, and need for multiple drainage procedures. A longer duration of symptoms prior to presentation was associated with a longer stay. Multivariable logistic regression analysis indicated that the presence of abscess and presence of free fluid in the right upper quadrant (RUQ FF) on initial imaging and C-reactive protein (CRP) level >12 at admission, were independently associated with a longer stay. Conclusion: There is considerable variation in the morbidity of complicated appendicitis. The association between longer stay and the findings of abscess and RUQ FF on initial imaging along with an elevated CRP may provide a useful tool in identifying those children at risk for worse outcomes.

A Lung Cancer Screening Education Program Impacts both Referral Rates and Provider and Medical Assistant Knowledge at Two Federally Qualified Health Centers.

BACKGROUND: Federally Qualified Health Centers (FQHCs) serve minority and low-socioeconomic populations and provide care to high-risk smokers. These centers frequently experience barriers, including low provider and medical assistant (MA) knowledge around lung cancer screening (LCS). Subsequent low LCS referral rates by providers at FQHCs limit utilization of LCS in eligible, high-risk, underserved patients. METHODS: Providers and MAs from two FQHCs participated in a LCS educational session. A pre-educational survey was administered at the start of the session and a post-educational survey at the end. The intervention included a presentation with education around non-small cell lung cancer, LCS, tobacco cessation, and shared-decision making. Both surveys were used to evaluate changes in provider and MA ability to determine eligible patients for LCS. The Pearson's Chi-squared test with Yates' continuity correction was used to measure the impact. RESULTS: A total of 29 providers and 28 MAs enrolled in the study from two FQHCs. There was an improvement, P < .009 and P < .015 respectively, in provider and MA confidence in identifying patients for LCS. Additionally, one year prior to the program, 9 low-dose computed tomography (LDCTs) were ordered at one of the FQHCs and 0 at the other. After the program, over 100 LDCTs were ordered at each FQHC. CONCLUSIONS: A targeted LCS educational program improves provider and MAs' ability to identify eligible LCS patients and is associated with an increase in the number of patients referred to LDCT at FQHCs.

Do Referral Factors Predict a Probable Autism Spectrum Disorder Diagnosis? A DBPNet Study.

OBJECTIVE: To determine the proportion of children referred to academic medical centers with concerns about autism spectrum disorders (ASDs) who received a probable ASD diagnosis, identify factors predicting ASD diagnosis, and describe the children with ASD concerns who were not found to have autism. METHODS: A total of 55 developmental-behavioral pediatricians (DBP) at 12 academic sites in the DBPNet research network recorded data on ≤15 consecutive new patients. They coded presumed diagnoses after their first visit with the child. RESULTS: Of 784 new visits, 324 (41%) had concern for ASD; of these, 221 (68%) were presumptively ASD+; 103 (32%) were ASD-. In a mixed model accounting for clustering within site and covariates significant in bivariate analysis, significant predictors of receiving a presumptive ASD diagnoses were socialization concerns, languages other than English spoken in the home, and coming for second opinion. Also concern for "other behavior problems" (not mood, oppositionality, anxiety, attention, or repetitive behaviors) predicted not receiving ASD diagnoses. This model was not clinically useful because it misclassified 26.9% of children. ASD- children <4 years old had more language delay and less cognitive impairment and socialization concern than their ASD+ age peers. ASD- children ≥4 years old were more likely to have attention-deficit /hyperactivity disorder (ADHD) and learning disability with normal cognition than their ASD+ age peers. CONCLUSIONS: Two thirds of children referred to academic centers with concern for ASD received a presumptive diagnosis of ASD. While those with ASD were not easily distinguished from those without ASD at referral, virtually all children with ASD concerns had multiple DBP diagnoses made and required DBP follow-up care.

Impact of Z score system on the management of coronary artery lesions in Kawasaki disease.

BACKGROUND: Coronary artery aneurysms are well-described in Kawasaki disease and the Multisystem Inflammatory Syndrome in Children and are graded using Z scores. Three Z score systems (Boston, Montreal, and DC) are widely used in North America. The recent Pediatric Heart Network Z score system is derived from the largest diverse sample to-date. The impact of Z score system on the rate of coronary dilation and management was assessed in a large real-world dataset. METHODS: Using a combined dataset of patients with acute Kawasaki disease from the Children's Hospital at Montefiore and the National Heart, Lung, and Blood Institute Kawasaki Disease Study, coronary Z scores and the rate of coronary lesions (Z ≥ 2.0) and aneurysms (Z ≥ 2.5) were determined using four Z score systems. Agreement among Z scores and the effect on Kawasaki management were assessed. RESULTS: Of 333 patients analysed, 136 were from Montefiore and 197 from the Kawasaki Disease Study. Age, sex, body surface area, and rate of coronary lesions did not differ between the samples. Among the four Z score systems, the rate of acute coronary lesions varied from 24 to 55%. The mean left anterior descending Z scores from Pediatric Heart Network and Boston had a large uniform discrepancy of 1.3. Differences in Z scores among the four systems may change anticoagulation management in up to 22% of a Kawasaki population. CONCLUSIONS: Choice of Z score system alone may impact Kawasaki disease diagnosis and management. Further research is necessary to determine the ideal coronary Z score system.
