A Multimodal Intervention to Reduce C. difficile Infections and Stool Testing.

BACKGROUND AND OBJECTIVES: The introduction of multiplex gastrointestinal panels at our institution resulted in increased Clostridioides difficile (C. difficile) detection and stool test utilization. We aimed to reduce hospital-onset C. difficile infections (HO-CDIs), C. difficile detection, and overall stool testing by 20% within 1 year. METHODS: We conducted a quality improvement project from 2018 to 2020 at a large children's hospital. Interventions included development of a C. difficile testing and treatment clinical care pathway, new options for gastrointestinal panel testing with or without C. difficile (results were suppressed if not ordered), clinical decision support tool to restrict testing, and targeted prevention efforts. Outcomes included the rate of HO-CDI (primary), C. difficile detection, and overall stool testing. All measures were evaluated monthly among hospitalized children per 10 000 patient-days (PDs) using statistical process-control charts. For balancing measures, we tracked suppressed C. difficile results that were released during real-time monitoring because of concern for true infection and C. difficile-related adverse events. RESULTS: HO-CDI decreased by 55%, from 11 to 5 per 10 000 PDs. C. difficile detection decreased by 44%, from 18 to 10 per 10 000 PDs, and overall test utilization decreased by 29%, from 99 to 70 per 10 000 PDs. The decrease in stool tests resulted in annual savings of $55 649. Only 2.3% of initially suppressed positive C. difficile results were released, and no patients had adverse events. CONCLUSIONS: Diagnostic stewardship strategies, coupled with an evidence-based clinical care pathway, can be used to decrease C. difficile and improve overall test utilization.

Decrease in Rates of Hearing Loss From Pediatric Bacterial Meningitis Over Time: A Database Review.

OBJECTIVES: Bacterial meningitis is a leading cause of acquired sensorineural hearing loss (SNHL). Treatment and prevention of bacterial meningitis have improved over time, but rates of neurologic complications have not been recently studied. The objective here is to present an updated population-based review of hearing loss as a sequela of bacterial meningitis. METHODS: A retrospective cohort study was conducted between 2010 and 2022 of children discharged with bacterial meningitis, using the Pediatric Health Information System's (PHIS) database. Rates of hearing loss and mortality were evaluated over time. RESULTS: A total of 6138 children with a primary diagnosis of bacterial meningitis were identified (3520 male [57.3%], mean age 5.8 months [2.0, 61.2]). Of these, 277 (4.51%) were diagnosed with hearing loss. Children with hearing loss were significantly older (23.6 vs. 5.3 months, p < 0.01), but differences in gender, race, or ethnicity had no association with hearing loss. Streptococcus pneumoniae, Hemophilus influenzae, and Neisseria meningiditis were associated with significantly higher rates of hearing loss than other etiologies (p < 0.01). Children with hearing loss had a higher rate of receiving dexamethasone than children without hearing loss. Overall mortality rate was 2.1%. Hearing loss and mortality demonstrated significant decreases over the study period. CONCLUSION: Hearing loss remains a common sequela of bacterial meningitis despite widespread uptake of vaccines for preventing S. pneumoniae, H. influenzae, and N. meningitidis. Dexamethasone was not associated with decreased rates of hearing loss in this cohort. From 2010 to 2022, there was a significant decrease in overall rates of mortality and hearing loss for children with bacterial meningitis.

The Fit After Baby randomized controlled trial: An mHealth postpartum lifestyle intervention for women with elevated cardiometabolic risk.

BACKGROUND: Postpartum women with overweight/obesity and a history of adverse pregnancy outcomes are at elevated risk for cardiometabolic disease. Postpartum weight loss and lifestyle changes can decrease these risks, yet traditional face-to-face interventions often fail. We adapted the Diabetes Prevention Program into a theory-based mobile health (mHealth) program called Fit After Baby (FAB) and tested FAB in a randomized controlled trial. METHODS: The FAB program provided 12 weeks of daily evidence-based content, facilitated tracking of weight, diet, and activity, and included weekly coaching and gamification with points and rewards. We randomized women at 6 weeks postpartum 2:1 to FAB or to the publicly available Text4baby (T4B) app (active control). We measured weight and administered behavioral questionnaires at 6 weeks, and 6 and 12 months postpartum, and collected app user data. RESULTS: 81 eligible women participated (77% White, 2% Asian, 15% Black, with 23% Hispanic), mean baseline BMI 32±5 kg/m2 and age 31±5 years. FAB participants logged into the app a median of 51/84 (IQR 25,71) days, wore activity trackers 66/84 (IQR 43,84) days, logged weight 17 times (IQR 11,24), and did coach check-ins 5.5/12 (IQR 4,9) weeks. The COVID-19 pandemic interrupted data collection for the primary 12-month endpoint, and impacted diet, physical activity, and body weight for many participants. At 12 months postpartum women in the FAB group lost 2.8 kg [95% CI -4.2,-1.4] from baseline compared to a loss of 1.8 kg [95% CI -3.8,+0.3] in the T4B group (p = 0.42 for the difference between groups). In 60 women who reached 12 months postpartum before the onset of the COVID-19 pandemic, women randomized to FAB lost 4.3 kg [95% CI -6.0,-2.6] compared to loss in the control group of 1.3 kg [95% CI -3.7,+1.1] (p = 0.0451 for the difference between groups). CONCLUSIONS: There were no significant differences between groups for postpartum weight loss for the entire study population. Among those unaffected by the COVID pandemic, women randomized to the FAB program lost significantly more weight than those randomized to the T4B program. The mHealth FAB program demonstrated a substantial level of engagement. Given the scalability and potential public health impact of the FAB program, the efficacy for decreasing cardiometabolic risk by increasing postpartum weight loss should be tested in a larger trial.

Factors associated with postpartum depression among high-risk women during the COVID-19 pandemic.

The purpose of this study was to investigate the impacts of the COVID-19 pandemic on multi-level factors associated with depression among a high-risk sample of postpartum women using longitudinal data collected at two timepoints. High-risk postpartum participants in the United States were recruited to participate in a parent study focused on mitigating risk of cardiometabolic disease in postpartum women. Individuals completed a baseline survey which included the Edinburgh Postpartum Depression Scale (EPDS) at 6-weeks postpartum between 2017 through 2019. A modified survey with the inclusion of selected questions from the Coronavirus Health Impact Survey (CRISIS) questionnaire was administered again during the first 6-months of the COVID-19 pandemic and individuals who completed both the baseline assessment and the COVID-19 assessment were included for analyses (n = 46). Multivariate models were run to investigate the impacts of individual-, interpersonal-, and structural-level factors on change in EPDS scores across the postpartum period. Findings suggest that losing contact with social supports (ß = 4.5, SE = 1.9, p = .02) and individuals who reported a total household income of less than $75,000 (ß = 3.4, SE = 1.7, p = .05) were more likely to report significantly worsening postpartum depression scores compared to others. Recommendations to mitigate the stressors that have been amplified by the COVID-19 pandemic and resulting mental health disparities include screening all high-risk postpartum women for depression and anxiety during both postpartum and pediatric healthcare visits, providing informational flyers with tips related to healthy coping behaviors and free/affordable community resources, and linking individuals to peer-led support groups.

Olfactory dysfunction and training in children with COVID-19 infection: A prospective study Post-COVID pediatric olfactory training.

OBJECTIVE: Postviral olfactory dysfunction (OD) including corona 2019 viral disease (COVID-19) OD occurs in both adults and children. Despite limited reports of efficacy in treating adult postviral including COVID-19 OD with olfactory training (OT), its effects on children in general, and post-COVID-19 in specific, is unknown. The study aimed at evaluating the effects of OT in a COVID-19 OD pediatric cohort. METHODS: A single-arm prospective study of pediatric COVID-19 OD subjects confirmed by the University of Pennsylvania Smell Identification Test (UPSIT), was conducted. All subjects underwent OT by sniffing 4 odorants (lavender, orange, peppermint, and eucalyptus) for 1 min twice a day for 3 months. Subjects underwent an odorant identification test (OIT) of the 4 odorants each visit. A repeat UPSIT was administered at the 4th visit. RESULTS: The study enrolled a total of 37 subjects [11 males/26 females with mean age/standard deviation (std) of 15.6(2.1) years]. The time interval between COVID-19 and entry was 5.3(2.4) months. The mean pre/post study UPSIT score improvement was 2.3(4.7), p = .09. OIT scores between entry and 3 subsequent visits showed a mean improvement of 1.8(1.5), 1.8(1.9) and 2.3(1.9) odorants, respectively, with P < .001 for all 3 comparisons. CONCLUSIONS: OT subjects were predominantly female teens with substantial OD lasting greater than 5 months. OT did not affect OD as measured by UPSIT but OIT scores improved during OT. We postulate that OT likely has a role in pediatric post-COVID OD recovery, but UPSIT likely is too rigid to detect disparate odorant improvement.

High Prevalence of Obstructive Sleep-Disordered Breathing in Pediatric Patients With Turner Syndrome.

OBJECTIVE: Girls with Turner syndrome (TS) often have features that have been associated with obstructive sleep-disordered breathing (oSDB). However, little is known about oSDB in TS. Herein, we aimed to characterize oSDB in young patients with TS and identify associated risk factors. STUDY DESIGN: Retrospective cross-sectional study. SETTING: Tertiary care pediatric hospital. METHODS: We reviewed medical records for patients diagnosed with TS seen at our institution between October 1, 2007 and December 31, 2019 with the first outpatient visit before age 6 years. The prevalence of oSDB was compared to the general pediatric population with 1-sample binomial proportion tests. Clinical characteristics were compared between those diagnosed with oSDB and those without oSDB, and risk factors for oSDB were identified. RESULTS: Of 151 patients with TS, 73 (48%) were diagnosed with oSDB which is 4-fold higher than the general pediatric population (12%, P < 0.0001). In the multivariable model, adenoid, tonsillar, and inferior turbinate hypertrophy, birthweight, failure to thrive, and older age at the last clinic visit were all associated with increased odds for oSDB. CONCLUSION: Young children with TS have a high prevalence of oSDB and thus should be screened for oSDB. Polysomnography should be performed in those with associated risk factors and symptoms oSDB. Treatment of oSDB is imperative as individuals with TS are already at increased risk of behavioral problems, neurocognitive deficits, and growth impairment that may be worsened with oSDB.

The Impact of Mental Health Symptoms in Children With Tinnitus and Misophonia: A Multi-disciplinary Approach.

Tinnitus and misophonia are important "sound annoyance" disorders in pediatric otolaryngology and audiology practices. There is scant published literature to suggest increased anxiety and depression symptoms in these disorders. This study aimed at assessing the clinical characteristics of these 2 disorders and their prevalence in mental health-related symptoms in a 2-year retrospective chart review of a multi-disciplinary (otolaryngology, audiology, and psychology) clinic cohort. Analyses were based on 54 (tinnitus = 33 and misophonia = 21) children consisting of 19 males and 35 females with a mean age (standard deviation) of 14.3 (3.0) years. The entire cohort was negatively affected by diagnosis-based symptom severity instruments as assessed by Tinnitus Functional Index and Amsterdam Misophonia Scale. Both subgroups exhibited elevated anxiety and depression symptoms in psychometric instruments as assessed by Screen for Child Anxiety Related Emotional Disorders and Short Mood and Feelings Questionnaire. Evidence-based management of these disorders is lacking, and clinical trials are needed.

Randomized-controlled trial of a whole-family obesity prevention and treatment intervention designed for low-income Hispanic families: HeLP the healthy living program.

BACKGROUND: Low-income Hispanic families face marked disparities in obesity, but interventions for obesity prevention and treatment have rarely been designed with this population as a focus. Hispanic culture is characterized by Familism, a value that prioritizes familial respect, cooperation, and togetherness. We describe the rationale and design of a trial of the Healthy Living Program (HeLP), a bilingual whole-family behavioral obesity prevention and treatment intervention designed around the value Familism and addressing food insecurity. METHODS/DESIGN: This two-group randomized comparative effectiveness trial will compare the effects of HeLP versus a primary care counseling intervention (Recommended Treatment of Obesity in Primary Care, or RTOP) on decreasing body mass index (BMI; kg/m2) in Hispanic children 2-16 years of age with obesity and preventing BMI increase among siblings without obesity. 164 families per arm will be recruited from primary care practices. Families randomized to HeLP will participate in 12 two-hour sessions, followed by booster sessions. HeLP sessions include family meals and instruction in parenting skills, nutrition, culinary skills, fitness, and mindfulness delivered at community recreation centers by bilingual health educators and athletic trainers. Families randomized to RTOP will be offered individual visits in primary care every 3 months throughout the 18-month follow-up period. Secondary outcomes include changes to objectively measured child fitness, the home environment related to nutrition, physical activity, and media usage, food insecurity, child eating behaviors, quality of life, parent BMI and waist circumference, and implementation outcomes. DISCUSSION: This protocol paper describes the rationale and planned methods for the comparative effectiveness trial. TRIAL REGISTRATION: Clinicaltrials.gov Identifier NCT05041855 (6/13/2023).

Quality Improvement Campaign Improved Utilization of Rapid Sequence MRI for Diagnosis of Pediatric Appendicitis.

INTRODUCTION: Appendicitis is the most common indication for emergency general surgery in the pediatric population. Computed tomography (CT) or magnetic resonance imaging (MRI) may be used for diagnosis when ultrasound findings are equivocal. However, CT involves unnecessary radiation exposure if MRI is available. After introducing a rapid sequence MRI (rsMRI) appendicitis protocol at our institution, CT was still preferentially used. We therefore implemented a quality improvement (QI) campaign to reduce the rate of CTs and increase the rate of rsMRI. Here, we assess the effectiveness of the QI campaign while evaluating potential barriers to using rsMRI. METHODS: We conducted a mixed methods study, first performing stakeholder interviews which informed the design of a QI campaign initiated in May 2021 and a midway feedback survey in December 2021. A retrospective cohort study was then performed of children evaluated for appendicitis at our institution between January 1, 2016, and April 30, 2022. CT and rsMRI rates were compared before and after QI campaign implementation. RESULTS: There was a significant decrease in rate of CTs and increase in rate of rsMRIs performed following the initiation of the QI campaign (p < 0.0001). The rate of CT scans decreased by a factor of 0.4 while the rate of rsMRI increased by a factor of 9.5. CONCLUSION: A successful QI campaign was initiated at our institution, resulting in decreased utilization of CT and increased use of rsMRI for the evaluation of suspected appendicitis. These results highlight the potential impact of QI projects. LEVEL OF EVIDENCE: III.

Implementation of the Cardiac Inpatient Neurodevelopmental Care Optimization (CINCO) programme: an interdisciplinary, generalisable approach to inpatient neurodevelopmental care.

BACKGROUND: Children with CHD are at risk for neurodevelopmental delays, and length of hospitalisation is a predictor of poorer long-term outcomes. Multiple aspects of hospitalisation impact neurodevelopment, including sleep interruptions, limited holding, and reduced developmental stimulation. We aimed to address modifiable factors by creating and implementing an interdisciplinary inpatient neurodevelopmental care programme in our Heart Institute. METHODS: In this quality improvement study, we developed an empirically supported approach to neurodevelopmental care across the continuum of hospitalisation for patients with CHD using three plan-do-study-act cycles. With input from multi-level stakeholders including parents/caregivers, we co-designed interventions that comprised the Cardiac Inpatient Neurodevelopmental Care Optimization (CINCO) programme. These included medical/nursing orders for developmental care practices, developmental kits for patients, bedside developmental plans, caregiver education and support, developmental care rounds, and a specialised volunteer programme. We obtained data from the electronic health record for patients aged 0-2 years admitted for at least 7 days to track implementation. RESULTS: There were 619 admissions in 18 months. Utilisation of CINCO interventions increased over time, particularly for the medical/nursing orders and caregiver handouts. The volunteer programme launch was delayed but grew rapidly and within six months, provided over 500 hours of developmental interaction with patients. CONCLUSIONS: We created and implemented a low-cost programme that systematised and expanded upon existing neurodevelopmental care practices in the cardiac inpatient units. Feasibility was demonstrated through increasing implementation rates over time. Key takeaways include the importance of multi-level stakeholder buy-in and embedding processes in existing clinical workflows.

Hearing outcomes in children with pneumococcal meningitis in the PCV13 era.

INTRODUCTION: Streptococcus pneumoniae, is associated with the highest incidence of post-meningitic SNHL. The exact impact of 13-valent pneumococcal conjugate vaccine (PCV) on pediatric SNHL from pneumococcal meningitis is unknown. We aimed to identify clinical factors associated with post-meningitic SNHL (pmSNHL) from pneumococcal meningitis and describe its rates based on three time periods: pre-PCV, PCV-7 and PCV13 eras. METHODS: A retrospective case-control study was performed for patients 18 years and younger diagnosed with pneumococcal meningitis from January 1, 2010 to December 31, 2020 at Children's Hospital Colorado. Demographic and clinical risk factors between those with or without SNHL were compared. Detailed hearing outcomes of those with resulting SNHL are described. RESULTS: 23 patients with CSF cultures or Meningitis/Encephalitis Panel positive for pneumococcal meningitis were identified. Twenty patients both survived the infection and had audiologic evaluation. Six patients had pmSNHL, with 50 % affected bilaterally. The rate of pmSNHL from S. pneumoniae in the PCV-13 era at our institution was similar to historical rates from the pre-PCV and PCV-7 eras. Similar proportions of patients with pmSNHL completed PCV vaccination (66.7 %) compared to those without (71.4 %). Non-PCV-13 serotypes were responsible 83 % of patients with pmSNHL versus 57 % of patients without pmSNHL. CONCLUSIONS: Despite high rates of PCV-13 uptake in our cohort, pmSNHL was still common, severe, and commonly associated with non-PCV-13 serotypes. Non-PCV-13 serotypes may be contributing to the persistently high rate of post-meningitic SNHL and the severity of SNHL. Newer pneumococcal conjugate vaccines with expanded serotypes may help mitigate the SNHL associated with pneumococcal meningitis.

Early outcomes of a myofascial repair technique for fetal myelomeningocele.

PURPOSE: Fetal repair of myelomeningocele (MMC) and myeloschisis leads to improved neurologic outcomes compared to postnatal repair, but the effects of modifications in closure techniques have not been extensively studied. Previous work has suggested that a watertight repair is requisite for improvement in hindbrain herniation (HBH) and to decrease postnatal hydrocephalus (HCP). Our institution adopted the myofascial closure technique for open fetal MMC repair in July 2019, which we hypothesized would result in decreased need for patch closure, improved HBH, and decreased rate of surgically-treated HCP. METHODS: A single-center retrospective study of patients who underwent fetal MMC or myeloschisis repair between March 2013 and February 2022 was performed. Outcomes were evaluated (n = 70 prior to July 2019, n = 34 after July 2019). Statistical significance was determined by Fisher's exact and Chi square tests (p < 0.05 significant). RESULTS: Patients who underwent myofascial closure were less likely to require a patch for skin closure (14.7% vs 58.6%, p < 0.0001). Myofascial closure was also associated with an increased rate of HBH improvement on two-week postoperative fetal MRI (93.9% vs 65.7%, p = 0.002). Surgically-treated HCP at one year was lower in the myofascial closure group (n = 21), however this did not reach statistical significance (23.8% vs 41.9%, p = 0.19). CONCLUSIONS: We conclude that the myofascial closure technique for repair of fetal MMC and myeloschisis is associated with significantly decreased need for patch closure and improvement in hindbrain herniation compared to our previous skin closure technique. These results support a surgical approach that employs a multilayer watertight closure.

Factors associated with new mental health diagnoses and resource utilization among pediatric patients following trauma admission.

PURPOSE: Injured children are at risk for a variety of physical and emotional sequelae that may impair their ability to return to prior function. The effect of traumatic injury on mental health in children is not well characterized or understood. We sought to determine factors associated with new mental health diagnoses and/or mental health resource utilization following admission to a Level 1 pediatric trauma center for traumatic injury. METHODS: A retrospective chart review of patients admitted for accidental trauma between 2016 and 2019 was performed. Demographic data, injury characteristics, new mental health diagnoses and/or mental health resource utilization following hospitalization were extracted. Patients with prior mental health diagnosis, psychotropic prescription(s), or resource utilization were excluded from this cohort. A multivariable logistic regression model was used to examine predictors of new mental health diagnoses and/or resource utilization. RESULTS: The prevalence of new mental health diagnoses or resources utilization was 9.5% (363/3828). The most common diagnoses were anxiety disorders and nonbipolar depression. The most common psychotropic medication prescribed was antidepressants. Patients with new mental illness were older (odds ratio [OR] 1.1 [95% CI: 1.06, 1.12]), more likely to sustain burn injuries (OR 6.3 [4.2, 9.5]), have non-sports related injuries (OR 3.5 [2.1, 6.0]), and be pedestrian struck (OR 2.7 [1.5, 4.8]). They additionally were more likely to sustain head, neck, and spine injuries (OR 3.8 [2.9, 5.1], 2.4 [1.1, 5.5], and 2.1 [1.3, 3.3], respectively). CONCLUSIONS: There are a variety of demographic and injury specific factors associated with new mental health diagnoses and/or resource utilization in children following admission for trauma. Knowledge of these risk factors may ensure patients are allocated adequate resources to promote timely access to appropriate mental health services after hospitalization. TYPE OF STUDY: Retrospective comparative study LEVEL OF EVIDENCE: III.

Impact of State Prioritization of Safe Infant Sleep Programs on Supine Sleep Positioning for Non-Hispanic White and Non-Hispanic Black Infants.

OBJECTIVE: Investigate whether safe infant sleep prioritization by states through the Title V Maternal and Child Block Grant in 2010 differentially impacted maternal report of supine sleep positioning (SSP) for Non-Hispanic White (NHW) and Non-Hispanic Black (NHB) U.S.-born infants. STUDY DESIGN: We analyzed retrospective cross-sectional data from the Pregnancy Risk Assessment Monitoring System (PRAMS) from 2005 to 2015 from 4 states: WV and OK (Intervention) and AR and UT (Control). PRAMS is a population-based surveillance system of maternal perinatal experiences which is linked to infant birth certificates. Piece-wise survey linear regression models were used to estimate the difference in the change in slopes of SSP percents in the pre- (2005-2009) and post- (2011-2015) periods, controlling for maternal and infant characteristics. Models were also stratified by race/ethnicity. RESULTS: From 2005 to 2015, for NHW infants, SSP improved from 61.5% and 70.2% to 82.8% and 82.3% for intervention and control states, respectively. For NHB infants, SSP improved from 30.6% and 26.5% to 64.5% and 53.1% for intervention and control states, respectively. After adjustment for maternal characteristics, there was no difference in the rate of SSP change from the pre- to post- intervention periods for either NHW or NHB infants in intervention or control groups. CONCLUSION: Compared with control states that did not prioritize safe infant sleep in their 2010 Title V Block Grant needs assessment, intervention states experienced no difference in SSP improvement rates for NHW and NHB infants. While SSP increased for all infants during the study period, there was no causal relationship between states' prioritization of safe infant sleep and SSP improvement. More targeted approaches may be needed to reduce the racial/ethnic disparity in SSP and reduce the risk for sleep-associated infant death. KEY POINTS: · Supine sleep positioning improved for Black and White infants in the U.S.. · State prioritization of safe infant sleep did not directly impact SSP for NHB or NHW infants.. · More targeted approaches may be needed to reduce racial/ethnic disparities in safe sleep practices.

Racial and Ethnic Disparities in Medical Complexity and In-Hospital Death Among US-Born VLBW Infants.

BACKGROUND AND OBJECTIVE: To assess the racial and ethnic disparity in the prevalence of complex chronic conditions (CCC) and/or in-hospital death among US-born very low birth weight (VLBW, <1500 g) infants. METHODS: This retrospective, cross-sectional analysis of discharge data from the Kids' Inpatient Database, included VLBW infants born in US hospitals in 2009 and 2012 (n = 554825, weighted n = 573693) exlcuding those with missing demographics. The main outcome was CCC or death. Multiple logistic regression modeling estimated the association of various characteristics with CCC or death, considering race and ethnicity. RESULTS: There was heterogeneity in the association of insurance status and hospital region and experiencing CCC or death when compared across races and ethnicities. Infants of all races and ethnicities had higher odds of CCC or death if they had an operative procedure, were outborn, or had a birth weight of <500 g or 500 g to 999 g compared with 1000 g to 1499 g. Non-Hispanic Black infants <500 g, however, had the highest odds of CCC or death compared with those 1000 g to 1499 g (adjusted odds ratio 67.2, 95% confidence interval, 48.6-93.0), 2.3 times higher than the odds for non-Hispanic White infants (AOR 2.32, 95% confidence interval, 1.57-3.42). CONCLUSIONS: Insurance and region were associated with increased prevalence of CCC or death in certain racial and ethnic groups. Additionally, non-Hispanic Black infants <500 g had >2.3 times the odds of CCC or death compared with non-Hispanic White infants, relative to infants 1000 g to 1499 g. Additional investigation is needed to understand the drivers of these disparities.

Cerebrospinal fluid amino acids glycine, serine, and threonine in nonketotic hyperglycinemia.

Nonketotic hyperglycinemia (NKH) is caused by deficient glycine cleavage enzyme activity and characterized by elevated brain glycine. Metabolism of glycine is connected enzymatically to serine through serine hydroxymethyltransferase and shares transporters with serine and threonine. We aimed to evaluate changes in serine and threonine in NKH patients, and relate this to clinical outcome severity. Age-related reference values were developed for cerebrospinal fluid (CSF) serine and threonine from 274 controls, and in a cross-sectional study compared to 61 genetically proven NKH patients, categorized according to outcome. CSF d-serine and l-serine levels were stereoselectively determined in seven NKH patients and compared to 29 age-matched controls. In addition to elevated CSF glycine, NKH patients had significantly decreased levels of CSF serine and increased levels of CSF threonine, even after age-adjustment. The CSF serine/threonine ratio discriminated between NKH patients and controls. The CSF glycine/serine aided in discrimination between severe and attenuated neonates with NKH. Over all ages, the CSF glycine, serine and threonine had moderate to fair correlation with outcome classes. After age-adjustment, only the CSF glycine level provided good discrimination between outcome classes. In untreated patients, d-serine was more reduced than l-serine, with a decreased d/l-serine ratio, indicating a specific impact on d-serine metabolism. We conclude that in NKH the elevation of glycine is accompanied by changes in l-serine, d-serine and threonine, likely reflecting a perturbation of the serine shuttle and metabolism, and of one-carbon metabolism. This provides additional guidance on diagnosis and prognosis, and opens new therapeutic avenues to be explored.

A Retrospective Review of Opioid Prescribing Practices for At-Risk Pediatric Populations Undergoing Ambulatory Surgery.

OBJECTIVE: Pediatric patients with sleep-disordered breathing (SDB) and obesity are at risk for opioid-induced respiratory depression. Although monitoring in the inpatient setting allows for early recognition of opioid-related adverse events, there is far less vigilance after ambulatory surgery as patients are discharged home. Guidelines for proper opioid dosing in these pediatric subsets have not been established. We sought to determine if at-risk children were more likely to receive doses of opioids outside the recommended range. METHODS: Baseline opioid prescribing data for all outpatient surgery patients receiving an opioid prescription between January 2019 and June 2020 were retrospectively reviewed. Patients with SDB or obesity were identified. To obtain more information about prescribing practices, we analyzed patient demographics, size descriptors used for calculations, and prescription characteristics (dose, duration, and prescribing surgical service). RESULTS: A total of 4674 patients received an opioid prescription after outpatient surgery. Of those, 173 patients had SDB and 128 were obese. Surgical subspecialties rendering most of the opioid prescriptions included otolaryngology and orthopedics. Obese patients were more likely (64%) to be prescribed opioids using ideal weight at higher mg/kg doses (>0.05 mg/kg; 83.3%; p < 0.0001). When providers used actual body weight, lower mg/kg doses were more likely to be used (53.7%; p < 0.0001). No prescriptions used lean body mass. CONCLUSIONS: Overweight/obese children were more likely to receive opioid doses outside the recommended range. Variability in prescribing patterns demonstrates the need for more detailed guidelines to minimize the risk of opioid-induced respiratory complications in vulnerable pediatric populations.

Quality and Safety Analysis of 2,999 Telemedicine Encounters During the COVID-19 Pandemic.

OBJECTIVE: To examine whether telemedicine remains safe and of high quality despite rapid expansion of services by comparing telemedicine encounters before and during the COVID-19 pandemic. METHODS: Pre-post study investigating 2,999 telemedicine encounters: February 1, 2020-May 15, 2020, was performed. A total of 2,919 completed visits before and after strict social distancing implementation were analyzed for patient and provider characteristics, encounter characteristics (e.g., history and physical examination), and quality and safety metrics (phone calls ≤ 7 days postvisit, visit-cause-specific hospital admission or mortality ≤ 30 days after visit). Stratified analysis of 3 groups for outcomes (young age, neuromuscular diagnosis, and new encounters) was performed. RESULTS: Patients ranging from 1 month to 33 years of age were seen. Rural patients were less likely to be seen during the pandemic compared with urban patients (8% vs 90%; p < 0.0001); teaching clinic and specialty clinic encounters increased significantly during the pandemic (8% vs 3%; p = 0.005), and documentation of at least 2 systems on examination was noted significantly more frequently during the pandemic (13% vs 7%; p = 0.009). No deaths were reported. There were no differences before/during the pandemic in safety or telemedicine failure metrics within the entire group and high-risk subgroups. CONCLUSIONS: Despite a markedly and rapidly expanded scope of ambulatory telemedicine care during the COVID-19 pandemic, telemedicine remained a safe and high-quality option for pediatric neurology patients. In addition, populations perceived as high risk for telemedicine (the very young, new patients, and those with neuromuscular diagnoses) can benefit from telemedicine visits, particularly when access to in-person care is limited.

Prevalence and Predictors of Medical Complexity in a National Sample of VLBW Infants.

BACKGROUND AND OBJECTIVES: Very low birth weight (VLBW) infants are at high risk for morbidities beyond the neonatal period and ongoing use of health care. Specific morbidities have been studied; however, a comprehensive landscape of medical complexity in VLBW infants has not been fully described. We sought to (1) describe the prevalence of complex chronic conditions (CCCs) and (2) determine the association of demographic, hospital, and clinical factors with CCCs and CCCs or death. METHODS: This retrospective cross-sectional analysis of discharge data from the Kids' Inpatient Database (2009-2012) included infants with a birth weight <1500 g and complete demographics. Outcomes included having CCCs or having either CCCs or dying. Analyses were weighted; univariate and multiple logistic regression models were used to estimate unadjusted and adjusted odds ratios. A dominance analysis with Cox-Snell R 2 determined the relative contribution of demographic, hospital, and clinical factors to the outcomes. RESULTS: Among our weighted cohort of >78 000 VLBW infants, >50% had CCCs or died. After adjustments, the prevalence of CCCs or CCCs or death differed by sex, race and ethnicity, hospital location, US region, receipt of surgery, transfer status, and birth weight. Clinical factors accounted for the highest proportion of the model's ability to predict CCCs and CCCs or death at 93.3% and 96.3%, respectively, whereas demographic factors were 11.5% and 2.3% and hospital factors were 5.2% and 1.4%, respectively. CONCLUSIONS: In this nationally representative analysis, medical complexity is high among VLBW infants. Varying contributions of demographic, hospital, and clinical factors in predicting medical complexity offer opportunities to investigate future interventions to improve care delivery and patient outcomes.

Persistent Racial/Ethnic Disparities in Supine Sleep Positioning among US Preterm Infants, 2000-2015.

OBJECTIVE: To assess trends in racial disparity in supine sleep positioning (SSP) across racial/ethnic groups of infants born early preterm (Early preterm; <34 weeks) and late preterm (Late preterm; 34-36 weeks) from 2000 to 2015. STUDY DESIGN: We analyzed Pregnancy Risk Assessment Monitoring System data (a population-based perinatal surveillance system) from 16 US states from 2000 to 2015 (Weighted N = 1 020 986). Marginal prevalence of SSP by year was estimated for infants who were early preterm and late preterm, adjusting for maternal and infant characteristics. After stratifying infants who were early preterm and late preterm, we compared the aOR of SSP trends across racial/ethnic groups by testing the time-race interaction. RESULTS: From 2000 to 2015, Non-Hispanic Black infants had lower odds of SSP compared with Non-Hispanic White infants for early preterm (aOR 0.61; 95% CI 0.47-0.78) and late preterm (aOR 0.44; 95% CI 0.34-0.56) groups. For Hispanic infants, there was no statistically significant difference for either preterm group when compared with Non-Hispanic White infants. aOR of SSP increased (on average) annually by 10.0%, 7.3%, and 7.7%, respectively, in Non-Hispanic White, Non-Hispanic Black, and Hispanic early preterm infants and by 5.8%, 5.9%, and 4.8% among Non-Hispanic White, Non-Hispanic Black, and Hispanic late preterm infants. However, there were no significant between-group differences in annual changes (Early preterm: P = .11; Late preterm: P = .25). CONCLUSIONS: SSP increased for all racial/ethnic preterm groups from 2000 to 2015. However, the racial/ethnic disparity in SSP among early preterm and late preterm groups persists.
