The impact of a biocellulose-based repair of fetal open spina bifida on the need to untether the cord: is it time to unify techniques for prenatal repair?

To report the need for cord untethering after prenatal repair of open spina bifida using a unique biocellulose-based technique performed at a later gestational age. An observational cohort study was conducted to determine the incidence of tethered cord syndrome. Between May 2013 and May 2022, we performed 172 procedures using the percutaneous fetoscopic approach in fetuses at 26-28 weeks of gestation. After placode dissection, a biocellulose patch was placed to cover the placode, a myofascial flap (when possible) was dissected, and the skin was closed. Owing to death or loss to follow-up, 23 cases were excluded. Cord tethering syndrome was defined as symptoms of medullary stretching, and the infants were evaluated and operated on by local neurosurgeons after an magnetic resonance imaging examination. Infants over 30-month had ambulation and neurodevelopment evaluations (PEDI scale). Among 172 cases operated at a median gestational age of 26.7 weeks and delivered at 33.2 weeks, 149 cases were available for postnatal follow-up, and cord untethering was needed in 4.4% of cases (6/136; excluding 13 cases younger than 12 months). Cerebrospinal fluid diversion and bladder catheterization were needed in 38% and 36% of cases, respectively. Of the 78 cases evaluated at 30 months, 49% were ambulating independently, and 94% had normal social function. The biocellulose-based technique was associated with a low rate of cord tethering, wich may be attributed to the lack of the duramater suture during prenatal repair, the formation of a neoduramater and/or later gestational age of surgery.

Exploring the neurological features of individuals with germline PTEN variants: A multicenter study.

PTEN, a known tumor suppressor gene, is a mediator of neurodevelopment. Individuals with germline pathogenic variants in the PTEN gene, molecularly defined as PTEN hamartoma tumor syndrome (PHTS), experience a variety of neurological and neuropsychiatric challenges during childhood, including autism spectrum disorder (ASD). However, the frequency and nature of seizures and the utilization of allied health services have not been described. Young patients with PHTS and sibling controls were recruited across five centers in the United States and followed every 6-12 months for a mean of 2.1 years. In addition to the history obtained from caregivers, neurodevelopmental evaluations and structured dysmorphology examinations were conducted, and brain MRI findings, received therapies, and epilepsy characteristics were reported. One hundred and seven patients with PHTS (median age 8.7 years; range 3-21 years) and 38 controls were enrolled. ASD and epilepsy were frequent among patients with PHTS (51% and 15%, respectively), with generalized epilepsy strongly associated with ASD. Patients with epilepsy often required two antiseizure medications. Neuroimaging revealed prominent perivascular spaces and decreased peritrigonal myelination in individuals with PHTS-ASD. Allied therapy use was frequent and involved physical, occupational, speech, and social skills therapies, with 89% of all patients with PHTS, regardless of ASD diagnosis, utilizing at least one service. This prospective, longitudinal study highlights the wide neurological spectrum seen in young individuals with PHTS. ASD is common in PHTS, comorbid with epilepsy, and allied health services are used universally. Our findings inform care discussions with families about neurological outcomes in PHTS.

Developmental outcomes of preschool children requiring craniosynostosis surgery in Manitoba: a cohort study

Abstract Craniosynostosis is a congenital abnormality resulting in the premature fusion of one or more cranial sutures and usually requires surgical correction in the first year of life. While the majority of craniosynostosis cases represent isolated, nonsyndromic defects, approximately 25% are linked to a genetic diagnosis. Craniosynostosis has been associated with developmental delay. Therefore, historically in Manitoba, all children with surgically managed craniosynostosis were referred to the Child Development Clinic (CDC) for developmental assessment. There are currently prolonged wait times for neurodevelopmental assessments at CDC, leading to the need to better prioritize children who require neurodevelopmental assessment. The aim of the study was then to determine the developmental outcomes of preschool children requiring craniosynostosis surgery in Manitoba from July 1, 2016 through December 1, 2021. In this retrospective cohort study, clinical records were reviewed to evaluate the developmental outcomes of patients who were assessed at CDC for surgically managed craniosynostosis. Out of 67 children included in this study, 18% demonstrated global developmental delay, 24% demonstrated mild developmental delay, and 58% were developmentally appropriate across all levels. The presence of a genetic syndrome, multisutural craniosynostosis, and parental socioeconomic status were associated with risk of global developmental delay. The findings of this study suggest that while not all children with craniosynostosis present with developmental delay, those with suspected or confirmed syndromic involvement, multisutural cranyosinostosis, and/or low SES, should be referred for neurodevelopmental evaluation.

Neurodevelopmental evaluation of children who were operated due to congenital anomaly with the ‘Ages and Stages Questionnaire (ASQ)’ and ‘ASQ: Social–Emotional’

BackgroundThe purpose of surgeries performed for congenital anomalies in children is to increase the survival rates and provide a developmental comparison to that of their peers.AimThe objective of this study was to investigate the development of children following surgery for congenital anomalies and the risk factors affecting their development.MethodsOur study included 33 children who underwent surgery for gastrointestinal anomalies in our clinic between 2011 and 2016, and did not have any syndrome, chromosomal abnormality, or additional abnormality. Developmental levels were evaluated using the Ages and Stages Questionnaire (ASQ) and the ASQ: Social–Emotional (ASQ: SE) scales adapted for the use on Turkish children. Data on patient history were obtained retrospectively from patient files.ResultsThe study included 33 patients, including 11 with esophageal atresia, 6 with intestinal atresia, 11 with anorectal malformation, and 5 with Hirschsprung's disease. Developmental delay was found in the ASQ of 72.7% of the patients and the ASQ: SE tool was 27% of the patients. The rate of patients with scores below the threshold from each parameter of ASQ was higher than that of the normal population (p < 0.05). Development delay was detected using the ASQ scale in 100% of those with microcephaly at birth, in 91% of premature infants born between 1500 and 2500 g, and in 83.3% of those with low birth weight to gestational age.ConclusionsIn children who underwent surgery due to congenital anomalies, an evaluation through developmental tests, a post-surgical follow-up process, and a referral to the relevant disciplines when necessary may increase the success of surgery as well as increase the life quality of the patient.

Semi-Automatic Analysis of Specific Electroencephalographic Patterns during NREM2 Sleep in a Pediatric Population after SARS-CoV-2 Infection.

The post-COVID-19 condition is defined by the World Health Organization as the persistence of symptoms or development of new symptoms three months after the initial SARS-CoV-2 infection, lasting for at least two months without a clear explanation. Neuropsychiatric disorders associated with this condition include asthenia, memory and concentration problems, and sleep disturbances. Our study aims to investigate sleep patterns following SARS-CoV-2 infection using EEG findings and a sleep quality questionnaire completed by parents (Sleep Disturbance Scale for Children-SDSC). Notably, our investigation is based on a convenience sample. The patients in our sample, aged 1 to 14 years, are not currently taking any medications; rather, they are undergoing follow-up assessments at the Child Neuropsychiatry department of the University Hospital of Messina for neurodevelopmental evaluations. Specifically, we are analyzing amplitude and power spectrum data in the first five minutes of NREM2 sleep, calculated from EEG recordings obtained via bipolar leads within three months after the onset of the disease. These results will be compared with controls performed on the same subjects in the six months preceding the infection. The focus of the study was sleep spindles, which are generated by the thalamocortical systems and play a role in sleep modulation, memory, and learning. Preliminary analysis suggests a predominant increase in the slow component of the spindles in the right-frontal lead.

Neurodevelopmental evaluation of newborns who underwent hypothermia with a diagnosis of hypoxic ischemic encephalopathy based on the Bayley-III scale.

Hypoxic ischemic encephalopathy (HIE) is one of the common causes of mortality and morbidity in newborns. Despite therapeutic hypothermia, an important treatment with proven efficacy, the morbidity and mortality rates remain high. The aim of this study was to neurodevelopmentally evaluate patients who underwent therapeutic hypothermia. Included herein were patients who underwent hypothermia between 2018 and 2020. Their medical files were reviewed retrospectively, and their demographic and clinical information was recorded. Patients whose contact information was available were called to the developmental pediatrics outpatient clinic for a neurodevelopmental evaluation. The Bayley Scales of Infant and Toddler Development 3rd Edition (Bayley-III) was used as the evaluation tool. Laboratory values and clinical parameters of the patients were further analyzed. It was found that 42 patients underwent hypothermia in 3 years, of whom 14 (33.3%) had died. Of the 28 patients who were discharged, 20 children could be reached, and a neurodevelopmental evaluation was performed. Developmental delay in the cognitive area was detected in 11 (55%) patients, delay in the language area was found in 9 (45%) patients, and delay in the motor area was found in 11 (55%) patients. The correlation and regression analysis results determined that the time to start cooling was the most effective common factor in all 3 fields of scoring. The time to start cooling is related to the neurodevelopmental outcomes of patients with HIE. The earlier cooling is started, the better the neurodevelopmental results. Despite therapeutic hypothermia, the neurodevelopmental development of infants may be adversely affected. These patients should be followed-up neurodevelopmentally for a long time.

39 Neurodevelopmental Complexity of a Patient with Perinatal Right Middle Cerebral Artery Stroke and Infantile Spasms

Objective:A rich literature exists on cognitive changes related to focal injury in the adult brain. In contrast, the developing brains of children are less understood. In contrast to adult cases, 20% to 25% of perinatal strokes result in language disorder regardless of lesion lateralization. Existing literature suggests children with perinatal stroke may present with a range of executive functioning and visuospatial processing difficulties. Gross and fine motor challenges are also likely to occur. Furthermore, these children have an increased prevalence of autism spectrum disorder (ASD) and carry the highest risk for epilepsy. Despite growing research on neurodevelopmental profiles in patients with perinatal stroke, published literature is limited.Participants and Methods:Our study examines neurodevelopment of a 2-year-old, right-handed male with a history of perinatal ischemic right middle cerebral artery (MCA) stroke, infantile spasms, and left hemiparesis following right hemispherectomy for seizure management who underwent two neurodevelopmental evaluations at our medical center over approximately 3 years.Results:Findings from the patient’s evaluation with the Mullen Scales of Early Learning revealed overall cognitive ability in the low average range (SS = 89, 23rd percentile); however, notable variability was seen in his performance. His receptive language was average (SS = 98, 45th %tile) and consistent with previous evaluation results, and he has made gains in visual reception (from SS = 75, 5th %tile to SS = 91, 27th %tile) and expressive language (from SS = 55, 0.1st %tile to SS = 70, 2nd %tile). In addition, his gross motor was exceptionally low (SS = 55, 0.1st %tile) and consistent with previous evaluation results. Fine motor was low average (SS = 84, 14th %tile).Conclusions:Our patient showed cognitive gains in language and visual reception since his prior evaluation despite history of right MCA stroke and right hemispherectomy. Improvements are likely due to a combination of early brain plasticity and intensive therapies he has received. Consistent with published findings in this population, he experienced seizures associated with his stroke. Our results add to the limited literature on neurodevelopmental challenges associated with perinatal stroke and progress that can be made when appropriate supports are provided early and consistently.

H - 60 Navigating Cultural and Medical Factors in Pediatric Neuropsychological Assessment: a Case Study.

The current case study focuses on a neurodevelopmental evaluation for a child with a complex medical history, suspected genetic disorder, and significant developmental delays within the context of cultural diversity, linguistic barriers, and interpretation services. Patient is a 4-year-old male of Oromo decent who is exposed to both Oromo and English. Medical background is significant for congenital glaucoma and global developmental delay. He is nonverbal and uses few gestures to communicate. He presented with spastic motor movements and dysmorphic facial features. There is no history of genetic testing nor consults with neurology. Developmentally appropriate measure of neurocognitive functioning was administered with the use of an Oromo interpreter. Results revealed impaired performance within the areas of cognition, language, and motor functioning. Cognitive abilities measured similar to a 26-month-old. The patient's social communication and emotional reciprocity varied; there was consideration of an autism spectrum disorder. Diagnostic challenges included medical complexity (i.e., vision differences with eye contact and visual referencing, motor functioning), unanswered diagnostic questions (i.e., underlying genetic or neurological condition), and cultural considerations. The evaluation yielded diagnoses of a global developmental delay and unspecified neurodevelopmental disorder. Recommendations included referrals to neurology, genetics, care coordination, and outpatient therapies. Given the complexity of phenotypical behavioral manifestations of genetic disorders and cultural differences in terms of appropriate social behaviors convolute behaviors observed during the evaluation. The case study brings to light the consideration of cultural differences when interpreting behaviors as well as the value of a multidisciplinary approach to neuropsychological evaluation for diagnostic clarification.

20 Developmental Outcomes of a Cohort of Preschool Children Requiring Craniosynostosis Surgery in Manitoba

Abstract Background Historically in Manitoba, all children with craniosynostosis were referred to the Child Development Clinic (CDC) for neurodevelopmental evaluation, because craniosynostosis has been associated with developmental delay. However, due to heightened volume pressures, the CDC recently decided to limit the number of referrals accepted for evaluation of children with craniosynostosis. Objectives To inform best practices for neurodevelopmental screening, this study aims to describe the developmental outcomes of preschool children requiring craniosynostosis surgery in Manitoba. Design/Methods In this historical chart review of the CDC electronic medical record, the developmental outcomes of patients who were assessed at CDC for surgically managed craniosynostosis between July 1st, 2016 and December 1st, 2021 were described. Developmental quotients across Motor, Cognitive and Language domains were collected, and patients were categorized as Normal, Mild Delay in 1 Area or Delay in ≥2 Areas. Demographic and medical characteristics were collected, and descriptive statistics were used to describe and compare outcomes between groups. Results Out of a total of 67 children, 18% (n=12) demonstrated developmental delays in ≥2 areas, 23.9% (n=16) demonstrated mild developmental delays in one area, and 58.2% (n=39) were developmentally appropriate across all areas. Presence of genetic syndrome (p&amp;lt;0.001), suture type (p=0.011), and parental SES score (p=0.028) were significantly associated with developmental delay in ≥2 areas. Odds ratios for genetic syndrome and SES score were 218.352 (95% CI 6.843, 6967.766) and 0.857 (95% CI 0.766, 0.959) respectively. 11.9% (n=8) of children were referred to Children’s Disability Services, 5 of whom had syndrome involvement. Conclusion To target children at highest risk for developmental delay, we suggest that children with craniosynostosis be referred for neurodevelopmental evaluation if they have multisutural craniosynostosis, suspicion or confirmed genetic syndrome, or an identified developmental concern by primary care physician screening.

Trends in Preterm Body Composition and Neurodevelopmental Outcomes after Discharge

Introduction: Body composition, specifically fat-free mass (FFM), of preterm infants is associated with improved neurodevelopmental outcomes. Little is known about body composition of preterm infants after discharge. Preterm body composition was measured by air displacement plethysmography (ADP) at two time points, inpatient (35–40 weeks postmenstrual age [PMA]) and outpatient (48–58 weeks PMA), with neonatal factors and neurodevelopmental testing at 4–6 months corrected age. We hypothesized increased FFM is positively associated with neurodevelopment. Methods: From 2007 to 2011, 510 infants admitted to the Medical University of South Carolina’s neonatal intensive care unit underwent ADP. A total of 379 of 510 (74%) had anthropometrics at birth, an ADP scan with FFM, fat mass, fat percent z-scores, and an outpatient neurodevelopmental evaluation (CAT/CLAMS, Peabody Gross Motor). Variables were compared using multivariate analyses for body composition measurements. Results: The infants were 32 ± 4.8 weeks gestational age at birth with an average birth weight of 1,697 ± 932 g. Most (56%) infants received maternal milk at discharge. CAT, CLAMS, and gross motor scores had positive correlations with FFM z-scores at inpatient and outpatient ADP (p < 0.05). Receiving maternal milk at discharge was positively associated with cognitive (β = 0.22, p < 0.05) and language scores (β = 0.26, p < 0.05). Conclusion: Increased FFM is associated with improved cognitive, language, and gross motor testing. Maternal milk was positively associated with language and cognitive scores.

Predictors of poor neurodevelopmental outcomes of very preterm and very low birth weight infants.

Despite recent improvements, premature infants remain at high risk for long-term morbidity and poorer neurodevelopment, particularly very preterm (VP) and very low birth weight (VLBW). The aim of this study was to describe neurodevelopmental outcomes at two years and identify potential predictors of worse performance. In a retrospective cohort, a two-years' neurodevelopmental evaluation was analyzed. Multivariable regressions were used to study the association of perinatal history with neurodevelopmental outcomes. Subjects included VP and/or VLBW born at a Portuguese III-level perinatal center between 2011-2017. Milestones outcomes were assessed using the Griffiths' Mental Development Scales. One hundred seventy-seven infants were included. Two-years milestones were not achieved in 18.6% in language domain and 7.3% in motor function, 4.5% wore glasses and 1.1% auditory prosthesis/cochlear implant. Almost 30% needed intervention, 18.6% occupational therapy, 16.4% physiotherapy and 13.6% speech therapy. Griffiths' Mental Development Scales was performed in 139, with a mean global quotient of 98.3 and hearing/speech as the least quoted scale. Global development delay (GDD) was present in 14.8% and cerebral palsy in 2.8%. Multivariate analysis by logistic regression adjusted to gestational age, birth weight and confounding variables, revealed a statistically significant association between GDD and hydrocephalus with shunt/reservoir (OR:19.01), retinopathy of prematurity stage ≥2 (OR:7.86) and neonatal sepsis (OR:3.34). Consistent with recent studies, preterm are at increased risk of neurodevelopmental impairment, mainly due to GDD and language delay, rather than cerebral palsy. In this population, hydrocephalus, retinopathy of prematurity and neonatal sepsis were strongly associated with poorer outcomes. Insight into these factors is essential to refer patients for specific early intervention programs.

Impact of Residual Lesion Severity on Neurodevelopmental Outcomes Following Congenital Heart Surgery in Infancy and Childhood.

Children with congenital heart disease are at increased risk of neurodevelopmental delay throughout their lifespan. This risk is exacerbated following congenital heart surgery (CHS) in infancy. However, there are few modifiable risk factors for postoperative neurodevelopmental delay. In this study, weassessed the Residual Lesion Score (RLS), a quality assessment metric that evaluates residual lesion severity following CHS, as a predictor of neurodevelopmental delay. This was a single-center, retrospective review of patients who underwent CHS from 01/2011 to 03/2021 and post-discharge neurodevelopmental evaluation from 12 to 42months of age using the Bayley Scales of Infant Development, 3rd Edition (BSID-III). RLS was assigned per published criteria: RLS 1, no residua; RLS 2, minor residua; and RLS 3, major residua or pre-discharge reintervention. Associations between RLS and BSID-III scores, as well as trends in neurodevelopmental outcomes over time, were evaluated. Of 517 patients with median age at neurodevelopmental testing of 20.0 (IQR 18.0-22.7) months, 304 (58.8%), 146 (28.2%), and 67 (13.0%) were RLS 1, 2, and 3, respectively. RLS 3 patients had significantly lower scaled scores in the cognitive, receptive, and expressive communication, and fine and gross motor domains, compared with RLS 1 patients. Multivariable models accounted for 21.5%-31.5% of the variation in the scaled scores, with RLS explaining 1.4-7.3% of the variation. In a subgroup analysis, RLS 3 patients demonstrated relatively fewer gains in cognitive, expressive communication, and gross motor scores over time (all p < 0.05). In conclusion,RLS 3 patients are at increased risk for neurodevelopmental delay, warranting closer follow-up and greater developmental support for cognitive, language, and motor skills soon after surgery.

Treatment Approaches for Swallowing Disorders in Children.

A swallowing disorder or dysphagia is defined as a disorder in the sequence of swallowing, during the oral or pharyngeal phase, which compromises the safety and/or efficiency of transit of the food bolus to the esophagus. The evaluation of neurodevelopment, nutrition, and preventive medicine actions are as important as the clinical evaluation of dysphagia, so they must be included and systematized in all pediatric evaluations; This evaluation can be divided into different parts: bedside swallowing evaluation, instrumental swallowing evaluation, and additional studies. The management of swallowing disorders requires a multidisciplinary team approach, depending on the child's age, cognitive and physical abilities, and the specific swallowing and feeding disorder, ensuring adequate and safe nutrition and improving the patient's quality of life.

Assessment of Mastery Motivation and Neurodevelopment of Young Children at High Risk for Developmental Delays.

Young children's mastery motivation and neurodevelopmental evaluation can contribute to overall early assessment for early intervention evaluation. At present, children born preterm (<37 weeks gestation) and with a low birth weight (LBW; <2500 g) are at increased risk of experiencing developmental delays and more nuanced cognitive and language challenges. The main objective of this exploratory study was to examine the connection between preterm children's mastery motivation and their neurodevelopment, as well as to determine whether assessing mastery motivation can enhance assessment practices for early intervention (EI) programs. Parents of children born preterm completed the revised Dimensions of Mastery Motivation Questionnaire (DMQ18). Neurodevelopment was measured on the Bayley Scales of Infant and Toddler Development (BSID-III). Results revealed significant correlations between DMQ18 and BSID-III measures. Multivariate analysis showed that infants and toddlers born with a very low birth weight (VLBW; <1500 g) scored significantly lower on the infant DMQ18 and the BSID-III measures. Regression analyses revealed that birth weight and home environment were significant predictors of the children's eligibility for EI programs. Infants' social persistence with other children, gross motor persistence, and mastery pleasure, as well as toddlers' objective cognitive persistence, social persistence with adults, gross motor persistence, mastery pleasure, and negative reaction to frustration, were important markers for evidenced-based practices in EI programs. This study demonstrates the utility of the DMQ18 as a contributory assessment measure and the importance of birth weight and home environment in predicting EI enrollment.

Neurodevelopmental Outcomes and Brain Volumetric Analysis of Low-Grade Intraventricular Hemorrhage

Purpose: Extremely preterm infants are prone to brain injury and underdevelopment. Intraventricular hemorrhage (IVH) is the most common cause of brain injury and a significant risk factor for neurodevelopmental delay in preterm infants. Severe IVH is known to have a poor outcome; however, the outcomes of low-grade IVH remain controversial. This study aimed to evaluate neurodevelopmental outcomes and brain segmental volumes of preterm infants with low-grade IVH.Methods: This retrospective cohort study included 109 extremely preterm infants who underwent term equivalent age-magnetic resonance imaging and neurodevelopmental evaluation at a corrected age of 18 to 24 months. We compared infants with and without low-grade IVH.Results: Among the 109 extremely preterm infants, 25 had low-grade IVH and 84 had no IVH. There were no significant differences in the neurodevelopmental outcomes between the low-grade and no IVH groups. In multivariate analysis, low-grade IVH was associated with a smaller medullary volume (adjusted odds ratio, 0.575; 95% confidence interval, 0.346 to 0.957; &lt;i&gt;P&lt;/i&gt;=0.034).Conclusion: We found no significant differences in the neurodevelopmental outcomes of extremely preterm infants at a corrected age of 18 to 24 months between those with low-grade IVH and those without IVH. Low-grade IVH was associated with a smaller medullary volume.

Natural history and mid-term neurodevelopmental outcome of fetuses with isolated mild ventriculomegaly diagnosed in the second half of pregnancy

Introduction Prenatal diagnosis and counseling of isolated ventriculomegaly (VM) represent a considerable challenge. We aimed to analyze the intrauterine evolution, associated anomalies, and neurodevelopmental outcome using the Battelle Development Inventory (BDI) of fetuses with an initial diagnosis of isolated mild VM. Material and methods Retrospective cohort study of fetuses diagnosed with mild isolated VM (10 -12 mm) between 2012 and 2016 in a tertiary hospital. In 2018, parents were invited to complete the structured BDI test for the neurodevelopmental evaluation of their children in five domains (personal-social skills, adaptive behavior, psychomotor ability, communication, and cognition). Results exceeding two standard deviations were considered abnormal and referred to an expert neuropediatrician. Results We identified 43 cases of mild isolated VM. In 5 (11%), structural abnormalities were detected during prenatal follow-up, being related to non-regressive forms (p = .01) and bilateral VM (p = .04). The BDI test was completed by 19/43 (44%). The global score was abnormal in 10/19 (53%). Of them, the neuropediatrician confirmed a neurodevelopmental delay solely in 3 cases that had already been diagnosed with neurological disorders. The most affected domains were gross motor skills (63%), personal-social (63%), and adaptive domains (47%). Communicative and cognitive areas were abnormal in 26% of cases. Conclusion In fetuses with isolated mild VM detected in the second half of pregnancy, 53% had an abnormal BDI test at 2–6 years, but a neurological disorder was only confirmed in the 30% of them.

Developmentally-Trained Primary Care Clinicians: A Pipeline to Improved Access?

The purpose of this study is to decrease wait time and improve access to developmental-behavioral pediatric (DBP) evaluation in children 4 years of age and younger as part of a quality improvement (QI) initiative in an urban safety-net hospital. A primary care pediatrician received DBP minifellowship training 6 hours per week for 1 year to become a developmentally-trained primary care clinician (DT-PCC). DT-PCCs then conducted developmental evaluations that consisted of using a Childhood Autism Rating Scale and Brief Observation of Symptoms of Autism to evaluate children 4 years and younger referred within the practice. Baseline standard practice involved a 3-visit model: DBP advanced practice clinician (DBP-APC) intake visit, neurodevelopmental evaluation by a developmental-behavioral pediatrician (DBP), and feedback by a developmental-behavioral pediatrician. Two QI cycles were completed to streamline the referral and evaluation process. Seventy patients with a mean age of 29.5 months were seen. The average days to initial developmental assessment decreased from 135.3 days to 67.9 days with a streamlined referral to the DT-PCC. Of the 43 patients who required further evaluation by a DBP, the average days to developmental assessment reduced from 290.1 to 120.4 days. Developmentally-trained primary care clinicians allowed for earlier access to developmental evaluations. Further research should explore how DT-PCCs can improve access to care and treatment for children with developmental delays.

Development of the data registry for the Cardiac Neurodevelopmental Outcome Collaborative.

Children with congenital heart disease (CHD) can face neurodevelopmental, psychological, and behavioural difficulties beginning in infancy and continuing through adulthood. Despite overall improvements in medical care and a growing focus on neurodevelopmental screening and evaluation in recent years, neurodevelopmental disabilities, delays, and deficits remain a concern. The Cardiac Neurodevelopmental Outcome Collaborative was founded in 2016 with the goal of improving neurodevelopmental outcomes for individuals with CHD and pediatric heart disease. This paper describes the establishment of a centralised clinical data registry to standardize data collection across member institutions of the Cardiac Neurodevelopmental Outcome Collaborative. The goal of this registry is to foster collaboration for large, multi-centre research and quality improvement initiatives that will benefit individuals and families with CHD and improve their quality of life. We describe the components of the registry, initial research projects proposed using data from the registry, and lessons learned in the development of the registry.
