The Use of POCUS to Identify Subgaleal Fluid Collections and Intracranial Infections.

Point-of-care ultrasound (POCUS) has been useful in describing soft tissue infections, such as cellulitis and abscesses. There has been limited use of ultrasound to describe findings of intracranial infections, such as Pott's puffy tumor, in cases of forehead prominence and signs of infection. In this case series we present POCUS findings in 2 cases of intracranial infections and one case of soft tissue edema without intracranial involvement from a single pediatric tertiary care center. Ultrasound findings revealed subgaleal fluid collections with associated periosteal lifting of the frontal bone in cases of Pott's Puffy tumor and intracranial infection, but no bony disruption or periosteal lifting in the patient with traumatic soft tissue edema. As pediatric intracranial infections may continue to have uncharacteristic seasonal peaks, POCUS may be considered as a first-line imaging technique for patients presenting with forehead swelling for differentiating infectious and traumatic etiologies as well as judging the need for further imaging techniques such as computed tomography and magnetic resonance imaging.

Incidence of adverse events related to intravenous immunoglobulin therapy in children.

Intravenous immunoglobulin (IVIG) therapy is used in the treatment of pediatric diseases, although data about IVIG-related adverse events (IVIG-AEs) are limited. Objectives of this study were to document the incidence of IVIG-AEs in pediatric hospitalized patients and to identify risk factors for IVIG-AEs. This retrospective cohort study included patients <18 years old who received IVIG therapy while admitted at a Canadian pediatric tertiary care center between 2016 and 2020. Patients and IVIG-perfusions characteristics were collected, as well as IVIG-AEs. Bivariate and multivariable logistic regressions were used to explore predictors of IVIG-AEs. We included 228 children, totaling 478 IVIG perfusions. Indications included treatment for inflammatory (52.6%), autoimmune disorders (35.5%), and immunoglobulin replacement (11.8%). A total of 213 IVIG-AEs were reported. Fever (13.6%) and headache (6.7%) were the most frequent IVIG-AEs. Most IVIG-AEs were mild (57%) or moderate (31%) in severity, but 12% were severe reactions. The following factors were predictive of IVIG-AEs in univariate analyses: older age (OR 1.14 [95% CI: 1.07-1.21]), dehydration (OR 2.55 [95% CI: 1.43-4.55]), concurrent allergies (OR 2.87 [95% CI: 1.26-6.56]), first perfusion (OR 1.53 [95% CI: 1.02-2.30]), and higher dosage (OR 2.14 [95% CI: 1.39-3.33]). Concurrent steroids decreased the risk of IVIG-AEs (OR 0.43 [95% CI: 0.19-0.96]). Older age and higher IVIG dose remained independent predictors of IVIG-AEs in multivariable analyses. Mild IVIG-AEs are frequent in children, and serious reactions may occur. Prospective studies are needed to confirm risk factors for IVIG-AEs and to evaluate how to best prevent them.

Levator Veli Palatini Muscle Ratio Is a Clinically Significant Anatomic Predictor for Velopharyngeal Surgical Need.

Velopharyngeal insufficiency (VPI) poses challenges for normal speech production, often necessitating surgical intervention. Determining optimal candidates for surgery remains complex and requires a nuanced understanding of underlying anatomic factors contributing to VPI. This study aimed to identify anatomic predictors that drive surgical recommendations for VPI. Prospective observational cohort study. Pediatric tertiary care hospital. Magnetic resonance imaging data were acquired from 150 children (aged 4-17) to identify anatomic predictors of VPI and surgical need. Fourteen velopharyngeal variables were measured in the oblique coronal and midsagittal imaging planes. Calculations included differences in levator veli palatini (LVP) muscle angles of origin, mean extravelar length, differences between left and right extravelar segments, the VP Needs ratio, and a newly developed LVP ratio. Multivariate logistic regression models with k-fold cross validation were utilized to identify anatomic profiles predictive of VPI and receiving a surgical recommendation. The models demonstrated high accuracy, sensitivity, and specificity. Among anatomic variables, the LVP ratio emerged as the strongest determinant of surgical need (β = 11.256, p < .001). Notably, an increase in the LVP ratio of 0.10 is associated with a 3.08-fold increase in the likelihood of receiving a surgical recommendation. LVP ratios above 1.0 were significant for both VPI classification and surgical need. The LVP ratio significantly differentiates individuals with VPI and is predictive of surgical need for VPI management. Inclusion of the LVP ratio into clinical evaluations may refine patient stratification, enabling more precise surgical decision-making tailored to individual anatomic variations.

Angiotensin-converting enzyme insertion/deletion polymorphism as a potential risk factor of congenital heart disease: insights from a tertiary pediatric cardiac care centre from North India

Background: Our study aims to elucidate the genetic influence of angiotensin-converting enzyme insertion/deletion (ACE I/D) polymorphism on congenital heart disease (CHD) in a north Indian cohort. Methods: 667 CHD cases, including 433 individuals with parental data and 104 controls were enrolled and genotyped by polymerase chain reaction. Case-control association, parental transmission test, and association of patients' and parents' clinical parameters with ACE I/D were explored. Results: Our findings highlight significant associations, notably the increased CHD risk conferred by the DD genotype in females (p=0.036; OR=1.68), its correlation with abnormal hemoglobin levels (p=0.049; OR=1.68), and its impact on primigravida (p=0.05). Conversely, the II genotype was found to significantly elevate the risk of CHD in offspring of tobacco-consuming fathers by 2.5-fold (p=0.029). Notably, cyanotic cases exhibited a heightened prevalence of ACE I/D mutations (p=0.059), with tetralogy of Fallot (TOF) showing the strongest association (p=0.024). Additionally, the DD genotype's involvement in conditions such as stenosis (p=0.026) and pulmonary artery hypertension (PAH) (p=0.05) underscores its clinical relevance. The parent of origin test showed maternal transmission of the D allele in combined (p=0.037) and acyanotic cases (p=0.039) and paternal transmission in ventricular septal defect (p=0.021). Conclusions: This is the first study from India and possibly the only study globally that reports a significant association between ACE I/D and CHD, highlighting the importance of genetic factors in CHD susceptibility.

Provision of Adolescent Confidential Care in a Pediatric Tertiary Care Hospital

PurposeAdolescents are more likely to disclose sensitive health information if confidentiality is assured. We sought to evaluate the frequency, quality, and factors associated with provision of confidential care to adolescent patients at a pediatric teaching hospital. MethodsWe undertook a cross-sectional survey of adolescents presenting to a tertiary pediatric hospital from January 2019 to January 2020. A convenience sample of adolescents eligible for confidential care under Quebec legislation (aged 14–18 years) were surveyed either following their emergency department (ED) or inpatient care. Participants completed a self-administered electronic questionnaire regarding the confidential care provided at their initial ED or inpatient medical encounter. Multivariable logistic regression was used to identify factors associated with the provision of confidential care. ResultsOverall, 406 adolescents completed the survey (335 ED; 71 inpatient); 137 (33.7%) endorsed being offered and 95 (69%) accepted confidential time. Among adolescents receiving confidential care, 43% reported that the limits of confidentiality were reviewed and 23% reported that private issues were still discussed in front of family members. Multivariable analysis revealed inpatient setting (adjusted odds ratio [aOR] 2.28, 1.04–5.01), female gender (aOR 2.02, 1.21–3.38), age (aOR 1.67, 1.03–2.69), psychiatric diagnosis (aOR 8.10, 1.47–44.6), resident involvement (aOR 1.96, I.09–3.53) were all positively associated with the provision of confidential care. DiscussionSurvey results suggest inadequate provision of confidential care in an academic pediatric hospital. The limits of confidentiality were not consistently explained, and breaches in confidentiality were not infrequent. Confidentiality-specific education initiatives are necessary to improve the frequency and quality of confidential care for adolescents in tertiary care settings.

Utility of acid citrate dextrose‐acidification for platelet volume reduction protocols in the transfusion service

AbstractBackgroundVolume‐reduced platelets can minimize circulatory overload, allergic transfusion reactions, or out‐of‐group plasma infusion. Our center adopted a volume reduction protocol that includes acidification with acid citrate dextrose solution A (ACD‐A) before centrifugation and without any rest period prior to resuspension allowing a better turnaround time for platelet issue.Study Design and MethodsThis report compares corrected count increments (CCIs) from full‐volume and ACD‐A acidified volume‐reduced human platelets in a retrospective study at a single hospital and in a mouse model.ResultsAt a pediatric tertiary care hospital, 530 patients received conventional apheresis platelets during the 20‐month study period. Among all patients, the expected 4‐h mean CCI was 9.8 (95% CI: 8.7, 10.9) for full‐volume platelets, and 8.8 (95% CI: 7.3, 10.6) for ACD‐acidified volume‐reduced platelets (p = .29). A statistically significant difference (p = .01) was identified in the expected 24‐h mean CCI: 6.3 (95% CI: 5.5–7.0) with full‐volume platelet, 4.7 (95% CI: 3.6–6.0) with ACD‐acidified volume‐reduced platelet. Limiting CCI calculations to patients with Hematology/Oncology/Hematopoietic Progenitor Cell Transplant diagnosis (n = 296, 56%) indicated a statistically significant difference in both 4‐ and 24‐h predicted CCIs, showing lower CCIs in ACD‐acidified volume‐reduced platelet, although these were still similar to the CCIs observed in all patients and considered to be clinically acceptable responses similar to other volume reduction protocols. The recovery of count‐adjusted, volume‐reduced platelets was significantly lower in mice, suggesting a procedure‐related defect.DiscussionACD‐A acidification of platelets before volume reduction decreases turnaround time for platelet issue and provides clinically allowable 4‐h and 24‐h platelet increments.

Early Endocrine and Metabolic Complications in Childhood Cancer Survivors—Experience from a Tertiary Care Pediatric Oncology Center in South India

Background Endocrine abnormalities and metabolic complications remain one of the common late effects after cancer therapy in children. Data on the incidence and pattern of complications would help to guide appropriate monitoring and treatment of childhood cancer survivors. Methods, Aims, and Objectives Purpose of study is to determine endocrine and metabolic effects in childhood cancer survivors including both hematological malignancies and solid tumors due to cancer per se and treatment-related, including different chemotherapeutic agents and radiotherapy. Results Among 97 participants, 84 children (84.5%) had at least one endocrine or metabolic complication; 41 children (42.3%) had more than two endocrine/metabolic complications. Common endocrine complications included precocious puberty (6.2%), short stature (6.2%), and hypothyroidism (5.1%). Among metabolic complications, dyslipidemia was the highest with an incidence of 68%, followed by fasting hyperinsulinism (32%), diastolic hypertension (18.6%), systolic hypertension (11.3%), obesity (8.8%), and metabolic syndrome (8.2%) and impaired fasting glucose (4.1%).Among endocrine complications, there was a significant increase in incidence of hypothyroidism among children receiving radiotherapy (odds ratio [OR]: 7.13, 95% confidence interval [CI]: 1.1–46.2), and among metabolic complications, a significant increase in incidence of metabolic syndrome in children treated with L-asparaginase compared with those not treated with L-asparaginase was observed (OR: 5.61, 95% CI: 1.07–29.5). There was no significant difference between incidence of observed endocrine and metabolic complications based on type of tumor, gender, and puberty status of study participants. Conclusion This study suggests that there is significant incidence of endocrine and metabolic complications in childhood cancer survivors, hence timely and appropriate recognition of these complications by appropriate screening recommendations and pursuing further endocrine evaluation rationally is needed.

Tertiary pediatric sleep services in Canada: A national survey

BACKGROUND Sleep disordered breathing (SDB) prevalence ranges from 10% to 14% with obstructive sleep apnea prevalence of 1-4% in the general pediatric population. Its diagnosis and management require complex testing with polysomnography and a specialized care team, often at pediatric tertiary care centers. OBJECTIVE The objectives of this study are to describe the composition of pediatric tertiary care sleep clinics across Canada and describe wait times for clinic and diagnostic services across Canada. METHODS A 6-section questionnaire was sent to 16 sleep laboratory directors from tertiary pediatric sleep centers within Canada. Questions related to sleep clinic/laboratory capacity, referral volumes, wait times and the pandemic impact. RESULTS Responses were obtained from 15 of 16 sleep laboratory directors from tertiary pediatric sleep centers within Canada. Some provinces and territories have no sleep physicians. The total number of physicians providing coverage in the sleep clinics ranged from 2 to 15 across the country. Reported volume of patients waiting for their initial assessment was greater than 300 among 5 of the 13 centers (38%) that provided a response. The potential annual number of children in each province/territory per sleep study ranged greatly from 530 to 1,530. Potential annual number of polysomnograms performed ranged from 210 to 2,700 across provinces, allowing approximately 8,110 polysomnograms per year. CONCLUSION Our recent survey demonstrates that despite the continued need for more pediatric sleep resources in Canada there remains a shortage. We estimate that even if only children with SDB were tested with a polysomnogram there are 9.39 times more children with SDB than testing capacity without accounting for incident cases.

The Maturity-Onset Diabetes of the Young (MODY) Calculator Overestimates MODY Probability in Hispanic Youth.

The applicability of the MODY risk calculator (Shields et al) to non- White European populations remains unknown. We aimed to test its real-world application in Hispanic youth. We conducted a retrospective chart review of Hispanic youth (<23 years) with diabetes (n=2033) in a large pediatric tertiary care center in the U.S. We calculated MODY probability for all subjects, splitting them into two cohorts based on the original model: Individuals who were started on insulin within 6 months of diabetes diagnosis (Cohort 1) and those who were not (Cohort 2). Cohort 1 consisted of 1566 individuals (median age [25p, 75p]: 16 [13, 19] years, 49% female), while Cohort 2 comprised 467 youth (median age [25p, 75p]: 17 [15, 20] years, 62% female). The mean MODY probability was 5.9% and 61.9% in Cohort 1 and Cohort 2, respectively. The mean probability for both cohorts combined was 18.8% suggesting an expected 382 individuals with MODY, which is much higher than previous estimations (1-5%; i.e. 20-102 individuals in this cohort). A total of 18 individuals tested positive for MODY among the limited number of individuals tested based on clinical suspicion and genetic testing availability (n=44 out of 2033 tested, [2.2% of overall cohort]). The MODY risk calculator likely overestimates the probability of MODY in Hispanic youth, largely driven by an overestimation in those not early-insulin treated (predominantly young-onset type 2 diabetes). The calculator needs updating to improve its applicability in this population. In addition, further research to help better identify MODY in Hispanic youth.

Escharotic Therapy vs. Primary Facial Closure for Omphalocele: An Early Outcome Analysis

ABSTRACT Context: Omphalocele is a congenital midline periumbilical abdominal wall defect with the herniated visceral organs covered by a membrane. The morbidity and mortality of neonates with omphalocele in our geographical area are under-evaluated. Aims: The aim of the study was to compare the early outcomes of omphalocele using two different management modalities, that is, either escharotic therapy or primary facial closure from a high-volume institute in India. Settings and Design: This prospective observational study was undertaken over a one-year duration extending from January to December 2021 at our pediatric tertiary care teaching institute. Subjects and Methods: The study included all patients with omphalocele admitted to the neonatal intensive care unit. The decision for management of the neonates with either escharotic therapy or primary facial closure was performed as per the discretion of the unit head. Results: There were 16 neonates with omphalocele; 10 (62.5%) males and six (37.5%) females. The mean birth weight was 2575 ± 839 g (range = 1700–5000 g). Associated major malformations/syndromes were observed in five (31.25%) patients. Group A (escharotic therapy) had nine patients with major omphalocele and two patients with minor omphalocele. Group B (primary facial closure of the defect) constituted four minor omphaloceles and one omphalocele major with a ruptured sac. Out of 11 patients in group A, nine survived (favorable outcomes); the cause of death in two patients was associated with cyanotic heart disease and cloacal exstrophy. Out of the five patients in group B, two survived (favorable outcomes); the cause of death in two patients was postoperative sepsis due to ruptured sac and associated OEIS syndrome. One patient had multi-organ dysfunction syndrome as a consequence of abdominal compartment syndrome. Conclusions: The survival percentage of neonates with escharotic therapy (81.82%) was better than primary facial closure (40%). The creation of ventral hernia is a better modality of management in neonates with omphalocele, especially in a resource-limited center.

Multisystem Inflammatory Syndrome in Children (MIS-C) in a Lithuanian Paediatric Tertiary Care Center.

Background and Objectives: Due to its link with the SARS-CoV-2, Multisystem Inflammatory Syndrome in Children (MIS-C) gained global attention as a serious condition that requires hospital care. Our study aimed to present the clinical and laboratory characteristics of MIS-C patients by age group and intensive care unit (ICU) admission status and assess early echocardiographic changes. Materials and Methods: A single-center partly retrospective, partly prospective observational cohort study was performed from December 2020 to June 2024. The study included 42 patients aged between 1 month and 18 years who were diagnosed with MIS-C and gave informed consent. Results: The median age was 6.5 years (IQR 2.0-9.3). The predominant symptoms were cardiovascular (88.1%), mucocutaneous (85.7%) and gastrointestinal (76.2%). Five children (11.9%) developed shock. About two-thirds of patients (66.7%) were admitted to the ICU. Adolescents (≥12 years) were less likely to exhibit mucocutaneous or cardiovascular symptoms and thus less frequently having Kawasaki-like disease symptoms compared with other age groups (<5 years or 5-11 years). Lymphopenia was more common among patients aged 5 years and older. Adolescents had higher procalcitonin (PCT) and a lower estimated glomerular filtration rate. Troponin I and B-type natriuretic peptide (BNP) levels were higher in children aged 5-11 years, while ferritin levels were lower among the youngest (<5 years). Patients treated at the ICU were more likely to have cardiovascular and respiratory symptoms, as well as a history of symptomatic COVID-19, higher C-reactive protein (CRP), PCT, BNP and lower albumin levels. Echocardiographic abnormalities were found in 71.4% of cases. During hospitalization, left ventricular ejection fraction values increased significantly (p < 0.001) over 12 (IQR 9.0-14.0) days. Conclusions: Symptoms and laboratory markers of MIS-C vary according to age. Higher CRP, PCT, BNP and hypoalbuminemia are predictors of MIS-C severity. Cardiovascular involvement is common and might be severe, but rapid resolution is encouraging.

Cluster Analysis of Migraine-associated Symptoms (CAMS) in youth: A retrospective cross-sectional multicenter study.

To conduct a retrospective cross-sectional multicenter study to validate the relationships between migraine-associated symptoms. Symptoms associated with headache-photophobia and phonophobia, nausea, and/or vomiting-are required criteria for migraine diagnosis based on the International Classification of Headache Disorders-Third Edition (ICHD-3). However, individuals with migraine report high rates of other symptoms (e.g., lightheadedness, difficulty thinking). We recently completed a single-center study assessing the relationships between an expanded set of migraine-associated symptoms. A pre-registered cross-sectional multicenter retrospective analysis was conducted on standardized questionnaire data of youth ages 6-17 years from two headache registries at pediatric tertiary care centers. Cluster Analysis of Migraine-associated Symptoms (CAMS) was implemented to assess associations between 11 migraine-associated symptoms. We explored differences between the two centers, and how CAMS was associated with demographics, including sex and age, and headache burden. There were 10,721 participants who were 66.5% female and had a median (interquartile range) age of 13 (10-15) years. The first three CAMS dimensions accounted for 46.5% of the variance and were consistent across sites. The first dimension indicated those reporting any migraine-associated symptoms were likely to report multiple. The second dimension separated symptoms into those included in ICHD-3 migraine diagnostic criteria and non-ICHD symptoms (e.g., lightheadedness, difficulty thinking). The third dimension separated sensory hypersensitivity and vestibular symptoms. An abundance of migraine-associated symptoms correlated with greater headache severity (Spearman's ρ = 0.18, 95% confidence interval [CI] 0.17-0.20; small effect size) and disability (ρ = 0.26, 95% CI 0.25-0.28; small effect size). We also observed differences in associated symptoms across age and sex. Associations between an expanded set of migraine-associated symptoms are informative for headache burden and reveal intriguing changes across child development and sex. We were able to replicate findings across two centers, indicating that these symptom clusters are inherent to migraine.

87 Far from home: Qualitative evaluation of the impact of geographic distance from a tertiary paediatric hospital in Canada on family experiences

Abstract Background Canada’s expansive geography has implications for children and their families seeking tertiary paediatric care. There is minimal literature describing their experiences, particularly challenges associated with receiving inpatient care. This qualitative study builds on previous work that captured out-of-pocket costs and stress levels facing families while admitted to our hospital. Objectives Gather an in-depth understanding of family experiences through exploring gaps in current approaches and supports received 2) Generate potential patient-centred solutions to challenges identified Design/Methods Ethics approval was obtained. Family partners were involved in all aspects of study design. Qualitative descriptive methodology was adopted to allow for in-depth exploration of family experiences. Semi-structured interviews explored the above objectives. Participants were families that travelled more than 50 km to receive inpatient care under General Paediatrics at a tertiary hospital in Canada within 1 year of when the interview was conducted. In addition, families were purposively recruited through collaboration with community paediatricians until theoretical saturation was reached. Interviews were transcribed verbatim, de-identified, and analyzed for common themes using descriptive analysis in NVivo software. Results Between June and October 2023, 16 caregivers participated in our study. The key themes identified were in the following categories: navigating the unknown, bridging the gaps for far away families through equitable resources, and the role of self-advocacy. Families spoke to the overwhelm they faced when being admitted to our centre. For many, it was their first time in our city and the costs associated with being in this city were significant. They identified key gaps in resources and supports, such as knowledge of medical teams, difficulties with eligibility requirements and reimbursement, and inadequate availability of resources after-hours and on weekends. Self-advocacy was important to all participants and innovative solutions were proposed, such as knowledge exchange facilitated by caregivers with lived experience and caregiver-facilitated trainings for providers. Conclusion This qualitative study highlights the unique challenges facing families traveling significant distances to receive essential healthcare at a tertiary paediatric hospital in Canada. While significant gaps in resources exist, participants suggested innovative, patient-centred, equitable strategies to bridge these gaps. We plan to partner with patient partners to translate this data into evidence-based interventions to support these families at our institution.

Impact of an Adult Congenital Heart Disease Order Set in a Pediatric Cardiac Intensive Care Unit.

Background: Patients with congenital heart disease (CHD) are increasingly surviving to adulthood. Given their age- and condition-specific needs, the optimal postoperative setting for these patients is not yet determined. This study aims to evaluate the utility of an adult-specific order set in improving clinical outcomes for these patients in a pediatric cardiovascular intensive care unit (ICU). Methods: Adults with CHD (ACHD) admitted to the cardiovascular ICU following cardiac surgery at a pediatric tertiary care center were identified for a retrospective cohort study. Health care delivery metrics and clinical outcomes of participants who received the adult-specific order set were compared with control patients admitted prior to the intervention. Categorical outcomes were compared using the χ2 test of independence or Fisher exact test, and continuous outcomes were assessed using the t test. Results: A total of 130 ACHD patients received the intervention, with no significant differences observed in clinical outcomes when compared with 89 controls. While there was additionally no reduction in hospital-related mortality (2.3% vs 7.8%, RR 0.3; P = .1), clinician ordering behaviors were better aligned with best-practices following the intervention. Among patients with moderate or greater anatomic complexity, a post hoc analysis demonstrated reduced in-hospital mortality from those who received the adult order set. Conclusions: The implementation of an adult-specific order set in a pediatric care setting did not improve clinical outcomes for all ACHD patients. Patients with moderate and greater anatomic complexity did see a mortality benefit, suggestive that targeted electronic tools may most benefit those who have the highest risk.

52 The bag is not always bad: Implementing a two-step method for urine testing on the inpatient paediatric units

Abstract Background Urinary tract infections (UTIs) are a common source of infection in children. Best practice for diagnosis includes interpreting a urinalysis (UA) and urine culture. Urine cultures obtained through bladder catheterization are invasive and time consuming. A two-step approach with noninvasive UA screen, followed by urine culture if positive has previously demonstrated a reduction in unnecessary catheterizations and urine cultures in children 6-24 months with suspected UTIs. Pre-intervention, there was inconsistent use of screening point-of-care urinalysis prior to bladder catheterization for culture. Objectives To decrease the number of bladder catheterizations in children 6-24 months with a negative screen on Point of Care Test (POCT) urinalysis by 25% over 1 year on paediatrics wards at a paediatric tertiary care centre. Outcome measures: 1. Proportion of bladder catheterizations with negative or no UA screen prior 2. Proportion of UA completed as POCT rather than lab sample Process measures: 1. Number of urinary catheterizations performed for UTI screen 2. Number of times pathway is followed Balancing measure: 1. Missed UTIs Design/Methods Baseline data was collected from the paediatric inpatient units at a tertiary paediatric hospital from April 2020 – April 2021. A two-step pathway for collecting urine samples was adopted, including POCT UA screen on a bag sample, followed by bladder catheterization for culture if positive. The pathway was implemented using the Model for Improvement and multiple PDSA cycles. Intervention focused on education, interdisciplinary collaboration, and process standardization. Results Baseline data demonstrated a high rate of urinary catheter cultures despite a negative UA or no UA prior (69%). After pathway implementation, this rate decreased to 23%, with a reduction in initial UA collected by catheter from 14% to 5% (figure 1). The number of POCT UA performed has increased from a median of 64% pre-intervention to 80% post-intervention, resulting in fewer samples processed in the lab (figure 2). Conclusion Variability in practice for specimen choice for collection and investigation contributed to unnecessary catheterizations. Process standardization successfully improved patient-centered care and efficiency. Next steps include broadening pathway inclusion criteria to the 3–6-month age group.

19 How are paediatric tertiary care hospitals structured to respond to the needs of children with medical complexity during acute deteriorations? A landscape study in Canada

Abstract Background Children with medical complexity (CMC) are at risk of unplanned healthcare visits especially due to acute clinical deteriorations. Complex care (CC) programs help facilitate the needs of CMC. Objectives To identify the organizational and administrative resources available for the care of CMC in Canadian tertiary care paediatric hospitals and to assess how physicians believe these resources are adapted to the specific urgent needs of CMC. Design/Methods In this observational study, key informants representing complex care (CC) and paediatric emergency medicine (PEM) services from 15 paediatric tertiary care hospitals in Canada completed cross-sectional structured questionnaires. Participants were identified through national research networks (Pediatric Emergency Research Canada (PERC), Pediatric Inpatient Research Network (PIRN) and by snowball sampling. Utilizing the Lime Survey web application, two questionnaires (one for PEM, one for CC) were develop based on a literature review and following Burns methodology. Verbal questionnaires were administered via a secured teleconference application or completed digitally. Descriptive data were generated using Excel and SPSS v.29. Results From 09/2022 to 09/2023, 93% (28/30) key informants completed questionnaires (15 PEM, 13 CC, Table 1). Across the 15 sites, 12 had a CC program or clinic. Information about established CC programs was available for 10 sites (Table 2), from participating CC informants: 4/10 offered outpatient services; 6/10 offered inpatient and outpatient services; 8/10 offered last minute appointments for CMC. CC programs had variable staffing: mostly physicians (median 3 FTE, range: 0.2-6) and nurse practitioners (0.75 FTE, range: 0-9) or registered nurses (0.9 FTE, 0-8). CC informants reported offering an ED consultation service at 8/10 sites, while 6/12 PEM participants reported access to such a service. CC informants reported that their program rarely offered consultations during weekends (2/10) or nights (1/10). Across all sites, PEM informants reported good access to documents to help with continuity of care including emergency care plans (13/15), medical history (14/15), goals of care (13/15). Using an 11-point scale, CC informants rated their hospital’s median ability to meet the outpatient needs of CMC as 6.5 (range: 0-10), and their ED’s median ability to meet the needs of CMC as 7 (range 5-10). PEM informants reported their median ability to meet the needs of CMC as 8 (range 6-9). Informants made suggestions to improve the ED care of CMC (Table 3). Conclusion There exists wide variation in the structures caring for CMC and their availability in case of acute needs. National collaboration between CC and PEM teams may facilitate the design of programs to improve the acute outpatient care of CMC.

12 Access to paediatric maltreatment services through a northern community hospital

Abstract Background Few studies have evaluated how paediatric maltreatment services based in community hospitals can provide access to care for populations who live far away from tertiary centres. The Violence Intervention Prevention Program (VIPP) and the Paediatric Abuse and Referral Evaluation (PARE) clinic based in a northern community hospital in Canada offer assessment for sexual and physical maltreatment. Objectives The aim of the study was to describe demographic and clinical characteristics of patients accessing VIPP and PARE services and to characterize the length of time required to access care. Design/Methods We conducted a retrospective chart review of patients, under 16 years of age, who attended PARE clinic for initial consultation between 2017-2019. Analyses were descriptive. This work was approved by the research ethics board at our hospital. There are no funding disclosures. Results Of 164 patients, 62.2% were female; 37.8% male. The mean age was 6.6 years, ranging from 1 month to 15.9 years. 54.3% of referrals were for suspected physical maltreatment, 44.4% for suspected sexual maltreatment and 1.2% for both. 87.5% of patients listed home addresses within the hospital’s city limits. The maximum distance travelled from home to access care was 171 km. 87.2% of patients presented through the emergency department; a minority presented through direct referral to outpatient services (11.5%) or through inpatient (1.2%). When called from the emergency department, on-call VIPP nurses responded within a mean of 32 minutes for initial assessment. These patients received a maltreatment assessment by a paediatrician through the PARE clinic a mean of 14.3 days later. If patients did not present through the emergency department, the mean wait time for a maltreatment assessment by a paediatrician was 16 days. 13.4% (22/164) required referral to other medical or multidisciplinary services. General paediatrics (11/22) was the most frequent referral, followed by community speech programs (5/22). A minority (3.0%) of cases required consultation with external maltreatment teams, where two cases were peer-reviewed with a tertiary care team, one with a paediatric maltreatment physician at another community hospital and two cases were reviewed with a paediatric tertiary care radiologist. Conclusion Our results suggest that community-based paediatric maltreatment services provide care for our regional northern population. There is timely on-call access to allied-health providers through the emergency department. All patients were able to be assessed locally and none were required to travel to a tertiary care hospital. Further study is needed to assess how our data compares to other community maltreatment programs.

Racial, Ethnic, and Socioeconomic Disparities in Pediatric Aquaporin-4-Positive Neuromyelitis Optica Spectrum Disorder

BackgroundOnly 5% of aquaporin-4-positive neuromyelitis optica spectrum disorder (AQP4+ NMOSD) cases emerge during childhood. Poorer outcomes have been suggested in black/African American (AA) adults with NMOSD; however, conflicting and limited data exist for pediatric-onset NMOSD. This study evaluates racial, ethnic, and socioeconomic disparities in pediatric AQP4+ NMOSD outcomes. MethodsThirty-eight pediatric patients with AQP4+ NMOSD cared for at three pediatric tertiary care centers between 2009 and 2021 were identified. Patient addresses connected to socioeconomic measures available from the US Census. Demographic characteristics, pertinent clinical outcomes, and health care utilization in the two years following diagnosis were captured. ResultsCompared with non-Hispanic White children, Black/AA children had a significantly higher Expanded Disability Status Scale (EDSS) (2.46 vs 0.33, P = 0.003), 2.37 more hospital admissions (P = 0.002), and 28.40 additional inpatient days (P = 0.002) in the two years following their NMOSD diagnosis. Additionally, children with public insurance had higher relapse rates than those with private insurance (P = 0.046). At two years and at the most recent follow-up, a significantly higher EDSS was correlated with children living in census tracts with a lower median income, higher deprivation index, and higher proportion of population on assisted income, in poverty, and with vacant housing (all P < 0.05). ConclusionsWe identified racial, ethnic, and socioeconomic disparities in clinical outcomes and health care utilization in pediatric AQP4+ NMOSD. Further prospective and household-level data are needed to dissect the interplay of genetics, structural racism, and social determinants of health so that interventions to optimize care and outcomes for this population may be developed.

The Initial Experience of Eslicarbazepine in Children at Three Canadian Tertiary Pediatric Care Centers.

Eslicarbazepine (ESL) is a once-daily, third-generation antiseizure medication for focal-onset seizures. The primary mechanism of action is enhancing the slow inactivation of voltage-gated sodium channels. The study objective was to review real-world experience regarding retention rate, efficacy, and tolerability of eslicarbazepine, soon after it became available for children in Canada. A retrospective review was performed on all patients prescribed eslicarbazepine from September 2017 to June 2020, with at least 3 years of follow-up data, at 3 Canadian tertiary care pediatric centers. Fifty patients were identified, and the mean age of eslicarbazepine initiation was 12.4 years (range 3-19 years). Most patients had drug-resistant epilepsy, trying a mean of 5.04 (range 0-14) antiseizure medications before the initiation of eslicarbazepine. Twenty-four patients (48.0%) experienced adverse effects, including dizziness (n = 10), drowsiness (n = 6), dizziness and drowsiness (n = 1), nausea and abdominal pain (n = 4), transient unsteadiness and diplopia (n = 1), and negative mood changes (n = 2). None had serious adverse effects, including rash. The retention rate of eslicarbazepine at last follow-up was 70%. Fifteen (30%) had ≥50% seizure reduction, with 2 of these patients becoming seizure free. Ten (20%) had 25% to 50% reduction, 2 (4%) had worsening of seizures, and 17 (34%) had no change in seizure frequency. The study results support the long-term effectiveness and tolerability of eslicarbazepine in a cohort of children with predominantly drug-resistant epilepsy in a real-life setting from 3 Canadian centers with initial use after approval. Adverse effects were nonserious, infrequently leading to eslicarbazepine discontinuation.

Frequency of Surgical Site Infection in Patients Operated on by The General Surgery Department in a Tertiary Care Pediatric Hospital, From September 1, 2014 To August 31, 2015

This observational, descriptive, and ambispective study aims to determine the frequency of surgical site infections (SSIs) among patients treated in the general surgery department of the National Institute of Pediatrics between September 1, 2014, and August 31, 2015. Currently, surgical site infection (SSI) represents a significant cause of morbidity and mortality on a global scale. The objective of this study is to ascertain the percentage of patients who present with SSIs in accordance with the CDC specifications, thereby establishing a basis and reference for subsequent studies.
