Inequities in Inpatient Pediatric Patient Safety Events by Category.

Few studies have analyzed potential inequities in both pediatric patient safety events (PSEs) and adverse events (AEs) - PSEs leading to harm - nor in PSEs by event type. We sought to examine potential inequities in rates of pediatric PSEs overall, by severity, and by category based on race and ethnicity, insurance payor, and language as measured using voluntary incident reports (IRs). We conducted a retrospective cohort study of pediatric hospitalizations between January 19, 2012 through December 31, 2019 at a US urban, tertiary care children's hospital. Analyzing 85 458 hospitalizations, we compared PSEs overall, by severity, and by event category by race and ethnicity, insurance payor, and language using incident rate ratios (IRRs). In models controlling for covariates, we found that hospitalizations of Latinx (IRR 1.17, 95% confidence interval [CI] 1.07-1.29), non-Latinx Black/African American (IRR 1.17, 95% CI 1.01-1.34), publicly insured (IRR 1.10, 95% CI 1.02-1.20), and nonprivately/nonpublicly insured (IRR 1.12, 95% CI 1.02-1.23) children had higher rates of PSEs compared with reference groups, but the association between language and PSEs was not significant. There were similar patterns among AEs, although only the association between hospitalizations of Latinx patients and AEs was significant. Medication, fluid, or blood and lines or tubes PSEs drove many inequities. We found inequities in PSEs as recorded by IRs, suggesting differences in care related to race, ethnicity, and payor. Limitations include analysis of a single center, that event categories are unique to the institution analyzed, and the voluntary nature of IRs.

Respiratory viruses associated with severe acute respiratory infection in children aged

With the increased availability of licensed vaccines for respiratory viruses such as severe acute respiratory syndrome coronavirus 2, respiratory syncytial virus (RSV), and influenza virus, a better understanding of the viral aetiology of severe acute respiratory infections (SARI) among children could help in optimising the use of these vaccines. We conducted a study among children aged <5 years hospitalised with SARI at a tertiary care children's hospital in north India and tested for common respiratory pathogens. We randomly enrolled eligible SARI cases aged <5 years from August 2013 to July 2015. SARI cases were defined as either <7-day history of fever with cough or in children aged eight days to three months, a physician diagnosis of acute lower respiratory infection requiring hospitalisation. We also enrolled an age-group matched control without any acute illness in a 2:1 ratio from the outpatient clinic within 24 hours of case enrolment. Nasopharyngeal and/or oropharyngeal swabs were collected and tested using TaqMan Array Cards, a real-time reverse transcription polymerase chain reaction-based multi-pathogen testing platform for selected respiratory viruses among the enrolled cases and controls. We compared the prevalence of each pathogen among cases and controls using the χ2 (χ2) or Fisher exact test (P < 0.05). We used logistic regression to estimate adjusted odds ratios (aORs) which were then used to calculate aetiologic fractions (EFs). We enrolled 840 cases and 419 outpatient controls. Almost half of the individuals in the whole sample were aged <6 months (n = 521, 41.4%). Females made up 33.7% of cases and 37.2% of controls. Viral detections were more common among cases (69%, 95% confidence interval (CI) = 66, 73) compared to controls (33%; 95% CI = 29, 38) (P < 0.01). RSV (n = 257, 31%; 95% CI = 28, 34%) was the most common virus detected among cases. Influenza A was detected among 24 (3%; 95% CI = 2, 4%), and influenza B among 5 (1%; 95% CI = 0, 1%) cases. The association between the virus and SARI was strongest for RSV (aOR = 23; 95% CI = 12, 47; EF = 96%). Antivirals were administered to 1% of SARI cases while 78% received antibiotics. Using a multi-pathogen molecular detection method, we detected respiratory viruses among more than two-thirds of children aged <5 years admitted with SARI in the Delhi tertiary care children's hospital. The guidelines for preventing and managing SARI cases among children could be optimised further with the improved availability of antivirals and vaccines.

Obstructive hydrocephalus due to developmental venous anomalies: a pediatric imaging case series.

Developmental venous anomalies are a rare cause of obstructive hydrocephalus in the pediatric population. In this study, we present the most extensive case series of DVA-induced obstructive hydrocephalus in the pediatric population. We thoroughly describe the imaging findings related to this uncommon entity and comprehensively discuss its clinical presentation and management strategies. The goal is to alert pediatric neuroradiologists to consider this rare condition in the differential diagnosis of hydrocephalus, particularly during prenatal screening or in pediatric cases. The electronic patient record systems of 2 tertiary care children's hospitals were reviewed to identify pediatric patients with confirmed DVAs leading to obstructive hydrocephalus. Age at diagnosis, gender, MRI findings (including location of the obstruction), clinical presentation, and symptoms were recorded. Data on treatment and follow-up imaging were also collected. The search yielded 5 cases of pediatric patients with DVA-induced obstructive hydrocephalus. The mean age at diagnosis of the DVA was 2.9 years (range: 0-7 years), and in two cases, ventriculomegaly was diagnosed in utero during prenatal cranial ultrasound screenings. In all patients, the DVA caused stenosis of the aqueduct of Sylvius, and one case presented with multiple DVAs. Although aqueductal stenosis caused by a DVA is rare, it is crucial to consider it in the differential diagnosis of hydrocephalus during prenatal screening or in the pediatric population. Brain MRI, especially post-contrast T1WI, and SWI sequences are particularly valuable for visualizing the typical "caput medusae" appearance of DVAs and detecting associated complications such as hemorrhages.

Outcomes of open reduction for hip dislocations in children with connective tissue disorders.

While children with hypermobility and/or ligamentous laxity due to coexisting connective tissue disorders might be expected to have worse outcomes after open reduction for hip dislocations, there is minimal prior research on this topic. All open reduction surgeries for hip dislocations performed at a single urban, tertiary-care children's hospital from 2009 to 2023 were reviewed retrospectively. Those with connective tissue disorders secondary to a diagnosed syndrome or genetic disorder were included. Patients with <1 year of follow-up or hip instability in the setting of Trisomy 21 were excluded. Clinical and radiographic data was collected. Instances of re-dislocation, proximal femoral growth disturbance, residual acetabular dysplasia, and arthrofibrosis were recorded. Twenty-three hips (15 patients) were included. Mean age at the time of surgery was 19.6 months (Range: 8.2-36.0 months), and mean follow-up was 4.3 years. The most common connective tissue disorder condition included was Ehlers-Danlos syndrome (13%). A majority of open reductions were performed via an anterior approach (96%). Seven hips (30%) underwent a concomitant pelvic osteotomy without femoral osteotomy and seven hips (30%) underwent both pelvic and femoral osteotomies. Twenty-two hips (96%) were International Hip Dysplasia Institute grade 1 at the final follow-up. Re-dislocation occurred in four hips (17%); eight hips (35%) demonstrated residual acetabular dysplasia, five hips (22%) demonstrated proximal femoral growth disturbance, and nine hips (39%) developed stiffness postoperatively. Patients with connective tissue disorders and ligamentous laxity have comparable rates of residual acetabular dysplasia, proximal femoral growth disturbance, and (surprisingly) stiffness as typical developmental dysplasia of the hip following open hip reduction surgery. Although the re-dislocation rate in the connective tissue disorders group was approximately 2-3 times higher, the difference did not reach statistical significance. Given that the study was limited by a low sample size, however, it is possible that the findings of no difference in residual acetabular dysplasia and proximal femoral growth disturbance were potentially due to a lack of power.

Incidence of an Identifiable Organism in Children Who Underwent a Surgical Procedure for Granulomatous Cervical Lymphadenopathy.

Objectives: The incidence of cervical lymphadenopathy due to nontuberculous mycobacteria is rising in the pediatric population. Our goal with this study was to review the number of pediatric patients with granulomatous cervical adenitis and determine the incidence of identification of a specific organism as both healthcare providers and parents are interested in identifying the causative pathogen. Methods: A retrospective chart review was conducted of patients at a high-volume tertiary care children's hospital between 2017 and 2023. Children were included if they underwent a surgical procedure for lymphadenopathy. Pathology, microbiology, and other laboratory reports were reviewed to document the presence of granulomatous cervical adenitis and the incidence of identification of a specific organism. Additional data collected included patient demographics and type of procedure. Results: Of the 1538 charts reviewed, 163 patients underwent an inclusionary procedure. Mean patient age was 10.7 years (range 2.4 months-20 years), 70 (43%) were female, 25 (15%) had granulomatous cervical adenitis, and a specific organism was identified in 9 of these. Conclusion: Despite the availability of a number of ancillary tests, our data demonstrate that the identification of a specific pathogen in cases of granulomatous cervical lymphadenitis is rare. As a result, physicians should be prepared to rely primarily on the history and physical exam findings to determine a working diagnosis as well as a medical and/or surgical treatment plan.

Outcomes of heliox use in children with respiratory compromise: A 10-year single institution experience.

Heliox, a mixture of helium and oxygen, has been shown to improve laminar airflow and decrease airway resistance in children. This study aims to describe the outcomes of heliox use in children with respiratory compromise and to identify variables associated with a need for airway surgical intervention. A retrospective cohort study of patients who received heliox between 2012 and 2022 at a tertiary care children's hospital. A hundred and thirty-eight heliox treatments were recorded in 119 children. Twelve patients were excluded. Most (n = 100, 84%) patients had significant comorbidities. On average, patients spent a cumulative mean of 94 ± 187 h on heliox therapy per hospital admission. Patients with croup or asthma without known airway pathology presented at an older age than patients with other indications for heliox therapy (4.0 ± 4.7 vs. 2.2 ± 3.6 years, p = 0.04) and were significantly less likely to have background diseases (n = 14, 52% vs. n = 74, 93%, p < 0.0001). Overall, 51 (47.7%) patients were recommended tracheostomy placement, airway reconstruction, or palliative care. Cumulative use of heliox for more than 47 h was associated with an increased risk of needing tracheostomy or airway reconstruction (odds ratio 6.2, 95% confidence intervals 2.56-14.13, p < 0.0001). In multivariable regression analysis, neuromuscular disease, intracranial neuropathology, and cumulative time of heliox were associated with a need for definitive airway intervention. Heliox may be used as a temporizing agent in children with upper airway obstruction. The effectiveness of heliox use for more than 47 h in children, especially in the presence of neuromuscular disease and intracranial neuropathology should be reconsidered.Level of evidence: 4.

Cost-Benefit Analysis of a Pediatric ICU Sedation Weaning Protocol.

A risk stratified sedation weaning protocol improved patient outcomes in a pediatric intensive care unit (PICU). We sought to determine the protocol effect on medication costs. This was a retrospective observational cohort study in an academic tertiary care children's hospital PICU (2018-2020) comparing the cost when weaning benzodiazepine, alpha agonist, and/or opioid infusions in intubated children <18 years of age. There were 84 total sedation weaning instances (pre-protocol n = 41 and post-protocol n = 41); 2 patients had 2 encounters, 1 in each phase. The total cost (in 2022 United States Dollars) of sedation weaning was $400,328.87 ($15,994.44/kg) pre-protocol compared with $170,458.85 ($11,227.52/kg) post-protocol. The median cost of sedation wean per patient for pre-protocol patients was $3197.42 (IQR: $322.66-$12,643.29) and post-protocol patients was $1851.44 (IQR: $425.05-$5355.85; p = 0.275). A linear regression model estimated the expected cost of sedation wean for post-protocol patients to be $5173.20 lower than for pre-protocol patients of the same weight and overall drug risk (p = 0.036). The proportion of withdrawal symptoms in the pre-protocol patients (16%) was not significantly different from the proportion in the post-protocol patients (14%; p = 0.435). Implementation of a PICU sedation weaning protocol in a single-center conferred cost benefit without negatively impacting patient outcomes. A larger multicenter study would provide insight to the applicability to PICUs in varied settings with differing patient populations.

Predicting Parental Post-Traumatic Stress Symptoms Following their Child's Stay in a Pediatric Intensive Care Unit, Prior to Discharge.

Objective: Develop an inpatient predictive model of parental post-traumatic stress (PTS) following their child's care in the Pediatric Intensive Care Unit (PICU). Design: Prospective observational cohort. Setting: Two tertiary care children's hospitals with mixed medical/surgical/cardiac PICUs. Subjects: Parents of patients admitted to the PICU. Interventions: None. Measurements and Main Results: Preadmission and admission data from 169 parents of 129 children who completed follow up screening for parental post-traumatic stress symptoms at 3-9 months post PICU discharge were utilized to develop a predictive model estimating the risk of parental PTS 3-9 months after hospital discharge. The parent cohort was predominantly female (63%), partnered (75%), and working (70%). Child median age was 3 years (IQR 0.36-9.04), and more than half had chronic illnesses (56%) or previous ICU admissions (64%). Thirty-five percent (60/169) of parents met criteria for PTS (>9 on the Post-traumatic Stress Disorder Symptom Scale-Interview). The machine learning model (XGBoost) predicted subjects with parental PTS with 76.7% accuracy, had a sensitivity of 0.83 (95% CI 0.586, 0.964), a specificity of 0.72 (95% CI 0.506, 0.879), a precision of 0.682 (95% CI 0.451, 0.861) and number needed to evaluate of 1.47 (95% CI 1.16, 1.98). The area under the receiver operating curve was 0.78 (95% CI 0.64, 0.92). The most important predictive pre-admission and admission variables were determined using the Local Interpretable Model-Agnostic Explanation, which identified seven variables used 100% of the time. Composite variables of parental history of mental illness and traumatic experiences were most important. Conclusion: A machine learning model using parent risk factors predicted subsequent PTS at 3-9 months following their child's PICU discharge with an accuracy of 76.7% and number needed to evaluate of 1.47. This performance is sufficient to identify parents who are at risk during hospitalization, making inpatient and acute post admission mitigation initiatives possible.

Youth and Family Perspectives on Diagnosis Communication About Pediatric Functional Seizures: A Qualitative Study

BackgroundThis study aims to understand diagnosis communication experiences and preferences of youths with functional seizures and their parents. MethodsSemistructured interviews with youths and their parents from a tertiary care children's hospital were conducted separately. We confirmed the diagnosis of functional seizures with the youth's treating providers. All interviews were audio recorded and professionally transcribed. Two coders performed thematic analysis and determined themes. ResultsThirteen youths (aged 12 to 18) and 13 parents completed interviews separately. Themes included the following: (1) both parents and youths reported substantial fear about their symptoms, diagnosis, prognosis, and treatment options; (2) good communication skills highlighted included providing reassurance, listening, and allowing time for questions, with different preferences between youths and parents in the mode of communication; (3) poor communication for both youths and parents included use of medical jargon, brevity of communication especially with the youth, minimization of youth's symptoms, lack of apparent compassion, and lack of written materials to supplement discussions; (4) perspectives on the role of mental health in functional seizures were heterogeneous, yet concrete treatment plans were desired including access to behavioral therapy; and (5) youths and parents wanted practical guidance including plans for school and how to respond to functional seizures in all settings. ConclusionsYouths and parents provided concrete recommendations for optimal diagnosis communication. Study findings will inform the future development of an educational intervention to improve communication and create a supportive environment for youths with functional seizures.

Aspirations Dashed: Conventional Synovial Fluid Analysis Is Superior to Synovial Fluid and Blood Neutrophil-to-Lymphocyte Ratios in Diagnosing Pediatric Septic Arthritis of the Hip and Knee.

Recent research suggests that synovial fluid neutrophil-to-lymphocyte ratio (SF-NLR) is a superior diagnostic for pyogenic septic arthritis (SA) in adults compared with synovial fluid white blood cell count (SF-WBC) ≥50,000 cells/μL or ≥90% polymorphonuclear leukocytes (SF-%PMN). Other research also indicates that the neutrophil-to-lymphocyte ratio in the blood (B-NLR) may be of diagnostic significance. However, it is not known whether these findings extend to the pediatric population. Medical records at a large urban tertiary-care children's hospital were queried for emergency department visits between 2012 and 2023, where synovial fluid (SF) analysis was performed to evaluate for SA of the hip or knee. Patients 18 years old and above were excluded. The "conventional composite test" (CCT) for SA was considered positive if SF analysis showed any of the following: (1) SF-WBC ≥50,000 cells/μL, (2) ≥90% PMNs, or (3) organisms reported on gram stain. Patients with aspirate and/or operating room (OR) cultures (or supplemental testing, ie, nucleic acid identification) revealing an offending organism were considered to have culture-positive septic arthritis (CPSA). The remaining patients were considered culture-negative (CN). Serum and SF test data were analyzed to assess their diagnostic utility in identifying CPSA. Receiver operating characteristic (ROC) curves were examined to compare the predictive value of SF-NLR and B-NLR versus conventional indicators of SA. A total of 394 patients met the inclusion criteria. In all, 58.6% (n=231) were male, 67.5% (n=266) involved the knee, and 20.1% (n=79) had CPSA. Those with CPSA had higher ESR and CRP compared with CN patients (P<0.01). Bivariate testing did not show a difference in SF-NLR or B-NLR between those with CPSA and CN patients (P=0.93 and 0.37, respectively). The CCT showed 91% sensitivity and 35% specificity using conventional thresholds. ROC analysis showed that SF-WBC was superior to SF-NLR and B-NLR in the diagnosis of CPSA (AUC=0.71 vs. 0.50 and 0.53, respectively; both P<0.01). Among CCT (+) patients who ended up culture negative, Lyme testing was positive in 48.8% (100/205). In contrast to adults, SF-NLR and B-NLR were not found to be strong diagnostic indicators of SA of the hip or knee in pediatric patients. This may be because competing diagnoses in children come with systemic inflammatory responses similar to that seen in pyogenic SA, while noninfectious conditions that might represent the major alternate diagnoses in adults do not increase systemic inflammatory markers as significantly. Given the high incidence of Lyme disease seen among patients in this study, this topic should be further studied at pediatric centers outside Lyme-endemic areas to better understand the generalizability of these findings. Despite excitement regarding SF-NLR and B-NLR as diagnostics for adult SA, these criteria appear less useful in the diagnosis of pyogenic SA in pediatric patients in Lyme-endemic areas.

Postoperative Respiratory Complications After Adenotonsillectomy in Children With High-Risk Obstructive Sleep Apnea.

Identify patient characteristics and polysomnogram (PSG) parameters associated with postoperative respiratory complications after adenotonsillectomy (AT) among children with high-risk obstructive sleep apnea (OSA). Case series with chart review. Tertiary care children's hospital. Pediatric patients (<18 years) with high-risk OSA (any 1 of: apnea-hypopnea index [AHI] >30, O2 nadir <80% and peak CO2 >60 mm Hg) on overnight PSG from 2019 to 2021 were included. Primary outcomes were major respiratory intervention during the postoperative admission, prolonged hospitalization, and intensive care unit (ICU) stay. A total of 307 patients met inclusion criteria. Median age was 6.5 years and 63% were male. Twenty-five (8.1%) required major respiratory intervention and 29 (9.7%) required ICU admission after AT. Major interventions and ICU admissions were significantly associated with neuromuscular disease (P < .01), higher obstructive apnea-hypopnea index (oAHI), higher CO2 peak, and lower O2 nadir. Prolonged admission had similar findings except oAHI was not significantly associated. Younger children were significant more likely to require ICU admission or prolonged admission. Increased oAHI and worsening O2 and CO2 parameters on preoperative PSG were associated with postoperative respiratory complications in children with high-risk OSA. Children with neuromuscular disease and age 0 to 2 had higher risk of ICU stay and prolonged hospitalization. Clinicians should recognize the importance of parameters beyond oAHI when anticipating postoperative monitoring.

Palliative Care for Dialysis-Dependent Pediatric Patients: A Survey of Providers, Nurses, and Caregivers.

Dialysis-dependent pediatric patients and their families face significant biopsychosocial burdens and low health-related quality of life. Palliative care consultations can alleviate some degree of suffering for patients and families but remain underutilized within pediatric nephrology. Little is known about how providers, nurses, and caregivers perceive palliative care integration into the multidisciplinary care of dialysis-dependent pediatric patients. This study surveyed pediatric nephrology providers (physicians and advanced practice providers), inpatient pediatric nephrology bedside nurses, and caregivers of dialysis-dependent pediatric patients at a freestanding tertiary care children's hospital in Dallas, Texas. Participants completed a survey regarding knowledge about, experiences with, and perceptions of palliative care in pediatric nephrology. 10 providers, 20 nurses, and 18 caregivers completed the survey. Although 80% of providers and all nurses agreed that palliative care would benefit dialysis-dependent pediatric patients, most believed that palliative care is not as important in pediatric nephrology as it should be. 70% of providers and 45% of nurses believed that they understand the scope of palliative care. 90% of providers and all nurses desired more palliative care education. Of the 22% of caregivers whose child had already received palliative care services, all found the consultation to be helpful. Many providers and nurses worried that a palliative care consultation would signal to families that the nephrology team would be giving up on their child and that their child is approaching the end of life. However, no caregivers thought that a consultation would mean that the nephrology team would be giving up on their child and only 6% worried that it would indicate that their child is approaching the end of life. These data support further palliative care education for pediatric nephrology providers and nurses and more robust and systematic involvement of subspecialty palliative care for dialysis-dependent pediatric patients.

Socioeconomic factors in inflicted traumatic brain injury: Examining the area deprivation index.

Inflicted traumatic brain injury (iTBI), or abusive head injury, is a common cause of mortality and disability among infants and toddlers. Social determinants of health (SDoH) have a critical and multifaceted impact on iTBI, influencing both prevalence and outcomes. The area deprivation index (ADI) is a comprehensive metric of SDoH developed to assist in understanding how community-level socioeconomic factors influence patient outcomes. The current study sought to describe the sociodemographic characteristics, including ADI, of a cohort of 373 infants and young children who sustained an iTBI. This study was a retrospective analysis utilizing a cohort of pediatric patients treated for iTBI at a large, tertiary care children's hospital serving seven states in the Rocky Mountain region. Mortality prevalence was higher among older children, and older children were more likely to have a longer stay in the pediatric intensive care unit. Children who were identified as Hispanic/Latino lived in areas with greater socioeconomic disadvantage than children identified as non-Hispanic/Latino. Specifically, participants who were identified as White Hispanic/Latino lived in areas with greater disadvantage than children who were identified as White non-Hispanic/Latino. There were no other significant differences by race. Contrary to hypotheses, ADI was not significantly related to mortality, injury severity, or follow-up visits. While SDoH are known to influence outcomes in iTBI, it may be necessary to incorporate individual or family-level SDoH variables within this clinical sample and examine the interaction between individual and community-level factors.

Improving genetic testing utilization in a tertiary care neonatal intensive care unit through quality improvement.

There is an increasing recognition of the importance of diagnosing genetic conditions with an ever-growing list of genetic testing options. However, most providers do not have formal genetics training, which makes choosing the most appropriate test to order challenging. Our project sought to improve cytogenetic testing utilization in a tertiary care neonatal intensive care unit (NICU) through utilizing quality improvement techniques, specifically the Model for Improvement framework with rapid Plan-Do-Study-Act cycles. Our project utilized various interventions including the implementation of a NICU genetic testing algorithm. Interventions demonstrated improvement in all areas, specifically a 92% reduction in unnecessary cytogenetic testing with improvement in the diagnostic rate. Our work also resulted in a 59% decrease in charges with an estimated projected savings of $21,000 per year. Quality improvement can minimize redundancies and inefficiencies in genetic testing in a Level IV NICU in a large tertiary care children's hospital and result in substantial cost-savings.

Electrocardiogram Abnormalities in Children With Lyme Arthritis.

Classically, Lyme disease follows a staged illness pattern with carditis occurring in early disseminated disease and arthritis in late-stage disease. A more comprehensive understanding of Lyme suggests that clinical stages may intersect. Little is known regarding the overlap of electrocardiogram (ECG) abnormalities in children with Lyme arthritis. This study aimed to estimate the prevalence of ECG changes in pediatric patients presenting with Lyme arthritis. In this retrospective, cross-sectional study was conducted at a tertiary care children's hospital in a Lyme endemic area; patients were identified based on Lyme testing performed from January 2012 to August 2022. Children diagnosed with Lyme arthritis by 2-tiered serology with ECGs obtained within 2 days of antibiotic initiation were included. A study cardiologist reviewed all ECGs for evidence of carditis defined as atrioventricular block, ST-T wave changes, QTc interval prolongation, accelerated junctional rhythm or right bundle branch block. Two hundred thirty-three patients were diagnosed with Lyme arthritis; 90 (38.6%) had ECGs completed. Five patients (5.6%) had ECG abnormalities: 3 were diagnosed with first-degree atrioventricular block, 1 with QTc prolongation, and 1 with ST-T wave changes. No clinical or laboratory features in patients with Lyme arthritis were associated with an increased likelihood of having an abnormal ECG. All patients with ECG abnormalities were treated with oral antibiotics, and none had clinically significant cardiac disease. ECG abnormalities in children with Lyme arthritis rarely occur and, when present, are not reflective of clinically significant cardiac disease. These results do not support routine screening ECGs on asymptomatic pediatric patients with Lyme arthritis.

Effectiveness of art therapy interventions for treating pain and anxiety in adolescents in the emergency department.

To evaluate the effectiveness of art therapy in reducing pain and anxiety in adolescents with painful conditions treated in the ED. We conducted a prospective pilot study of patients 12-18years old presenting with a painful condition to a tertiary-care children's hospital ED. Primary outcome was pain intensity measured using the Verbal Numerical Rating Scale (scored 0-10); a decrease of ≥ 20% was clinically significant. Anxiety was measured using the short-form six-item State-Trait Anxiety Inventory (scored 20-80: 20-40 = zero-low anxiety; 41-60 = moderate anxiety; 61-80 = high anxiety); a change from higher to lower category was clinically significant. Outcomes were measured at baseline, immediately after, and 1h after art therapy completion. A standardized interview was conducted immediately after art therapy completion. We enrolled a convenience sample of 50 patients. Mean duration of art therapy was 34.7min. Mean baseline pain was 6.2 and decreased by 23.2% (95% CI 14.9-31.5) and 28.6% (95% CI 9.2-48), immediately after and 1h after art therapy completion, respectively. Mean baseline anxiety was 48 (moderate) and decreased to 38 (low) and 43 (moderate) at the same time points, respectively. Forty-eight patients (96%) reported feelings of relaxation, decreased pain intensity, and/or empowerment (e.g., "Very relaxing"; "I didn't feel as much pain"; "Really showed my emotions"; "A way to explain to doctors what I'm feeling and what parts hurt"). Art therapy may be associated with clinically significant decreases and qualitative improvements in pain and anxiety in adolescents with painful conditions being treated in the ED. This novel treatment may improve the holistic care of adolescents with painful conditions in the ED.

Etiological Spectrum of Lymphadenopathy Among Children on Lymph Node Biopsy.

Background Pediatric peripheral lymphadenopathy is commonly a benign condition and most cases resolve spontaneously; however, it can be a manifestation of a serious underlying disease. This study aimed to determine the etiological spectrum of persistent pediatric lymphadenopathy on excisional biopsy in a tertiary care children's hospital in a low-middle-income country and to make recommendations regarding evaluation, diagnostic testing, and surgical interventions best suited to the population. Methodology A prospective cross-sectionalstudy was conducted on 243 pediatric patients between the ages of one to 12 years undergoing excisional biopsy for persistent lymphadenopathy (more than four weeks duration) from April 1, 2021, to March 31, 2024. Patient demographic data along with signs, symptoms, and results of investigations including histopathological diagnosis were documented on a structured proforma. Results Patients' age range was two to 12 years (mean = 7.29 ± 2.30 years). The male-to-female ratio was 1:53. The Mean duration of lymphadenopathy was 35.89 ± 6.95 days (range = 25 to 57 days). The average size of lymph nodes ranged from 1 cm to a complex nodal mass of 7 cm. Histopathology showed reactive hyperplasia (40.32%, n = 98), tuberculosis (TB) (33.7%, n = 82), lymphoma (10.3%, n = 25), atypical mycobacterial adenitis (6.99%, n = 17), chronic granulomatous inflammation-histiocytosis (6.2%, n = 15), and Langerhans cell histiocytosis (2.5%, n = 6). The most common site was cervical. Sputum GeneXpert for TB had a true-positive rate of 78.84% while PPD was positive in only 13 TB patients. Atypical mycobacterial adenitis was successfully treated with excision and antibiotics. Supraclavicular nodes were strongly associated with lymphoma (p = 0.008). Conclusions Persistent pediatric lymphadenopathy is most commonly caused by TB followed by lymphoma. Positive sputum GeneXpert for TB with a suggestive clinical picture in endemic regions may be sufficient to start empiric therapy without the need for excisional biopsy in mycobacterial TB adenitis with negative PPD results and normal chest X-ray. In all other cases, excisional biopsy remains the gold standard for diagnosis. However, further studies should be conducted to formulate less invasive management algorithms.

Complications of Hardware Removal in Pediatric Orthopaedic Surgery.

Hardware removal (HR) is one of the most common surgical procedures in pediatric orthopaedics. Surgeons advocate for HR for a variety of reasons, including to limit peri-implant fracture risk, restore native anatomy for adult reconstruction surgery, permit bone growth and development, and mitigate implant-related pain/irritation. To our knowledge, no recent study has investigated the characteristics and complications of HR in pediatric orthopaedics. The goal of this study is to report the prevalence and complications of hardware removals across all of pediatric orthopaedic surgery. A retrospective case series was conducted of all hardware removals from 2012 to 2023 performed at a single urban tertiary-care children's hospital. Cases were identified using CPT codes/billing records. Spinal hardware and cases for which hardware was either implanted or explanted at an outside hospital were excluded. Patient demographic and clinical data were recorded. For patients with multiple hardware removals, each case was recorded independently. A total of 2585 HR cases for 2176 children met study criteria (57.7% male; mean age 12.3±4.4y). The median postoperative follow-up time was 1.7 months (interquartile range: 0.6 to 6.9). The most common sites of hardware removal were the femur/knee (32.7%), tibia/fibula/ankle (19.3%), and pelvis/hip (18.5%). The most common complications included sustained, new-onset postoperative pain (2.6%), incomplete hardware removal (1.6%), and perioperative fracture (1.4%). The overall complication rate of hardware removal was 9.5%. Eighty-eight percent of patients who underwent hardware removal for pain experienced pain relief postoperatively. HR >18 months after insertion had a 1.2x higher odds of overall complication (P=0.002) and 3x higher odds of incomplete removal/breakage (P<0.001) than hardware removed 9 to 18 months after insertion. The overall complication rate of hardware removal across a large series in the pediatric population was 9.5%. Despite hardware removal being one of the most common and often routine procedures in pediatric orthopaedics, the complication rate is not benign. Surgeons should inform patients and families about the likelihood of success and the risks of incomplete removal during the informed consent process. IV.

Healthcare utilization in patients with head and neck lymphatic malformations with the introduction of sirolimus

ObjectivesHistorically, head and neck lymphatic malformations (HNLM) have been managed through surgical and interventional procedures. Sirolimus was introduced in 2016 and has aided in symptomatic control of HNLM. The study objective was to assess healthcare utilization with the introduction of sirolimus for HNLM. MethodsAn observational cohort study of LM patients treated between 2008 and 2022 at a tertiary care children's hospital was performed. 588 charts were reviewed; patients with isolated, non-syndromic HNLM and at least 2 years of follow-up were included (n = 45). Data included sirolimus use, complications, presence of tracheostomy and/or gastrostomy-tube, and number and costs of HNLM-related sclerotherapies, procedures, hospitalizations, and emergency room visits. For patients who received sirolimus, encounters two years prior to and after sirolimus initiation were recorded. For the non-sirolimus group, encounters two years after the initial clinic visit for HNLM were recorded. Statistical analysis was used to compare the groups. ResultsMedian age at first clinic visit was 1.8 years (range 2 days–41 years). Tracheostomy was present in 43 % of sirolimus patients compared with 3 % of the non-sirolimus group (OR: 24.0, 95%CI: 1.55–1490, p = 0.02). Patients on sirolimus experienced significantly fewer sclerotherapy visits (z = 2.08, p = 0.03) compared to the non-sirolimus group. Minimal sirolimus-related side effects were reported. Total HNLM-related costs were significantly less in the sirolimus group during treatment (median $448.13, range $0–$7041.28) compared with before treatment (median $17,069.24, range $1999.16–$211,848.50, z = 2.20, p = 0.03). Median costs associated with sclerotherapy were less for the sirolimus groups during treatment compared with the non-sirolimus group (z = 1.97, p = 0.04). In the sirolimus group, costs associated with HNLM-related hospitalizations were significantly less during sirolimus treatment compared with before (z = 2.20, p = 0.03). ConclusionSirolimus has improved the clinical course for HNLM patients by decreasing number of procedures and healthcare costs, with limited side effects. Larger cohorts matching type of HNLM and age are needed to assess healthcare utilization benefits of sirolimus.
