Interfacility Transfer Outcomes Among Children With Complex Chronic Conditions: Associations Between Patient-Level and Hospital-Level Factors and Transfer Outcomes.

OBJECTIVES: Determine patient- and referring hospital-level predictors of transfer outcomes among children with 1 or more complex chronic conditions (CCCs) transferred to a large academic medical center. METHODS: We conducted a retrospective chart review of 2063 pediatric inpatient admissions from 2017 to 2019 with at least 1 CCC defined by International Classification of Diseases, Tenth Revision codes. Charts were excluded if patients were admitted via any route other than transfer from a referring hospital's emergency department or inpatient ward. Patient-level factors were race/ethnicity, payer, and area median income. Hospital-level factors included the clinician type initiating transfer and whether the referring-hospital had an inpatient pediatric ward. Transfer outcomes were rapid response within 24 hours of admission, Pediatric Early Warning Score at admission, and hours to arrival. Regression analyses adjusted for age were used to determine association between patient- and hospital-level predictors with transfer outcomes. RESULTS: There were no significant associations between patient-level predictors and transfer outcomes. Hospital-level adjusted analyses indicated that transfers from hospitals without inpatient pediatrics wards had lower odds of ICU admission during hospitalization (odds ratio, 0.46; 95% confidence interval, 0.22-0.97) and shorter transfer times (ß-coefficient, -2.54; 95% CI, -3.60 to -1.49) versus transfers from hospitals with inpatient pediatrics wards. There were no significant associations between clinician type and transfer outcomes. CONCLUSIONS: For pediatric patients with CCCs, patient-level predictors were not associated with clinical outcomes. Transfers from hospitals without inpatient pediatric wards were less likely to require ICU admission and had shorter interfacility transfer times compared with those from hospitals with inpatient pediatrics wards.

More Than a Headache: Lived Experience of Migraine in Youth.

BACKGROUND: Migraine is the leading cause of disability among adolescents and young adults. We aimed to characterize the impact of migraine on the experience of children, adolescents, and caregivers. METHODS: This descriptive qualitative study recruited youth aged four to 18 years with migraine and their caregivers from the multicenter, prospective Pediatric Migraine Registry between 2020 and 2021. Participants completed semistructured interviews targeting the lived experience of migraine. A conventional content analysis approach was used to analyze data. RESULTS: Thirty enrolled dyads (n = 30 children and adolescents, n = 29 caregivers) completed 59 interviews (n = 29 child and adolescent interviews, n = 30 caregiver interviews). Children and adolescents had a median age of 15 years and experienced a median of 13.5 headache days per month. Caregivers had a median age of 44 years and predominantly identified as mothers (n = 28). We identified three themes: (1) Impact on emotional well-being: participants described how their migraine experience included feelings of isolation, depression, and irritability alongside the need for social support; (2) Impact on daily life: participants described how symptoms and unpredictability impacted their ability to perform activities of daily living; and (3) Impact on school: participants described how migraine impacted their school experience, including threatened attendance and worsened performance. CONCLUSIONS: In this cohort of youth and their caregivers, we identified salient themes to characterize the experience of migraine. Our findings underscore the urgent need for effective migraine treatments and interventions targeting co-occurring mental health conditions, peer relationships, and school support.

Transition from pediatric to adult care in type 1 diabetes mellitus: a longitudinal analysis of age at transfer and gap in care.

INTRODUCTION: Adolescents and young adults (AYAs) with type 1 diabetes (T1D) are at risk of suboptimal glycemic control and high acute care utilization. Little is known about the optimal age to transfer people with T1D to adult care, or time gap between completing pediatric care and beginning adult endocrinology care. RESEARCH DESIGN AND METHODS: This retrospective, longitudinal study examined the transition of AYAs with T1D who received endocrinology care within Duke University Health System. We used linear multivariable or Poisson regression modeling to assess the association of (1) sociodemographic and clinical factors associated with gap in care and age at transfer among AYAs and (2) the impact of gap in care and age at transfer on subsequent glycemic control and acute care utilization. RESULTS: There were 214 subjects included in the analysis (54.2% female, 72.8% white). The median time to transition and age at transition were 8.0 months and 21.5 years old, respectively. The median gap in care was extended by a factor of 3.39 (95% CI=1.25 to 9.22, p=0.02) for those who did not see a mental health provider pre-transfer. Individuals who did not see a diabetes educator in pediatrics had an increase in mean age at transition of 2.62 years (95% CI=0.93 to 4.32, p<0.01). The post-transfer emergency department visit rate was increased for every month increase in gap in care by a relative factor of 1.07 (95% CI=1.03 to 1.11, p<0.01). For every year increase in age at transition, post-transfer hospitalization rate was associated with a reduction of a relative factor of 0.62 (95% CI=0.45 to 0.85, p<0.01) and emergency department visit rate by 0.58 (95% CI=0.45 to 0.76, p<0.01). CONCLUSIONS: Most AYAs with T1D have a prolonged gap in care. When designing interventions to improve health outcomes for AYAs transitioning from pediatric to adult-based care, we should aim to minimize gaps in care.

Beyond pain control: Outcome and treatment preferences in pediatric migraine.

OBJECTIVE: The objective of this study was to describe treatment preferences and perceived quality of existing outcome measures among children and adolescents with migraine and their caregivers. BACKGROUND: Across disciplines, there is increasing recognition of the value of direct input from stakeholders. Little empirical work has been done to determine what outcomes matter most to pediatric patients with migraine and their caregivers. METHODS: In this qualitative study, we recruited participants from the multicenter, prospective Pediatric Migraine Registry. We used stratified purposive sampling to recruit children and adolescents of varied ages and headache frequency. Patients with migraine and their caregivers completed semistructured interviews targeting treatment preferences and perceived quality of existing outcome measures. Emergent themes and subthemes were identified using conventional content analysis. RESULTS: Thirty dyads of children/adolescents and their caregivers were enrolled and completed 59 interviews (n = 29 children/adolescent interviews and n = 30 caregiver interviews). Three themes emerged. (1) Symptom relief: Looking beyond headache resolution: Participants described the value of outcomes in addition to pain relief, including a reduction in migraine intensity and improvement in non-pain symptoms. (2) Trade-offs between side effects and relief: Participants described cost-benefit analyses that can occur with headache treatment and acknowledged the impact of drug side effects on daily life and medication adherence. (3) Child-centered treatment: Participants described medication attributes salient to the pediatric context, including age-appropriate routes of administration and adequate safety data. CONCLUSIONS: Children, adolescents, and caregivers impacted by migraine value outcomes in addition to traditionally studied migraine endpoints. Participants valued decreased pain severity, even in the absence of pain resolution. Participants also prioritized the absence of side effects and key medication attributes, including fast onset and age-appropriate routes of administration. These results highlight an opportunity to design patient-centered clinical trials, develop drugs, and support product labeling that align with the outcomes valued most by children and adolescents with migraine and their caregivers.

Pediatric GAD-65 Autoimmune Encephalitis: Assessing Clinical Characteristics and Response to Therapy With a Novel Assessment Scale.

BACKGROUND: Glutamic acid decarboxylase (GAD) encephalitis is a neuroinflammatory disease characterized by a broad range of symptoms including cognitive deficits, behavioral changes, and seizures. Children with this disorder have heterogeneous presentations, and little is known about symptom progression over time and response to immunotherapy. METHODS: This study reports 10 pediatric GAD encephalitis cases and symptoms found at presentation and follow-up. In addition, symptom severity was reported utilizing a novel scale evaluating functional outcomes across the domains affected by autoimmune encephalitis including cognition, language, seizures, psychiatric symptoms, sleep, and movement. Retrospective chart review was conducted for 10 patients aged <18 years, diagnosed with GAD encephalitis, and followed for one year or more. Chart review included clinical, imaging, and laboratory findings at time of diagnosis and at six- and 12-month follow-ups. RESULTS: At presentation, cognitive deficits were found in all patients, seizures in six of 10, and language decline in seven of 10. Psychiatric symptoms were prominent for all but one patient with three of nine patients presenting with psychosis. Fatigue, sleep disruption, and movement disorders were less prominent symptoms, occurring in approximately half of the cohort. Cognition and fatigue improved significantly over time when compared with symptom severity, whereas seizures, psychiatric symptoms, and sleep did not. Language and sleep showed improvement only in early stages. Analysis of seizure frequency and type noted variability mirroring trends noted in adult studies of GAD encephalitis. CONCLUSIONS: This study demonstrated the variability of symptom profiles of pediatric GAD encephalitis and benefits of symptom severity scales. Symptom profiles and progression vary in this population.

Development and Evaluation of a Virtual Population of Children with Obesity for Physiologically Based Pharmacokinetic Modeling.

BACKGROUND AND OBJECTIVE: While one in five children in the USA are now obese, and more than three-quarters receive at least one drug during childhood, there is limited dosing guidance for this vulnerable patient population. Physiologically based pharmacokinetic modeling can bridge the gap in the understanding of how pharmacokinetics, including drug distribution and clearance, changes with obesity by incorporating known obesity-related physiological changes in children. The objective of this study was to develop a virtual population of children with obesity to enable physiologically based pharmacokinetic modeling, then use the novel virtual population in conjunction with previously developed models of clindamycin and trimethoprim/sulfamethoxazole to better understand dosing of these drugs in children with obesity. METHODS: To enable physiologically based pharmacokinetic modeling, a virtual population of children with obesity was developed using national survey, electronic health record, and clinical trial data, as well as data extracted from the literature. The virtual population accounts for key obesity-related changes in physiology relevant to pharmacokinetics, including increased body size, body composition, organ size and blood flow, plasma protein concentrations, and glomerular filtration rate. The virtual population was then used to predict the pharmacokinetics of clindamycin and trimethoprim/sulfamethoxazole in children with obesity using previously developed physiologically based pharmacokinetic models. RESULTS: Model simulations predicted observed concentrations well, with an overall average fold error of 1.09, 1.24, and 1.53 for clindamycin, trimethoprim, and sulfamethoxazole, respectively. Relative to children without obesity, children with obesity experienced decreased clindamycin and trimethoprim/sulfamethoxazole weight-normalized clearance and volume of distribution, and higher absolute doses under recommended pediatric weight-based dosing regimens. CONCLUSIONS: Model simulations support current recommended weight-based dosing in children with obesity for clindamycin and trimethoprim/sulfamethoxazole, as they met target exposure despite these changes in clearance and volume of distribution.

Annexin A1 is a Potential Novel Biomarker of Congestion in Acute Heart Failure.

OBJECTIVES: This study sought to identify the role of annexin A1 (AnxA1) as a congestion marker in acute heart failure (AHF) and to identify its putative role in predicting clinical outcomes. BACKGROUND: AnxA1 is a protein that inhibits inflammation following ischemia-reperfusion injury in cardiorenal tissues. Because AHF is a state of tissue hypoperfusion, we hypothesized that plasma AnxA1 levels are altered in AHF. METHODS: In the Renal Optimization Strategies Evaluation (ROSE) trial, patients hospitalized for AHF with kidney injury were randomized to receive dopamine, nesiritide, or placebo for 72 hours in addition to diuresis. In a subanalysis, plasma AnxA1 levels were measured at baseline and at 72 hours in 275 patients. Participants were divided into 3 tertiles based on their baseline AnxA1 levels. RESULTS: The prevalence of peripheral edema 2+ increased with increasing AnxA1 levels (P < .007). Cystatin C, blood urea nitrogen, and kidney injury molecule-1 plasma levels were higher among participants in tertile 3 vs tertiles 1 or 2 (P< .05). Patients with a congestion score of 4 had a mean baseline AnxA1 level 8.63 units higher than those with a congestion score of 0 (P = .03). Patients in tertiles 2 and 3 were twice as likely to experience creatinine elevation as patients in tertile 1 (P = .03). Patients in tertiles 2 and 3 were at a higher risk of 60-day all-cause mortality or heart failure hospitalization and 180-day all-cause mortality (P < .05). CONCLUSIONS: Among patients hospitalized for AHF with impaired kidney function, elevated AnxA1 levels are associated with worse congestion, higher risk for further creatinine elevation, and higher rates of 60-day morbidity or all-cause mortality and 180-day all-cause mortality.

Quality of life in heart failure with preserved ejection fraction: importance of obesity, functional capacity, and physical inactivity.

AIMS: Patient-reported quality of life (QOL) is a highly prognostic and clinically relevant endpoint in patients with heart failure (HF) with preserved ejection fraction (HFpEF). The relationships between QOL and different markers of HF severity remain unclear, particularly as they relate to functional capacity and directly measured activity levels. We hypothesized that QOL would demonstrate a stronger relationship with measures of exercise capacity and adiposity compared to other disease measures. METHODS AND RESULTS: This is a secondary analysis of the National Heart, Lung, and Blood Institute-sponsored RELAX, NEAT-HFpEF and INDIE-HFpEF trials to determine the relationships between QOL (assessed by the Kansas City Cardiomyopathy Questionnaire and Minnesota Living with Heart Failure Questionnaire) and different domains reflecting HF severity, including maximal aerobic capacity (peak oxygen consumption), submaximal exercise capacity (6-min walk distance), volume of daily activity (accelerometry), physician-estimated functional class, resting echocardiography, and plasma natriuretic peptide levels. A total of 408 unique patients with chronic HFpEF were split into tertiles of QOL scores defined as QOLworst, QOLintermediate , QOLbest . The QOLworst HFpEF group was youngest, with a higher body mass index, greater prevalence of class II obesity and diabetes, and the lowest N-terminal pro-brain natriuretic peptide (NT-proBNP) levels. After adjustment for age, sex and body mass index, poorer QOL was associated with worse physical capacity and activity levels, assessed by peak oxygen consumption, 6-min walk distance and actigraphy, but was not associated with NT-proBNP or indices from resting echocardiography. QOL was similarly reduced in patients with and without prior HF hospitalization. CONCLUSIONS: Quality of life in HFpEF is poorest in patients who are young, obese and have diabetes, and is more robustly tied to measures reflecting functional capacity and daily activity levels rather than elevations in NT-proBNP or prior HF hospitalization. These findings have major implications for the understanding of QOL in HFpEF and for the design of future clinical trials targeting symptom improvement in HFpEF.

History of Atrial Fibrillation and Trajectory of Decongestion in Acute Heart Failure.

OBJECTIVES: This study sought to characterize the course of decongestion among patients hospitalized for acute heart failure (AHF) by history of atrial fibrillation (AF) and/or atrial flutter (AFL). BACKGROUND: AF/AFL and chronic heart failure (HF) commonly coexist. Little is known regarding the impact of AF/AFL on relief of congestion among patients who develop AHF. METHODS: We pooled patients from 3 randomized trials of AHF conducted within the Heart Failure Network, the DOSE (Diuretic Optimization Strategies) trial, the ROSE (Renal Optimization Strategies) trial, and the CARRESS-HF (Cardiorenal Rescue Study in Acute Decompensated Heart Failure) trial. The association between history of AF/AFL and in-hospital changes in various metrics of congestion was assessed using covariate-adjusted linear and ordinal logistic regression models. RESULTS: Of 750 unique patients, 418 (56%) had a history of AF/AFL. Left ventricular ejection fraction was higher (35% vs. 27%, respectively; p < 0.001), and N-terminal pro-brain natriuretic peptide (NT-proBNP) levels were nonsignificantly lower at baseline (4,210 pg/ml vs. 5,037 pg/ml, respectively; p = 0.27) in patients with AF/AFL. After adjustment of covariates, history of AF/AFL was associated with less substantial loss of weight (-5.7% vs. -6.5%, respectively; p = 0.02) and decrease in NT-proBNP levels (-18.7% vs. -31.3%, respectively; p = 0.003) by 72 or 96 h. History of AF/AFL was also associated with a blunted increase in global sense of well being at 72 or 96 h (p = 0.04). There was no association between history of AF/AFL and change in orthodema congestion score (p = 0.67) or 60-day composite clinical endpoint (all-cause mortality or any rehospitalization; hazard ratio: 1.21; 95% confidence interval: 0.92 to 1.59; p = 0.17). CONCLUSIONS: More than half of the patients admitted with AHF had a history of AF/AFL. History of AF/AFL was independently associated with a blunted course of in-hospital decongestion. Further research is required to understand the utility of specific therapies targeting AF/AFL during hospitalization for AHF.
