Implications of Large Language Models for Quality and Efficiency of Neurologic Care: Emerging Issues in Neurology

Large language models (LLMs) are advanced artificial intelligence (AI) systems that excel in recognizing and generating human-like language, possibly serving as valuable tools for neurology-related information tasks. Although LLMs have shown remarkable potential in various areas, their performance in the dynamic environment of daily clinical practice remains uncertain. This article outlines multiple limitations and challenges of using LLMs in clinical settings that need to be addressed, including limited clinical reasoning, variable reliability and accuracy, reproducibility bias, self-serving bias, sponsorship bias, and potential for exacerbating health care disparities. These challenges are further compounded by practical business considerations and infrastructure requirements, including associated costs. To overcome these hurdles and harness the potential of LLMs effectively, this article includes considerations for health care organizations, researchers, and neurologists contemplating the use of LLMs in clinical practice. It is essential for health care organizations to cultivate a culture that welcomes AI solutions and aligns them seamlessly with health care operations. Clear objectives and business plans should guide the selection of AI solutions, ensuring they meet organizational needs and budget considerations. Engaging both clinical and nonclinical stakeholders can help secure necessary resources, foster trust, and ensure the long-term sustainability of AI implementations. Testing, validation, training, and ongoing monitoring are pivotal for successful integration. For neurologists, safeguarding patient data privacy is paramount. Seeking guidance from institutional information technology resources for informed, compliant decisions, and remaining vigilant against biases in LLM outputs are essential practices in responsible and unbiased utilization of AI tools. In research, obtaining institutional review board approval is crucial when dealing with patient data, even if deidentified, to ensure ethical use. Compliance with established guidelines like SPIRIT-AI, MI-CLAIM, and CONSORT-AI is necessary to maintain consistency and mitigate biases in AI research. In summary, the integration of LLMs into clinical neurology offers immense promise while presenting formidable challenges. Awareness of these considerations is vital for harnessing the potential of AI in neurologic care effectively and enhancing patient care quality and safety. The article serves as a guide for health care organizations, researchers, and neurologists navigating this transformative landscape.

Screening for Quality of Life in a Neurology Tic Clinic Using Quality Improvement Methodology

BACKGROUND

Tic disorders in children often co-occur with other disorders that can significantly impact functioning. Screening for quality of life (QoL) can help identify optimal treatment paths. This quality improvement (QI) study describes implementation of a QoL measure in a busy neurology clinic to help guide psychological intervention for patients with tics.

METHODS

Using QI methodology outlined by the Institute for Healthcare Improvement, this study implemented the PedsQL Generic Core (4.0) in an outpatient medical clinic specializing in the diagnosis and treatment of tic disorders. Assembling a research team to design process maps and key driver diagrams helped identify gaps in the screening process. Conducting several plan-do-study-act cycles refined identification of patients appropriate to receive the measure. Over the three-year study, electronic health record notification tools and data collection were increasingly utilized to capture patients' information during their visit.

RESULTS

Over 350 unique patients were screened during the assessment period. Electronic means replaced paper measures as time progressed. The percentage of patients completing the measure increased from 0% to 51.9% after the initial implementation of process improvement, advancing to 91.6% after the introduction of electronic measures. This average completion rate was sustained for 15 months.

CONCLUSIONS

Using QI methodology helped identify the pragmatics of implementing a QoL assessment to enhance screening practices in a busy medical clinic. Assessment review at the time of appointment helped inform treatment and referral decisions.

Implementing American Academy of Neurology Quality Measures in Antigua Using Quality Improvement Methodology

Background and Objectives

The American Academy of Neurology has developed quality measures related to various neurologic disorders. A gap exists in the implementation of these measures in the different health care systems. To date, there has been no electronic health care record nor implementation of quality measures in Antigua. Therefore, we aimed to increase the percent of patients who have epilepsy quality measures documented using standardized common data elements in the outpatient neurology clinic at Sir Lester Bird Medical Center from 0% to 80% per week by June 1, 2022 and sustain for 6 months.

Methods

We used the Institute for Health care Improvement Model for Improvement methodology. A data use agreement was implemented. Data were displayed using statistical process control charts and the American Society for Quality criteria to determine statistical significance and centerline shifts.

Results

Current and future state process maps were developed to determine areas of opportunity for interventions. Interventions were developed following a "Plan-Do-Study-Act cycle." One intervention was the creation of a RedCap survey and database to be used by health care providers during clinical patient encounters. Because of multiple interventions, we achieved a 100% utilization of the survey for clinical care.

Discussion

Quality improvement (QI) methodology can be used for implementation of quality measures in various settings to improve patient care outcomes without use of significant resources. Implementation of quality measures can increase efficiency in clinical delivery. Similar QI methodology could be implemented in other resource-limited countries of the Caribbean and globally.

Severe communication delays are independent of seizure burden and persist despite contemporary treatments in SCN1A+ Dravet syndrome: Insights from the ENVISION natural history study

OBJECTIVE

Dravet syndrome (DS) is a developmental and epileptic encephalopathy characterized by high seizure burden, treatment-resistant epilepsy, and developmental stagnation. Family members rate communication deficits among the most impactful disease manifestations. We evaluated seizure burden and language/communication development in children with DS.

METHODS

ENVISION was a prospective, observational study evaluating children with DS associated with SCN1A pathogenic variants (SCN1A+ DS) enrolled at age ≤5 years. Seizure burden and antiseizure medications were assessed every 3 months and communication and language every 6 months with the Bayley Scales of Infant and Toddler Development 3rd edition and the parent-reported Vineland Adaptive Behavior Scales 3rd edition. We report data from the first year of observation, including analyses stratified by age at Baseline: 0:6-2:0 years:months (Y:M; youngest), 2:1-3:6 Y:M (middle), and 3:7-5:0 Y:M (oldest).

RESULTS

Between December 2020 and March 2023, 58 children with DS enrolled at 16 sites internationally. Median follow-up was 17.5 months (range = .0-24.0), with 54 of 58 (93.1%) followed for at least 6 months and 51 of 58 (87.9%) for 12 months. Monthly countable seizure frequency (MCSF) increased with age (median [minimum-maximum] = 1.0 in the youngest [1.0-70.0] and middle [1.0-242.0] age groups and 4.5 [.0-2647.0] in the oldest age group), and remained high, despite use of currently approved antiseizure medications. Language/communication delays were observed early, and developmental stagnation occurred after age 2 years with both instruments. In predictive modeling, chronologic age was the only significant covariate of seizure frequency (effect size = .52, p = .024). MCSF, number of antiseizure medications, age at first seizure, and convulsive status epilepticus were not predictors of language/communication raw scores.

SIGNIFICANCE

In infants and young children with SCN1A+ DS, language/communication delay and stagnation were independent of seizure burden. Our findings emphasize that the optimal therapeutic window to prevent language/communication delay is before 3 years of age.

Multidisciplinary Care for Pediatric Patients With Psychogenic Nonepileptic Seizures May Be Associated With Decreased Health Care Utilization

Background and Objectives

Psychogenic nonepileptic seizures (PNES) are paroxysmal events that resemble epileptic seizures but have psychological underpinnings. Patients with PNES have high health care utilization. We hypothesize that appropriate care would lead to decreases in utilization. The aim of this study was to measure the impact of a multidisciplinary PNES clinic in reducing health care utilization (HCU) in youth with PNES referred to the clinic.

Methods

We reviewed the frequency of visits to the emergency department (ED), urgent care (UC), planned and unplanned hospitalizations, neurodiagnostic studies, and total charges associated with these encounters 12 months before and 12 months after initial referral to the clinic. Manual chart review of all patients referred from November 2017 to March 2020 was performed.

Results

Two hundred and twelve unique patients were included in this retrospective study. Patient sex was identified as 71% female, 28% male, and 1% other, with an average age of 14 years at diagnosis. These patients visited the ED a total of 410 times before being seen in the PNES clinic, which decreased to 187 visits after (75% reduction). All measures of HCU decreased in the 12 months after the visit, and statistically significant differences were observed in all measures of HCU except for head MRIs, leading to an estimated potential cost savings of $7,978,447.

Discussion

Patients with PNES were found to have decreased health care utilization in the 12 months after referral to the Nationwide Children's Hospital multidisciplinary clinic, including significant decreases in emergency services and unnecessary diagnostic testing, in the 12 months after the referral.

Patient family engagement and partnership: Pilot survey results in assessing behavior, communication, and quality of life in children with Lennox-Gastaut syndrome and other drug-resistant epilepsy

OBJECTIVES

Lennox-Gastaut Syndrome (LGS) and other drug-resistant epilepsy (DRE) can impact behavior, communication, and quality of life (QoL). In collaboration with community engagement efforts with the Lennox-Gastaut Syndrome Foundation (LGSF), we aimed to gain an initial snapshot of patient and family perspectives and experiences with evaluation of behavior, communication, and QoL.

METHODS

A cross-sectional survey was conducted to collect self-reported information from caregivers of children with LGS and other DRE regarding their perspectives and experiences with healthcare providers' evaluation of behavior, communication, and QoL. The survey tool was developed by the study investigators in partnership with the LGS Foundation and had diffused to caregivers online by epilepsy advocacy groups including the Pediatric Epilepsy Surgery Alliance (PESA). Responses were analyzed. Descriptive statistics were calculated. The survey asked for caregiver perspectives and assessed which instruments the caregivers had previously been given for measuring these domains.

RESULTS

Responses from 245 caregivers were included, with 132 (54%) caregivers of an individual with LGS and 113 (46%) caregivers of an individual with non-LGS related DRE. Respondents reported that 66% of their loved ones had undergone epilepsy-related surgery. Over 90% agreed that measuring behavior, communication, and QoL was important, but fewer than half felt that their healthcare providers evaluated these domains well. LGS caregivers largely shared non-LGS caregivers' perspectives; however, they reported more frequently that communication was not evaluated enough. Barriers to measuring these domains included a lack of good surveys (developmentally appropriate and specific to the type of epilepsy) or not receiving any survey instruments for these domains during clinic appointments. Caregivers play a crucial role for individuals with DRE, and their input is essential in identifying challenges and needs. Caregivers believe that measuring behavior, communication, and quality of life is important, and most of them feel that their loved ones are not adequately evaluated during their healthcare encounters. There is a need for appropriately scaled survey instruments to measure areas of importance for patients and caregivers, as well as incorporation of these outcomes in the healthcare discussion.

Efficacy of cannabidiol in convulsive and nonconvulsive seizure types associated with treatment-resistant epilepsies in the Expanded Access Program

The cannabidiol (CBD) Expanded Access Program (EAP), initiated in 2014, provided CBD (Epidiolex) to patients with treatment-resistant epilepsy (TRE). In the final pooled analysis of 892 patients treated through January 2019 (median exposure = 694 days), CBD treatment was associated with a 46%-66% reduction in median monthly total (convulsive plus nonconvulsive) seizure frequency. CBD was well tolerated, and adverse events were consistent with previous findings. We used pooled EAP data to investigate the effectiveness of add-on CBD therapy for individual convulsive seizure types (clonic, tonic, tonic-clonic, atonic, focal to bilateral tonic-clonic), nonconvulsive seizure types (focal with and without impaired consciousness, absence [typical and atypical], myoclonic, myoclonic absence), and epileptic spasms. CBD treatment was associated with a reduction in the frequency of convulsive seizure types (median percentage reduction = 47%-100%), and nonconvulsive seizure types and epileptic spasms (median percentage reduction = 50%-100%) across visit intervals through 144 weeks of treatment. Approximately 50% of patients had ≥50% reduction in convulsive and nonconvulsive seizure types and epileptic spasms at nearly all intervals. These results show a favorable effect of long-term CBD use in patients with TRE, who may experience various convulsive and nonconvulsive seizure types. Future controlled trials are needed to confirm these findings.

Counseling on the Need for Folic Acid in Adolescents With Epilepsy

Background and Objectives

Folic acid is an important supplement to take for women with epilepsy on antiseizure medications (ASMs). Determination of baseline counseling given to women with epilepsy and the association with folic acid being recommended were evaluated. Factors surrounding the association were reviewed.

Methods

An exploratory retrospective review of women with epilepsy seen at a large Midwestern pediatric institution was performed between January 2018 and January 2020.

Results

Patients who received preconception counseling were more likely to be given a recommendation to take folic acid. Patients on more than 1 ASM were likely to receive counseling. Patient age and race were associated with having folic acid recommended.

Discussion

Providing preconception counseling for women with epilepsy is associated with an increased recommendation and prescription of folic acid. Further evaluation into possible disparities to receiving a folic acid recommendation is needed.

Implementing Evidence-Based, Electronic, Substance-Use Screening in a Primary Care Clinic

PURPOSE

Substance use is common among adolescents, and among those with substance use disorders; use often persists into middle age, underlying the importance of early detection and treatment. The goal of this quality improvement project was to increase the electronic substance use screening rate of adolescents presenting for preventative health visits from 0% to 50% between March 2021 and September 2021.

METHODS

This is an ongoing quality improvement project. Participants included patients ≥12 who presented to the Adolescent Medicine Clinic for preventative health visits. We incorporated the Screening to Brief Intervention into the existing Car, Relax, Alone, Forget, Friends, Trouble tool within the electronic health record. We completed a Plan-Do-Study-Act cycle by reviewing every patient's chart who did not receive screening and identified that a common reason for missed screening was designating the visit as "establishing care" rather than preventative health visit. We modified our eligible patient criteria to include all adolescents presenting to establish primary care.

RESULTS

We achieved a statistically significant center-line shift with a p value (<.001) from approximately 0% at baseline to a new baseline of 85% from June 2021 to June 2022. After broadening our eligibility criteria, our electronic screening rate improved from 78% in November 2021, to 83% in December 2021.

DISCUSSION

Electronic health record integration of the Screening to Brief Intervention/Car, Relax, Alone, Forget, Friends, Trouble is an effective method to systematically and electronically screen adolescents for SUD at preventative health visits. Integration using similar approaches may benefit other institutions interested in providing standardized SUD screening.

Self-management education for children with epilepsy and their caregivers. A scoping review

Self-management education programs have been highly successful in preparing people to manage medical conditions with recurring events. A detailed curriculum for epilepsy patients, and their caretakers, is lacking. Here we assess what is available for patients who have disorders with recurring events and offer an approach to developing a potential self-care curriculum for patients with seizures and their caregivers. Among the anticipated components are a baseline efficacy assessment and training tailored to increasing self-efficacy, medication compliance, and stress management. Those at risk of status epilepticus will also need guidance in preparing a personalized seizure action plan and training in how to decide when rescue medication is appropriate and how to administer the therapy. Peers, as well as professionals, could teach and provide support. To our knowledge, no such programs are currently available in English. We encourage their creation, dissemination, and widespread use.

Predictors of objective treatment adherence in adolescents with epilepsy: The important role of motivation

OBJECTIVE

Adolescents with epilepsy are at heightened risk for suboptimal anti-seizure medication (ASM) adherence; however, there is a paucity of adherence interventions for this age group. The current study aimed to identify a comprehensive and novel set of predictors of objective, electronically-monitored ASM adherence in adolescents with epilepsy.

METHODS

Participants included 104 adolescents (13-17 years old; M = 15.36 ± 1.40), diagnosed with epilepsy and their caregivers. Cross-sectional data were collected from adolescents, caregivers, healthcare providers, and medical chart reviews, including demographics (i.e., age, race/ethnicity, sex, insurance status), the COVID-19 pandemic (i.e., participation before versus during), seizure characteristics (i.e., presence and severity), ASM side effects (Pediatric Epilepsy Side Effects Questionnaire), adherence motivation (1-item 6-point Likert scale item), and adherence barriers (Pediatric Epilepsy Medication Self-Management Questionnaire). Electronically-monitored adherence data was collected via the AdhereTechTM pill bottle or the Vaica SimpleMedTM pillbox over 30 days.

RESULTS

Adolescents demonstrated suboptimal adherence at 78 ± 31.6%, despite high ASM adherence motivation (M = 4.43 ± .94) and minimal adherence barriers (M = 35.64 ± 3.78). Hierarchical multiple regression, which included non-modifiable sociodemographic and medical variables (Block 1) and behaviorally modifiable psychosocial variables (Block 2) was significant, F(12,87) = 3.69, p < .001. Specifically, having private insurance (versus Medicaid or public insurance; t = -2.11, p = .038) and higher adherence motivation (t = 2.91, p = .005) predicted higher objective ASM adherence.

CONCLUSION

Routine assessment of adherence predictors is vital for the promotion of adherence among adolescents with epilepsy. Adolescent adherence motivation may be an important element of multi-component interventions focused on improving ASM adherence in adolescents with epilepsy.

Pilot randomized controlled clinical trial of an adherence social norms intervention for adolescents with epilepsy

OBJECTIVE

Non-adherence to anti-seizure medications (ASMs) is common for adolescents with epilepsy, with potentially devastating consequences. Existing adherence interventions in epilepsy do not meet the unique challenges faced by adolescents. Leveraging social norms capitalizes on the increased importance of peer influence while simultaneously targeting the low motivation levels of many adolescents. The current study examined the feasibility, acceptability, and satisfaction of a social norms adherence intervention in adolescents with epilepsy.

METHODS

A pilot RCT of a mHealth social norms intervention was conducted with adolescents with epilepsy who demonstrated non-adherence (≤95% adherence) during baseline. Adolescents were randomized to either (1) mHealth social norms (reminders, individualized and social norms adherence feedback) or (2) control (reminders and individualized adherence feedback). Primary outcomes included feasibility, acceptability, and satisfaction. Exploratory outcomes included electronically monitored adherence, seizure severity, and health-related quality of life (HRQOL).

RESULTS

One hundred four adolescents were recruited (53% female; Mage = 15.4 ± 1.4 years; 81% White: Non-Hispanic; 5% Black, 10% Bi/Multiracial; 2% White: Hispanic; 1% Other: Hispanic; 1% Bi/Multiracial-Hispanic). Forty-five percent screen-failed due to high adherence, 16% withdrew, and 38% were randomized to treatment (n = 19) or control (n = 21). Recruitment (75%), retention (78%), and treatment satisfaction were moderately high. Engagement with the intervention was moderate, with 64% of participants engaging with intervention notifications. Exploratory analyses revealed that after controlling for COVID-19 impact, the social norms intervention group maintained higher adherence over time compared to the control group. Small to moderate effect sizes were noted for seizure severity and HRQOL between groups.

CONCLUSION

This pilot intervention appeared feasible and acceptable. Increases in adherence in the treatment versus control group were modest, but a future larger more adequately powered study is needed to detect effects. Notably, it appeared the COVID pandemic influenced adherence behaviors during our trial.

Long-term efficacy and safety of cannabidiol in patients with treatment-resistant epilepsies: Four-year results from the expanded access program

OBJECTIVE

Cannabidiol (CBD) expanded access program, initiated in 2014, provided add-on CBD to patients with treatment-resistant epilepsies (TREs) at 35 US epilepsy centers. Prior publications reported results through December 2016; herein, we present efficacy and safety results through January 2019.

METHODS

Patients received plant-derived highly purified CBD (Epidiolex®; 100 mg/ml oral solution), increasing from 2 to 10 mg/kg/day to tolerance or maximum 25-50 mg/kg/day dose, depending on the study site. Efficacy endpoints included percentage change from baseline in median monthly convulsive and total seizure frequency and ≥50%, ≥75%, and 100% responder rates across 12-week visit windows for up to 192 weeks. Adverse events (AEs) were documented at each visit.

RESULTS

Of 892 patients in the safety analysis set, 322 (36%) withdrew; lack of efficacy (19%) and AEs (7%) were the most commonly reported primary reasons for withdrawal. Median (range) age was 11.8 years (range = 0-74.5), and patients were taking a median of three (range = 0-10) antiseizure medications (ASMs) at baseline; the most common ASMs were clobazam (47%), levetiracetam (34%), and valproate (28%). Median top CBD dose was 25 mg/kg/day; median exposure duration was 694 days. Median percentage reduction from baseline ranged 50%-67% for convulsive seizures and 46%-66% for total seizures. Convulsive seizure responder rates (≥50%, ≥75%, and 100% reduction) ranged 51%-59%, 33%-42%, and 11%-17% of patients across visit windows, respectively. AEs were reported in 88% of patients and serious AEs in 41%; 8% withdrew because of an AE. There were 20 deaths during the study deemed unrelated to treatment by the investigator. The most common AEs (≥20% of patients) were diarrhea (33%), seizure (24%), and somnolence (23%).

SIGNIFICANCE

Add-on CBD was associated with sustained seizure reduction up to 192 weeks with an acceptable safety profile and can be used for long-term treatment of TREs.

Development of a core outcome set for quality of life for adults with drug-resistant epilepsy: A multistakeholder Delphi consensus study

OBJECTIVE

In 2017, the American Academy of Neurology (AAN) convened the AAN Quality Measurement Set working group to define the improvement and maintenance of quality of life (QOL) as a key outcome measure in epilepsy clinical practice. A core outcome set (COS), defined as an accepted, standardized set of outcomes that should be minimally measured and reported in an area of health care research and practice, has not previously been defined for QOL in adult epilepsy.

METHODS

A cross-sectional Delphi consensus study was employed to attain consensus from patients and caregivers on the QOL outcomes that should be minimally measured and reported in epilepsy clinical practice. Candidate items were compiled from QOL scales recommended by the AAN 2017 Quality Measurement Set. Inclusion criteria to participate in the Delphi study were adults with drug-resistant epilepsy diagnosed by a physician, no prior diagnosis of psychogenic nonepileptic seizures or a cognitive and/or developmental disability, or caregivers of patients meeting these criteria.

RESULTS

A total of 109 people satisfied inclusion/exclusion criteria and took part in Delphi Round 1 (patients, n = 95, 87.2%; caregivers, n = 14, 12.8%), and 55 people from Round 1 completed Round 2 (patients, n = 43, 78.2%; caregivers, n = 12, 21.8%). One hundred three people took part in the final consensus round. Consensus was attained by patients/caregivers on a set of 36 outcomes that should minimally be included in the QOL COS. Of these, 32 of the 36 outcomes (88.8%) pertained to areas outside of seizure frequency and severity.

SIGNIFICANCE

Using patient-centered Delphi methodology, this study defines the first COS for QOL measurement in clinical practice for adults with drug-resistant epilepsy. This set highlights the diversity of factors beyond seizure frequency and severity that impact QOL in epilepsy.

Introduction to use of an acute seizure action plan for seizure clusters and guidance for implementation

It is important for patients with epilepsy and their caregivers, including care partners, to understand the patient's seizure clusters and what to do when they occur. In many instances, seizure clusters are unique to each patient. The knowledge gained from understanding a patient's seizure cluster or seizure pattern provides a foundation for taking prompt action to prevent worsening to prolonged seizures, status epilepticus, and potentially death. Seizure action plans (SAPs), which are similar to the disease-related treatment action plans for other conditions, can be developed by a health care provider (HCP) in conjunction with the patient with epilepsy and/or caregivers, and SAPs are specifically customized for the individual patient and his or her seizure management. However, the current literature lacks unified guidance on how to design SAPs that will help prepare patients and caregivers for rapidly determining and initiating appropriate treatment of acute seizure emergencies in the community and at home. Here, we examine the current usage and value of SAPs for pediatric and adult patients with epilepsy, and we introduce the concept of the acute SAP (ASAP) for use specifically during seizure emergencies, such as seizure clusters. This type of standardized, simplified, and customized plan can rapidly and concisely provide patients and caregivers with a practical protocol to treat a seizure cluster consistently, appropriately, and in a timely manner. Details on potential content and formats of ASAPs are provided. Following this is a discussion of barriers to ASAP use that may affect HCPs or patients and caregivers, including lack of standardization, relevance, and personalization and pitfalls associated with technology. This leads into a discussion of guidance for developing, implementing, and updating ASAPs that suggests ways to address the barriers and ensure that the ASAP is best suited to the patient's needs.

Prioritizing Hormone Therapy Over Vigabatrin as the First Treatment for Infantile Spasms: A Quality Improvement Initiative

BACKGROUND AND OBJECTIVES

Infantile spasms (IS) are early childhood seizures with potentially devastating consequences. Standard therapies (adrenocorticotropic hormone [ACTH], high-dose prednisolone, and vigabatrin) are strongly recommended as the first treatment for IS. While this recommendation comes without preference for one standard therapy over another, early remission rates are higher with hormone therapy (ACTH and high-dose prednisolone) when compared to vigabatrin. Using quality improvement (QI) methodology that included hormone therapy as the first treatment, we sought to increase the percentage of children with new onset non-tuberous sclerosis complex (TSC)-associated IS achieving 3-month electroclinical remission from a mean of 53.8% to >70%.

METHODS

Observational cohort study using a consecutive sample at a single academic tertiary care hospital comparing a prospective intervention cohort (5/2019 - 1/2022, N = 57) to a retrospective baseline cohort (11/2015 - 4/2019, N = 67). Our initiative addressed key drivers such as the routine use of vigabatrin over hormone therapy as first treatment and the common initiation of a second treatment after 14 days for initial non-responders. We included consecutive children without TSC presenting with new onset IS diagnosed and treated between 2 - 24 months of age. We displayed our primary outcome and process measures as control charts in which the centerline is the quarterly (previous three months) mean based on statistical process control methodology.

RESULTS

QI interventions that included the standardization of hormone therapy as the first treatment resulted in higher rates of 3-month remission, rising from 53.8% (baseline cohort) to 75.9% (intervention cohort). Process measure results included an increased rate of children receiving hormone therapy as first treatment (mean 44.6% to 100%) as well as a decreased number of days to both clinical follow-up after first treatment (mean of 16.3 to 12.6 days) and starting a second treatment within 14 days for initial non-responders (mean of 36.3 to 17.2 days).

DISCUSSION

For children with IS, improved rates of 3-month electroclinical remission can be achieved with QI methodology. Implementation of similar QI initiatives at other centers may likewise improve local remission rates.

A Multicenter Study of Adherence to Best Practices and Application of Epilepsy Quality Metrics in a Pediatric Telemedicine Encounter

Objective: To assess Epilepsy Quality Metrics (EQM) and guideline implementation in new pediatric patients seen in telemedicine. Methods: Multicenter, cross sectional, retrospective analysis. Results: Patients were similar across 3 centers for age, gender, and insurance type. Eighty-one percent presented for spells. One hundred sixty patients with epilepsy formed the EQM cohort. Results: Seizures described: 95%; frequency: 67%, last seizure documented: 81%, epilepsy syndrome documented: 67%; epilepsy diagnosis: 77%, medications reviewed: 56%, adverse events discussed: 73%. Quality of life discussed: 3%. Anticipatory guidance was described as follows: seizure safety, 57%; driving, 47%; SUDEP, 11%; vitamin D discussion, 19%; pregnancy and folic acid counseling, 4% and 10%. Epileptologists were 4 times as likely as generalists in discussing driving safety (odds ratio 3.93, 95% confidence interval 1.7-8.9; P = .001) for all ages. Significance: Performance on EQM and guideline implementation in pediatric epilepsy telemedicine encounters can be improved.

Predicting Patient No-Shows in an Academic Pediatric Neurology Clinic

Background: No-shows can negatively affect patient care. Efforts to predict high-risk patients are needed. Previously, our epilepsy clinic identified patients with 2 or more no-shows or late cancelations in the past 18 months as being at high risk for no-shows. Our objective was to develop a model to accurately predict the risk of no-shows among patients with epilepsy seen at our neurology clinic. Methods: Using electronic health record data, we developed a least absolute shrinkage and selection operator (LASSO)-regularized logistic regression model to predict no-shows and compared its performance with our neurology clinic's above-mentioned ad hoc rule. Results: The ad hoc rule identified 13% of patients seen at our neurology clinic as high-risk patients for no-shows and resulted in a positive predictive value of 38%. In comparison, our LASSO model resulted in a positive predictive value of 48%. Our LASSO model identified that lack of private insurance, inactive Epic MyChart, greater past no-show rates, fewer appointment changes before the appointment date, and follow-up appointments were more likely to result in no-shows. Conclusions: Our LASSO model outperformed the ad hoc rule used by our neurology clinic in predicting patients at high risk for no-shows. Social workers can use the no-show risk scores generated by our LASSO model to prioritize high-risk patients for targeted intervention to reduce no-shows at our neurology clinic.

Biallelic SEPSECS variants in two siblings with pontocerebellar hypoplasia type 2D underscore the relevance of splice-disrupting synonymous variants in disease

Noncoding and synonymous coding variants that exert their effects via alternative splicing are increasingly recognized as an important category of disease-causing variants. In this report, we describe two siblings who presented with hypotonia, profound developmental delays, and seizures. Brain magnetic resonance imaging (MRI) in the proband at 5 yr showed diffuse cerebral and cerebellar white matter volume loss. Both siblings later developed ventilator-dependent respiratory insufficiency and scoliosis and are currently nonverbal and nonambulatory. Extensive molecular testing including oligo array and clinical exome sequencing was nondiagnostic. Research genome sequencing under an institutional review board (IRB)-approved study protocol revealed that both affected children were compound-heterozygous for variants in the SEPSECS gene. One variant was an initiator codon change (c.1A > T) that disrupted protein translation, consistent with the observation that most disease-causing variants are loss-of-function changes. The other variant was a coding change (c.846G > A) that was predicted to be synonymous but had been demonstrated to disrupt mRNA splicing in a minigene assay. The SEPSECS gene encodes O-phosphoseryl-tRNA(Sec) selenium transferase, an enzyme that participates in the biosynthesis and transport of selenoproteins in the body. Variations in SEPSECS cause autosomal recessive pontocerebellar hypoplasia type 2D (PCHT 2D; OMIM #613811), a neurodegenerative condition characterized by progressive cerebrocerebellar atrophy, microcephaly, and epileptic encephalopathy. The identification of biallelic pathogenic variants in this family—one of which was a synonymous change not identified by prior clinical testing—not only ended the diagnostic odyssey for this family but also highlights the contribution of occult pathogenic variants that may not be recognized by standard genetic testing methodologies.

Pediatric Epilepsy Learning Healthcare System Quality of Life (PELHS-QOL-2): A novel health-related quality of life prompt for children with epilepsy

OBJECTIVE

Pediatric epilepsy is often associated with diminished health-related quality of life (HRQOL). Our aim was to establish the validity of the Pediatric Epilepsy Learning Healthcare System Quality of Life (PELHS-QOL-2) questions, a novel two-item HRQOL prompt for children with epilepsy, primarily for use in clinical care.

METHODS

We performed a multicenter cross-sectional study to validate the PELHS-QOL-2. Construct validity was established through bivariate comparisons with four comparator measures and known drivers of quality of life in children with epilepsy, as well as by creating an a priori multivariable model to predict the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE-55). Validity generalization was established through bivariate comparisons with demographic and clinical information. Content validity and clinical utility were established by assessing how well the PELHS-QOL-2 met eight design criteria for an HRQOL prompt established by a multistakeholder group of experts.

RESULTS

The final participant sample included 154 English-speaking caregivers of children with epilepsy (mean age = 9.7 years, range = .5-18, 49% female, 70% White). The PELHS-QOL-2 correlated with the four comparator instruments (ρ = .44-.56), was significantly associated with several known drivers of quality of life in children with epilepsy (p < .05), and predicted QOLCE-55 scores in the multivariate model (adjusted R² = .54). The PELHS-QOL-2 item was not associated with the age, sex, and ethnicity of the children nor with the setting and location of data collection, although PELHS-QOL-Medications was significantly associated with race (worse for White race). Following both quantitative and qualitative analysis, the PELHS-QOL-2 met seven of eight design criteria.

SIGNIFICANCE

The PELHS-QOL-2 is a valid HRQOL prompt and is well suited for use in clinical care as a mechanism to routinely initiate conversations with caregivers about quality of life in children with epilepsy. The association of PELHS-QOL-Medications with race merits further study.

Decreasing Emergency Department Visits for Children With Epilepsy

Background and Objectives

Epilepsy and seizures represent a frequent cause of emergency department (ED) visits for patients. By implementing quality improvement (QI) methodology, we planned to decrease ED visits for children and adolescents with epilepsy.

Methods

In 2016, a multidisciplinary team was created to implement QI methodology to address ED visits for patients with epilepsy. Based on previous successes, further ED visit reduction was deemed possible. Our aim statement was to decrease the number of ED visits, per 1000 established patients with epilepsy, from 13.03 to 11.6, by December 2019 and sustain for 1 year.

Results

We successfully decreased ED visits for seizure-related care in patients with epilepsy from 13.03% to 10.2% per 1,000 patients, which resulted in a centerline shift.

Discussion

Using QI methodology, we improved the outcome measure of decreasing ED visits for children with epilepsy. Implementations of these interventions can be considered at other institutions that may lead to similar results.

COVID-19 and Vaccination in the Setting of Neurologic Disease: An Emerging Issue in Neurology

The COVID-19 pandemic caused by the SARS-CoV-2 virus has left many unanswered questions for patients with neurological disorders and the providers caring for them. Elderly and immunocompromised patients are at increased risk for severe symptoms due to COVID-19, and the virus may increase symptoms of underlying neurological illness, particularly for those with significant bulbar and respiratory weakness or other neurologic disability. Emerging SARS-CoV-2 vaccines offer substantial protection from symptomatic infection, but both patients and providers may have concerns regarding theoretical risks of vaccination, including vaccine safety and efficacy in the context of immunotherapy and the potential for precipitating or exacerbating neurological symptoms. In this statement on behalf of the Quality Committee of the AAN we review the current literature, focusing on COVID-19 infection in adults with neurological disease, in order to elucidate risks and benefits of vaccination in these individuals. Based on existing evidence, neurologists should recommend COVID-19 vaccination to their patients. For those patients being treated with immunotherapies, attention should be paid to timing of vaccination with respect to treatment and the potential for an attenuated immune response.

Recommendations for development of acute seizure action plans (ASAPs) from an expert panel

PURPOSE OF REVIEW

Disease-related treatment action plans for acute exacerbations providing information that may be helpful for self-management for patients and caregivers are commonly used for chronic conditions such as asthma and diabetes. However, among patients with epilepsy, a review of the literature suggested that the majority did not have an action plan in place for acute seizure treatment.

RECENT FINDINGS

Currently, there is a lack of unified guidance on seizure action plans (SAPs) in the literature. In the authors' opinion, available formats have limitations for practical use and may not be easily customizable to individual patients, and they are not often designed to provide simple-to-follow steps for rapid immediate steps to determine and initiate appropriate treatment of seizure emergencies. Our group reviewed current examples of SAPs and provided guidance on the development of acute seizure action plans (ASAPs) designed to facilitate rapid, appropriate acute care in the community and to be as useful as possible for a wide range of care partners, including those with limited experience.

SUMMARY

This paper provides agreed upon expert opinion recommendations and considerations for goals, development process, types of content, and format for an ASAP.

Impact of intellectual and developmental disability on quality-of-life priorities in adults with epilepsy

OBJECTIVE

Adults living with intellectual and developmental disability (IDD) and epilepsy (IDD-E) face challenges in addition to those faced by the general population of adults with epilepsy, which may be associated with distinct priorities for improving health-related quality of life (HR-QOL). This study sought to (1) conduct a survey of HR-QOL priorities identified by adults with IDD-E and caregivers, and (2) perform an exploratory cross-sectional comparison to adults with epilepsy who do not have IDD.

METHODS

This cross-sectional study recruited 65 adults with IDD-E and 134 adults with epilepsy without IDD and caregivers. Using a three-step development process, 256 items from existing quality-of-life scales recommended by the American Academy of Neurology (AAN) were rated by patients/caregivers for their importance as HR-QOL priorities. HR-QOL items identified as critical to the majority of the sample of adults with IDD-E were reported. Health-related quality of life priorities were compared between adults with IDD-E and adults with epilepsy without IDD.

RESULTS

Health-related quality of life was significantly lower in adults with IDD-E. Health-related quality of life domains identified as critical priorities by adults with IDD-E included seizure burden, anti-seizure medication side effects, seizure unpredictability, and family impact. Priorities for improving HR-QOL differed between adults with and without IDD-E, with concerns about family impact, difficulty finding appropriate living conditions, inadequate assistance, and difficulty transitioning from pediatric-to-adult care valued significantly more among those with IDD-E.

SIGNIFICANCE

Intellectual and developmental disability is an important determinant of HR-QOL among adults with epilepsy. We report HR-QOL priorities identified by adults with IDD-E and their caregivers. These results may help epilepsy clinicians and researchers develop tailored strategies to address priorities of the patient with IDD-E/caregiver community.

Comparative Effectiveness of Initial Treatment for Infantile Spasms in a Contemporary US Cohort

OBJECTIVE

To compare the effectiveness of initial treatment for infantile spasms.

METHODS

The National Infantile Spasms Consortium prospectively followed up children with new-onset infantile spasms that began at age 2 to 24 months at 23 US centers (2012-2018). Freedom from treatment failure at 60 days required no second treatment for infantile spasms and no clinical spasms after 30 days of treatment initiation. We managed treatment selection bias with propensity score weighting and within-center correlation with generalized estimating equations.

RESULTS

Freedom from treatment failure rates were as follows: adrenocorticotropic hormone (ACTH) 88 of 190 (46%), oral steroids 42 of 95 (44%), vigabatrin 32 of 87 (37%), and nonstandard therapy 4 of 51 (8%). Changing from oral steroids to ACTH was not estimated to affect response (observed 44% estimated to change to 44% [95% confidence interval 34%-54%]). Changing from nonstandard therapy to ACTH would improve response from 8% to 39% (17%-67%), and changing to oral steroids would improve response from 8% to 38% (15%-68%). There were large but not statistically significant estimated effects of changing from vigabatrin to ACTH (29% to 42% [15%-75%]), from vigabatrin to oral steroids (29% to 42% [28%-57%]), and from nonstandard therapy to vigabatrin (8% to 20% [6%-50%]). Among children treated with vigabatrin, those with tuberous sclerosis complex (TSC) responded more often than others (62% vs 29%; p < 0.05).

DISCUSSION

Compared to nonstandard therapy, ACTH and oral steroids are superior for initial treatment of infantile spasms. The estimated effectiveness of vigabatrin is between that of ACTH/oral steroids and nonstandard therapy, although the sample was underpowered for statistical confidence. When used, vigabatrin worked best for TSC.

CLASSIFICATION OF EVIDENCE

This study provides Class III evidence that for children with new-onset infantile spasms, ACTH or oral steroids were superior to nonstandard therapies.

Improving time for administration of second-line antiseizure medications for children with generalized convulsive status epilepticus using quality improvement methodology

OBJECTIVE

Status epilepticus is a life-threatening neurological emergency. However, delay in median time to administration of second-line antiseizure medication exists. The aim of this quality improvement initiative was to decrease the average delay before fosphenytoin is administered for pediatric patients with generalized convulsive status epilepticus from 30 min (baseline data collected in 2013) to 15 min (50% reduction) by December 2015 and sustain this for 1 year.

METHODS

Our team conducted an analysis of baseline data for patients with continuous generalized convulsive status epilepticus who received fosphenytoin after receiving first-line benzodiazepine treatment. Using quality improvement methodology, areas for improvement were identified and specific interventions developed and implemented. A timeline of 15 min to initiate fosphenytoin administration after failure of first-line treatment was considered reasonable and achievable as a project aim.

RESULTS

A total of 199 patients were included in the dataset for the project. The database included patients aged 1 month and older. Ninety-eight percent of patients were between 1 month and 19 years of age. The gender distribution was even, with 54% of patients being White or Caucasian, 30% African American or Black, and 16% classified as "other." From January 2014 through December 2019, the average time before initiating fosphenytoin administration after failure of benzodiazepine therapy, for patients with generalized convulsive status epilepticus, decreased from 30 min (SD = 45.7) to 11.4 min (SD = 8.2, p = .043), thus reducing time to administration by 62%.

SIGNIFICANCE

Quality improvement methodology can be successfully applied to decrease administration time between first- and second-line antiseizure medications for status epilepticus.

Medication selection, health services outcomes, and cost trajectories for Medicaid beneficiaries with infantile spasms

OBJECTIVE

There are three recommended first-line treatments for infantile spasms, adrenocorticotropic hormone (ACTH), oral corticosteroids, and vigabatrin, though non-standard treatments such as topiramate are sometimes selected. Is it uncertain how treatment selection influences health services outcomes.

METHODS

We conducted a retrospective cohort study of Medicaid beneficiaries newly diagnosed with infantile spasms from 2009-2010. We included infants with a new diagnosis of infantile spasms between age 2-9 months who filled ACTH (reference), prednisolone, vigabatrin, or topiramate prescriptions. Multivariable Cox proportional hazards regression compared time to first emergency department (ED) visit or hospitalization across treatment groups during 2 years of follow-up. Monthly costs for each treatment were examined in 6-month intervals and compared in a multivariable generalized linear model.

RESULTS

Among 256 children with infantile spasms, 116 received ACTH, 62 prednisolone, 15 vigabatrin, and 63 topiramate. The rate of ED visit or hospitalization per person-year did not differ significantly for prednisolone (0.9 [95 % CI 0.7-1.2]; adjusted hazard ratio [aHR] 0.84, 95 % CI 0.57-1.24), vigabatrin (0.8 [95 % CI 0.4-1.5]; aHR 0.91, 95% CI 0.45-1.84), or topiramate (1.7 [95 % CI 1.3-2.3]; aHR 1.15, 95 % CI 0.80-1.65), when compared to ACTH (1.1 [95 % CI 0.9-1.3]). The median payment for ACTH was $96,406 (interquartile range 70,742-138,476) during the first 6 months. The adjusted mean total payment in the first 6 months was 73% lower for prednisolone (95% CI -82, -61), 69% lower for vigabatrin (95% CI -84, -40), and 73% lower for topiramate (95% CI -82, -59). However, in subsequent 6-month intervals, costs associated with ACTH were not significantly different compared to other treatments.

SIGNIFICANCE

Compared to other treatments for infantile spasms, use of ACTH was associated with greater cost in the first 6 months of treatment, but not with reduced ED visits or hospitalizations. The cost effectiveness of ACTH depends on its relative clinical efficacy, and merits additional research.

Long-term safety and efficacy of add-on cannabidiol in patients with Lennox-Gastaut syndrome: Results of a long-term open-label extension trial

OBJECTIVE

Lennox-Gastaut syndrome (LGS) is an epileptic encephalopathy that is often treatment resistant. Efficacy and safety of add-on cannabidiol (CBD) to treat seizures associated with LGS was demonstrated in two randomized controlled trials (RCTs). Patients who completed the RCTs were invited to enroll in this long-term open-label extension (OLE) trial, GWPCARE5 (NCT02224573). We present the final analysis of safety and efficacy outcomes from GWPCARE5.

METHODS

Patients received plant-derived highly purified CBD (Epidiolex in the United States; Epidyolex in the European Union; 100 mg/ml oral solution), titrated to a target maintenance dose of 20 mg/kg/day over 2 weeks. Based on response and tolerability, CBD could then be reduced or increased up to 30 mg/kg/day.

RESULTS

Of 368 patients with LGS who completed the RCTs, 366 (99.5%) enrolled in this OLE. Median and mean treatment duration were 1090 and 826 days (range = 3-1421), respectively, with a mean modal dose of 24 mg/kg/day. Adverse events (AEs) occurred in 96% of patients, serious AEs in 42%, and AE-related discontinuations in 12%. Common AEs were convulsion (39%), diarrhea (38%), pyrexia (34%), and somnolence (29%). Fifty-five (15%) patients experienced liver transaminase elevations more than three times the upper limit of normal; 40 (73%) were taking concomitant valproic acid. Median percent reductions from baseline ranged 48%-71% for drop seizures and 48%-68% for total seizures through 156 weeks. Across all 12-week visit windows, 87% or more of patients/caregivers reported improvement in the patient's overall condition on the Subject/Caregiver Global Impression of Change scale.

SIGNIFICANCE

Long-term add-on CBD treatment had a similar safety profile as in the original RCTs. Sustained reductions in drop and total seizure frequency were observed for up to 156 weeks, demonstrating long-term benefits of CBD treatment for patients with LGS.

The psychosocial impact of COVID-19 within the first six months of the pandemic on youth with epilepsy and their caregivers

OBJECTIVES

We assessed the impact of COVID-19 on children with epilepsy and their families, focusing on epilepsy management, family routines, learning, and adherence to Centers for Disease Control and Prevention (CDC) pandemic guidelines (e.g., social distancing, mask wearing) within the first six months of the pandemic. Group differences in COVID-19 impact on families were also examined based on race and ethnicity, being medically and/or geographically underserved, and insurance status.

METHODS

Participants (n = 131) included children with epilepsy and their families from two clinical trials. The Impact of COVID-19 on Pediatric Epilepsy Management (ICPEM) measure was developed and administered to caregivers online from April 2020 to September 2020 across four large pediatric hospitals. Administration of the ICPEM occurred both during routine study assessments and an additional acute time point to obtain information early in the pandemic (e.g., April and May 2020). Descriptive statistics and t-tests were used for analyses.

RESULTS

Data indicate minor to moderate impact of COVID-19 on pediatric epilepsy management. Caregivers of children with epilepsy reported the most impact on education and social functioning. Adherence to CDC guidelines was reported to be high. Those having public insurance reported greater difficulties obtaining daily anti-seizure medications compared to those with private insurance.

CONCLUSIONS

This study presents important initial data regarding the impact of COVID-19 epilepsy management and daily functioning in children with epilepsy and their families. While the acute impact of COVID-19 restrictions appear to be mild to moderate, it is unclear what the long-term impact of the pandemic will be on families of children with epilepsy.

Evaluation of a Care Management Program for Pediatric Epilepsy Patients

OBJECTIVE

To evaluate the impact of a pediatric epilepsy care management intervention on emergency department visits, hospitalizations, and seizure freedom.

METHODS

We conducted a prospective observational study at a single academic medical center. Children with epilepsy with high risk of frequent emergency department use were enrolled in the intervention from January through May 2015, which included a baseline visit and follow-up support from a care management team. Controls selected from the same institution received standard of care. Baseline and follow-up information were collected from electronic health records and surveys (Family Impact Scale, Pediatric Epilepsy Medication Self-Management Questionnaire). Propensity score-weighted logistic regression compared emergency department visits, unplanned hospitalizations, and 3-month seizure freedom after 1 year in the intervention vs control groups.

RESULTS

A total of 56 children were enrolled in the intervention and 359 received standard of care. The intervention group was younger and had greater use of health services at baseline. When comparing the intervention to standard of care after 1 year, we found no significant difference in the risk of any emergency department visit (adjusted odds ratio [OR] 2.2, 95% confidence interval [CI] 0.6-8.5) or seizure freedom (adjusted OR 2.5, 95% CI 0.3-21.5). However, the risk of unplanned hospital admissions remained higher in the intervention group (adjusted OR 23.1, 95% CI 5.1-104).

CONCLUSION

We did not find that children with epilepsy who received a care management intervention had less use of health services or better clinical outcomes after a year compared with controls. The study is limited by small sample size and nonrandomized study design.

Improving Patient-Centered Communication about Sudden Unexpected Death in Epilepsy through Computerized Clinical Decision Support

BACKGROUND

Sudden unexpected death in epilepsy (SUDEP) is a rare but fatal risk that patients, parents, and professional societies clearly recommend discussing with patients and families. However, this conversation does not routinely happen.

OBJECTIVES

This pilot study aimed to demonstrate whether computerized decision support could increase patient communication about SUDEP.

METHODS

A prospective before-and-after study of the effect of computerized decision support on delivery of SUDEP counseling. The intervention was a screening, alerting, education, and follow-up SUDEP module for an existing computerized decision support system (the Child Health Improvement through Computer Automation [CHICA]) in five urban pediatric primary care clinics. Families of children with epilepsy were contacted by telephone before and after implementation to assess if the clinician discussed SUDEP at their respective encounters.

RESULTS

The CHICA-SUDEP module screened 7,154 children age 0 to 21 years for seizures over 7 months; 108 (1.5%) reported epilepsy. We interviewed 101 families after primary care encounters (75 before and 26 after implementation) over 9 months. After starting CHICA-SUDEP, the number of caregivers who reported discussing SUDEP with their child's clinician more than doubled from 21% (16/75) to 46% (12/26; p = 0.03), and when the parent recalled who brought up the topic, 80% of the time it was the clinician. The differences between timing and sampling methodologies of before and after intervention cohorts could have led to potential sampling and recall bias.

CONCLUSION

Clinician-family discussions about SUDEP significantly increased in pediatric primary care clinics after introducing a systematic, computerized screening and decision support module. These tools demonstrate potential for increasing patient-centered education about SUDEP, as well as incorporating other guideline-recommended algorithms into primary and subspecialty cares.

The development of a social norms adherence intervention for adolescents with epilepsy

INTRODUCTION

Adherence is suboptimal in adolescents with epilepsy. Social norms comparison (i.e., feedback about someone else's behavior related to one's own behavior) strategies may be beneficial in improving medication adherence. Using a novel model of behavioral intervention development, the aim of the current study was to create a social norms intervention for adolescents with epilepsy via focus groups and usability studies.

METHODS

A focus group, individual interviews, short-term usability, and extended usage testing studies were conducted. Across all study phases, content and images of intervention components were displayed to participants as mock-ups in PowerPoint slide decks. After each phase, updated iterations were shown to participants to refine the intervention. Several questionnaires were completed by adolescents and caregivers to characterize the samples.

RESULTS

Twelve adolescents participated in the focus group/individual interviews and usability studies. The final Behavioral Economic Adherence for Teens (BEAT) intervention consists of a text messaging system and a graphical user interface. General feedback indicated the need for simplicity and ease of use regarding obtaining the graphical messages (e.g., no extra login and passwords); engaging visual images; and weekly comparisons of a target patient's medication adherence to other adolescents' performance. The average system usability system (SUS) rating was 88.3 + 3.8.

CONCLUSIONS

Our final intervention had high usability ratings and was perceived as engaging and easy to understand. An important next step is to test the BEAT intervention in a Phase 2 randomized trial.

Validating Coding for the Identification of Pediatric Treatment Resistant Epilepsy Patients

The International Classification of Diseases (ICD) system includes sub codes to indicate that an individual with epilepsy is treatment resistant. These codes would be a valuable tool to identify individuals for quality improvement and population health, as well as for recruitment into clinical trials. However, the accuracy of these codes is unclear. We performed a single center cross sectional study to understand the accuracy of ICD codes for treatment resistant epilepsy. We identified 344 individuals, roughly half with treatment resistant epilepsy The ICD code had a sensitivity of 90% (147 of 164) and specificity of 86% (155 of 180). The miscoding of children with refractory epilepsy was attributed to the following reasons: 5 patients had epilepsy surgery, 4 had absence epilepsy, 4 patients were seen by different providers, and 1 patient was most recently seen in movement disorders clinic. ICD codes accurately identify children with treatment resistant epilepsy.

Design and implementation of electronic health record common data elements for pediatric epilepsy: Foundations for a learning health care system

OBJECTIVE

Common data elements (CDEs) are standardized questions and answer choices that allow aggregation, analysis, and comparison of observations from multiple sources. Clinical CDEs are foundational for learning health care systems, a data-driven approach to health care focused on continuous improvement of outcomes. We aimed to create clinical CDEs for pediatric epilepsy.

METHODS

A multiple stakeholder group (clinicians, researchers, parents, caregivers, advocates, and electronic health record [EHR] vendors) developed clinical CDEs for routine care of children with epilepsy. Initial drafts drew from clinical epilepsy note templates, CDEs created for clinical research, items in existing registries, consensus documents and guidelines, quality metrics, and outcomes needed for demonstration projects. The CDEs were refined through discussion and field testing. We describe the development process, rationale for CDE selection, findings from piloting, and the CDEs themselves. We also describe early implementation, including experience with EHR systems and compatibility with the International League Against Epilepsy classification of seizure types.

RESULTS

Common data elements were drafted in August 2017 and finalized in January 2020. Prioritized outcomes included seizure control, seizure freedom, American Academy of Neurology quality measures, presence of common comorbidities, and quality of life. The CDEs were piloted at 224 visits at 10 centers. The final CDEs included 36 questions in nine sections (number of questions): diagnosis (1), seizure frequency (9), quality of life (2), epilepsy history (6), etiology (8), comorbidities (2), treatment (2), process measures (5), and longitudinal history notes (1). Seizures are categorized as generalized tonic-clonic (regardless of onset), motor, nonmotor, and epileptic spasms. Focality is collected as epilepsy type rather than seizure type. Seizure frequency is measured in nine levels (all used during piloting). The CDEs were implemented in three vendor systems. Early clinical adoption included 1294 encounters at one center.

SIGNIFICANCE

We created, piloted, refined, finalized, and implemented a novel set of clinical CDEs for pediatric epilepsy.

Cannabinoids in Neurologic Illnesses

Marijuana has been used to treat medical disease since well before the 1800s. Recently, increased use of cannabinoids, the chemical components of marijuana, have been seen to treat neurologic illness in children and adults. Unfortunately, data are lacking in treating most neurologic illnesses except in the field of epilepsy and pain from spasticity in multiple sclerosis. Therefore, formal conclusions about the potential efficacy, benefit, and adverse effects for most marijuana based products cannot be made at this time. Further research using gold standard scientific methodology should be performed to help address potential uses and safety for cannabinoids to treat neurologic illnesses.

Care Delivery for Children With Epilepsy During the COVID-19 Pandemic: An International Survey of Clinicians

OBJECTIVE

To evaluate the effect of the COVID-19 pandemic on global access to care and practice patterns for children with epilepsy.

METHODS

We conducted a cross-sectional, online survey of pediatric neurologists across the world affiliated with the International Child Neurology Association, the Chinese Child Neurology Society, the Child Neurology Society, and the Pediatric Epilepsy Research Consortium. Results were analyzed in relation to regional burden of COVID-19 disease.

RESULTS

From April 10 to 24, 2020, a sample of 212 respondents from 49 countries indicated that the COVID-19 pandemic has dramatically changed many aspects of pediatric epilepsy care, with 91.5% reporting changes to outpatient care, 90.6% with reduced access to electroencephalography (EEG), 37.4% with altered management of infantile spasms, 92.3% with restrictions in ketogenic diet initiation, 93.4% with closed or severely limited epilepsy monitoring units, and 91.3% with canceled or limited epilepsy surgery. Telehealth use had increased, with 24.7% seeing patients exclusively via telehealth. Changes in practice were related both to COVID-19 burden and location.

CONCLUSIONS

In response to COVID-19, pediatric epilepsy programs have implemented crisis standards of care that include increased telemedicine, decreased EEG use, changes in treatments of infantile spasms, and cessation of epilepsy surgery. The long-term impact of these abrupt changes merit careful study.

Evaluation of an Activity Tracker to Detect Seizures Using Machine Learning

Currently, the tracking of seizures is highly subjective, dependent on qualitative information provided by the patient and family instead of quantifiable seizure data. Usage of a seizure detection device to potentially detect seizure events in a population of epilepsy patients has been previously done. Therefore, we chose the Fitbit Charge 2 smart watch to determine if it could detect seizure events in patients when compared to continuous electroencephalographic (EEG) monitoring for those admitted to an epilepsy monitoring unit. A total of 40 patients were enrolled in the study that met the criteria between 2015 and 2016. All seizure types were recorded. Twelve patients had a total of 53 epileptic seizures. The patient-aggregated receiver operating characteristic curve had an area under the curve of 0.58 [0.56, 0.60], indicating that the neural network models were generally able to detect seizure events at an above-chance level. However, the overall low specificity implied a false alarm rate that would likely make the model unsuitable in practice. Overall, the use of the Fitbit Charge 2 activity tracker does not appear well suited in its current form to detect epileptic seizures in patients with seizure activity when compared to data recorded from the continuous EEG.

Using quality improvement to implement the CNS/AAN quality measure on rescue medication for seizures

OBJECTIVE

A multidisciplinary quality improvement (QI) team was established to conduct analysis of data for prescribed seizure rescue medication doses from January 2013 to December 2015 to identify and improve inappropriately low dose prescriptions. The QI team identified areas of focus for improvement opportunities and developed the project objective based on the 2017 American Academy of Neurology (AAN) and Child Neurology Society (CNS) quality measure.

METHODS

Within a freestanding children's hospital, the QI team developed key drivers and implemented interventions, such as the midazolam prefilled syringe program with use of standardized dosing, electronic chart tools, monthly pharmacy review of all underdosed prescriptions, and provider and nursing education. The team created an automated monthly report to monitor prescribed seizure rescue medication dosing compliance. The year 2015 was used as the preliminary data baseline period with an average noncompliance rate of 3.5%.

RESULTS

From January 2016 to December 2019, the team has decreased and sustained the noncompliance rate to an average of 0.38%. The data for the project included 12,975 seizure rescue medication prescribed by a neurology provider from January 2015 to December 2019. Compliance with properly dosed diazepam orders continues to be the largest area of opportunity. The data demonstrated a centerline shift in January 2019, moving the baseline average of 7.2% noncompliance to the current average rate of 0.22%. In comparison, underdosed midazolam orders occurred at an average rate of 0.037% in the same timeframe.

SIGNIFICANCE

Using quality improvement methodologies, the team successfully and substantially decreased provider prescribed and signed underdosed rescue medication orders by an average of 89%. This QI project demonstrates successful implementation and improvement addressing the AAN/CNS quality measure of proper rescue seizure treatment dosing.

Measuring the impact of epilepsy on families

OBJECTIVE

Caring for a child with illness or a child with disability impacts family in various ways. The ability to assess the impact of this care on families is one way to proactively provide the necessary support and resources for impacted families. Accordingly, the goal of the current study was to assess the impact of pediatric epilepsy on individual families in a comprehensive epilepsy clinic using a slightly modified version of the Impact on Families Scale (IFS).

METHODS

Families of patients with epilepsy completed the IFS up to three times. The IFS score and the six categories (i.e., total impact, financial impact, general impact, family/social impact, coping, and sibling impact) were assessed using Student's two sample t-test to determine the differences between binary groups and Pearson's correlation to assess the associations with continuous variables. Linear regression modeling was used to develop a model to predict IFS score.

RESULTS

Three hundred and forty-one patients completed the scale at one time point, 314 at two time points, and 61 at three time points. The overall impact of epilepsy on families was 109 (95% confidence interval (CI): 106-112) at time point 1, 111 (95% CI: 108-114) at time point 2, and 112 (95% CI: 105-119) at time point 3. There was no statistical difference in IFS score among the three time points. There were no associations with age or gender. Multivariable modeling using stepwise regression indicated that treatment resistance and seizure-free status were associated with IFS score. No interaction effects were identified.

CONCLUSIONS

Findings from the current study suggest that the impact of epilepsy is highest for families that have children with active seizures at the time of their clinical visit and for those with children having treatment-resistant epilepsy. Although intuitive, this is the first study, to our knowledge, that has empirically verified these findings.

Management of Infantile Spasms During the COVID-19 Pandemic

Circumstances of the COVID-19 pandemic have mandated a change to standard management of infantile spasms. On April 6, 2020, the Child Neurology Society issued an online statement of immediate recommendations to streamline diagnosis and treatment of infantile spasms with utilization of telemedicine, outpatient studies, and selection of first-line oral therapies as initial treatment. The rationale for the recommendations and specific guidance including follow-up assessment are provided in this manuscript. These recommendations are indicated as enduring if intended to outlast the pandemic, and limited if intended only for the pandemic health care crisis but may be applicable to future disruptions of health care delivery.

Validation of EpiTRAQ, a transition readiness assessment tool for adolescents and young adults with epilepsy

OBJECTIVE

To design and validate a transition readiness assessment tool for adolescents and young adults with epilepsy and without intellectual disability.

METHODS

We adapted a general transition readiness assessment tool (TRAQ) to add epilepsy-relevant items based on concepts in current epilepsy quality measures. The adapted tool, EpiTRAQ, maintained the original structure and scoring system. Concurrent with clinical implementation in pediatric and adult epilepsy clinics at an academic medical center, we assessed the validity and reliability of this adapted tool for patients 16-26 years of age. This process included initial validation with 302 patients who completed EpiTRAQ between October 2017 and May 2018; repeat validation with 381 patients who completed EpiTRAQ between June 2018 and September 2019; and retest reliability among 153 patients with more than one completed EpiTRAQ.

RESULTS

Mean scores were comparable between initial and repeat validation populations (absolute value differences between 0.05 and 0.1); internal consistency ranged from good to high. For both the initial and repeat validation, mean scores and internal consistency demonstrated high comparability to the original TRAQ validation results. Upon retest, few patients rated themselves with a lower score, while the majority rated themselves with higher scores.

SIGNIFICANCE

EpiTRAQ is a valid and reliable tool for assessing transition readiness in adolescents and young adults with epilepsy and without intellectual disability.

Continued Gap in Seizure Frequency Documentation

Proper documentation during neurology clinic visits is essential. Medical providers that document precise and standardized findings aid other providers, nurses, and research personnel. The American Academy of Neurology (AAN) created standardized quality measures in order to improve delivery of care for patients with epilepsy, providers, and systems. In this article, we reviewed a total of 777 charts in order to find documentation on seizure frequency from the most recent clinical visit. Data was collected from electronic healthcare records. During initial chart review, the following information was noted: age, gender, seizure type(s), etiology type(s), provider (neurologist or epileptologist), whether seizure frequency was noted, and the reason for no documentation. The data review represented a sample of the epilepsy population seen at our institution. Of the 734 individuals, 475 patients had seizure frequency documented (65%). Two hundred and fifty-nine (259) people (35%) were missing seizure frequency data. For those individuals, we determined the reasoning behind why this data was not present in the chart note. Of those 259 charts, there were 65 (25%) charts missing seizure frequency, 161 (62%) charts that were vague, and 33 (13%) charts where seizure frequency could not be determined. Based on our findings, the documentation of seizure frequency is a gap in care.

Posttraumatic Subacute Effusive-Constrictive Pericarditis After a Motor Vehicle Accident

Effusive-constrictive pericarditis is typically caused by tuberculosis or other severe inflammatory conditions that affect the pericardium. We report a case of effusive-constrictive pericarditis consequent to a motor vehicle accident. A 32-year-old man with gastroesophageal reflux disease presented with severe substernal chest pain of a month's duration and dyspnea on exertion for one week. Echocardiograms revealed a moderate pericardial effusion, and the diagnosis was subacute effusive-constrictive pericarditis. After thorough tests revealed nothing definitive, we learned that the patient had been in a motor vehicle accident weeks before symptom onset, which made blunt trauma the most likely cause of pericardial injury and effusion. Medical management resolved the effusion and improved his symptoms. To our knowledge, this is the first report of effusion from posttraumatic constrictive pericarditis associated with a motor vehicle accident. We encourage providers to consider recent trauma as a possible cause of otherwise idiopathic pericarditis.

Seizure detection devices and health-related quality of life: A patient- and caregiver-centered evaluation

INTRODUCTION

The unpredictability of epilepsy has a severe impact on health-related quality of life (HR-QOL) for people with epilepsy. Seizure detection devices have the potential to improve HR-QOL by improving seizure safety, reducing caregiver hypervigilance, and reducing seizure anxiety. Emerging data have led to an improved understanding of characteristics that promote acceptability of detection devices for people with epilepsy and caregivers. However, whether usage of seizure detection devices is associated with clinically meaningful improvement in anxiety and HR-QOL remains poorly understood.

METHODS

We analyzed cross-sectional survey data collected first-hand from 371 people with epilepsy and caregivers on seizure detection device and HR-QOL using an enriched population of electronic seizure diary users. Metrics related to quality of life and anxiety reduction were compared between users and nonusers of seizure detection devices.

RESULTS

Compared with nonusers of seizure detection devices, device users were significantly more likely to have been impacted by epilepsy in multiple HR-QOL domains, including anxiety, mood, emotional regulation/aggression, speech/language, sleep quality, social life, activities of daily living, independence, and education/academic potential. The majority (80.2%) of people using seizure detection devices experienced moderate or greater anxiety reduction from seizure detection device usage, while 11.1% reported that detection devices did not help at all with anxiety. Despite potential benefit, seizure detection devices were used only by a minority (21.8%) of people with epilepsy surveyed, and usage tended to be skewed toward younger patient age, higher income, and caregivers. There was no significant difference in overall HR-QOL between users and nonusers.

CONCLUSIONS

Seizure detection devices provide moderate or greater anxiety reduction among the majority of people with epilepsy and their caregivers, but current translatability into improvements in overall HR-QOL may be limited. Affordability and technological support are potential barriers to maximizing benefit equally among the epilepsy community. These considerations may be useful to help guide future device development and inform patient-clinician discussions on device usage and HR-QOL.

Safety and tolerability of adjunctive brivaracetam in children with focal seizures: Interim analysis of pooled data from two open-label trials

OBJECTIVE

To evaluate long-term safety and tolerability of adjunctive brivaracetam (BRV) in children with epilepsy.

METHODS

This was an interim analysis (cut-off March 15, 2017) of pooled data from two open-label, single-arm, multicentre trials. N01263 (NCT00422422) was a 3-week trial of BRV 0.8-4 mg/kg/day in patients (1 month-<16 years) with epilepsy. Patients who completed this trial could continue into a long-term follow-up trial (N01266, NCT01364597) which also directly enrolled patients (4-<17 years) with focal seizures. After dose-escalation, patients received BRV 1-5 mg/kg/day (maximum 200 mg/day) during long-term evaluation. Data are reported for patients aged 4 to <16 years with focal seizures.

RESULTS

The safety set comprised 149 patients: 34 from the initial trial (26 entered long-term trial) and 115 directly enrolled into the long-term trial. At the cut-off, 90 patients were receiving BRV (total exposure: 299.4 patient-years). Treatment-emergent adverse events (TEAEs) were reported by 140/149 (94.0%) patients, most commonly (≥20%) nasopharyngitis (24.8%), pharyngitis (22.1%), convulsion (21.5%), and pyrexia (20.1%). TEAEs considered drug-related by the investigator were reported by 56/149 (37.6%) patients, most commonly somnolence (6.0%). Two patients died; neither death was considered related to BRV. Mean changes from baseline in child behaviour rating scales were small; most patients remained in their baseline category.

CONCLUSION

In this pooled analysis of two open-label trials including long-term data, adjunctive BRV was generally well tolerated in children aged 4 to <16 years with focal seizures. These findings supported approval of BRV as a new therapy option for children aged ≥4 years with focal seizures.
