Temporal trends in the cost and use of first-line treatments for infantile epileptic spasms syndrome. Epilepsia 2023; 64:630-640. [PMID: 36600453 DOI: 10.1111/epi.17498] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2022] [Revised: 12/19/2022] [Accepted: 01/03/2023] [Indexed: 01/06/2023]
Abstract
OBJECTIVE To describe the temporal trends in the cost and use of adrenocorticotropic hormone (ACTH), oral prednisolone, and vigabatrin, the first-line treatments for infantile epileptic spasms syndrome (IESS). METHODS Retrospective observational study using the MarketScan Commercial database from 2006 to 2020. We identified patients with IESS diagnosed between birth and 18 months of age who received at least one of the first-line treatments within 60 days of diagnosis. Costs were adjusted for inflation using the Gross Domestic Product Implicit Price Deflator. RESULTS A total of 1131 patients received at least one first-line treatment (median [p25 -p75 ] age: 6.3 [4.5-8.3] months, 55% male), of whom 592 patients received ACTH, 363 patients received oral prednisolone, and 355 patients received vigabatrin. After adjusting for inflation, the median average wholesale price of a 14-day course of treatment increased for ACTH from $3718 in 2006 to $100 457 in 2020, ~2700% (by a factor of 27), whereas it decreased for oral prednisolone from $169 in 2006 to $89 in 2020, ~50% (by a factor of 0.5), and increased for vigabatrin from $1206 in 2009 (first year with data on vigabatrin used for IESS) to $4102 in 2020, ~340% (by a factor of 3.4). During the first 60 days after diagnosis, inpatient admission days and costs where higher for ACTH than for oral prednisolone and vigabatrin-5.0 (3.0-8.3) days vs 2.0 (0.0-5.0) days vs 2.0 (0.0-6.0) days, p < .0001; and $32 828 ($14 711-$67 216) vs $16 227 ($0-$35 829) vs $17 844 ($0-$47 642), p < .0001. ACTH use decreased from representing 78% of first-line treatments in 2006 to 18% in 2020 (p < .0001). Sensitivity analyses confirmed the robustness of the results. SIGNIFICANCE The gap between the cost of ACTH and the cost of oral prednisolone or vigabatrin has widened markedly from 2006 to 2020, whereas the relative proportion of ACTH use has decreased.

GRIN2A-related epilepsy and speech disorders: A comprehensive overview with a focus on the role of precision therapeutics. Epilepsy Res 2023; 189:107065. [PMID: 36516565 DOI: 10.1016/j.eplepsyres.2022.107065] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2022] [Revised: 10/27/2022] [Accepted: 12/08/2022] [Indexed: 12/14/2022]
Abstract
Language dysfunction is a common and serious comorbidity of epilepsy, especially in individuals with epilepsy aphasia spectrum syndromes. Childhood epilepsy with centrotemporal spikes is on the mild end of the spectrum, while epileptic encephalopathy with continuous spike-and-wave during sleep syndrome is on the severe end. Traditional antiseizure medicines and immunotherapy are currently used to treat severely affected patients, but the results are usually disappointing. The discovery that GRIN2A is the primary monogenic etiology of these diseases has opened the door to precision treatments. The GRIN2A gene encodes GluN2A protein, which constitutes a subunit of the NMDA receptor (NMDAR). The GRIN2A pathogenic variants cause gain or loss of function of NMDAR; the former can be treated with uncompetitive NMDAR antagonists, such as memantine, while the latter with NMDAR co-agonist serine. Hyper-precision therapies with various other effective agents are likely to be developed shortly to target the diverse functional effects of different variants. Precision treatments for GRIN2A-related disorders will benefit those who suffer from the condition and pave the way for new therapeutic approaches to a variety of other NMDAR-linked neurodegenerative and psychiatric diseases (schizophrenia, Parkinson's disease, Alzheimer's disease, and so on). Furthermore, more research into GRIN2A-related disorders will help us better understand the neuroinflammatory and neuroimmunological basis of epilepsy, as well as the pathological and physiological network activation mechanisms that cause sleep activation of central-temporal spikes and language impairment.

The role of implementation science in improving epilepsy surgery utilization. Epilepsy Behav 2022; 130:108669. [PMID: 35334257 PMCID: PMC9064925 DOI: 10.1016/j.yebeh.2022.108669] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/20/2022] [Revised: 03/08/2022] [Accepted: 03/09/2022] [Indexed: 11/24/2022]
Abstract
Randomized controlled studies demonstrated that patients with intractable epilepsy could benefit significantly more from epilepsy surgery than from continuing medical therapy. Unfortunately, robust efforts over the last few decades, including the formation and dissemination of guidelines and practice parameters, did not improve the utilization of epilepsy surgery. Epilepsy surgery remains one of the most underutilized evidence-based interventions in modern medicine. A new scientific study of methods has emerged to improve uptake of evidence-based practices, named implementation science (IS). Despite its tremendous rise in popularity in various domains, its usage to mitigate epilepsy surgery underutilization is very limited. In fact, the application of principles and methods of IS are somewhat restricted in the entire neuroscience field, where quality improvement (QI) efforts primarily drive the provision of high-quality health care. Although both QI efforts and IS have a similar goal of improving healthcare quality, they differ significantly in associated terminologies, concepts, and approaches. For implementing high-quality, evidence-based practices in routine clinical settings, we need a better understanding of IS methods and closer integration between QI and IS fields. Recognizing a dearth of awareness of IS in the neuroscience community, the first part of the review addresses the fundamentals of IS, focusing on multifaceted implementation strategies that neurologists can apply in their clinical practice. In the second part of the review, an entire illustrative case is presented to familiarize neurologists with the practical application of diverse implementation strategies to mitigate the underutilization of epilepsy surgery.

Physicians' Perspectives on Presurgical Discussion and Shared Decision-Making in Pediatric Epilepsy Surgery. J Child Neurol 2022; 37:416-425.

Abstract
Objective: To qualitatively explore the approach of pediatric epilepsy providers when counseling regarding surgical options for epilepsy, presenting risks and benefits of surgery, overcoming resistance to surgery, and fostering shared decision making with patients and families. Methods: We conducted in-depth interviews with 11 academic clinicians (5- neurologists, 5- epileptologists, 1- neurosurgeon) from a Level 4 pediatric epilepsy center to explore how physicians communicate and pursue surgical decision-making. Results: A blended inductive-deductive analysis revealed three key themes (with subthemes) of presurgical discussions: (1) Candidate selection and initial discussion about epilepsy surgery (neurologists compared to epileptologists, the timing of the discussion, reluctant families) (2) Detailed individualized counseling about epilepsy surgery (shared decision-making [enablers and barriers] and risk-benefit analysis [balancing risks and benefits, statistical benefit estimation, discussion about SUDEP, prognostication about cognitive and behavioral outcomes, risks of surgery]) (3) Tools to improve decision-making (educational interventions for patients and families and provider- and organization-specific interventions). Significance: Presurgical discussions lack uniformity among physicians who treat epilepsy. Despite general interest in collaborative decision-making, experts raised concern about lack of exposure to communication training and clinical tools for optimizing decision-making, a high number of families who do not feel equipped to share the decision making leaving the decision-making entirely to the physician, and paucity of practical resources for individualized risk-benefit counseling. Clinical practice guidelines should be developed to reduce existing practice variations in presurgical counseling. Further consensus is needed about when and how to initiate the conversation about epilepsy surgery, essential components of the discussion, and the utility of various tools to improve the utilization of epilepsy surgery.

Abstract
OBJECTIVE The study aimed to identify the signatures of brain networks using electroencephalogram (EEG) in patients with infantile spasms (IS). METHODS Scalp EEGs of subjects with IS were prospectively collected in the first year of life (n = 8; age range 4-8 months; 3 males, 5 females). Ten minutes of ictal and interictal EEGs were clipped and filtered into different EEG frequency bands. The values of each pair of EEG channels were directly compared between ictal with interictal onsets and the sleep-wake phase to calculate IS brain network attributes: characteristic path length (CPL), node degree (ND), clustering coefficient (CC), and betweenness centrality (BC). RESULTS CPL, ND, and CC of the fast waves decreased while BC increased. CPL and BC of the slow waves decreased, while ND and CC increased during the IS ictal onset (P < 0.05). CPL of the alpha decreased, and BC increased during the waking time (P < 0.05). CONCLUSION The transmission capability of the fast waves, the local connectivity, and the defense capability of the slow waves during the IS ictal onset were enhanced. The alpha band played the most important role in both the global and local networks during the waking time. These may represent the brain network signatures of IS.

Abstract
OBJECTIVE To describe the rapid conceptualization and implementation of an interdisciplinary epilepsy clinic for children with drug-resistant epilepsy (DRE) at Arkansas Children's Hospital (ACH) during the COVID 19 pandemic. METHODS Focusing on care design and care coordination for children with DRE, multiple stakeholder groups decided to implement a clinic after the systematic rating of constructs present in a theoretical meta-analytic framework. Based on the projected success, the new interdisciplinary clinic (composed of an epileptologist, a neurosurgeon, and a neuropsychologist and coordinated by a full-time nurse) was established. Clinic operations were further refined through discussions with patients, families, and care providers. We collected data retrospectively (August 2020 to June 2021) to determine referral patterns, clinic scheduling metrics, patient characteristics, clinical recommendations, and epilepsy quality metrics. RESULTS Of the 32 Consolidated Framework for Implementation Research constructs assessed, 24 were positively rated to predict a high probability of successful implementation of the clinic. For approximately 100 patient visits, appearance and usage rates were >75%, yielding a clinic utilization rate of approximately 60%. Among 76 unique patients (average age of 12 years, 60% focal epilepsy), 39 patients (51.3%) were deemed eligible for epilepsy surgery evaluation. The majority of the patients (53.9%) were advised for additional diagnostic testing, and 31.6% of patients were scheduled for vagus nerve stimulation. More patients (33%) had changes in their existing anti-seizure medication (ASM) regimen rather than an addition of a new ASM (7.9%). Standardized epilepsy quality measures showed >80% to 90% adherence in 3 (reproductive counseling, depression and anxiety screening, documentation of seizure frequency) out of 4 metrics. SIGNIFICANCE This is the first study to show that an interdisciplinary clinic can be a valuable attribute of care models in high-need children with DRE by enabling comprehensive one-stop service for diagnostic evaluation, surgical consideration, and brief assessment of psychiatric comorbidities without compromising consensus-based best practices.

Abstract
Neurological disorders are the leading cause of disability and the second leading cause of death globally. To challenge this enormous disease burden, scientists are pursuing innovative solutions to maintain and improve the quality of neurological care. Despite the availability of many effective evidence-based practices, many patients with neurological disorders cannot access these (or receive them inefficiently after a long delay) and may be exposed to unnecessary, expensive, and potentially harmful treatments. To promote the systematic uptake of evidence-based practices into the real world, a new scientific study of methods has been developed: implementation science. In implementation science research, transdisciplinary research teams systematically (using theory, model, and framework) assess local barriers to facilitate the adoption of evidence-based practices and examine potential solutions using implementation strategies (interventions that help adoption of intended practices) targeting multiple levels in the health care system, including patient, provider, clinic, facility, organization, or broader community and policy environment. The success of these strategies (implementation outcomes) is measured by the extent and quality of the implementation. Implementation studies can be either observational or interventional but are distinct from traditional efficacy or effectiveness studies. Traditional neuroscience research and clinical trials, conducted in controlled settings, focus on discovering new insights with little consideration of translating those insights into the everyday practice of a resource-constrained and dynamic health care system. Thus, neurologists should become familiar with implementation science to reduce the knowledge-practice gap, maximize health care value, and improve management of brain disorders affecting public health.
