Development of a Prospective Real-World Data Clinical Registry of Children and Adolescents With Migraine

The World Health Organization Intersectoral Global Action Plan on Epilepsy and Other Neurological Disorders and the headache revolution: from headache burden to a global action plan for headache disorders

The World Health Organization (WHO) Intersectoral Global Action Plan on Epilepsy and Other Neurological Disorders was developed by WHO to address the worldwide challenges and gaps in provision of care and services for people with epilepsy and other neurological disorders and to ensure a comprehensive, coordinated response across sectors to the burden of neurologic diseases and to promote brain health across life-course. Headache disorders constitute the second most burdensome of all neurological diseases after stroke, but the first if young and midlife adults are taken into account. Despite the availability of a range of treatments, disability associated with headache disorders, and with migraine, remains very high. In addition, there are inequalities between high-income and low and middle income countries in access to medical care. In line with several brain health initiatives following the WHOiGAP resolution, herein we tailor the main pillars of the action plan to headache disorders: (1) raising policy prioritization and strengthen governance; (2) providing effective, timely and responsive diagnosis, treatment and care; (3) implementing strategies for promotion and prevention; (4) fostering research and innovation and strengthen information systems. Specific targets for future policy actions are proposed. The Global Action Plan triggered a revolution in neurology, not only by increasing public awareness of brain disorders and brain health but also by boosting the number of neurologists in training, raising research funding and making neurology a public health priority for policy makers. Reducing the burden of headache disorders will not only improve the quality of life and wellbeing of people with headache but also reduce the burden of neurological disorders increasing global brain health and, thus, global population health.

More Than a Headache: Lived Experience of Migraine in Youth

BACKGROUND

Migraine is the leading cause of disability among adolescents and young adults. We aimed to characterize the impact of migraine on the experience of children, adolescents, and caregivers.

METHODS

This descriptive qualitative study recruited youth aged four to 18 years with migraine and their caregivers from the multicenter, prospective Pediatric Migraine Registry between 2020 and 2021. Participants completed semistructured interviews targeting the lived experience of migraine. A conventional content analysis approach was used to analyze data.

RESULTS

Thirty enrolled dyads (n = 30 children and adolescents, n = 29 caregivers) completed 59 interviews (n = 29 child and adolescent interviews, n = 30 caregiver interviews). Children and adolescents had a median age of 15 years and experienced a median of 13.5 headache days per month. Caregivers had a median age of 44 years and predominantly identified as mothers (n = 28). We identified three themes: (1) Impact on emotional well-being: participants described how their migraine experience included feelings of isolation, depression, and irritability alongside the need for social support; (2) Impact on daily life: participants described how symptoms and unpredictability impacted their ability to perform activities of daily living; and (3) Impact on school: participants described how migraine impacted their school experience, including threatened attendance and worsened performance.

CONCLUSIONS

In this cohort of youth and their caregivers, we identified salient themes to characterize the experience of migraine. Our findings underscore the urgent need for effective migraine treatments and interventions targeting co-occurring mental health conditions, peer relationships, and school support.

Brazilian headache registry: methods and preliminary data of the pilot study

BACKGROUND

Evaluation and treatment of primary and secondary headaches is a global public health challenge. Recognizing the epidemiological impact of headaches, a group of researchers linked to the Brazilian Headache Society proposed the Brazilian Headache Registry and drew up its initial protocol.

OBJECTIVE

Here we describe the methods and preliminary data obtained from the pilot study.

METHODS

This was a multicenter longitudinal observational study conducted between September 2020 and August 2021. Prospective data were collected in three specialist centers for headache care in states in southern and southeastern Brazil. Patients aged 18 years or older who sought care for headache in tertiary centers and who agreed to participate in the study, were considered eligible.

RESULTS

Sixty-six patients were included in the pilot study: 43 (65%) from Rio Grande do Sul state and 23 (35%) from Minas Gerais state. Overall, 90% were female, and the subjects' mean age was 38.2 ± 11.2 years. Primary headaches accounted for 85.3% of the diagnoses made. Among secondary headaches, medication overuse headache was the most frequent type (7.1%).

CONCLUSIONS

The pilot study showed the feasibility of the research protocol developed for tertiary centers. The Brazilian Headache Registry will form a source of longitudinal data with the aim of contributing to better characterization of the various phenotypes of patients with primary and secondary headaches, and to detailing the use of health resources and identifying predictors of better clinical outcomes.

Outpatient Approach to Resistant and Refractory Migraine in Children and Adolescents: a Narrative Review

PURPOSE OF REVIEW

Migraine is one of the top reasons for consulting a pediatric neurologist. Although the majority of children and adolescents who receive evidence-based first-line interventions for migraine will improve substantially, a subset of patients develop resistant or refractory migraine.

RECENT FINDINGS

In this review, we summarize the level of evidence for a variety of acute and preventive treatment options to consider in children and adolescents with resistant or refractory migraine. We describe the level of evidence for interventional procedures (onabotulinumtoxinA injections, greater occipital and other nerve blocks), neuromodulation (single-pulse transcranial magnetic stimulation, external trigeminal nerve stimulation, remote electrical neuromodulation, and non-invasive vagal nerve stimulation), calcitonin gene-related peptide (CGRP) pathway antagonists (anti-CGRP monoclonal antibodies and gepants), psychological therapies, and manual therapies (acupuncture, craniosacral therapy, massage and physical therapy, and spinal manipulation).

The headache registry of the German Migraine and Headache Society (DMKG): baseline data of the first 1,351 patients

Background

Although good treatment options exist for many headache disorders, not all patients benefit and disability continues to be large. To design strategies for improving headache care, real-world data observing standard care is necessary. Therefore, the German Migraine and Headache Society (DMKG) has established the DMKG Headache Registry. Here we present methods and baseline data.

Methods

Accredited German headache centers (clinic-based or private practice) can offer participation to their patients. Patients provide headache history, current headache load (including a mobile headache diary), medication and comorbidities and answer validated questionnaires, prior to their physician appointment. Physicians use these data as the base of their history taking, and add, change or confirm some central information. Before the next visit, patients are asked to update their data. Patients will continuously be included over the next years.

Results

The present analysis is based on the first 1,351 patients (1110 females, 39.6 ± 12.9 years) with a completed first visit. Most participants had a migraine diagnosis. Participants had 14.4 ± 8.5 headache days and 7.7 ± 6.1 acute medication days per month and 63.9% had a migraine disability assessment (MIDAS) grade 4 (severe disability). 93.6% used at least one acute headache medication, most frequently a triptan (60.0%) or non-opioid analgesic (58.3%). 45.0% used at least one headache preventive medication, most frequently an antidepressant (11.4%, mostly amitriptyline 8.4%) or a CGRP(receptor) antibody (9.8%). Most common causes for discontinuation of preventive medication were lack of effect (54.2%) and side effects (43.3%).

Conclusion

The DMKG Headache Registry allows to continuously monitor headache care at German headache centers in both a cross-sectional and a longitudinal approach.

Trial registration

The DMKG Headache Registry is registered with the German Clinical Trials Register (DRKS 00021081).

Beyond pain control: Outcome and treatment preferences in pediatric migraine

OBJECTIVE

The objective of this study was to describe treatment preferences and perceived quality of existing outcome measures among children and adolescents with migraine and their caregivers.

BACKGROUND

Across disciplines, there is increasing recognition of the value of direct input from stakeholders. Little empirical work has been done to determine what outcomes matter most to pediatric patients with migraine and their caregivers.

METHODS

In this qualitative study, we recruited participants from the multicenter, prospective Pediatric Migraine Registry. We used stratified purposive sampling to recruit children and adolescents of varied ages and headache frequency. Patients with migraine and their caregivers completed semistructured interviews targeting treatment preferences and perceived quality of existing outcome measures. Emergent themes and subthemes were identified using conventional content analysis.

RESULTS

Thirty dyads of children/adolescents and their caregivers were enrolled and completed 59 interviews (n = 29 children/adolescent interviews and n = 30 caregiver interviews). Three themes emerged. (1) Symptom relief: Looking beyond headache resolution: Participants described the value of outcomes in addition to pain relief, including a reduction in migraine intensity and improvement in non-pain symptoms. (2) Trade-offs between side effects and relief: Participants described cost-benefit analyses that can occur with headache treatment and acknowledged the impact of drug side effects on daily life and medication adherence. (3) Child-centered treatment: Participants described medication attributes salient to the pediatric context, including age-appropriate routes of administration and adequate safety data.

CONCLUSIONS

Children, adolescents, and caregivers impacted by migraine value outcomes in addition to traditionally studied migraine endpoints. Participants valued decreased pain severity, even in the absence of pain resolution. Participants also prioritized the absence of side effects and key medication attributes, including fast onset and age-appropriate routes of administration. These results highlight an opportunity to design patient-centered clinical trials, develop drugs, and support product labeling that align with the outcomes valued most by children and adolescents with migraine and their caregivers.

Contemporary use of real-world data for clinical trial conduct in the United States: a scoping review

OBJECTIVE

Real-world data (RWD), defined as routinely collected healthcare data, can be a potential catalyst for addressing challenges faced in clinical trials. We performed a scoping review of database-specific RWD applications within clinical trial contexts, synthesizing prominent uses and themes.

MATERIALS AND METHODS

Querying 3 biomedical literature databases, research articles using electronic health records, administrative claims databases, or clinical registries either within a clinical trial or in tandem with methodology related to clinical trials were included. Articles were required to use at least 1 US RWD source. All abstract screening, full-text screening, and data extraction was performed by 1 reviewer. Two reviewers independently verified all decisions.

RESULTS

Of 2020 screened articles, 89 qualified: 59 articles used electronic health records, 29 used administrative claims, and 26 used registries. Our synthesis was driven by the general life cycle of a clinical trial, culminating into 3 major themes: trial process tasks (51 articles); dissemination strategies (6); and generalizability assessments (34). Despite a diverse set of diseases studied, <10% of trials using RWD for trial process tasks evaluated medications or procedures (5/51). All articles highlighted data-related challenges, such as missing values.

DISCUSSION

Database-specific RWD have been occasionally leveraged for various clinical trial tasks. We observed underuse of RWD within conducted medication or procedure trials, though it is subject to the confounder of implicit report of RWD use.

CONCLUSION

Enhanced incorporation of RWD should be further explored for medication or procedure trials, including better understanding of how to handle related data quality issues to facilitate RWD use.

Design and development of a web-based registry for Coronavirus (COVID-19) disease

Background: The 2019 coronavirus (COVID-19) is a highly contagious disease associated with a high morbidity and mortality worldwide. The accumulation of data through a prospective clinical registry enables public health authorities to make informed decisions based on real evidence obtained from surveillance of COVID-19. This registry is also fundamental to providing robust infrastructure for future research surveys. The purpose of this study was to design a registry and its minimum data set (MDS), as a valid and reliable data source for reporting and benchmarking COVID-19. Methods: This cross sectional and descriptive study provides a template for the required MDS to be included in COVID-19 registry. This was done by an extensive literature review and 2 round Delphi survey to validate the content, which resulted in a web-based registry created by Visual Studio 2019 and a database designed by Structured Query Language (SQL). Results: The MDS of COVID-19 registry was categorized into the administrative part with 3 sections, including 30 data elements, and the clinical part with 4 sections, including 26 data elements. Furthermore, a web-based registry with modular and layered architecture was designed based on final data classes and elements. Conclusion: To the best of our knowledge, COVID-19 registry is the first designed instrument from information management perspectives in Iran and can become a homogenous and reliable infrastructure for collecting data on COVID-19. We hope this approach will facilitate epidemiological surveys and support policymakers to better plan for monitoring patients with COVID-19.
