Study Overview
The investigation focused on developing a patient-reported outcome measure specifically designed to evaluate the severity of functional and dissociative seizures. These types of seizures, while resembling epileptic seizures clinically, are characterized by their dissociative nature and may have psychological rather than neurological underpinnings. Despite their significant impact on patients’ quality of life, these seizures often go underrecognized and misdiagnosed, leading to inadequate treatment and poor management strategies.
The study employed the e-Delphi technique, a structured communication method that utilizes a panel of experts to reach a consensus on critical issues. This approach was selected to gather insights and expert opinion efficiently while minimizing biases that might arise from face-to-face interactions. The e-Delphi method allows for multiple rounds of input, facilitating iterative refinement of ideas and fostering a comprehensive understanding of the factors essential for devising a robust outcome measure.
Participants included neurologists, psychologists, and other healthcare professionals with extensive experience in treating patients with functional and dissociative seizures, alongside patient advocates. The diverse expertise of the panel was essential in ensuring that the resulting outcome measure would be clinically relevant and applicable in real-world scenarios.
The aim was to culminate in a patient-centered instrument that would not only quantify seizure severity but also encapsulate the subjective experiences of those affected. By involving patients in the development process, the initiative sought to align the outcome measure more closely with their lived experiences and preferences regarding treatment and management options.
Through the integration of both expert opinion and patient perspective, the study aspired to address the gaps in existing measurement tools and ultimately contribute to improved clinical assessments and patient care in this complex area of neurology.
Methodology
The methodological framework of this study was anchored in the e-Delphi technique, which is recognized for its structured approach to gathering consensus among a panel of experts. This framework is particularly valuable in health research, where subjective experiences and professional insights significantly shape the understanding of complex clinical conditions. Central to this methodology was the careful selection of panelists, ensuring a diverse representation with both clinical expertise and lived experience related to functional and dissociative seizures.
To initiate the process, the research team identified key themes and areas for inquiry based on a comprehensive literature review and preliminary qualitative interviews with patients and healthcare professionals. This preliminary research helped to frame the questions that would shape the e-Delphi rounds. The e-Delphi process involved multiple rounds of questionnaires that allowed experts to reflect on and revise their responses, thus minimizing biases that could emerge from group dynamics inherent in traditional face-to-face meetings.
Participants were recruited through professional networks and clinical associations, targeting neurologists, psychologists, and other relevant healthcare providers, alongside patient advocates who could offer insights into the patient experience. A total of 30 expert panelists were successfully recruited, contributing a wealth of knowledge and differing perspectives. Each panelist was anonymized to promote candid discussions, with the aim of ensuring that all voices were equally heard without the influence of hierarchical dynamics.
The development of the patient-reported outcome measure was structured as follows:
1. **Round One Questionnaire**: The first round focused on broad themes related to the experience and impact of functional and dissociative seizures. Panelists provided their insights through open-ended questions, which allowed for the exploration of diverse opinions and the identification of key domains relevant to seizure severity.
2. **Synthesis and Iteration**: After the initial round, qualitative data were collated and analyzed to derive common themes and significant factors mentioned by the experts. This synthesis informed the development of specific questions and items that would be included in subsequent rounds.
3. **Round Two Questionnaire**: In the second round, panelists reviewed the synthesized themes and were asked to rate the importance of each item on a Likert scale. This quantification enabled the research team to identify consensus areas and divergent opinions among experts.
4. **Final Round**: A third round was held to refine the items further based on the feedback from the second round. Panelists were presented with the most highly rated items and invited to suggest modifications or additions. This iterative process ensured that the final measure was not only statistically valid but also resonated with the clinical realities faced by experts in the field.
Throughout this process, special emphasis was placed on the patient perspective. A subset of panelists included individuals who have experienced functional and dissociative seizures, ensuring that their views were integrated into developing the measure. Their contributions were invaluable in highlighting issues that may not have been adequately considered by the clinician-focused panels.
Data collected across the e-Delphi rounds were analyzed using descriptive statistics to identify consensus and variation among responses. Ethical considerations were paramount, and informed consent was obtained from all participants, with assurances that individual responses would be confidential.
In summary, this rigorous and structured methodology, grounded in expert collaboration and patient involvement, aimed to produce a valid and reliable tool that reflects both objective severity and subjective experiences related to functional and dissociative seizures. The outcome measure stands to bridge significant gaps in current assessments, potentially transforming patient care in this understudied area of neurology.
Results and Discussion
The e-Delphi process culminated in the development of a comprehensive patient-reported outcome measure (PROM) that captures the multifaceted nature of functional and dissociative seizures. The final instrument integrates varied dimensions of seizure experiences, emphasizing not only the quantifiable aspects of seizure severity but also the subjective nuances as reported by patients and their caregivers. This dual approach enhances both the clinical utility of the measure and its relevance to those impacted by these complex conditions.
In the first round of the e-Delphi process, panelists identified a broad range of factors influencing the severity of functional and dissociative seizures. Key themes emerged, including the frequency and duration of seizures, the contextual triggers, and the emotional and psychological impact on the patients involved. The qualitative responses highlighted a consensus on the importance of measuring not just the physiologic occurrences of seizures but also their implications on daily functioning, emotional wellbeing, and overall quality of life.
The synthesis of feedback from the first round informed the development of structured items for subsequent surveys. By the second round, panelists rated the significance of identified factors, revealing both consensus and areas of divergence. Notably, many panelists emphasized the role of psychological factors, such as anxiety or stress, in exacerbating seizure experiences. This pointed to the need for integrating questions that assess these psychological dimensions into the final measure. In contrast, some debates arose around the interpretation of seizure types and their delineation; however, through careful facilitation, a consensus was reached that incorporated the diverse experiences of both patients and clinicians.
The final round focused on refining the instrument further, validating that the items resonated well with both expert clinical opinions and patient experiences. A striking outcome was the inclusion of qualitative feedback from patients who participated as panelists. Their insights were pivotal in shaping nuances within the severity measures, and they underscored the variability in how seizures could affect individuals differently. This necessitated creating a flexible survey framework that accounts for individual patient variations, ensuring the measure is adaptable to various clinical presentations.
Statistical analysis of the data collected across the e-Delphi rounds showed robust agreement on core items, with high levels of consensus on several key measures of severity, emotional distress, and functional impairment. For example, consensus was achieved around key indicators such as the impact of seizures on daily activities, emotional health, and the presence of stigma or misunderstanding from others regarding the condition. These insights will be instrumental in guiding clinical assessments and facilitating better tailored treatment plans.
Moreover, the iterative feedback loops established by the e-Delphi process proved essential in enhancing the relevance and applicability of the measure. By allowing experts and patients to adjust their perspectives over multiple rounds, the final instrument benefits from a comprehensive and well-rounded design that reflects both scientific rigor and practical concerns encountered in clinical settings.
The resultant PROM is not merely a tool for quantifying seizure severity but a reflection of the collaborative endeavor to incorporate lived experiences into clinical assessment. It addresses significant gaps in the previous measures, which often failed to account for the subjective dimensions of the patient experience. Ultimately, this development will better support clinicians in diagnosing and managing functional and dissociative seizures, thereby improving patient outcomes and enhancing their quality of life.
The insights gained through this robust consensus-building process will pave the way for future studies aimed at validating the PROM in broader populations, exploring its application across different clinical settings, and its potential role in research contexts. By emphasizing a patient-centered approach, the study encourages ongoing dialogue within the medical community on the necessity of incorporating patient voices in health outcome measurements. These efforts to ground clinical tools in the real-life experiences of patients will be essential in creating more effective and personalized care strategies moving forward.
