Our Methodology and Evidence Standards

Core Principle: Following Clinical Standards, Not Setting Them

Migriscope does not conduct original medical research, develop novel diagnostic criteria, or create treatment guidelines. Our role is to translate existing clinical standards into accessible patient-facing tools.

We build upon:

• Published diagnostic criteria from recognized medical bodies
• Evidence-based clinical practice guidelines
• Validated patient-reported outcome measures
• Standard documentation practices used in neurology and headache medicine

Our methodology prioritizes alignment with mainstream clinical consensus over emerging or controversial approaches.

Information Selection Process

Source Identification

We focus on high-quality sources with established authority in headache medicine:

Primary sources:

• International Headache Society (IHS) and the International Classification of Headache Disorders, Third Edition (ICHD-3)
• American Headache Society (AHS) evidence-based guidelines
• American Academy of Neurology (AAN) practice parameters and systematic reviews
• National Institute of Neurological Disorders and Stroke (NINDS)
• European Headache Federation (EHF) guidelines
• Peer-reviewed medical literature from established neurology and headache journals

Secondary sources:

• Medical textbooks on headache and neurology from academic publishers
• Systematic reviews and meta-analyses from Cochrane and similar evidence synthesis groups
• Clinical policy statements from specialty societies
• FDA labeling and approval documents for migraine treatments

Excluded sources:

• Anecdotal reports or personal testimonials
• Non-peer-reviewed publications
• Sources with significant commercial conflicts of interest
• Blogs, social media, or unvetted user-generated content
• Preliminary research not yet confirmed by broader evidence

Content Development

Our question sets and educational materials undergo systematic development:

1. Literature review: We identify relevant clinical guidelines and diagnostic criteria for the specific topic
2. Clinical consensus identification: We prioritize recommendations with strong evidence and broad expert agreement
3. Translation to patient-facing language: We convert clinical terminology to accessible language while preserving medical accuracy
4. Relevant information extraction: We include elements neurologists routinely assess during clinical encounters
5. Structured organization: We organize information following standard clinical documentation patterns

Review and Updates

Medical knowledge evolves. Our methodology includes:

• Periodic content review: We review educational content and question sets at least annually
• Guideline updates: When major organizations publish updated guidelines, we assess implications for our content
• User feedback: We consider input from patients and clinicians about unclear or missing information
• Error correction: We promptly address identified errors in medical content

Types of Evidence We Reference

Clinical Practice Guidelines

Clinical practice guidelines synthesize research evidence and expert consensus into actionable recommendations for clinical care. We prioritize:

Grade A/Level 1 recommendations: Those supported by high-quality randomized controlled trials and strong evidence

Consensus-based guidelines from major organizations: Particularly from the American Headache Society, American Academy of Neurology, and European Federation of Neurological Societies

Guidelines inform our understanding of:

• When specialist referral is appropriate
• What information neurologists need for diagnosis
• Standard treatment approaches and sequences
• Documentation requirements for insurance authorization

Diagnostic Criteria

Migraine diagnosis relies on criteria published by the International Headache Society. The current standard is ICHD-3, released in 2018.

We reference these criteria to:

• Ensure our questions cover diagnostic features neurologists assess
• Clearly distinguish chronic migraine (15+ headache days/month) from episodic migraine
• Align terminology with clinical standards
• Explain diagnostic concepts to patients

We do not apply these criteria to diagnose users. Only qualified healthcare providers can diagnose headache disorders.

Peer-Reviewed Research

We reference published research studies to:

• Understand headache epidemiology and disease burden
• Explain pathophysiology in accessible terms
• Describe validated outcome measures
• Provide context for clinical recommendations

We prioritize:

• Systematic reviews and meta-analyses over single studies
• Studies published in high-impact, peer-reviewed journals
• Research with appropriate methodology and statistical rigor
• Findings replicated across multiple studies

We avoid citing:

• Preliminary or contradictory single studies
• Research not yet confirmed by broader evidence
• Studies with significant methodological limitations
• Industry-sponsored research as sole support for claims

Validated Assessment Tools

We incorporate established patient-reported outcome measures:

MIDAS (Migraine Disability Assessment Scale):

• Developed by Stewart and colleagues, published 1999
• Validated across multiple populations
• Measures lost time due to migraine across work, household, and social domains
• Widely used in clinical practice and research
• Categorizes disability as Grade I (minimal) through Grade IV (severe)

HIT-6 (Headache Impact Test):

• Developed as part of the Headache Impact Assessment project
• 6-item questionnaire assessing headache impact on daily life
• Scores range from 36 to 78, with higher scores indicating greater impact
• Validated for monitoring treatment response
• Commonly used for insurance documentation

These tools provide standardized metrics neurologists recognize and value.

Professional Organization Resources

We reference educational materials from:

• American Migraine Foundation (patient education developed by headache specialists)
• National Headache Foundation
• Migraine Research Foundation
• American Headache Society patient resources

These organizations translate clinical evidence into patient-friendly information, serving as models for accessible medical communication.

How Our Summaries Align with Clinical Documentation

Migriscope's generated summaries are structured to match documentation patterns neurologists use in clinical practice.

Standard Documentation Elements

Neurology notes typically include:

Chief complaint: The primary problem prompting consultation

History of present illness: Detailed chronological description of symptoms, including:

• Headache frequency and pattern
• Attack characteristics (onset, duration, location, quality, severity)
• Associated symptoms
• Triggers and relieving factors
• Impact on function

Medication history:

• Current medications with doses
• Prior trials with outcomes
• Allergies and intolerances

Past medical history: Relevant conditions and surgical history

Social history: Occupation, stress, substance use

Review of systems: Systematic symptom review

Physical examination: Neurological and general exam findings

Assessment: Clinical impression and differential diagnosis

Plan: Diagnostic workup and treatment recommendations

Migriscope's summary format mirrors the "History of Present Illness" and "Medication History" components—the sections that:

• Consume the most appointment time to gather verbally
• Are most prone to patient recall errors
• Provide the foundation for clinical reasoning

Organization Principles

Our summaries follow these documentation principles:

Structured data presentation: Information organized in standardized categories rather than narrative paragraphs

Quantitative metrics: Specific numbers (days per month, severity scores) rather than vague descriptors

Chronological consistency: Medication trials presented in order with dates when available

Completeness: All major clinical dimensions addressed systematically

Conciseness: One-page format requiring minimal reading time

Professional language: Medical terminology used appropriately while remaining patient-readable

This alignment serves two purposes:

1. Neurologists can quickly locate relevant information in familiar format
2. Documentation can support insurance authorization requiring similar data

Validated Tools: MIDAS and HIT-6

Migriscope incorporates two widely-accepted disability measures used in both clinical practice and insurance documentation.

MIDAS (Migraine Disability Assessment Scale)

Purpose: Quantifies migraine-related disability over a 3-month period

Structure: 5 questions assessing:

• Days of missed work or school
• Days of reduced productivity at work or school
• Days of missed household work
• Days of reduced productivity in household work
• Days of missed family, social, or leisure activities

Scoring:

• Grade I (0-5): Minimal disability
• Grade II (6-10): Mild disability
• Grade III (11-20): Moderate disability
• Grade IV (21+): Severe disability

Clinical use:

• Helps identify candidates for preventive treatment
• Tracks treatment response
• Supports insurance authorization for preventive medications
• Provides objective functional impact metric

Evidence base: Validated across multiple studies, demonstrates reliability and correlation with headache-related disability

HIT-6 (Headache Impact Test)

Purpose: Assesses the impact of headaches on ability to function

Structure: 6 questions evaluating:

• Pain severity
• Impact on daily activities
• Wish to lie down
• Feeling fed up or irritated
• Difficulty concentrating
• Impact on work, school, or daily activities

Scoring:

• 36-49: Little to no impact
• 50-55: Some impact
• 56-59: Substantial impact
• 60-78: Very severe impact

Clinical use:

• Complements frequency data with quality-of-life assessment
• Monitors treatment effectiveness
• Identifies functional impairment beyond headache days
• Supports disability and insurance documentation

Evidence base: Psychometrically validated, responsive to treatment changes, widely accepted in headache research and practice

Migriscope includes these tools because they:

• Provide standardized metrics recognized by clinicians
• Offer quantitative data supporting treatment decisions
• Align with insurance documentation requirements
• Are brief and patient-friendly

Update Policy

Medical knowledge evolves through ongoing research and clinical experience. Migriscope maintains currency through:

Regular Content Review

We conduct systematic content audits at least annually, assessing:

• Accuracy of medical information
• Alignment with current guidelines
• Completeness of clinical question sets
• Clarity of patient-facing language

Guideline Tracking

We monitor publications from key organizations:

• International Headache Society (ICHD updates)
• American Headache Society (revised guidelines)
• American Academy of Neurology (new practice parameters)
• FDA (new drug approvals or safety alerts relevant to migraine)

When major guidelines are updated, we:

1. Review the changes and implications for our content
2. Assess necessary updates to question sets or educational materials
3. Implement changes within 3-6 months of guideline publication
4. Note the update date on affected pages

Error Correction

If we identify factual errors, outdated information, or misleading content, we:

• Correct the issue promptly (within days for significant errors)
• Review related content for similar issues
• Document the change internally
• Consider process improvements to prevent recurrence

User Feedback Integration

We welcome input from patients and healthcare providers about:

• Unclear or confusing content
• Missing information relevant to clinical appointments
• Technical issues affecting usability
• Suggestions for improvement

Feedback informs our ongoing content development, though we evaluate suggestions against our evidence standards before implementation.

Non-Diagnostic Disclaimer

Migriscope does not diagnose medical conditions.

This limitation is fundamental and intentional. Migraine diagnosis requires:

• Pattern recognition across multiple dimensions: No single feature confirms migraine; diagnosis requires integrating frequency, duration, pain characteristics, associated symptoms, and medical history
• Exclusion of secondary causes: Headaches can result from serious conditions requiring different management; neurologists assess for "red flags" warranting additional workup
• Physical examination: Neurological examination identifies signs not captured by patient history
• Clinical judgment: Experienced clinicians recognize atypical presentations, assess differential diagnoses, and weigh probabilistic reasoning

Migriscope collects information but does not interpret it clinically. We:

• Do not apply diagnostic algorithms
• Do not provide diagnostic conclusions based on user responses
• Do not rule out serious conditions
• Do not substitute for comprehensive medical evaluation

Users experiencing headaches should seek evaluation by qualified healthcare providers regardless of their Migriscope responses.

Transparency: What Migriscope Does Not Claim

In the interest of transparency, we explicitly state what Migriscope does not do:

We Do Not Provide Medical Advice

Migriscope does not:

• Recommend specific treatments or medications
• Advise on treatment changes or medication adjustments
• Suggest when to seek emergency care (always err toward seeking care if concerned)
• Interpret your symptoms or clinical situation
• Replace consultation with healthcare providers

We Do Not Conduct Clinical Validation Studies

While our question set is based on standard clinical assessments:

• We have not validated Migriscope as a diagnostic tool
• We have not conducted clinical trials demonstrating improved outcomes
• We make no claims about diagnostic accuracy or treatment effectiveness
• We do not assert that using Migriscope improves health outcomes (though we believe better preparation supports productive appointments)

We Do Not Analyze User Data for Clinical Insights

Migriscope:

• Organizes information users provide in a structured format
• Does not apply machine learning or AI to interpret symptoms
• Does not compare user responses to population data
• Does not generate personalized health insights or predictions

We Do Not Replace Healthcare Relationships

Migriscope:

• Supports—but never substitutes—for medical appointments
• Does not provide ongoing clinical management
• Does not monitor treatment safety or effectiveness
• Does not serve as a telemedicine or direct-to-consumer care platform

We Do Not Guarantee Insurance Approval

While our summaries include information often required for prior authorization:

• Insurance coverage decisions are made by payers using their own criteria
• We cannot ensure any particular treatment will be approved
• We do not advocate with insurance companies on users' behalf
• We do not guarantee that our documentation meets all payer requirements

Methodological Limitations

Our methodology has inherent limitations users should understand:

Limited scope: We focus specifically on migraine preparation; our framework may not fully apply to other headache types or neurological conditions

Evidence lag: Clinical guidelines take time to develop after new research emerges; our content reflects established consensus, not cutting-edge findings

Generalization: Clinical practice varies across providers and settings; our framework reflects common patterns but cannot capture all practice variations

Patient recall: Our summaries depend on user-provided information, which may be incomplete, inaccurate, or subject to recall bias

Simplification: Translating complex clinical concepts to accessible language inevitably involves simplification that may lose nuance

Access limitations: Our tool does not solve systemic healthcare access problems (appointment availability, insurance coverage, specialist shortages)

We encourage users to view Migriscope as one resource among many, used in conjunction with qualified professional care.

Our Commitment to Evidence-Based Standards

Migriscope is built on the principle that patient tools should align with established medical evidence and clinical practice. We commit to:

• Grounding content in recognized clinical standards
• Citing authoritative sources
• Updating information as evidence evolves
• Being transparent about limitations
• Avoiding unsupported claims
• Prioritizing patient safety through appropriate disclaimers and guidance

We welcome ongoing dialogue with patients and healthcare providers about how to best support effective clinical preparation within appropriate ethical and medical boundaries.
