Clinical Trial Participant Portal UX Brief
Design a high-retention, accessible participant portal brief for decentralized clinical trials.
Use this template when scoping user onboarding, e-consent, and recurring diary entry experiences for clinical trial participants. It ensures medical literacy, regulatory adherence, and participant engagement are addressed upfront.
Role: Senior Healthcare Interaction Designer specializing in decentralized clinical trial participant experience.
Context
- Trial Sponsor: {{sponsor_name}}
- Therapeutic Area: {{therapeutic_area}}
- Target Cohort Demographics & Literacy: {{patient_cohort_profile}}
- Regulatory & Accessibility Standard: {{compliance_standard}}
- Primary User Devices: {{primary_digital_touchpoints}}
- Protocol Telemetry Frequency: {{data_collection_frequency}}
Task
Produce an actionable UI/UX design brief that outlines information architecture, cognitive load mitigations, and accessibility-first interaction patterns for trial participants using the digital portal.
Method
- Synthesize {{patient_cohort_profile}} physical and cognitive constraints against {{therapeutic_area}} symptoms.
- Map the digital e-consent and daily logging journey across {{primary_digital_touchpoints}}.
- Identify high-friction drop-off points during {{data_collection_frequency}} data entry events.
- Define inclusive UI patterns ensuring compliance with {{compliance_standard}} across varied vision and motor abilities.
- Structure clear progressive disclosure rules for complex medical trial disclosures and protocol instructions.
- Formulate micro-interaction criteria that validate data integrity without inducing participant anxiety.
- Establish UX feedback loops for incomplete or delayed diary entries under {{sponsor_name}} oversight.
Constraints
- MUST adhere to {{compliance_standard}} accessibility contrast and text-scaling mandates.
- MUST NOT introduce medical jargon above a 6th-grade reading level in participant-facing UI strings.
- All critical logging tasks must be completable within 3 taps or keystrokes from the dashboard.
- Provide clear state-handling for low-bandwidth and offline data capture.
Output format
- Executive UX Summary (max 150 words)
- Participant Archetype & Friction Analysis (table with 3 friction vectors)
- Key Screen Specifications: Onboarding, Daily Logging, Compliance Hub (bulleted interaction rules)
- Accessibility & Tone Directives (5 explicit rules)
- Success Metrics & Usability Acceptance Criteria (4 measurable KPIs)
Self-review
- Does every interaction pattern accommodate the physical limitations noted in {{patient_cohort_profile}}?
- Are all {{primary_digital_touchpoints}} addressed with consistent UI ergonomics?
- Is the tone encouraging while preserving clinical neutral objectivity?
Explicit role, a named task, and discrete steps the model can follow.
Background, inputs and variables the model needs before it starts.
Hard boundaries — what the model must and must not do.
A named, field-level shape for the response.
Ordered work items that force analysis before an answer.
Length and structure that travel across frontier models.
Signal density — instruction weight without padding.
Documented variables so the scaffold adapts to new inputs.
Quality bar, assumptions and behaviour when inputs are thin.
How much real usage the template has behind it.
