Functional Analysis

This section describes the functional use of electronic Product Information (ePI) within the Gravitate Health (GH) ecosystem.
It focuses on how ePI is discovered, accessed, interpreted, and personalized for different users to support safe, informed, and empowered medicine use.

Purpose

The Gravitate Health Functional Analysis examines how the ePI — a trusted, regulator-approved source of information about medicines — can be leveraged in daily practice by patients, healthcare professionals (HCPs), and caregivers.

Rather than introducing new content, Gravitate Health focuses on enhancing the usability and relevance of the existing ePI by tailoring it to the individual’s context and needs.

This is achieved through the Lens concept, which filters, emphasizes, and presents ePI information in a personalized and accessible way.

Functional Use of ePI

The ePI provides structured and standardized information about a medicine, such as:

  • Therapeutic indications
  • Dosage and administration instructions
  • Contraindications and precautions
  • Adverse reactions
  • Storage and disposal instructions

In traditional form, this information is static and identical for all users.
In the Gravitate Health framework, ePI becomes dynamic and user-centered, enabling tailored access and understanding.

The Lens Concept in Functional Context

The Lens acts as a functional layer between the user and the ePI.
It does not modify the original content but personalizes its presentation based on user-specific parameters and context.

Example functions

  • Filtering: Only show sections relevant to a user’s condition (e.g., pregnancy, diabetes).
  • Highlighting: Emphasize warnings, dosage details, or interactions pertinent to a user’s medications.
  • Simplifying: Present complex sections in plain language or alternative formats.
  • Linking: Connect information from the ePI to trusted external resources (e.g., patient leaflets, educational materials).

Each Lens configuration reflects a functional goal — for instance:

  • Support patient understanding of dosage and safety information
  • Assist clinicians in quickly identifying contraindications
  • Enable caregivers to manage medication safely for dependents

Key Functional Scenarios

Scenario Description Primary Users
Personalized ePI View A patient accesses the ePI for a prescribed medicine; the Lens highlights information relevant to their age, condition, or treatment plan. Patient
Clinical Consultation Support A healthcare professional reviews ePI content filtered to clinical safety aspects (e.g., contraindications, interactions) before prescribing. HCP
Medicine Use Education A caregiver views simplified, visual, or multilingual ePI formats to support safe administration. Caregiver
Digital Leaflet Access A user scans a QR code or link to access the ePI, ensuring they always see the latest, regulator-approved version. All
Feedback Loop User feedback helps improve Lens configurations and understand which information is most useful or confusing. All

Functional Benefits

The functional design of Gravitate Health supports several key outcomes:

Functional Area Expected Benefit
Personalization Tailors information to individual needs, improving comprehension and relevance.
Engagement Increases user interaction with medicine information through accessible and context-aware design.
Safety Helps prevent misuse or misunderstanding by emphasizing critical warnings.
Empowerment Encourages active participation in treatment decisions and self-management.
Continuity of Care Enables consistent understanding of medicine information across patients, caregivers, and professionals.

Non-Functional Aspects (Supporting Conditions)

While the focus of this analysis is functional, certain enabling conditions are critical for success:

  • Trust: The ePI must remain an authentic, regulator-approved source.
  • Accessibility: Content must be understandable to diverse audiences and usable across devices.
  • Interoperability: ePI should link seamlessly to digital health services and patient records.
  • Sustainability: The functional model should adapt as ePI formats and regulations evolve.

Summary

The functional perspective of Gravitate Health emphasizes how ePI is used in practice — not just how it is stored or transmitted.
Through the Lens concept, Gravitate Health enables meaningful personalization of trusted information, supporting:

  • Safer medicine use
  • Better communication between patients and professionals
  • Informed, empowered healthcare decisions

In this way, the ePI becomes not just a document, but a living, user-centered information service.
