The Geriatrics Research Instrument Library (GRIL) integrates data from multiple geriatric health studies, enabling researchers to easily find and use measurement instruments for data collection and management.

Area of Science:

  • Geriatric health research
  • Health informatics
  • Data management

Background:

  • Multi-factorial geriatric health conditions require standardized measurement instruments.
  • Existing clinical study data management systems lack unified instrument libraries.
  • A need exists for a centralized, accessible repository of geriatric health measurement tools.

Purpose of the Study:

  • To develop a Web-based repository, the Geriatrics Research Instrument Library (GRIL).
  • To integrate features from separate clinical study data management systems.
  • To facilitate browsing, searching, and selection of measurement instruments for geriatric health studies.

Main Methods:

  • Created a common semantic model for database integration.
  • Mapped existing systems to the unified model.

  • Identified and resolved database schema conflicts (table and attribute levels) using a conflict taxonomy and mapping schema.

    • Main Results:

    • Successfully developed and launched the Geriatrics Research Instrument Library (GRIL).
    • Resolved critical table-level conflicts, including name and relationship differences.
    • Enabled users to print selected instruments or generate downloadable microcomputer database applications.

    Conclusions:

    • Integration of applications allows for feature sharing and cross-fertilization.
    • Metadata model unification is essential for successful application integration.
    • GRIL enhances data collection and management for geriatric health research.
