Researchers propose creating electronic trial banks to improve access to randomized clinical trial (RCT) data. These structured databases would contain 162 essential data points for systematic reviews and clinical decision support.

Area of Science:

  • Clinical Research Informatics
  • Evidence-Based Medicine
  • Health Data Management

Background:

  • Randomized clinical trial (RCT) results are challenging to locate, interpret, and implement in clinical practice.
  • Current text-based reporting of RCTs hinders efficient data retrieval and application.
  • A novel approach is proposed to enhance RCT reporting through structured electronic knowledge bases, termed trial banks.

Purpose of the Study:

  • To determine the essential information required for comprehensive trial-bank reports.
  • To identify data necessary and sufficient for systematic reviewing of RCTs.
  • To facilitate the development of computer-understandable RCT data repositories.

Main Methods:

  • The competency decomposition method was employed to analyze the systematic reviewing process.

  • The systematic reviewing task was broken down into four primary tasks and 62 subtasks.
  • Information requirements were identified based on the subtasks necessary for systematic review completion.

    • Main Results:

    • A total of 162 distinct types of trial information were identified as necessary and sufficient.
    • These data types encompass trial design, execution, administration, and results.
    • The identified items provide a comprehensive framework for structured RCT reporting.

    Conclusions:

    • Publishing RCT data in trial banks, comprising 162 items, enables computer-understandable critical appraisal and synthesis.
    • Shared, updated trial banks can power decision-support systems for clinicians.
    • These systems can enhance the management, synthesis, and application of RCT evidence in clinical care.
