Area of Science:

  • Pharmaceutical Sciences
  • Drug Development
  • Usability Engineering

Background:

  • The drug development community requires efficient access to excipient safety and toxicity data.
  • The Safety and Toxicity of Excipients for Paediatrics (STEP) database was developed to meet this need.
  • Usability testing is essential to ensure database effectiveness for end-users.

Purpose of the Study:

  • To validate the usability of the user-designed STEP database.
  • To identify design vulnerabilities and areas for improvement.
  • To assess user satisfaction with the database.

Main Methods:

  • An evaluation framework was developed to assess usability.
  • Participants completed scenario-based tasks and provided feedback.
  • Failure Mode Effect Analysis (FMEA) was used to prioritize improvements.

Main Results:

  • Several design vulnerabilities were identified, impacting tasks like data retrieval and complex queries.
  • Critical attributes affecting usability included content, navigation, search features, and end-user considerations.
  • User feedback highlighted challenges with result limitations and database registration.

Conclusions:

  • The evaluation framework effectively assessed database usability and user satisfaction.
  • The study provides initial support for the STEP database's usability.
  • Recommendations will guide database refinement to enhance usability and encourage user engagement.
