Area of Science:

  • Pharmacy
  • Health Informatics
  • Artificial Intelligence in Healthcare

Background:

  • Computer-assisted decision making is increasingly vital in complex health-related choices.
  • Familiarity with expert system technology is crucial for pharmacists due to its potential role in future pharmacy practice.

Purpose of the Study:

  • To describe RXPERT, a prototype expert system for ambulatory formulary decision-making.
  • To illustrate the application of expert systems in supporting pharmacy decision-making.
  • To provide basic information on expert-system technology.

Main Methods:

  • Development of the RXPERT prototype, a computer-based expert system.
  • Description of knowledge-acquisition and knowledge-engineering techniques.
  • Explanation of expert system characteristics and structure.

Main Results:

  • RXPERT models the decision-making processes for ambulatory formulary management.
  • The system demonstrates how expert systems can support individual committee members in drug product assessment.
  • Potential advantages include making decision-making explicit, consistent, duplicable, and easy to update.

Conclusions:

  • Decision-support expert systems show potential utility for pharmacists in complex decision-making scenarios.
  • While RXPERT is a prototype, its development process highlights the practical application of expert systems.
  • Expert systems can serve as valuable tools to augment, not replace, human decision-makers.
