Summary
A new web-based interface makes complex decision models accessible to more users. This tool enhances clinical decision support and guideline development by enabling easier access to cost-effectiveness analyses for preventing sudden cardiac death.
Area of Science:
- Health Informatics
- Decision Analysis
- Public Health
Background:
- Decision models are valuable for clinical guidelines and decision support.
- Widespread adoption is hindered by a lack of accessible, user-friendly, platform-independent software.
- Geographically dispersed users require easy access without extensive training.
Purpose of the Study:
- To develop a World Wide Web-based interface for accessing previously developed decision models.
- To address limitations in software accessibility and user-friendliness for decision support tools.
- To demonstrate a method for providing distributed decision support to remote users.
Main Methods:
- Developed a web-based interface for interacting with decision models.
- Used a model evaluating cost-effectiveness of sudden cardiac death prevention strategies as an example.
- Enabled users to modify input variables, perform sensitivity/threshold analyses, and view dynamic results via a web browser.
Main Results:
- The web interface provides platform-independent access to decision models.
- Users can interact with models, conduct analyses, and view results dynamically.
- Linkages to model explanations and evidence tables are provided.
Conclusions:
- The web interface offers practical and economical distributed decision support.
- It increases the utility of decision models by broadening user access.
- Facilitates incorporation of systematic analyses into policy and clinical decisions.
