Summary
Drug usage evaluation (DUE) systems can provide physicians feedback on prescribing patterns. Upgrading these systems can improve prescribing quality through better data analysis and physician insights.
Area of Science:
- Health Informatics
- Clinical Pharmacy
- Health Services Research
Background:
- Drug usage evaluation (DUE) is crucial for physician feedback on prescribing.
- Computerized systems are vital for collecting and organizing prescribing data for DUE.
- Existing systems often have limitations in data quality and analytical capabilities.
Purpose of the Study:
- To define information requirements for computerized DUE systems.
- To survey and assess current computerized prescribing data systems.
- To propose enhancements for improving DUE processes via system design.
Main Methods:
- Literature review and analysis of existing computerized DUE information systems.
- Assessment of system capabilities against defined prescribing information requirements.
- Identification of shortcomings in patient identification, database design, and analytical software.
Main Results:
- Several DUE information systems exist with varying capacities for population-based prescribing quality evaluation.
- Common system deficiencies include patient identification issues, database design flaws, and inadequate analytical software.
- Existing systems require significant upgrades to meet comprehensive DUE needs.
Conclusions:
- Enhanced DUE information systems can empower physicians with data for rational prescribing.
- System upgrades are necessary to improve the quality and efficiency of drug usage evaluation.
- Optimized systems facilitate the development of evidence-based prescribing guidelines.
