Pharmacy information system for a health maintenance organization

Area of Science:

• Health Informatics
• Pharmacy Management
• Health Services Research

Background:

• Health Maintenance Organizations (HMOs) require efficient pharmacy management systems.
• Existing systems may lack comprehensive drug utilization tracking.
• Computerized solutions offer potential for enhanced data analysis and reporting.

Purpose of the Study:

• To describe a newly developed computerized pharmacy system for an HMO.
• To detail the system's coding scheme and data processing capabilities.
• To present the system's generated reports and discuss its relevance to HMO pharmacy operations.

Main Methods:

• Development of a coding scheme for formulary drugs and prescribing information.
• Implementation of a computer system for processing pharmacy data.
• Generation of reports on drug dispensing frequency, patient counts, and age-sex distributions.

Main Results:

• The system has been operational for nearly three years.
• Reports provide detailed insights into drug usage patterns within the HMO.
• Data includes frequency of drugs dispensed and patient demographics for specific medications.

Conclusions:

• Computerized pharmacy systems can effectively manage and analyze drug utilization in HMOs.
• The described system offers valuable data for operational improvements and cost management.
• System requirements, maintenance, and cost estimates are crucial for successful implementation.
