Treating asthma by the guidelines: developing a medication management information system for use in primary care

Area of Science:

• Clinical Informatics
• Pediatric Pulmonology
• Health Information Systems

Background:

• Asthma medication management requires adherence to clinical guidelines for optimal patient outcomes.
• Existing systems may lack automated, patient-specific feedback for practitioners.
• The 1997 National Asthma Education and Prevention Program (NAEPP) guidelines provide a framework for asthma care.

Purpose of the Study:

• To develop and assess an automated asthma medication management information system (MMIS).
• To provide patient-specific guidance based on 1997 NAEPP guidelines.
• To evaluate the system's impact on asthma medication prescribing practices in primary care.

Main Methods:

• Developed and implemented an internet-accessible, centralized MMIS in pediatric primary care.
• Collected detailed patient asthma medication data and practitioner-reported severity.
• Utilized a system algorithm to compare actual pharmacotherapy to guideline-recommended, severity-appropriate medications.

Main Results:

• The MMIS produced a valid feedback report for 83% of patient visits.
• Missing data constituted 60% of system error cases.
• Practitioners prescribed severity-appropriate medications in 60% of cases, with a tendency towards over-prescribing (22%) rather than under-prescribing (5%).

Conclusions:

• The developed MMIS is a viable tool for supporting guideline-adherent asthma medication management.
• The system identified opportunities for improving medication appropriateness in pediatric asthma care.
• Further refinement of data collection may reduce error rates and enhance system utility.
