Health Information Technology and Care Coordination: The Next Big Opportunity for Informatics?

Yearbook of medical informatics·2015

Area of Science:

  • Pharmacology
  • Clinical Pharmacy
  • Health Informatics

Background:

  • Drug-drug interactions (DDIs) pose a significant risk to patient safety.
  • Existing screening methods may not fully account for individual patient physiological responses.
  • Automated systems are needed to efficiently identify potential DDIs.

Purpose of the Study:

  • To develop and evaluate a program for automatic screening of medication profiles for DDIs.
  • To incorporate patient laboratory parameters into DDI alert generation.
  • To assess the clinical impact and acceptance of the automated DDI screening tool.

Main Methods:

  • Development of a DDI screening program incorporating patient laboratory data.
  • Implementation of a knowledge base editor for system maintenance.

  • Evaluation of the program in two satellite pharmacies over a 3-week period.

    • Main Results:

    • The program generated 160 alerts during the evaluation period.
    • Five alerts (one per 500 patient-days) led to changes in patient therapy due to potentially very serious interactions.
    • Three additional alerts resulted in adjustments to medication administration times.

    Conclusions:

    • The automated DDI screening program effectively identified potentially serious drug interactions.
    • Incorporating laboratory parameters enhances the clinical relevance of DDI alerts.
    • The program is well-received and suitable for routine clinical use in pharmacy settings.
