A new real-time interface connects Computerized Physician Order Entry (CPOE) systems directly to Clinical Information Systems (CIS) Medication Administration Records (MAR). This integration eliminates duplicate medication entries and improves efficiency for intensive care unit (ICU) nurses.

Area of Science:

  • Health Informatics
  • Clinical Information Systems
  • Pharmacy Systems Integration

Background:

  • Previous attempts to interface Clinical Information Systems (CIS) with Pharmacy systems in intensive care units (ICUs) faced challenges.
  • Manual charting of medications in the CIS Medication Administration Record (MAR) before pharmacy system entry led to duplicate entries and medical record confusion.

Purpose of the Study:

  • To implement and evaluate a real-time interface between a Computerized Physician Order Entry (CPOE) system and a CIS in ICUs.
  • To resolve issues of duplicate medication entries and improve workflow efficiency for ICU nurses.

Main Methods:

  • Developed and interfaced the Patient Care Expert (PCX) web-based CPOE system with a CareVue CIS in 10 ICUs.
  • All medication orders from CPOE were transmitted directly to the CIS MAR upon physician authentication.

  • The system utilized an existing CIS interface specification for Pharmacy systems.

    • Main Results:

    • Over 40,000 ICU medication, IV infusion, and IV drip orders were automatically transferred in three months.
    • The interface successfully eliminated manual order transcription and medication entry errors.
    • Improved ICU nurse efficiency and satisfaction were reported.

    Conclusions:

    • A real-time CPOE to CIS MAR interface effectively solves the problem of duplicate medication entries in ICUs.
    • This integration streamlines medication management, enhances data accuracy, and improves the user experience for clinical staff.
