    A computer-based prompt system significantly reduced the number of missed laboratory tests. This clinical decision support tool improved the ordering of routine investigations, enhancing patient care.

    Area of Science:

    • Clinical Informatics
    • Laboratory Medicine
    • Health Services Research

    Background:

    • Ordering routine laboratory investigations is crucial for patient diagnosis and management.
    • Inconsistent ordering practices can lead to missed tests and suboptimal care.
    • Computer-based systems offer potential solutions for improving clinical workflows.

    Purpose of the Study:

    • To evaluate the effectiveness of a computer-based prompt system in improving the ordering frequency of routine laboratory investigations.
    • To assess the impact of the prompt system on the number of missed laboratory tests.

    Main Methods:

    • Implementation of a computer-based prompt system integrated into the electronic health record.
    • Prospective data collection on the ordering of specific routine laboratory tests before and after system implementation.

  • Analysis of the number of tests not ordered in two distinct study periods.

    • Main Results:

    • In the first study, the number of routine laboratory tests not ordered decreased from 68 to 16.
    • In the second study, the number of tests not ordered fell substantially from 130 to 19.
    • The computer-based prompt system demonstrated a significant positive impact on test ordering compliance.

    Conclusions:

    • Computer-based prompt systems are effective tools for enhancing the ordering of essential laboratory investigations.
    • Implementing such systems can reduce the frequency of missed diagnostic tests, potentially improving patient outcomes.
    • Clinical decision support tools play a vital role in optimizing laboratory test utilization.
