EDC: a microcomputer program to record and calculate expected date of confinement.

K W Chan

    The British Journal of Clinical Practice
    |November 1, 1989
    PubMed
    Summary

    A new microcomputer program calculates the expected date of confinement (EDC) by averaging up to 19 clinical parameters. This tool improves accuracy when the last menstrual period is unknown or unreliable for estimating gestational age.

    Area of Science:

    • Obstetrics and Gynecology
    • Medical Informatics
    • Reproductive Health

    Background:

    • Accurate estimation of the expected date of confinement (EDC) is crucial in obstetrical care.
    • Traditional EDC calculation relies on the last menstrual period (LMP), which can be inaccurate or unknown.
    • Clinical examinations offer alternative methods for estimating gestational age.

    Purpose of the Study:

    • To develop a microcomputer program for computing the expected date of confinement (EDC).
    • To integrate and average multiple clinical parameters for more reliable EDC estimation.
    • To create a system for recording clinical data used in EDC calculations.

    Main Methods:

    • Development of a microcomputer program to calculate EDC.
    • Inclusion of up to 19 clinical parameters for EDC estimation.
    • Averaging multiple EDC estimates to produce a final result.
    • Displaying the result as gestational age in weeks.

    Main Results:

    • The program computes EDC by averaging multiple clinical parameters.
    • It provides a more accurate EDC when LMP data is unreliable.
    • A register is maintained for tracking pregnancy data and EDC calculations.
    • The system allows for analysis of the dispersion of EDCs from various clinical methods.

    Conclusions:

    • The developed microcomputer program enhances the accuracy of expected date of confinement (EDC) calculation.
    • It offers a valuable tool for obstetrical care, especially when LMP data is compromised.
    • The program facilitates comprehensive data management and analysis of gestational age estimation methods.
