Cost-effective criteria for glucose screening.

    Summary

    A new screening approach for gestational diabetes mellitus (GDM) could save costs. Screening women aged 24 and older with a glucose level of 150 mg/dL or higher is a potential alternative to universal screening.

    Area of Science:

    • Obstetrics and Gynecology
    • Endocrinology
    • Public Health

    Background:

    • Gestational diabetes mellitus (GDM) affects pregnant individuals.
    • Effective and cost-efficient screening methods are crucial for early GDM detection and management.
    • Current universal screening protocols may incur significant healthcare costs.

    Purpose of the Study:

    • To evaluate the cost-effectiveness of modified screening criteria for gestational diabetes.
    • To identify a more targeted approach for GDM screening to reduce healthcare expenditure.
    • To determine if a higher glucose threshold and age restriction can maintain diagnostic accuracy.

    Main Methods:

    • A prospective study involving 1012 pregnant patients.
    • Initial glucose screening between 26-30 weeks of gestation using a 50-g oral glucose load and one-hour plasma glucose measurement.
    • Patients with a glucose screen ≥ 130 mg/dL underwent a standard three-hour oral glucose tolerance test.

    Main Results:

    • The incidence of GDM was 2.4% (24 of 1012).
    • Only one case of GDM was detected with a glucose screen below 150 mg/dL.
    • 88% of GDM cases (21 of 24) were diagnosed in patients ≥ 24 years old with a glucose screen ≥ 150 mg/dL.
    • This targeted screening strategy reduced diagnostic costs by 40% compared to universal screening at 130 mg/dL.

    Conclusions:

    • Screening patients aged 24 years or older with a glucose threshold of 150 mg/dL is a potential cost-effective alternative to universal GDM screening.
    • This modified approach may optimize resource allocation in GDM diagnosis.
    • Further research could validate this targeted screening strategy in diverse populations.
