    The CAGE questionnaire effectively screens for alcohol abuse, showing 85% sensitivity and 89% specificity. However, physicians detected only 63% of alcohol abusers, highlighting a gap in clinical practice.

    Area of Science:

    • Medical Research
    • Clinical Screening
    • Addiction Medicine

    Background:

    • Alcohol abuse is a significant public health issue.
    • Physician detection rates for alcohol abuse are often low.
    • Effective screening tools are needed to improve early identification.

    Purpose of the Study:

    • To evaluate the CAGE questionnaire's effectiveness in detecting alcohol abuse.
    • To compare the CAGE questionnaire with other biochemical markers.
    • To assess physician detection and intervention rates for alcohol abuse.

    Main Methods:

    • Prospective study of 518 patients in a community teaching hospital.
    • Utilized the CAGE questionnaire as a primary screening instrument.
    • Validated findings with the Michigan Alcoholism Screening Test, chart review, and alcohol consumption analysis.

    Main Results:

    • The CAGE questionnaire demonstrated high sensitivity (85%) and specificity (89%).
    • Biochemical markers (MCV, GGT, liver transaminases) showed low sensitivity.
    • Physicians detected only 63% of alcohol abusers, addressing the issue in 24% of cases.

    Conclusions:

    • The CAGE questionnaire is a simple, sensitive, and specific tool for screening alcohol abusers.
    • There is a significant gap between patient alcohol abuse and physician detection/intervention.
    • Improving physician awareness and utilization of screening tools like CAGE is crucial.
