Validation of the primary care alcohol severity measure.
Alcohol-related disorders are common in primary care settings; many primary care physicians are ill-equipped to manage patients with alcohol-related disorders. The objective of this prospective cohort study was to develop and validate a patient-based measure, the Primary Care Alcohol Severity Measure, to determine which primary care patients with alcohol-related disorders would benefit from referral to alcohol treatment services. Four Boston-area Department of Veterans Affairs ambulatory care clinics were chosen as study sites. Two hundred seventy-eight male patients, mean age 55.5 years, 89.9% Caucasian, 42.5% married, all with CAGE Questionnaire scores greater than or equal to 2 and drinking within past year, participated in the study. We developed a multidimensional, 30-item measure that contained 2 subscales that assessed 2 symptom clusters of alcohol-related disorders: Physical and Behavioral. Each subscale's score was higher (more severe) for patients with a current Diagnostic and Statistical Manual of Mental Disorders, Third Edition, Revised diagnosis of alcohol dependence or abuse: P < .01 for the physical subscale and P < .0001 for the behavioral subscale. Patients with more physical symptoms had poorer physical and mental health status, whereas patients with more behavioral symptoms had poorer mental health status. Scores on the 2 subscales, along with age and history of prior treatment, predicted the use of alcohol treatment services in the following year: c = 0.90 in logistic regression. The Primary Care Alcohol Severity Measure is a valid measure of alcohol severity in primary care patients and predicts the use of alcohol treatment services. It is relatively brief and easy to use, requiring only standard medical history items and patient reports of behavioral symptoms. It may be a useful tool to improve the quality of care for primary care patients with alcohol-related disorders.
