False negative AUDIT screening results among patients in rural primary care settings.

: The objective of this study was to examine the incidence of false-negative screening results on a tool measuring alcohol use - the United States Alcohol Use Disorder Identification Test Consumption (US-AUDIT-C).: A sample of patients (n = 4,023) in Alabama completed the US-AUDIT-C prior to a medical visit as part of a screening, brief intervention, and referral to treatment (AL-SBIRT) program. We calculated the incidence of false negative US-AUDIT-C screens based on recommendations for safe alcohol consumption.: The false negative screening rate on the US-AUDIT-C was 1%. The false negative screening rate for (a) males aged > 65 years in the AL-SBIRT program was 0.64%, (b) males aged 18-65 years was 2.79%, and (c) all females was 2.29%.: Increasing alcohol-consumption-related health education and reducing the stigma of discussing alcohol consumption habits is an important step toward improving patient health. Clinicians can more accurately screen and provide brief intervention services for alcohol misuse by training on US-AUDIT-C response patterns.
