Study Suggests Validated Alcohol Screening Questionnaire Not Enough to Ensure Quality of Screening


BACKGROUND:
A National Commission on Prevention Priorities designated alcohol screening and brief alcohol interventions the third highest U.S. adult prevention priority. The VA healthcare system implemented routine screening for alcohol misuse in 2004, and since 2006 has required that the Alcohol Use Disorders Identification Test - Consumption Questions (AUDIT-C) be used for screening. Nationwide, more than 90% of VA outpatients are screened with the AUDIT-C, and rates of brief alcohol counseling in VA are increasing. The AUDIT-C has been validated when interviewer-administered – and when completed as a mailed questionnaire with results shared with primary care providers – but little is known about its performance when implemented as part of routine clinical care. This study evaluated the quality of clinical alcohol screening among 6,861 VA outpatients from 2007-2008 by comparing AUDIT-C results documented during routine clinical care to AUDIT-C results from a confidential mailed survey completed within 90 days of the clinical screen. Investigators also evaluated factors associated with discordance between the results of clinical and survey alcohol screens.

FINDINGS:

  • Of the national sample, 61% of VA outpatients who screened positive for alcohol misuse with the AUDIT-C on mailed surveys screened negative during the same time period with the AUDIT-C in VA outpatient clinical settings.
  • Overall, 11% of Veterans screened positive on the survey screen vs. only 5.7% on the clinical screen.
  • Patients who screened positive on the AUDIT-C survey were much more likely to have discordant clinical screening results, e.g., among patients whose clinical screens indicated no alcohol use in the past year, 22% reported drinking on the survey screens.
  • Discordance was significantly increased among African American Veterans compared with white Veterans. There were also differences across VA networks: the proportion of Veterans with positive survey screens who had negative clinical screens varied from 43% to 100% across different networks.

LIMITATIONS:

  • Mailed surveys may not be the optimal comparison standard, e.g. compared to in-depth interviews.
  • The study sample was too small to evaluate facility-level variations. Also, data were not collected on alcohol screening procedures across VA networks, so investigators could not determine whether differences in alcohol screening implementation accounted for differences in discordance.

IMPLICATIONS:

  • Findings suggest that mandating the clinical use of a validated alcohol screening questionnaire may not ensure high-quality screening, and that many Veterans who could benefit from brief alcohol counseling are being missed.

What are HSR&D Publication Briefs?

HSR&D requires notification by HSR&D-funded investigators about all articles accepted for publication. These journal articles are reviewed by HSR&D and publication briefs or summaries are written for a select number of articles that are then forwarded to VHA Central Office leadership to keep them informed about important findings or information. Articles to be summarized are selected by HSR&D based on timeliness of the findings, interest of leadership, or potential impact on the organization. Publication briefs are written for only a small number of HSR&D published articles. Visit the HSR&D citations database for a complete listing of HSR&D articles and presentations.
