What can general medical providers do for hospitalized patients with alcohol dependence after discharge?

Influence of a targeted performance measure for brief intervention on gender differences in receipt of brief intervention among patients with unhealthy alcohol use in the Veterans Health Administration

AIMS

Women are less likely than men to receive brief intervention (BI) for unhealthy alcohol use. In 2007, the U.S. Veterans Health Administration (VA) used a national performance measure to implement BI. Although AUDIT-C scores ≥3 for women and ≥4 for men optimize sensitivity and specificity for identifying unhealthy alcohol use, VA's performance measure required BI only among a targeted subgroup defined by a non-gender-specific score threshold (AUDIT-C ≥5). This may have influenced gender differences in receipt of BI among those optimally eligible for BI. Therefore, we evaluate differences in proportions of women and men offered BI before and after BI implementation.

METHODS

National secondary chart review data (7/06-6/10) identified all outpatients with unhealthy alcohol use for whom BI would be indicated (AUDIT-C ≥3 women, ≥4 men). Logistic regression, including a time-by-gender interaction, estimated the prevalence and 95% confidence interval (CI) of BI for women and men pre- and post-implementation.

FINDINGS

Among patients optimally eligible for BI (n=51,272, 8206 women and 43,066 men), the prevalence of BI increased more steeply for men than women after implementation (interaction p-value <0.0001). Pre-implementation rates of BI were 21% (95% CI, 18-24) for women and 26% (95% CI, 24-29) for men, and post-implementation rates were 32% (95% CI, 30-34) for women and 47% (95% CI, 45-49) for men.

CONCLUSIONS

Healthcare systems implementing BI with performance measures may wish to consider that specifying a single alcohol screening threshold for men and women may increase gender differences in receipt of BI among patients likely to benefit.

Prevalence of clinically recognized alcohol and other substance use disorders among VA outpatients with unhealthy alcohol use identified by routine alcohol screening

OBJECTIVE

The purpose of routine alcohol screening is to identify patients who may benefit from brief intervention, but patients who also have alcohol and other substance use disorders (AUD/SUD) likely require more intensive interventions. This study sought to determine the prevalence of clinically documented AUD/SUD among VA outpatients with unhealthy alcohol use identified by routine screening.

METHODS

VA patients 18-90 years who screened positive for unhealthy alcohol use (AUDIT-C ≥3 women; ≥4 men) and were randomly selected for quality improvement standardized medical record review (6/06-6/10) were included. Gender-stratified prevalences of clinically documented AUD/SUD (diagnosis of AUD, SUD, or alcohol-specific medical conditions, or VA specialty addictions treatment on the date of or 365 days prior to screening) were estimated and compared across AUDIT-C risk groups, and then repeated across groups further stratified by age.

RESULTS

Among 63,397 eligible patients with unhealthy alcohol use, 25% (n=2109) women and 28% (n=15,199) men had documented AUD/SUD (p<0.001). The prevalence of AUD/SUD increased with increasing AUDIT-C risk, ranging from 13% (95% CI 13-14%) to 82% (79-85%) for women and 12% (11-12%) to 69% (68-71%) for men in the lowest and highest AUDIT-C risk groups, respectively. Patterns were similar across age groups.

CONCLUSIONS

One-quarter of all patients with unhealthy alcohol use, and a majority of those with the highest alcohol screening scores, had clinically recognized AUD/SUD. Healthcare systems implementing evidence-based alcohol-related care should be prepared to offer more intensive interventions and/or effective pharmacotherapies for these patients.

Why not add consumption measures to current definitions of substance use disorders? Commentary on Rehm et al.: 'Defining substance use disorders: do we really need more than heavy use?'

The article by Rehm and colleagues in this issue of the Journal argues that diagnoses of substance use disorders should be based solely on measures of consumption. Although the authors provide convincing arguments for inclusion of consumption measures in the diagnostic criteria for substance use disorders, we do not agree that diagnostic criteria should be restricted to measures of consumption alone. Our clinical and research experience with alcohol use disorders suggests that use of consumption measures alone would fail to identify many patients whose alcohol or drug use is adversely impacting their health. Instead, we advocate-as others have done-that measures of consumption be added to current diagnostic criteria.
