Brief motivational feedback improves post-incarceration treatment contact among veterans with substance use disorders

OBJECTIVES To test the efficacy of providing brief motivational feedback to increase post-incarceration substance use disorders (SUD) treatment contact. DESIGN Randomized clinical trial (feedback vs. control) with a 2-month post-incarceration follow-up. PARTICIPANTS Veterans (N = 73) incarcerated in a county jail system who met SUD diagnostic criteria. MEASURES Baseline assessment included the Addiction Severity Index, the Form-90 assessment of recent alcohol use, and a DSM-IV SUD criteria checklist. The primary outcome was Veterans Administration (VA) appointments. Secondary outcomes were the Addiction Severity Index-Followup and the Treatment Services Review. INTERVENTION All participants received baseline assessment. The feedback condition received personalized feedback and encouragement to explore ambivalence about change and treatment in a single interview. RESULTS Participants receiving feedback were more likely to schedule appointments at a VA addictions clinic within 60 days of their jail release dates (67 vs. 41%; P < 0.03). Though differences were not statistically significant, more feedback participants attended addictions clinic appointments (47 vs. 32%; ns) and were retained in addictions treatment at 90 days (31 vs. 14%; P < 0.08). Treatment appointments were more likely when intervention occurred close to release. Loss of participants to post-release follow-up interviews was >50%, limiting power to detect significant differences by self-report. CONCLUSION Brief motivational feedback shows promise as a way to link incarcerated individuals to SUD treatment services.

Binge drinking among female veterans affairs patients: Prevalence and associated risks

This study evaluated the prevalence and associated risks of binge drinking, defined as having > or = 4 drinks on an occasion in the past year, in a female patient population. Of 1,259 female Veterans Affairs patients surveyed, 780 reported drinking alcohol in the past year, and 305 (24% of respondents, 39% of drinkers) reported binge drinking in the past year; 84 (11% of drinkers) had done so monthly or more often. Age-adjusted logistic regression analyses indicated that women who reported past-year binge drinking monthly or more often reported significantly increased odds of morning drinking (odds ratio [OR] = 40.3), others worrying about their drinking (OR = 38.6), arguments after drinking (OR = 13.5), hepatitis or cirrhosis (OR = 3.1), frequent injuries (OR = 2.6), smoking (OR = 3.7), drug use (OR = 22.2), and multiple sexual partners (OR = 4.6).

Smoking cessation treatment among dually diagnosed individuals: Preliminary evaluation of different pharmacotherapies

This descriptive, observational pilot study evaluated a smoking cessation intervention using open-label bupropion and nicotine replacement within an addiction treatment center for patients with high rates of comorbid psychiatric diagnoses. Participants were 115 veterans receiving substance abuse treatment at a Veterans Administration outpatient program who voluntarily sought smoking cessation treatment. Three fourths of participants had a psychiatric diagnosis in addition to substance dependence (i.e., dual diagnosis). The intervention consisted of a weekly smoking cessation therapy group and pharmacotherapy as determined by participant and clinician preference (none, nicotine replacement only, bupropion only, or combined nicotine and bupropion). A total of 47 participants (40.9%) completed four group smoking cessation sessions, and 17 (14.8%) completed eight sessions. Of these participants, 27 (23.5%) had breath carbon monoxide (CO) levels <9 ppm (indicating short-term abstinence) at session 4, and nine (7.8%) had CO levels <9 ppm at session 8. Participants who received nicotine replacement alone or with bupropion attended more sessions than did subjects who did not receive nicotine replacement. Participants receiving combined medications had greater reductions in CO levels at session 4 than did the other participants. There was no evidence of increased use of other substances during smoking cessation treatment. These findings indicate that many dually diagnosed individuals are willing to attempt smoking cessation with appropriate pharmacotherapy and achieve reductions in CO measures, but only minimal success was observed with respect to cessation. Additional research is needed to assess medication effects in randomized trials, to explore effects of more intensive treatments, and to assess possible harm reduction from smoking interventions within this population.

The TWEAK is weak for alcohol screening among female Veterans Affairs outpatients.

BACKGROUND The optimal brief questionnaire for alcohol screening among female patients has not yet been identified. This study compared the performance of the TWEAK (tolerance, worried, eye-opener, amnesia, cutdown), the Alcohol Use Disorders Identification Test (AUDIT), and the AUDIT Consumption (AUDIT-C) as self-administered screening tests for hazardous drinking and/or active alcohol abuse or dependence among female Veterans Affairs (VA) outpatients. METHODS Women were included in the study if they received care at VA Puget Sound and completed both a self-administered survey containing the AUDIT and TWEAK screening questionnaires and subsequent in-person interviews with the Alcohol Use Disorders and Associated Disabilities Interview Schedule. Sensitivities, specificities, positive and negative likelihood ratios, and areas under Receiver Operating Characteristic curves were computed for each screening questionnaire compared with two interview-based comparison standards: (1) active DSM-IV alcohol abuse or dependence and (2) hazardous drinking and/or active DSM-IV alcohol abuse or dependence, the more appropriate target for primary care screening. RESULTS Of 393 women who completed screening questionnaires and interviews, 39 (9.9%) met diagnostic criteria for alcohol abuse or dependence, and 89 (22.7%) met criteria for hazardous drinking or alcohol abuse or dependence. The TWEAK had relatively low sensitivities (0.62 and 0.44) but adequate specificities (0.86 and 0.89) for both interview-based comparison standards, even at its lowest cut-point (>/=1). The AUDIT and AUDIT-C were superior, with the following areas under the receiver operating characteristic curve for active alcohol abuse or dependence and hazardous drinking and/or active alcohol abuse or dependence, respectively: AUDIT, 0.90 [95% confidence interval (CI), 0.85-0.95] and 0.87 (95% CI, 0.84-0.91); AUDIT-C, 0.91 (95% CI, 0.88-0.95) and 0.91 (95% CI, 0.88-0.94); and TWEAK, 0.76 (95% CI, 0.66-0.86) and 0.67 (95% CI, 0.60-0.74). CONCLUSIONS The TWEAK has low sensitivity as an alcohol-screening questionnaire among female VA outpatients and should be evaluated further before being used in other female primary care populations. The three-item AUDIT-C was the optimal brief alcohol-screening questionnaire in this study.
