Drinking behavior, remission, and relapse: the Rand Report revisited

Varenicline Reduces Alcohol Intake During Repeated Cycles of Alcohol Reaccess Following Deprivation in Alcohol-Preferring (P) Rats

BACKGROUND

Most alcoholics experience periods of voluntary alcohol abstinence or imposed alcohol deprivation followed by a return to alcohol drinking. This study examined whether varenicline (VAR) reduces alcohol intake during a return to drinking after periods of alcohol deprivation in rats selectively bred for high alcohol drinking (the alcohol preferring or "P" rats).

METHODS

Alcohol-experienced P rats were given 24-hour access to food and water and scheduled access to alcohol (15% and 30% v/v) for 2 h/d. After 4 weeks, rats were deprived of alcohol for 2 weeks, followed by reaccess to alcohol for 2 weeks, and this pattern was repeated for a total of 3 cycles. Rats were fed either vehicle (VEH) or VAR, in doses of 0.5, 1.0, or 2.0 mg/kg BW, at 1 hour prior to onset of the daily alcohol reaccess period for the first 5 days of each of the 3 alcohol reaccess cycles.

RESULTS

Low-dose VAR (0.5 mg/kg BW) reduced alcohol intake during the 5 days of drug treatment in alcohol reaccess cycles 1 and 2. Higher doses of VAR (1.0 mg/kg BW and 2.0 mg/kg BW) reduced alcohol intake during the 5 days of treatment in all 3 alcohol reaccess cycles. The decrease in alcohol intake disappeared with termination of VAR treatment in all alcohol reaccess cycles.

CONCLUSIONS

The results demonstrate that VAR decreases alcohol intake during multiple cycles of alcohol reaccess following alcohol deprivation in rats and suggests that it may prevent a return to heavy alcohol drinking during a lapse from alcohol abstinence in humans with alcohol use disorder.

Older adult treatment outcome following elder-specific inpatient alcoholism treatment

This study examined multidimensional 6-month outcomes of elder-specific inpatient alcoholism treatment for 90 participants over the age of 55. At baseline, physical health functioning was similar to that reported by seriously medically ill inpatients in other studies while psychosocial functioning was worse, and nearly one third of the sample had comorbid psychiatric disorders. Based on 6-month outcomes, participants were classified into the following groups: Abstainers, Non-Binge Drinkers, and Binge Drinkers. The groups did not differ on any baseline measures (demographics, drinking history, alcohol symptoms and age of onset, comorbidity, or length of treatment). General health improved between baseline and follow-up for all groups. Psychological distress decreased for Abstainers and Non-Binge Drinkers, but did not change for Binge Drinkers. Results suggest that a large percentage of older adults who receive elder-specific treatment attain positive outcomes across a range of outcome measures.

Alcoholism among hospital employees

An employee alcoholism service for hospital workers is described. Sixty-eight alcoholic workers identified over a 3 1/2 year period are assessed for current status as to activity in the service, work status, and drinking status by a chart review. The principle route of referral was via the employee health service (EHS) and a medical problem (63%) versus a supervisor or self-referral. Fifty-three percent of the workers are active in the service, 31% have had no contact, 12% are terminated from the job, and 4% are deceased. Of the active cases, 75% are abstinent. Active status in the service is highly associated with a supervisor or self-referral rather than an EHS referral. Self- and supervisor referrals to the service increased substantially after the initiation of an employee assistance program in the hospital.

Benefit--cost methodology in the evaluation of therapeutic services for alcoholism

Benefit--cost analysis as a form of "social profitability analysis" can be a powerful tool in the overall evaluation of alcoholism treatment efforts. Alcoholism treatment potentially leads to a multiplicity of benefits in addition to sobriety. Benefit--cost analysis provides a methodology for converting many of these diverse benefits into a common metric (dollars), thereby allowing the comparison of aggregate benefits and treatment costs. The analysis thus leads to the expression of treatment outcome in terms of the return on investment. A benefit--cost analysis conducted on 3034 clients from the Oklahoma data base indicated a return to society of $1.98 for every $1 invested in alcoholism treatment. Such data may represent a critical portion of the information required for responsible resource allocation decisions.
