Age group differences in response to treatment for problematic alcohol use

Professionals' perspectives on interventions to reduce problematic alcohol use in older adults: a realist evaluation of working elements

OBJECTIVES

This study set out to understand how (which elements), in what context and why (which mechanisms) interventions are successful in reducing (problematic) alcohol use among older adults, from the perspective of professionals providing these interventions.

DESIGN

Guided by a realist evaluation approach, an existing initial programme theory (IPT) on working elements in alcohol interventions was evaluated by conducting semistructured interviews with professionals.

SETTING AND PARTICIPANTS

These professionals (N=20) provide interventions across several contexts: with or without practitioner involvement; in-person or not and in an individual or group setting. Data were coded and links between contexts, elements, mechanisms and outcomes were sought for to confirm, refute or refine the IPT.

RESULTS

From the perspective of professionals, there are several general working elements in interventions for older adults: (1) pointing out risks and consequences of drinking behaviour; (2) paying attention to abstinence; (3) promoting contact with peers; (4) providing personalised content and (5) providing support. We also found context-specific working elements: (1) providing personalised conversations and motivational interviewing with practitioners; (2) ensuring safety, trust and a sense of connection and a location nearby home or a location that people are familiar with in person and (3) sharing experiences and tips in group interventions. Furthermore, the mechanisms awareness and accessible and low threshold participation were important contributors to positive intervention outcomes.

CONCLUSION

In addition to the IPT, our findings emphasise the need for social contact and support, personalised content, and strong relationships (both between client and practitioner, and client and peers) in interventions for older adults.

Age as a moderator of motivational interviewing and nondirective client-centered psychotherapy for alcohol use disorder: An exploratory study

BACKGROUND

Motivational interviewing (MI) is a widely used intervention applied to a host of health behaviors, including alcohol consumption among individuals with alcohol use disorder (AUD). Age is an underexplored moderator of MI for treating AUD, with the impact of comparing older individuals with their younger counterparts virtually unexplored. Also unexplored is whether age is associated with distinct mechanisms of change (e.g., motivation and self-efficacy) within treatment.

METHODS

This secondary data analysis utilizes combined data from two previous studies (total N = 228) that both aimed to test MI's mechanisms of action in the context of a goal for moderated drinking. Both studies had three conditions: MI, nondirective listening (NDL), and a self-change condition (SC). In the current analyses, the moderating impact of continuous age and age group, <51 (younger adults, YA) versus ≥51 (older adults, OA), on the impact of MI on alcohol use compared to NDL and SC were tested using generalized linear models. Age differences in confidence and commitment to reduce heavy drinking during treatment were also explored.

RESULTS

Age group by condition differences emerged, where NDL significantly reduced drinking among YA but not OA (mean -12 vs. -3 standard drinks, respectively). Among OA, MI outperformed NDL but not SC, though the effect was weak. Confidence and commitment during treatment were not significantly different across age-by-condition groups.

CONCLUSION

Findings underscore the importance of understanding the impact of age on treatment effectiveness, as providing a nondirective intervention for OA with AUD could provide suboptimal treatment. Further research is needed to explore these differential effects.

Elderly alcoholics compared to middle-aged alcoholics in outpatient treatment - 6-month follow-up

PURPOSE

This study examined 6-month drinking outcomes of elderly patients compared with middle-aged patients in a clinical sample after initiation of outpatient treatment for alcoholism.

MATERIALS AND METHODS

In a clinical prospective cohort study, 1398 consecutive patients from a municipality outpatient alcohol clinic were included. A total of 208 elderly patients aged from 60 to 82 years and 1190 middle-aged patients from 40 to 59 years participated in the study. The following psychosocial treatment interventions were offered: cognitive behavioral therapy, family therapy and supportive consultations. Using an 'intention-to-treat' method, primary outcomes included drinking outcomes (self-reported abstinence rates, drinking 3 drinks or less per day, and change in Addiction Severity Index [ASI] composite scores) during the 30 days prior to 6-month follow-up; secondary outcome was compliance to the recommended treatment.

RESULTS

Compared to middle-aged, among elderly patients a higher proportion were females (33.5% vs. 42.8%) and had a lower family/social ASI-composite score (0.17 vs. 0.12) at baseline. Higher alcohol and family/social ASI-composite scores were inversely correlated with abstinence. Elderly patients had a higher chance for abstinence compared to middle-aged patients (Odds ratio 95% [confidence interval]) 1.40 (1.03-1.92). The proportion of elderly patients that drank 3 or less drinks per day was 17.8%, compared to 10.8% among middle-aged (p < .01). Finally, elderly patients obtained a higher compliance, which was similarly associated with abstinence (OR =2.46 (1.95-3.11)).

DISCUSSION AND CONCLUSIONS

Elderly patients, who receive psychosocial outpatient treatment for alcoholism, have better 6-month outcomes within a range of drinking outcome measures compared to middle-aged patients.

Interventions in individuals with specific needs

With the growing understanding of substance use problems among special populations like women, gender minority groups, as well as in the geriatric population, there is a drive to develop sensitive interventions catering to their unique needs. This chapter is a short review of psycho-social interventions targeted towards these individuals with specific needs.

Working in tandem: The contribution of remedial programs and roadside licence suspensions to drinking and driving deterrence in Ontario

In 1998, Ontario implemented a remedial program called "Back On Track" (BOT) for individuals convicted of alcohol-impaired driving. Drivers convicted before October 2000 were exposed to a single-component program ("Edu BOT"); those convicted after participated in a multi-component program ("Full BOT"). We evaluated the impact of BOT, and the preceding 90-day roadside licence suspension, on drinking and driving recidivism, an outcome yet to be examined, using population-wide driver records. A Chi Square Test was used to compare the three-year cumulative incidence of recidivism between three historically-defined cohorts: No BOT, Edu BOT, and Full BOT. Stratified analyses by completion status and by age were also conducted. Analyses of the roadside suspension were conducted using an interrupted time series approach based on segmented Poisson/negative binomial regression. The roadside suspension was associated with a 65.2% reduction in drinking driving recidivism. In combination with indefinite suspensions for non-completion, the BOT program was also associated with a 21% decrease in drinking and driving recidivism in the three years following a CCC driving prohibition, from 8.5% to 6.7%. This reduction cannot be explained by pre-existing trends in recidivism. Conversion of the BOT program from the single-component version to the multi-component program further reduced the three-year cumulative incidence of recidivism to 5.5% (a total reduction of 35% from pre-BOT). Results provide strong converging evidence that remedial alcohol education/treatment programs in combination with other sanctions can produce substantial increases in road safety.

Treatment of alcohol use disorders in the elderly: an overview of RCTs

In this issue of International Psychogeriatrics, our research group published a paper on alcohol use disorders (AUD) in elderly adults (Kist et al., 2014). According to different authors, age of onset is an important characteristic to distinguish subgroups of patients with AUD, similar to, for example, late-onset depression (LOD) and late-onset schizophrenia (LOS). The cut off age to discriminate between early and late-onset AUD varies but is often 25 years, which is substantially younger than the cutoffs to discriminate LOD or LOS. However, in AUD, many patients started having alcohol problems much later in life, for example, after 45, 50, or even after 60 years. These very late onset patients are almost completely ignored in research. In a group of older inpatients with AUD, we found that those who started drinking heavily after 25 and after 45 years of age have similar cognitive impairments compared with their peers who started drinking before 25 years of age. Our results are counter-intuitive at first instance, but some other authors have found the same results. However, several potential limitations may also account for this result, and replication is needed before conclusions that are more definite can be drawn. In the preparation of this editorial, we found a lack of research in patients who started drinking excessive amounts of alcohol very late in life. This is in contrast with, for example, a fair amount of research in LOD and at least some research in LOS.

Substance abuse among older adults

Although the myth that older adults do not use mood-altering substances persists, evidence suggests that substance use among older adults has been underidentified for decades. The baby boom generation is unique in its exposure to, attitudes toward, and prevalence of substance use-causing projected rates of substance use to increase over the next twenty years. Given their unique biological vulnerabilities and life stage, older adults who misuse substances require special attention. Prevalence rates of substance use and misuse among older adults, methods of screening and assessment unique to older adults, and treatment options for older adults are reviewed.

Older adult problem drinkers: who presents for alcohol treatment?

OBJECTIVES

To describe a treatment population of older adults (60+ years) assessed for alcohol treatment over a 20-year period.

METHOD

Retrospective analysis of alcohol treatment assessment data relating to all older adults assessed by one UK NHS Trust Community Alcohol Team (n = 585) between April 1988 and March 2008.

RESULTS

Over the 20-year period, the number of assessments per year increased though the demographic profile of those assessed for treatment remained the same: male (62%), white ethnic origin (94%) and average age 65.7 years. The average amount of alcohol consumed per week was 102.91 units. Most were drinking alcohol on a daily basis (79%), mainly spirits (79%), at home (84%), alone (82%) and 'to reduce tension/anxiety' (22%). The average length of having had an alcohol problem was 9.7 years. Significant gender differences were found in terms of demographic profile and drinking patterns.

CONCLUSIONS

The older adults assessed for alcohol treatment were drinking in amounts comparable to the treatment population of younger adult problem drinkers, men more so than women. The majority were not reporting problems with their drinking until they were on average in their middle-to-late 50s and were therefore considered to be late onset 'reactors' rather than early onset 'survivors' of longer term heavy drinking patterns reported in earlier studies.

A review of existing treatments for substance abuse among the elderly and recommendations for future directions

Background

With population aging, there is widespread recognition that the healthcare system must be prepared to serve the unique needs of substance using older adults (OA) in the decades ahead. As such, there is an increasingly urgent need to identify efficient and effective substance abuse treatments (SAT) for OA. Despite this need, there remains a surprising dearth of research on treatment for OA.

Aims of review

This review describes and evaluates studies on SAT applied to and specifically designed for OA over the last 30 years with an emphasis on methodologies used and the knowledge gained.

Methods

Using three research databases, 25 studies published in the last 30 years which investigated the impact of SAT on OA and met specific selection criteria were reviewed.

Results

A majority of the studies were methodologically limited in that they were pre-to-post or post-test only studies. Of the randomized controlled trials, many were limited by sample sizes of 15 individuals or less per group, making main effects difficult to detect. Thus, with caution, the literature suggests that among treatment seeking OA, treatment, whether age-specific or mixed-age, generally works yielding rates of abstinence comparable to general populations and younger cohorts. It also appears that with greater treatment exposure (higher dosage), regardless of level of care, OA do better. Finally, based on only two studies, age-specific treatment appears to potentiate treatment effects for OA. Like younger adults, OA appear to have a heterogeneous response to treatments, and preliminary evidence suggests a possibility of treatment matching for OA.

Conclusions

Expansion of research on SAT for OA is urgently needed for maximum effectiveness and efficiency of the healthcare system serving these individuals. Future research needs to include laboratory and community based randomized controlled trials with high internal validity of previously vetted evidenced-based practices, including Motivational Interviewing, cognitive behavioral therapy, and medications such as naltrexone, to determine the best fit for OA.

Supporting the education goals of post-9/11 veterans with self-reported PTSD symptoms: a needs assessment

PURPOSE

The influx of young adult veterans with mental health challenges from recent wars combined with newly expanded veteran education benefits has highlighted the need for a supported education service within the Veterans Administration. However, it is unknown how such a service should be designed to best respond to these needs. This study undertook a qualitative needs assessment for education supports among veterans with post-9/11 service with self-reported PTSD symptoms.

METHODS

Focus groups were held with 31 veterans, 54% of whom were under age 30. Transcripts were analyzed and interpreted using a thematic approach and a Participatory Action Research team.

RESULTS

Findings indicate a need for age relevant services that assist with: education planning and access, counseling for the G.I. Bill, accommodations for PTSD symptoms, community and family re-integration, and outreach and support.

CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

The veterans recommended that supported education be integrated with the delivery of mental health services, that services have varied intensity, and there be linkages between colleges and the Veterans Health Administration.

Prevalence and Impact of Substance Use among Emerging Adults with Serious Mental Health Conditions

TOPIC

This critical review of the literature integrates findings across varied literatures and identifies areas for continued study on the prevalence, correlates, and impact of substance use (alcohol and illicit drugs) on social role functioning among emerging adults with serious mental health conditions.

PURPOSE

This population is of interest because of high comorbidity rates between substance use and serious mental health conditions and the added difficulties posed by their co-occurrence during the transition to adulthood. This critical review presents the epidemiology of substance use in emerging adults with serious mental health conditions compared to emerging adults without these conditions, as well as what is known about predictors and consequences of substance use in this population.

SOURCES USED

PsychINFO and PubMed along with relevant published literature.

RESULTS

This review summarizes what is known about the impact of these co-occurring problems on the transition of emerging adults from school and training environments to adult work roles. Though this group presents with unique challenges, few programs have been developed to address their specific needs. This paper synthesizes what is known empirically about approaches with this population, discussing those that might be useful for emerging adults with comorbid serious mental health conditions and substance use problems, particularly in supporting their educational and vocational development.

CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

Emerging adults with co-occurring serious mental health conditions and substance use problems are underserved by current mental health systems. Recommendations focus on how to promote mental health and social role functioning through comprehensive intervention programs that provide continuity of care through the transition to adulthood.

Interaction effects of age and contingency management treatments in cocaine-dependent outpatients

As the American population ages, older adults are accounting for a larger percentage of the drug-abusing population, but little attention has been given to this age group especially in regards to evaluating responsivity to different treatment modalities. Contingency management (CM) is a highly effective behavioral treatment that provides positive tangible reinforcers for objective evidence of behavior change. The purpose of this study was to examine main and interactive effects of age on outcomes in cocaine-dependent patients receiving CM with standard care (SC) or SC alone. Patients (N = 393) participating in 1 of 3 randomized trials of CM for cocaine dependence were divided into young, middle, and older age cohorts. Baseline characteristics and outcomes were compared across the age groups. The oldest age group had more medical problems than the youngest and middle age groups but had fewer legal difficulties and psychiatric symptoms. The oldest age group remained in treatment significantly longer than the other age groups, regardless of the type of treatment received. Although all age groups benefited from CM in terms of retention and longest duration of abstinence achieved, a significant age by treatment interaction effect emerged, with the older cohort improving relatively less from CM than the younger age groups. These findings demonstrate that age may play a role in moderating intervention outcomes, and tailoring CM to the needs of older and middle-aged substance abusers may be important for improving outcomes in this growing population.

Alcohol use among older adults in the National Epidemiologic Survey on Alcohol and Related Conditions: a latent class analysis

OBJECTIVE

We examined latent classes of alcohol use among current drinkers ages 60 and older and explored risk factors associated with class.

METHOD

We used a subsample of older current drinkers (> or =60 years; n = 4,646) from the National Epidemiologic Survey on Alcohol and Related Conditions. Employing alcohol consumption and diagnostic indicators, latent class analysis was used to identify classes. We analyzed the associations between class membership and sociodemographic, psychiatric, health, and mental health variables using multinomial and linear regression.

RESULTS

Latent class analysis identified three latent classes. Individuals in the low-risk drinker class (89.17%) displayed low endorsement of heavy episodic use, at-risk consumption, and alcohol abuse/dependence criteria. Individuals in the moderate-risk drinker class (9.65%) were more likely to exceed consumption guidelines, and those in the high-risk drinker class (1.17%) displayed high probabilities of both Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV), criteria and risky alcohol consumption items. Female gender, older age, and African-American race were associated with decreased risk of being a moderate-risk drinker. Being the adult child of an alcoholic, being a previous smoker, and being a current smoker were associated with increased risk. Female gender, older age, and college education were associated with decreased odds of being a high-risk drinker. having major depression, being the child of an alcoholic, and being a current smoker were associated with increased odds of being a high-risk drinker. Individuals classified in the high-risk drinker class had significantly lower self-rated mental and physical health than low-risk drinkers.

CONCLUSIONS

A subpopulation of older drinkers may exceed consumption guidelines without DSM-defined alcohol-related problems. However, for some older drinkers, risky alcohol use is part of a larger pattern of health risks including current smoking, major depression, and alcohol abuse/dependence history.

Changing profile of abused substances by older persons entering treatment

This study evaluated whether there were increasing admissions for illicit drug abuse treatment among older persons from 1992 to 2005 in the United States and describes the characteristics, number, and type of substances most commonly abused in this population over this 14-year period. Analyses used public data files from the Treatment Episode Data Set, which tracks federally and state funded substance abuse treatment admissions. From 1992 to 2005, admissions for illicit drug abuse increased significantly; in 2005, 61% of admissions age 50 to 54 years old and 45% of admissions age 55 years and older reported some type of illicit drug abuse, most commonly heroin or cocaine abuse. Criminal justice referrals for drug abuse admissions have increased over time and daily substance use remains high. Efforts to determine best practices for prevention, identification, and treatment of illicit drug abuse in older persons are indicated.

Patient predictors of alcohol treatment outcome: a systematic review

Patient characteristics as predictors of alcohol use disorder treatment outcome were examined on three levels, identifying whether or not variables were significant predictors of drinking-related outcome in univariate analysis, in multivariate analysis, and in multivariate analyses limited to studies including several "key predictors." Also, a model was developed to predict total percentage of variance in treatment outcome accounted for in each study using each of the key predictors and a range of methodological factors. The most consistent univariate predictors were baseline alcohol consumption, dependence severity, employment, gender, psychopathology rating, treatment history, neuropsychological functioning, alcohol-related self-efficacy, motivation, socioeconomic status/income, treatment goal, and religion. When these key predictors were combined into multivariate analyses, baseline alcohol consumption and gender showed substantial reductions in predictive consistency whereas the remaining variables were not greatly affected. The most consistent predictors overall were dependence severity, psychopathology ratings, alcohol-related self-efficacy, motivation, and treatment goal. The two predictor variables most associated with greater variance accounted for in predictive models, when controlling for broader methodological variables, were baseline alcohol consumption and dependence severity. Few predictor variables were examined in more than a third of studies reviewed, and few variables were found to be significant predictors in a clear majority of studies. However, a subset of variables was identified, which collectively could be considered to represent a consistent set of predictors. Too few studies controlled for other important predictor variables. Attempts to synthesize findings were often hampered by lack of agreement of the best measure for predictor variables.

Substance abuse

Alcohol abuse poses special risks for increased morbidity and mortality among older adults, contributing to the heightened use of medical resources and the related increase in medical costs. Although the prevalance of alcohol use disorders in the older adults is generally less than that found in younger groups, it is expected to increase with the aging of the "baby-boom" generation. In spite of this, little attention has focused on developing, and evaluating the efficacy of, treatment programs for older adults with alcohol related disorders. This article discusses the availability of effective treatment strategies for older alcohol abusers and reviews the epidemiological and outcomes research literatures related to alcohol abuse and older adults. The few empirical studies that examine outcomes associated with the treatment of older substance abusers reveal positive outcomes, especially when "age-specific," cognitive-behavioral, and less confrontational treatment approaches are employed.

Alcohol use among older adults

Alcohol use problems among older adults have been called the "invisible epidemic." As the population of older adults continues to grow, there is an increased need to reexamine alcohol use in this population. The authors provide an overview on alcohol use in the over-60 age group. The main areas of focus included research on the prevalence of drinking in that population, as well as comments on the best practices in assessment and psychological treatment. Several screening assessments have been recommended for use with older adults, such as the CAGE questionnaire, Michigan Alcohol Screening Test-Geriatric version, Alcohol-Related Problems Survey, and the Alcohol Use Disorders Identification Test. The authors note age-appropriate psychological treatment interventions that include brief interventions, family interventions, motivational counseling, and cognitive behavioral therapies. Barriers to assessment and treatment are also discussed.

Five-year alcohol and drug treatment outcomes of older adults versus middle-aged and younger adults in a managed care program

AIMS

This study compared 5-year treatment outcomes of older adults to those of middle-aged and younger adults in a large managed care chemical dependency program. We examined age group differences in individual, treatment and extra-treatment factors, which may influence long-term outcome.

DESIGN

Seventy-seven per cent of original study participants completed a telephone interview 5 years after out-patient chemical dependency treatment at Kaiser Permanente. This sample (N = 925) included 65 patients aged 55-77, 296 patients aged 40-54 and 564 patients aged 18-39 (age at baseline).

MEASUREMENTS

Measures at follow-up included alcohol and drug use, Addiction Severity Index (ASI), Alcoholics Anonymous Affiliation Scale, social resource and self-reported health questions. Mortality data were obtained from contact with family members of patients as well as automated health plan records.

FINDINGS

Older adults were less likely to be drug-dependent at baseline than younger and middle-aged adults, and had longer retention in treatment than younger adults. At 5 years, older adults were less likely than younger adults to have close family or friends who encouraged alcohol or drug use. Fifty-two per cent of older adults reported total abstinence from alcohol and drugs in the previous 30 days versus 40% of younger adults. Older women had higher 30-day abstinence than older men or younger women. Among participants dependent only on alcohol, there were no significant age differences in 30-day abstinence. In logistic regression analysis, age group was not significant. Variables associated with greater age that independently predicted 30-day abstinence in the logistic regression model included longer retention in treatment and having no close family or friends who encouraged alcohol or drug use at 5 years; female gender was also significant.

CONCLUSIONS

Results indicate that older adults have favorable long-term outcome following treatment relative to younger adults, but these differences may be accounted for by variables associated with age such as type of substance dependence, treatment retention, social networks and gender. Age differences in these characteristics inform intervention strategies to support long-term recovery of older adults and provide direction for investigation of how age affects outcome.

Diagnosis and treatment of alcohol dependence in older alcoholics

Treatment of alcohol dependence among older alcoholic patients should be multidimensional to address as many potential relapse factors as possible. As the literature suggests, alcohol-related disorders often are under diagnosed and under treated. More efforts are needed to identify and improve diagnosis of these disorders in older alcoholic patients. For better outcomes, age-specific programs should be implemented. Furthermore, when treating elderly patients, basic therapeutic principles like respect for privacy and a respectful attitude should be adopted. Adequate medical, pharmacologic, and psychiatric treatment should be provided when appropriate. Medication to reduce cravings should be considered in patients without contraindications to its use. Participation in individual, group, and family therapy and attendance at self-help group meetings such as AA should be encouraged (Table 8). Despite the lack of empiric testing to validate these recommendations in an elderly population, clinical experience suggests that adherence to these recommendations will benefit elderly patients just as it has the general adult population. Research is necessary to explore the benefits of alcohol treatments in elderly patients. Until then, adherence to these recommendations should be the best available approach.

Referral paths, patient profiles and treatment adherence of older alcoholic men

We sought factors affecting completion by older men of 1-year outpatient treatment for alcohol dependence. We retrospectively studied clinical datasets of 110 men, age > or =55 years, consecutively admitted over 4 years, examining the association of 18 referral, treatment and patient variables with completion of treatment. We found that referral source was the most significant correlate of completion. Legal and self/family referrals were far more likely to complete treatment than patients referred by health or social services. Referral groups had distinctive profiles. Legal referrals were the healthiest. Self/family referrals were most likely to be married, to have had prior alcoholism treatment (a factor also associated with treatment completion), and to suffer currently from depression. Health/social services referrals showed the highest levels of psychosocial and physical dysfunction. Referral pathways deserve special consideration by programs treating older alcoholics. Special strategies for engaging dysfunctional older patients in alcoholism treatment are discussed.

Older and younger patients with substance use disorders: outpatient mental health service use and functioning over a 12-month interval

This observational study compared a nationwide sample of older patients with substance use disorders (n = 3,598; age > 55) with a demographically and diagnostically matched sample of younger patients on initial functioning, subsequent outpatient mental health service use, and 12-month follow-up outcomes. Older patents were initially functioning a well as or better than younger patients according to substance use, psychiatric, family, and legal criteria. The groups received comparable amounts of outpatient mental health care. At a 12-month follow-up, older patients generally had better substance use and functioning outcomes than did younger patients. The findings suggest that older patients with substance use disorders are keeping pace with demographically and diagnostically comparable younger patients in obtaining specialized outpatient mental health services and that they have positive treatment prognoses.

Outcomes at 1 and 5 years for older patients with alcohol use disorders

Older patients with alcohol use disorders who had gone through residential treatment were compared with matched groups of young and middle-aged patients (N = 432 in each age group) on their 1- and 5-year outcomes, use of continuing care services, and outcome predictors. Older patients had better outcomes than did young and middle-aged patients but had comparable levels of continuing substance abuse care and 12-step self-help group involvement. Similar factors predicted outcomes across the age groups. Longer duration of continuing substance abuse care and greater self-help group involvement were related to better outcomes, as were patients' attitudes and coping strategies at program discharge. The findings indicate that older patients with alcohol use disorders respond to age-integrated substance abuse treatment programs at least as well as do younger patients and are equally involved in formal and informal continuing substance abuse care.

Relapse prevention and maintaining abstinence in older adults with alcohol-use disorders

Although older adults are sometimes believed to have the lowest rates of alcohol abuse as an age cohort, the prevalence of alcohol use and abuse in this group is clearly underestimated. The under-diagnosis of alcohol abuse is due, in part, to the facts that the effects of alcohol use among older adults tend to be less clearly visible than among other age groups and that older adults are less likely to seek treatment than younger age groups. An additional challenge to diagnosis may be a lack of previous alcohol abuse by the patient, as approximately one-third of older adults with alcohol-use problems first develop their drinking problem after the age of 60 years. With a demographic shift that is expected to increase the number of older adults with alcohol problems, the awareness and understanding of this problem becomes increasingly important. Under-diagnosis of problem drinking in older adults is particularly unfortunate because the risks associated with alcohol abuse and relapse for the elderly are significant. Relapse, or the return to drinking following abstinence, may follow situations that are of particularly high risk for older adults. These include situations related to anxiety, interpersonal conflict, depression, loneliness, loss or social isolation. By helping patients to monitor these high-risk situations, to identify strategies that have been successful in promoting abstinence in the past, and to become engaged in treatment, relapse may be avoided and abstinence maintained. Treatments such as cognitive-behavioural therapy, group and family therapies and self-help groups are just as effective for older adults as they are for other age groups. In fact, group and family therapies and self-help groups may be of particular benefit to older adults because of the emphasis on social support. Medicinal adjuncts are also equally effective in the elderly, but strict compliance and careful monitoring of adverse effects are especially important in patients who take multiple medications. Because of their benign adverse effect profiles, naltrexone and acamprosate are particularly good pharmacological agents for relapse prevention in older adults.

Prognosis of older patients in mixed-age alcoholism treatment programs

Older patients were compared with matched groups of younger and middle-aged patients in inpatient alcohol treatment programs (N=432 in each age group). Compared with other patients, older patients had poorer physical health and lower cognitive status at treatment entry, but they were drinking less and reported fewer drinking-related problems, fewer psychological symptoms, more social support, more adaptive coping, and fewer barriers to abstinence. Older patients had positive views of the programs and, except for less family therapy and problem-focused counseling, received comparable treatment to that received by other patients. At discharge, older patients showed significant change in most areas targeted for treatment. Better initial status was the strongest predictor of better discharge functioning. Patients with higher cognitive functioning and stronger treatment motivation and those who experienced more interpersonal support and who received more specialized treatment services showed better-than-expected improvement. The age groups showed similar outcomes, prognostic factors, and response to different treatment orientations.

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.

Sex-exclusive quantitative trait loci influences in alcohol-related phenotypes

During the past half century, researchers have identified and examined sex differences in alcohol-related phenotypes, focusing more recently on understanding of the mechanisms underlying these differences. In general, the genetic contributions influencing these differences are not consistent with an interpretation of sex linkage and must, therefore, reflect some form of sex limitation in which allelic differences at particular autosomal loci have different consequences in males and females. Significant sex differences in measures of alcohol consumption in mice have been demonstrated in previous work in our laboratory. To investigate these differences further, we explore the limiting case of sex-exclusive effects using data from (BXD) recombinant inbred (RI) strains of mice and from an intercross derived from the same progenitors, C57BL/6J (B) and DBA/2J (D). By the use of two statistical approaches (examination of residual scores as a sex-exclusive phenotypic value for the RI strains and multivariate regression on sex and genotype in the F(2)) we have identified and confirmed female-exclusive markers for alcohol acceptance on chromosomes 9 and 12 and one marker for alcohol preference on chromosome 2. Am. J. Med. Genet. (Neuropsychiatr. Genet.) 88:647-652, 1999.

Program characteristics and readmission among older substance abuse patients: comparisons with middle-aged and younger patients

Older substance abuse patients were compared to middle-aged and younger patients before, during, and after an index episode of inpatient care in 1 of 88 substance abuse treatment programs. Associations between program characteristics and readmission rates adjusted for key differences in the types of patients in different programs varied by age group. Among older patients, more structured program policies, more flexible rules about discharge, more comprehensive assessment, and more outpatient mental health aftercare were associated with lower casemix-adjusted readmission rates. More intensive treatment was associated with higher-than-predicted readmission. By contrast, among younger patients, more family involvement in assessment and treatment, community consultation, and treatment emphasizing the development of social and work skills were associated with lower casemix-adjusted readmission rates. The findings suggest that intensive, directed treatment may be more effective for younger substance abuse patients, whereas a more supportive treatment regimen in a well-organized program and prompt outpatient aftercare may be especially helpful for older patients.

Alcohol treatment outcome methodology: state of the art 1989-1993

This article reviews the 61 alcohol treatment outcome studies published from 1989-1993 with respect to methodology. Although better assessment of subjects' pretreatment characteristics was noted, a minority of studies met even the basic requirements of experimental studies. Further, some reversals of methodological progress were observed in several areas, particularly in collecting outcome data from multiple sources. It is suggested that funding agencies and journal editors require that submissions meet minimum standards for adequate outcome evaluation.
