Prevention of alcohol-related deaths in middle-aged heavy drinkers

Does Advice Based on Biomarkers of Liver Injury or Non-Invasive Tests of Liver Fibrosis Impact High-Risk Drinking Behaviour: A Systematic Review With Meta-analysis

BACKGROUND AND AIMS

Alcohol dependence affects over 240 million people worldwide and attributed to 3 million deaths annually. Early identification and intervention are key to prevent harm. We aim to systematically review literature on the effectiveness of adding advice based on biomarkers of liver injury or non-invasive tests of liver fibrosis (intervention-based advice) to prevent alcohol misuse.

METHODS

Electronic search was conducted on Ovid Medline, PubMed, EMBASE, Psychinfo and CINAHL for articles published up to end of February 2020. Additionally, we searched study citations, Scopus, Ethos and Clinical trials. The primary outcome measure was changed in self-reported alcohol consumption analysed by random-effects meta-analysis. Secondary outcomes included change to liver blood markers and alcohol-related health outcomes.

RESULTS

Fourteen randomized controlled trials (RCTs) and two observational studies comprising n = 3763 participants were included. Meta-analyses showed a greater reduction in alcohol consumption and liver biomarkers for the intervention compared to control group: mean difference for weekly alcohol intake was -74.4 g/week (95% confidence interval (CI) -126.1, -22.6, P = 0.005) and mean difference for gamma-glutamyl transferase (GGT) -19.7 IU/l (95% CI -33.1, -6.4, P = 0.004). There was a higher incidence of alcohol-attributed mortality, number of days spent in the hospital, physician visits and sickness absence in the non-intervention group. The quality of the included studies was moderate for RCTs and high for observational studies.

CONCLUSIONS

The review confirmed a significant association between the addition of intervention-based advice in routine care to the reduction of harmful alcohol consumption, GGT and alcohol-related mortality. The findings support the inclusion of this type of advice in routine alcohol care.

Effects of automated smartphone mobile recovery support and telephone continuing care in the treatment of alcohol use disorder: study protocol for a randomized controlled trial

Background

New smartphone communication technology provides a novel way to provide personalized continuing care support following alcohol treatment. One such system is the Addiction version of the Comprehensive Health Enhancement Support System (A-CHESS), which provides a range of automated functions that support patients. A-CHESS improved drinking outcomes over standard continuing care when provided to patients leaving inpatient treatment. Effective continuing care can also be delivered via telephone calls with a counselor. Telephone Monitoring and Counseling (TMC) has demonstrated efficacy in two randomized trials with alcohol-dependent patients. A-CHESS and TMC have complementary strengths. A-CHESS provides automated 24/7 recovery support services and frequent assessment of symptoms and status, but does not involve regular contact with a counselor. TMC provides regular and sustained contact with the same counselor, but no ongoing support between calls. The future of continuing care for alcohol use disorders is likely to involve automated mobile technology and counselor contact, but little is known about how best to integrate these services.

Methods/Design

To address this question, the study will feature a 2 × 2 design (A-CHESS for 12 months [yes/no] × TMC for 12 months [yes/no]), in which 280 alcohol-dependent patients in intensive outpatient programs (IOPs) will be randomized to one of the four conditions and followed for 18 months. We will determine whether adding TMC to A-CHESS produces fewer heavy drinking days than TMC or A-CHESS alone and test for TMC and A-CHESS main effects. We will determine the costs of each of the four conditions and the incremental cost-effectiveness of the three active conditions. Analyses will also examine secondary outcomes, including a biological measure of alcohol use, and hypothesized moderation and mediation effects.

Discussion

The results of the study will yield important information on improving patient alcohol use outcomes by integrating mobile automated recovery support and counselor contact.

Patient-centered primary care for adults at high risk for AUDs: the Choosing Healthier Drinking Options In primary CarE (CHOICE) trial

BACKGROUND

Most patients with alcohol use disorders (AUDs) never receive alcohol treatment, and experts have recommended management of AUDs in primary care. The Choosing Healthier Drinking Options In primary CarE (CHOICE) trial was a randomized controlled effectiveness trial of a novel intervention for primary care patients at high risk for AUDs. This report describes the conceptual and scientific foundation of the CHOICE model of care, critical elements of the CHOICE trial design consistent with the Template for Intervention Description and Replication (TIDieR), results of recruitment, and baseline characteristics of the enrolled sample.

METHODS

The CHOICE intervention is a multi-contact, extended counseling intervention, based on the Chronic Care Model, shared decision-making, motivational interviewing, and evidence-based options for managing AUDs, designed to be practical in primary care. Outpatients who received care at 3 Veterans Affairs primary care sites in the Pacific Northwest and reported frequent heavy drinking (≥4 drinks/day for women; ≥5 for men) were recruited (2011-2014) into a trial in which half of the participants would be offered additional alcohol-related care from a nurse. CHOICE nurses offered 12 months of patient-centered care, including proactive outreach and engagement, repeated brief motivational interventions, monitoring with and without alcohol biomarkers, medications for AUDs, and/or specialty alcohol treatment as appropriate and per patient preference. A CHOICE nurse practitioner was available to prescribe medications for AUDs.

RESULTS

A total of 304 patients consented to participate in the CHOICE trial. Among consenting participants, 90% were men, the mean age was 51 (range 22-75), and most met DSM-IV criteria for alcohol abuse (14%) or dependence (59%). Many participants also screened positive for tobacco use (44%), depression (45%), anxiety disorders (30-41%) and non-tobacco drug use disorders (19%). At baseline, participants had a median AUDIT score of 18 [Interquartile range (IQR) 14-24] and a median readiness to change drinking score of 5 (IQR 2.75-6.25) on a 1-10 Likert scale.

CONCLUSION

The CHOICE trial tested a patient-centered intervention for AUDs and recruited primary care patients at high risk for AUDs, with a spectrum of severity, co-morbidity, and readiness to change drinking. Trial registration The trial is registered at clinicaltrial.gov (NCT01400581).

Socioeconomic differences in alcohol-attributable mortality compared with all-cause mortality: a systematic review and meta-analysis

BACKGROUND

Factors underlying socioeconomic inequalities in mortality are not well understood. This study contributes to our understanding of potential pathways to result in socioeconomic inequalities, by examining alcohol consumption as one potential explanation via comparing socioeconomic inequalities in alcohol-attributable mortality and all-cause mortality.

METHODS

Web of Science, MEDLINE, PsycINFO and ETOH were searched systematically from their inception to second week of February 2013 for articles reporting alcohol-attributable mortality by socioeconomic status, operationalized by using information on education, occupation, employment status or income. The sex-specific ratios of relative risks (RRRs) of alcohol-attributable mortality to all-cause mortality were pooled for different operationalizations of socioeconomic status using inverse-variance weighted random effects models. These RRRs were then combined to a single estimate.

RESULTS

We identified 15 unique papers suitable for a meta-analysis; capturing about 133 million people, 3 741 334 deaths from all causes and 167 652 alcohol-attributable deaths. The overall RRRs amounted to RRR = 1.78 (95% confidence interval (CI) 1.43 to 2.22) and RRR = 1.66 (95% CI 1.20 to 2.31), for women and men, respectively. In other words: lower socioeconomic status leads to 1.5-2-fold higher mortality for alcohol-attributable causes compared with all causes.

CONCLUSIONS

Alcohol was identified as a factor underlying higher mortality risks in more disadvantaged populations. All alcohol-attributable mortality is in principle avoidable, and future alcohol policies must take into consideration any differential effect on socioeconomic groups.

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.

Can screening and brief intervention lead to population-level reductions in alcohol-related harm?

A distinction is made between the clinical and public health justifications for screening and brief intervention (SBI) against hazardous and harmful alcohol consumption. Early claims for a public health benefit of SBI derived from research on general medical practitioners’ (GPs’) advice on smoking cessation, but these claims have not been realized, mainly because GPs have not incorporated SBI into their routine practice. A recent modeling exercise estimated that, if all GPs in England screened every patient at their next consultation, 96% of the general population would be screened over 10 years, with 70-79% of excessive drinkers receiving brief interventions (BI); assuming a 10% success rate, this would probably amount to a population-level effect of SBI. Thus, a public health benefit for SBI presupposes widespread screening; but recent government policy in England favors targeted versus universal screening, and in Scotland screening is based on new registrations and clinical presentation. A recent proposal for a national screening program was rejected by the UK National Health Service’s National Screening Committee because 1) there was no good evidence that SBI led to reductions in mortality or morbidity, and 2) a safe, simple, precise, and validated screening test was not available. Even in countries like Sweden and Finland, where expensive national programs to disseminate SBI have been implemented, only a minority of the population has been asked about drinking during health-care visits, and a minority of excessive drinkers has been advised to cut down. Although there has been research on the relationship between treatment for alcohol problems and population-level effects, there has been no such research for SBI, nor have there been experimental investigations of its relationship with population-level measures of alcohol-related harm. These are strongly recommended. In this article, conditions that would allow a population-level effect of SBI to occur are reviewed, including their political acceptability. It is tentatively concluded that widespread dissemination of SBI, without the implementation of alcohol control measures, might have indirect influences on levels of consumption and harm but would be unlikely on its own to result in public health benefits. However, if and when alcohol control measures were introduced, SBI would still have an important role in the battle against alcohol-related harm.

Developing, evaluating and implementing alcohol brief interventions in Europe

ISSUES

This article traces the history of research on the development, evaluation and implementation of alcohol brief intervention (BI) in Europe.

APPROACH

Narrative and historical review.

KEY FINDINGS

BI originated in Europe and, following a definition of opportunistic BI, early pioneering studies are summarised. The role of European scientists in the series of studies making up the WHO Collaborative Project on Detection and Management of Alcohol-related Problems in Primary Health Care (1982-2006) is then described, followed by a short account of a current EU-funded project (Primary Health European Project on Alcohol) with the aim of achieving a widespread, routine and enduring implementation of BI in EU member states. In addition to involvement in these two major projects, a great deal of research on BI has been carried out in a range of European countries and some of this research is noted.

IMPLICATIONS

Several European governments are now taking the rolling out of BI in routine services very seriously as a policy measure. There is no necessary conflict between widely available BI and alcohol control measures.

CONCLUSION

While much remains to be done regarding practical implementation, the mood of those interested in the promotion of BI as a means of reducing alcohol-related harm, in Europe as elsewhere, is cautiously optimistic.

Reducing alcohol related harm experienced by Indigenous Australians: identifying opportunities for Indigenous primary health care services

OBJECTIVE

Identify key issues and opportunities relating to the dissemination of cost-effective interventions for alcohol in Indigenous-specific settings.

METHODS

Update previous reviews of the Indigenous alcohol literature, particularly in relation to intervention and dissemination studies aimed at identifying and integrating into routine clinical care those strategies that are most cost-effective in reducing alcohol-related harm.

RESULTS

The harmful use of alcohol has been identified as a major public health issue, which has a disproportionately high negative impact on Indigenous Australians. While the disproportionately high burden of harm borne by Indigenous Australian communities is well documented in descriptive studies, attempts to redress this imbalance through well controlled intervention and dissemination studies appear to have been inadequate to date. There is compelling evidence from the non-Indigenous community that brief intervention is an effective treatment for harmful alcohol use, compared to the relatively lower levels of evidence for primary and tertiary level interventions. The effectiveness of brief intervention for alcohol in Indigenous Australian communities should, therefore, be examined.

CONCLUSIONS AND IMPLICATIONS

An opportunity exists to implement brief intervention into Indigenous primary health care settings, as an evidence-based strategy using established resources. There is the possibility that such Indigenous-specific health services research will lead the dissemination field in demonstrating how the implementation process can be successfully tailored to specific and defined clinical settings.

Physical health and drinking among medical inpatients with unhealthy alcohol use: a prospective study

OBJECTIVE

Unhealthy alcohol use is common in medical inpatients, and hospitalization has been hypothesized to serve as a "teachable moment" that could motivate patients to decrease drinking, but studies of hospital-based brief interventions have often not found decreases. Evaluating associations between physical health and subsequent drinking among medical inpatients with unhealthy alcohol use could inform refinement of hospital-based brief interventions by identifying an important foundation on which to build them. We tested associations between poor physical health and drinking after hospitalization and whether associations varied by alcohol dependence status and readiness to change.

METHODS

Participants were medical inpatients who screened positive for unhealthy alcohol use and consented to participate in a randomized trial of brief intervention (n = 341). Five measures of physical health were independent variables. Outcomes were abstinence and the number of heavy drinking days (HDDs) reported in the 30 days prior to interviews 3 months after hospitalization. Separate regression models were fit to evaluate each independent variable controlling for age, gender, randomization group, and baseline alcohol use. Interactions between each independent variable and alcohol dependence and readiness to change were tested. Stratified models were fit when significant interactions were identified.

RESULTS

Among all participants, measures of physical health were not significantly associated with either abstinence or number of HDDs at 3 months. Having an alcohol-attributable principal admitting diagnosis was significantly associated with fewer HDDs in patients who were nondependent [adjusted incidence rate ratio (aIRR) 0.10, 95% CI 0.03-0.32] or who had low alcohol problem perception (aIRR 0.36, 95% CI 0.13-0.99) at hospital admission. No significant association between alcohol-attributable principal admitting diagnosis and number of HDDs was identified for participants with alcohol dependence or high problem perception.

CONCLUSIONS

Among medical inpatients with nondependent unhealthy alcohol use and those who do not view their drinking as problematic, alcohol-attributable illness may catalyze decreased drinking. Brief interventions that highlight alcohol-related illness might be more successful.

Results from two randomized clinical trials evaluating the impact of quarterly recovery management checkups with adult chronic substance users

AIMS

Post-discharge monitoring and early reintervention have become standard practice when managing numerous chronic conditions. These two experiments tested the effectiveness of recovery management checkup (RMC) protocols for adult chronic substance users.

INTERVENTION

RMC included quarterly monitoring; motivational interviewing to provide personalized feedback and to resolve ambivalence about substance use; treatment linkage, engagement and retention protocols to increase the amount of treatment received.

PARTICIPANTS AND SETTING

Recruited from sequential addiction treatment admissions, participants in the two experiments were, on average, 36 and 38 years of age, mainly female (59% versus 46%), African American (85% versus 80%) and met past-year criteria for dependence (87% versus 76%).

DESIGN

Participants in both experiments were assigned randomly to the RMC or control condition and interviewed quarterly for 2 years.

MEASUREMENT

The Global Appraisal of Individual Needs (GAIN) was the main assessment instrument.

FINDINGS

RMC participant outcomes were better than control participants in both experiments. Effect sizes were larger in the second experiment in terms of reducing days to readmission (Cohen's d = 0.41 versus d = 0.22), successive quarters in the community using substances (d = -0.32 versus -0.19), past-month symptoms of abuse/dependence (d = -0.23 versus -0.02) and increasing the days of abstinence over 2 years (d = +0.29 versus 0.04).

CONCLUSION

RMC, which provided ongoing monitoring and linkage, is feasible to conduct and is effective for adults with chronic substance dependence.

Continuing care research: what we have learned and where we are going

In the field of addiction treatment, the term continuing care has been used to indicate the stage of treatment that follows an initial episode of more intensive care. This article reviews controlled studies of continuing care conducted over the prior 20 years. The results indicate that continuing care interventions were more likely to produce positive treatment effects when they had a longer planned duration, made more active efforts to deliver treatment to patients, and were studied more recently. However, there was considerable variability in patient response and room for improvements in participation rates and effectiveness. It is possible that the effectiveness of continuing care interventions could be further improved by the use of adaptive algorithms, which adjust treatment over time based on changes in patients' symptoms and status. The use of alternative service delivery methods and care settings may also lead to greater engagement and retention in continuing care, particularly among the large numbers of individuals who do not want traditional, clinic-based specialty care.

Primary care intervention to reduce alcohol misuse ranking its health impact and cost effectiveness

BACKGROUND

The U.S. Preventive Services Task Force (USPSTF) has recommended screening and behavioral counseling interventions in primary care to reduce alcohol misuse. This study was designed to develop a standardized rating for the clinically preventable burden and cost effectiveness of complying with that recommendation that would allow comparisons across many recommended services.

METHODS

A systematic review of the literature from 1992 through 2004 to identify relevant randomized controlled trials and cost-effectiveness studies was completed in 2005. Clinically preventable burden (CPB) was calculated as the product of effectiveness times the alcohol-attributable fraction of both mortality and morbidity (measured in quality-adjusted life years or QALYs), for all relevant conditions. Cost effectiveness from both the societal perspective and the health-system perspective was estimated. These analyses were completed in 2006.

RESULTS

The calculated CPB was 176,000 QALYs saved over the lifetime of a birth cohort of 4,000,000, with a range in sensitivity analysis from -43% to +94% (primarily due to variation in estimates of effectiveness). Screening and brief counseling was cost-saving from the societal perspective and had a cost-effectiveness ratio of $1755/QALY saved from the health-system perspective. Sensitivity analysis indicates that from both perspectives the service is very cost effective and may be cost saving.

CONCLUSIONS

These results make alcohol screening and counseling one of the highest-ranking preventive services among the 25 effective services evaluated using standardized methods. Since current levels of delivery are the lowest of comparably ranked services, this service deserves special attention by clinicians and care delivery systems.

Screening and brief intervention enter their 5th decade

About 40 years since the first controlled study, screening and brief intervention (SBI) are being disseminated into practice. But many unanswered questions remain. Studies in this special issue address what we know and don't know about alcohol and drug SBI, cost-effectiveness, patient preferences, education for clinicians, quality performance measures, 'no-contact' SBI, predictors of behavior change, and methodological concerns with the SBI literature. The best evidence for efficacy of SBI is that it can lead to decreased consumption in primary care patients with non-dependent unhealthy alcohol use. But further research is needed on brief drug screening tools, efficacy of SBI for drugs, effectiveness in real world settings, integration of SBI for alcohol and drugs with other health behaviors, effects of SBI on alcohol and drug consequences, effects on dependence among those not seeking help, and on how to best disseminate the efficacious elements of SBI into practice.

Effectiveness of brief alcohol interventions in primary care populations

BACKGROUND

Many trials reported that brief interventions are effective in reducing excessive drinking. However, some trials have been criticised for being clinically unrepresentative and unable to inform clinical practice.

OBJECTIVES

To assess the effectiveness of brief intervention, delivered in general practice or based primary care, to reduce alcohol consumption

SEARCH STRATEGY

We searched the Cochrane Drug and Alcohol Group specialised register (February 2006), MEDLINE (1966 to February 2006), EMBASE (1980 to February 2006), CINAHL (1982 to February 2006), PsycINFO (1840 to February 2006), Science Citation Index (1970 to February 2006), Social Science Citation Index (1970 to February 2006), Alcohol and Alcohol Problems Science Database (1972 to 2003), reference lists of articles.

SELECTION CRITERIA

Randomised controlled trials, patients presenting to primary care not specifically for alcohol treatment; brief intervention of up to four sessions.

DATA COLLECTION AND ANALYSIS

Two authors independently abstracted data and assessed trial quality. Random effects meta-analyses, sub-group, sensitivity analyses, and meta-regression were conducted.

MAIN RESULTS

The meta-analysis included 21 RCTs (7,286 participants), showing that participants receiving brief intervention reduced their alcohol consumption compared to the control group (mean difference: -41 grams/week, 95% CI: -57 to -25), although there was substantial heterogeneity between trials (I2 = 52%). Sub-group analysis (8 studies, 2307 participants) confirmed the benefit of brief intervention in men (mean difference: -57 grams/week, 95% CI: -89 to -25, I2 = 56%), but not in women (mean difference: -10 grams/week, 95% CI: -48 to 29, I2 = 45%). Meta-regression showed a non-significant trend of an increased reduction in alcohol consumption of 1.1, 95%CI: -0.05 to 2.2 grams/week, p=0.06, for each extra minute of treatment exposure, but no relationship between the reduction in alcohol consumption and the efficacy score of the trial. Extended intervention when compared with brief intervention was associated with a non-significantly greater reduction in alcohol consumption (mean difference = -28, 95%CI: -62 to 6 grams/week, I2 = 0%)

AUTHORS' CONCLUSIONS

Brief interventions consistently produced reductions in alcohol consumption. When data were available by gender, the effect was clear in men at one year of follow up, but unproven in women. Longer duration of counselling probably has little additional effect. The lack of differences in outcomes between efficacy and effectiveness trials suggests that the current literature had clear relevance to routine primary care. Future trials should focus on women and on delineating the most effective components of interventions.

Risk of mortality during four years after substance detoxification in urban adults

The objective of this analysis was to assess the mortality rate and risk factors in adults, with substance dependence, who are not receiving primary medical care (PC). Date and cause of death were identified using the National Death Index data and death certificates for 470 adults without PC over a period of almost 4 years after detailed clinical assessment after detoxification. Factors associated with risk of mortality were determined using stepwise Cox proportional hazards models. Subjects were 76% male, 47% homeless, and 47% with chronic medical illness; 40% reported alcohol, 27% heroin, and 33% cocaine as substance of choice. Median age was 35. During a period of up to 4 years, 27 (6%) subjects died. Median age at death was 39. Causes included: poisoning by any substance (40.9% of deaths), trauma (13%), cardiovascular disease (13.6%), and exposure to cold (9.1%). The age adjusted mortality rate was 4.4 times that of the general population in the same city. Among these individuals without PC in a detoxification unit, risk factors associated with death were the following: drug of choice [heroin: hazard ratio (HR) 6.9 (95% confidence interval (CI) 1.6-31.1]; alcohol: HR 3.7 (95% CI 0.79-16.9) compared to cocaine); past suicide attempt (HR 2.1, 95% CI 0.96-4.5); persistent homelessness (HR 2.4, 95% CI 1.1-5.3); and history of any chronic medical illness (HR 2.1, 95% CI 0.93-4.7). Receipt of primary care was not significantly associated with death (HR 0.85, 95% CI 0.34-2.1). Risk of mortality is high in patients with addictions and risk factors identifiable when these patients seek help from the health care system (i.e., for detoxification) may help identify those at highest risk for whom interventions could be targeted.

Predictors of 16-Year Mortality Among Individuals Initiating Help-Seeking for an Alcoholic Use Disorder

BACKGROUND AND METHODS

We examined rates and predictors of mortality in individuals (47% women) who had just initiated help-seeking for their alcohol use disorders (AUDs) at the start of the study (n=628) and were followed for 16 years.

RESULTS

For both women and men, the observed-to-expected mortality ratio (1.4) was lower than rates found in samples of treated individuals with AUDs, suggesting that those initiating help-seeking careers have better chances of long-term survival. Of the individuals for whom cause of death was known, 68% died of alcohol-related causes. Men were more likely to die than were women. When gender was controlled, individuals who were older and unmarried and had more alcohol dependence symptoms at baseline were more likely to die over the 16-year period. When these baseline characteristics were controlled, better drinking outcomes at 1 year were associated with a lower likelihood of subsequent death. The combination of a shorter duration of inpatient/residential care and better drinking outcomes at 1 year was related to a lower probability of death, as was the combination of a longer duration of outpatient care or Alcoholics Anonymous attendance and better drinking outcomes at 1 year.

CONCLUSIONS

Efforts should be made to help providers identify individuals who are not responding positively to inpatient or residential treatment and intervene to motivate participation in continuing outpatient care and community 12-step self-help groups to reduce the likelihood of a chronic and fatal AUD course.

Does socio-economic status influence the acceptability of, attendance for, and outcome of, screening and brief interventions for alcohol misuse: a review

AIMS

To determine whether socio-economic status (SES) influences (i) willingness to participate in brief intervention (BI) research, (ii) attendance to receive BI once allocated, and (iii) treatment outcome.

METHODS

Systematic review of published, randomised controlled trials of BI for non-dependent alcohol misuse in primary health care settings.

RESULTS

Eighteen papers met inclusion criteria. There is evidence that once recruited, and following attendance for intervention, participants' SES does not influence treatment outcome. However, the effect of choosing to participate remains unclear, and the generalizability of results to the whole primary care population remains equivocal. Socio-economic status may influence willingness to participate in BI treatment research, and may influence attendance to receive such interventions where allocated.

CONCLUSION

Brief interventions should remain available to all non-dependent hazardous and harmful drinkers in primary care. However, fidelity to research design is suggested to allow for any participation effects to occur. Benefits of such an approach exist for both clinicians and patients. The characteristics of those who participate in BI trials, compared to those who do not, should be studied in detail. Socio-economic variables should be included as potentially important characteristics. The impact of BI on drinking style as well as consumption needs further attention.

[Alcoholism in the general hospital: 4 years mortality and hospitalization]

BACKGROUND AND OBJECTIVE

We aimed to analyze the mortality, and emergency room and hospital admissions in a sample of alcohol dependent patients during the four years following their identification in a general hospital.

PATIENTS AND METHOD

198 inpatients from a general hospital who where identified as alcohol dependent and referred during 1998 to the liaison-psychiatry service.

RESULTS

30.8% had died, at a mean age of 57.5 (11.3). Deaths had a direct relationship to the illness responsible for the initial admission to hospital. 42.6% of patients had previous admissions, and 74% had been previously attended at emergency room departments. During the 4 years of follow up, there were new hospital admissions (54.6%), emergency room visits (72.7%) and repeated liaison-psychiatry consultations (20%). Previous admissions to hospital predicted future admissions. Acceptance of alcohol treatment did not reduce the mortality rates. Mortality correlated with age, it was increased in patients with cognitive deficits and was reduced in those with psychiatric co-morbidity.

CONCLUSIONS

Late detection of alcohol dependence leads to pour outcomes both in the treatment of alcohol dependence and the concomitant somatic diseases. Early detection strategies of hazardous and harmful alcohol consumption should be implemented in hospital settings.

Is there a case for extended interventions for alcohol and drug use disorders?

AIMS

To determine whether there is evidence to support the implementation of extended interventions (i.e. longer than 6 months) for individuals with alcohol or other drug use disorders.

METHODS

Literature on extended behavioral and pharmacotherapy interventions was reviewed, along with findings from studies of extended monitoring and monitoring paired with adjunctive counseling. Studies were identified through database searches, citations in prior reviews and examinations of recent volumes of relevant journals. Key terms were defined, and a theoretical rationale was presented for extended treatment. Several adaptive treatment studies that made use of stepped care or continuation protocols were also described.

MEASUREMENTS

The primary outcomes that were considered were alcohol and drug use during the intervention and post-intervention follow-ups. Other outcomes were examined when they were included in the articles reviewed.

FINDINGS

Most of the studies in the review provided support for the effectiveness of extended interventions for alcohol and drug abusers, whether the extended care was delivered through face-to-face contact or via the telephone. These findings held across all types of interventions that were examined (e.g. behavioral treatment, pharmacotherapy and monitoring). However, only a few studies directly compared extended and standard length version of the same intervention. New developments in addiction treatment with implications for extended care models were also described and discussed.

CONCLUSIONS

The findings of the review indicate that maintaining therapeutic contact for extended periods of time with individuals with alcohol and other drug disorders appears to promote better long-term outcomes than 'treatment as usual', although more studies are needed that compare extended and standard versions of interventions. Achieving good compliance and successful disease management with extended interventions will probably require adaptive protocols in which the intensity of treatment can be adjusted up or down in response to changes in symptoms and functioning over time. Future directions in research on extended interventions were discussed.

Integrating care for patients with infectious, psychiatric, and substance use disorders: concepts and approaches

Patients with chronic viral infections such as HIV/AIDS or hepatitis C often have multiple co-existing problems such as psychiatric and addictive disorders, as well as social problems such as lack of housing, transportation and income that present challenging obstacles to successful management. Because services for these different problems are usually provided by different disciplines in varying locations, fragmentation of care can lead to treatment dropouts, lack of adherence, and poor outcomes. Integration strategies, ranging from simple efforts to improve communication and coordinate care to fully integrated multidisciplinary teams have been used to improve disease management. Although evidence for effectiveness is comprised primarily of observational studies of demonstration programmes, integration may be desirable on a pragmatic basis alone. Quality improvement strategies are attractive vehicles for implementing care integration and measuring its impact. Careful assessment of the problem to be solved and the development of targeted strategies will maximize chances of a successful outcome.

Association of alcohol and drug use disorders and completed suicide: an empirical review of cohort studies

BACKGROUND

This study updated and expanded upon Harris and Barraclough's empirical review [Harris, E.C., Barraclough, B., 1997. Suicide as an outcome for mental disorders. A meta-analysis, Br. J. Psychiatry 170, 205-228] of retrospective and prospective cohort studies of alcohol and drug use disorders and suicide.

METHOD

Studies presenting data on alcohol and drug use disorders and suicide originally identified by Harris and Barraclough were used in this study. To find additional studies, (1) the location of English language reports on MEDLINE (1994-2002) were identified with the search terms 'substance-disorders' with 'mortality' and 'follow-up', (2) read throughs were conducted of four prominent alcohol and drug specialty journals from 1966 through 2002, and (3) the reference sections of studies that met criteria were searched for additional reports. This strategy yielded 42 new studies meeting eligibility criteria.

RESULTS

The estimated standardized mortality ratios (SMR; 95% confidence interval) for suicide were as follows: alcohol use disorder (979; 95% CI 898-1065; p < 0.001), opioid use disorder (1351; 95% CI 1047-1715; p < 0.001), intravenous drug use (1373; 95% CI 1029-1796; p < 0.001), mixed drug use (1685; 95% CI 1473-1920; p < 0.001), heavy drinking (351; 95% CI 251-478; p < 0.001). SMR estimates stratified by sex were also calculated.

CONCLUSIONS

Additional studies on the association of suicide and mixed drug use, heavy drinking, and alcohol use disorders in women augmented the findings of Harris and Barraclough, along with a novel estimate for intravenous drug use, a byproduct of intensive research on HIV in the past decade. There is a large empirical literature on alcohol use disorders and suicide and a moderate literature on suicide and opioid use disorders and IV drug use. There remains limited prospective data on the association of suicide and other drug use disorders (e.g., cocaine, cannabis).

The effects on mortality of brief interventions for problem drinking: a meta-analysis

AIMS

Brief interventions for problem drinking may result in decreased mortality rates. Long-term follow-up studies of brief interventions do not produce a clear answer to the question as to whether these interventions reduce mortality or not.

METHODS

We conducted a meta-analysis of randomized studies comparing brief interventions with a control group, using the fixed-effects model. A systematic literature search produced four studies in which the mortality status of subjects was verified at follow-up. Six more studies reported some deaths at follow-up but did not verify mortality in death registers, and 22 further studies did not report the mortality status of the included subjects.

FINDINGS

The pooled relative risk (RR) of dying was 0.47 for the four studies with verified mortality rates (95% CI: 0.25, 0.89). The pooled RR of all 32 studies was comparable (RR = 0.57; 95% CI: 0.38, 0.84), as were the RRs of several other subsamples of studies. The prevented fraction was 0.33 in the studies with verified mortality rates.

CONCLUSIONS

Although the overall death rate was low in the population of problem drinkers, brief interventions do appear to reduce mortality.

Interventions for preventing injuries in problem drinkers

BACKGROUND

Alcohol consumption has been linked with injuries through motor vehicle crashes, falls, drowning, fires and burns, and violence. In the US, half of the estimated 100,000 deaths attributed to alcohol each year are due to intentional and unintentional injuries. The identification of effective interventions for the reduction of unintentional and intentional injuries due to problem drinking is, therefore, an important public health goal.

OBJECTIVES

To assess the effect of interventions for problem drinking on subsequent injury risk.

SEARCH STRATEGY

We searched 12 twelve computerized databases: MEDLINE (1966-8/96), EMBASE (1982-1/97), Cochrane Controlled Trials Register (1997, issue #1), PsycINFO (1967-1/97), CINAHL (1982-10/96), ERIC (1966-12/96), Dissertation Abstracts International (1861-11/96), IBSS (1961-1/97), ISTP (1982-1/97) and three specialized transportation databases, using terms for problem drinking combined with terms for controlled trials; bibliographies of relevant trials; and contact with authors and government agencies. The electronic and bibliographic searches were updated in May 2002.

SELECTION CRITERIA

Randomized controlled trials of interventions among participants with problem drinking, which are intended to reduce alcohol consumption or to prevent injuries or their antecedents, and which measured injury-related outcomes.

DATA COLLECTION AND ANALYSIS

Two authors extracted data on participants, interventions, follow-up, allocation concealment, and outcomes, and independently rated allocation concealment quality.

MAIN RESULTS

Of 23 eligible trials identified, 22 had been completed and 17 provided results for relevant outcomes. Completed trials of problem drinkers that compared interventions for problem drinking to no intervention reported reduced motor-vehicle crashes and related injuries, falls, suicide attempts, domestic violence, assaults and child abuse, alcohol-related injuries and injury emergency visits, hospitalizations and deaths. Reductions ranged from 27% to 65%. Because few trials were sufficiently large to assess effects on injuries, individual effect estimates were generally imprecise. We did not combine the results quantitatively because the interventions, patient populations, and outcomes were so diverse. The most commonly evaluated intervention was brief counseling in the clinical setting. This was studied in seven trials, in which injury-related deaths were reduced: relative risk (RR) 0.65; 95% confidence interval (CI) 0.21 to 2.00. However, this reduction may have been due to chance. The majority of trials of brief counseling also showed beneficial effects on diverse non-fatal injury outcomes.

REVIEWERS' CONCLUSIONS

Interventions for problem drinking appear to reduce injuries and their antecedents (e.g. falls, motor vehicle crashes, suicide attempts). Because injuries account for much of the morbidity and mortality from problem drinking, larger studies are warranted to evaluate the effect of treating problem drinking on injuries.

Biological markers in alcoholism

Alcohol biomarkers include tests indicative of acute or chronic alcohol consumption (state markers), and markers of a genetic predisposition to develop alcohol dependence after chronic exposure (trait markers). While a comprehensive trait marker for alcohol dependence has not been identified, a number of successful state markers for monitoring drinking status are used clinically. These tests provide direct or indirect ways to estimate the amounts of alcohol consumed and the duration of ingestion, and to detect any harmful effects on body functions resulting from long-term misuse. The most obvious method to prove recent drinking is by demonstrating the presence of ethanol in body fluids or breath, but, because ethanol is cleared fairly rapidly from the body, this method is limited to detect only very recent drinking. Measurement of urinary 5-hydroxytryptophol or ethyl glucuronide provide more sensitive methods to disclose recent drinking, because their washout constants are much longer than for ethanol. The liver functions test (GGT, AST and ALT in serum) and the mean corpuscular volume of erythrocytes (MCV) are among the standard diagnostic tools used to identify chronic alcohol exposure. The main disadvantage with these measures is that they have low sensitivity for recent excessive intake, and that raised levels may result from several causes besides heavy drinking, implying a low specificity for alcohol. Carbohydrate-deficient transferrin (CDT), which refers to changes in the carbohydrate composition of serum transferrin, is a more specific marker for identifying excessive alcohol consumption and monitoring abstinence during outpatient treatment. The alcohol biomarkers improves knowledge of drinking patterns in both individuals and populations, and they are also valuable tools for the objective evaluation of treatment efforts. Alcohol markers have, for example, found uses in early identification of at-risk and harmful drinking, and they help to monitor abstinence and relapse in response to outpatient treatment.
