Brief physician- and nurse practitioner-delivered counseling for high-risk drinkers: does it work?

A meta-analysis of the efficacy of nonphysician brief interventions for unhealthy alcohol use: implications for the patient-centered medical home

Brief physician interventions can reduce alcohol consumption. Physicians may not have the time to provide brief interventions, and it is unclear whether nonphysicians can do so effectively. We conducted a systematic review and meta-analysis to examine the efficacy of brief interventions by nonphysician clinicians for unhealthy alcohol use. We searched the English-language literature in MEDLINE and other databases covering the domains of alcohol problems, primary care, nonphysician, and brief interventions. Studies of brief interventions delivered at least in part by nonphysicians in primary care and examining drinking outcomes were included. Sensitivity analyses examined the effect of excluding studies that contributed disproportionately to the heterogeneity of results. Thirteen studies, conducted 1996-2008, met our criteria. Seven studies with a total of 2,633 patients were included in the meta-analysis. Nonphysician interventions were associated with 1.7 (95% confidence interval [CI]=-.03 to -3.5) fewer standard drinks per week than control conditions (p = .054). Excluding the one study that increased heterogeneity, the effect was smaller but reached statistical significance; nonphysician counseling was associated with 1.4 (95% CI = .3- 2.4) fewer standard drinks per week compared to control (p = .012). Nonphysician brief interventions are modestly effective at reducing drinking in primary care patients with unhealthy alcohol use.

Barriers and facilitators in implementing "prevention for positives" alcohol-reduction support: the perspectives of directors and providers in hospital-based HIV care centers

HIV-infected patients have considerable need for alcohol reduction support, and HIV care providers are strategically placed to implement a "prevention for positives" alcohol-reduction approach through alcohol screening and brief interventions (SBIs). To facilitate this approach, we provided alcohol SBI education and training to HIV care providers in four hospital-based, New York City HIV Care Centers in 2007. Interviews with the medical directors and 14 of the HIV care providers who attended the training identified barriers to implementing alcohol SBIs. These included limited time for alcohol screening, patients' incomplete disclosure of alcohol use, providers' perceptions that alcohol use is not a major problem for their patients, and provider specialization that assigns patients with problematic alcohol use to specifically designated providers. Identified facilitators for alcohol SBI implementation included adequate time to conduct the SBI; availability of information, tools, and key points to emphasize with HIV-infected patients; and use of a brief alcohol screening tool.

Alcohol screening and brief intervention in primary care: Absence of evidence for efficacy in people with dependence or very heavy drinking

ISSUES

Although screening and brief intervention (BI) in the primary-care setting reduces unhealthy alcohol use, its efficacy among patients with dependence has not been established. This systematic review sought to determine whether evidence exists for BI efficacy among patients with alcohol dependence identified by screening in primary-care settings.

APPROACH

We included randomised controlled trials (RCTs) extracted from eight systematic reviews and electronic database searches published through September 2009. These RCTs compared outcomes among adults with unhealthy alcohol use identified by screening who received BI in a primary-care setting with those who received no intervention.

KEY FINDINGS

Sixteen RCTs, including 6839 patients, met the inclusion criteria. Of these, 14 excluded some or all persons with very heavy alcohol use or dependence; one in which 35% of 175 patients had dependence found no difference in an alcohol severity score between groups; and one in which 58% of 24 female patients had dependence showed no efficacy.

CONCLUSION AND IMPLICATIONS

Alcohol screening and BI has efficacy in primary care for patients with unhealthy alcohol use, but there is no evidence for efficacy among those with very heavy use or dependence. As alcohol screening identifies both dependent and non-dependent unhealthy use, the absence of evidence for the efficacy of BI among primary-care patients with screening-identified alcohol dependence raises questions regarding the efficiency of screening and BI, particularly in settings where dependence is common. The finding also highlights the need to develop new approaches to help such patients, particularly if screening and BI are to be disseminated widely.[Saitz R. Alcohol screening and brief intervention in primary care: Absence of evidence for efficacy in people with dependence or very heavy drinking.

Conducting economic evaluations of screening and brief intervention for hazardous drinking: Methods and evidence to date for informing policy

ISSUES

Many policy review articles have concluded that alcohol screening and brief intervention (SBI) is both cost-effective and cost-beneficial. Yet a recent cost-effectiveness review for the United Kingdom's National Institute for Health and Clinical Excellence suggests that these conclusions may be premature.

APPROACH

This article offers a brief synopsis of the various types of economic analyses that may be applied to SBI, including cost analysis, cost-effectiveness analysis, cost-utility analysis, cost-benefit analysis and other types of economic evaluation. A brief overview of methodological issues is provided, and examples from the SBI evaluation literature are provided.

KEY FINDINGS, IMPLICATIONS AND CONCLUSIONS

The current evidence base is insufficient to draw firm conclusions about the cost, cost-effectiveness or cost-benefit of SBI and about the impact of SBI on health-care utilisation.[Cowell AJ, Bray JW, Mills MJ, Hinde JM. Conducting economic evaluations of screening and brief intervention for hazardous drinking: Methods and evidence to date for informing policy.

Risky drinking among community pharmacy customers in New Zealand and their attitudes towards pharmacist screening and brief interventions

INTRODUCTION AND AIMS

To estimate the prevalence of risky drinking among customers in community pharmacies and to explore customer attitudes towards screening and brief intervention (SBI).

DESIGN AND METHODS

Cross-sectional, anonymous survey, using random selection of community pharmacies in New Zealand to collect data using self-completion questionnaires and an opportunity to enter a prize draw. Participants were customers/patients attending the community pharmacy on a specific, randomly selected day (Monday to Friday) in one set week. Alcohol Use Disorder Identification Test (AUDIT)-C using a cut-off score of 5 was used to measure risky drinking. Attitudes towards pharmacists engaging in SBI for risky drinkers were measured.

RESULTS

2384 completed customer/patient questionnaires from 43 participating pharmacies. Almost 84% ever drank alcohol and using a score of 5 or more as a cut-off, 30% of the sample would be considered as risky drinkers. Attitudes were generally positive to pharmacists undertaking SBI. Logistic regression with AUDIT-C positive or negative as the dependent variable found those taking medicines for mental health and liver disease being more likely to score negative on the AUDIT-C, and smokers and those purchasing hangover cures were more likely than average to have a positive AUDIT-C screen.

DISCUSSION AND CONCLUSIONS

This study indicates there is scope for community pharmacists to undertake SBI for risky drinking, and that customers find this to be acceptable. Targeted screening may well be useful, in particular for smokers. Further research is required to explore the effectiveness of SBI for risky drinkers in this setting.

Behaviorally defined patient-centered communication--a narrative review of the literature

BACKGROUND

Touted by some as reflecting a better medical model and cited by the influential IOM report in 2000 as one of the six domains of quality care, patient-centered medicine has yet to fully establish its scientific attributes or to become mainstream. One proposed reason is failure to behaviorally define what the term 'patient-centered' actually means.

OBJECTIVES

(1) To identify patient-centered articles among all reported randomized controlled trials (RCT); (2) to identify those with specific behaviorally defined interventions; (3) to identify commonalities among the behavioral definitions; and (4) to evaluate the relationship of the well-defined RCTs to patient outcomes.

DATA SOURCES

Medline from April 2010 to 1975. ELIGIBILITY CRITERIA, PARTICIPANTS, AND INTERVENTIONS: RCTs having any specific, behaviorally defined patient-centered skill(s) in an intervention with some patient outcome involving real adult patients and providers in real clinical situations. APPRAISAL AND SYNTHESIS METHODS: Critical appraisal via narrative review.

RESULTS

The prevalence of any mention of patient-centeredness among 327,219 RCTs was 0.50% (1,475 studies), from which we identified only 13 studies (0.90%) where there were behaviorally-defined patient-centered skills in an intervention. Although there were too few studies to make clinical recommendations, we identified common features of the behavioral definitions used: all went well beyond identifying individual skills. Rather, skills were grouped, prioritized, and sequenced by virtually all, often describing a stepwise patient-centered approach to, variously, gather data, address emotions, or inform and motivate.

LIMITATIONS

The inherent subjectivity of our method for identifying behaviorally-defined studies could under- or over-represent truly replicable such studies considerably. Also, studies were few and very heterogeneous with interventions of widely differing intensity and foci.

CONCLUSIONS AND IMPLICATIONS

RCTs identified as patient-centered were rare, and <1% of these were behaviorally defined and, therefore, possibly replicable. There were many common behavioral definitions in the studies reported, and these can guide us in identifying agreed-upon patient-centered interventions, the immediate next-step in advancing the field.

Mechanisms of change in control group drinking in clinical trials of brief alcohol intervention: implications for bias toward the null

ISSUES

Reductions in control group consumption over time that are possibly related to research design affect the impact of brief alcohol interventions (BAI) in clinical settings.

APPROACH

We conducted a systematic review to identify research design factors that may contribute to control group change, strategies to limit these effects and implications for researchers. Studies with control group n > 30 were selected if they published baseline and outcome consumption data, conducted trials in clinical settings in Anglophone countries and did not censor gender or age.

KEY FINDINGS

Among 38 studies cited in 20 reviews through October 2009, 16 met criteria (n = 31-370). In 54%, controls received alcohol specific handouts, advice and/or referral. Both the number and depth of assessments were highly variable. The percentage change in consumption ranged from-0.10 to-0.84 (mean-0.32), and effect size from 0.04 to 0.70 (mean 0.37). Published data were insufficient for meta-analysis.

IMPLICATIONS

Researchers should consider strategies to reduce the impact of research design factors, such as procedures to enhance sample diversity, blind subjects to study purpose to limit social desirability bias, reduce the number and depth of instruments (assessment reactivity), and finally, analytic techniques to decrease the impact of outliers and regression to the mean.

CONCLUSIONS

This review identifies problems with retrospective analysis of predictors of control group change, and underscores the need to design prospective studies to permit identification, quantification and adjustment for potential sources of bias in BAI trials.

Primary care-based intervention to reduce at-risk drinking in older adults: a randomized controlled trial

AIMS

To examine whether a multi-faceted intervention among older at-risk drinking primary care patients reduced at-risk drinking and alcohol consumption at 3 and 12 months.

DESIGN

Randomized controlled trial.

SETTING

Three primary care sites in southern California.

PARTICIPANTS

Six hundred and thirty-one adults aged ≥ 55 years who were at-risk drinkers identified by the Comorbidity Alcohol Risk Evaluation Tool (CARET) were assigned randomly between October 2004 and April 2007 during an office visit to receive a booklet on healthy behaviors or an intervention including a personalized report, booklet on alcohol and aging, drinking diary, advice from the primary care provider and telephone counseling from a health educator at 2, 4 and 8 weeks.

MEASUREMENTS

The primary outcome was the proportion of participants meeting at-risk criteria, and secondary outcomes were number of drinks in past 7 days, heavy drinking (four or more drinks in a day) in the past 7 days and risk score.

FINDINGS

At 3 months, relative to controls, fewer intervention group participants were at-risk drinkers [odds ratio (OR) 0.41; 95% confidence interval (CI) 0.22-0.75]; they reported drinking fewer drinks in the past 7 days [rate ratio (RR) 0.79; 95% CI 0.70-0.90], less heavy drinking (OR 0.46; 95% CI 0.22-0.99) and had lower risk scores (RR 0.77 95% CI 0.63-0.94). At 12 months, only the difference in number of drinks remained statistically significant (RR 0.87; 95% CI 0.76-0.99).

CONCLUSIONS

A multi-faceted intervention among older at-risk drinkers in primary care does not reduce the proportions of at-risk or heavy drinkers, but does reduce amount of drinking at 12 months.

Do health educator telephone calls reduce at-risk drinking among older adults in primary care?

BACKGROUND

Alcohol screening and brief intervention for unhealthy alcohol use has not been consistently delivered in primary care as part of preventive healthcare.

OBJECTIVE

To explore whether telephone-based intervention delivered by a health educator is efficacious in reducing at-risk drinking among older adults in primary care settings.

DESIGN

Secondary analyses of data from a randomized controlled trial.

PARTICIPANTS

Subjects randomized to the intervention arm of the trial (n = 310).

INTERVENTIONS

Personalized risk reports, advice from physicians, booklet about alcohol and aging, and up to three telephone calls from a health educator. All interventions were completed before the three-month follow-up.

MEASUREMENTS

Risk outcomes (at-risk or not at-risk) at 3 and 12 months after enrollment.

MAIN RESULTS

In univariate analyses, compared to those who remained at risk, those who achieved not at-risk outcome at 3 months were more likely to be women, Hispanic or non-white, have lower levels of education, consume less alcohol, drink less frequently, and have lower baseline number of risks. In mixed-effects logistic regression models, completing all three health educator calls increased the odds of achieving not at-risk outcome compared to not completing any calls at 3 months (OR 5.31; 95% CI 1.92-14.7; p = 0.001), but not at 12 months (OR 2.01; 95% CI 0.71-5.67; p = 0.18).

CONCLUSIONS

Telephone-based intervention delivered by a health educator was moderately efficacious in reducing at-risk drinking at 3 months after enrollment among older adults receiving a multi-faceted intervention in primary care settings; however, the effect was not sustained at 12 months.

What may stimulate general practitioners to undertake screening and brief intervention for excess alcohol consumption in Slovenia? A focus group study

Screening and brief intervention (SBI) presents an effective early response by healthcare professionals to their patients' alcohol-related problems. This qualitative research study used focus group discussions with general practitioners (GPs) to identify incentives that may increase the use of SBI in Slovene general practice. Seven categories of actions that may improve the use of SBI were identified: motivation, professional institution, financial support, adequate knowledge and skills, community support, workload (i.e. relief from the burden of current obligations in order to allow more time for prevention), and record keeping (suitable medical documentation). Several of these actions can be changed by the GPs themselves (motivation, adequate knowledge and skills, and record keeping), while the remaining four require more extensive community action on the part of society as a whole, e.g. government intervention. The results of this study will guide future changes in the way that prevention strategies for excess alcohol consumption will be implemented in Slovenia.

Efficacy of brief interventions in clinical care settings for persons living with HIV

Prevention of HIV transmission from patients living with HIV (PLH) is a high national priority and strategies that are easy to implement and sustain to eliminate sexual transmission acts among PLH are needed. We evaluated a brief intervention that focused primarily on the enhancing motivations and encouraging PLH to act in accordance with their values without providing the intensity of the existing evidence-based programs for PLH. Using a quasiexperimental design, six medical clinics in Los Angeles County, CA, were evaluated across three intervention conditions: 1) computerized delivery; 2) provider delivery; or 3) standard care. We examined longitudinal changes in patients' reports of the number of HIV-negative (HIV-) or serostatus-unknown sexual partners and the number of unprotected vaginal and anal sex acts. Among 566 PLH, PLH in the computerized delivery condition reported a significant decrease in the number of HIV-/unknown sexual partners compared with the provider delivery and standard care conditions and a significant decrease in the number of unprotected sex acts in comparison to the standard care condition. Computerized motivational interventions delivered in waiting rooms at medical clinics may be an efficient strategy to reduce unprotected sex acts among PLH.

Brief Alcohol Intervention Among At-Risk Drinkers with Diabetes

Twenty-eight patients with diabetes who screened positive for at-risk drinking were assigned to brief alcohol intervention (BAI) (n = 14) or standard care (SC) (n = 14) treatment conditions. All participants completed a baseline interview and one-, three, and six-month follow-up interviews. Across the six-month follow-up period, there was a significantly greater reduction in quantity of alcohol consumed in the BAI group. At the six-month follow-up, the BAI group had a greater reduction in quantity of alcohol consumed, percentage of heavy drinking days, and frequency of drinking. Reductions in alcohol use were associated with improved adherence in certain components of diabetes self-care behavior. The results of this study suggest that brief alcohol interventions are efficacious in reducing alcohol use among at-risk drinkers with diabetes and that reductions in alcohol use may result in some improvements in adherence to diabetes self-care behavior.

Use of an electronic clinical reminder for brief alcohol counseling is associated with resolution of unhealthy alcohol use at follow-up screening

BACKGROUND/OBJECTIVE

Brief alcohol counseling is a foremost US prevention priority, but no health-care system has implemented it into routine care. This study evaluated the effectiveness of an electronic clinical reminder for brief alcohol counseling ("reminder"). The specific aims were to (1) determine the prevalence of use of the reminder and (2) evaluate whether use of the reminder was associated with resolution of unhealthy alcohol use at follow-up screening.

METHODS

The reminder was implemented in February 2004 in eight VA clinics where providers routinely used clinical reminders. Patients eligible for this retrospective cohort study screened positive on the AUDIT-C alcohol screening questionnaire (February 2004-April 2006) and had a repeat AUDIT-C during the 1-36 months of follow-up (mean 14.5). Use of the alcohol counseling clinical reminder was measured from secondary electronic data. Resolution of unhealthy alcohol use was defined as screening negative at follow-up with a >/=2-point reduction in AUDIT-C scores. Logistic regression was used to identify adjusted proportions of patients who resolved unhealthy alcohol use among those with and without reminder use.

RESULTS

Among 4,198 participants who screened positive for unhealthy alcohol use, 71% had use of the alcohol counseling clinical reminder documented in their medical records. Adjusted proportions of patients who resolved unhealthy alcohol use were 31% (95% CI 30-33%) and 28% (95% CI 25-30%), respectively, for patients with and without reminder use (p-value = 0.031).

CONCLUSIONS

The brief alcohol counseling clinical reminder was used for a majority of patients with unhealthy alcohol use and associated with a moderate decrease in drinking at follow-up.

Efficacy of physician-delivered brief counseling intervention for binge drinkers

BACKGROUND

Binge drinking is a common pattern of alcohol use in the US. However, no studies have evaluated the effectiveness of brief interventions targeting only binge drinkers.

METHODS

Randomized controlled clinical trial with a 12-month follow-up period conducted from March 1, 2003 to March 1, 2006 in Spain. Of a screened population of 15,325 patients seeking routine medical care from their primary care providers, patients who met inclusion criteria were randomized into an experimental group (n=371) or a control group (n=381). The primary outcome measures were the frequency of binge drinking episodes and weekly alcohol intake.

RESULTS

There were no significant differences at baseline between groups in alcohol use and demographic variables. At the end of the 12-month follow-up period, there were significant reductions in binge-drinking status (52.2% vs 67.2%, P <.001), number of episodes of binge drinking (1.14 vs 1.56, P <.001), number of drinks weekly (19.2 vs 22.4, P <.001), and frequency of excessive alcohol intake in 7 days (47.9% vs 66.6%, P >.001).

CONCLUSIONS

This study provided evidence that screening and brief counseling delivered by a primary care physician as part of regular health care significantly reduced binge drinking episodes in binge drinkers.

Alcohol, drugs and trauma: consequences, screening and intervention in 2009

Alcohol use is a preventable cause of injury as it doubles the risk of re-injury and increases mortality. For this reason, the American College of Surgeons, Committee on Trauma had mandated a screening and subsequent intervention strategy for all Level I centres, and there is good evidence to support the efficacy of such programmes. Clinicians can play a key role in reducing injury related to alcohol use through their participation in these programmes. Although validated screening tools and evidence to support brief interventions for alcohol use exist, the benefit of these experiences for other recreational drugs awaits further research in this area. In the meantime, the implementation of alcohol screening and brief intervention programmes across all trauma programmes and emergency departments should become a global healthcare priority.

Brief screens for detecting alcohol use disorder among 18-20 year old young adults in emergency departments: Comparing AUDIT-C, CRAFFT, RAPS4-QF, FAST, RUFT-Cut, and DSM-IV 2-Item Scale

BACKGROUND

This study compared six of the briefest screening instruments for detecting DSM-IV-defined Alcohol Use Disorder (AUD) among older adolescents treated in Emergency Departments (ED).

METHODS

The AUDIT-C, the RAPS4-QF, the FAST, the CRAFFT, the RUFT-Cut, and 2-Items from the Diagnostic and Statistical Manual IV of the American Psychiatric Association [American Psychiatric Association (1994). Diagnostic and Statistical Manual of Psychiatric Disorders, (1994) (DSM-IV). 4th ed. Washington D.C.: American Psychiatric Association] criteria for AUD (heretofore referred to as the DSM-IV 2-Item Scale) were evaluated against the criterion of a current DSM-IV diagnosis of either alcohol abuse or dependence. The instruments were administered to 181 alcohol-using older adolescents (57% males; age range 18-20 years) in an ED and compared using Receiver Operator Characteristic (ROC) analyses against the criterion of a current DSM-IV diagnosis of alcohol abuse or dependence.

RESULTS

Of these instruments, the DSM-IV 2-Item Scale performed best for identifying AUD (88% sensitivity and 90% specificity), followed by the FAST and the AUDIT-C.

CONCLUSIONS

Two items from the DSM-IV criteria for AUD performed best for identifying ED-treated older adolescents with alcohol use disorders. The FAST and AUDIT-C performed well, but are longer and more difficult to score in the hectic environment of the Emergency Department.

Brief interventions for heavy alcohol users admitted to general hospital wards

BACKGROUND

Brief interventions involve a time-limited intervention focusing on changing behaviour. They are often motivational in nature using counselling skills to encourage a reduction in alcohol consumption.

OBJECTIVES

To determine whether brief interventions reduce alcohol consumption and improve outcomes for heavy alcohol users admitted to general hospital inpatient units.

SEARCH STRATEGY

We searched the Cochrane Drug and Alcohol Group Register of Trials (June 2008) the Cochrane Central Register of Controlled Trials (The Cochrane Library 2, 2008), MEDLINE January 1966-June 2008, CINAHL 1982-June 2008, EMBASE 1980-June 2008 using the search strategy developed by the Cochrane Drug and Alcohol Group. We hand searched relevant journals, conference proceedings and contacted experts in the field.

SELECTION CRITERIA

All prospective randomised controlled trials and controlled clinical trials were eligible for inclusion. Participants were adults (16 years or older) admitted to general inpatient hospital care for any reason other than specifically for alcohol treatment and received brief interventions (of up to 3 sessions) compared to no or regular treatment.

DATA COLLECTION AND ANALYSIS

Three reviewers independently selected the studies and extracted data. Where appropriate random effects meta-analysis and sensitivity analysis were performed.

MAIN RESULTS

Eleven studies involving 2441 participants were included in this review. Three results were non significant and one result was significant mean alcohol consumption per week change scores from baseline (P0.02).

AUTHORS' CONCLUSIONS

The evidence for brief interventions delivered to heavy alcohol users admitted to general hospital is still inconclusive. From data extracted from two studies it appears that alcohol consumption could be reduced at one year follow up though further research is recommended. Few studies have been retrieved and the results were difficult to combine because of the different measures used to assess alcohol consumption.

Cost-effectiveness of screening for unhealthy alcohol use with % carbohydrate deficient transferrin: results from a literature-based decision analytic computer model

BACKGROUND

The %carbohydrate deficient transferrin (%CDT) test offers objective evidence of unhealthy alcohol use but its cost-effectiveness in primary care conditions is unknown.

METHODS

Using a decision tree and Markov model, we performed a literature-based cost-effectiveness analysis of 4 strategies for detecting unhealthy alcohol use in adult primary care patients: (i) Questionnaire Only, using a validated 3-item alcohol questionnaire; (ii) %CDT Only; (iii) Questionnaire followed by %CDT (Questionnaire-%CDT) if the questionnaire is negative; and (iv) No Screening. For those patients screening positive, clinicians performed more detailed assessment to characterize unhealthy use and determine therapy. We estimated costs using Medicare reimbursement and the Medical Expenditure Panel Survey. We determined sensitivity, specificity, prevalence of disease, and mortality from the medical literature. In the base case, we calculated the incremental cost-effectiveness ratio (ICER) in 2006 dollars per quality-adjusted life year ($/QALY) for a 50-year-old cohort.

RESULTS

In the base case, the ICER for the Questionnaire-%CDT strategy was $15,500/QALY compared with the Questionnaire Only strategy. Other strategies were dominated. When the prevalence of unhealthy alcohol use exceeded 15% and screening age was <60 years, the Questionnaire-%CDT strategy costs less than $50,000/QALY compared to the Questionnaire Only strategy.

CONCLUSIONS

Adding %CDT to questionnaire-based screening for unhealthy alcohol use was cost-effective in our literature-based decision analytic model set in typical primary care conditions. Screening with %CDT should be considered for adults up to the age of 60 when the prevalence of unhealthy alcohol use is 15% or more and screening questionnaires are negative.

Change over time in alcohol consumption in control groups in brief intervention studies: systematic review and meta-regression study

Reactivity to assessment has attracted recent attention in the brief alcohol intervention literature. This systematic review sought to examine the nature of change in alcohol consumption over time in control groups in brief intervention studies. Primary studies were identified from existing reviews published in English language, peer-reviewed journals between 1995 and 2005. Change in alcohol consumption and selected study-level characteristics for each primary study were extracted. Consumption change data were pooled in random effects models and meta-regression was used to explore predictors of change. Eleven review papers reported the results of 44 individual studies. Twenty-six of these studies provided data suitable for quantitative study. Extreme heterogeneity was identified and the extent of observed reduction in consumption over time was greater in studies undertaken in Anglophone countries, with single gender study participants, and without special targeting by age. Heterogeneity was reduced but was still substantial in a sub-set of 15 general population studies undertaken in English language countries. The actual content of the control group procedure itself was not predictive of reduction in drinking, nor were a range of other candidate variables including setting, the exclusion of dependent drinkers, the collection of a biological sample at follow-up, and duration of study. Further investigations may yield novel insights into the nature of behaviour change with potential to inform brief interventions design.

Improved prevention counseling by HIV care providers in a multisite, clinic-based intervention: Positive STEPs

The Centers for Disease Control and Prevention have recommended that HIV care clinics incorporate prevention into clinical practice. This report summarizes HIV care providers' attitudes and counseling practices before and after they received training to deliver a counseling intervention to patients. Providers at seven HIV clinics received training in delivering a counseling intervention (Positive STEPs) to their patients and completed baseline and follow-up questionnaires to measure changes in prevention parameters. A cohort of patients at each clinic was independently surveyed about counseling experiences. Compared with the pretraining period, providers' self-ratings collected after they initiated the intervention showed significant (p < .05) positive changes in attitudes, comfort, self-efficacy, and frequency of delivering prevention counseling. Patients reported an increase in prevention counseling received from providers after training. The findings indicate that the training and delivery of the Positive STEPs intervention was associated with positive changes in providers' attitudes and HIV prevention counseling to patients.

At-risk drinking among diabetic patients

Diabetes Mellitus is a serious chronic disease, affecting an increasing number of individuals worldwide. Adherence to diabetes self-care behaviors is key to the successful management of the disease. At-risk drinking is common among diabetic patients and is associated with inferior diabetes treatment adherence and outcomes, resulting in increased mortality and morbidity. Furthermore, individuals with diabetes who engage in at-risk drinking are also in danger of incurring the negative consequences of at-risk drinking found in the general population. Research suggests that alcohol use screening and intervention do not commonly occur during the course of primary care treatment for diabetes. While methods for reducing alcohol use in this population have been largely unexplored to date, brief interventions to reduce at-risk drinking have been well-validated in other patient populations and offer the promise to reduce at-risk drinking among diabetic patients, resulting in improved diabetes treatment adherence and outcomes.

An electronic linkage system for health behavior counseling effect on delivery of the 5A's

BACKGROUND

A variety of factors limit the ability of clinicians to offer intensive counseling to patients with unhealthy behaviors, and few patients (2%-5%) are referred to the community counseling resources that do offer such assistance. A system that could increase referrals through an efficient collaborative partnership between community programs and clinicians could have major public health implications; such was the subject of this feasibility evaluation.

METHODS

At nine primary care practices, an electronic linkage system (eLinkS) was instituted to promote health behavior counseling and to automate patient referrals to community counseling services. Patients were offered 9 months of free counseling for weight loss, smoking cessation, and problem drinking at a choice of venues: group counseling, telephone counseling, computer care, and usual care. The delivery of behavioral counseling, measured by the 5A's (ask, address, advise, assess, agree, arrange) and patients' reported experiences with eLinkS, was examined.

RESULTS

For 5 weeks eLinkS was used, until high referral volumes depleted counseling funds. Of the 5679 patients visiting the practices, 71% had an unhealthy behavior. Of these patients, 10% were referred for intensive counseling from a community program, most often for weight loss. Counseling and referrals occurred regardless of visit type--wellness, acute, or chronic care. eLinkS was used more often for middle-aged adults and women and by more-experienced clinicians.

CONCLUSIONS

The intervention increased the rate at which patients were referred for intensive behavioral counseling compared to current practice norms. Given the evidence that intensive counseling is more effective in promoting behavior change, implementing eLinkS could have substantial public health benefits.

The challenges of assessing fidelity to physician-driven HIV prevention interventions: lessons learned implementing Partnership for Health in a Los Angeles HIV clinic

Documenting fidelity to HIV prevention interventions is critical to ensure consistency in intervention implementation and necessary for measuring intervention exposure and, ultimately, outcomes. Significant variation from prescribed protocols or inconsistent implementation can jeopardize the integrity of evaluation research and render outcomes uninterpretable. There is increasing support for HIV prevention models targeting seropositive individuals designed to be delivered by physicians during clinic visits. Assessing fidelity to physician-delivered interventions that occur during clinical exams present unique challenges. This paper presents findings from various data sources designed to track intervention fidelity and exposure to the Partnership for Health intervention, a physician-delivered HIV prevention intervention implemented in an urban community HIV clinic. We present findings from chart abstraction data, patient surveys and exit interviews, and provider qualitative interviews. Lessons learned and recommendations for maximizing the accuracy and validity of fidelity assessment in future evaluations of HIV prevention interventions in primary care settings are considered.

A profile of concurrent alcohol and alcohol-interactive prescription drug use in the US population

BACKGROUND

The risk of adverse events among alcohol-interactive medication users can occur with one standard alcoholic drink. Research on the extent to which this occurs is scant.

OBJECTIVE

To examine the prevalence and correlates of concurrent alcohol and alcohol-interactive (AI) medication use across different levels of risk for an alcohol-related adverse event in a nationally representative sample of American adults.

METHODS

Cross-sectional analysis of past year, self-reported drinking history as well as past month, self-reported and visually inspected prescription drug use data from the 1999-2000 and 2001-2002 NHANES questionnaire section (n = 8,246). Medications were considered AI if concurrent use of alcohol and the prescription drug could intensify the effects of alcohol, resulting in increased sedation, drowsiness, or dizziness. Weighted prevalence estimates and polytomous logistic regression accounted for the complex survey design.

RESULTS

Overall, 13.5% took prescription AI medications, of which 5.6% reported alcohol consumption of three or more drinks on each drinking occasion. Correlates of such use were being a man [adjusted odds ratio (AOR): 4.37; 95% confidence interval (CI): 1.84-10.35], between the ages of 20 and 54 (AOR=12.28; 95% CI: 3.12-48.25), and currently smoking (AOR: 2.61; 95% CI: 1.28-5.29), with alcohol-abstaining AI users as the referent group.

CONCLUSIONS

Combining alcohol and AI medications is a common phenomenon, and the risk of alcohol-related adverse drug events may be nontrivial. Screening for alcohol use before prescribing AI medications would be prudent. Better communication regarding the dangers of mixing alcohol with AI medications is warranted.

Screening and brief interventions for alcohol: attitudes, knowledge and experience of community pharmacists in Auckland, New Zealand

INTRODUCTION

Screening and brief intervention (SBI) for alcohol consumption in primary care have been shown to be effective in reducing drinking. This role has not been taken up by community pharmacists. This study aimed to explore attitudes, knowledge, barriers and incentives towards involvement of community pharmacists in New Zealand with problem drinkers.

METHOD

A postal survey (three mailshots) of community pharmacies was undertaken in Auckland, New Zealand, followed by a 10% random sample non-responder-follow-up.

RESULTS

A response rate of 39.1% to the postal survey was obtained. In general, knowledge of alcohol content of drinks and recommended safe drinking limits was poor. Respondents were generally well motivated towards undertaking this role, but lacked knowledge, skills and confidence. On follow-up, non-responders were found to be less knowledgeable, but had similar attitudes to respondents, indicating potential for extrapolation with regard to beliefs and views on this subject.

DISCUSSION

This novel study has found that there is potential for involvement of community pharmacists in New Zealand in SBI for problem drinkers. Lack of knowledge can be remedied relatively easily; greater hurdles such as lack of skills, and lack of confidence may be offset by the high level of motivation of this group. This is an area where community pharmacists can further their professional scope of practice by being in an essential position to provide this service.

Do brief interventions which target alcohol consumption also reduce cigarette smoking? Systematic review and meta-analysis

Brief interventions are known to be effective in changing both substance use and other health-compromising behaviors. It is unknown whether they may have secondary effects on behaviors which are not specifically targeted. The literature on brief alcohol interventions was selected to explore this possibility, with a study focus on secondary impact on cigarette smoking. The CINAHL, EMBASE, MEDLINE and PSYCINFO bibliographic databases were searched for reviews of brief alcohol intervention studies published in English language, peer-reviewed journals between 1995 and 2005. Authors of primary studies identified in the reviews were contacted to ascertain whether or not their studies had collected cigarette smoking data and, if available, to obtain data. Random effect models were used to pool data for meta-analysis. Eleven review papers reported the results of 41 individual primary studies which were included in this systematic review. Fourteen of these studies collected cigarette smoking outcome data, of which 7 studies still had information available and provided these data for meta-analysis. There were no between-group differences in smoking cessation or reduction across these studies. High levels of smoking cessation were detected in both brief intervention and control groups with much heterogeneity between studies. Brief alcohol interventions do not also reduce cigarette smoking, and it appears unlikely that there exist other important secondary effects. The behavioral consequences of brief intervention study participation itself warrant further study.

The Japanese national health screening and intervention program aimed at preventing worsening of the metabolic syndrome

Similar to the healthcare systems in other industrialized countries, the Japanese healthcare system is facing the problem of increasing medical expenditure. In Japan, this situation may be primarily attributed to advanced technological developments, an aging population, and increasing patient demand. Japan also faces the problem of a declining youth population due to a low birth rate. Taken together, these problems present the healthcare system with a very difficult financial situation. Several reforms have been undertaken to contain medical expenditure, such as increasing employee copayment for health insurance from 10% to 20% in 1997 and from 20% to 30% in 2003 in order to curb unnecessary visits to medical institutions. Since the aging of the Japanese population is inevitable, a suitable method to contain medical expenditure may be to screen individuals who are likely to develop lifestyle-related diseases and conduct early intervention programs for them to prevent the development of diseases such as myocardial infarction or stroke that are costly to treat. If this goal is attained, it may contribute to the containment of medical expenditure as well as to improving the quality of life of the elderly. Therefore, the Japanese Ministry of Health, Labor and Welfare has decided to introduce a nationwide health screening and intervention program specifically targeting the metabolic syndrome commencing April 2008. Here, we discuss (1) the background of the Japanese healthcare system and the problems facing it, (2) the underlying objective and details of the new screening program, and (3) the expected impact of the program.

Allowing for uncertainty due to missing data in meta-analysis--part 2: hierarchical models

We propose a hierarchical model for the analysis of data from several randomized trials where some outcomes are missing. The degree of departure from a missing-at-random assumption in each arm of each trial is expressed by an informative missing odds ratio (IMOR). We require a realistic prior for the IMORs, including an assessment of the prior correlation between IMORs in different arms and in different trials. The model is fitted by Monte Carlo Markov Chain techniques. By applying the method in three different data sets, we show that it is possible to appropriately capture the extra uncertainty due to missing data, and we discuss in what circumstances it is possible to learn about the IMOR.

Low identification of alcohol use disorders in general practice in England

AIMS

The prevalence of alcohol use disorders (AUDs) in the United Kingdom is estimated at 25%, and primary care has been identified as the first line of treatment for this population. However, there is a paucity of evidence regarding the current rates of identification of AUDs in primary care. The aim of the present study was to compare the observed rates of AUDs in general practice with expected rates, which are based on general population prevalence rates of AUDs.

DESIGN, PARTICIPANTS AND MEASUREMENTS

Epidemiological data on individuals aged 16-64 years with an AUD was obtained from the General Practice Research Database. General population prevalence rates of AUDs were obtained from the Psychiatric Morbidity Survey. Chi(2) tests and identification ratios were used to analyse the data.

RESULTS

There was a significant relationship between type of AUD and identification (chi(2)=1466.89, P<0.001), and general practitioners were poorer at identifying harmful/hazardous drinkers when compared with dependent drinkers. No gender differences in the identification of hazardous/harmful drinking were found, but female dependent drinkers were significantly more likely to be identified than males (identification ratio 0.07; 95% confidence interval 0.06-0.07). The identification of AUDs was significantly lower for the 16-24-year age group compared with all other age groups.

CONCLUSION

Despite attempts at targeting hazardous/harmful drinkers for brief interventions in primary care, the present findings suggest that this group are still under-identified. Furthermore, this under-identification is even more apparent in men and in young people who have high general population prevalence rates for AUDs. In conclusion, increasing identification rates could be incorporated into brief intervention strategies in primary care.

Substance abuse treatment in human immunodeficiency virus: the role of patient-provider discussions

Substance abuse treatment is associated with decreases in human immunodeficiency virus (HIV) risk behavior and can improve HIV outcomes. The purpose of this study was to examine factors associated with substance abuse treatment utilization, including patient-provider discussions of substance use issues. We surveyed 951 HIV-infected adults receiving care at 14 HIV Research Network primary care sites regarding drug and alcohol use, substance abuse treatment, and provider discussions of substance use issues. Although 71% reported substance use, only 24% reported receiving substance abuse treatment and less than half reported discussing substance use issues with their HIV providers. In adjusted logistic regression models, receipt of substance abuse treatment was associated with patient-provider discussions. Patient-provider discussions of substance use issues were associated with current drug use, hazardous or binge drinking, and Black race or ethnicity, though substance use was comparable between Blacks and Whites. These data suggest potential opportunities for improving engagement in substance abuse treatment services.

A web-based Alcohol Clinical Training (ACT) curriculum: is in-person faculty development necessary to affect teaching?

BACKGROUND

Physicians receive little education about unhealthy alcohol use and as a result patients often do not receive efficacious interventions. The objective of this study is to evaluate whether a free web-based alcohol curriculum would be used by physician educators and whether in-person faculty development would increase its use, confidence in teaching and teaching itself.

METHODS

Subjects were physician educators who applied to attend a workshop on the use of a web-based curriculum about alcohol screening and brief intervention and cross-cultural efficacy. All physicians were provided the curriculum web address. Intervention subjects attended a 3-hour workshop including demonstration of the website, modeling of teaching, and development of a plan for using the curriculum. All subjects completed a survey prior to and 3 months after the workshop.

RESULTS

Of 20 intervention and 13 control subjects, 19 (95%) and 10 (77%), respectively, completed follow-up. Compared to controls, intervention subjects had greater increases in confidence in teaching alcohol screening, and in the frequency of two teaching practices - teaching about screening and eliciting patient health beliefs. Teaching confidence and teaching practices improved significantly in 9 of 10 comparisons for intervention, and in 0 comparisons for control subjects. At follow-up 79% of intervention but only 50% of control subjects reported using any part of the curriculum (p = 0.20).

CONCLUSION

In-person training for physician educators on the use of a web-based alcohol curriculum can increase teaching confidence and practices. Although the web is frequently used for dissemination, in-person training may be preferable to effect widespread teaching of clinical skills like alcohol screening and brief intervention.

Clinician-patient communication about physical activity in an underserved population

BACKGROUND

The 5A (Ask, Advise, Agree, Assist, Arrange) model, used to promote patient behavior changes in primary care, can also be applied to physical activity. Our goal was to assess primary care physicians' use of the 5A model in discussions with underserved populations about physical activity.

METHODS

We analyzed 51 audio-recorded, transcribed office visits on randomly selected patient care days and after-visit patient surveys with adults in 2 community health centers in Rochester, New York.

RESULTS

The patient sample was 51% African-American and predominantly female (70%), with the majority having a high school-level education or less (66%) and an annual household income < dollars 39,000 (57%). Physical activity was discussed during 19 of the 51 visits, which included 16 (84%) visits with "Ask"; 10 (53%) with "Advise"; 4 (21%) with "Agree"; 5 (26%) with "Assist"; and 0 with "Arrange" statements. Most discussions of physical activity contained several Ask or Advise statements but few Agree, Assist, or Arrange statements.

CONCLUSION

Communication about physical activity that included Agree, Arrange, and Assist statements of the 5A model was infrequent. Health promotion interventions in underserved populations should target these steps and prompt patients to initiate communication to improve physical activity.

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, Brief Intervention, and Referral to Treatment (SBIRT): toward a public health approach to the management of substance abuse

Screening, Brief Intervention, and Referral to Treatment (SBIRT) is a comprehensive and integrated approach to the delivery of early intervention and treatment services through universal screening for persons with substance use disorders and those at risk. This paper describes research on the components of SBIRT conducted during the past 25 years, including the development of screening tests, clinical trials of brief interventions and implementation research. Beginning in the 1980s, concerted efforts were made in the US and at the World Health Organization to provide an evidence base for alcohol screening and brief intervention in primary health care settings. With the development of reliable and accurate screening tests for alcohol, more than a hundred clinical trials were conducted to evaluate the efficacy and cost effectiveness of alcohol screening and brief intervention in primary care, emergency departments and trauma centers. With the accumulation of positive evidence, implementation research on alcohol SBI was begun in the 1990s, followed by trials of similar methods for other substances (e.g., illicit drugs, tobacco, prescription drugs) and by national demonstration programs in the US and other countries. The results of these efforts demonstrate the cumulative benefit of translational research on health care delivery systems and substance abuse policy. That SBIRT yields short-term improvements in individuals' health is irrefutable; long-term effects on population health have not yet been demonstrated, but simulation models suggest that the benefits could be substantial.

Brief motivational interviewing for teens at risk of substance use consequences: a randomized pilot study in a primary care clinic

The current study examined the impact of a brief motivational interviewing (MI) intervention (Project CHAT) on alcohol consumption and drug use for high-risk teens in a primary care clinic that provides health care for underserved populations. Youth (N=42, 48% male) were screened, and those eligible completed a baseline survey. Baseline survey completers were randomly assigned to usual care or to an MI intervention and completed a 3-month follow-up survey. The sample (age 12 to 18 years) was 85.7% Hispanic or Latino, 9.5% African American, and 4.8% White. At the 3-month follow-up, Project CHAT teens reported less marijuana use, lower perceived prevalence of marijuana use, fewer friends who used marijuana, and lower intentions to use marijuana in the next 6 months, as compared to teens assigned to usual care. Providing this type of brief intervention is a viable approach to working with high-risk teens to decrease substance use.

Prevention and health promotion and evidence-based fields of nursing - a literature review

This paper summarizes the evidence constituting the foundation for preventive and health promotive work performed by nurses in primary care. This is a systematic literature review in six scientific databases. Forty original articles and 16 literature reviews met the inclusion criteria. After both authors independently read the articles, 25 were excluded and 15 included. One article was judged to be of high quality, five of medium quality and 10 of low quality. The articles of high and medium quality focused on alcohol counselling, coronary heart disease and diabetes. Of the 16 literature reviews from the Cochrane Library, 10 were found to be relevant and presented evidence. The subjects included smoking cessation, breast-feeding, prevention of falls among the elderly, asthma in children, diabetes and cardiovascular disease. Few studies in the area of prevention and health promotion are of adequate scientific quality, resulting in limited evidence for the effects of interventions.

Effect of training on primary care residents' performance in brief alcohol intervention: a randomized controlled trial

BACKGROUND

Brief alcohol interventions (BAI) reduce alcohol use and related problems in primary care patients with hazardous drinking behavior. The effectiveness of teaching BAI on the performance of primary care residents has not been fully evaluated.

METHODS

A cluster randomized controlled trial was conducted with 26 primary care residents who were randomized to either an 8-hour, interactive BAI training workshop (intervention) or a lipid management workshop (control). During the 6-month period after training (i.e., from October 1, 2003 to March 30, 2004), 506 hazardous drinkers were identified in primary care, 260 of whom were included in the study. Patients were interviewed immediately and then 3 months after meeting with each resident to evaluate their perceptions of the BAI experience and to document drinking patterns.

RESULTS

Patients reported that BAI trained residents: conducted more components of BAI than did controls (2.4 vs 1.5, p = .001); were more likely to explain safe drinking limits (27% vs 10%, p = .001) and provide feedback on patients' alcohol use (33% vs 21%, p = .03); and more often sought patient opinions on drinking limits (19% vs 6%, p = .02). No between-group differences were observed in patient drinking patterns or in use of 9 of the 12 BAI components.

CONCLUSIONS

The BAI-trained residents did not put a majority of BAI components into practice, thus it is difficult to evaluate the influence of BAI on the reduction of alcohol use among hazardous drinkers.

Brief alcohol intervention and alcohol assessment do not influence alcohol use in injured patients treated in the emergency department: a randomized controlled clinical trial

AIMS

To evaluate the effectiveness of brief alcohol intervention (BAI) in reducing alcohol use among hazardous drinkers treated in the emergency department (ED) after an injury; in addition it tests whether assessment of alcohol use without BAI is sufficient to reduce hazardous drinking.

DESIGN

Randomized controlled clinical trial with 12-month follow-up conducted between January 2003 and June 2005.

SETTING

Urban academic emergency department (ED) of the Lausanne University Hospital, Lausanne, Switzerland.

PARTICIPANTS

A total of 5136 consecutive patients attending ED after an injury completed a seven-item general and a three-item alcohol screen and 1472 (28.7%) were positive for hazardous drinking according to the National Institute on Alcohol Abuse and Addiction definition; of these 987 (67.1%) were randomized into a BAI group (n = 310) or a control group with screening and assessment (n = 342) or a control group with screening only (n = 335) and then a total of 770 patients (78.0%) completed the 12-month follow-up procedures.

INTERVENTION

A single 10-15-minute session of standardized BAI conducted by a trained research assistant.

MEASUREMENTS

Percentage of participants who have changed to low-risk drinking at follow-up.

FINDINGS

Data obtained at 12 months indicated that similar proportions were low-risk drinkers in BAI versus control groups with and without assessment (35.6%, 34.0%, 37.0%, respectively, P = 0.71). Data also indicated similar reductions in drinking frequency, quantity, binge drinking frequency and Alcohol Use Disorders Identification Test (AUDIT) scores across groups. All groups reported similar numbers of days hospitalized and numbers of medical consults in the last 12 months. A model including age groups, gender, AUDIT and injury severity scores indicated that BAI had no influence on the main alcohol use outcome.

CONCLUSIONS

This study provides the evidence that a 10-15-minute BAI does not decrease alcohol use and health resource utilization in hazardous drinkers treated in the ED, and demonstrates that commonly found decreases in hazardous alcohol use in control groups cannot be attributed to the baseline alcohol assessment.

Practitioner-level predictors of alcohol problems detection and management activities

The alcohol health services literature suggests that a potential problem with promoting secondary prevention is an existing educational focus on alcohol dependency.

AIMS

This study explores practitioner-level predictors of health professionals' self-reported detection and management activities in an effort to inform this question.

PARTICIPANTS

The participants consisted of a random sample of licensed physicians and nurse practitioners in a northern California county.

MEASUREMENT

Participants completed a self-administered questionnaire on beliefs and practices regarding patients with alcohol problems and at-risk drinkers.

FINDINGS

The results indicate that prior alcohol education predicted clinical practices to address known or suspected drinking problems, but not those at-risk or without observable symptoms. In addition, stigmatizing beliefs about problem drinkers discouraged use of blood tests even when awareness of a drinking problem existed.

CONCLUSIONS

The conclusions are that existing models of alcohol education appear to convey a tertiary focus, and do not cover secondary prevention sufficiently to challenge the deficits and beliefs that discourage early detection and intervention.

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.

The Effect of Screening and Brief Intervention for Risky Drinking on Health Care Utilization in Managed Care Organizations

OBJECTIVE

We sought to estimate the effect of screening and brief intervention (SBI) for risky alcohol use on the health care utilization of risky drinkers in 4 managed care organizations.

RESEARCH DESIGN

A quasi-experimental group design was implemented in which 12 participating primary care clinics randomly were assigned to 1 of 3 study conditions. In one condition, physicians, physician assistants, and nurse practitioners delivered the brief intervention. In another condition, midlevel professionals (usually nurses) performed the brief intervention. In the third condition, SBI was not performed. Using administrative claims data, we estimated the effect of SBI on individual-level annual days of total and inpatient health care utilization; annual outpatient visits; annual emergency room visits; and annual visits related to alcohol, drug, or mental health conditions. Negative binomial regression models were used to control for other factors that may affect health care utilization.

RESULTS

Across all categories of care, the pre- to postintervention change in average health care utilization among risky drinkers in the intervention clinics was not significantly different from that of risky drinkers in the comparison clinics.

CONCLUSIONS

Our findings suggest that there is no effect of SBI on the health care utilization of risky drinkers in the year following the intervention. Although SBI does not appear to reduce health care utilization, previous studies find that it significantly reduces the alcohol consumption of risky drinkers. Because these reductions presumably improve patients' overall health and well-being, managed care organizations may still find it beneficial to implement SBI on a broad scale.
