Increasing emphasis has been placed on the detection and treatment of hazardous and harmful drinking disorders, particularly among patients who are seen in primary care settings. In this review, we summarize the epidemiology and health-related effects of hazardous and harmful drinking and discuss current methods for their detection and treatment. Hazardous drinking is defined as a quantity or pattern of alcohol consumption that places patients at risk for adverse health events, while harmful drinking is defined as alcohol consumption that results in adverse events (eg, physical or psychological harm). Prevalence estimates range from 4% to 29% for hazardous drinking and from less than 1% to 10% for harmful drinking. Data from several recent large prospective studies suggest that alcohol consumption in quantities consistent with hazardous or harmful drinking may increase risk for adverse health events, such as hemorrhagic stroke and breast cancer. Existing screening instruments, such as the Michigan Alcoholism Screening Test (MAST) or the CAGE questionnaire, while excellent for detecting alcohol abuse or dependence, should not be used alone to screen for hazardous and harmful drinking. The Alcohol Use Disorders Identification Test (AUDIT) is currently the only instrument specifically designed to identify hazardous and harmful drinking. Treatment of these disorders in the form of brief interventions can be successfully accomplished in primary care settings, as demonstrated by a number of well-conducted randomized trials. Given its proven efficacy in the primary care setting, we recommend routine application of this treatment approach.

Alcohol use disorders (AUDs) are a recognized cause of significant morbidity and mortality in the US population.1 These disorders are heterogeneous and include severe problems, such as alcohol abuse or dependence, as well as less severe disorders, often referred to as heavy, hazardous, or harmful drinking. Although alcohol abuse and dependence have historically received the greatest attention, increasing emphasis has been placed on the detection24 and treatment5,6 of less severe AUDs, particularly in primary care settings.26 This change in focus has occurred in part because of reports that heavy, hazardous, and harmful drinking are more common and may be more responsive to treatment2,4 than alcohol abuse or dependence. In this article, we review the epidemiology and health-related effects of these drinking disorders and summarize current methods for their detection and treatment.

Table 1 lists the various categories of AUDs and their definitions as used in this review. These categories reflect the clinical reality that drinking problems occur over a broad continuum, ranging from alcohol consumption that can result in profound physical and psychological impairment (alcohol dependence) to less severe disorders (heavy or hazardous drinking).

Table Graphic Jump LocationTable 1. Alcohol Use Disorder Definitions*

Heavy drinking is defined as a quantity of alcohol consumption that exceeds an established threshold value. The National Institute of Alcohol Abuse and Alcoholism sets this threshold at more than 14 drinks per week for men (or >4 drinks per occasion); more than 7 drinks per week for women (or >3 drinks per occasion); and more than 7 drinks per week for all adults 65 years and above.7 Individuals whose drinking exceeds these guidelines are thought to be at increased risk for adverse health events.2,7,8

Hazardous drinking is defined as a quantity or pattern of alcohol consumption that places individuals at risk for adverse health events9 and is recognized by the World Health Organization (WHO) as a distinct disorder. The quantity or pattern of alcohol consumption that constitutes hazardous drinking is also typically specified by setting threshold values for an individual's average number of drinks consumed per week or per occasion. For example, in a recent study10 that examined the efficacy of the Alcohol Use Disorders Identification Test (AUDIT),9 hazardous drinking was defined as an average consumption of 21 drinks or more per week for men (or ≥7 drinks per occasion at least 3 times a week), and 14 drinks or more per week for women (or ≥5 drinks per occasion at least 3 times a week).

Because hazardous and heavy drinking are similarly defined (ie, a quantity or pattern of alcohol consumption that exceeds a specific threshold and may increase risk for adverse health events), we will use 1 term, hazardous drinking, to define this type of drinking disorder.

Harmful drinking is defined as alcohol consumption that results in physical or psychological harm. This disorder is also recognized by the WHO9 and is defined by criteria of the International Classification of Diseases, 10th Revision (ICD-10),11 which include (1) clear evidence that alcohol is responsible for physical or psychological harm, (2) the nature of the harm is identifiable, (3) alcohol consumption has persisted for at least 1 month or has occurred repeatedly over the previous 12-month period, and (4) the individual does not meet the criteria for alcohol dependence.

Prevalence estimates for hazardous and harmful drinking are shown in Table 2 and Table 3, along with information regarding the various study settings, populations, and definitions used to classify these disorders. Most of these studies also determined prevalence rates for alcohol dependence, and these data are reported for purposes of comparison. Unless noted, reported prevalence estimates for individual drinking disorders are mutually exclusive.

Hilton12 surveyed more than 5000 adults in 1984 to determine the prevalence of alcohol disorders among US adults (Table 2). Hazardous drinking was reported by 18% of men and 5% of women, whereas prevalence rates for harmful drinking were 10% and 4% for men and women, respectively. In contrast, 7% of men and 3% of women had problematic drinking disorders and would likely have met the current diagnostic criteria for alcohol dependence. These prevalence estimates are not mutually exclusive. Among men classified as hazardous drinkers, 36% met the criteria for harmful drinking and an additional 27% were found to have problematic drinking disorders, whereas among women classified as hazardous drinkers, 44% fulfilled the criteria for harmful drinking and an additional 31% were classified as problematic drinkers.

Archer and Grant13 analyzed results from the 1988 National Health Interview Survey (NHIS), a population-based study of more than 40,000 US adults, and found that 54% of the participants reported current consumption of alcohol. Among current drinkers, 16% met the criteria for alcohol abuse or dependence (9% of the population studied), and 24% reported drinking at hazardous levels (13% of the population studied). In the NHIS, approximately 50% of all current drinkers who were classified as having alcohol abuse or dependence also fulfilled the criteria for hazardous drinking. In a separate study of all NHIS participants (N=41,128), Grant14 determined the prevalence of alcohol dependence and harmful drinking using different diagnostic criteria. In this study, prevalence rates for alcohol dependence and harmful drinking were 7% and 0.3%, respectively. Finally, Dawson et al15 determined that among adults surveyed in the 1992 National Longitudinal Alcohol Epidemiologic Study (N=42,862), 14% of men and 4% of women reported drinking at hazardous levels.

McMenamin16 screened 611 primary care patients aged 30 to 69 years for alcohol disorders using a self-administered questionnaire that measured quantity and frequency of consumption as well as alcohol-related problems (Table 3). Six percent of the subjects met the criteria for alcohol abuse or dependence and 15% were classified as hazardous drinkers. Adams et al8 screened more than 5000 older adults aged 60 years and above in 22 primary care practices with standard quantity-frequency questions and the CAGE questionnaire. Fifteen percent of men and 12% of women were classified as hazardous drinkers, and 9% and 3% of men and women, respectively, screened positive for dependent drinking. In this study, 14% of all hazardous drinkers also met the study criteria for alcohol dependence. Piccinelli et al10 determined the prevalence of hazardous, harmful, and dependent drinking among 482 primary care patients using the AUDIT and ICD-10 criteria as the criterion standard. Hazardous drinking was reported by 29% of men and 4% of women. The prevalence of harmful alcohol consumption was 7% among men and less than 1% in women, whereas fewer than 2% of subjects (all men) were alcohol dependent.

Volk et al17 employed the AUDIT and the Alcohol Use Disorder and Associated Disabilities Interview Schedule as the criterion standard to ascertain the prevalence of hazardous, harmful, and dependent drinking among 1333 primary care patients with different racial and ethnic backgrounds. Prevalence rates for hazardous drinking ranged from 4% to 5% to 9% for white, African American, and Mexican American men, respectively, and from 4% to 3% to 2% for women in each of the 3 subgroups, (R. J. Volk, PhD, written communication, November, 1998). In contrast, prevalence estimates for harmful drinking were 1% or less across the 3 subgroups.17 The most common drinking disorder encountered was alcohol dependence,17 with prevalence rates that ranged from 11% to 12% to 14% among African American, Mexican American, and white men, and from 7% to 6% to 5% for women among the 3 subgroups (R. J. Volk, PhD, written communication, November 1998).

These data suggest that hazardous drinking is common among US adults and medical outpatients, with prevalence estimates varying from 4% to 29%. The wide variation in reported prevalence for hazardous drinking is probably caused by differences in the way the disorder was defined and lack of mutually exclusive diagnostic criteria. Prevalence rates for harmful drinking, in contrast, ranged from 0.3% to 10%. Although harmful drinking is thought to be more prevalent than alcohol dependence,2 published prevalence estimates do not support this view. One potential explanation for this unexpected finding is that the current diagnostic criteria (ICD-10) for harmful drinking may have excellent specificity, but may not be sufficiently sensitive to detect less severe manifestations of alcohol-related problems. Demonstrating clear evidence of physical (eg, gastrointestinal hemorrhage) or psychological (eg, depression) harm may be difficult, except in severe cases (ie, alcohol dependence).

In general, these studies support recommendations that call for increased attention to less severe AUDs, particularly hazardous drinking. Additional studies are needed to further define the extent and spectrum of hazardous and harmful drinking in primary care settings. To promote effective comparisons, future investigations should use similar diagnostic criteria and ensure that mutually exclusive prevalence estimates are reported for the entire spectrum of drinking disorders.

Alcohol intake of more than 6 drinks per day increases the risk for numerous adverse health events.1820 In contrast, the adverse effects of alcohol consumption in quantities above 2 (but <6) drinks per day have received less attention. Most patients drinking at hazardous or harmful levels would likely sustain this intermediate level of alcohol exposure. Accordingly, we reviewed large (N>1000) observational cohort studies published between 1988 and 1998 that provided risk estimates for the independent effect of alcohol intake across this range of exposure on 3 outcomes: all-cause mortality, stroke, and breast cancer. Although the number and type of potential confounders examined in these studies2143 varied considerably, age and smoking status were included in all analyses.

At least 13 large prospective studies2133 have evaluated the relationship between alcohol consumption and all-cause mortality. In general, these studies found either a U- or J-shaped association between alcohol consumption and all-cause mortality for both sexes, where categories of exposure ranged from none to 6 drinks or more per day. Statistically significant risk estimates were reported in 6 studies,21,23,24,27,31,33 (relative risk [RR] range, 1.2-2.2), whereas 2 investigations25,26 found that alcohol exposure of 2 drinks or more a day significantly lowered overall mortality. These estimates fail to provide important information about cause-specific mortality; for example, deaths from cardiovascular disease were on average lower across these exposure categories,24,26,28,29 while mortality rates from various cancers21,24,27,29,31,32 and fatal injuries24,29,31 were substantially increased.

Five recent large prospective studies3438 examined the association between alcohol consumption and stroke. Two studies34,37 found increased risk for ischemic stroke among subjects who drank 2 drinks or more per day; however, in only 1 was statistical significance demonstrated (RR, 2.0).37 Of the remaining 3 studies, 1 found no effect,35 while 236,38 found nonsignificant protective effects. Alcohol consumption of 2 drinks or more per day, however, may increase the risk for hemorrhagic stroke. Statistically significant increases in risk (RR range, 3.1-3.9) were reported by 2 studies36,37 that examined the relationship between alcohol intake and hemorrhagic stroke.

Drinking 3 drinks or more per day may increase the risk for breast cancer, as demonstrated in 5 large prospective studies.3943 Statistical significance was demonstrated in 2 of these investigations40,43 (RR range, 1.6-3.3), whereas in 3 studies,39,41,42 nonsignificant increases in risk were found. Given the public health importance of this cancer, women drinking 3 drinks or more per day should be counseled to reduce their alcohol intake, even though a causal connection has not been definitively established between alcohol consumption and breast cancer.

These data suggest that alcohol-related morbidity and mortality may occur at doses below those typically considered diagnostic of alcohol abuse and/or dependence. Alcohol consumption of 2 drinks or more per day may also increase the risk for the development of hypertension,44,45 traumatic injuries,46,47 and adverse drug-alcohol interactions,48,49 and may impair an individual's social and occupational functioning. The absolute magnitude of this effect, however, can vary widely by outcome. Additional research is needed to define the health-related effects of hazardous and harmful drinking in primary care populations.

The Michigan Alcoholism Screening Test (MAST)50 and the CAGE questionnaire51 are 2 standardized instruments commonly used to detect drinking disorders in primary care settings. The MAST was originally developed as an instrument to detect alcohol dependence and contains 24 questions that inquire about patients' drinking behavior and their perceptions of adverse consequences or personal concerns that stem from alcohol consumption. Studies evaluating the MAST have found it to have good performance in detecting alcohol dependence, with sensitivities that range from 90% to 98% and specificities between 57% and 82%.52,53 The MAST is not very sensitive, however, in identifying hazardous or harmful drinkers. For example, Cherpitel54 demonstrated that a brief (10-item) version of the MAST had a specificity of 98% but a sensitivity of only 31% for identifying harmful drinking as defined by the ICD-10 criteria.

The CAGE questionnaire is perhaps the best-known screening instrument for alcoholism.51 The 4 CAGE questions are: "Have you ever felt you should cut down on your drinking? Have people annoyed you by criticizing your drinking? Have you ever felt bad or guilty about your drinking? Have you ever had a drink first thing in the morning to steady your nerves or get rid of a hangover (eye-opener)." The National Institute of Alcohol Abuse and Alcoholism recommends using the CAGE questionnaire to screen every patient who drinks alcohol and considers 2 affirmative responses a positive indication for alcoholism.7 Using the DSM-III or DSM-III-R criteria as the criterion standard, a CAGE questionnaire score of 2 or higher has a reported sensitivity of 73% to 81% for detecting alcohol abuse or dependence, while specificity ranges from 89% to 96%.5557

The ability of the CAGE questionnaire to detect hazardous drinking in the primary care setting has been examined. Adams et al8 administered both the CAGE and standard quantity-frequency questions to more than 5000 patients aged 60 years and above. Nine percent of men and 3% of women were determined to be positive for hazardous drinking when a cutoff score of 2 was used, whereas 20% of men and 9% of women were determined to be positive using a cutoff score of 1 or higher.8 Comparison of CAGE questionnaire responses with standard quantity-frequency responses revealed that the CAGE questionnaire had low sensitivity (14%-40%) but high specificity (96%-97%) for detecting hazardous drinkers. Changing the CAGE questionnaire cutoff score to 1 improved the sensitivity (31%-63%) at the cost of reduced specificity (89%-92%). The authors concluded that the CAGE questionnaire was not a clinically useful tool when used alone to exclude the possibility of a hazardous drinking disorder.

The MAST and CAGE questionnaire share important limitations as screening tools for the detection of hazardous and harmful drinking. First, the instruments do not provide information about the quantity, frequency, or pattern of patients' alcohol consumption. Second, neither test discriminates between current and past drinking problems. Finally, both instruments were developed and standardized among patients with established alcohol dependence and were not intended to identify less severe disorders, such as hazardous or harmful drinking.

The recently developed AUDIT,58,59 in contrast, seeks to detect a broad spectrum of alcohol disorders that include hazardous and harmful drinking as well as alcohol dependence. The AUDIT was designed by the WHO as part of a worldwide collaborative effort to develop techniques for the identification and treatment of persons with current hazardous and harmful drinking disorders in primary care settings. The AUDIT (Table 4) consists of 10 questions and measures average quantity and frequency of consumption, the presence or absence of binge drinking, dependence symptoms, and alcohol-related problems. Each question is scored on a scale from 0 to 4, and a score of 8 or higher is typically considered a positive indication of an AUD.

Table Graphic Jump LocationTable 4. The Ten-Item AUDIT* Questionnaire

The validity of the AUDIT has been determined in a variety of clinical settings.9,10,17,54,5964 In the original population59 from which the AUDIT was derived (N=1888), 36% of subjects were classified as nondrinkers (total abstainers or reported ≤3 drinking occasions per year and had never been treated for an alcohol problem), 48% were classified as drinkers (reported ≥4 drinking occasions per year and had never received treatment for a drinking problem), and 16% were categorized as alcoholic (previously diagnosed as alcoholic or had prior treatment, or were currently seeking treatment for an alcohol-related disorder). A cutoff score of 8 on the AUDIT had a sensitivity and specificity of 87% and 81% for harmful drinking and 96% and 98% for hazardous drinking, respectively.59

Piccinelli et al10 determined the properties of the AUDIT in screening primary care patients for hazardous, harmful, and alcohol dependence disorders. The AUDIT performed well, with areas under the receiver operating characteristic curve of 0.92 for hazardous drinking (95% confidence interval [CI], 90%-93%), 0.90 for harmful alcohol consumption (95% CI, 88%-92%), and 0.91 for alcohol dependence (95% CI, 88%-94%). Using a score of 5 or higher as a positive indicator, the test had a sensitivity of 84% and a specificity of 97% for detecting these combined drinking disorders. The positive predictive value of the test (ie, the probability that an individual with a score of 5 or higher actually has a drinking disorder) was 60% and was estimated to be as high as 81% in a population in which the prevalence of AUDs was 50%.10 Further analysis found that just 5 items of the AUDIT performed with acceptable operating characteristics. The researchers recommended that the shortened 5-item AUDIT be used to screen patients for alcohol problems. Additional data regarding the performance of the shortened instrument, however, are lacking.

Steinbauer et al60 determined the ability of the AUDIT, CAGE questionnaire, and a self-administered version of the MAST to detect alcohol abuse or dependence among 1333 ethnically diverse primary care patients. The AUDIT demonstrated significantly better operating characteristics across a variety of clinically pertinent subgroups (eg, women, African Americans, and Mexican Americans) compared with the CAGE questionnaire and the self-administered MAST.

Several studies6163 have determined the validity of the AUDIT using DSM-III and DSM-III-R criteria as the reference standard. These investigations provide useful information on the ability of the AUDIT to detect alcohol abuse or dependence. Because the DSM-III and DSM-III-R criteria do not recognize hazardous or harmful drinking as distinct disorders, these investigations cannot provide data on the ability of the AUDIT to detect these less severe drinking disorders. Additional studies are needed to determine the accuracy of the AUDIT in detecting hazardous and harmful drinking disorders. Appropriate reference standards would include the ICD-10 criteria for harmful drinking and operational criteria for hazardous drinking (eg, defining an explicit quantity, frequency, or pattern of alcohol consumption). An alternative approach, as described below, is to determine the predictive validity of the instrument.

Conigrave et al64 investigated the capacity of the AUDIT to predict future alcohol-related harm. In this study, 330 participants were evaluated using the AUDIT at baseline and received follow-up at 3 years. Hazardous drinkers (AUDIT scores ≥8 at baseline) were more likely to experience social problems from drinking (60% vs 10%, P<.01), mental disorders (73% vs 42%, P<.01), and acute hospitalization (RR, 1.5; P<.05) compared with nonhazardous drinkers over the 3-year period.64 These results suggest that hazardous drinking is predictive of subsequent alcohol-related morbidity.

Regular screening for AUDs, including hazardous and harmful drinking as well as alcohol abuse and dependence, is indicated in the primary care setting. A thorough alcohol history that includes current (and past) quantity, frequency, and pattern of alcohol consumption should be obtained for all patients. The CAGE questionnaire and MAST, despite their limitations for detecting hazardous or harmful drinking, can successfully identify many patients with alcohol abuse or dependence and can be readily administered. The AUDIT may represent the most comprehensive method for identifying patients with hazardous, harmful, abuse, or dependence disorders. Additional studies are needed, however, to demonstrate the validity and utility of this instrument in primary care settings.

The MAST, CAGE, and AUDIT questionnaires can be self-administered or administered by physicians or other health care providers. The amount of time required to administer the MAST, CAGE, and AUDIT instruments varies from 5 minutes to less than 1 minute.

Additional history is required from patients who have positive responses to quantity-frequency questions or positive results on standardized screening instruments, and from those suspected of having an alcohol disorder regardless of their test scores. Additional questions should be asked to confirm (or exclude) a diagnosis of alcohol abuse or dependence (Table 1). Establishing the presence of physical or psychological harm in the absence of alcohol abuse or dependence indicates the presence of harmful drinking. Finally, a diagnosis of hazardous drinking is established when a patient reports a quantity or pattern of alcohol consumption that exceeds a defined threshold and when harmful consumption, abuse, and dependence disorders have been excluded.

Establishing a treatment plan is the next appropriate step in the management of patients with hazardous or harmful drinking disorders. Brief intervention represents the one form of treatment for hazardous or harmful drinking that has been demonstrated to be effective and thus appropriate for use in primary care settings. A brief intervention "is a short counseling session focused on helping a person change a specific behavior,"65 employs counseling techniques that are within the skill level of primary care physicians, and can be performed in the course of a brief office visit. These techniques have been elucidated in the FRAMES acronym: feedback about behaviors, indicating the patient's responsibility for changing their behavior, giving patients specific advice on how behavior should be changed, give patients' a menu of options on how to change their behavior, approaching patients with empathy, and supporting patients' self-efficacy.66

Bien et al67 performed a meta-analysis of 32 controlled studies of brief interventions published between 1977 and 1993. These studies were conducted in a variety of settings, including generalist and specialist physicians' offices, inpatient medical wards, alcohol treatment programs, and non–health care settings.67 Most studies (15/19) showed that brief interventions were more effective than no treatment, while the remainder demonstrated no difference.

In a more recent meta-analysis, Wilk et al6 examined 12 randomized controlled trials of brief interventions, 8 of which were conducted in outpatient settings.6875 These authors selected studies that enrolled more than 30 subjects, included a control (nonintervention) group, and incorporated only brief intervention therapy.6 Enrolled subjects included heavy drinkers who reported drinking 21 to 35 drinks per week; however, patients with "alcohol dependence" and "alcoholism" were specifically excluded in only 6 studies. The interventions employed in these studies generally lasted from 10 to 15 minutes, and most were administered over multiple visits.

Self-reported alcohol consumption was the primary outcome measure in 9 of the 12 studies, whereas 2 studies each ascertained the number of sick days, change in liver enzyme levels, or mortality.6 Among the 8 studies reporting drinking outcomes that allowed calculation of a pooled odds ratio, the results demonstrated a beneficial effect (pooled odds ratio, 1.95; 95% CI, 1.66-2.30).6972,7678 Of the 8 outpatient-based studies,6875 5 showed a beneficial effect.68,69,7173 Potential factors such as sex, intensity of counseling, and intervention setting (inpatient vs outpatient) were not significantly associated with any of the primary outcomes.6

Among the published trials of brief intervention therapy, 5 randomized controlled trials71,72,74,75,78 focused on outpatient settings and enrolled hazardous and harmful drinkers, while generally excluding those with alcohol dependence. Three of the trials showed brief interventions to be effective,71,72,78 while 274,75 found no significant effect.

Project TrEAT (Trial for Early Alcohol Treatment)78 represents the first large-scale clinical trial to evaluate the efficacy of brief intervention techniques in the United States. In this trial, Fleming et al78 determined the efficacy of a brief intervention in 17 community-based primary care practices in Wisconsin. The intervention consisted of 2 brief counseling visits scheduled 1 month apart. The intervention protocol included a scripted workbook that contained feedback regarding current health behaviors, with a review of the prevalence of and health effects associated with hazardous and harmful drinking. The workbook also included a worksheet on drinking cues and a drinking diary. Each physician visit was followed 2 weeks later by a telephone call from the clinic nurse. Patients in the control group received a health booklet on general health issues and were instructed to address any health concerns in their usual manner. All patients received follow-up at 6 and 12 months.

In this study,78 "problem drinkers" were defined as "men who drank more than 14 drinks per week (168 g of alcohol) and women who drank more than 11 drinks per week (132 g of alcohol)." Patients were excluded if they had received alcohol treatment or reported alcohol withdrawal symptoms in the previous 12 months, had been advised by their physician to change their alcohol consumption in the previous 3 months, or drank more than 50 drinks per week. More than 17,695 patients were screened and 774 (4%) met the inclusion criteria. Compared with baseline values, the brief intervention group experienced statistically significant reductions in 7-day alcohol consumption at 1 year relative to controls (19.1-11.5 vs 18.9-15.5 drinks; P<.001), as well as in the mean number of binge drinking episodes during the previous 30 days (5.7-3.1 vs 5.3-4.2 binges; P<.005) and the percentage of subjects drinking excessively in the previous 7 days (47.5%-17.8% vs 48.1%-32.5%; P<.001). In addition, men in the intervention group experienced significantly fewer total hospital days than those in the control group (178 vs 314; P<.001).

Studies of treatment interventions for hazardous and harmful drinkers in primary care settings demonstrate that brief interventions may effectively decrease alcohol consumption, improve liver function (among patients with previously elevated liver enzyme levels), and decrease the use of certain health services.6,67,78 Brief interventions appear to be equally effective in men and women, and efficacy may be enhanced when more than 1 session is administered.6 Despite these encouraging results, many critical questions remain regarding the effectiveness of brief interventions. First, since most studies report outcomes for 6 to 12 months, longer-term demonstration of the impact of these interventions is needed. Second, although the interventions were generally similar across these studies, the specific content and frequency of application varied considerably. Thus, the ideal intervention that can be generally applied in a variety of settings is unknown. Third, the need for repeated booster sessions over time has not been explored. Finally, more detailed assessments of long-term outcomes, such as sustained decreases in alcohol consumption, reduction in the progression of patients to more severe alcohol disorders (eg, alcohol dependence), and the overall cost-effectiveness of these approaches, should be established. Despite these questions, the current literature supports brief intervention therapy as a useful approach for primary care providers in caring for hazardous and harmful drinkers.

Existing epidemiologic data indicate that less severe drinking disorders, particularly hazardous alcohol consumption, are common in primary care settings. Recent large prospective studies2143 also suggest that alcohol consumption above 2 drinks per day may contribute to adverse health events, such as hemorrhagic stroke and breast cancer. These data support the recommendations of several national organizations2,3,7 that call for primary care physicians to take an active role in the identification and treatment of patients with hazardous and harmful drinking disorders. Future research is needed to further define the extent of these disorders and to identify potential subgroups at risk for hazardous and harmful drinking in primary care. Studies are also needed to more carefully define the spectrum of health-related effects associated with these disorders and to include outcomes, such as quality of life, effects on chronic medical conditions (eg, hypertension and diabetes mellitus), and the use of health services.

Routine screening for hazardous and harmful drinking is recommended for all primary care patients. Although the most effective screening method remains uncertain, physicians are advised to obtain a detailed alcohol history that includes questions on the quantity, frequency, and pattern of patients' alcohol consumption. Existing instruments such as the MAST or CAGE questionnaire, while excellent for detecting alcohol abuse or dependence, should not be used alone to screen for hazardous or harmful drinking. The AUDIT is currently the only instrument specifically designed to identify hazardous and harmful drinking. Additional studies are needed, however, to determine the ability of the AUDIT to correctly identify these disorders, particularly among diverse age, socioeconomic, and ethnic groups. Regardless of the specific method used to screen, physicians should familiarize themselves with various diagnostic criteria (Table 1) so that a diagnosis can be definitively established among patients suspected of having an alcohol disorder.

Finally, a number of well-conducted randomized trials have demonstrated the efficacy of brief interventions in the treatment of hazardous and harmful drinking in primary care settings. This treatment approach has been shown to significantly reduce alcohol consumption among treated patients. Additional research is needed, however, to demonstrate that brief interventions can decrease morbidity and mortality over longer periods (ie, >12 months) and have a favorable impact on other clinically relevant outcomes. Several excellent resources are available3,7,79 to assist physicians in implementing brief interventions in their practices. We recommend routine application of this treatment approach in the primary care setting, given its low cost and proven efficacy in reducing alcohol consumption and likely efficacy in improving health-related outcomes.
