Screening
for Alcohol Problems—An Update
The
prevalence of alcohol use disorders is significantly higher among
patients visiting a primary care practitioner than among the general
population (1,2).
For this reason, clinicians have the opportunity to
play a key role in detecting alcohol problems and in initiating
prevention or treatment efforts.
A variety of relatively brief screening
instruments are available for this purpose (3–5). These instruments do
not provide a diagnosis, but help identify patients who might benefit
from a more thorough assessment of their drinking behavior (6).
Following screening, the presence of an alcohol use disorder can be
confirmed using standard clinical diagnostic criteria. The success of
this approach has been demonstrated. In one study, 80 percent of
patients whose screening results were confirmed by a formal diagnosis of
alcohol dependence accepted referrals to alcoholism treatment programs
(7).
Patients should
be screened not only for alcohol use disorders, but also for drinking
patterns or behaviors that may place them at increased risk for
developing adverse health effects or alcoholism (i.e., risky drinking)
(5). Risky drinkers who have not yet become alcohol dependent often can
be treated successfully within the primary care setting (8).
This Alcohol
Alert presents information on selected screening instruments for use
with primary care patients as well as other patient populations among
whom alcohol use is either highly prevalent or hazardous.
Types of Instruments
Two types of
alcoholism-screening instruments are available. The first type includes
self-report questionnaires and structured interviews; the second type
includes clinical laboratory tests that can detect biochemical changes
associated with excessive alcohol consumption.
The value of a screening
instrument for measuring alcohol problems or other conditions is related
to its sensitivity and specificity. Sensitivity refers to a test’s
accuracy in identifying people who have an alcohol problem (i.e., people
with the condition test positive). Specificity refers to the test’s
effectiveness in identifying people who do not have an alcohol problem
(i.e., people without the disease test negative).
No screening
instrument is perfect. It is not possible to optimize both sensitivity
and specificity in the same screening instrument. The likelihood of over identifying
alcohol use disorders occurs with increased sensitivity
and the possibility of missing people who have an alcohol problem grows
with increased specificity. Despite these limitations, research supports
the use of formal screening instruments to increase the recognition of
alcohol problems (5,9).
Questionnaires
Screening
instruments vary in their ability to detect different patterns and
levels of drinking and in the degree of their applicability to specific
subpopulations and settings (2). This section compares features of some
of the most widely used screening questionnaires. Detailed information
is available at the NIAAA Web site ( http://www.niaaa.nih.gov
).
The CAGE
questionnaire (10) has been evaluated in several studies, showing
sensitivities ranging from 43 to 94 percent for detecting alcohol abuse
and alcoholism (5). CAGE is well suited to busy primary care settings
because it poses four straightforward yes/no questions that the
clinician can easily remember and requires less than a minute to
complete. However, the test may fail to detect low but risky levels of
drinking (5). In addition, CAGE often performs less well among women and
minority populations (11,12).
The performance
of CAGE can be improved by incorporating questions about the quantity
and frequency of drinking, as recommended by NIAAA in The
Physicians’ Guide to Helping Patients With Alcohol Problems (13).
A study found that the screening strategy suggested in the Physicians’
Guide effectively identified alcohol abuse and dependence in a general
population sample (14). The same approach also demonstrated better
sensitivity and similar specificity compared with CAGE alone among
African American patients in an urban emergency room (15).
The Alcohol Use
Disorders Identification Test (AUDIT) (16) also incorporates questions
about quantity and frequency of alcohol use. In contrast to CAGE, AUDIT
compares favorably with other instruments in detecting risky drinking,
but is less effective in identifying alcohol abuse and alcoholism
(5,17). Originally developed for primary care settings, AUDIT has proven
useful among medical and psychiatric inpatients, in emergency rooms
(17), and in the workplace (17–19). AUDIT is relatively free of gender
and cultural bias (11,17,20). In addition, it shows promise for
screening adolescents and older people, populations in which standard
screening instruments produce inconsistent results (12,17,21–23). The
major disadvantage of AUDIT is its length and relative complexity;
clinicians require training to score and interpret the test results (3).
Screening
pregnant women for alcohol use has become increasingly important in
light of new research showing that even low levels of prenatal alcohol
exposure can harm the fetus. Unfortunately, although approximately 20
percent of women consume some alcohol during pregnancy, maternal
drinking can be difficult to detect (24). At least two questionnaires
are available that are appropriate for pregnant women, both derived in
part from CAGE. T–ACE (25) takes approximately 1 minute to complete
and is more accurate than AUDIT for detecting current alcohol
consumption and risky drinking, as well as a history of past alcoholism;
however, it is less specific (24). The five-item TWEAK (26) performs
similarly to T–ACE (24) and can be used to detect a range of drinking
levels from moderate to high-risk consumption (27).
Alcohol
consumption plays a role in a large percentage of trauma incidents,
including motor vehicle crashes. RAPS4 is a four-item questionnaire
derived in part from TWEAK and AUDIT. In both primary care and emergency
room settings, RAPS4 showed consistently high sensitivity for detecting
alcoholism across gender and ethnic subgroups, although its utility for
screening for risky drinking or alcohol abuse has yet to be proven
(28,29).
Computer-Assisted
Screening. Computers have been widely and successfully used in
screening and in assisting alcoholism intervention (17,30). Studies have
found no significant difference in accuracy between computerized and
paper-and-pencil versions of AUDIT among inpatient alcoholics (31).
Similar results have been achieved with CAGE in the primary care setting
(31). In addition, small laptop computers have been used in large-scale
alcohol screening surveys. For example, in Audio Computer Assisted
Self-Interviewing (ACASI), a recorded voice asks questions that can be
answered by pressing a few keys. Advantages include ease of use for
respondents with poor literacy or computer skills, as well as increased
privacy, although the interviewer remains nearby to offer assistance if
necessary (32).
The Internet
provides an increasingly accessible, low-cost medium for screening and
brief intervention (30). A pilot web site incorporating AUDIT and other
alcohol history questions attracted more than 10,000 people during an
initial 172-day trial. Of 2,253 people who took the test, 89 percent had
scores suggesting harmful drinking or alcoholism, although 94 percent of
participants of the total sample had never been diagnosed (30). The
procedure is completely automated and self-administered.
Biological Markers
In contrast to
self-report questionnaires, clinical laboratory procedures provide
objective evidence of problem drinking. They are generally less
sensitive and specific than questionnaires, but are valuable for
corroborating results of interviews and questionnaires (33). The
accuracy of these markers is affected by various factors such as
nonalcoholic liver damage, use of medications or drugs, and by metabolic
disorders. Three widely used tests and one promising new marker are
described here.
Gamma-glutamyl
transferase (GGT) is the most commonly used biochemical measure of
drinking (33). Chronic drinking of 4 or more drinks per day for 4 to 8
weeks significantly raises levels of this blood protein, at least in
alcoholics (33). Four to five weeks of abstinence are usually required
for GGT levels to return to within normal range (33). The ability of
this test to detect long-term heavy drinking in the recent past makes
GGT useful for monitoring abstinence in recovering alcoholics. However,
nonalcoholic liver disease also can increase GGT levels, increasing the
likelihood of false-positive results.
Carbohydrate-deficient
transferrin (CDT) is another blood protein that increases in
concentration with heavy alcohol consumption (34). CDT values become
elevated substantially earlier (1 to 2 weeks) in response to prolonged
excessive drinking than conventional markers such as GGT (35). GGT and
CDT are approximately equal in their ability to identify alcoholism.
However, few conditions other than heavy drinking will elevate CDT
levels, decreasing the probability of false positives (35).
Disadvantages include lower sensitivity in women and adolescents, and
the high cost of the laboratory analysis (33).
Mean corpuscular
volume (MCV), an index of red blood cell size, increases with excessive
alcohol intake after 4 to 8 weeks (33). The sensitivity of MCV is too
low to justify its use as a single indicator (35). However, it has
higher specificity compared with other tests. MCV can detect evidence of
earlier drinking after a long period of abstinence. For this reason, it
is a poor indicator of recovery among alcoholics who have stopped
drinking (35).
Fatty acid ethyl
esters (FAEEs) show promise as markers of maternal drinking. FAEEs are
formed by the interaction of alcohol and natural fatty substances in the
body. They have been detected in samples of meconium (i.e., the waste
product of newborns). Some evidence suggests that analysis of FAEEs in
meconium may indicate timing of prenatal alcohol exposure (34).
Screening for Alcohol Problems—A Commentary by Raynard Kington,
M.D., Ph.D., Acting NIAAA Director, and Richard K. Fuller, M.D.,
Director, Division of Clinical and Prevention Research
National Alcohol
Screening Day (NASD) is a nationwide, one-day event that provides free
and confidential screening for alcohol problems. During NASD,
screening—along with public education and referral to treatment, when
necessary—occurs in a variety of health care and community settings,
including college campuses and military bases. This Alert describes
a number of questionnaires and medical tests that can be used in primary
care settings to screen individuals who have or who are at risk for
developing alcohol problems. We hope that the information provided here
will encourage practitioners to make the screening and referral that are
the centerpieces of NASD an ongoing part of their practice throughout
the year. Given the impact of heavy drinking on overall health and the
prevalence of patients in the primary care system who have an alcohol
use problem, screening and referral should be considered part of sound
clinical practice, rather than simply added patient services. More
information on screening is available at the National Institute on
Alcohol Abuse and Alcoholism Web site at http://www.niaaa.nih.gov/publications/instable.htm.

Alcohol Alert
National Institute on Alcohol Abuse and Alcoholism
No. 30 PH 359 October 1995
Diagnostic Criteria for Alcohol Abuse and Dependence
Diagnosis is the process of identifying and
labeling specific conditions such as alcohol abuse or dependence (1).
Diagnostic criteria for alcohol abuse and dependence reflect the consensus
of researchers as to precisely which patterns of behavior or physiological
characteristics constitute symptoms of these conditions (1). Diagnostic
criteria allow clinicians to plan treatment and monitor treatment
progress; make communication possible between clinicians and researchers;
enable public health planners to ensure the availability of treatment
facilities; help health care insurers to decide whether treatment will be
reimbursed; and allow patients access to medical insurance coverage (1-3).
Diagnostic criteria for alcohol abuse and dependence have
evolved over time. As new data become available, researchers revise the
criteria to improve their reliability, validity, and precision (4,5). This
Alcohol Alert traces the evolution of diagnostic criteria for
alcohol abuse and dependence through the current standards of the American
Psychiatric Association's Diagnostic and Statistical Manual of Mental
Disorders, Fourth Edition (DSM-IV) (6). For comparison, the criteria
found in the World Health Organization's International Classification
of Diseases, Tenth Revision (ICD-10) also are reviewed briefly,
although these are not often used in the United States (7).
Evolution of Diagnostic Criteria
Early Criteria
At least 39 diagnostic systems had been identified before
1940 (2). In 1941 Jlinek first published what is considered a
groundbreaking theory of subtypes of what was, until 1980, termed
alcoholism (2,8). Jellinek associated these subtypes with different
degrees of physical, psychological, social, and occupational impairment
(2,9).
Formulations of diagnostic criteria continued with the
American Psychiatric Association's publication of the Diagnostic and
Statistical Manual of Mental Disorders, First Edition (DSM-I), and Second
Edition (DSM-II) (10,11). Alcoholism was categorized in both editions
as a subset of personality disorders, homosexuality, and neuroses (2,12).
In response to perceived deficiencies in DSM-I and DSM-II,
the Feighner criteria were developed in the 1970's to establish a research
base for the diagnostic criteria of alcoholism (5,13). These criteria were
the first to be based on research rather than on subjective judgment and
clinical experience alone (5). Though designed for use in clinical
practice, they were primarily developed to stimulate continued research
for the development of even more useful diagnostic criteria (5). Several
years later, Edwards and Gross focused solely on alcohol dependence (8).
They considered essential elements of dependence to be a narrowing of the
drinking repertoire, drink-seeking behavior, tolerance, withdrawal,
drinking to relieve or avoid withdrawal symptoms, subjective awareness of
the compulsion to drink, and a return to drinking after a period of
abstinence (8)
The DSM Criteria
Researchers and clinicians in the United States usually
rely on the DSM diagnostic criteria. The evolution of diagnostic criteria
for behavioral disorders involving alcohol reached a turning point in 1980
with the publication of the Diagnostic and Statistical Manual of Mental
Disorders, Third Edition (14). In DSM-III, for the first time, the
term "alcoholism" was dropped in favor of two distinct
categories labeled "alcohol abuse" and "alcohol
dependence" (1,2,12,15). In a further break from the past, DSM-III
included alcohol abus e and dependence in the category "substance use
disorders" rather than as subsets of personality disorders (1,2,12).
The DSM was revised again in 1987 (DSM-III-R) (16). In
DSM-III-R, the category of dependence was expanded to include some
criteria that in DSM-III were considered symptoms of abuse. For example,
the DSM-III-R described dependence as including both physiological
symptoms, such as tolerance and withdrawal, and behavioral symptoms, such
as impaired control over drinking (17). In DSM-III-R, abuse became a
residual category for diagnosing those who never met the criteria for
dependence, but who drank despite alcohol-related physical, social,
psychological, or occupational problems, or who drank in dangerous
situations, such as in conjunction with driving (17). According to Babor,
this conceptualization allowed the clinician to classify meaningful
aspects of a patient's behavior even when that behavior was not clearly
associated with dependence (18).
The DSM was revised again in 1994 and was published as the
Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition
(DSM-IV) (6). The section on substance-related disorders was revised in a
coordinated effort involving a working group of researchers and clinicians
as well as a multitude of advisers representing the fields of psychiatry,
psychology, and the addictions (2). The latest edition of the DSM
represents the culmination of their years of reviewing the literature;
analyzing data sets, such as those collected during the Epidemiologic
Catchment Area Study; conducting field trials of two potential versions of
DSM-IV; communicating the results of these processes; and reaching
consensus on the criteria to be included in the new edition (2,19).
DSM-IV, like its predecessors, includes nonoverlapping
criteria for dependence and abuse. However, in a departure from earlier
editions, DSM-IV provides for the subtyping of dependence based on the
presence or absence of tolerance and withdrawal (6). The criteria for
abuse in DSM-IV were expanded to include drinking despite recurrent
social, interpersonal, and legal problems as a result of alcohol use
(2,4). In addition, DSM-IV highlights the fact that symptoms of certain
disorders, such as anxiety or depression, may be related to an
individual's use of alcohol or other drugs (2).
The ICD Criteria
While the American psychiatric community was formulating
its editions of diagnostic criteria for mental disorders, the World Health
Organization was developing diagnostic criteria for the purpose of
compiling statistics on all causes of death and illness, including those
related to alcohol abuse or dependence, worldwide (1,4,20). These criteria
are published as the International Classification of Diseases (ICD).
The first ICD classification of substance-related problems, published in
1967 in ICD-8 (21), classified what was then called alcoholism with
personality disorders and neuroses, as had DSM-I and DSM-II. In ICD-8,
alcoholism was a separate category that included episodic excessive
drinking, habitual excessive drinking, and alcohol addiction that was
characterized by the compulsion to drink and by withdrawal symptoms when
drinking was stopped (1).
Although ICD-9 (22,23) included separate criteria for
alcohol abuse and dependence, this revision defined them similarly in
terms of signs and symptoms (1). According to Babor, an important
assumption in ICD-9 was that alcohol use in the absence of dependence
"merits a separate category by virtue of its detrimental effects on
health" (1, p. 87).
The category of alcohol dependence was central to the
current revision, ICD-10 (1,2,7). Alcohol dependence is defined in this
classification in a way that is similar to the DSM. The diagnosis focuses
on an interrelated cluster of psychological symptoms, such as craving;
physiological signs, such as tolerance and withdrawal; and behavioral
indicators , such as the use of alcohol to relieve withdrawal discomfort
(1). However, in a departure from the DSM, rather than include the
category "alcohol abuse," ICD-10 includes the concept of
"harmful use." This category was created so that health problems
related to alcohol and other drug use would not be underreported (1).
Harmful use implies alcohol use that causes either physical or mental
damage in the absence of dependence (1).
Moving Toward Agreement Between Diagnostic Criteria
The DSM diagnostic criteria for psychiatric disorders are
the criteria primarily used in the United States. The ICD is an
international diagnostic and classification system for all causes of death
and disability, including psychiatric disorders (4). Earlier editions of
these two major diagnostic criteria dealing with alcohol abuse and
dependence were criticized for being too dissimilar (2). Therefore, the
DSM-IV and the ICD-10 were revised in a coordinated effort among
researchers worldwide to develop criteria that were as consistent with one
another as possible (1,2).
Although some differences between the two major diagnostic
criteria still exist, they have been revised by consensus as to how
alcohol abuse and dependence are best characterized for clinical purposes
(18). Clinicians, international health agencies, and researchers are now
better able to categorize people with alcohol dependence, abuse, and
harmful use to plan treatment, collect statistical data, and communicate
research results (18).
Diagnostic Criteria--A Commentary by
NIAAA Director Enoch Gordis, M.D.
The research community has long found standardized
diagnostic criteria useful. Such criteria provide agreement as to the
constellation of symptoms that indicate the alcohol dependence syndrome
and allow researchers all over the world to communicate clearly as to what
kinds of disorders are being studied.
Standardized diagnostic criteria are equally important and
useful to clinicians. In the alcohol field, there have been many different
ways by which clinical staff might arrive at a diagnosis--sometimes
differing among staff within the same program. Although the use of
standard diagnostic criteria may seem somewhat burdensome, it provides
many benefits: more efficient assessment and placement, more consistency
in diagnoses between and within programs, enhanced ability to measure the
effectiveness of a program, and provision of services to people who most
need them. As we move more and more into a managed health care arena,
third-party payors are requiring more standardized reporting of illnesses;
they want to know what conditions they are paying for and that these
conditions are the same from program to program. The standardized
diagnostic criteria presented in this Alert are based on the newest
research, have been developed based on field trials and extensive reviews
of the literature, and are continually revised to reflect new findings.
Although clinical judgment will always play a role in diagnosing any
illness, alcohol treatment programs that use standardized diagnostic
criteria will be in the best position to select appropriate treatment and
to justify their selection to third-party payors.
