Extent of the problem and risk factors

Alcohol problems in older adults aged 65 years or over, in the United Kingdom and internationally, have risen steadily over the past decade. These are a common but underdiagnosed and under-recognized problem. A UK survey in 2008 found that 21% of men and 10% of women aged 65 years and over reported drinking more than four and three units of alcohol respectively on at least one day per week (National Health Service Information Centre, 2010). A recent Royal College of Psychiatrists Report (2011) cited research that showed there has been a rise in the number drinking over weekly recommended limits by 60% in men and 100% in women between 1990 and 2006 with the number of people aged over 65 years requiring treatment for a substance misuse problem, set to more than double between 2001 and 2020, all of which points to a significant public health problem both now and in the future (National Health Service Information Centre, 2009).

There has been a significant rise recently in alcohol-related deaths, particularly in older males in the United Kingdom (Office for National Statistics, 2012) and among older adults across Europe (Hallgren et al., Reference Hallgren, Hogberg and Andreasson2010). In spite of the level of alcohol-related harm in this population and the need for research and intervention, public health initiatives related to alcohol use disorders often focus on younger age groups, with problems in older adults left under-detected or misdiagnosed (O’Connell et al., Reference O’Connell, Chin, Cunningham and Lawlor2003). A review of literature in this area concluded that two-thirds of alcohol problems in older adults remain undetected by physicians (Beullens and Aertgeerts, Reference Beullens and Aertgeerts2004). In the United Kingdom, the Royal College of Psychiatrists (RCPsych; 2011) Older Persons Substance Misuse working group published a report called Our Invisible Addicts (College Report CR165). They reported that older adults present with complex patterns of alcohol misuse interacting with the misuse of prescribed or over the counter medications. Importantly, they emphasized that one-third of older adults with alcohol use disorders develop these in later life.

Numerous triggers can initiate heavy drinking in later life. These include bereavement, mental stress, physical ill health, loneliness and social isolation, loss of occupation or income, disability or decline in functioning, boredom, anxiety, insomnia, family conflict, low self-esteem, sensory deficits, poor mobility, and cognitive impairment. (Alcohol Concern, 2002; Dar, Reference Dar2006). Other risk factors identified in older adults include being male, being of a higher social class, being a widower or divorced older man, or married older woman, experiencing social exclusion or homelessness, and genetic factors (Cooper et al., Reference Cooper, Arber, Fee and Ginn1999). In addition, a complex two-way relationship between stressors and drinking behavior in older adults has been reported (Brennan et al., Reference Brennan, Schutte and Moos1999).

Older adults may be unaware that recommended amounts of alcohol consumption reduce with age. Retirement has been reported as a time of life associated with increased alcohol consumption, although whether retirement itself is the causal factor has not been clearly identified (Adams et al., Reference Adams, Barry and Fleming1996). Gaining an understanding of this, as well as the risk factors in older adults for harmful drinking, will allow better understanding of the problem and a more appropriately targeted approach.

Benefits of detecting and treating

The incidence of alcohol use disorders in older adults is high enough to justify routine enquiry, especially as older adults are particularly vulnerable to the adverse effects on health and quality of life of alcohol (Dar, Reference Dar2006). Potential benefits of treating alcohol use disorder in this group include improved health, reduced rates of associated illnesses, reduced risk of falls and accidents, and more satisfying relationships. Reducing alcohol intake leads to a marked improvement in cognitive functioning in older adults without dementia (Brandt et al., Reference Brandt, Butters, Ryan and Bayog1983).

The Invisible Addicts report (RCPsych, 2011) recommends screening every person aged over 65 years as part of a routine health check and makes a call for separate guidance for older adults about safe drinking limits with a suggested maximum of 11 units per week for men and seven units per week for women. It refers to a paucity of research and evidence for treatment interventions, and services relating to the management of substance use disorders in older adults however also report that available studies have shown that older adults can and do benefit from treatment and in some cases have better outcomes than younger people and may remain in treatment for longer. For example, a study from Camden and Islington Alcohol Support Association (CASA), older persons’ service in North London, found that 72% of older adults showed improved self-care and psychosocial functioning following alcohol reduction treatment (Taber, Reference Taber2001), and another study (Rao, Reference Rao2013) reported that 38% of older adults with alcohol-related problems referred to community mental health teams achieved abstinence from alcohol or controlled drinking at six-month follow-up.

Older adults may benefit from psychological treatments, including social approaches, family therapy interventions, and cognitive-behavioral approaches (Alcohol Concern, 2002). Fleming et al. (Reference Fleming, Manwell, Barry, Adams and Stauffacher1999) demonstrated that two 10–15 minute counseling sessions that included advice, education, and contracting using a workbook resulted in a 34% reduction in seven-day alcohol use, a 47% reduction in mean number of binge-drinking episodes during a 12-month follow-up period compared with pre-intervention levels of alcohol consumption, and a 62% reduction in the percentage of older adults drinking more than 21 drinks per week.

There may be less pressure for an older individual to give up or reduce alcohol intake as they may have little or no pressure to work and experience fewer family responsibilities. It has been suggested that a harm reduction model may be a better conceptual fit for older at-risk drinkers who may not see their drinking as an addiction requiring total abstinence in the way that a 12-step program conceptualizes at-risk drinking (Lee et al., Reference Lee, Mericle, Ayalon and Arean2009). Therefore, it may be that effective treatment of older adult drinking will require the development of a different conceptual framework.

With accumulating evidence supporting the effectiveness of treating alcohol use disorders in older adults, there is a value of developing effective screening tools to identify such issues, as well as developing age appropriate interventions and services.

Barriers to detection and treatment

Notwithstanding good evidence for effective interventions, there are numerous barriers to detection and treatment of alcohol misuse disorders in older adults (Table 1).

Table 1. Barriers to detection of alcohol misuse problems in older adults

A major barrier refers to societal myths that state that older adults are unable to change their habits or should not be denied something, which may be felt to be their only pleasure, particularly if they feel the person may not have long to live. Inadvertent age discrimination may also lead to reluctance by alcohol services to treat older adults who may therefore have less access to services. There is a need for development of age appropriate services (Rao, Reference Rao2011). There is also a particular call for public health campaigns specifically targeting older adults as research shows that older adults are one of the least well-informed groups when asked about alcohol units, and are also the least likely to know about the risks relating to alcohol consumption (Lader and Steel, Reference Lader and Steel2010).

Hallgren et al. (Reference Hallgren, Hogberg and Andreasson2010) have suggested that alcohol consumption in older adults is a subject which has until recently fallen between the gaps of aging research on the one hand, and alcohol and drug research and policy on the other. It is disappointing that in spite of identifying the need to research the consequences of lower levels of alcohol consumption on the physical and psychosocial health of older individuals and the need to expand or modify existing tests (Fink et al., Reference Fink, Hays, Moore and Beck1996), little progress has been made in this area. Most of the available research originates in the United States and a proportion of this is limited to white males in US Veterans hospitals (RCPsych, 2011).

Healthcare practitioners’ awareness and attitude toward alcohol use in older adults are also an issue. (Dar, Reference Dar2006). Professionals may not be aware of the extent of the problem or may have had inadequate training about detection and interventions and importantly may feel awkward about asking older patients about their alcohol consumption. In one study, a third of included patients with an alcohol problem had not had an alcohol history taken (Mears and Spice, Reference Mears and Spice1993). Professionals may also feel that they do not have sufficient time to carry out screening or intervention (Yarnall et al., Reference Yarnall, Polla, Ostbye, Krause and Michener2003). This suggests that development of validated short screening measures is needed.

Emerging evidence from available guidance describes the concept of “mainstreaming,” meaning that staff in whatever setting should be equipped to deliver integrated care for this group (Rao and Shanks, Reference Rao and Shanks2011). This has implications for training and development of the workforce. Rao and Shanks described a training program within South London and Maudsley which equips professionals working on mental health of older adults, teams with skills to screen for the presence of alcohol problems, establish therapeutic relationships, assess needs and implement low-intensity interventions, and recognize those patients with complex needs who require referral to specialist dual diagnosis services for higher intensity interventions. This has resulted in a shift in culture among staff. The concept of “if you don't think about it then you won't see it” is useful (RCPsych, 2011).

Another barrier is that diagnostic criteria may also not be directly applicable to older adults with alcohol use disorders. International Statistical Classification of Diseases and Related Health Problems, 10th Revision (ICD 10) and Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM 5) are often considered the gold standard for research, but several of the items used in the diagnostic criteria (such as impairment of social, occupational, or recreational activity) may not be relevant to older adults (Beullens and Aertgeerts, Reference Beullens and Aertgeerts2004). Further, alcohol intake may not be as dramatically elevated as in younger adults, and symptoms and signs of dependence and withdrawal may be less clear, or confused with mental illness or normal aging (Graham, Reference Graham1986). Importantly, intake at relatively modest levels may cause problems owing to physiological changes in older adults while not developing physiological dependence. Frequency, quantity, and pattern of consumption may be more appropriate considerations in the assessment of alcohol disorders in older adults and are not included in either DSM-IV or ICD-10 (RCPsych, 2011).

Official guidance in the United Kingdom makes minimal reference to older adults and alcohol use disorders. This institutional neglect of the issue also acts as a barrier. The National Institute for Health and Care Excellence (NICE; 2011) guidance report, Alcohol Use Disorders: Diagnosis, Assessment and Management of Harmful Drinking and Alcohol Dependence, makes only brief reference to the needs of older adults in respect of the need to reduce the threshold for alcohol misuse when using screening instruments and assessing the severity of alcohol dependence and the need to consider in-patient care more readily for detoxification. It not only acknowledges the higher risk of alcohol-related harm in older adults but also stresses that there is no reason why drug treatments should be considered clinically ineffective in this age group.

A similar situation can be seen in countries other than the United Kingdom, for example, including Australia (Australian Government Department of Health, 2013) and Canada (Giesbrecht et al., Reference Giesbrecht2013), confirming that this is an international problem. Very few countries have specific guidance on alcohol consumption for older adults. A Swedish National Institute of Public Health report (Hallgren et al., Reference Hallgren, Hogberg and Andreasson2010) pointed out that most European Union member states do not currently have alcohol consumption guidelines developed specifically for older adults with Italy being the only exception.

The National Institute on Alcohol Abuse and Alcoholism (NIAAA, 2008) in the United States recommends a limit of one standard drink a day for older men and women. Department of Health guidance in the United Kingdom reports a recommended level of three to four units of alcohol a day for men and two to three units of alcohol a day for women, but does not mention the vulnerability of older adults nor offers any additional guidance for this age group (Department of Health, 2013). However, on a positive note, the recent Government Alcohol Strategy (HM Government, 2012) makes reference to the need to examine further whether separate guidance on recommended limits in adults aged 65 years and over is needed. The RCPsych report (2011) suggested that recent evidence shows the upper safe limit for older adults to be 11 units a week with no more than three units in one session.

In a recent UK study conducted by Knott et al. (Reference Knott, Scholes and Shelton2013), age-specific drinking recommendations from the RCPsych were applied to available data from 2008. They found that when using this practice, the number of older drinkers classified as hazardous consumers rose to a level greater than that found among young adults aged 16–24, representing 1.2 million people aged over 65 years and a 3.6-fold increase over the existing definitions. Similarly, those drinking in excess of these proposed daily-recommended limits increased 2.5-fold to over 3 million in 2008. This study demonstrates the importance of age-specific guidelines, and the need for more research and public health campaigns in this area.

Tools for detection

When selecting tools for detecting alcohol use disorders, it is important to consider ease of use, patient acceptability, sensitivity, and specificity in this age group, in particular (O’Connell et al., Reference O’Connell2004). There are many different methods available for attempting to identify alcohol use disorders in older adults, including simple clinical enquiry, laboratory tests, and structured assessments. However, most alcohol screening instruments are not designed specifically for the older population and each method of detection has its own limitations. Table 2 outlines the main available methods and describes the advantages and disadvantages of each.

Table 2. Assessment tools available for detecting alcohol misuse disorders in older adults

One of the main issues with using such screening tools is that the definition of hazardous consumption used for younger adults does not accurately apply to the older population, who may experience significant harm with much lower levels of alcohol use. Traditional screening tests largely focus on high levels of alcohol beverage use and dependence, therefore potentially not identifying the consequences of lower levels of alcohol consumption on the physical and psychosocial health of older individuals (Fink et al., Reference Fink, Hays, Moore and Beck1996). Alcohol in this population is also far more likely to be used in combination with medications, medical illness, or pre-existing diminished physical, emotional, or social function. Older adults have higher sensitivity and higher blood levels with lower alcohol consumption (Smith, Reference Smith1995), and therefore the amount of alcohol consumed is not a reliable measure of alcohol problems. As various symptoms and syndromes, including falls and accidents, cognitive impairment, insomnia, self-neglect, and depression, may be useful indicators of alcohol use disorders (Reid and Anderson, Reference Reid and Anderson1997), it may be better to examine such behavioral and health indicators rather than focusing too much upon the actual amounts of alcohol consumed.

The role of stigma should not be underestimated, and therefore the reliability of self-report is a significant issue (Dar, Reference Dar2006). Older adults have a particularly marked tendency to under-report their drinking, often missing out alcoholic drinks, which they regard as medicinal to alleviate other health problems (Naik and Jones, Reference Naik and Jones1994). Furthermore, if they are isolated, there may be no collateral history or family may not be aware of the extent of their alcohol use, making detection even more difficult.

Alcohol screening in this group of people may be further complicated by the presence of cognitive impairment and such patients may be unsuitable for alcohol services due to poor insight and motivation and being unable to engage in interventions or retain information. Services have particular difficulty in meeting the needs of older adults with dementia and cognitive impairment associated with alcohol misuse (Cox et al., Reference Cox, Anderson and McCabe2004). The symptoms of alcoholism may also be confused with other physical or mental health problems. It can present in a large number of non-specific ways, including accidents, depression, insomnia, confused states, and self-neglect, many of which are also linked with the aging process and therefore may mimic other geriatric illnesses (Alcohol Concern, 2002).

Screening for alcohol misuse in older adults can be conducted in a number of clinical settings, including primary care, specialist services, and accident and emergency. Each environment poses its own particular challenges and barriers. Within primary care, physicians will increasingly come across alcohol-related problems in the growing population of older adults (Conigliaro et al., Reference Conigliaro, Kraemer and McNeil2000). Time pressures also present an issue with considerable time and resources needed to carry out all preventative and screening services in this population. Other common barriers include inadequate reimbursement for work undertaken, patient refusal, and a lack of physician expertise (Yarnall et al., Reference Yarnall, Polla, Ostbye, Krause and Michener2003).

The emergency department offers a useful place for detection with a high proportion of attendees presenting with alcohol-related problems. There is a continued upward trend in alcohol-related admissions to hospitals in England among older adults aged over 65 years in the last decade. In 2010, there were over half a million alcohol-related admissions of over 65-year olds, more than double the number in 2002. In males aged over 65 years, there has been a 175% increase between 2002 and 2010 and in women a 145% increase over the same period (Institute of Alcohol Studies, 2014). There is an ideal opportunity to identify alcohol use disorders in emergency department attendees, who often present at times of crisis and can be frequent utilizers of services. The REDUCE project based at St Mary's Hospital in London now regularly screens older patients when they present at A and E (Age Concern, 2002). However, screening within emergency departments can present problems (D’Onofrio and Degutis 2004/Reference D’Onofrio and Degutis2005), which include the busy environment and limited time. Staff may feel it is not their role or lack confidence to address this issue. They may also feel that interventions are ineffective and resources may not be available to carry out screening. Emergency departments may also focus solely on the presenting problem, thus missing an opportunity for intervention.

There is also an opportunity for screening in other settings. Henni et al. (Reference Henni, Bideau, Routon, Berrut and Cholet2013) investigated underdiagnosis of alcohol problems in older adults within acute inpatient geriatric units. They showed high levels of alcohol use disorders (at risk, harmful use, or dependence), but crucially only very few had been asked about their alcohol consumption. They concluded that screening should be conducted for every inpatient.

Next steps and future research

Notwithstanding assumptions of poor outcome in this population, in fact, research evidence suggests that appropriate treatment can be highly beneficial. Existing instruments for screening and diagnosis specifically for older adults are available but have their limitations and are not widely used. We advocate a more active approach to case finding and more realistic approaches to treatment based upon good research. In order to improve this situation, we suggest that there needs to be a change in societal attitudes, leading to reduced stigma around drinking in late life: a public health response, age-appropriate models of treatment, and higher priority for research in this age group. Alcohol abuse is an international problem affecting many countries, so there is potential for collaboration in finding effective approaches and interventions.

In summary, there is a need for coherent and targeted public health campaigns, on-going efforts to overcome stigma, better research, better tools for detection of the problem, and better available treatments and services.
