Trends in substance abuse treatment 1998-2008: increasing older adult first-time admissions for illicit drugs

Cognition and adaptive functioning in older people attending drug and alcohol services

BACKGROUND

Substance use disorders in older adults are expected to increase dramatically in the coming years. Given the increased susceptibility to cognitive deficits in older substance users (defined here as aged 50+ years due to the accelerated health decline observed in this population), it is important to consider the functional correlates of cognitive impairment in these older adults. This study details the cognitive status of older individuals attending outpatient drug and alcohol (D&A) treatment services and seeks to determine of the association of cognitive impairment to self-reported daily functioning.

METHODS

Ninety nine clients aged 50 years or over attending outpatient D&A treatment services in Sydney, Australia participated. Cognition was assessed using the Addenbrooke's Cognitive Examination - Revised (ACE-R). Recent substance use (Australian Treatment Outcome Profile), physical and mental health (SF12, Geriatric Depression Scale), social isolation (Lubben Social Network Scale), and activities of daily living (Bayer ADL Scale) were also assessed.

RESULTS

Nearly two-thirds of participants screened positive for cognitive impairment on the ACE-R; 41% and 65% of clients met the cut-off scores for mild cognitive impairment (MCI) and more severe cognitive impairment, respectively. Self-reported seizure history was a predictor of cognitive impairment.

CONCLUSIONS

The results suggest that cognitive impairment in this group is common. The assessment of cognitive status for this older group of patients should not only include the identification of cognitive impairment but also encompass mental health and social functioning. A greater understanding of the needs of this cohort will also enable better co-ordination with other health and welfare services tailored to this population.

Demographic trends of binge alcohol use and alcohol use disorders among older adults in the United States, 2005-2014

BACKGROUND

Alcohol use is common among older adults, and this population has unique risks with alcohol consumption in even lower amounts than younger persons. No recent studies have estimated trends in alcohol use including binge alcohol use and alcohol use disorders (AUD) among older adults.

METHODS

We examined alcohol use among adults age ≥50 in the National Survey on Drug Use and Health (NSDUH) from 2005 to 2014. Trends of self-reported past-month binge alcohol use and AUD were estimated. Logistic regression models were used to examine correlates of binge alcohol use and AUD.

RESULTS

The prevalence of both past-month binge alcohol use and AUD increased significantly among adults age ≥50 from 2005/2006 to 2013/2014, with a relative increase of 19.2% for binge drinking (linear trend p<0.001) and a 23.3% relative increase for AUD (linear trend p=0.035). While males had a higher prevalence of binge alcohol use and AUD compared to females, there were significant increases in both among females. In adjusted models of aggregated data, being Hispanic, male, and a smoker or illicit drug user were associated with binge alcohol use, while being male, a smoker, an illicit drug user, or reporting past-year depression or mental health treatment were associated with AUD.

CONCLUSIONS

Alcohol use among older adults is increasing in the US, including past-month binge alcohol use and AUD with increasing trends among females. Providers and policymakers need to be aware of these changes to address the increase of older adults with unhealthy drinking.

Quality Pain Care for Older Adults in an Era of Suspicion and Scrutiny

In two decades, the pendulum has swung from focusing on the undertreatment of pain by prescribers who fail to use medically necessary opioid agents to an intense focus on overprescribing opioid medications and the harms they cause. Within these two extremes rests the older adult with pain and in need of safe and effective care. Today, health care providers are practicing in an era of scrutiny, with new guidelines and regulations superseding their compassion and clinical judgment about the best treatment options when older adults have pain across the care continuum. Media depicting opioid medications as lethal, unnecessary, and highly addictive that do not distinguish non-medical from therapeutic use or legitimately versus illegally obtained drugs are widely reported. These reports and legislative focus on treating addiction have silenced and further stigmatized older adults with persistent pain. Patients and professionals treating pain need to provide balance of multimodal pain management strategies to safely manage persistent pain based on a comprehensive assessment and personalized approach.

Association between age, substance use, and outcomes in Medicare enrollees with prostate cancer

OBJECTIVE

To analyze the association between age, substance use, and outcomes in fee-for-service Medicare enrollees with advanced prostate cancer.

METHODS

Retrospective longitudinal cohort study of elderly men diagnosed with advanced prostate cancer using SEER-Medicare data between 2000 and 2009. Substance use disorder was identified using claims for alcoholic psychosis, drug psychoses, alcohol dependence syndrome, drug dependence, and non-dependent use of drugs. We compared health service use, cost, and 5-year mortality across two age-groups: young-old (66-74years) and old-old (≥ 75years).

RESULTS

Cohort consisted of 8484 young-old and 5763 old-old patients with advanced prostate cancer. Prevalence of substance use was 12.4% in young-old and 7.4% in old-old group. For the young-old group, the 'drug psychoses and related' category had the highest inpatient, outpatient, and ER usage as well as the highest hazard of mortality (HR=2.2; CI=1.5, 3.1), compared to those without substance use. Compared to the no substance use group, those with substance use in the follow-up phase had higher inpatient and ER visits, and those with substance use in treatment phase had higher outpatient visits and highest hazard of mortality (HR=1.6; CI=1.4, 1.9). For the old-old group, the 'drug psychoses and related' category was associated with highest inpatient and outpatient use; and 'Non-dependent use of drugs' were associated with highest ER use, compared to those without substance use.

CONCLUSION

Intersection of cancer and substance use disorder in elderly patients with advanced prostate cancer covered by Medicare is age specific. An integrated and multidisciplinary approach to screen, refer, and treat substance use in patients with prostate cancer may improve outcomes and reduce costs.

Prevalence and Detection of Prescription Opioid Misuse and Prescription Opioid Use Disorder Among Emergency Department Patients 50 Years of Age and Older: Performance of the Prescription Drug Use Questionnaire, Patient Version

BACKGROUND

Despite increased concern about prescription opioid misuse among older adults, there is limited work examining the best means to identify misuse by older adults. The goal of this investigation was to examine the performance the Prescription Drug Use Questionnaire Patient Version (PDUQp), in detecting prescription opioid misuse and prescription opioid use disorders among adult emergency department (ED) patients aged 50 years and older.

METHODS

This was a cross-sectional study of a random sample of adult ED patients, aged 50 years and older. All participants were without cognitive impairment and reported prescription opioid use within the past 30 days. We evaluated the sensitivity, specificity, predictive values, and receiver operating characteristics of the PDUQp against a standard definition of opioid misuse and DSM-5 criteria for prescription opioid use disorder.

RESULTS

Overall, 112 participants completed the study; 74 were aged 50-64 years and 38 were aged 65 years and older. Over half of the participants satisfied DSM-5 criteria for prescription opioid use disorder, with slightly less participants reporting misuse. Overall, the respective sensitivity and specificity of the PDUQp was: 44% and 79% (Receiver Operating Characteristic [ROC] area under the curve: 0.61) for prescription opioid misuse, 38% and 81% (ROC area under the curve: 0.64) for the presence of any prescription opioid use disorder, and 56% and 75% (ROC area under the curve: 0.71) for moderate to severe prescription opioid use disorder.

CONCLUSIONS

Based on this preliminary work, the PDUQp may be a viable instrument to screen for prescription opioid misuse and prescription opioid use disorder, but it likely requires modifications to optimize its predictive ability in adults over age 50 years.

Maturing out, natural recovery, and dual diagnosis: What are the implications for older adult mental health services?

In 1962, Charles Winick proposed that addiction was a self-limiting process, whereby individuals stopped using substances once the stresses of life transitions ceased. The notion of maturing out, as labelled by Winick, often forms the basis of the natural recovery movement in alcohol and other drug (AOD) research, aiding the notion that older individuals either cease their substance use or fall victim to the higher mortality rates prevalent in substance-using populations. As more consumers present to adult mental health treatment settings with co-occurring substance use disorders, the idea that individuals will simply cease using AOD is outdated. Given the future challenges of an ageing population, it is prudent to explore those who fail to mature out of substance use, as well as challenge the notion that older adult mental health services rarely encounter substance-using individuals. The present study explores Winick's research in the context of an ageing population and older adult mental health services. It also ponders the proposition put forth in subsequent research that older individuals with lifelong substance use switch to substances that are easier to obtain and better tolerated by their ageing bodies.

Referrals and Treatment Completion for Prescription Opioid Admissions: Five Years of National Data

This study examines sources of referral for prescription opioid admission to substance use disorder treatment facilities and their relative completion success rates using secondary analysis of an existing data set (treatment episode datasets-discharge). Five years of data from public and private treatment facilities were extracted for client discharges with no prior treatment (N=2,909,884). Healthcare professionals account for very few referrals to treatment (<10%). Prescription opioid clients referred into treatment had lower treatment success compared to other substance clients and when referred by healthcare providers had lower success rates (OR=0.72, 95% CI 0.70-0.75) than clients from other referral sources. Fewer treatment referrals for prescription opioid misuse by healthcare providers and lower success rates are significant and timely findings due to the prevalence of prescription opioid misuse. Healthcare providers are well positioned to refer early for prescription opioid misuse and continue support of their patients during treatment.

Geriatric alcohol use disorder: a review for primary care physicians

Alcohol use disorder in the geriatric population is a growing public health problem that is likely to continue to increase as the baby boomer generation ages. Primary care providers play a critical role in the recognition and management of these disorders. This concise review will focus on the prevalence, risk factors, screening, and clinical management of geriatric alcohol use disorder from a primary care perspective.

Cocaine Abuse in Later Life: A Case Series and Review of the Literature

OBJECTIVE

To raise awareness about the growing trend of cocaine abuse in later years as an underdiagnosed, undertreated, and comorbid condition in older individuals. Three cases of cocaine use in patients over the age of 50 years in the Malcolm Randall Veterans Medical Center, Gainesville, Florida, within a 10-day span in 2013 are presented.

DATA SOURCES

PubMed was searched using combinations of keywords, including cocaine, addiction, elderly, and aging, to find articles published between 1986 and 2013.

STUDY SELECTION

In total, 37 articles were selected for inclusion on the basis of their relevance to the objective and importance to the representation of cocaine abuse, including international guidelines for addiction.

DATA EXTRACTION

Each article was reviewed for eligibility. Final decisions were made following full-text review.

RESULTS

Cocaine addiction remains a high-morbidity chronic-relapsing illness with few treatment options. A review of the literature shows that late-life cocaine use is sparsely recognized. Of particular interest are the clinical presentations in which a higher index for detection is warranted. The high rate of medical comorbidity associated with cocaine use, especially cerebrovascular deficits, presents special treatment and social challenges.

CONCLUSIONS

As the number of older individuals admitted for substance use continues to climb, clinicians must adapt to the changing demographics by increasing screening, early detection, and treatment options for older persons.

Dual diagnosis in older adults: a review

Dual diagnosis is associated with frequent relapse, poor treatment engagement and overall unsatisfactory treatment outcomes. A comprehensive review of the contemporary literature examining this issue was conducted, finding a paucity of literature concerning dual diagnosis in older adults. Of the literature appraised for this review, a number of studies examined US Veteran's Affairs populations, which were largely male. Studies concerning older mental health populations were scarce. During the literature search, a number of background studies that influenced contemporary research regarding dual diagnosis in older adults were found; these studies were examined regarding their contribution to contemporary paradigms concerning older adults with co-occurring mental illness and substance use disorders. This review presents the results of the contemporary literature concerning dual diagnosis in older adults. Several recurring themes emerge from the literature, including the notion of a statistically small population that, in absolute terms, represents a sizeable number of individuals coming to the attention of aged mental health services in the future. Additionally, the potential for under-diagnosis in this cohort is highlighted, potentially creating a hidden population of older adults with dual diagnosis.

Mortality among older adults with opioid use disorders in the Veteran's Health Administration, 2000-2011

BACKGROUND

The population of people with opioid use disorders (OUD) is aging. There has been little research on the effects of aging on mortality rates and causes of death in this group. We aimed to compare mortality in older (≥ 50 years of age) adults with OUD to that in younger (<50 years) adults with OUD and older adults with no history of OUD. We also examined risk factors for specific causes of death in older adults with OUD.

METHODS

Using data from the Veteran's Health Administration National Patient Care Database (2000-2011), we compared all-cause and cause-specific mortality rates in older adults with OUD to those in younger adults with OUD and older adults without OUD. We then generated a Cox regression model with specific causes of death treated as competing risks.

RESULTS

Older adults with OUD were more likely to die from any cause than younger adults with OUD. The drug-related mortality rate did not decline with age. HIV-related and liver-related deaths were higher among older OUD compared to same-age peers without OUD. There were very few clinically important predictors of specific causes of death.

CONCLUSION

Considerable drug-related mortality in people with OUD suggests a need for greater access to overdose prevention and opioid substitution therapy across the lifespan. Elevated risk of liver-related death in older adults may be addressed through antiviral therapy for hepatitis C virus infection. There is an urgent need to explore models of care that address the complex health needs of older adults with OUD.

Demographic Trends of Adults in New York City Opioid Treatment Programs--An Aging Population

BACKGROUND

The population of adults accessing opioid treatment is growing older, but exact estimates vary widely, and little is known about the characteristics of the aging treatment population. Further, there has been little research regarding the epidemiology, healt h status, and functional impairments in this population.

OBJECTIVES

To determine the utilization of opioid treatment services by older adults in New York City.

METHODS

This study used administrative data from New York State licensed drug treatment programs to examine overall age trends and characteristics of older adults in opioid treatment programs in New York City from 1996 to 2012.

RESULTS

We found significant increases in utilization of opioid treatment programs by older adults in New York City. By 2012, those aged 50-59 made up the largest age group in opioid treatment programs. Among older adults there were notable shifts in demographic background including gender and ethnicity, and an increase in self-reported impairments.

CONCLUSIONS/IMPORTANCE

More research is needed to fully understand the specific characteristics and needs of older adults with opioid dependence.

Treatment use, perceived need, and barriers to seeking treatment for substance abuse and mental health problems among older adults compared to younger adults

BACKGROUND

This study examined age group differences in and correlates of treatment use and perceived treatment need for substance use disorders (SUD) and mental health (MH) problems as well as self-reported barriers to treatment among people 65+ years old vs. 26-34, 35-49, and 50-64 years old.

METHODS

Data are from the 2008 to 2012 National Survey on Drug Use and Health (NSDUH) (N = 96,966). Age group differences were examined using descriptive bivariate analyses and binary logistic regression analyses.

RESULTS

The 65+ age group was least likely to use treatment and perceive treatment need, but the 50-64 age group was more similar to the younger age groups than the 65+ age group. Controlling for age, other predisposing, and enabling factors, alcohol and illicit drug dependence and comorbid SUD and MH problems increased the odds of SUD treatment use. Of MH problems, anxiety disorder had the largest odds for MH treatment use. Bivariate analyses showed that lack of readiness to stop using and cost/limited insurance were the most frequent barriers to SUD and MH treatment, respectively, among older adults, and they were less likely than younger age groups to report stigma/confidentiality concerns for MH treatment.

CONCLUSIONS

Older adults will become a larger portion of the total U.S. population with SUD and/or MH problems. Healthcare providers should be alert to the need to help older adults with SUD and/or MH problems obtain treatment.

Older homeless people: increasing numbers and changing needs

Evidence from England, Australia, Canada, Japan and the USA indicates that the single homeless population is ageing, and that increasing numbers of older people are homeless. This paper reviews evidence of changes in the age structure of the single homeless population, and the factors that are likely to have had an influence on the growth of the older homeless population. In many Western cities, the housing situation of older people is changing and there is a growing reliance on the private rented sector. Unemployment is also having an impact on older people who are under the official retirement age. An increasing number of older people are experiencing problems linked to alcohol, drugs, gambling and criminality, and these are all behaviours that can contribute to homelessness. Despite high levels of morbidity and disability among older homeless people, they are a relatively neglected group and receive little attention from policy makers and mainstream aged care services.

Psychosocial and reincarceration risks among older adults in mental health courts

OBJECTIVE

Older adults are increasingly involved in the criminal justice system, yet there is limited research regarding their needs and experiences. This study examined differences in psychosocial experiences and reincarceration between older and younger adults with psychiatric disorders involved in the criminal justice system.

METHODS

Participants (N = 80) were recruited from two mental health courts in the midwestern United States. Bivariate analyses examined age-related differences in psychosocial experiences and reincarceration between younger and older participants.

RESULTS

Older adults, on average, experienced more treatment adherence and fewer probation violations than younger adults during the 6-month follow-up; however, they experienced comparable risk for reincarceration. Older adults' substance use, service use, housing instability, and program retention were similar to their younger counterparts.

CONCLUSION

Despite older mental health court participants' treatment adherence and reduced probation violations, they are at risk for incarceration, substance use, and housing instability.

Substance use disorder and its effects on outcomes in men with advanced-stage prostate cancer

BACKGROUND

Substance use disorder in patients with cancer has implications for outcomes. The objective of this study was to analyze the effects of the type and timing of substance use on outcomes in elderly Medicare recipients with advanced prostate cancer.

METHODS

This was an observational cohort study using Surveillance, Epidemiology, and End Results (SEER)-Medicare linked data from 2000 to 2009. Among men who were diagnosed with advanced prostate cancer between 2001 and 2004, we identified those who had a claim for substance use disorder in the year before cancer diagnosis, 1 year after cancer diagnosis, and an additional 4 years after diagnosis. The outcomes investigated were use of health services, costs, and mortality.

RESULTS

The prevalence of substance use disorder was 10.6%. The category drug psychoses and related had greater odds of inpatient hospitalizations (odds ratio [OR], 2.3; 95% confidence interval [CI], 1.9-2.8), outpatient hospital visits (OR, 2.6; 95% CI, 1.9-3.6), and emergency room visits (OR, 1.7; 95% CI, 1.2-2.4). Substance use disorder in the follow-up phase was associated with greater odds of inpatient hospitalizations (OR, 2.0; 95% CI, 1.8-2.2), outpatient hospital visits (OR, 2.0; 95% CI, 1.7-2.4), and emergency room visits (OR, 1.7; 95% CI, 1.5-2.1). Compared with men who did not have substance use disorder, those in the category drug psychoses and related had 70% higher costs, and those who had substance use disorder during the follow-up phase had 60% higher costs. The hazard of all-cause mortality was highest for patients in the drug psychoses and related category (hazard ratio, 1.3; 95% CI, 1.1-1.7) and the substance use disorder in treatment phase category (hazard ratio, 1.5; 95% CI, 1.3-1.7).

CONCLUSIONS

The intersection of advanced prostate cancer and substance use disorder may adversely affect outcomes. Incorporating substance use screening and treatments into prostate cancer care guidelines and coordination of care is desirable.

Substance abuse among older adults

Although the myth that older adults do not use mood-altering substances persists, evidence suggests that substance use among older adults has been underidentified for decades. The baby boom generation is unique in its exposure to, attitudes toward, and prevalence of substance use-causing projected rates of substance use to increase over the next twenty years. Given their unique biological vulnerabilities and life stage, older adults who misuse substances require special attention. Prevalence rates of substance use and misuse among older adults, methods of screening and assessment unique to older adults, and treatment options for older adults are reviewed.

Younger versus older African Americans: patterns and prevalence of recent illicit drug use

OBJECTIVES

The current study examined recent substance use among younger and older African Americans and factors associated with recent use.

METHODS

The current study used a subset of African American men and women (N = 260) from the NEURO-HIV Epidemiological Study (Mage = 42, SD = 9.27; 59% female). Self-report of past 6 month substance use was evaluated for 21 different substances by routes of administration (ROA).

RESULTS

Older adults were 1.9 times (AOR = 1.92, 95% CI = 1.13-3.26) more likely to have used crack in the past 6 months and half as likely to have used marijuana (AOR = .44, 95% CI = .25-.77). There were no significant differences for heroin use.

DISCUSSION

Substance use at midlife may have significant implications for adverse social and health outcomes among African Americans. Findings support the need to better understand the developmental pathways of drug use and dependence among African Americans.

Substance use disorders and psychiatric comorbidity in mid and later life: a review

BACKGROUND

Globally, adults aged 65 years or older will increase from 516 million in 2009 to an estimated 1.53 billion in 2050. Due to substance use at earlier ages that may continue into later life, and ageing-related changes in medical conditions, older substance users are at risk for substance-related consequences.

METHODS

MEDLINE and PsychInfo databases were searched using keywords: alcohol use disorder, drug use disorder, drug misuse, substance use disorder, prescription drug abuse, and substance abuse. Using the related-articles link, additional articles were screened for inclusion. This review focused on original studies published between 2005 and 2013 to reflect recent trends in substance use disorders. Studies on psychiatric comorbidity were also reviewed to inform treatment needs for older adults with a substance use disorder.

RESULTS

Among community non-institutionalized adults aged 50+ years, about 60% used alcohol, 3% used illicit drugs and 1-2% used nonmedical prescription drugs in the past year. Among adults aged 50+, about 5% of men and 1.4% of women had a past-year alcohol use disorder. Among alcohol users, about one in 14 users aged 50-64 had a past-year alcohol use disorder vs one in 30 elder users aged 65+. Among drug users aged 50+, approximately 10-12% had a drug use disorder. Similar to depressive and anxiety disorders, substance use disorders were among the common psychiatric disorders among older adults. Older drug users in methadone maintenance treatment exhibited multiple psychiatric or medical conditions. There have been increases in treatment admissions for illicit and prescription drug problems in the United States.

CONCLUSIONS

Substance use in late life requires surveillance and research, including tracking substance use in the racial/ethnic populations and developing effective care models to address comorbid medical and mental health problems.

Relationship of age to impulsivity and decision making: a baseline secondary analysis of a behavioral treatment study in stimulant use disorders

Because stimulant use disorders remain prevalent across the lifespan, cognition is an important area of clinical care and research focus among aging adults with stimulant use disorders. This secondary analysis of a National Institute on Drug Abuse Clinical Trials Network study suggests that decision making, verbal learning/memory, executive function, and set shifting are important cognitive domains to screen clinically and treat in aging adults with stimulant use disorders. Some suggestions are made on how clinical treatment providers can practically use these results. An important direction for future research is the development of cognitively remediating treatments for impaired cognitive domains in aging adults with stimulant use disorders.

Help seeking for drug and alcohol problems among adults age 50 and older: a comparison of the NLAES and NESARC surveys

BACKGROUND

Due to population aging and generational changes in alcohol and drug use, substance use disorders and treatment need are projected to increase among adults over 50. We analyzed data from two national surveys conducted 10 years apart [(NLAES (1991-1992) and NESARC (2001-2002)] to explore changes in help-seeking for alcohol and drug problems among adults over age 50.

METHODS

Data were pooled on help seeking for substance related problems, sociodemographic and clinical variables, and services type (i.e., formal and informal). Differences between the surveys were assessed, and help seeking among those under age 50 was compared to younger individuals; changes in the sociodemographic and clinical correlates of help seeking among those over age 50 were examined.

RESULTS

Among those 50 and older, rates of lifetime help seeking for any substance problem were higher in NESARC than NLAES, and percentages of those considering but not getting help were also higher in NESARC. Among those 50+, rates of past-year help seeking for drug use were higher in NESARC, but among those with lifetime substance use disorders, help seeking rates for alcohol and any substance were lower in the NESARC. Older help seekers in the NESARC were less likely to be White, more likely to be low income, and more likely to be current or former drug users than NLAES help seekers.

CONCLUSIONS

This study documents increased rates of help seeking for substance related problems among those 50 and older and identifies cohort differences in profile of past-year help seekers.

Major depressive disorder in vulnerable groups of older adults, their course and treatment, and psychiatric comorbidity

BACKGROUND

Although a number of epidemiology studies of major depressive disorder (MDD) in older adults have been reported, most of them suffer four limitations: (1) the sample was not nationally representative; (2) the sample was relatively small or only one or two sociodemographic correlates of MDD were examined; (3) psychiatric comorbidity was not examined; and (4) the clinical characteristics of MDD were not reported. This study (1) examines the prevalence of DSM-IV MDD across different demographics, especially the vulnerable ones; (2) identifies clinical characteristics of DSM-IV MDD, such as onset, course, and treatment; and (3) evaluates the comorbidity of DSM-IV MDD with anxiety disorder, substance-use disorder, and personality disorder.

METHODS

We analyzed data on 8,205 individuals aged 65 or older from the National Epidemiologic Survey on Alcohol and Related Conditions (2001-2002), a nationally representative survey of the noninstitutionalized U.S. household population. The Alcohol Use Disorder and Associated Disabilities Interview Schedule-DSM-IV version assessed MDD, anxiety, substance use, personality disorders, and pathological gambling. The survey also included demographic characteristics: age, sex, race/ethnicity, marital status, education, employment status, personal income, urban vs. rural residence, and region of the country.

RESULTS

Marital status and gender were associated with MDD, whereas race and socioeconomic characteristics were not. Specifically, the prevalence rates of past-year MDD were significant greater for females (3.6%) than males (2.0%) and higher for widowed (4.9%) or separated/divorced (3.5%) than married (1.85%). The mean onset age was 50 years and the average number of lifetime episodes was 4.4. Only half of older adults with MDD had received treatment, even though one-fourth had thought about suicide. Anxiety disorder, substance dependence, and pathological gambling were highly associated with MDD.

CONCLUSION

Prevention could be targeted to older women and those who were widowed, separated, or divorced and low treatment rate was also alarming. More research is needed for the comorbid psychiatric disorders in late-life depression because of their impact on the course and prognosis of MDD.

Demographic and clinical characteristics of middle-aged versus younger adults enrolled in a clinical trial of a web-delivered psychosocial treatment for substance use disorders

OBJECTIVE

Evidence suggests that substance abuse is becoming more prevalent in middle-aged adults. The objective of this secondary analysis was to add to the growing empirical literature on the unique features of middle-aged substance abuse populations.

METHODS

We descriptively compared baseline demographic and clinical characteristics of middle-aged (age 45-62 years, n = 111) and younger (age 18-44 years, n = 395) substance abusers entering a Web-based psychosocial treatment study as part of the National Institute on Drug Abuse Clinical Trials Network.

RESULTS

A significantly greater percentage of middle-aged adults were nonwhite and had a marital status other than single/never married. There was a significant association between frequency of Internet use and the age group. Forty-six percent of middle-aged adults versus 21% of younger adults reported no Internet use in the prior 90 days. A significantly greater percentage of middle-aged adults used cocaine, and a significantly greater percentage of younger adults used marijuana and opioids. Clinically significant cognitive impairment (z < -1.0) was found for the average participant in both groups on logical association of familiar concepts.

CONCLUSIONS

This secondary analysis of a National Institute on Drug Abuse Clinical Trials Network study provides additional information on the unique features of middle-aged substance abusers. Increasing knowledge of similarities and differences between younger and middle-aged substance abusers can help with potential age-specific substance abuse treatment planning.

A review of existing treatments for substance abuse among the elderly and recommendations for future directions

Background

With population aging, there is widespread recognition that the healthcare system must be prepared to serve the unique needs of substance using older adults (OA) in the decades ahead. As such, there is an increasingly urgent need to identify efficient and effective substance abuse treatments (SAT) for OA. Despite this need, there remains a surprising dearth of research on treatment for OA.

Aims of review

This review describes and evaluates studies on SAT applied to and specifically designed for OA over the last 30 years with an emphasis on methodologies used and the knowledge gained.

Methods

Using three research databases, 25 studies published in the last 30 years which investigated the impact of SAT on OA and met specific selection criteria were reviewed.

Results

A majority of the studies were methodologically limited in that they were pre-to-post or post-test only studies. Of the randomized controlled trials, many were limited by sample sizes of 15 individuals or less per group, making main effects difficult to detect. Thus, with caution, the literature suggests that among treatment seeking OA, treatment, whether age-specific or mixed-age, generally works yielding rates of abstinence comparable to general populations and younger cohorts. It also appears that with greater treatment exposure (higher dosage), regardless of level of care, OA do better. Finally, based on only two studies, age-specific treatment appears to potentiate treatment effects for OA. Like younger adults, OA appear to have a heterogeneous response to treatments, and preliminary evidence suggests a possibility of treatment matching for OA.

Conclusions

Expansion of research on SAT for OA is urgently needed for maximum effectiveness and efficiency of the healthcare system serving these individuals. Future research needs to include laboratory and community based randomized controlled trials with high internal validity of previously vetted evidenced-based practices, including Motivational Interviewing, cognitive behavioral therapy, and medications such as naltrexone, to determine the best fit for OA.

Just say know: an examination of substance use disorders among older adults in gerontological and substance abuse journals

This article examines the extent to which studies of alcohol abuse, illicit drug use, and prescription drug abuse among older adults appear in the leading gerontological and substance abuse journals. The authors reviewed articles published in the 10 social science gerontological journals and the 10 social science substance abuse journals with the highest 5-year impact factors in PubMed from 2000 to 2010. Articles were selected that presented original research on alcohol, substance, or prescription abuse with older adults aged 50 and older; and were identified through aging and substance abuse-related Medical Subject Headings and word searches of titles and abstracts (N = 634). Full text of each article was reviewed by the authors, and consensus determined inclusion in the final sample. Of the 19,953 articles published respectively in the top 10 gerontological and substance abuse journals, 181 articles met the inclusion criteria of reporting findings related to substance use disorders among older adults. Specifically, 0.9% (102 of 11,700) of articles from the top 10 gerontology journals and 1.0% (79 of 8,253) of articles from the top 10 substance abuse journals met the criteria. Most published articles addressed alcohol misuse/abuse or polysubstance abuse with few articles addressing illicit drug use or the misuse of prescription medications. Less than 1% of articles published in the 10 gerontology journals and the 10 substance abuse journals with the highest 5-year impact scores addressed substance abuse in older adults. Practitioners treating health and/or mental health problems are at a disadvantage in accurately identifying and treating these conditions in older adult populations without a proper understanding of the role of comorbid substance use disorders.

The subjective effects of cocaine: relationship to years of cocaine use and current age

BACKGROUND

Little is known about whether the duration of cocaine use or an individual's age may influence the acute effects of cocaine, patterns of use, and specific treatment needs.

OBJECTIVES

This post hoc analysis determined whether the duration of cocaine use or current age influenced the acute subjective response to cocaine. Data from four smoked cocaine self-administration laboratory studies were combined and analyzed to determine whether the subjective effects of a 25-mg smoked cocaine dose varied as a function of years of cocaine use or current age.

METHODS

Thirty-six nontreatment-seeking healthy cocaine users (ages 32-49) were admitted to studies lasting from 12 to 105 days. Participants rated the subjective effects of each cocaine dose from 0 to 100 by completing a computerized self-report visual analogue scale (VAS). The main outcome measures were the change in VAS ratings between a baseline placebo dose and the first 25-mg dose of smoked cocaine.

RESULTS

No significant relationship was found between the subjective effects of cocaine and years of cocaine use (mean 20.9, range 5-30) or current age (mean 41.1, range 32-49).

CONCLUSION

Among long-term cocaine users between the ages of 32 and 49, the acute subjective effects of cocaine did not vary as a function of years of cocaine use or current age.

SCIENTIFIC SIGNIFICANCE

These data fail to support the incentive sensitization theory for addiction by Robinson and Berridge, as cocaine "liking" and "wanting" remained the same regardless of age or years of cocaine use.

The growing problem of illicit substance abuse in the elderly: a review

OBJECTIVE

To explore and integrate the extant data on the subject of illicit substance use and abuse in the elderly and to determine shortcomings in the current understanding of the problem and potential topics of future research.

DATA SOURCES

Ovid MEDLINE was searched (1960-2011) using the keywords substance use disorders and geriatrics; PsycINFO was searched (1967-2011) using the keywords drug abuse and geriatrics.

DATA EXTRACTION

The searches of Ovid MEDLINE and PsycINFO returned 35 and 85 results, respectively. Other relevant articles were identified by checking reference lists of the identified studies. A total of 26 articles with a focus on use of illicit substances, excluding alcohol, over-the-counter drugs, and prescription drugs, in the elderly were determined to be applicable to the review.

DATA SYNTHESIS

Limited data were available to combine between studies, but certain conclusions could be generalized among separate sources.

RESULTS

Geriatric substance abuse is a topic of growing interest, importance, and research; however, most of the existing literature has focused on licit substances. Illicit substance abuse has been incorrectly assumed to end as patients age, whereas in reality, elderly drug users are increasingly common and have a unique profile quite different from that of their younger counterparts.

CONCLUSIONS

Geriatric substance abuse is a common problem and includes both licit and illicit substances. There are not yet reliable screening instruments or treatment methods for identification and treatment of illicit substance abuse in the elderly. A high index of suspicion and consideration of illicit substance use as a real possibility are vital for early recognition and diagnosis of such abuse in the elderly.

Validation of the French version of the alcohol, smoking and substance involvement screening test (ASSIST) in the elderly

Background

Substance use disorders seem to be an under considered health problem amongst the elderly. The Alcohol, Smoking and Substance Involvement Screening Test (ASSIST), was developed by the World Health Organization to detect substance use disorders. The present study evaluates the psychometric properties of the French version of ASSIST in a sample of elderly people attending geriatric outpatient facilities (primary care or psychiatric facilities).

Methods

One hundred persons older than 65 years were recruited from clients attending a geriatric policlinic day care centre and from geriatric psychiatric facilities. Measures included ASSIST, Addiction Severity Index (ASI), Mini-International Neuropsychiatric Interview (MINI-Plus), Alcohol Use Disorders Identification Test (AUDIT), Revised Fagerstrom Tolerance Questionnaire-Smoking (RTQ) and MiniMental State(MMS).

Results

Concurrent validity was established with significant correlations between ASSIST scores, scores from ASI, AUDIT, RTQ, and significantly higher ASSIST scores for patients with a MINI-Plus diagnosis of abuse or dependence. The ASSIST questionnaire was found to have high internal consistency for the total substance involvement along with specific substance involvement as assessed by Cronbach’s α, ranging from 0.66, to 0.89 .

Conclusions

The findings demonstrate that ASSIST is a valid screening test for identifying substance use disorders in elderly.

Clinical implications of drug abuse epidemiology

Research on the epidemiology of illicit drug use disorders provides continued critical insights into the distribution and determinants of drug use and drug use disorders in the United States. This research serves as a foundation for understanding the etiology of these disorders, helping to disentangle the complex interrelationship of developmental, genetic, and environmental risk and protective factors. Building on an understanding of this research in substance abuse epidemiology, it is important for clinicians to understand the unique trends in drug use in the overall communities that they serve and the unique risk factors for given individuals. The generally high prevalence of substance use disorders, along with their high comorbidity with other psychiatric disorders and with the HIV epidemic, make prevention, evaluation, and referral for treatment for drug abuse an important part of routine clinical practice in a range of clinical settings, including primary care, psychiatric, and emergency department settings. Ongoing efforts to ensure insurance coverage parity for the treatment of mental health and substance use disorders offer the promise of continued improvements in the integration and availability of such services in the broader US health care system.

Age differences in heroin and prescription opioid abuse among enrolees into opioid treatment programs

Background

In the United States, among those entering opioid treatment programs (OTPs), prescription opioid (PO) abusers tend to be younger than heroin users. Admissions of older persons to OTPs have been increasing, and it is important to understand typical patterns of use among those older enrolees.

Methods

To disentangle the effect of age on recent heroin and PO abuse 29,114 enrolees into 85 OTPs were surveyed across 34 states from 2005-2009. OTPs where PO use was prevalent were oversampled.

Results

Mean age was 34; 28% used heroin only. Younger enrolees had increased odds of using POs relative to using heroin only but mixed model analysis showed that much of the total variability in type of use was attributed to variation in age between OTPs rather than within OTPs.

Conclusions

Organizational and cultural phenomena (e.g., OTP characteristics) must be examined to better understand the context of individual characteristics (e.g., age). If nesting of enrolees within OTPs is ignored, then associations that primarily operate at the OTP level may be misinterpreted as exclusively dependent on individuals.

There is no age limit for methadone: a retrospective cohort study

Background

Data from the US indicates that methadone-maintained populations are aging, with an increase of patients aged 50 or older. Data from European methadone populations is sparse. This retrospective cohort study sought to evaluate the age trends and related developments in the methadone population of Basel-City, Switzerland.

Methods

The study included methadone patients between April 1, 1995 and March 31, 2003. Anonymized data was taken from the methadone register of Basel-City. For analysis of age distributions, patient samples were split into four age categories from '20-29 years' to '50 years and over'. Cross-sectional comparisons were performed using patient samples of 1996 and 2003.

Results

Analysis showed a significant increase in older patients between 1996 and 2003 (p < 0.001). During that period, the percentage of patients aged 50 and over rose almost tenfold, while the proportion of patients aged under 30 dropped significantly from 52.8% to 12.3%. The average methadone dose (p < 0.001) and the 1-year retention rate (p < 0.001) also increased significantly.

Conclusions

Findings point to clear trends in aging of methadone patients in Basel-City which are comparable, although less pronounced, to developments among US methadone populations. Many unanswered questions on medical, psychosocial and health economic consequences remain as the needs of older patients have not yet been evaluated extensively. However, older methadone patients, just as any other patients, should be accorded treatment appropriate to their medical condition and needs. Particular attention should be paid to adequate solutions for persons in need of care.
