Substance abuse and the hospitalized elderly

Development of the Older Adult Prescription Drug Assessment Questionnaire for Case Workers

Instruments assessing geriatric case managers’ perceptions of prescription abuse are limited. Based on a review of current literature and pilot testing feedback, 22 items were initially assembled to form an older adult Prescription Drug Assessment Questionnaire (PDAQ). Case managers ( N = 161) at an older adult agency located in a Midwestern state were surveyed using the instrument. Data were subjected to exploratory factor analysis using principal axis factoring (PAF) and Promax rotation, and Horn’s parallel analysis determined the number of extracted factors. PAF generated a final 11-item three-factor model accounting for 51% of total variance explained: Standard Assessment (Factor 1; four items; ∞ = .83), Assessment Belief (Factor 2; three items; ∞ = .74), and Problem Scope (Factor 3; four items; ∞ = .62). The older adult PDAQ is a brief, data-driven instrument with acceptable psychometric properties for assessing perceptions of prescription drug abuse and misuse assessment and counseling.

Substance Addiction in Old Age

Abstract. There is a lack of studies using a structured face-to-face interview focusing on the full spectrum of substance addictions according to ICD or DSM classification systems in older patients. We therefore examined a cohort of 400 randomly selected, at least 65-year-old inpatients of a general hospital concerning addictive disorders using a well-tested structured clinical interview (DSM-IV-TR-based SKID-I). Nearly one third of this cohort was substance dependent: The 12-month prevalence rate for nicotine was 10.3% and for alcohol dependence 3%, with 24.4% and 66.7%, respectively, being severely dependent. These rates were similar to those found in the general German population of persons under 65 year of age. A fifth of the cohort was (mostly mildly) dependent on prescription drugs, remarkably including nonopioid analgesics. One case with a previous dependence on gabapentin was identified. Identification and management of addiction disorders should be considered as part of the basic geriatric assessment.

Prescription Drug Misuse in Late Adulthood

Prescription drug misuse is a public health problem, and older adults are at high risk. The underlying factors associated with this problem in late adulthood are not well understood. Using cross-sectional data from telephone interviews with individuals aged 60 years and older in Arizona and Florida ( N = 2,000), this study tests whether hypotheses derived from general strain and low self-control theories are supported while investigating misusing prescription medication. Results from the regression analyses reveal that the association between poor health (conceptualized as a strain) and misusing prescription drugs (conceptualized as criminal coping) is partially explained by depressive symptoms (conceptualized as negative emotionality). The link between problem drinking and prescription drug misuse is fully attenuated when low self-control is included in the model. The results confirm that both theories provide insight into this public health problem and that treatment strategies should target the underlying mechanisms that lead to misuse.

Alcohol screening in people with cognitive impairment: an exploratory study

OBJECTIVE

Alcohol misuse can coexist with and/or contribute to the development of cognitive impairment in the older adult population but continues to be underestimated and undetected in older people. This study aimed to examine the feasibility and acceptability of routine screening for alcohol misuse in a small sample of older people with cognitive impairment receiving services in memory clinics.

METHODS

This study employed a qualitative and exploratory design, using a convenience sample of individuals attending a memory clinic in England. Ten service users older than 65 with a diagnosis of cognitive impairment (i.e., mild cognitive impairment or dementia) took part in the study. Individuals who met inclusion criteria were invited to take part in an hour-long interview, which included the interviewer administering the alcohol screening tools. Interview transcripts were analyzed using thematic analysis.

RESULTS

Participants were able to engage with the screening tools and could, with assistance, complete them in a collaborative and timely manner without distress. All participants reported that these tools were acceptable as part of the clinic assessment. Administering the screening tools was not time-consuming or difficult, making their use feasible within the memory clinic setting. While there were some challenges (e.g., arithmetic, recall, language problems), these challenges could be overcome with the aid of the person administering the screening tool using standardized techniques for assessment administration.

CONCLUSIONS

Routine screening for alcohol misuse in older people with cognitive impairment receiving services in memory clinics is feasible and acceptable. The process of completing alcohol screening tools with older adults receiving services at memory clinics may increase awareness of the potential impact of alcohol on cognitive functioning and provide practitioners with an opportunity to educate service users about the ways that their drinking is affecting their memory. Several techniques to facilitate completion of screening tools were identified. Future research should evaluate the reliability and validity of alcohol screening tools with older people through corroborating screening results with other assessment methods.

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.

Alcohol diagnoses among older Tennessee Medicare beneficiaries: race and gender differences

BACKGROUND

These analyses bolster a sparse body of research focusing on the rate of alcohol disorders among older adults, particularly race and gender subgroups.

METHODS

We based the study on cross-sectional data from all Medicare billed physician/patient encounters. Analyses of these data included cross-tabulations, difference of means tests, and difference of proportions tests, logistic regression and multinomial logistic regression. These analyses were based Medicare billing records from physician/patient encounters in Tennessee. Data included Tennessee Medicare billings beneficiaries enrolled in Medicare Part B, who saw a physician at least once in 2000. Patients with billings containing ICD-9 codes: 303 (alcohol abuse), 305 (alcohol dependence), 291 (alcohol psychosis), or 571.1-571.3 (alcohol-related liver disease including cirrhosis of the liver) as to primary diagnosis were considered alcohol-disordered.

RESULTS

Analyses reveal the overall rate of alcohol disorders, subgroup variation in rates and differences in pattern of specific disorders. Merely 0.04% of Tennessee Medicare beneficiaries were diagnosed with any type of alcoholism, a rate much lower than those reported in previous studies. Rates of alcohol disorders varied across groups, with significantly higher rates for Black men. The type alcohol disorder also varied across groups.

CONCLUSIONS

Many encounters with the medical system result in missed opportunities to identify and treat alcohol disorders, a significant risk factor among older adults. Alcoholism both triggers and exacerbates many chronic conditions among older adults. The earlier in the disease trajectory the more of these conditions could be prevented or more efficiently managed, resulting in substantial savings in health care costs.

Factor structure of pain medication questionnaire in community-dwelling older adults with chronic pain

OBJECTIVES

This study was to develop a version of the Pain Medication Questionnaire (PMQ) specific to the elderly chronic pain population and to identify relevant subscales and items for that population. Exploratory factor analysis (EFA) was conducted to assess the factor structure of the PMQ, to eliminate items that are not appropriate for this population, and to improve ease of administration in the elderly population.

METHODS

Data were obtained through a survey administered to older adults with chronic pain who consumed opioid medications in a cross-sectional study at outpatient clinics affiliated with the Baltimore Veterans Affairs Medical Center and the University of Maryland Medical System. EFA was conducted on the PMQ in the geriatric chronic pain population, which was compared with the PMQ studies from the general chronic pain population.

RESULTS

A two-factor solution yielded Factor 1 with four items and Factor 2 with three items; 18 items did not load significantly on either factor, and only seven items loaded significantly on either factor. All of the chosen factor loadings ranged from 0.41 to 0.88.

CONCLUSION

  The findings suggest that, although a small number of the items were identified from the overall scale, they adequately explain two relatively unique factors pertaining to pain management among older adults. This preliminary study suggests that the seven-item PMQ may be useful in assessing opioid medication misuse in community-dwelling older adults with chronic pain. Future studies are needed to confirm the reliability, validity, and factor structure of this modified PMQ in the geriatric population.

Caring for the elderly female psychiatric patient

With the growth of the elderly population, and the female elderly population in particular, healthcare providers will see increasing numbers of elderly women with psychiatric disorders. To properly care for this group of patients, better understanding is needed not only of group differences in this patient population but also of the differences in each individual, as they age, given their unique life experiences, cohort effects, medical comorbidity, social situation, and personality traits. Understandably, these characteristics will interact with psychiatric disorders in ways that may increase the challenge to correctly diagnose and treat these patients. In addition, understanding late life changes, the prevalence of various mental disorders and the sometimes unique presentation of mental disorders in this age group is required to better diagnose and treat this population.

Unconventional indicators of drug dependence among elderly long-term users of benzodiazepines

A quarter of the elderly population is prescribed benzodiazepines (BZD). This has led to growing concerns about drug dependence and the validity of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) criteria for dependence to a substance. This study aimed to understand how dependence was experienced by long-term BZD users. Interviews were conducted with 45 elderly persons who had been using BZDs for an average of nine years. These users' comments suggest six indicators of dependence: self-identifying as a dependent user, invoking multiple stressors to justify BZD use, using BZD to cope with anticipated stressors, trivializing the dangers of BZDs, keeping a supply in reserve, having previously tried and failed to stop, and reducing the dosage. Our results stress the need to take a more elaborate, person-centered view of dependence.

Substance abuse integration in nursing education: an innovative collaborative model

This paper reports the outcomes of a 3-year faculty development project, the Nursing School Education Collaborative (NSEC), implemented in four baccalaureate schools of nursing. The focus of the NSEC was to strengthen educational programs through faculty development and curriculum integration in the area of substance abuse and addictions education. A comprehensive needs assessment process is outlined, and faculty development and curriculum integration activities are detailed. Faculty development has resulted in significant improvements in each school's substance abuse curriculum. Outcomes at each participating school have included continuing education activities, acquisition of additional teaching resources, the development of an integration model, and increased curriculum and clinical contact hours. With the increasing recognition of substance abuse as a number one public health problem and nursing as a major health workforce, this project serves as a model for replication.

Managing delirium and agitation in elderly hospitalized orthopaedic patients: Part I--Theoretical aspects

Managing behavioral disorders such as delirium and agitation while simultaneously attending to the acute needs of elderly patients is a challenge that confronts orthopaedic nurses on a daily basis. This will only increase in frequency and complexity as the new century dawns. Delirium and agitation affect morbidity, mortality, length of stay, and costs--in short, outcomes. To manage and care for these patients, orthopaedic nurses must first update their knowledge of acute disorders that can disrupt mental status and behavior, and the effects of systemic events on brain function. With the knowledge of the pathophysiology of delirium and agitation, nurses then need to refine their assessment and intervention skills. This article describes the phenomena of agitation and delirium in the elderly acute orthopaedic patient, outlines current perceptions regarding pathophysiology, and offers guidelines for prevention and intervention. An algorithm has been developed that can assist with the identification of at-risk individuals, causes of delirium, and early assessments in the acute care setting.
