The Elderly

Late life depression is common and associated with disability, reduced quality of life, mortality, and high health care costs. Depressed older adults frequently have comorbid medical illnesses and cognitive impairment, but relatively little is known about the diagnosis and treatment of depression in the face of these comorbid conditions. Only a minority of depressed older adults receive specialty mental health care and most depression care is provided in primary care where few receive effective treatment. Very little is known about the epidemiology and quality of care for bipolar disorder in late life. Additional research should focus on the quality and outcomes of care for older adults with affective disorders in diverse settings (including primary care, specialty mental health care, home health care, nursing homes, and assisted living facilities) and on the care of older adults who have affective disorders and comorbid medical disorders, dementia, substance use disorders, or chronic pain.     

Diagnosis and treatment of older adults with depression in primary care.

This article provides an overview of current challenges in the diagnosis and treatment of depressed older adults in primary care and considers suggestions for clinicians, researchers, and policy makers to improve care for this population. Despite the enormous toll of depression on individuals and society and the availability of effective treatments, depressed older adults remain largely untreated or undertreated. They rarely see mental health professionals, but have relatively frequent contact with primary care providers. In primary care, the chronic and recurrent nature of depression and a number of patient, provider, and policy-related barriers interfere with effective depression treatment. Recent research suggests that improving care for individuals with late life depression will require education and engagement of older adults and their primary care providers as active partners in caring for depression. It will also require additional human resources and systematic models of care dedicated to proactively managing depression as a chronic illness. Finally, it will require training of mental health professionals to effectively collaborate with their colleagues in primary care in treating depressed older adults. Further improvement in depression care would likely result from the implementation of true parity for mental health treatments for older adults.     

Advances in the treatment of depression in older adults

Depressive symptoms in older adults are common, but the minority of elderly meet criteria for major depressive disorder. This has led to confusion regarding the recognition of diagnosis, approach to treatment, and monitoring of outcomes in this needy population. Few depressed older adults are willing to seek treatment from psychiatrists or mental health specialists. Treatment approaches to the depressive spectrum of disorders in late life, which encompasses major and minor depressive disorder, dysthymic disorder, and mood disorders related to medical conditions, must include evidence-based algorithms that can be delivered in a variety of health care settings. Several recent multisite trials have advanced the use of collaborative care models and the systematic stepwise approach to the treatment of depression and anxiety states in older adults. This offers the ability to provide effective treatment of depression for older adults, consistent with current guidelines, in primary care and specialized health care settings.     

Evidence-based practices in geriatric mental health care

The past decade has seen dramatic growth in research on treatments for the psychiatric problems of older adults. An emerging evidence base supports the efficacy of geriatric mental health interventions. The authors provide an overview of the evidence base for clinical practice. They identified three sources of evidence-evidence-based reviews, meta-analyses, and expert consensus statements-on established and emerging interventions for the most common disorders of late life, which include depression, dementia, substance abuse, schizophrenia, and anxiety. The most extensive research support was found for the effectiveness of pharmacological and psychosocial interventions for geriatric major depression and for dementia. Less is known about the effectiveness of treatments for the other disorders, although emerging evidence is promising for selected interventions. Empirical support was also found for the effectiveness of community-based, multidisciplinary, geriatric psychiatry treatment teams. The authors discuss barriers to implementing evidence-based practices in the mental health service delivery system for older adults. They describe approaches to overcoming these barriers that are based on the findings of research on practice change and dissemination. Successful approaches to implementing change in the practices of providers emphasize moving beyond traditional models of continuing medical education to include educational techniques that actively involve the learner, as well as systems change interventions such as integrated care management, implementation toolkits, automated reminders, and decision support technologies. The anticipated growth in the population of older persons with mental disorders underscores the need for a strategy to facilitate the systematic and effective implementation of evidence-based practices in geriatric mental health care.     

Caring for mental illness in the United States: a focus on older adults.

OBJECTIVE: The authors compared rates of common mental disorders and the use of primary care and specialty mental health services among younger and older adults. METHODS: They used data from 9,585 respondents to the HealthCare for Communities (HCC) Household Telephone Survey. Mental disorders during the past year, including depression, dysthymia, and generalized anxiety disorder, were identified with a short questionnaire. The survey also collected information about sociodemographic and insurance status, perceived need for mental health care, and use of health services. RESULTS: Older adults (age 65 and older) were significantly less likely than younger adults (18-29) or middle-aged adults (30-64) to meet diagnostic criteria for a mental disorder (8% versus 15% in each of the younger age-groups). Older adults who met diagnostic criteria for mental disorders were less likely to perceive a need for mental health care, to receive specialty mental health care or counseling, or to receive referrals from primary care to mental health specialty care than young or middle-aged adults. CONCLUSION: Few older adults with mental disorders use mental health services, particularly specialty mental health services. The lack of perceived need for mental health care may contribute to low rates of mental health service use among older adults.     

Caring for depressed and suicidal older patients: a survey of physicians and nurse practitioners

OBJECTIVE: This study sought to describe patterns of mental health care for depressed and suicidal geriatric patients by primary care physicians (MDs) and nurse practitioners (NPs). METHODS: A probability sample of 300 Illinois MDs from the AMA Physician Masterfile and a national sample of 595 NPs from the American Academy of Nurse Practitioners were surveyed. Sixty-three percent of MDs and 61 percent of NPs responded regarding their approaches to assessing, treating, and referring older adult patients who were depressed or suicidal. Respondents rated their confidence in assessing and treating depression and suicidality and identified barriers to mental health treatment in a primary care setting. RESULTS: Both similarities and differences were found among MDs and NPs in their patterns of managing depressed and suicidal older adults. NPs used more varied approaches in assessing, treating, and referring their geriatric patients with mental health problems. MDs relied more heavily on psychotropic medications for the treatment of depression and on psychiatrists when referring suicidal older patients. NPs were more likely than MDs to note lack of training and referral resources as barriers to treating depression of older patients. NPs rated their training in geriatric mental health more favorably than MDs. CONCLUSIONS: In terms of assessment of depression, preferred treatment approaches, the use of referral resources, and perceived barriers to mental health care, there appears to be a greater orientation towards a psychosocial approach among NPs. Primary care MDs and NPs often have different perspectives that in combination could enhance the mental health care of geriatric patients.     

Mapping Movement: Applying Motion Measurement Technologies to the Psychiatric Care of Older Adults

Purpose of Review

Recent advances in technology have changed the landscape of treatment for adults with mental illness. This review highlights technological innovations that may improve care for older adults with mental illness and neurocognitive disorders through the measurement and assessment of physical motion. These technologies include wearable sensors (such as smart watches and Fitbits), passive motion sensors, and smart home models that incorporate both active and passive motion technologies.

Recent Findings

Clinicians have evaluated motion measurement technologies in older adults with depression, dementia, anxiety, and schizophrenia. Results from studies in dementia populations suggest that motion measurement technologies can assist clinicians in diagnosing dementia earlier through the evaluation of gait, balance, and postural kinematics. Motion detection technologies can also be used to identify mood episodes at an earlier stage by detecting subtle behavioral changes.

Summary

Clinicians may use the objective data provided by technologies such as accelerometers to identify illnesses earlier, which may inform treatment decisions. The data may be used as a suitable surrogate marker for detecting depression in older adults, predicting the likelihood of falls, or quantifying physical activity in older adults with chronic mental illnesses or anxiety. Motion-based technologies also have the potential to detect physical activity for older adults residing in nursing homes. Wearable technologies are generally well tolerated in older adults, although the use of new technology and electronic health data could involve privacy and security concerns among this vulnerable population.

     

A tiered model of psychogeriatric service delivery: an evidence-based approach

BACKGROUND: Previous models of mental health care for older persons have not considered the full spectrum of mental disorders. AIM: To describe a tiered model for comprehensive evidence-based planning of service delivery for mental disorders in late life. METHOD: The model depicts tiers of mental disorders in ascending order of severity and consequent interventions required. RESULTS: Interventions aim both to avert individuals from moving up tiers (prevention) and to move individuals down tiers (treatment). Individuals in the lower tiers have no mental disorders and prevention strategies are targeted at known risk factors. In the middle tiers, individuals with mild-moderate mental disorders will mainly be treated in primary care, often in collaboration with specialist mental health services for older people. Individuals in the top tiers with severe mental disorders usually require institutional care. CONCLUSION: The tiered model provides a basis for planning comprehensive service delivery.     

Characteristics of older adults referred to a psychiatric emergency outreach service

Although older adults typically underutilize mental health services, problems associated with dementing illnesses, chronic medical illnesses, affective disorders, social isolation, and multiple medication use, among other phenomena, have increased referrals of the elderly to psychiatric emergency services. The present study reviewed characteristics of elderly adults referred to a psychiatric emergency outreach/screening service. Of all individuals for whom a referral was made, 24% were aged 60 or older. Among those older adults referred, 63% were seen by screening service personnel; 37% did not meet screening criteria or voluntarily sought mental health services. Diagnoses of individuals evaluated included dementia (27%), affective disorders (27%), schizophrenia (16%), psychosis (12%), alcohol abuse (7), and diagnosis deferred (11%). Findings highlight the limited options available for mental health care of the aged.     

Improving access to geriatric mental health services: a randomized trial comparing treatment engagement with integrated versus enhanced referral care for depression, anxiety, and at-risk alcohol use

OBJECTIVE: The authors sought to determine whether integrated mental health services or enhanced referral to specialty mental health clinics results in greater engagement in mental health/substance abuse services by older primary care patients. METHOD: This multisite randomized trial included 10 sites consisting of primary care and specialty mental health/substance abuse clinics. Primary care patients 65 years old or older (N=24,930) were screened. The final study group consisted of 2,022 patients (mean age=73.5 years; 26% female; 48% ethnic minority) with depression (N=1,390), anxiety (N=70), at-risk alcohol use (N=414), or dual diagnosis (N=148) who were randomly assigned to integrated care (mental health and substance abuse providers co-located in primary care; N=999) or enhanced referral to specialty mental health/substance abuse clinics (i.e., facilitated scheduling, transportation, payment; N=1,023). RESULTS: Seventy-one percent of patients engaged in treatment in the integrated model compared with 49% in the enhanced referral model. Integrated care was associated with more mental health and substance abuse visits per patient (mean=3.04) relative to enhanced referral (mean=1.91). Overall, greater engagement was predicted by integrated care and higher mental distress. For depression, greater engagement was predicted by integrated care and more severe depression. For at-risk alcohol users, greater engagement was predicted by integrated care and more severe problem drinking. For all conditions, greater engagement was associated with closer proximity of mental health/substance abuse services to primary care. CONCLUSIONS: Older primary care patients are more likely to accept collaborative mental health treatment within primary care than in mental health/substance abuse clinics. These results suggest that integrated service arrangements improve access to mental health and substance abuse services for older adults who underuse these services.     

Consensus statement on the upcoming crisis in geriatric mental health: research agenda for the next 2 decades

It is anticipated that the number of people older than 65 years with psychiatric disorders in the United States will increase from about 4 million in 1970 to15 million in 2030. The current health care system serves mentally ill older adults poorly and is unprepared to meet the upcoming crisis in geriatric mental health. We recommend the formulation of a 15- to 25-year plan for research on mental disorders in elderly persons. It should include studies of prevention, translation of findings from bench to bedside, large-scale intervention trials with meaningful outcome measures, and health services research. Innovative strategies are needed to formulate new conceptualizations of psychiatric disorders, especially those given scant attention in the past. New methods of clinical and research training involving specialists, primary care clinicians, and the lay public are warranted.     

Anxiety disorders in older adults: a comprehensive review

This review aims to address issues unique to older adults with anxiety disorders in order to inform potential changes in the DSM‐V. Prevalence and symptom expression of anxiety disorders in late life, as well as risk factors, comorbidity, cognitive decline, age of onset, and treatment efficacy for older adults are reviewed. Overall, the current literature suggests: (a) anxiety disorders are common among older age individuals, but less common than in younger adults; (b) overlap exists between anxiety symptoms of younger and older adults, although there are some differences as well as limitations to the assessment of symptoms among older adults; (c) anxiety disorders are highly comorbid with depression in older adults; (d) anxiety disorders are highly comorbid with a number of medical illnesses; (e) associations between cognitive decline and anxiety have been observed; (f) late age of onset is infrequent; and (g) both pharmacotherapy and CBT have demonstrated efficacy for older adults with anxiety. The implications of these findings are discussed and recommendations for the DSM‐V are provided, including extending the text section on age‐specific features of anxiety disorders in late life and providing information about the complexities of diagnosing anxiety disorders in older adults.

The Mental Health of Older LGBT Adults

There are approximately one million older lesbian, gay, bisexual, and transgender (LGBT) adults in the USA. Their mental health issues result from interactions between genetic factors and stress associated with membership in a sexual minority group. Although advancements in acceptance and equal treatment of LGBT individuals have been occurring, sexual minority status remains associated with risks to physical and mental well-being. Older LGBT adults are more likely to have experienced mistreatment and discrimination due to living a majority of their lives prior to recent advancements in acceptance and equal treatment. All LGBT adults experience one common developmental challenge: deciding if, when, and how to reveal to others their gender identity and/or sexual orientation. LGBT individuals have higher rates of anxiety, depression, and substance use disorders and also are at increased risk for certain medical conditions like obesity, breast cancer, and human immunodeficiency virus (HIV). Improved education and training of clinicians, coupled with clinical research efforts, holds the promise of improved overall health and life quality for older LGBT adults.     

Engaging an Asian Immigrant Older Adult in Depression Care: Collaborative Care,Patient-Provider Communication and Ethnic Identity

Minority older adults face multiple barriers when trying to access mental health services and often present with more severe symptoms of mental health conditions. We describe the multilevel factors that contributed to the engagement of an Asian immigrant older adult with depression. Systems-level innovations such as collaborative care in primary care can increase access to care for all, including minority older adults; however, one size fits all interventions may not meet the needs of communities of older adults with different life experiences, language needs, norms and values regarding help-seeking for mental health. Health outcomes remain unequal , suggesting the need to tailor interventions for minority older adults. For the patient, specific factors related to language and ethnic concordance between patient and healthcare provider, communication behaviors, ethnic identity, and social norms may be important to take into account. The recognition of the heterogeneity of patients and the limitations of cultural competence approaches defined as broad, general knowledge about ethnic cultures may be needed. A need to learn continuously from clinical experience and adopt a patient-oriented model of communication and decision-making may successfully engage Asian immigrant older adults in depression care services.     

Detection of depression and anxiety disorders by home care nurses

Several studies have reported that psychiatric disorders, mainly depression and anxiety disorders, were masked and undiagnosed among older adults, particularly frail elderly. This phenomenon could have a significant impact on elderly quality of life. In this study, we assessed the utility of three measures for detecting mental health disorders among frail elderly receiving home care services: (1) the PRIME-MD; (2) a standard psychological distress measure (PDI-29), and (3) the health care case manager'sa priori judgment on the subject's mental health status. Results obtained by home care nurses were compared to those obtained by clinical psychologists using a structured diagnostic interview (SCID for DSM-IV). The study was conducted in two community health service centres. During the study's period, all patients in the health care workers' caseload without cognitive impairment and not reporting significant stressful life events during the six-week period preceding the interview (n = 315) were asked to participate in the study. Results showed that 42.9% of the volunteers that agreed to meet a psychologist at home (n = 177) had a current SCID-IV diagnosis. The specificity of the PRIME-MD test performed by nurses was 83.8% and its sensitivity was 41.7%. The correct classification rate was 66.7%. Results indicated that the PDI-29 items showed better performance characteristics than the PRIME-MD in identifying current cases. The specificity of the PDI-29 was 59.0% and its sensitivity was 73.6%. These results lead us to the conclusion that the PRIME-MD, previously proposed by Spitzer, R.L., Williams, J.B., Kroenke, K., Linzer, M., DeGruy, F.V. 3rd, Hahn, S.R., et al. (1994, Utility of a new procedure for diagnosing mental disorders in primary care. The PRIME-MD 1000 study. Journal of the American Medical Association, 272 (22), 1749-1756.) to help physicians in primary care clinics, could be less appropriate than the PDI-29 when used by home care nurses in identifying undiagnosed mental health disorders in frail older adults living at home. Moreover, this study showed that the health care case manager'sa priori judgment on the care receiver's mental health status is not sufficient in identifying frail elderly mental health services needs. A two-stage screening procedure is proposed to help home care nurses.     

A national survey of care for persons with co-occurring mental and substance use disorders

OBJECTIVE: The delivery of appropriate treatment to persons who have mental and substance use disorders is of increasing concern to clinicians, administrators, and policy makers. This study sought to describe use of appropriate mental health and comprehensive substance abuse care among adults in the United States with probable co-occurring disorders. METHODS: Data from the Healthcare for Communities survey, which is based on a national household sample studied in 1997 and 1998, were used to identify individuals who had probable co-occurring mental and substance use disorders. The sociodemographic and clinical characteristics of these individuals and their use of services were recorded. Logistic regression analysis was used to identify variables associated with receipt of mental health and substance abuse treatment and with receipt of appropriate treatment. RESULTS: Estimates for the U.S. adult population based on the weighted survey data indicated that 3 percent of the population had co-occurring disorders. Seventy-two percent did not receive any specialty mental health or substance abuse treatment in the previous 12 months; only 8 percent received both specialty mental health care and specialty substance abuse treatment. Only 23 percent received appropriate mental health care, and 9 percent received supplemental substance abuse treatment. Perceived need for treatment was strongly associated with receipt of any mental health care and with receipt of appropriate care. CONCLUSIONS: Despite the availability of effective treatments, most individuals who had co-occurring mental health and substance use problems were not receiving effective treatment. Efforts to improve the care provided to persons who have co-occurring disorders should focus on strategies that increase the delivery of effective treatment.     

The prevalence and outcome of depression and dementia in Botany's elderly population

BACKGROUND: Large epidemiological studies of adult populations have reported depression to be less prevalent in old age than among younger adults, whereas studies limited to older persons have reported rates that vary considerably, some showing high rates of depression. There was, therefore, reason to check data from a study that reported high rates, and to review evidence in relation to diagnosis and outcome. METHOD: Re-examination of data from a 1985 survey of elderly people living at home (n = 146). Depression and cognitive impairment were also assessed in a local hostel (n = 42) and nursing home (n = 74). DSM diagnoses were made by an old age psychiatrist. In the nursing home, 23 other residents could not respond to interview questions but were considered to have severe dementia. Subjects in all three settings were followed up after 4 years. RESULTS: Seven community subjects (4.5%; confidence interval 1.3-8.3%) and three in residential care fulfilled criteria for major depression. The estimated total prevalence of depressive disorders among elderly in Botany was between 13.0 and 13.6% (4.6% major depression, 3.6% dementia with depression, 5.4% other depressive disorders). In 1985, the prevalence of dementia among those living at home was 11%. Four-year mortality in the dementia cases was 60%. CONCLUSIONS: Botany has a high prevalence of dementia and depression among elderly people. The recent cross-age. Australian study of mental health and well-being provided an inaccurate report concerning the pattern of mental disorders in old age.     

Late-life anxiety disorders among Puerto Rican primary care patients: impact on well-being, functioning, and service utilization

With the growing population of older Hispanic adults there is a need for additional research on the mental health care of this patient group. This study explored the impact of anxiety disorders on the health status of 291 older (>/=50 years) Puerto Rican primary care patients (n = 65 with anxiety disorders, n = 226 without anxiety disorders). All analyses controlled for potential confounding variables, including depression diagnosis and physical health burden. Logistic regression indicated that anxiety disorders were associated with higher psychological distress, suicidality, and emergency room service utilization, as well as lower instrumental functioning and perceived health quality. Analysis of covariance indicated that both anxiety disorder status and history of ataque de nervios were related to higher percentages of lifetime somatic symptoms. These data highlight the need for improved recognition and treatment of anxiety disorders in older Puerto Rican adults.     

Psychiatric and Medical Comorbidity in the Primary Care Geriatric Patient—An Update

The mental health needs of older primary care patients are now widely recognized if not widely addressed. The range of behavioral health approaches including co-locating psychiatrists and integrating mental health professionals as care managers into primary care sites is extensive and growing. Nonetheless the primary care provider remains the first line of defense against mental disorders, most commonly depression and anxiety that accompany and exacerbate common physical conditions. The excess, potentially avoidable disability that results from comorbidity makes it imperative that early recognition and evidence based intervention occur. Multi-morbidity and polypharmacy make intervention a challenge. Psychotherapy can help overcome comorbidity depression however the most accessible intervention would be an antidepressant FDA approved for both anxiety and depressive disorders. For all these reasons, a focus on physical conditions most commonly associated with mental disorders can foster early recognition before the older patient’s care becomes overwhelmingly complicated.     

Lessons From Geriatric Psychiatry in the Long Term Care Setting

Of all long term care settings, the nursing home has served as the most productive laboratory for the study of the mental health problems of late life. Lessons from geriatric psychiatry research and practice in the nursing home have relevance to general psychiatry and to other health care settings, informing us about (a) psychiatric disorders in medically ill and disabled populations; (b) subsyndromes and subtypes of depression; (c) behavioral disturbances in patients with brain injury; (d) the effects of government regulation and education on mental health care; and (e) essential roles for psychiatrists in changing health care systems. Selected areas of knowledge based on geriatric psychiatry research and experience in long term care are reviewed in this paper, and their applications for the field of psychiatry in general are explored.
