Prevalence and course of psychiatric disorders among nursing home admissions

Prevalence of mental diseases in Austria : Systematic review of the published evidence

BACKGROUND

Addressing the growing burden of mental diseases is a public health priority. Nevertheless, many countries lack reliable estimates of the proportion of the population affected, which are crucial for health and social policy planning. This study aimed to collect existing evidence on the prevalence of mental diseases in Austria.

METHODS

A systematic review was conducted using MeSH, EMTREE and free-text terms in seven bibliographic databases. In addition, the references of included papers and relevant Austria-specific websites were searched. Articles published after 1996 pertaining to the Austrian adult population and presenting prevalence data for mental diseases were included in the analysis.

RESULTS

A total of 2612 records were identified in the database search, 19 of which were included in the analysis, 13 were community-based studies and 6 examined institutionalized populations. Sample sizes ranged from 200 to 15,474. The evidence was centered around depression (n = 6, 32%), eating disorders (n = 4, 21%) and alcohol dependence (n = 3, 16%). While most studies (n = 10, 53%) used questionnaires and scales to identify mental diseases, seven studies used structured clinical interviews, and two studies examined use of psychotropic drugs. Due to the diversity of methodologies, no statistical pooling of prevalence estimates was possible.

CONCLUSION

Information on the prevalence of mental diseases in Austria is limited and comparability between studies is restricted. A variety of diagnostic instruments, targeted populations and investigated diseases contribute to discrepancies in the prevalence rates. A systematic, large-scale study on the prevalence of mental diseases in Austria is needed for comprehensive and robust epidemiological evidence.

Diagnosed, identified, current and complete depression among patients attending primary care in southern Catalonia: different aspects of the same concept

The aims of this study were to explore the prevalence and the conceptualizations of depression detected by the healthcare system, identified by the patient or classified/identified in the validated Goldberg's questionnaire in a community. We conducted a cross-sectional evaluation of 317 patients. The different types of depression diagnosed, identified, current or total were stratified by age and gender groups. The difference in the conceptualization of depression from the medical or ordinary people point of view indicate that depression care requires the understanding of the lifestyle, beliefs, attitudes, family and social networks of the people the physicians and nurses care for.

Predisposing and Facilitating Factors of Severe Psychological Distress among Frail Elderly Adults

A sample of frail older adults (65 years and over) living at home or institutionalized (n = 664) with a significant functional limitation was used to document predisposing and facilitating factors of severe psychological distress among frail elderly adults. Our results indicated that 48.2 per cent of the older adults living at home presented severe psychological distress symptoms, compared to 34.3 per cent of elderly adults living in institutions. The probability of reporting a severe level of psychological distress was associated with the respondents' social support, cognitive and functional status. When the respondents' cognitive and functional status were controlled, no evidence of a significant association was found between the respondents' age, gender, marital status, education or income and the level of their psychological distress symptoms. Our results showed that 77.9 per cent of the respondents with severe psychological distress symptoms were still severely distressed 12 months after their first interview. Findings suggest that severe psychological distress represents an important challenge for practitioners in gerontology and geriatrics. It is suggested that other studies focusing on the consequences of psychological distress on older adults' quality of life, functional decline, institutionalization and mortality may help document the gravity of this symptomatology in the elderly population.

Psychogeriatric services in the community and in long-term care facilities: needs and developments

PURPOSE OF REVIEW

An increasing proportion of the world's population is over the age of 65 years. Specialist mental health services for older people have been developed in many countries. The way services develop depends partly on how healthcare arrangements have evolved in that jurisdiction, as well as on finances, culture and attitudes towards elderly and disabled individuals. Health planners in developing countries recognize that considerable increases in their elderly populations and numbers of individuals with disability are imminent. It will be important to ensure that older people with mental disorders receive appropriate treatment. This review discusses recent findings and observations about psychogeriatric services in the community and in long-term care facilities, and aims to suggest how to improve or develop such services.

RECENT FINDINGS

The prevalence of mental disorders in long-term care facilities is high, but services to deal with them are usually not optimal. When appropriately staffed and organized, community psychogeriatric services, day care and collaborative care can be effective in reducing mental health problems and preventing admissions.

SUMMARY

Recent reviews and research have provided useful guidance regarding aspects of current psychogeriatric services that work well and those that need to be improved. A person-centred approach is favoured.

Risk of nursing home admission in association with mental illness nationally in the Department of Veterans Affairs

OBJECTIVE

We sought to determine whether patients with mental health diagnoses in the Department of Veterans Affairs (VA) are more likely to be admitted to nursing homes and to identify sociodemographic, utilization, and clinical characteristics, especially indicators of mental illness severity, associated with nursing home admission among mentally ill patients.

METHODS

Patients receiving treatment in the VA system nationally during FY 2000 and having no evidence of nursing home utilization during FY 1999 or FY 2000 were followed through FY 2003 using administrative claims data. Three-year incidence rates and unadjusted odds ratios were estimated for each diagnosis. Logistic regression was used to examine the correlates of admission among mentally patients, including analyses stratified by age.

RESULTS

Of 3,952,229 VA patients with no prior nursing home use, 15.2% received a mental health diagnosis, of which, 4.6% were eventually admitted to a nursing home. Among mentally ill patients, risk of admission was highest for those with any inpatient medical/surgical days (odds ratio [OR] = 2.28), followed by 3+ outpatient medical visits (OR = 1.48), inpatient mental health days (OR = 1.31), and outpatient mental health visits (OR = 1.09). Patients diagnosed with dementia were 58% more likely to be admitted. Patients diagnosed schizophrenia (OR = 1.26), other psychosis (OR = 1.15), and personality disorder (OR = 1.14) had the next highest probabilities. Elderly patients with bipolar disorder (OR = 1.28) were also more likely to enter.

CONCLUSION

Although factors leading to nursing home entry among the mentally ill are similar to those driving entry in the general population, those with more severe mental health problems are still more likely to be admitted.

Prevalence of dementia in the elderly in Europe

Dementia is an important public health problem as it is one of the most common diseases in the elderly and a major cause of disability and mortality. This review on dementia is restricted to European Union countries where the overwhelming majority of studies have been undertaken, and will also refer to the EURODEM publications which may be considered to be the principal European reference point in this area. In subjects aged over 65, crude prevalence rates for dementia varied between 5.9% and 9.4%. We discuss the major problems limiting the use of these estimations, limits which may differ according to the area of application, be it etiological research or care provision.

Not less but different: psychotropic drug utilization trends in Norwegian nursing homes during a 12-year period. The Bergen District Nursing Home (BEDNURS) Study

BACKGROUND AND AIMS

The use of psychotropic drugs in nursing homes is generally considered to be inappropriately high. The aim of the present survey was to compare psychotropic drug use in nursing homes (NHs) in 1985 relative to 1996/97, and to explore predictors for this drug use.

METHODS

Cross-sectional study. Mental capacity was assessed by means of the Clinical Dementia Rating scale (CDR), and behavior registered by trained nurses. Scheduled, daily use of psychotropic drugs among long-term care residents in 1985 (N=1247) and 1996/97 (N=1035) was recorded. Bivariate analyses and logistic regression analyses were applied to establish predictors for psychoactive drug use.

RESULTS

From 1985 to 1996/97, the proportion of residents using any psychotropic drug increased from 52 to 57%. Antipsychotic drug use decreased from 33 to 22%, while anxiolytics increased from 11 to 16%, hypnotics from 11 to 14%, and antidepressants from 12 to 31%. Psychotropic drug use was predominantly associated with behavioral symptoms and not with mental impairment. Concurrent use of two or more psychotropic drugs increased from 23 to 32% of all psychotropic users.

CONCLUSIONS

During the study period, a substantial decline in the use of antipsychotics was observed, but a generally increased overall use of psychotropic drugs, particularly antidepressants. Psychotropic drug treatment was mainly associated with behavioral symptoms.

Cost-effectiveness analysis of pharmaceutical care in a medicare drug benefit program

OBJECTIVES

Although there has recently been substantial interest in a Medicare drug benefit program, little attention has focused on ensuring improved access to medication monitoring for Medicare beneficiaries. Using a societal perspective, we evaluated the impact pharmacists could have on inappropriate prescribing, patient compliance, and medication-related morbidity and mortality within a Medicare drug benefits program.

METHODS

A cost-effectiveness analysis from a societal perspective was performed. A comprehensive MEDLINE search for relevant literature identified data sources and model parameters.

RESULTS

In the base case, a pharmaceutical care benefit in the elderly population would cost US dollars 2100 (year 2000 prices) per life-year saved, which is highly cost-effective. Reasonable changes in model parameters did not raise the cost-effectiveness ratio above US dollars 13000 per life-year saved.

CONCLUSION

Despite limitations in both the quantity and the specificity of data available, pharmaceutical care appears to be a highly cost-effective augmentation to a Medicare drug benefit program. This result is robust to model parameter changes. This model is conservative in that it does not include ongoing benefits from medication monitoring or increased elderly drug utilization and polypharmacy as the Medicare drug program is phased in.

The prevalence, diagnosis and treatment of depression in dementia patients in chronic care facilities in the last six months of life

OBJECTIVE

To assess the prevalence, diagnosis and treatment of depression among dementia patients and normal controls in chronic care facilities in the last six months of life.

METHOD

We reviewed perimortal data concerning dementia severity, depressive symptoms and diagnoses, and medication use for 279 dementia patients and 24 normal controls brought to autopsy through an Alzheimer's Disease Resource Center.

RESULTS

Major depression was highly prevalent among both dementia patients and normal controls in chronic care facilities in the last six months of life. This depression was under-diagnosed by physicians. Documentation of depressive symptoms by medical support staff has improved over time. However, physician diagnosis of depression has not improved. Recognition of depression was significantly lower for patients with severe dementia. Depression was under-treated in both dementia patients and normal controls, although treatment rates may be increasing. Anxiolytics and hypnotics were often used in lieu of, or in addition to, antidepressant therapy.

CONCLUSIONS

Major depression was highly prevalent in both dementia patients and normal controls, indicating that depression is an important issue for the elderly in the last six months of life irrespective of cognitive status. Under-diagnosis of depression may be an important clinical issue. As physician diagnosis of depression has not improved with time, further physician training and/or awareness initiatives may be warranted. Depression, a treatable cause of excess morbidity and mortality, was undertreated in all groups studied. However, treatment rates may be improving. The prevalent use of anxiolytics and hypnotics for depressed patients is problematic.
