Long-term effects of childhood abuse on the quality of life and health of older people: results from the Depression and Early Prevention of Suicide in General Practice Project

OBJECTIVES

To determine whether childhood physical and sexual abuse are associated with poor mental and physical health outcomes in older age.

DESIGN

Cross-sectional, postal questionnaire survey.

SETTING

Medical clinics of 383 general practitioners (GPs) in Australia.

PARTICIPANTS

More than 21,000 older adults (aged > or = 60) currently under the care of GPs participating in the Depression and Early Prevention of Suicide in General Practice (DEPS-GP) Study. Participants were divided into two groups according to whether they acknowledged experiencing childhood physical or sexual abuse.

MEASUREMENTS

Main outcome measures targeted participants' current physical health (Medical Outcomes Study 12-item Short Form Survey, Version 2 and Common Medical Morbidities Inventory) and mental health (Patient Health Questionnaire-9 and Hospital Anxiety and Depression Scale).

RESULTS

One thousand four hundred fifty-eight (6.7%) and 1,429 participants (6.5%) reported childhood physical and sexual abuse, respectively. Multivariate models of the associations with childhood abuse indicated that participants who had experienced either childhood sexual or physical abuse had a greater risk of poor physical (odds ratio (OR)=1.35, 95% confidence interval (CI)=1.21-1.50) and mental (OR=1.89, 95% CI=1.63-2.19) health, after adjustments. Older adults who reported both childhood sexual and physical abuse also had a higher risk of poor physical (OR=1.60, 95% CI=1.33-1.92) and mental (OR=2.40, 95% CI=1.97-2.94) health.

CONCLUSION

The effects of childhood abuse appear to last a lifetime. Further research is required to improve understanding of the pathways that lead to such deleterious outcomes and ways to minimize its late-life effects.

Deliberate self-harm in older adults: a review of the literature from 1995 to 2004

BACKGROUND

The prevention of suicide is a national and international policy priority. Old age is an important predictor of completed suicide. Suicide rates in old age differ markedly from country to country but there is a general trend towards increasing rates with increasing age. In 1996 Draper reviewed critically the evidence on attempted suicide in old age in the 10 years between 1985 and 1994. The review highlighted a need for prospective controlled studies in older people with more representative samples as well as studies examining the interaction of risk factors, precipitants, motivations, psychopathology and response to treatment. The aim of this paper is to update this review and to summarise the advances in our understanding of DSH in later life.

METHOD

We have critically reviewed relevant studies published between 1995 and 2004 to summarise the advances in our understanding of factors associated with deliberate self-harm in later life.

RESULTS

The main advances in understanding have been to clarify the effect of personality and cultural factors, service utilisation pre and post attempt, and the (lesser) impact of socio-economic status and physical illness. Methodological weaknesses continue to include inadequate sample sizes performed on highly selected populations, inconsistent age criteria and lack of informant data on studies relating to role of personality.

CONCLUSIONS

Future studies should include prospective, cross-cultural research with adequate sample sizes and which are population-based. Such approaches might confirm or refute the results generated to date and improve knowledge on factors such as the biological correlates of deliberate self-harm, service utilisation, costs and barriers to health care, and the interaction of these factors. Intervention studies to elucidate the impact of modifying these factors and of specific treatment packages are also needed.

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.

What is the effectiveness of acute hospital treatment of older people with mental disorders?

AIM

To appraise the effectiveness of acute hospital service delivery in old age psychiatry.

METHOD

A systematic literature search of the Medline, PsycINFO, CINAHL, EMBASE and Cochrane Collaboration databases was undertaken to obtain articles published in English from 1966 to May 2004 about old age psychiatry services. Articles were excluded if they did not focus on subjects over 60 years of age, did not include quantitative data on outcomes, or if the intervention was purely pharmacological or a specific non-pharmacological technique. The two authors independently assessed data quality. The overall quality of the evidence for the effectiveness of old age mental health service delivery was rated on an evidence hierarchy that has four levels of evidence.

RESULTS

Forty-six studies were identified that met our criteria. The only randomized controlled trials (RCTs) were of consultation/liaison service provision and delirium prevention and hence the best quality evidence is for interventions to prevent delirium, reduce costs and length of stay (LOS) in medical wards (level II). There is lower quality (level III/IV), albeit consistently positive, evidence that acute hospital treatment by old age psychiatry services is effective. By contrast, there is no evidence (level I) that non-psychiatric hospital medical services improve mental health outcomes.

CONCLUSION

There are gaps in our knowledge regarding the effectiveness of acute hospital treatment of mental disorders in old age. Multicenter studies involving comparisons of day hospitals, multidisciplinary community teams and acute hospital settings (old age mental health and adult mental health, with and without post-discharge community care) are required.

Vocally disruptive behaviour in dementia: development of an evidence based practice guideline

Vocally Disruptive Behaviour (VDB) is a term that includes screaming, abusive language, moaning, perseveration, and repetitive and inappropriate requests. It is one of the most challenging behaviours for nursing home staff, caregivers for people with dementia, and other nursing home residents. As with other behavioural disturbances, multiple causal factors have been identified in the literature and individual cases may have a number of interacting factors. There is a lack of consensus about how to treat VDB. Systematic treatment studies are few and there is a lack of empirical data supporting the effectiveness of specific interventions commonly used in clinical practice. This hinders clinicians and may result in the use of inappropriate treatments. Our aim was to systematically review the literature in order to develop a practice guideline for the assessment and management of VDB. The review will examine the typology, risk factors and management of VDB.

The prevalence of "cognitive impairment no dementia" in community-dwelling elderly: a pilot study

OBJECTIVE

To determine the prevalence of "cognitive impairment no dementia" (CIND) and "amnestic mild cognitive impairment" (aMCI) in a population sample of 70-79-year-olds and the risk factors for CIND.

METHOD

Cross sectional population survey.

SETTING

Sutherland Shire, Sydney, Australia.

SUBJECTS

150 community-dwelling 70-79-year-olds were screened by telephone, 42 of whom were assessed at home.

MEASURES

Demographics, subjective ratings of physical and emotional health and memory, cardiovascular risk factors, medications, the Mini-Mental State Examination, Boston Naming Test, Trail Making Tests A and B, Block Design, Rey Auditory Verbal Learning Test (RAVLT), Visual Reproduction, Logical Memory, letter and category fluency, the National Adult Reading Test (NART), the Geriatric Depression Scale (GDS) and the "state" section of the State-Trait Anxiety Inventory (STAI-S).

RESULTS

From the 400 subjects contacted initially, 150 consented to be interviewed and 131 eligible subjects were recruited. Of a 1-in-3 random sample of 42 subjects assessed at home, 14 (33.3%) subjects met criteria for CIND, 1 (2.4%) had possible dementia and the 27 remaining (64.3%) were cognitively normal. Four (9.5%) met criteria for aMCI. Subjects with CIND were older, had lower ranking occupations and were less likely to be currently working than those classified as cognitively normal. Ten subjects with CIND did not meet criteria for aMCI because they lacked subjective memory impairment (n = 3) or had cognitive deficits other than memory (n = 7). All subjects with aMCI met criteria for CIND.

CONCLUSIONS

One-third of individuals in this population sample met criteria for CIND. CIND is a broader definition than aMCI. Further research is needed to determine the longitudinal course and clinical utility of these definitions of cognitive impairment.

The prevalence of depressive symptoms among elderly Chinese private nursing home residents in Hong Kong

BACKGROUND

Privately-owned Nursing homes (PNH) in Hong Kong present a unique setting of institutional care where elderly with the whole spectrum of health status live together.

OBJECTIVES

This cross-sectional descriptive study aimed to determine the prevalence of significant depressive symptoms in a group of Cantonese-speaking Chinese private nursing home elderly living in Hong Kong, and to identify associated psychosocial and health factors. METHODOLOGICAL RESULTS: Two hundred and forty five residents fulfilled the inclusion criteria. Using the Chinese version of the Geriatric Depression Scale--Short Form (GDS-SF), we detected significant depressive symptoms in 29% of subjects. Univariate analysis revealed some associated socio-economic risk factors including current non-Comprehensive Social Security Assistance (CSSA) recipients, education levels and low abilities for social activities. Low vision, swallowing difficulties and low levels of basic activities of daily living (BADL) as reflected by the total Modified Barthel Index of less than 61 were important health predictors. Depression was also associated with features of self-perception of financial inadequacy, life dissatisfaction, poor self-perceived health, poor attitudes towards living arrangement and suicidal thoughts. Stepwise logistic regression identified swallowing problems, current non-CSSA recipient and low BADL ability as independent risk factors.

CONCLUSION

The high prevalence of depressive symptoms in the nursing home elderly requires the attention of Government authorities, health care and social service providers.

The relationship between self-destructive behaviour and nursing home environment

The aim of this study was to explore the relationship between self-destructive behaviour and nursing home environment. We performed a cross-sectional study comprising 647 residents in 11 nursing homes in Sydney, Australia using the Harmful Behaviours Scale (HBS), Abbreviated Mental Test Scale and the Resident Classification Index. The Directors of Nursing completed a questionnaire that rated physical design, staff and resident characteristics and demographics were obtained from nursing home records. On regression analysis a greater number of design features for frail and residents with dementia in general, and increased security measures were associated with greater HBS total score and risk-taking and passive self-harm subscales. A residential environment in which the residents were more functionally dependent and more likely to be in a shared room, managerial policies less geared towards managing difficult behaviour and less staff availability and training were associated with the 'uncooperativeness' factor. There were no significant predictors of the other two factors. The relationship between nursing home environment and self-destructive behaviours and the environment is complex and there needs to be an individualized approach to placement.

Nursing home staff attitudes towards residents with dementia: strain and satisfaction with work

BACKGROUND

Occupational and resident characteristics affect levels of staff stress and satisfaction in nursing homes, and levels of staff turnover are high. Working with more cognitively impaired residents, especially on day shift, is associated with high levels of stress in nursing home staff. Workload is highly predictive of the experience of burden and job pressure, while these outcomes vary according to whether staff work full- or part-time.

AIMS

To investigate the attitudes of nursing home staff towards residents, strain related to dementia care and satisfaction with work and their associations with demographic, occupational and behavioural disturbance in the home.

METHODS

A cross-sectional design was adopted, using a self-completion questionnaire survey of 253 nursing home staff from 12 nursing homes in Sydney's eastern suburbs, and behavioural assessment of all 647 residents from 11 of the 12 homes. Staff attitudes and strain were measured using the Swedish Strain in Nursing Care Assessment Scale and satisfaction using the Swedish Satisfaction with Nursing Care and Work Assessment Scale.

RESULTS

Staff members' five most prevalent perceptions of residents with dementia were that they are anxious, have little control over their difficult behaviour, are unpredictable, lonely and frightened/vulnerable. The five attributes staff found most difficult to cope with were being aggressive/hostile, having little control over their difficult behaviour, being stubborn/resistive, deliberately difficult, and unpredictable. Although 91% of staff reported that they were happy in their job, a quarter reported that residents provided no job satisfaction. The five satisfaction statements most agreed with were "The patients/residents at work nearly always receive good care", "It is important to try and enter into the way patients experience what happens to them", "Relatives are given enough information about care and treatment", "I enjoy my current work situation" and "Our work organisation is good". There were significant differences between homes in levels of strain related to dementia care that were not accounted for by the level of behavioural disturbance.

CONCLUSIONS

Nursing home staff tended to perceive residents in more negative than positive ways. Staff were generally satisfied with their work. Factors other than resident behavioural disturbance are important influences in nursing staff strain.

Mental health service delivery to older people in New South Wales: perceptions of aged care, adult mental health and mental health services for older people

OBJECTIVE

To compare the perceptions of aged care services, adult mental health services and mental health services for older people regarding aspects of mental health service delivery for older people in New South Wales, Australia.

METHOD

The NSW Branch of the Faculty of Psychiatry of Old Age in association with the NSW Centre for Mental Health, sent a postal survey to all aged care services, adult mental health services and mental health services for older people in NSW. The survey canvassed issues ranging across service profiles, regional variations, availability of resources, processes of care, views on working relationships between services, difficulties and gaps experienced, and ways to improve co-ordination and service delivery. Clinical issues such as the management and practice of psychiatric disorders of old age, educational/training requirements and skill and experience in working with older people were explored.

RESULTS

An overall response rate of 86% was achieved, including 95% from aged care services (n = 58), 74% from adult mental health services (n = 62) and 90% from mental health services for older people (n = 20). Only 59% of aged care services and adult mental health services considered that their local mental health services for older people provided an adequate service; resource and budget limitations were portrayed as the main constraint. Mental health services for older people varied widely in structure, settings and activities undertaken. Access to mental health beds for older people was also variable, and alongside staffing levels was considered problematic. Lack of staff training and/or inexperience in psychogeriatrics posed a challenge for aged care services and adult mental health services.

CONCLUSION

Relationships between aged care services, adult mental health services and mental health services for older people are affected by lack of access to psychogeriatric staff, resource limitations of mental health services for older people, and inadequate liaison and support between the service types. Joint case conferences, education, increased funding of mental health services for older people, and cross referrals were considered ways to address these issues.

Dynamics of the pi(-)p-->pi(0)pi(0)n reaction for p(pi(-))<750 MeV/c

Data are presented for the reaction pi(-)p-->pi(0)pi(0)n in the range from threshold to p(pi(-))=750 MeV/c. The systematics of the data and multipole analyses are examined for sensitivity to a f(0)(600) ("sigma") meson. A one-pion-exchange mechanism is found to be very weak, or absent. The reaction appears to become dominated by sequential pi(0) decays through the Delta(1232) resonance as the beam momentum increases, along with substantial interference effects from several competing mechanisms.

Prediction of mortality in nursing home residents: impact of passive self-harm behaviors

OBJECTIVE

The aim of this study was to determine whether indirect self-destructive behaviors predict mortality in nursing home residents.

METHOD

This cross-sectional study with follow-up after 2 years and 3 months surveyed 593 residents in 10 nursing homes in the eastern suburbs of Sydney, Australia. The following instruments were used: Harmful Behaviors Scale (HBS), Behavioral Pathology in Alzheimer's Disease Rating Scale (BEHAVE-AD), Functional Assessment Staging Scale, Resident Classification Index, Cumulative Illness Rating Scale, Even Briefer Assessment Scales for Depression, and the suicide item from the Structured Hamilton Depression Rating Scale. Diagnoses of depression, dementia, and psychosis were obtained from nursing home records. Mortality data were obtained in August 1999.

RESULTS

At follow-up, 297 (50.1%) residents were still alive with a mean survival time of 565.4 days. Survival analyses found that mortality was predicted by older age, male gender, lower level of functioning, lower levels of behavioral disturbance on the BEHAVE-AD, and higher scores on the HBS "passive self-harm" factor-based subscale, which includes refusal to eat, drink, or take medication.

DISCUSSION

These results suggest that passive self-harm behaviors predict mortality in nursing home residents.

A study of premorbid personality and behavioural and psychological symptoms of dementia in nursing home residents

OBJECTIVE

to investigate the relationship between pre-morbid personality and behavioural and psychological symptoms of dementia (BPSD).

METHODS

we studied 58 subjects with dementia and depression and/or psychosis residing in 11 Sydney nursing homes cross-sectionally. Informal caregivers completed ratings of residents' pre-morbid personality on the NEP Five-Factor Inventory (NEO-FFI). Information on BPSD was obtained using the BEHAVE-AD.

RESULTS

higher neuroticism was predictive of delusions; higher agreeableness of hallucinations, aggressiveness, affective disturbance and overall behavioural disturbance; and higher openness of affective disorder.

CONCLUSION

our findings are inconsistent with previous research and clinical experience. Prospective studies are needed to clarify the association between personality and behavioural disturbance in dementia.

Types of nursing home residents with self-destructive behaviours: analysis of the Harmful Behaviours Scale

OBJECTIVE

To investigate the types of self-destructive behaviours identified by the Harmful Behaviours Scale (HBS) and the variables associated with them.

METHOD

A cross sectional survey involving 647 residents in 11 nursing homes in the eastern suburbs of Sydney, Australia. The following instruments were used: Harmful Behaviours Scale (HBS); Behavioural Pathology in Alzheimer's Disease Rating Scale; Functional Assessment Staging Scale; Resident Classification Index; Health of the Nation Outcome Scale; Even Briefer Assessment Scales for Depression; Abbreviated Mental Test Scale; and the suicide item from the Structured Hamilton Depression Rating Scale. Diagnosis of dementia was obtained from nursing home records.

RESULTS

Latent class analysis of the HBS identified four groups of residents, described as 'aggressive resistant' (34.9%), 'food refusal' (26.8%), 'behaviourally disturbed' (5.4%) and a 'non-symptomatic' group (33.0%) with little self-destructive behaviour. The behaviourally disturbed group engages in a widespread combination of direct and indirect self-destructive behaviours and displays other behavioural and psychological symptoms of dementia. In contrast, the food refusal group whose only behavioural symptom was refusal to eat and drink had the most cognitive impairment and did not show higher levels depression or suicidal ideation.

CONCLUSIONS

We have found three groups of residents with self-destructive behaviours and each group is associated with a different pattern of variables.

Self-destructive behaviors in nursing home residents

OBJECTIVES

To validate the Harmful Behaviors Scale (HBS) as a measure of direct and indirect self-destructive behaviors in nursing home residents and to determine the prevalence of self-destructive behaviors and their relationship to other variables.

DESIGN

A cross-sectional study.

SETTING

Eleven nursing homes in the eastern suburbs of Sydney, Australia.

PARTICIPANTS

Six hundred ten nursing home residents aged 65 and older.

MEASUREMENTS

Instruments used were the HBS, Behavioral Pathology in Alzheimer's Disease Rating Scale (BEHAVE-AD), Functional Assessment Staging Scale (FAST), Even Briefer Assessment Scale for Depression (EBAS-Dep), and the suicide item from the structured Hamilton Depression Rating Scale. Data on diagnoses of dementia, depression, or psychotic disorder; prescription of psychotropic medication; and demographics were obtained from nursing home records.

RESULTS

On the HBS, indirect harmful behaviors occurred at least weekly in 61% of subjects, and direct harmful behaviors occurred in 14% of subjects. The HBS total score was significantly positively correlated with the BEHAVE-AD score (Pearson's r=0.679, P <.001) but not with the EBAS-Dep "wish for death" item and total score. HBS scores were significantly higher in residents scoring greater than zero on the Hamilton suicide item (F=1.380, df=3,325, P=.249). Stepwise multiple linear regression indicated that younger age, chart diagnosis of dementia, greater incapacity as measured by FAST, and a higher Hamilton suicide item score predicted a higher HBS total score.

CONCLUSIONS

Self-destructive behaviors are common in nursing home residents and are mostly related to dementia. There was little evidence of a relationship between depression and self-destructive behaviors.

Psychosis, depression and behavioural disturbances in Sydney nursing home residents: prevalence and predictors

BACKGROUND

There is wide variation in the rates of behavioural and psychological symptoms of dementia (BPSD) reported in nursing homes.

AIMS

This study aimed to investigate: (1) the prevalence of BPSD in nursing home residents using the BEHAVE-AD; (2) the relationships of BPSD with (a) demographic, (b) dementia, (c) diurnal and (d) nursing home variables; and (3) the inter-relationships between different types of BPSD, as measured by subscales of the BEHAVE-AD.

RESULTS

Over 90% of residents exhibited at least one behavioural disturbance. Specifically, there was evidence of psychosis in 60%, depressed mood in 42% and activity disturbances or aggression in 82% of residents. Younger, more functionally impaired residents with a chart diagnosis of psychosis had higher BPSD rates, as did those residing in larger nursing homes. Individual BPSD were significantly intercorrelated.

CONCLUSIONS

BPSD are ubiquitous in nursing home residents. Behavioural disturbances are frequently associated with psychosis and/or depression. The findings suggest the need for psychogeriatric services to nursing homes and smaller facilities.

Use of psychotropics in Sydney nursing homes: associations with depression, psychosis, and behavioral disturbances

The purpose of this study was to determine the prevalence of psychotropic use in nursing home residents, the extent to which psychotropic dosage is consistent with published guidelines, and the relationships between psychotropic class and psychiatric and behavioral disturbances. Six hundred forty-seven subjects, mean age 82.3 years, residing in 11 nursing homes in the eastern suburbs of Sydney, Australia, were assessed using the Behavioral Pathology in Alzheimer's Disease Rating Scale (BEHAVE-AD), the Abbreviated Mental Test Scale, and the Even Briefer Assessment Scale for Depression (EBAS-DEP). Details of psychotropic prescription and diagnoses of depression, dementia, and psychosis were obtained from nursing home charts. Psychotropics were prescribed for 333 (51.5%) residents, 381 (58.9%) if "as required" (PRN) use is included. Prescription of multiple psychotropics was present in 148 (22.7%) residents. Antidepressants were prescribed for 19.8% of residents, with subtherapeutic doses less likely in residents on selective serotonin reuptake inhibitors. On logistic regression, the use of antidepressants was predicted by the affective disturbances subscale on the BEHAVE-AD. Only 30.4% of residents with significant depressive symptoms on the EBAS-DEP were prescribed antidepressants. Antipsychotics were prescribed for 21.3% residents at a mean dosage of 73 mg chlorpromazine equivalence. Residents on antipsychotics had significantly higher scores on the delusions, hallucinations, activity disturbance, and aggressiveness subscales of the BEHAVE-AD. On logistic regression, only the activity disturbance subscale and chart diagnoses of dementia and psychosis were significant predictors. Psychosis (58.8%) and behavioral disturbances (91.9%) were more prevalent in residents prescribed antipsychotics than in residents not prescribed antipsychotics (42.5% and 76.6%, respectively). High rates of behavioral and psychological symptoms of dementia remained in residents prescribed antipsychotics and high rates of depressive symptoms in residents prescribed antidepressants, suggesting a role for nonpharmacological strategies.

Case-controlled study of nursing home residents referred for treatment of vocally disruptive behavior

The aim of this study was to identify factors associated with vocally disruptive behavior (VDB) in nursing home patients referred to aged care services for treatment, using a case-control methodology. Characteristics of the VDB, reasons for referral, perceived causal factors, and psychotropic use were noted. Twenty-five subjects and controls were examined with the Screaming Behavior Mapping Instrument, the Cornell Scale for Depression in Dementia, the Dementia Behavior Disturbance Scale, and measures of cognition, functional capacity, social activities, and emotional reactions of nursing staff. VDB was associated with other disturbed behaviors, depression, anxiety, severe dementia, functional impairment, communication difficulties, use of psychotropic medication, social isolation, and emotional distress in the nursing staff. Reasons for referral may relate more to the stress experienced by nursing home staff in managing VDB than to specific attributes of the VDB itself.

The effectiveness of old age psychiatry services

The objective of this study was to review outcomes of acute service delivery in old age psychiatry. Sources of data included Medline, PsycINFO and Cochrane Collaboration databases of English language papers to 1998 on service delivery evaluation in 'old age psychiatry', 'psychogeriatrics' and 'geriatric psychiatry', supplemented by a manual search of references from relevant literature. All controlled trials, audits, and surveys of the outcomes of service delivery in old age psychiatry located in acute hospitals and community settings were included. Service delivery by medical, adult psychiatry and consultation/liaison services were included. With the exception of outreach services to nursing homes, long term institutional care was excluded. All data were extracted by the author. Data quality was assessed by applying an evidence hierarchy. Evaluation strategies were qualitatively reviewed. Controlled trials, audits and surveys were each found to provide important data in the evaluation of service delivery. There is better quality evidence to support the effectiveness of components of old age psychiatry services than other service types. The majority of studies indicate that old age psychiatry services have positive acute treatment outcomes, particularly with depression. There is insufficient evidence to determine which processes of care are associated with better outcomes. Pluralistic evaluations indicate that carers often have unmet needs and are not as positive about outcomes. There have been no controlled comparisons of service delivery provided by other services. In conclusion, controlled trials and audits indicate that old age psychiatry services are effective. Further pluralistic evaluations and comparisons with other services are required.
