Depressive disorders among elderly people in long-term institutional care

Instituting Sustainable Geriatric Care in Africa: The Roles of Sociocultural Constructs

The demographic shift in Africa is seeing more people make it to old age (60 years or over), a state associated with an increased risk of acquiring communicable and non-communicable diseases, and demand for specialised health care. With many African health systems still struggling with infectious diseases, inadequate funding, poor infrastructure and lack of skilled human resource for health, how best can they provide quality, sustainable geriatric care services to their ageing population? This commentary highlights “Africa's social-cultural structure” as an opportunity health policy makers could tap into, to design patient-centred, sustainable, inexpensive, and socially acceptable geriatric interventions.

Association of depression with malnutrition, grip strength and impaired cognitive function among senior trauma patients

BACKGROUND

Depression is common among senior adults, yet understudied among trauma patients. The purpose of this study was to assess the prevalence of depressive symptoms among seniors hospitalized in acute trauma care, to compare patients with depressive symptoms vs. those without, and to evaluate whether depression symptoms affects discharge destination.

METHODS

This cross-sectional and prospective analysis was conducted among community-dwelling patients ≥70 years old, hospitalized at the Senior Trauma Center of the University Hospital Zurich, Switzerland. We used the Geriatric Depression Scale (GDS-15) to assess presence of depressive symptoms. Using a cutoff value of 5 points, we compared age- and gender-adjusted characteristics of patients with and without depressive symptoms. Multinomial logistic regression models were used to estimate the odds of returning home vs. not adjusting for age, gender, nutritional status, cognitive function and others.

RESULTS

Of the 273 seniors enrolled, 104 (38.1%) were men and the mean age was 79.4 (SD = 6.5) years. We identified 52 (19.0%) patients with depressive symptoms. These patients were more likely to be older (p = 0.04), at risk for malnutrition (p<0.0001), at least pre-frail (p = 0.005), and have decreased cognitive function (p = 0.001). They were also more than twice as likely to be discharged to acute geriatric care compared to home (OR = 2.28 (CI = 1.12-4.68)).

LIMITATIONS

Depressive symptoms were assessed during acute care without data before hospitalization.

CONCLUSIONS

Senior trauma patients with depressive symptoms during acute care were more likely to be at higher risk of malnutrition, have cognitive decline and are more likely to receive additional geriatric care.

Validity of the geriatric depression scale and the collateral source version of the geriatric depression scale in nursing homes

BACKGROUND

Depression is a common psychiatric disorder in older people. The study aimed to examine the screening accuracy of the Geriatric Depression Scale (GDS) and the Collateral Source version of the Geriatric Depression Scale (CS-GDS) in the nursing home setting.

METHODS

Eighty-eight residents from 14 nursing homes were assessed for depression using the GDS and the CS-GDS, and validated against clinician diagnosed depression using the Semi-structured Clinical Diagnostic Interview for DSM-IV-TR Axis I Disorders (SCID) for residents without dementia and the Provisional Diagnostic Criteria for Depression in Alzheimer Disease (PDCdAD) for those with dementia. The screening performances of five versions of the GDS (30-, 15-, 10-, 8-, and 4-item) and two versions of the CS-GDS (30- and 15-item) were analyzed using receiver operating characteristic (ROC) curves.

RESULTS

Among residents without dementia, both the self-rated (AUC = 0.75-0.79) and proxy-rated (AUC = 0.67) GDS variations performed significantly better than chance in screening for depression. However, neither instrument adequately identified depression among residents with dementia (AUC between 0.57 and 0.70). Among the GDS variations, the 4- and 8-item scales had the highest AUC and the optimal cut-offs were >0 and >3, respectively.

CONCLUSIONS

The validity of the GDS in detecting depression requires a certain level of cognitive functioning. While the CS-GDS is designed to remedy this issue by using an informant, it did not have adequate validity in detecting depression among residents with dementia. Further research is needed on informant selection and other factors that can potentially influence the validity of proxy-based measures in the nursing home setting.

The clinical utility of the Cornell Scale for Depression in Dementia as a routine assessment in nursing homes

OBJECTIVE

To examine the clinical utility of the Cornell Scale for Depression in Dementia (CSDD) in nursing homes.

SETTING

14 nursing homes in Sydney and Brisbane, Australia.

PARTICIPANTS

92 residents with a mean age of 85 years.

MEASUREMENTS

Consenting residents were assessed by care staff for depression using the CSDD as part of their routine assessment. Specialist clinicians conducted assessment of depression using the Semi-structured Clinical Diagnostic Interview for DSM-IV-TR Axis I Disorders for residents without dementia or the Provisional Diagnostic Criteria for Depression in Alzheimer Disease for residents with dementia to establish expert clinical diagnoses of depression. The diagnostic performance of the staff completed CSDD was analyzed against expert diagnosis using receiver operating characteristic (ROC) curves.

RESULTS

The CSDD showed low diagnostic accuracy, with areas under the ROC curve being 0.69, 0.68 and 0.70 for the total sample, residents with dementia and residents without dementia, respectively. At the standard CSDD cutoff score, the sensitivity and specificity were 71% and 59% for the total sample, 69% and 57% for residents with dementia, and 75% and 61% for residents without dementia. The Youden index (for optimizing cut-points) suggested different depression cutoff scores for residents with and without dementia.

CONCLUSION

When administered by nursing home staff the clinical utility of the CSDD is highly questionable in identifying depression. The complexity of the scale, the time required for collecting relevant information, and staff skills and knowledge of assessing depression in older people must be considered when using the CSDD in nursing homes.

Psychiatric consultation to elderly medical inpatients in a general hospital

Objectives: To determine the reasons for referral of elderly medical inpatients for psychiatric consultation and the appropriateness of such referrals. To determine whether the provision of a consultation service is associated with increases in referral rates over time.

Method: One hundred consecutive referrals seen over an 18-week period were included in the study and data on reason for referral, ICD-10 diagnosis and recommended interventions gathered prospectively. Rates of referral were calculated and compared with a similar study performed in the same location five years previously.

Results: In this location the most frequent reason for referral was for assessment of depressive symptoms (47%). Referrals were generally appropriate and there was a high degree of concordance between reason for referral and psychiatric diagnosis, particularly for depressive symptoms. There was a moderate (22%) increase in referral rates in the five years since the previous study. Concordance rates between reason for referral and psychiatric diagnosis had improved considerably during this period, particularly for depressive symptoms.

Conclusions: Referral rates for psychogeriatric consultation increase over time. Referrals are generally appropriate, and recognition of depressive illness improves. Psychiatric illness may still be under-recognised and increasing workload may indicate a need for more refined models of service delivery.

Évaluation de l’usage à risque des benzodiazépines chez les personnes âgées : facteurs de risque et impacts

L’usage à risque de la benzodiazépine (BZD), fréquent chez les aînés, est un problème souvent sous-estimé. Cet article présente une recension des écrits qui explore ce profil de consommation problématique sur les plans biologique, psychologique et environnemental. Les auteurs constatent qu’il y un manque de consensus et de validité quant à la description du phénomène. Ils discutent de certains facteurs qui contribuent à l’usage à risque des BZD chez les aînés : des habitudes de prescriptions et des attitudes parfois laxistes des médecins ; les attitudes des aînés envers la maladie mentale et la façon dont se manifestent leurs symptômes ; les difficultés dans l’évaluation de l’anxiété et de la dépression des aînés. En conclusion, les auteurs proposent que la recherche s’intéresse à des méthodes intégratives pour l’évaluation de l’usage à risque de la BZD chez les aînés.

Depression in older people living in residential homes

There is a large body of published research relating to depression in residential homes for older people (also called long-term-care homes, and including both nursing homes and hostels) (Ames 1990; 1993; Seitzet al., 2010; Snowdon and Purandare, 2010; Snowdon, 2010). However, despite increased detection and more frequent treatment in recent years, depression remains a significant problem for many older people living in such settings. This guest editorial summarizes current knowledge about prevalence, etiology, detection and screening, treatment and outcomes of depression in residential homes and concludes with a summary of key issues requiring urgent future action.

Effect of essential amino acid supplementation on quality of life, amino acid profile and strength in institutionalized elderly patients

BACKGROUND & AIMS

This study assessed the efficacy of supplemented essential amino acids on depressive symptoms, nutrition, muscle function, daily physical activity, and health-related quality of life (HRQoL) of institutionalized elderly patients.

METHODS

Forty-one patients (58.5% women; mean age 79.8 yrs) with sequelae of coronary artery disease (73%), femoral fracture (34%), were randomly assigned to receive oral essential amino acids 4 gr 2 times a day for 8 weeks or isocaloric placebo. Before randomization and 8 weeks after the protocol started, the following variables were measured: depressive symptoms (Geriatric Depression Scale, GDS), nutritional panel (Mini Nutritional Assessment, MNA; serum albumin and prealbumin levels), muscle strength (Hand Grip, HG), Activity Daily Life (ADL), Quality of Life (SF-36, HRQoL) and amino acid profile.

RESULTS

Compared with the placebo group, EAA patients improved nutrition (MNA score 22.6 ± 1.5 post vs 21.8 ± 1.6 pre; p < 0. 04, albumin g/dl 4.04 ± 0.35 post vs 3.88 ± 0.3 pre; p < 0.01), GDS(score 10.3 ± 1.75 post vs 13.85 ± 3.37 pre; p < 0.001), HG (Kg 19.75 ± 1.7 post vs 18.68 ± 1.36 pre; p = 0.001), ADL (p < 0.04) and both physical and mental components of SF-36 (p < 0.002).

CONCLUSIONS

Oral supplementation with essential amino acids improved several determinants of quality of life in institutionalized elderly patients, including depressive symptoms, nutrition, muscle function and daily life activity.

Ability of nurses to identify depression in primary care, secondary care and nursing homes--a meta-analysis of routine clinical accuracy

PURPOSE

To clarify the ability of nurses and nursing assistants working in primary care, secondary care and nursing homes to identify depressed individuals using their clinical skills using meta-analysis of published studies.

METHODS

Literature search, appraisal and meta-analysis. We located 22 studies reporting on the detection of depression, 4 involving primary care or community nurses; 7 involving hospital nurses and 11 from nursing homes.17 of 22 studies had specificity data.

RESULTS

Across all 22 studies involving 7061 individuals, and a prevalence of 28.1% (95% CI=22.6-33.9%), practice and community nurses correctly identified 26.3% (95% CI=16.2-37.8%) of people with depression. They also correctly identified 94.8% (95% CI=91.3-97.4%) of the non-depressed. Nurses working in hospital settings correctly identified 43.1% (95% CI=31.9-54.8%) of people with depression and 79.6% (95% CI=71.5-86.7%) of the non-depressed. Those working in nursing homes correctly identified 45.8% (95% CI=38.1-53.6%) of people with depression and 80.0% (95% CI=68.6-88.7%) of the non-depressed.

CONCLUSIONS

Nurses have considerable difficulty accurately identifying depression but are probably at least as accurate as medical staff.

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.

Factors associated with depression in Norwegian nursing homes

BACKGROUND

Depression among patients in nursing homes is frequent and apparently underdiagnosed. Because depression is associated with negative outcomes, identification of groups at risk would improve the diagnosis and potentially improve the prognosis.

AIM

To confirm or reject the hypothesis that depression in nursing homes is associated with worse medical health, cognitive and functional impairment.

METHODS

A sample of 902 randomly selected nursing-home patients was assessed using the Cornell Scale, the Clinical Dementia Rating Scale (CDR) the Self-Maintenance Scale and a general measurement of medical health. Additionally, information was collected from the patients' records. A multiple linear regression was performed with the Cornell Scale total score, and mood and non-mood subscale scores as the dependent variables.

RESULTS

In the adjusted analysis, depression according to the Cornell total score was associated with worse medical health (strongest) and worse cognitive impairment (p < 0.001), but not with worse functional impairment. The mood subscale score was associated with worse medical health (strongest, p = 0.001), pulmonary diseases (p = 0.007), being unmarried (p = 0.019) and female gender (p = 0.022), but not with worse cognitive impairment. The non-mood subscale score was correlated with cognitive impairment (strongest, p < 0.001), worse medical health (p < 0.001), younger age (p = 0.001), digestive diseases (p = 0.033) and not having suffered from stroke (p = 0.045).

CONCLUSION

Our hypothesis was partially confirmed. Worse general medical health was the strongest factor associated with depression, followed by degree of cognitive impairment. Cognitive impairment was not associated with the mood subscale score, but was the strongest correlate for the non-mood symptoms of the Cornell Scale.

Recognising depression in residential facilities: an Australian challenge

BACKGROUND

Depression in aged care facilities (ACFs) is reportedly under-recognised and under-treated. Observer-rated and self-rated depression rating scales can help identify cases of depression, and could be used to estimate the prevalence of depression in ACFs.

METHOD

Direct care staff in 168 ACFs used a survey form and administered the Cornell Scale for Depression in Dementia (CSDD) and (in those able to be tested) the 15-item Geriatric Depression Scale (GDS-15) to every fourth resident. In seven facilities the same subjects were clinically assessed and (where appropriate) diagnosed by a psychiatrist.

RESULTS

Survey forms and CSDD ratings were completed by staff concerning 91.6% of the one-in-four selected subjects. Their mean age was 82.1 years. CSDD scores of 8 or more, indicating depression, were recorded for 34.7% of the ACF residents, comprising 40.5% of the 1,084 high care (nursing home level) residents, and 25.4% of the 674 low care residents. Of 1,250 residents tested with the GDS-15, 41.1% scored 6 or more, indicating depression. The correlation between GDS-15 and CSDD scores was 0.6. Use of the survey tool allowed staff to identify which factors were most strongly associated with depression, the strongest being grief over loss of abilities and opportunities to participate in valued activities.

CONCLUSIONS

The CSDD (and the GDS-15 in those without severe cognitive impairment) proved useful in identifying residents who were depressed. Survey questions helped draw attention to factors of importance in development or persistence of these depressions, and hence to strategies for intervention.

Prevalence and risk factors for depression in a longitudinal, population-based study including individuals in the community and residential care

OBJECTIVE

The authors report the population prevalence of depression in older adults living in the community and in residential care. Demographic, medical, health behavior, functional and cognitive measures, and transition to residential care are evaluated as risk factors for depression over eight years.

METHODS

Depression prevalence estimates were obtained from the initial electoral role sample of the Australian Longitudinal Study of Ageing that included persons living in residential care. A subsample (N = 1,116) based on follow-up data were included in longitudinal multilevel analyses that evaluated between-person and within-person predictors associated with scores from the Center for Epidemiology-Depression Scale.

RESULTS

At wave 1, 14.4% of community-dwelling and 32.0% of residential care-dwelling participants were depressed (15.2% of total cases). Increase in depression was associated with antidepressant status, sex, education, and marital status, but not history of hypertension, stroke, diabetes, heart disease, or smoking. Time-varying predictors, including residential care, activities of daily living, instrumental activities of daily living, self-rated health, and Mini-Mental State Examination, predicted depressive symptoms both between and within persons.

CONCLUSIONS

Depression is strongly linked with factors indicating increased dependency. Risk assessment and targeting of intervention strategies to prevent depression in late life should incorporate changes in functional capacity, mental status, and need for residential care.

The effects of reminiscence on psychological well-being in older adults: a meta-analysis

This paper presents the results of a meta-analysis to assess the effectiveness of reminiscence on psychological well-being across different target groups and treatment modalities. Fifteen controlled outcome studies were included. An overall effect size of 0.54 was found, indicating a moderate influence of reminiscence on life-satisfaction and emotional well-being in older adults. Life-review was found to have significantly greater effect on psychological well-being than simple reminiscence. In addition, reminiscence had significantly greater effect on community-dwelling adults than adults living in nursing homes or residential care. Other characteristics of participants or interventions were not found to moderate effects. It is concluded that reminiscence in general, but especially life review, are potentially effective methods for the enhancement of psychological well-being in older adults. However, a replication of effectiveness studies of the well-defined protocols is now warranted.

Do older Australians truly have low rates of anxiety and depression? A critique of the 1997 National Survey of Mental Health and Wellbeing

This paper sets out to critically evaluate reports from the Australian-wide National Survey of Mental Health and Wellbeing of very low rates of ICD-10 anxiety and depressive disorders in community resident older Australians. Data from the National Survey, which relied on the Composite International Diagnostic Interview (CIDI) were re-computed and re-analysed to address concerns about population sampling, interview response patterns and alternate measures of mental health. Rates of anxiety and depressive disorders fell to low levels after 65 years and continued to fall thereafter. This is at odds with findings from gerontological surveys that used assessment tools better suited to frail older people. Scores on mental health scales, together with diagnostic algorithms that obviated CIDI skip patterns, showed much less change in mental wellbeing across generations. It is argued that sampling and case ascertainment bias combined to reduce rates of anxiety and depression in very old people, especially when adjustments are made for the high morbidity levels encountered in aged residential facilities. Functional mental disorders almost certainly rise in frequency in advanced old age, often in conjunction with dementia.

Analysis of a care planning intervention for reducing depression in older people in residential care

Approximately 40% of older people in residential care have significant symptoms of depression. A training and care-planning approach to reducing depression was implemented for 114 depressed residents living in 14 residential care homes in North Yorkshire, UK. Care staff were offered brief mental health training by community mental health teams for older people. They were then assigned to work individually with residents in implementing the care-planning intervention, which was aimed at alleviating depression and any health, social or emotional factors that might contribute to the resident's depression. Clinically significant improvements in depression scores were associated with implementation of the care-planning intervention as evidenced by changes in scores on the Geriatric Mental State Schedule-Depression Scale. There was evidence of an interaction between the power of the intervention and degree of dementia. These improvements were not accounted for by any changes in psychotropic medication. The training was highly valued by care staff and heads of homes, and they considered that the care-planning intervention represented an improvement in quality of care for all residents, irrespective of levels of dementia. Staff also reported improvements in morale and increased confidence in the caring role as a result of their participation. The limitations of this study are discussed. On the basis of a growing body of evidence, it is argued that there is an urgent need for a suitably powered randomised controlled trial and economic evaluation, to test the cost-effectiveness of personalised care planning interventions aimed at reducing depression in older people in residential care.

Prevalence and predictors of depression in populations of elderly: a review

OBJECTIVE

To offer an update on prevalence and predictors of old age depression in populations of elderly Caucasians.

METHOD

The databases MEDLINE and Psychinfo were searched and relevant literature from 1993 onwards was reviewed.

RESULTS

The prevalence of major depression ranges from 0.9% to 9.4% in private households, from 14% to 42% in institutional living, and from 1% to 16% among elderly living in private households or in institutions; and clinically relevant depressive symptom 'cases' in similar settings vary between 7.2% and 49%. The main predictors of depressive disorders and depressive symptom cases are: female gender, somatic illness, cognitive impairment, functional impairment, lack or loss of close social contacts, and a history of depression.

CONCLUSION

Depression is frequent in populations of elderly. Methodological differences between the studies hinder consistent conclusions about geographical and cross-cultural variations in prevalence and predictors of depression. Improved comparability will provide a basis for consistent conclusions.

Symptoms of psychological distress among older adults in Canadian long-term care centres

Psychological distress can lead to negative consequences affecting the quality of life of older adults living in long-term care centres. The goal of this study was to determine the prevalence of symptoms of psychological distress and their associated factors among these residents. A cross-sectional descriptive study was conducted among 1999 long-term care residents aged 65 and over. Nine hundred and eleven persons (45.6%) displayed at least one symptom of psychological distress either at one time or more in the week preceding data collection, and 22.4% were identified as psychologically distressed. Multivariate analysis indicated that psychological distress was associated with disruptive behaviours and benzodiazepine use among women residents, and with insomnia in men residents. In conclusion, when clinicians screen for mental health disorders, they should take into consideration that symptoms of insomnia or disruptive behaviours may mask psychological distress.

Care staff training in detection of depression in residential homes for the elderly: randomised trial

BACKGROUND

Many people with depression in residential care homes for the elderly do not receive treatment because their depression remains undetected.

AIMS

To determine the effects of staff training on the detection, treatment and outcome of depression in residents of ten homes.

METHOD

We conducted a randomised controlled trial in ten residential homes. The intervention consisted of a training programme for staff and collaborative evaluation by staff and a mental health specialist of residents with possible depression.

RESULTS

Recognition of depression increased more in homes where staff received the training than in the control homes. Treatment rates also increased compared with control homes, but the increase was not significant. Residents with depressive symptoms had a more favourable course when staff had received training. Moreover, the prevalence of depressive symptoms decreased, but the decrease was not significant.

CONCLUSIONS

Training of care staff results in the increased detection of depression in the elderly, a trend towards more treatment and better outcomes.

Screening for depression in patients in long-term care facilities: a randomized controlled trial of physician response

OBJECTIVES

To determine the effect of a screening protocol using the Geriatric Depression Scale (GDS) on the frequency of primary care physicians' decisions to prescribe drug therapy or refer long-term care patients with possible depression to mental health care.

DESIGN

Case-finding phase, followed by a randomized controlled trial of the effect of a physician-targeted intervention on antidepressant prescribing or referral to mental health services.

SETTING

Twenty-two nonacademic long-term care facilities.

PARTICIPANTS

One hundred three of 1,602 patients aged 65 and older who met criteria for cognitive function and untreated symptoms of depression.

INTERVENTION

The 77 physicians of these patients were randomized as clusters into an early notification (experimental) or a delayed notification (control) group.

MEASUREMENTS

Frequency of physician response (mental health consult or antidepressant therapy) at 4 and 8 weeks from notification, physician follow-up, and factors associated with physician response.

RESULTS

Frequency of physician response in the early group (25%) was greater than in the delayed group (2%) (P <.005) 4 weeks from baseline. Physician response rate when the groups were combined was 36% (95% confidence interval (CI) = 26%-46%) 8 weeks from notification. Overall, there was evidence of physician action after letters of notification in 69% (95% CI = 60%-78%) of cases. Univariate logistic regression suggested that physicians' decisions were primarily associated with physician-related characteristics.

CONCLUSIONS

Screening of long-term care patients for depression can increase the frequency of treatment or referral by primary care physicians.

Ego-integrity versus ego-despair: the effect of "accepting the past" on depression in older women

The relative strength of the later-life personality process of ego-integrity, as operationalized by "accepting the past," was tested as a predictor of depression in a multivariate model containing other well established predictors-age, social support, physical dependency, and positive and negative affectivity. Seventy-three older Australian women living in supported accommodation completed an anonymous, self-report questionnaire. The results showed that "accepting the past" was a significant predictor in the multivariate model, along with social support, physical dependency, and positive affectivity. The results are discussed in terms of the utility of investigating later-life personality processes as potential interventions for alleviating depression in older people.

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.

Long-term benzodiazepine use by elderly people living in the community

OBJECTIVE

To investigate the prevalence of long-term benzodiazepine use in an elderly community sample, and factors associated with such use.

METHOD

Data came from the Sydney Older Persons Study, a longitudinal study of people aged 75 or over. There were 337 subjects who were interviewed in 1991-93, and subsequently followed up after three and 4.5 years. At the first interview, subjects were assessed for socio-demographic characteristics, physical and mental health, and use of health services. At the first and subsequent interviews, subjects were asked about use of medications, including benzodiazepines.

RESULTS

There were 16.6% who were using benzodiazepines at the time of all three interviews, while a further 19.6% were using them at one or two interviews. In a multivariate ordered logit regression model, long-term benzodiazepine use was associated with treatment for nervous conditions, restless sleep, being female, being divorced and greater contact with medical services.

CONCLUSIONS

The prevalence of benzodiazepine use in the elderly is high and much of this use is long term. The high prevalence of benzodiazepine use stands in contrast to the findings from national surveys that the elderly living in the community tend to have better mental health than younger age groups.

IMPLICATIONS

Efforts are needed to reduce the number of elderly people becoming long-term users. The use of benzodiazepines in this age group is of particular concern, because they may be a risk factor for falls and for cognitive impairment in the elderly.

Multifaceted shared care intervention for late life depression in residential care: randomised controlled trial

OBJECTIVE

To evaluate the effectiveness of a population based, multifaceted shared care intervention for late life depression in residential care.

DESIGN

Randomised controlled trial, with control and intervention groups studied one after the other and blind follow up after 9.5 months.

SETTING

Population of residential facility in Sydney living in self care units and hostels.

PARTICIPANTS

220 depressed residents aged >/=65 without severe cognitive impairment.

INTERVENTION

The shared care intervention included: (a) multidisciplinary consultation and collaboration, (b) training of general practitioners and carers in detection and management of depression, and (c) depression related health education and activity programmes for residents. The control group received routine care.

MAIN OUTCOME MEASURE

Geriatric depression scale.

RESULTS

Intention to treat analysis was used. There was significantly more movement to "less depressed" levels of depression at follow up in the intervention than control group (Mantel-Haenszel stratification test, P=0.0125). Multiple linear regression analysis found a significant intervention effect after controlling for possible confounders, with the intervention group showing an average improvement of 1.87 points on the geriatric depression scale compared with the control group (95% confidence interval 0.76 to 2.97, P=0.0011).

CONCLUSIONS

The outcome of depression among elderly people in residential care can be improved by multidisciplinary collaboration, by enhancing the clinical skills of general practitioners and care staff, and by providing depression related health education and activity programmes for residents.

Life review: preventing despair in newly relocated nursing home residents short- and long-term effects

Relocation to a nursing home places frail elders at risk for developing depression and suicide ideation. This study followed two hundred and fifty-six newly relocated nursing home residents for five years. Using a Solomon Four research design, participants were divided into four groups, two control and two experimental, one each with pretesting and all with posttesting. Participants in the control groups received a friendly visit and those in the experimental groups received the intervention of life review. Immediate short-term results showed the life review to be an effective preventive intervention for clinical depression (p = .05). Additionally, when looking at long-term effects at one year, there were significant decrease in depression (p = .05), hopelessness (p = .01), and psychological well-being (p = .02) with measurable increases in life satisfaction (p = .08). These findings support the hypothesis that life review prevents despair in frail elders newly admitted to a nursing home.
