The prevalence and recognition of major depression among low-level aged care residents with and without cognitive impairment

Previous research has demonstrated a high level of depression in nursing homes. The current study was designed to determine the prevalence of depression, using a structured diagnostic interview, among older people with and without mild-moderate cognitive impairment residing in low-level care facilities. The results demonstrated that, consistent with previous research in nursing homes, 16.9% of older people were diagnosed with major depressive disorder. Less than half of these cases had been detected or treated. Individuals with moderate cognitive impairment were more likely to be depressed, but cognitive impairment did not appear to act as a strong impediment to the detection of depression by general practitioners. A low awareness of their use of antidepressant medications was demonstrated among older people prescribed this treatment, including those with normal cognitive function. Reasons for the poor recognition of depression among older people are discussed.

Malnutrition prevalence in aged care residents: A pilot study

Malnutrition is a significant clinical and public health problem. The prevalence of malnutrition was determined in a sample of older people living in 2 residential aged care facilities in Australia. The Subjective Global Assessment tool was used to determine the prevalence of malnutrition in 57 residents. The majority of residents were well nourished (67), 26 moderately malnourished, and 7 severely malnourished. Prevalence of malnutrition was higher for those receiving high-level care (42), but this was not statistically significant (P =.437). No relationship was found between malnutrition status and age (P =.529) or sex (P =.839).

Treatment of depression in low-level residential care facilities for the elderly

Background: The rate of recognition and treatment of depressed older people in nursing homes is low. Data from the low-level residential care population have not been reported. This study aimed to collect information about the treatment of depression among older persons living in low-level residential care (hostels).

Method: The participants comprised 300 elderly residents from ten low-level residential care facilities from various suburbs in metropolitan Melbourne. The participants were interviewed by a trained clinical psychologist to determine the presence or absence of major or minor depressive disorder using the Structured Clinical Interview for DSM-IV Axis I Disorder (SCID-I). Each participant was also administered the Standardized Mini-mental State Examination (SMMSE) to determine level of cognitive function. The clinical psychologist then reviewed all cases in consultation with a geropsychiatrist experienced in the diagnosis of depression among older people, prior to assigning a diagnosis of depression.

Results: An important finding in this study was the low treatment for currently depressed residents, with less than half of those in the sample who were depressed receiving treatment. However, 61 of the 96 residents out of the sample of 300 who were on antidepressants were not currently depressed.

Conclusion: There is an under recognition and under treatment of currently depressed older people in low-level residential care facilities (hostels) just as has been reported in studies in nursing homes. However, there are high numbers receiving antidepressants who are not currently depressed.

Professional carers' knowledge and response to depression among their aged-care clients : the care recipients' perspective

Depression is an under-diagnosed disorder among the elderly, even in those who are in receipt of aged-care services. One factor associated with this under diagnosis has been identified as a reluctance amongst the elderly to discuss their mood and emotions with their medical practitioners. The current study focused on why depression is not recognised and acted on by those providing residential or home-based care to older people. We interviewed 15 elderly people residing in high-level or low-level aged-care facilities, and three elderly people who were receiving personal care in their homes. All participants had been identified by their care agencies as depressed. Participants reported their perceptions of their personal carers' knowledge and practices in managing the residents' depression. Although the participants described their carers in positive terms, they were critical of their knowledge and skills in recognising depression, and indicated that the communication between personal carers and care recipients about depressive symptomatology was seriously flawed. Training for personal carers in these areas, and efforts to change organisational culture are recommended.

An examination of the 'gold standard' diagnosis of major depression in aged-care settings

Objectives: Individual clinical interviews are typically viewed as the “gold standard” when diagnosing major depressive disorder (MDD) and when examining the validity of self-rated questionnaires. However, this approach may be problematic with older people, who are known to underreport depressive symptomatology. This study examined the effect of including an informant interview on prevalence estimations of MDD in an aged-care sample.

Design: The results of an individual clinical interview for MDD were compared with those obtained when an informant interview was incorporated into the assessment. Results from each diagnostic approach were compared with scores on a self-rated depression instrument.

Setting: Low-level aged-care residential facilities in Melbourne (equivalent to “residential homes,” “homes for the elderly,” or “assisted living facilities” in other countries).

Participants: One hundred and sixty-eight aged-care residents (mean age: 84.68 years; SD: 6.16 years) with normal cognitive functioning.

Measurements: Individual clinical interviews were conducted using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition Axis I Disorders. This interview was modified for use with staff informants. Self-reported depression was measured using the Geriatric Depression Scale-15 (GDS-15).

Results: The estimated point prevalence of MDD rose from 16% to 22% by including an informant clinical interview in the diagnostic procedure. Overall, 27% of depressed residents failed to disclose symptoms in the clinical interview. The concordance of the GDS-15 with a diagnosis of MDD was substantially lower when an informant source was included in the diagnostic procedure.

Conclusion: Individual interviews and self-report questionnaires may be insufficient to detect depression among older adults. This study supports the use of an informant interview as an adjunct when diagnosing MDD among cognitively intact aged-care residents.

Maintaining nutrition in aged care residents with a train-the-trainer intervention and nutrition coordinator

Objective: To investigate the impact of a train-the-trainer program on the nutritional status of older people in residential care. ----- Design: Prospective, randomized controlled study. Setting: Eight nursing homes in Southeast Queensland, Australia. ----- Participants: A total of 352 residents participated - 245 were female (69.6%). The mean age was 84.2 years and the majority (79.4%) were classified as high dependency. ----- Intervention: Residents from four nursing homes were randomly selected for a nutrition education program coordinated by Nutrition Coordinators. Residents from the other four nursing homes (control) received usual care. ----- Measurements: The Subjective Global Assessment was used to determine prevalence of malnutrition at baseline and six months post intervention. The Resident Classification Scale measured functional dependency. Prescribed diet, fluids, oral hygiene status and allied health referrals were obtained by chart audit. ----- Results: Approximately half the residents were well nourished with 49.4% moderately or severely malnourished. Residents in the intervention group were more likely to maintain or improve their nutritional status compared with the control group who were more likely to experience a deterioration (P=0.027). The odds of the control group being malnourished post test was 1.6 times more likely compared with the intervention group but this did not reach statistical significance (P=0.1). ----- Conclusion: The results of the study encourage the implementation of a Nutrition Coordinator program to maintain nutritional status of aged care residents. Nevertheless, malnutrition rates continue to be unacceptably high. In a rapidly aging society, the aged care sector needs to confront malnutrition and provide better resources for staff to take measures against this problem.

The bondage of an imposed visual discourse : understanding the built environment's influence on the 'oldest-old' aged care residents' sense of peace

This study investigates the influence of the built environment upon residents' sense of familiarity, concept of self and thus, their facilitation of place through the theory of "The Bondage of Imposed Visual Discourse". Simone de Beauvoir's theory "The Bondage of Feminine Elegance" provides the conceptual understanding of the visual discourse between the physicality of clothing and the wearer's personal identity. This fashion theory is transposed to explore the influence of the built environment's physicality upon aged care residents' personal identity. This paper presents findings from a study of professionals' opinions in reference to the built environment of permanent residential aged care for the 'oldest-old' of Australia. The researcher conducted qualitative interviews with four participants: an architect, occupational therapist, nursing home facility manager and an aged care lobbyist in the South-East Queensland. This study is structured towards proposing "place-focused" qualitative design principles to encourage residents' sense of place through the built environment. These proposed principles are addressed with reference to existing Standards and Principles outlined by the Australian Government.

An individualized psychosocial approach for "treatment resistant" behavioral symptoms of dementia among aged care residents

Background: Behavioral symptoms of dementia are common among residents in mainstream aged care settings, and have a substantial impact on residents and professional caregivers. This study evaluated the impact of individualized psychosocial interventions for behavioral symptoms through a small preliminary study.
Method: Interventions were delivered to a patient group of 31 psychogeriatric aged care residents who presented with behavioral symptoms of dementia that had failed to respond to pharmacological treatment approaches. Outcome data on severity of behaviors, health service utilization and staff burden of care were collected.
Results: A modest but significant reduction in staff ratings of the severity of aggressive and verbally agitated behavioral symptoms was found, with an associated reduction in their perceptions of the burden of caring for these patients. Reduced behavioral disturbance was associated with a reduction in the requirement for primary care consultations, and all participants were able to continue to reside in mainstream aged care facilities, despite an increase in the severity of dementia.
Conclusions: This study supported the use of individualized psychological strategies for behavioral symptoms at all stages of dementia. Methodological limitations of this preliminary study are discussed.

Federally funded aged care provision in regional Victoria : Examining current provision and estimating future infrastructure requirements using existing population-based benchmarks

The following paper examines federally accredited and funded aged care provision in regional Victoria. Benchmarks that have been set by the Australian Department of Health and Ageing, are used to measure and compare the relative number of high and low level aged care positions and Community Aged Care Packages in six regional Victorian centres.
Using population forecasts, the additional aged care positions that each centre will require to meet the provision benchmarks in the year 2021 have been estimated. These figures are then translated into infrastructure requirements for the regional Victorian city of Greater Bendigo. This is done by surveying Greater Bendigo’s existing residential aged care facilities. Strategies for the provision of additional high and low level residential aged care infrastructure are explored using a matrix governed by size and configuration. Variations in these two aspects are shown to affect the location options for future facilities in Greater Bendigo. The implications of the benchmarks are also investigated in terms of facilities for the provision of Community Aged Care Packages.
The research is funded by a double ARC APAI grant between the Built Environment Research Group at Deakin University, The Centre for Sustainable Regional Centres at La Trobe University, the City of Greater Bendigo and the City of Warrnambool.

Multivitamin supplementation improves nutritional status and bone quality in aged care residents

Objectives: To assess the effectiveness of a multivitamin (MV) tablet on nutritional status, quantitative heel ultrasound (QUS), mobility, muscle strength and falls. The design comprised two groups matched on mobility levels, randomized to receive a daily MV or placebo (P) tablet for 6 months. The setting was an Australian residential care facility.

Subjects: A total of 92 aged care residents. Serum micronutrients, body weight, QUS, rate of falls, hand grip strength, and the timed up and go test were assessed at baseline and 6 months.

Results: A total of 49 participants consumed a MV and 43, a matched P for 6 months. There was a greater increase in the MV vs P group for serum 25(OH)D (mean differencestandard error, 33.42.6 nmol l-1), folate (13.42.8 nmol l-1), and vitamin B12 (178.040.3 pmol l-1) (all P<0.001). Adequate 25(OH)D concentrations (50 nmol l-1) were found among 77% of participants in the MV group vs 10% taking P (P<0.001). Adjusting for baseline levels, the increase in QUS was greater in the MV vs P group (3.02.0 dB MHz-1 vs -2.92.1 dB MHz-1, respectively, P=0.041). There was a trend towards a 63% lower mean number of falls in the MV vs P group (0.30.1 falls vs 0.80.3 falls, P=0.078).

Conclusions: MV supplementation raised serum vitamin B12 and folate concentrations and increased serum 25(OH)D, which was accompanied by an apparent positive effect on bone density. We also found a trend towards a reduction in falls and this could contribute to a reduction in fractures.
