Staff compliance with protocols to improve the management of behavioral and psychological symptoms of dementia

Using data from a larger study investigating the effectiveness of a structured clinical protocol to manage individuals in residential facilities who experience behavioral and psychological symptoms of dementia (BPSD), the current study investigated whether external clinical support in using the protocol with specific residents increased compliance in its use, over and above only providing a generic workshop about the protocol and management of BPSD. Results indicated that provision of the workshop, in addition to clinical support, was associated with significantly higher compliance. However, compliance was only found to be related to positive outcomes when staff received the generic workshop and not clinical support. When clinical support was provided, compliance was not related to outcomes or worse outcomes. These findings, when considered in the context of the results of the larger trial, suggest that the relationship among clinical support, compliance with BPSD protocols, and clinical outcomes for residents and staff is complex and needs further investigation.

Transitioning from caregiver to visitor in a long-term care facility: the experience of caregivers of people with dementia

Objectives: Transitioning from the primary caregiver to the visitor in a long-term care facility may be challenging for the caregiver; they are required to surrender their caring duties to the medical and nursing staff. The aim of this study was to explore the experiences of caregivers during their transition from day-to-day caregiver of a person with dementia to a visitor in a long-term care facility.

Methods: This study utilised a qualitative descriptive design. Twenty caregivers of people with dementia were recruited from the one Aged Rehabilitation and Geriatric Evaluation and Management facility, located in Victoria, Australia. Semi-structured interviews were used to explore the caregiver's experiences. Interviews were analysed using thematic analysis.

Results: The interview data revealed that the participants were undergoing similar experiences. The findings revealed that it was difficult for the caregiver to transition to their new role of visitor; negative reactions of grief, loss of motivation and loneliness were also coupled with positive feelings of relief and the reassurance that their relative or friend would be well cared for and safe within the long-term care facility.

Conclusion: The findings offer insight into the experiences felt by caregivers when their relative or friend with dementia is admitted to hospital. Implications of this study include the need to improve the transition process for the caregiver by allowing them to be involved in the decision-making process, keeping them informed of care decisions, and importantly, providing emotional support to help the caregiver positively adapt to this transition.

People with dementia and the hospital environment: the view of patients and family carers

Background

A metropolitan geriatric evaluation and management (GEM) facility in Australia was undergoing expansion, and consideration for the needs of individuals with dementia and their family carers was identified as important in planning the new facility. Existing literature revealed that people in hospital value privacy, minimal noise, family amenities and homeliness, but these findings did not consider the perspectives of the person with dementia specifically.

Aim

The aim was to elicit the perspectives of current inpatients with dementia, and their family carers, about the environment/design features that they believe are necessary for people with dementia, and their family carers.

Method and design

This qualitative study utilised in-depth semi-structured interviews to obtain information from current inpatients with dementia and their family carers.

Results

Participants described how the care received was more important than the physical environment; however, participants also valued homeliness, privacy for the patient and for conversations, a shared space without a television and a connection to the outside. Participants described how accommodating carers, providing quiet spaces and appropriate amenities were also important.

Conclusions

While participants valued care over the physical surroundings, they also offered valuable information about their experience in the ward environment. Despite cognitive difficulties, people with dementia were able to provide useful information about the environment within which they were being cared.

Implications for practice

Consumer opinions about hospital design/environment should be considered as an important source of data. Privacy and personal space for people with dementia and their family carers, a connection with the outside environment , and the needs of carers and visitors are all important considerations when designing healthcare environments.

The experience of family carers of people with dementia who are hospitalised

Hospital admission of a person with dementia can have a significant impact on the family carer, who temporarily relinquishes caring to health professionals. A descriptive qualitative design using in-depth interviews with a conversational approach was used to elicit data. Adjusting to the change in the carer’s role can be challenging and result in feelings of helplessness, loneliness, loss of control and being undervalued. Family support can assist with the transition but family conflict increases anxiety. Good communication between clinicians and the carer is vital. The carer should be included in decision-making as the ‘expert' in the care of the person with dementia. This article discusses findings of a larger study specifically related to the emotional support required for the carers of people with dementia, who are admitted to hospital. The carer and the patient must be considered as a dyad in relation to discharge planning.

Transferring from an acute hospital and settling into a subacute facility: the experience of patients with dementia

Background.  In a Melbourne metropolitan health network, patients with dementia can have difficulty settling into a subacute rehabilitation facility after transfer from the acute hospital.

Aims and objectives.  To understand how older patients with mild to moderate dementia experienced the transfer from acute to subacute care and settling-in period.

Design.  A descriptive design was used. Eight patients with mild to moderate dementia were recruited, one to 5 days after transfer.

Method.  A qualitative method using in-depth interviews was used. The data were analysed using content analysis.

Results.  Four main themes were identified: ‘Settling into a new environment’, ‘staff attitudes to people with dementia’, ‘loss of control’ and ‘family support’.

Conclusions.  Person-centred care that comes from the perspective of respect for the individual transcends all these issues. People with dementia require more support to settle after transfer. Family involvement can assist in facilitating a smooth transition.

Implications for practice.  Nurses who understand the specific needs of patients with dementia can develop ways of working with patients to ensure person-centred care. More conversations with people with dementia are needed to investigate how this can be achieved. Orientation procedures should ensure that support for people with dementia is optimized during the settling-in phase.

Organizational climate and self-efficacy as predictors of staff strain in caring for dementia residents: a mediation model

PURPOSE OF THE STUDY: To date, no research has investigated how the organizational climate of aged care influences the self-efficacy of staff in caring for residents with dementia, or, how self-efficacy is associated with the strain experienced by staff. This study sought to investigate the extent to which the self-efficacy of aged care staff mediates the association between organizational climate variables (such as autonomy, trusting and supportive workplace relations, and the recognition of competence and ability, and perceptions of workplace pressure) and staff strain. DESIGN AND METHODS: A cross-sectional survey design was implemented in which 255 residential aged care staff recruited across aged care facilities in Melbourne, Australia. Staff completed self-report measures of organizational climate, self-efficacy, and strains in caring for residents with dementia. RESULTS: Indirect effects analyses using bootstrapping indicated that self-efficacy of staff mediated the association between the organizational climate variables of autonomy, trust, support, pressure, and staff strain. IMPLICATIONS: The findings of this study emphasize that the aged care sector needs to target organizational climate variables that enhance the self-efficacy of staff, and that this in turn, can help ameliorate the strain experienced by staff caring for residents experiencing dementia.

Assessing financial competence in older adults with cognitive impairment

One common problem brought before Courts and Tribunals in Australia is whether or not someone is able to manage his or her own financial affairs. The problem is that currently in Australia there are no universally agreed upon standards for assessing financial competence. The aim of this study was to examine the reliability and validity of a new measure of financial competence, The Financial Competence Assessment Inventory (FCAI), in assessing financial competency of older adults with a cognitive impairment. The sample comprised 18 older adults with acquired brain injury, 10 adults with schizophrenia, 21 adults with dementia and 27 older adults without cognitive impairment. Ages ranged from 55 to 91. Each participant was individually interviewed using the FCAI. The findings revealed that the FCAI is a reliable and valid assessment tool for assessing financial competence of older adults with different types and levels of cognitive impairment. In particular, the FCAI was able to distinguish between older adults with global brain impairment and older adults with specific brain impairment; and older adults who had a legal administrator and older adults who did not. In addition, using the FCAI it was possible to obtain a profile of participants’ strengths and weaknesses across six domains of financial competence including; everyday financial abilities, financial judgment, estate management, cognitive based financial tasks, debt management, and support resources. The FCAI has the potential to assist clinicians and legal decision-makers regarding ‘least restrictive alternatives’ when financial competence is in question.

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.

Perinatal ω-3 polyunsaturated fatty acid supply modifies brain zinc homeostasis during adulthood

Dietary ω-3 polyunsaturated fatty acid (PUFA) influences the expression of a number of genes in the brain. Zinc transporter (ZnT) 3 has been identified as a putative transporter of zinc into synaptic vesicles of neurons and is found in brain areas such as hippocampus and cortex. Neuronal zinc is involved in the formation of amyloid plaques, a major characteristic of Alzheimer's disease. The present study evaluated the influence of dietary ω-3 PUFA on the expression of the ZnT3 gene in the brains of adult male Sprague-Dawley rats. The rats were raised and/or maintained on a control (CON) diet that contained ω-3 PUFA or a diet deficient (DEF) in ω-3 PUFA. ZnT3 gene expression was analyzed by using real-time PCR, free zinc in brain tissue was determined by zinquin staining, and total zinc concentrations in plasma and cerebrospinal fluid were determined by atomic absorption spectrophotometry. Compared with CON-raised animals, DEF-raised animals had increased expression of ZnT3 in the brain that was associated with an increased level of free zinc in the hippocampus. In addition, compared with CON-raised animals, DEF-raised animals had decreased plasma zinc level. No difference in cerebrospinal fluid zinc level was observed. The results suggest that overexpression of ZnT3 due to a perinatal ω-3 PUFA deficiency caused abnormal zinc metabolism in the brain. Conceivably, the influence of dietary ω-3 PUFA on brain zinc metabolism could explain the observation made in population studies that the consumption of fish is associated with a reduced risk of dementia and Alzheimer's disease.

Cross-national compartability of burden of disease estimates:the European disability weights project

Objective: To investigate the sources of cross-national variation in disability-adjusted life-years (DALYs) in the European Disability
Weights Project.

Methods: Disability weights for 15 disease stages were derived empirically in five countries by means of a standardized procedure and the cross-national differences in visual analogue scale (VAS) scores were analysed. For each country the burden of dementia in women, used as an illustrative example, was estimated in DALYs. An analysis was performed of the relative effects of cross-national variations in demography, epidemiology and disability weights on DALY estimates.

Findings: Cross-national comparison of VAS scores showed almost identical ranking orders. After standardization for population size and age structure of the populations, the DALY rates per 100 000 women ranged from 1050 in France to 1404 in the Netherlands. Because of uncertainties in the epidemiological data, the extent to which these differences reflected true variation between countries was difficult to estimate. The use of European rather than country-specific disability weights did not lead to a significant change in the burden of disease estimates for dementia.

Conclusions: Sound epidemiological data are the first requirement for burden of disease estimation and relevant between-countries comparisons. DALY estimates for dementia were relatively insensitive to differences in disability weights between European countries.

The effects of a simplified tai-chi exercise program (STEP) on the physical health of older adults living in long-term care facilities : a single group design with multiple time points

Background
Studies support the positive effects that Tai Chi has on the physical health of older adults. However, many older adults residing in long-term care facilities feel too weak to practice traditional Tai Chi, and a more simplified style is preferred.
Objective
To test the effects of a newly-developed, Simplified Tai-Chi Exercise Program (STEP) on the physical health of older adults who resided in long-term care facilities.
Design
A single group design with multiple time points: three pre-tests, one month apart; four post-tests at one month, two months, three months, and six months after intervention started.
Settings
Two 300–400 bed veteran homes in Taiwan.
Participants
The 51 male older adults were recruited through convenience sampling, and 41 of them completed six-month study. Inclusion criteria included: (1) aged 65 and over; (2) no previous training in Tai Chi; (3) cognitively alert and had a score of at least eight on the Short Portable Mental Status Questionnaire; (4) able to walk without assistance; and (5) had a Barthel Index score of 61 or higher. Participants who had dementia, were wheel-chair bound, or had severe or acute cardiovascular, musculoskeletal, or pulmonary illnesses were excluded.
Methods
The STEP was implemented three times a week, 50 min per session for six months. The outcome measures included cardio-respiratory function, blood pressure, balance, hand-grip strength, lower body flexibility, and physical health actualization.
Results
A drop in systolic blood pressure (p=.017) and diastolic blood pressure (p<.001) was detected six months after intervention started. Increase in hand-grip strength from pre to post intervention was found (left hand: p<.001; right hand: p=.035). Participants also had better lower body flexibility after practicing STEP (p=.038).
Conclusions
Findings suggest that the STEP be incorporated as a floor activity in long-term care facilities to promote physical health of older adults.

A brief introduction to the history of the ß-amyloid protein (Aß) of Alzheimer's disease

Alzheimer’s disease (AD) is the most common cause of dementia in the elderly. Typically, the disease progresses in a prolonged, inexorable manner [1]. Patients initially show symptoms of mild cognitive impairment, which may include some memory loss. As the disease progresses, more severe memory loss occurs (e.g., retrograde amnesia) leading to confusion and lack of orientation. The patient is often institutionalized in this period, as it becomes increasingly difficult for family members to cope with the constant requirements of care. In later stages of the disease, apathy and stupor can occur, and the patient becomes bedridden.
