Preferences and Perspectives of Australian General Practitioners Towards a New "Four-in-One" Risk Assessment Tool for Preventative Health: The LEAD! GP Project.

BACKGROUND: Dementia risk reduction is a public health priority and general practitioners (GPs) play a pivotal role in preventative healthcare. Therefore, risk assessment tools should be designed with GPs' preferences and perspectives in mind. OBJECTIVE: The LEAD! GP project aimed to investigate Australian GPs' preferences and perspectives relating to design, use and implementation of a new risk assessment tool that simultaneously calculates risk for four outcomes- dementia, diabetes mellitus, myocardial infarct, and stroke. METHODS: A mixed methods study using semi-structured interviews of a diverse group of 30 Australian GPs was conducted. Interview transcripts were analyzed thematically. Demographics and questions that elicited categorical answers were analyzed descriptively. RESULTS: Overall, GPs felt that preventative healthcare was important with some finding it rewarding, and others finding it difficult. GPs currently use many risk assessment tools. GPs' perception of the usefulness and negatives/barriers of tools related to clinical practice applicability, patient engagement, and practical aspects. The largest barrier was lack of time. GPs responded positively to the concept of a four-in-one tool and preferred it to be relatively short, supported by practice nurses and some patient involvement, linked to education resources, available in different formats, and integrated into practice software. CONCLUSION: GPs recognize the importance of preventative healthcare and the potential benefit of a new tool that simultaneously predicts risk for those four outcomes. Findings provide important guidance to inform the final development and piloting of this tool with potential to improve efficiency and practical integration of preventative healthcare for dementia risk reduction.

Assessment of the DTI-ALPS Parameter Along the Perivascular Space in Older Adults at Risk of Dementia.

BACKGROUND AND PURPOSE: Recently, there has been growing interest in the glymphatic system (the functional waste clearance pathway for the central nervous system and its role in flushing solutes (such as amyloid ß and tau), metabolic, and other cellular waste products in the brain. Herein, we investigate a recent potential biomarker for glymphatic activity (the diffusion tensor imaging along the perivascular space [DTI-ALPS] parameter) using diffusion MRI imaging in an elderly cohort comprising 10 cognitively normal, 10 mild cognitive impairment (MCI), and 16 Alzheimer's disease (AD). METHODS: All 36 participants imaged on a Siemens 3.0T Tim Trio. Single-SE diffusion weighted Echo-planar imaging scans were acquired as well as T1 magnetization prepared rapid gradient echo, T2 axial, and susceptibility weighted imaging. Three millimeter regions of interest were drawn in the projection and association fibers adjacent to the medullary veins at the level of the lateral ventricle. The DTI-ALPS parameter was calculated in these regions and correlated with cognitive status, Mini-Mental State Examination (MMSE), and ADASCog11 measures. RESULTS: Significant correlations were found between DTI-ALPS and MMSE and ADASCog11 in the right hemisphere adjusting for age, sex, and APoE ε4 status. Significant differences were also found in the right DTI-ALPS indices between cognitively normal and AD groups (P < .026) and MCI groups (P < .025) in a univariate general linear model corrected for age, sex, and APoE ε4. Significant differences in apparent diffusion coefficient between cognitively normal and AD groups were found in the right projection fibers (P = .028). CONCLUSION: Further work is needed to determine the utility of DTI-ALPS index in larger elderly cohorts and whether it measures glymphatic activity.

A pilot study exploring staff acceptability of a socially assistive robot in a residential care facility that accommodates people under 65 years old.

ABSTRACTSocially assistive robots have successfully been trialed in residential care facilities (RCFs) for older adults. These robots may have potential for younger adults (i.e. under 65 years old) who also live in RCFs. However, it is important to investigate staff acceptability and ease-of-use of these robots. This pilot study used the Technology Acceptance Model to investigate how staff working in a specialized RCF for younger adults accept Betty, a socially assistive robot who was introduced in the facility for 12 weeks. Twenty-four staff completed pre-questionnaires, reporting that they thought Betty would have the ability to engage and entertain the residents they cared for. While there were only eight staff who completed the post-questionnaires, there were significant improvements compared to the pre-questionnaire results in areas such as residents enjoying the contact and activities. Impacting on ease-of use were technical difficulties. Although this study had limitations and could be improved by a better response rate and investigating the residents' acceptability of Betty, this study is one of the first to report that this novel technology may have much potential for engaging adults in RCFs.

A pilot study investigating the feasibility of symptom assessment manager (SAM), a Web-based real-time tool for monitoring challenging behaviors.

OBJECTIVE: Improving and minimizing challenging behaviors seen in psychiatric conditions, including behavioral and psychological symptoms of dementia are important in the care of people with these conditions. Yet there is a lack of systematic evaluation of these as a part of routine clinical care. The Neuropsychiatric Inventory is a validated and reliable tool for rating the severity and disruptiveness of challenging behaviors. We report on the evaluation of a Web-based symptom assessment manager (SAM), designed to address the limitation of previous tools using some of the Neuropsychiatric Inventory functions, to monitor behaviors by staff caring for people with dementia and other psychiatric conditions in inpatient and residential care settings. METHODS: The SAM was piloted in an 8-bed inpatient neuropsychiatry unit over 5 months. Eleven nurses and 4 clinicians were trained in usage of SAM. Primary outcomes were usage of SAM and perceived usability, utility, and acceptance of SAM. Secondary outcomes were the frequencies of documented behavior. Usage data were analyzed using chi-square and logistic regression analyses. RESULTS: The SAM was used for all admitted patients regardless of diagnosis, with a usage rate of 64% for nurses regularly employed in the unit. Staff provided positive feedback regarding the utility of SAM. CONCLUSIONS: The SAM appeared to offer individualized behavior assessment by providing a quick, structured, and standardized platform for assessing behavior in a real-world setting. Further research would involve trialing SAM with more staff in alternative settings such as in home or residential care settings.

Associations of neighborhood environment with brain imaging outcomes in the Australian Imaging, Biomarkers and Lifestyle cohort.

INTRODUCTION: "Walkable" neighborhoods offer older adults opportunities for activities that may benefit cognition-related biological mechanisms. These have not previously been examined in this context. METHODS: We objectively assessed neighborhood walkability for participants (n = 146) from the Australian Imaging, Biomarkers and Lifestyle study with apolipoprotein E (APOE) genotype and two 18-month-apart brain volumetric and/or amyloid ß burden assessments. Linear mixed models estimated associations of neighborhood walkability with levels and changes in brain imaging outcomes, the moderating effect of APOE ε4 status, and the extent to which associations were explained by physical activity. RESULTS: Cross-sectionally, neighborhood walkability was predictive of better neuroimaging outcomes except for left hippocampal volume. These associations were to a small extent explained by physical activity. APOE ε4 carriers showed slower worsening of outcomes if living in walkable neighborhoods. DISCUSSION: These findings indicate associations between neighborhood walkability and brain imaging measures (especially in APOE ε4 carriers) minimally attributable to physical activity.

The Stroke and Carer Optimal Health Program (SCOHP) to enhance psychosocial health: study protocol for a randomized controlled trial.

BACKGROUND: Stroke is a leading cause of disability and distress, and often profoundly affects the quality of life of stroke survivors and their carers. With the support of carers, many stroke survivors are returning to live in the community despite the presence of disability and ongoing challenges. The sudden and catastrophic changes caused by stroke affects the mental, emotional and social health of both stroke survivors and carers. The aim of this study is to evaluate a Stroke and Carer Optimal Health Program (SCOHP) that adopts a person-centred approach and engages collaborative therapy to educate, support and improve the psychosocial health of stroke survivors and their carers. METHODS: This study is a prospective randomised controlled trial. It will include a total of 168 stroke survivors and carers randomly allocated into an intervention group (SCOHP) or a control group (usual care). Participants randomised to the intervention group will receive nine (8 + 1 booster) sessions guided by a structured workbook. The primary outcome measures for stroke survivors and carers will be health-related quality of life (AQoL-6D and EQ-5D) and self-efficacy (GSE). Secondary outcome measures will include: anxiety and depression (HADS); coping (Brief COPE); work and social adjustment (WSAS); carer strain (MCSI); carer satisfaction (CASI); and treatment evaluation (TEI-SF and CEQ). Process evaluation and a health economic cost analysis will also be conducted. DISCUSSION: We believe that this is an innovative intervention that engages the stroke survivor and carer and will be significant in improving the psychosocial health, increasing independence and reducing treatment-related costs in this vulnerable patient-carer dyad. In addition, we expect that the intervention will assist carers and stroke survivors to negotiate the complexity of health services across the trajectory of care and provide practical skills to improve self-management.

Road safety in an aging population: risk factors, assessment, interventions, and future directions.

With the number of older drivers projected to increase by up to 70% over the next 20 years, preventing injury resulting from crashes involving older drivers is a significant concern for both policy-makers and clinicians. While the total number of fatal crashes per annum has steadily decreased since 2005 in Australia, the rate of fatalities has demonstrated an upward trend since 2010 in drivers aged 65 years and above (8.5 per 100,000), such that it is now on par with the fatality rate in drivers aged 17-25 years (8.0 per 100,000) (Austroads, 2015). Similar statistics are reported for the United States (NHTSA, 2012), implying there is a need for better identification of those older drivers who are unsafe and implementation of strategies that can enhance mobility while maximizing road safety.

Bridging the Translation Gap: From Dementia Risk Assessment to Advice on Risk Reduction.

Dementia risk reduction is a global health and fiscal priority given the current lack of effective treatments and the projected increased number of dementia cases due to population ageing. There are often gaps among academic research, clinical practice, and public policy. We present information on the evidence for dementia risk reduction and evaluate the progress required to formulate this evidence into clinical practice guidelines. This narrative review provides capsule summaries of current evidence for 25 risk and protective factors associated with AD and dementia according to domains including biomarkers, demographic, lifestyle, medical, and environment. We identify the factors for which evidence is strong and thereby especially useful for risk assessment with the goal of personalising recommendations for risk reduction. We also note gaps in knowledge, and discuss how the field may progress towards clinical practice guidelines for dementia risk reduction.

The adverse mental health of carers: Does the patient diagnosis play a role?

OBJECTIVES: The adverse mental health effects of caring have been studied, frequently in carers of people with dementia. Less is known about the mental health of carers of people with other conditions. This study compared depression and burden in older carers looking after people with a variety of conditions. DESIGN, METHODS AND MEASURES: Over 200 older carers interested in participating in the Improving Mood through Physical Activity in Carers and Care-recipient Trial were included in this cross-sectional study, using the Geriatric Depression Scale (GDS) and Zarit Burden Inventory (ZBI). RESULTS: Overall there were 43% of carers who were depressed and a quarter of them reported moderate-to-severe burden. Carers of people with physical conditions had the highest levels of depression and burden. Patient diagnosis, hours spent caring, and burden were associated with depression, while hours spent caring and carer depression were associated with burden. These factors contributed approximately 25-30% of the variance of depression and burden, respectively. CONCLUSIONS: The diagnosis of the patient was a factor associated with depression, and older carers of people with physical conditions were at the highest risk. It is important for clinicians to assess the mental health of all carers, regardless of the patient diagnosis.

Exploring health care providers' perceptions of the needs of stroke carers: informing development of an optimal health program.

BACKGROUND: Health care provider experiences of the carer have been researched, but little is written about how these can inform development of support programs. OBJECTIVES: This study aimed to (1) explore health care provider perceptions of stroke carer roles and support needs and (2) examine carer needs across the stroke care trajectory to assist with development of an Optimal Health Program (OHP) to support carers. This study is part of a staged program of research that will evaluate and refine the OHP. METHODS: Four dual-moderated semi-structured focus groups of stroke health care providers across acute, subacute, and community rehabilitation services were conducted. Facilitators used a semi-structured focus group schedule to guide discussion. Sessions were recorded, transcribed, and analyzed using thematic and content analysis. RESULTS: Three key themes emerged: transition, information, and impact of stroke. A number of subthemes highlighted the distinct roles of health care providers and carers. Specific elements of the OHP were identified as having the potential to advance support for carers across the stroke care trajectory. DISCUSSION: Findings support the integration of an OHP for carers within existing stroke care services in Australian public hospital and community settings. CONCLUSION: This study suggests how health care provider experiences could inform a self-management OHP to assist carers in navigating stroke services and to address their health-related concerns.

Non-pharmacological strategies to delay cognitive decline.

Non-pharmacological preventive strategies to delay cognitive decline have become the focus of recent research. This review aims to discuss evidence supporting the use of physical and cognitive activity to reduce the risk of cognitive decline and dementia in later life. Both strategies are associated with better cognitive health in older adults. This positive effect seems stronger for middle-aged and older adults with normal cognition and less clear when cognitive impairment is present. Physical and cognitive activities have been linked to indirect and direct biological factors affecting brain health. Future research will need to explore details about type, intensity, duration and combination of interventions. An important aim is standardization between studies, as well as evidence of improved clinical outcomes and cost-effectiveness. Identifying strategies that succeed at sustaining improved lifestyle is necessary, and the use of modern technology could play a crucial role in this regard. In the meantime advice on physical and cognitive activities should be included when health advice is given to middle-aged and older adults.

Pastoral care in old age psychiatry: addressing the spiritual needs of inpatients in an acute aged mental health unit.

INTRODUCTION: Pastoral Care (PC) practitioners respond to the spiritual needs of patients and families of all spiritual orientations. The integrated PC service in an acute psychogeriatric inpatient ward at St Vincent's Aged Mental Health Service, Melbourne, Australia, was examined to investigate how PC was being accessed by inpatients. METHODS: A retrospective medical record file audit was undertaken of patients admitted over a 16-month period from 1 February 2009 to 30 June 30 2010 (n = 202). RESULTS: Sixty-eight percent were seen by PC practitioners during their admission. Sixty-six percent received PC assessments, 32% received PC ministry, and 10% received PC ritual or worship interventions. Other interventions (counseling/education, crisis situation, grief/ bereavement counseling) occurred infrequently. Seventy-five percent of Roman Catholic patients received PC compared to 57% of those patients with no religious affiliation. However, the overall association between religious grouping and receiving PC was not significant. Gender, religion, marital status, legal status, country of birth, language spoken, living situation, carer needs, or educational level were not related to PC contact. Whether or not an inpatient received PC assessment was unrelated to diagnostic category. Patients seen by PC were significantly more likely to engage in religious practice, have longer length of stay, and have neuropsychological, social work and occupational therapy assessments. DISCUSSION: Results suggest that PC practitioners can help optimize the clinical care of patients by developing a comprehensive understanding of their spiritual and religious needs and providing a more holistic service.

Personality of mental health caregivers.

PURPOSE OF REVIEW: Caring for a family member with a chronic mental illness can be a major challenge with putting caregivers at risk of burden and depression. This review investigated the recent evidence on the role of personality traits and features for caregiver burden and depression in caregivers of care recipients with mental illness. RECENT FINDINGS: Most of the evidence was found for caregivers looking after care recipients with dementia. Neuroticism was the personality trait showing the strongest association with caregiver burden and depression. SUMMARY: Certain personality traits and features can increase the risk of caregiver burden and depression in caregivers looking after family members with a mental illness. More research is needed especially focusing on caregivers looking after care recipients with mental illnesses other than dementia as well as on interventions aiming to support vulnerable caregivers.

Factors associated with suicidal thoughts in a large community study of older adults.

BACKGROUND: Thoughts about death and self-harm in old age have been commonly associated with the presence of depression, but other risk factors may also be important. AIMS: To determine the independent association between suicidal ideation in later life and demographic, lifestyle, socioeconomic, psychiatric and medical factors. METHOD: A cross-sectional study was conducted of a community-derived sample of 21 290 adults aged 60-101 years enrolled from Australian primary care practices. We considered that participants endorsing any of the four items of the Depressive Symptom Inventory -Suicidality Subscale were experiencing suicidal thoughts. We used standard procedures to collect demographic, lifestyle, psychosocial and clinical data. Anxiety and depressive symptoms were assessed with the Hospital Anxiety and Depression Scale. RESULTS: The 2-week prevalence of suicidal ideation was 4.8%. Male gender, higher education, current smoking, living alone, poor social support, no religious practice, financial strain, childhood physical abuse, history of suicide in the family, past depression, current anxiety, depression or comorbid anxiety and depression, past suicide attempt, pain, poor self-perceived health and current use of antidepressants were independently associated with suicidal ideation. Poor social support was associated with a population attributable fraction of 38.0%, followed by history of depression (23.6%), concurrent anxiety and depression (19.7%), prevalent anxiety (15.1%), pain (13.7%) and no religious practice (11.4%). CONCLUSIONS: Prevalent and past mood disorders seem to be valid targets for indicated interventions designed to reduce suicidal thoughts and behaviour. However, our data indicate that social disconnectedness and stress account for a larger proportion of cases than mood disorders. Should these associations prove to be causal, then interventions that succeeded in addressing these issues would contribute the most to reducing suicidal ideation and, possibly, suicidal behaviour in later life.

Premorbid personality traits are associated with post-stroke behavioral and psychological symptoms: a three-month follow-up study in Perth, Western Australia.

BACKGROUND: Previous research has found an association between post-stroke depressive symptoms and premorbid personality. This study sought to investigate further the relationship between premorbid personality and a number of common post-stroke behavioral and psychological symptoms in a three-month follow-up study. METHODS: This prospective study was conducted between May 2003 and January 2005 in a Perth metropolitan teaching hospital. The pre-stroke personality of stroke survivors was assessed by interviewing a close family member (informant) within four weeks of the index stroke using the NEO Personality Inventory-Revised. Three months after the stroke, patients were followed up and assessed with the Cambridge Cognitive examination and Hospital Anxiety and Depression Scale, and their informants completed the Neuropsychiatric Inventory-carer distress version (NPI) and instrumental activities of daily living scale. RESULTS: Depressive symptoms were the most commonly reported post-stroke symptom (45.1%). Spearman's correlations showed that high neuroticism was positively correlated with NPI total scores (rho = 0.37, p = 0.007), NPI total distress scores (rho = 0.47, p = 0.001), and specifically with agitation and irritability NPI composite scores. Agreeableness was inversely correlated with agitation (rho = -0.40, p = 0.004) and irritability (rho = -0.37, p = 0.007) composite scores. CONCLUSIONS: Premorbid personality traits of high neuroticism and low agreeableness are associated with the presence of post-stroke agitation, irritability, and carer distress. This knowledge may contribute to the development of strategies designed to identify patients and families who require more intense supervision and support during post-stroke rehabilitation.
