Australian long-term care personnel's knowledge and attitudes regarding palliative care for people with advanced dementia

This study aimed to describe Australian long-term care (LTC) personnel's knowledge and attitudes concerning palliative care for residents with advanced dementia, and explore relationships with LTC facility/personnel characteristics. An analysis was undertaken of baseline data from a cluster randomised controlled trial of facilitated family case conferencing for improving palliative care of LTC residents with advanced dementia (the 'IDEAL Study'). Participants included any LTC personnel directly involved in residents' care. Knowledge and attitudes concerning palliative care for people with advanced dementia were measured using the questionnaire on Palliative Care for Advanced Dementia. Univariate and multivariate analyses explored relationships between personnel knowledge/attitudes and facility/personnel characteristics. Of 307 personnel in the IDEAL Study, 290 (94.5%) from 19/20 LTCFs provided sufficient data for inclusion. Participants included 9 (2.8%) nurse managers, 59 (20.5%) registered nurses, 25 (8.7%) enrolled nurses, 187 (64.9%) assistants in nursing/personal care assistants and 9 (3.1%) care service employees. In multivariate analyses, a facility policy not to rotate personnel through dementia units was the only variable associated with more favourable overall personnel knowledge and attitudes. Other variables associated with favourable knowledge were a designation of nursing manager or registered or enrolled nurse, and having a preferred language of English. Other variables associated with favourable attitudes were tertiary level of education and greater experience in dementia care. Like previous international research, this study found Australian LTC personnel knowledge and attitudes regarding palliative care for people with advanced dementia to be associated with both facility and personnel characteristics. Future longitudinal research is needed to better understand the relationships between knowledge and attitudes, as well as between these attributes and quality of care.

Perspectives of people with dementia and carers on advance care planning and end-of-life care: A systematic review and thematic synthesis of qualitative studies

BACKGROUND:

Advance care planning aims to ensure that care received during serious and chronic illness is consistent with the person’s values, preferences and goals. However, less than 40% of people with dementia undertake advance care planning internationally.

AIM:

This study aims to describe the perspectives of people with dementia and their carers on advance care planning and end-of-life care.

DESIGN:

Systematic review and thematic synthesis of qualitative studies.

DATA SOURCES:

Electronic databases were searched from inception to July 2018.

RESULTS:

From 84 studies involving 389 people with dementia and 1864 carers, five themes were identified: avoiding dehumanising treatment and care (remaining connected, delaying institutionalisation, rejecting the burdens of futile treatment); confronting emotionally difficult conversations (signifying death, unpreparedness to face impending cognitive decline, locked into a pathway); navigating existential tensions (accepting inevitable incapacity and death, fear of being responsible for cause of death, alleviating decisional responsibility); defining personal autonomy (struggling with unknown preferences, depending on carer advocacy, justifying treatments for health deteriorations); and lacking confidence in healthcare settings (distrusting clinicians’ mastery and knowledge, making uninformed choices, deprived of hospice access and support at end of life).

CONCLUSION:

People with dementia and their carers felt uncertain in making treatment decisions in the context of advance care planning and end-of-life care. Advance care planning strategies that attend to people’s uncertainty in decision-making may help to empower people with dementia and carers and strengthen person-centred care in this context.

An Australian community jury to consider case-finding for dementia: Differences between informed community preferences and general practice guidelines

Background

Case‐finding for dementia is practised by general practitioners (GPs) in Australia but without an awareness of community preferences. We explored the values and preferences of informed community members around case‐finding for dementia in Australian general practice.

Design, setting and participants

A before and after, mixed‐methods study in Gold Coast, Australia, with ten community members aged 50‐70.

Intervention

A 2‐day citizen/community jury. Participants were informed by experts about dementia, the potential harms and benefits of case‐finding, and ethical considerations.

Primary and secondary outcomes

We asked participants, “Should the health system encourage GPs to practice ‘case‐finding’ of dementia in people older than 50?” Case‐finding was defined as a GP initiating testing for dementia when the patient is unaware of symptoms. We also assessed changes in participant comprehension/knowledge, attitudes towards dementia and participants’ own intentions to undergo case‐finding for dementia if it were suggested.

Results

Participants voted unanimously against case‐finding for dementia, citing a lack of effective treatments, potential for harm to patients and potential financial incentives. However, they recognized that case‐finding was currently practised by Australian GPs and recommended specific changes to the guidelines. Participants increased their comprehension/knowledge of dementia, their attitude towards case‐finding became less positive, and their intentions to be tested themselves decreased.

Conclusion

Once informed, community jury participants did not agree case‐finding for dementia should be conducted by GPs. Yet their personal intentions to accept case‐finding varied. If case‐finding for dementia is recommended in the guidelines, then shared decision making is essential.

Office-based assessment of cognitive impairment

BACKGROUND

Dementia is an increasingly prevalent condition, currently affecting over 400,000 Australians, and this is expected to rise to over one million by 2056. Diagnosis of dementia is a clinical one, as there is no single well-defined blood test, imaging or cognitive function test that validly diagnoses dementia. There are also many causes of cognitive impairment other than dementia, which need to be identified or excluded. General practitioners (GPs) are on the frontline of presentation and will therefore play an increasingly important role in identification and management.

OBJECTIVE

This article reviews what the GP can do in relation to office-based assessment for cognitive impairment.

DISCUSSION

Dementia is an increasingly common condition, and it is important that GPs become familiar with its assessment and management in order to optimise access to care services, advance care planning and management of other conditions for their patients.

Effectiveness of a peer-mediated educational intervention in improving general practitioner diagnostic assessment and management of dementia: a cluster randomised controlled trial

OBJECTIVE

Test effectiveness of an educational intervention for general practitioners (GPs) on quality of life and depression outcomes for patients.

DESIGN

Double-blind, cluster randomised controlled trial.

SETTING

General practices in Australia between 2007 and 2010.

PARTICIPANTS

General practices were randomly allocated to the waitlist (n=37) or intervention (n=66) group, in a ratio of 1:2. A total of 2030 (1478 intervention; 552 waitlist) community-dwelling participants aged 75 years or older were recruited via 168 GPs (113 intervention; 55 waitlist).

INTERVENTIONS

A practice-based academic detailing intervention led by a peer educator that included: (1) training in use of the GP assessment of cognition dementia screening instrument; (2) training in diagnosis and management based on Royal Australian College of General Practitioners Dementia Guidelines; (3) addressing GPs' barriers to dementia diagnosis; and (4) a business case outlining a cost-effective dementia assessment approach.

OUTCOME MEASURES

Primary outcome measures were patient quality of life and depression; secondary outcome measures were: (1) sensitivity and specificity of GP identification of dementia; (2) referral to medical specialists and/or support services; (3) patient satisfaction with care; and (4) carer quality of life, depression and satisfaction with care.

RESULTS

The educational intervention had no significant effect on patient quality of life or depression scores after 12 months. There were however improvements in secondary outcome measures including sensitivity of GP judgement of dementia (p=0.002; OR 6.0, 95% CI 1.92 to 18.73), satisfaction with GP communication for all patients (p=0.024; mean difference 2.1, 95% CI 0.27 to 3.93) and for patients with dementia (p=0.007; mean difference 7.44, 95% CI 2.02 to 12.86) and enablement of carers (p=0.0185; mean difference 24.77, 95% CI 4.15 to 45.40).

CONCLUSION

Practice-based academic detailing did not improve patient quality of life or depression scores but did improve detection of dementia in primary care and patient satisfaction with GP communication.

Potentially Inappropriate Prescribing in Australian Nursing Home Residents with Advanced Dementia: A Substudy of the IDEAL Study

BACKGROUND

Prescribing medications for nursing home residents with advanced dementia should focus on optimizing function and comfort, reducing unnecessary harms and aligning care goals with a palliative approach.

OBJECTIVE

The aim of the study was to estimate the proportion of Australian nursing home residents with advanced dementia receiving potentially inappropriate medications, and identify those most commonly prescribed and factors associated with their use.

DESIGN

Data were collected through retrospective audit of medication charts.

SETTING/SUBJECTS

Two hundred eighteen nursing home residents with advanced dementia from 20 nursing homes participated in a cluster-randomized controlled trial of case conferencing (the IDEAL Study) from June 2013 to December 2014.

MEASUREMENTS

Inappropriate drug use was defined as medications classified as "never appropriate" by the Palliative Excellence in Alzheimer Care Efforts (PEACE) program criteria. Generalized linear mixed models were used to identify variables predicting use of "never" appropriate medications.

RESULTS

Over a quarter (n = 65, 30%) of residents received at least one medication classed as "never" appropriate, the most common being lipid-lowering agents (n = 38, 17.4%), antiplatelet agents (n = 18, 8.3%), and acetylcholinesterase inhibitors (n = 16, 7.3%). Residents who had been at the nursing home for ≤10 months (odds ratio [OR] 5.60, 95% confidence interval [CI] 1.74-18.06) and 11-21 months (OR 5.41, 95% CI 1.67-17.75) had significantly greater odds of receiving a never appropriate medication compared with residents who had been at the nursing home for >5 years.

CONCLUSIONS

Use of potentially inappropriate medications in Australian nursing home residents with advanced dementia is common. A greater understanding of the rationale that underpins prescribing of medications is required.

Quality assessment of systematic reviews of vitamin D, cognition and dementia

BACKGROUND

There is conflicting evidence regarding the association of vitamin D with cognition performance and dementia.AimsWe aimed to summarise the evidence on the association of vitamin D with cognitive performance, dementia and Alzheimer disease through a qualitative assessment of available systematic reviews and meta-analyses.

METHOD

We conducted an overview of the systematic reviews of all study types with or without meta-analyses on vitamin D and either Alzheimer disease, dementia or cognitive performance up to June 2017.

RESULTS

Eleven systematic reviews were identified, nine of which were meta-analyses with substantial heterogeneity, differing statistical methods, variable methodological quality and quality of data abstraction. A Measurement Tool to Assess Systematic Reviews checklist scores ranged from 4 to 10 out of 11, with seven reviews of 'moderate' and four of 'high' methodological quality. Out of six meta-analyses on the association between low serum concentration of 25-hydroxyvitamin D and risk of dementia, five showed a positive association. Results of meta-analyses on the association between low serum concentration of 25-hydroxyvitamin D and memory function tests showed conflicting results.

CONCLUSIONS

This systematic evaluation of available systematic reviews provided a clearer understanding of the potential link between low serum vitamin D concentrations and dementia. This evaluation also showed that the quality of the available evidence is not optimal because of both the low methodological quality of the reviews and low quality of the original studies. Interpretation of these systematic reviews should therefore be made with care.Declaration of interestNone.

Understanding the conceptualisation of risk in the context of community dementia care

Risk has become a ubiquitous presence in modern society. For individuals diagnosed with dementia this preoccupation with risk can affect their day-to-day life in many ways. Maintaining autonomy while balancing risks is a continual struggle not only for those living with the disease, but also their carers, family and health professionals. To understand how these different groups of individuals conceptualise the issue of risk for those living with dementia, 83 semi-structured interviews were conducted with people living with dementia, carers, older people without significant experience of dementia, and registered nurses, and staff from a community nursing organisation. These interviews were analysed using Thematic Analysis, which suggested that the risks identified by each group were grounded in their experiences and perspective on dementia. Furthermore, context and understanding of the individual living with dementia and their preferences was central to effectively managing risk in a balanced way, ensuring that 'acceptable risks' were taken to ensure an acceptable quality of life for all involved. These findings highlight that there is no single approach to risk which can be applied to all individuals; rather, a negotiation needs to take place that takes into account the individual's preferences alongside their available resources and means.

Protocol for a pragmatic randomised controlled trial of Body Brain Life-General Practice and a Lifestyle Modification Programme to decrease dementia risk exposure in a primary care setting

INTRODUCTION

It has been estimated that a 10%-25% reduction in seven key risk factors could potentially prevent 1.1-3.0 million Alzheimer's disease cases globally. In addition, as dementia is preceded by more subtle cognitive deficits which have substantial social and economic impact, effective preventative interventions would likely have more extensive benefits. The current study evaluates in primary care a multidomain risk-reduction intervention targeting adults with high risk of developing dementia.

METHODS AND ANALYSIS

A randomised controlled trial (RCT) is being conducted to evaluate three intervention programmes using a pragmatic approach suitable to the clinic: (1) a 12-week online and face-to-face dementia risk-reduction intervention (Body Brain Life-General Practice (BBL-GP)); (2) a 6-week face-to-face group lifestyle modification programme (LMP); and (3) a 12-week email-only programme providing general health information. We aim to recruit 240 participants, aged 18 and over, to undergo a comprehensive cognitive and physical assessment at baseline and follow-ups (postintervention, 18, 36 and 62 weeks). The primary outcome is dementia risk measured with the modified version of the Australian National University-Alzheimer's Disease Risk Index Short Form. Secondary outcomes are cognitive function measured with Trails A and B, and the Digit Symbol Modalities Test; physical activity with moderate-vigorous physical activity and the International Physical Activity Questionnaire; depression with the Centre for Epidemiological Studies Depression; cost evaluation with the 12-item Short Form Health Survey, Framingham Coronary Heart Disease Risk Score and Australian Type 2 Diabetes Risk Assessment Tool; diet quality with the Australian Recommended Food Score; and sleep quality with the Pittsburgh Sleep Quality Index.

ETHICS AND DISSEMINATION

This RCT is a novel pragmatic intervention applied in a primary care setting to reduce the dementia risk exposure in adults at high risk. If successful, BBL-GP and LMP will provide a versatile, evidence-based package that can be easily and quickly rolled out to other primary care settings and which can be scaled up at relatively low cost compared with other strategies involving intensive interventions.

Australian general practitioners' perspective on the role of the workplace Return-to-Work Coordinator

General practitioners (GPs) play a key role in the return-to-work process, and yet their experiences working with workplace Return-to-Work Coordinators (RTWCs) have rarely been studied. The aim of this paper is to provide insights from the GP perspective about their experiences with workplace RTWCs and their preparedness for the role. GPs from Australian states and territories where legislation mandates workplaces employ a RTWC were requested to complete a questionnaire on their experiences with workplace RTWCs. Fifty GPs completed a questionnaire on the preparedness of RTWCs in relation to their role, with 58% (n=29) indicating RTWCs require more training. A total of 78% (n=39) of respondents considered RTWCs were important in assisting injured workers return to work, with 98% (n=49) ranking trustworthiness, respectfulness and ethicalness as the most important or an important trait for a RTWC to possess. Interestingly, 40% (n=20) of respondents themselves reported having no training in the return-to-work process. GPs acknowledge the importance of the workplace RTWC in the return-to-work process, and the results highlight the need for RTWCs to possess specific traits and undergo appropriate training for the facilitation of a successful return to work for injured workers.

Development of a discussion tool to enable well-being by providing choices for people with dementia: a qualitative study incorporating codesign and participatory action research

OBJECTIVE

To codesign a discussion tool to facilitate negotiation of risk between health professionals, people with dementia and carers.

METHODS

A qualitative approach using codesign. Thematic analysis was used to analyse interviews and focus groups with people with dementia, carers, healthcare staff and healthy older people exploring the issue of risk in dementia, the acceptability and development of a discussion tool.

RESULTS

Sixty-one participants identified the breadth, depth and complexity of risk in dementia care and the need for individualised solutions. They also deemed a discussion tool to facilitate negotiation of risk was acceptable and responses informed the tool development. Twenty-two participants provided feedback that was used to refine the final version.

CONCLUSION

Our discussion tool enables choices for people with dementia by focusing on abilities rather than deficits and assists health professionals to deliver person-centred care. Flash cards prompt concerns and the tool provides a range of strategies to address these issues.

An evaluation of discharge documentation for people with dementia discharged home from hospital – A cross-sectional pilot study

This study evaluated discharge documentation for people with dementia who were discharged home, against expected discharge criteria and determined relationships between compliance scores and outcomes. This cross-sectional study audited discharge documentation and conducted a post discharge survey of carers. There were 73 eligible discharges and clinically significant documentation deficits for people with dementia included: risk assessments of confusion (48%), falls and pressure injury (56%); provision of medication dose-decision aids (53%), provision of contact information for patient support groups (6%) and advance care planning (9%). There was no significant relationship between compliance scores and outcomes. Carer strain was reported to be high for many carers. People with dementia and their carers are more vulnerable and at higher risk of poor outcomes after discharge. There are opportunities for improved provision of medications and risk assessment for people with dementia, provision of information for patient support groups and advanced care planning.

Effects of facilitated family case conferencing for advanced dementia: A cluster randomised clinical trial

Background

Palliative care planning for nursing home residents with advanced dementia is often suboptimal. This study compared effects of facilitated case conferencing (FCC) with usual care (UC) on end-of-life care.

Methods

A two arm parallel cluster randomised controlled trial was conducted. The sample included people with advanced dementia from 20 Australian nursing homes and their families and professional caregivers. In each intervention nursing home (n = 10), Palliative Care Planning Coordinators (PCPCs) facilitated family case conferences and trained staff in person-centred palliative care for 16 hours per week over 18 months. The primary outcome was family-rated quality of end-of-life care (End-of-Life Dementia [EOLD] Scales). Secondary outcomes included nurse-rated EOLD scales, resident quality of life (Quality of Life in Late-stage Dementia [QUALID]) and quality of care over the last month of life (pharmacological/non-pharmacological palliative strategies, hospitalization or inappropriate interventions).

Results

Two-hundred-eighty-six people with advanced dementia took part but only 131 died (64 in UC and 67 in FCC which was fewer than anticipated), rendering the primary analysis under-powered with no group effect seen in EOLD scales. Significant differences in pharmacological (P < 0.01) and non-pharmacological (P < 0.05) palliative management in last month of life were seen. Intercurrent illness was associated with lower family-rated EOLD Satisfaction with Care (coefficient 2.97, P < 0.05) and lower staff-rated EOLD Comfort Assessment with Dying (coefficient 4.37, P < 0.01). Per protocol analyses showed positive relationships between EOLD and staff hours to bed ratios, proportion of residents with dementia and staff attitudes.

Conclusion

FCC facilitates a palliative approach to care. Future trials of case conferencing should consider outcomes and processes regarding decision making and planning for anticipated events and acute illness.

Integrated solutions for sustainable fall prevention in primary care, the iSOLVE project: a type 2 hybrid effectiveness-implementation design

Background

Despite strong evidence giving guidance for effective fall prevention interventions in community-residing older people, there is currently no clear model for engaging general medical practitioners in fall prevention and routine use of allied health professionals in fall prevention has been slow, limiting widespread dissemination. This protocol paper outlines an implementation-effectiveness study of the Integrated Solutions for Sustainable Fall Prevention (iSOLVE) intervention which has developed integrated processes and pathways to identify older people at risk of falls and engage a whole of primary care approach to fall prevention.

Methods/design

This protocol paper presents the iSOLVE implementation processes and change strategies and outlines the study design of a blended type 2 hybrid design. The study consists of a two-arm cluster randomized controlled trial in 28 general practices and recruiting 560 patients in Sydney, Australia, to evaluate effectiveness of the iSOLVE intervention in changing general practitioner fall management practices and reducing patient falls and the cost effectiveness from a healthcare funder perspective. Secondary outcomes include change in medications known to increase fall risk. We will simultaneously conduct a multi-methodology evaluation to investigate the workability and utility of the implementation intervention. The implementation evaluation includes in-depth interviews and surveys with general practitioners and allied health professionals to explore acceptability and uptake of the intervention, the coherence of the proposed changes for those in the work setting, and how to facilitate the collective action needed to implement changes in practice; social network mapping will explore professional relationships and influences on referral patterns; and, a survey of GPs in the geographical intervention zone will test diffusion of evidence-based fall prevention practices. The project works in partnership with a primary care health network, state fall prevention leaders, and a community of practice of fall prevention advocates.

Discussion

The design is aimed at providing clear direction for sustainability and informing decisions about generalization of the iSOLVE intervention processes and change strategies. While challenges exist in hybrid designs, there is a potential for significant outcomes as the iSOLVE pathways project brings together practice and research to collectively solve a major national problem with implications for policy service delivery.

Evidence-based occupational therapy for people with dementia and their families: What clinical practice guidelines tell us and implications for practice

BACKGROUND/AIM

The first evidence-based Clinical Practice Guidelines and Principles of Care for People with Dementia in Australia have been released. The Guidelines detail a number of important evidence-based recommendations for occupational therapists. The aim of this paper is (1) to provide an overview of Guideline development, and (2) to describe the evidence supporting a recommendation for occupational therapy. Common characteristics of effective occupational therapy programmes for people with dementia are described.

METHODS

Guideline development involved adaptation of existing high-quality guidelines developed overseas and 17 systematic reviews to ensure that the most recent high-quality evidence was included. One of the systematic reviews involved examining the evidence for interventions to promote independence in people with dementia. Specifically, we looked at the evidence for occupational therapy and its effect on activities of daily living, quality of life and carer impact.

RESULTS

A total of 109 recommendations are included in the Guidelines. Occupational therapy was found to significantly increase independence in activities of daily living and improve quality of life. Effective occupational therapy programmes involve: environmental assessment, problem solving strategies, carer education and interactive carer skills training.

CONCLUSION

Occupational therapists working with people with dementia in community settings should ensure that their time is spent on those aspects of intervention that are shown to be effective.

Thermoelastic modelling of the skin at finite deformations

The modelling and computation of the coupled thermal and mechanical response of human skin at finite deformations is considered. The model extends current thermal models to account for thermally- and mechanically-induced deformations. Details of the solution of the highly nonlinear system of governing equations using the finite element method are presented. A representative numerical example illustrates the importance of considering the coupled response for the problem of a rigid, hot indenter in contact with the skin.

Anticholinergic medicines in an older primary care population: a cross-sectional analysis of medicines' levels of anticholinergic activity and clinical indications

WHAT IS KNOWN AND OBJECTIVES

Adverse clinical outcomes have been associated with cumulative anticholinergic burden (to which low-potency as well as high-potency anticholinergic medicines contribute). The clinical indications for which anticholinergic medicines are prescribed (and thus the 'phenotype' of patients with anticholinergic burden) have not been established. We sought to establish the overall prevalence of prescribing of anticholinergic medicines, the prevalence of prescribing of low-, medium- and high-potency anticholinergic medicines, and the clinical indications for which the medicines were prescribed in an older primary care population.

METHODS

This was a cross-sectional analysis of a cohort study of Australian early-career general practitioners' (GPs') clinical consultations - the Registrar Clinical Encounters in Training (ReCEnT) study. In ReCEnT, GPs collect detailed data (including medicines prescribed and their clinical indication) for 60 consecutive patients, on up to three occasions 6 months apart. Anticholinergic medicines were categorized as levels 1 (low-potency) to 3 (high-potency) using the Anticholinergic Drug Scale (ADS).

RESULTS

During 2010-2014, 879 early-career GPs (across five of Australia's six states) conducted 20 555 consultations with patients aged 65 years or older, representing 35 506 problems/diagnoses. Anticholinergic medicines were prescribed in 10·4% [95% CIs 9·5-10·5] of consultations. Of the total anticholinergic load of prescribed medicines ('community anticholinergic load') 72·7% [95% CIs 71·0-74·3] was contributed by Level 1 medicines, 0·8% [95% CIs 0·5-1·3] by Level 2 medicines and 26·5% [95% CIs 24·8-28·1] by Level 3 medicines. Cardiac (40·0%), Musculoskeletal (16·9%) and Respiratory (10·6%) were the most common indications associated with Level 1 anticholinergic prescription. For Level 2 and 3 medicines (combined data), Psychological (16·1%), Neurological (16·1%), Musculoskeletal (15·7%) and Urological (11·1%) indications were most common.

WHAT IS NEW AND CONCLUSION

Anticholinergic medicines are frequently prescribed in Australian general practice, and the majority of the 'community' anticholinergic burden is contributed by 'low'-anticholinergic potency medicines whose anticholinergic effects may be largely 'invisible' to prescribing GPs. Furthermore, the clinical 'phenotype' of the patient with high anticholinergic burden may be very different to common stereotypes (patients with urological, psychological or neurological problems), potentially making recognition of risk of anticholinergic adverse effects additionally problematic for GPs.

Attitudes to Alzheimer's disease testing of Australian general practice patients: a cross-sectional questionnaire-based study

OBJECTIVE

In view of proposed screening for presymptomatic Alzheimer's disease (AD) with advanced imaging, and blood and cerebral spinal fluid analysis, we aimed to establish levels, and associations, of acceptance of AD testing modalities by general practice patients.

METHODS

A cross-sectional questionnaire-based study of consecutive patients (aged 50 years and over) of general practices of an Australian practice-based research network was used. The questionnaire elicited demographic data and attitudes to screening for other diseases and included the screening acceptance domain of the Perceptions Regarding Investigational Screening for Memory in Primary Care (PRISM-PC) instrument. This assesses receptivity to modalities of testing for AD: short questionnaire, blood test, cerebral imaging, and annual physician examination. Reflecting speculation of possible future AD diagnostic methods, an item regarding testing cerebral spinal fluid was also included. Associations of PRISM-PC scores were analyzed with multiple linear regression.

RESULTS

Of 489 participants (response rate 87%), 66.2% would like to know if they had AD. Participants were more accepting of testing modalities that were noninvasive or familiar (questionnaire, physician's examination, and blood test) as opposed to cerebral imaging or lumbar puncture. Attitudes to AD testing are influenced by a positive attitude to disease screening in general. Patients with a self-perceived higher risk of AD were less accepting of testing, as were participants with an educational level of junior high school (10 school years) or less.

CONCLUSIONS

This study demonstrates that a majority of patients would like to know if they have AD. Acceptability of testing modalities, however, varies. Noninvasive, familiar methods are more acceptable.
