Associations between unmet needs for daytime activities and company and scores on the Neuropsychiatric Inventory-Questionnaire in people with dementia: a longitudinal study.

OBJECTIVES: To examine prospectively the association between unmet needs for daytime activities and company and behavioural and psychological symptoms of dementia. METHODS: We included 451 people with mild or moderate dementia, from eight European countries, who were assessed three times over 12 months. Unmet needs were measured with the Camberwell Assessment of Need for the Elderly. Three sub-syndromes of the Neuropsychiatric Inventory-Questionnaire were regressed, one-by-one, against unmet needs for daytime activities and company, adjusting for demographic and clinical-functional covariates. RESULTS: Unmet needs for daytime activities were associated with more affective symptoms at baseline, six and twelve months, mean 0.74 (p < 0.001), 0.76 (p < 0.001) and 0.78 (p = 0.001) points higher score respectively, and with more psychotic symptoms at baseline (mean 0.39 points, p = 0.007) and at six months follow-up (mean 0.31 points, p = 0.006). Unmet needs for company were associated with more affective symptoms at baseline, six and twelve months, mean 0.44 (p = 0.033), 0.67 (p < 0.001) and 0.91 (p < 0.001) points higher score respectively, and with more psychotic symptoms at baseline (mean 0.40 points, p = 0.005) and at six months (mean 0.35 points, p = 0.002) follow-up. CONCLUSION: Interventions to reduce unmet needs for daytime activities and company could reduce affective and psychotic symptoms in people with dementia.

Do caregiver profiles predict the use of dementia care services? Findings from the Actifcare study.

Objectives: Previously developed dementia caregiver profiles defined by caregiver age and burden, have been associated with caregiver quality of life, depression and perseverance time. The current aim was to investigate whether these caregiver profiles could predict subsequent service use. In addition, non-personal (e.g. meals on wheels) and supportive services (e.g. Alzheimer café) in early dementia were investigated as predictors.Methods: A total of 451 dyads of people with dementia and their informal caregivers from eight European countries were followed for one year. People were included if they did not use formal (personal) care but were expected to do so within 1 year. Logistic regression analyses were used with four clusters of service use as dependent variables (home social care, home personal care, day care and admission). The independent variables were caregiver profiles, and non-personal and supportive services at baseline.Results: Caregiver profiles were significant predictors of service use; those experiencing high strain were more likely to use formal care. The use of low-intensity, less intrusive services at baseline significantly predicted the use of home personal care and admission at follow-up. The use of day care at follow-up was predicted by the baseline use of supportive services.Conclusion: Caregiver profiles are valuable predictors for service use: this knowledge can aid professionals in ensuring optimal access to services, which is important for maintaining independence at home. In addition, the use of supportive and less intrusive, non-personal services in the early stages of dementia is to be advised.

Is there equity in initial access to formal dementia care in Europe? The Andersen Model applied to the Actifcare cohort.

OBJECTIVES: In the current study, the Anderson model is used to determine equitable access to dementia care in Europe. Predisposing, enabling, and need variables were investigated to find out whether there is equitable access to dementia-specific formal care services. Results can identify which specific factors should be a target to improve access. METHODS: A total of 451 People with middle-stage dementia and their informal carers from eight European countries were included. At baseline, there was no use of formal care yet, but people were expected to start using formal care within the next year. Logistic regressions were carried out with one of four clusters of service use as dependent variables (home social care, home personal care, day care, admission). The independent variables (predisposing, enabling, and need variables) were added to the regression in blocks. RESULTS: The most significant predictors for the different care clusters are disease severity, a higher sum of (un)met needs, hours spent on informal care, living alone, age, region of residence, and gender. CONCLUSION: The Andersen model provided for this cohort the insight that (besides need factors) the predisposing variables region of residence, gender, and age do play a role in finding access to care. In addition, it showed us that the numbers of hours spent on informal care, living alone, needs, and disease severity are also important predictors within the model's framework. Health care professionals should pay attention to these predisposing factors to ensure that they do not become barriers for those in need for care.

Optimizing access to and use of formal dementia care: Qualitative findings from the European Actifcare study.

This paper reports on qualitative data from the Actifcare study investigating experiences, attitudes, barriers and facilitators concerning access to and use of formal care. A total of 85 semi-structured in-depth interviews were conducted in eight European countries. Results were analysed with a deductive content analysis, first within country and then integrated in a cross-national analysis. Overall, analysis of the in-depth interviews revealed two major themes with five subcategories. The results can be summarised in an optimal pathway for access to dementia care. This pathway includes fixed factors such as disease-related factors and system-related factors. In addition there are personal factors that are subject to change such as attitudes towards care. An important finding consisted of the necessity of having sufficient information about the disease and available care and having a key contact person to guide you through the process of finding suitable care while monitoring your needs. In addition, it is important to involve your social network as they can take on care-giving tasks. It is helpful to have a diagnosis (in most countries). Concerning decision-making, the person closest to the person with dementia is in the majority of cases the one who makes the ultimate decision to access and use services and he/she should therefore be supported in this process. These results provide insight into the factors that influence the pathway to formal care use and help professionals to enhance access to formal dementia care by focusing on factors that can be modified.

Impact of Untimely Access to Formal Care on Costs and Quality of Life in Community Dwelling People with Dementia.

BACKGROUND: Access to formal care is not always timely and a better understanding on the impact of untimely access is needed. OBJECTIVE: To examine, from a societal perspective, the impact of untimely access to formal care in terms of total costs and quality of life over one year in community dwelling people with dementia. METHODS: Within the Actifcare study, needs, resource use, and quality of life were observed for one year in a cohort of 451 community dwelling people with dementia in 8 European countries. Untimely access to care was operationalized as having at least one unmet need for care identified by the Camberwell Assessment of Need for the Elderly (CANE) instrument. Two regression models were built for both total costs and quality of life measured by the EQ-5D-5L, one using sum of unmet needs and one using a predefined selection of need items. RESULTS: Unmet needs were not associated with higher total costs but they were associated with a lower quality of life of people with dementia. Of all CANE items, only an unmet need for "company" was significantly related to lower total costs. CONCLUSION: Total costs did not seem to differ between participants with unmet and met needs. Only few associations between specific unmet needs and costs and quality of life were found. Furthermore, quality of life of people with dementia decreases when multiple unmet needs are experienced, indicating that assessing and meeting needs is important to improve quality of life.

Quality of Life, Care Resource Use, and Costs of Dementia in 8 European Countries in a Cross-Sectional Cohort of the Actifcare Study.

BACKGROUND: With 10.5 million people with dementia in Europe and $301 billion associated costs, governments face challenges organizing access to care. OBJECTIVE: To examine the costs related to formal and informal care use and quality of life for people with dementia in eight European countries, and explore the association with unmet needs. METHODS: Cross-sectional data from 451 persons with dementia and their informal caregivers of the Actifcare cohort study were obtained. Formal and informal care use was multiplied by country specific unit prices of services. Needs were measured using the CANE and health-related quality of life (HRQOL) of the person with dementia (both self- and proxy-rated) and informal caregiver's quality of life using EQ-5D-5L, ICECAP-O, DEMQOL-U, and CarerQol utility scores. The association between costs and country, European region, and unmet needs was assessed using multi-level linear regression. RESULTS: Self-rated EQ-5D-5L utility score was higher than proxy-rated (0.84 and 0.71, respectively). Informal caregivers' utility score was 0.84. Across eight countries annual mean costs of formal and informal care were approximately € 17,000. Unmet needs were not associated with annual costs of care, nor with proxy-rated HRQOL, but were associated with self-rated HRQOL. CONCLUSION: We found varying relationships between unmet needs and quality of life, and no association between unmet needs and care costs, although the results were sensitive to various factors. Future research should further investigate the relation between unmet needs, quality of life and costs to generate a better understanding of the effects of (un)timely access to care.

Needs and quality of life of people with middle-stage dementia and their family carers from the European Actifcare study. When informal care alone may not suffice.

OBJECTIVE: The Actifcare (Access to timely formal care) study investigated needs of people with dementia and their families during the phase in which formal care is being considered, and examined whether higher need levels are related to lower quality of life (QOL). METHOD: From eight European countries 451 people with dementia and their carers participated. Needs were measured with the Camberwell Assessment of Need for the Elderly. QOL was measured with the QOL-AD, and carer quality of life was measured with the CarerQol. The relationship between needs and QOL was analysed with multiple regression analyses. RESULTS: Needs were expressed in the domains of psychological distress, daytime activities, company and information. People with dementia rated their unmet needs significantly lower than their carers: the mean number of self-rated unmet needs was 0.95, whereas the mean proxy ratings were 1.66. For met needs, the self-rated mean was 5.5 and was 8 when proxy-rated. The level of needs reported was negatively associated with QOL for both. CONCLUSION: The study results show that informal carers reported almost twice as many needs as people with dementia. The domains in which needs are expressed should be the primary focus for interventions to support   QOL. The perspectives of people with dementia are informative when identifying needs.

Perspectives of policy and political decision makers on access to formal dementia care: expert interviews in eight European countries.

BACKGROUND: As part of the ActifCare (ACcess to Timely Formal Care) project, we conducted expert interviews in eight European countries with policy and political decision makers, or representatives of relevant institutions, to determine their perspectives on access to formal care for people with dementia and their carers. METHODS: Each ActifCare country (Germany, Ireland, Italy, The Netherlands, Norway, Portugal, Sweden, United Kingdom) conducted semi-structured interviews with 4-7 experts (total N = 38). The interview guide addressed the topics "Complexity and Continuity of Care", "Formal Services", and "Public Awareness". Country-specific analysis of interview transcripts used an inductive qualitative content analysis. Cross-national synthesis focused on similarities in themes across the ActifCare countries. RESULTS: The analysis revealed ten common themes and two additional sub-themes across countries. Among others, the experts highlighted the need for a coordinating role and the necessity of information to address issues of complexity and continuity of care, demanded person-centred, tailored, and multidisciplinary formal services, and referred to education, mass media and campaigns as means to raise public awareness. CONCLUSIONS: Policy and political decision makers appear well acquainted with current discussions among both researchers and practitioners of possible approaches to improve access to dementia care. Experts described pragmatic, realistic strategies to influence dementia care. Suggested innovations concerned how to achieve improved dementia care, rather than transforming the nature of the services provided. Knowledge gained in these expert interviews may be useful to national decision makers when they consider reshaping the organisation of dementia care, and may thus help to develop best-practice strategies and recommendations.

The Diagnostic and Prognostic Value of Neuropsychological Assessment in Memory Clinic Patients.

BACKGROUND: Neuropsychological testing has long been embedded in daily clinical practice at memory clinics but the added value of a complete neuropsychological assessment (NPA) to standard clinical evaluation is unknown. OBJECTIVE: To evaluate the added diagnostic and prognostic value of NPA to clinical evaluation only in memory clinic patients. METHODS: In 221 memory clinic patients of a prospective cohort study, clinical experts diagnosed clinical syndrome (subjective cognitive impairment (SCI), mild cognitive impairment (MCI), or dementia) and etiology (Alzheimer's disease (AD) or no AD), and provided a prognosis of disease course (decline or no decline) before and after results of NPA were made available. The reference standard was a panel consensus based on all clinical information at baseline and up to 2 follow-up assessments. RESULTS: With NPA data available, clinicians changed their initial syndromal diagnosis in 22% of patients, and the etiological diagnosis as well as the prognosis in 15%. This led to an increase in correctly classified cases of 18% for syndromal diagnosis, 5% for etiological diagnosis, and 1% for prognosis. NPA data resulted in the largest improvement in patients initially classified as SCI (syndrome: 93.3% (n = 14) correctly reclassified, etiology: net reclassification improvement [NRI] = 0.61, prognosis: NRI = 0.13) or MCI (syndrome: 89.3% (n = 23) correctly reclassified, etiology: NRI = 0.17, prognosis: NRI = 0.14), while there was no improvement in patients with dementia (syndrome: 100% (n = 1) correctly reclassified, etiology: NRI = -0.05, prognosis: NRI = -0.06). Overall, inclusion of NPA in the diagnostic process increased confidence in all diagnoses with 6-7%. CONCLUSION: Administration of a complete NPA after standard clinical evaluation has added value for diagnosing cognitive syndrome and its underlying etiology in patients regarded as non-demented based on the first clinical impression.

Access to timely formal dementia care in Europe: protocol of the Actifcare (ACcess to Timely Formal Care) study.

BACKGROUND: Previous findings indicate that people with dementia and their informal carers experience difficulties accessing and using formal care services due to a mismatch between needs and service use. This mismatch causes overall dissatisfaction and is a waste of the scarce financial care resources. This article presents the background and methods of the Actifcare (ACcess to Timely Formal Care) project. This is a European study aiming at best-practice development in finding timely access to formal care for community-dwelling people with dementia and their informal carers. There are five main objectives: 1) Explore predisposing and enabling factors associated with the use of formal care, 2) Explore the association between the use of formal care, needs and quality of life and 3) Compare these across European countries, 4) Understand the costs and consequences of formal care services utilization in people with unmet needs, 5) Determine the major costs and quality of life drivers and their relationship with formal care services across European countries. METHODS: In a longitudinal cohort study conducted in eight European countries approximately 450 people with dementia and informal carers will be assessed three times in 1 year (baseline, 6 and 12 months). In this year we will closely monitor the process of finding access to formal care. Data on service use, quality of life and needs will be collected. DISCUSSION: The results of Actifcare are expected to reveal best-practices in organizing formal care. Knowledge about enabling and predisposing factors regarding access to care services, as well as its costs and consequences, can advance the state of the art in health systems research into pathways to dementia care, in order to benefit people with dementia and their informal carers.

Early cost-utility analysis of general and cerebrospinal fluid-specific Alzheimer's disease biomarkers for hypothetical disease-modifying treatment decision in mild cognitive impairment.

INTRODUCTION: The study aimed to determine the room for improvement of a perfect cerebrospinal fluid (CSF) biomarker and the societal incremental net monetary benefit of CSF in subjects with mild cognitive impairment (MCI) assuming a hypothetical disease-modifying Alzheimer's disease (AD) treatment. METHODS: A decision model compared current practice to a perfect biomarker and to two strategies positioning CSF as add-on test when current practice concluded the presence or absence of AD. RESULTS: The simulated MCI population was aged on average 68.3 and 49% had AD. The room for improvement by the perfect CSF test was 0.39 quality adjusted life years, €33,622 ($43,372) savings, 2.0 potential beneficial treatment years, and 1.3-year delay in dementia conversion. DISCUSSION: The results indicated more potential benefit from a biomarker positioned to verify subjects who are not expected to have AD (i.e., to prevent undertreatment) rather than to verify subjects expected to have AD (prevent overtreatment). Sensitivity analyses explored different CSF positions.

Qualitative study on needs and wishes of early-stage dementia caregivers: the paradox between needing and accepting help.

BACKGROUND: Early individualized interventions for informal dementia caregivers can prevent overburdening in the later stages. However, the needs of early-stage dementia caregivers (EDC) remain largely unknown. This study aimed to explore the needs and wishes and need for care of EDC to maximize the benefit of potential programs for EDC and tailor interventions accordingly. METHODS: Four focus group interviews with 28 informal caregivers of people with dementia (PwD) were analyzed using inductive content analysis. Both EDC and caregivers in the later stages were included to compare perceived EDC needs from different points in the caregiver career. RESULTS: Four themes were identified: the early-stage needs paradox, barriers in acceptance, facilitators in acceptance, and a transition from loss to adaptation. The retrospective view provided by later-stage caregivers differed from the view of EDC; EDC struggled with acknowledging needs due to fear of stigma and low acceptance. EDC stressed the importance of acceptance as a prerequisite for adequate adaptation, but were hindered by lack of knowledge, difficulty acknowledging changes, and focus on loss. In contrast, better understanding of the disease, increasing personal time, structuring ones day, and using appropriate humor can reduce negative communication, increase positive encounters and caregiver-confidence, contributing to positive interaction with the care recipient and an increase in well-being. CONCLUSIONS: Early therapeutic interventions could help caregivers identify their needs, increase knowledge about changes in roles and relationship reciprocity, and focus on enhancement of the positive, intact experiences to prevent caregiver burden.

Diagnosing Alzheimer's disease: a systematic review of economic evaluations.

BACKGROUND: The objective of this study is to systematically review the literature on economic evaluations of interventions for the early diagnosis of Alzheimer's disease (AD) and related disorders and to describe their general and methodological characteristics. We focused on the diagnostic aspects of the decision models to assess the applicability of existing decision models for the evaluation of the recently revised diagnostic research criteria for AD. METHODS: PubMed and the National Institute for Health Research Economic Evaluation database were searched for English-language publications related to economic evaluations on diagnostic technologies. Trial-based economic evaluations were assessed using the Consensus on Health Economic Criteria list. Modeling studies were assessed using the framework for quality assessment of decision-analytic models. RESULTS: The search retrieved 2109 items, from which eight decision-analytic modeling studies and one trial-based economic evaluation met all eligibility criteria. CONCLUSIONS: Diversity among the study objective and characteristics was considerable and, despite considerable methodological quality, several flaws were indicated. Recommendations were focused on diagnostic aspects and the applicability of existing models for the evaluation of recently revised diagnostic research criteria for AD.

Cost-effectiveness of one year dementia follow-up care by memory clinics or general practitioners: economic evaluation of a randomised controlled trial.

OBJECTIVE: To evaluate the cost-effectiveness of post-diagnosis dementia treatment and coordination of care by memory clinics compared to general practitioners' care. METHODS: A multicentre randomised trial with 175 community dwelling patients newly diagnosed with mild to moderate dementia, and their informal caregivers, with twelve months' follow-up. Cost-effectiveness was evaluated from a societal point of view and presented as incremental cost per quality adjusted life year. To establish cost-effectiveness, a cost-utility analysis was conducted using utilities based on the EQ-5D. Uncertainty surrounding the incremental cost-effectiveness ratio (difference in costs divided by difference in effects) was calculated by bootstrapping from the original data. RESULTS: Compared to general practitioners' care, treatment by the memory clinics was on average €1024 (95% CI: -€7723 to €5674) cheaper, and showed a non-significant decrease of 0.025 (95% CI: -0.114 to 0.064) quality adjusted life years. The incremental cost-effectiveness point estimate from the bootstrap simulation was € 41 442 per QALY lost if one would use memory clinic care instead of general practitioner care. CONCLUSION: No evidence was found that memory clinics were more cost-effective compared to general practitioners with regard to post-diagnosis treatment and coordination of care of patients with dementia in the first year after diagnosis. TRIAL REGISTRATION: ClinicalTrials.gov NCT00554047.

Determinants of care costs of patients with dementia or cognitive impairment.

INTRODUCTION: Dementia causes a high burden on patients, caregivers, and societies. Decision analytic models to support allocation of resources are often developed making use of cost-of-illness (COI) studies. However, current COI study estimates are highly variable due to care setting and methodological issues. We aim to explore variables explaining the variation of (formal and informal) health care costs of cognitive disorders, using a broad spectrum of variables, including patient, caregiver, and social context variables. METHODS: A bottom-up COI study design was used in which a societal viewpoint and a validated method to measure and value informal care was applied. Data were analyzed using univariate, multivariate, and forward regression analyses. RESULTS: The average 1-year health care sector costs were &OV0556;26,140 ($34,505 or £17,775) and &OV0556;11,931 ($15,749 or £8113) for patient and family. The analyses indicated that cognitive functioning, caregiver burden, patient sex, and instrumental activities of daily living were significantly associated with care costs independently. CONCLUSIONS: Cognitive functioning and instrumental activities of daily living are important variables to include in health care decision models. We recommend also including caregiver burden and patient sex in decision models for health policy decision makers to fully reflect the heterogeneity of the disease progression of cognitive disorders.

Diagnostic and economic evaluation of new biomarkers for Alzheimer's disease: the research protocol of a prospective cohort study.

BACKGROUND: New research criteria for the diagnosis of Alzheimer's disease (AD) have recently been developed to enable an early diagnosis of AD pathophysiology by relying on emerging biomarkers. To enable efficient allocation of health care resources, evidence is needed to support decision makers on the adoption of emerging biomarkers in clinical practice. The research goals are to 1) assess the diagnostic test accuracy of current clinical diagnostic work-up and emerging biomarkers in MRI, PET and CSF, 2) perform a cost-consequence analysis and 3) assess long-term cost-effectiveness by an economic model. METHODS/DESIGN: In a cohort design 241 consecutive patients suspected of having a primary neurodegenerative disease are approached in four academic memory clinics and followed for two years. Clinical data and data on quality of life, costs and emerging biomarkers are gathered.Diagnostic test accuracy is determined by relating the clinical practice and new research criteria diagnoses to a reference diagnosis. The clinical practice diagnosis at baseline is reflected by a consensus procedure among experts using clinical information only (no biomarkers). The diagnosis based on the new research criteria is reflected by decision rules that combine clinical and biomarker information. The reference diagnosis is determined by a consensus procedure among experts based on clinical information on the course of symptoms over a two-year time period.A decision analytic model is built combining available evidence from different resources among which (accuracy) results from the study, literature and expert opinion to assess long-term cost-effectiveness of the emerging biomarkers. DISCUSSION: Several other multi-centre trials study the relative value of new biomarkers for early evaluation of AD and related disorders. The uniqueness of this study is the assessment of resource utilization and quality of life to enable an economic evaluation. The study results are generalizable to a population of patients who are referred to a memory clinic due to their memory problems. TRIAL REGISTRATION: NCT01450891.

Effectiveness of dementia follow-up care by memory clinics or general practitioners: randomised controlled trial.

OBJECTIVE: To examine the effectiveness of post-diagnosis dementia treatment and coordination of care by memory clinics compared with general practitioners. DESIGN: Multicentre randomised controlled trial. SETTING: Nine memory clinics and 159 general practitioners in the Netherlands. PARTICIPANTS: 175 patients with a new diagnosis of mild to moderate dementia living in the community and their informal caregivers. INTERVENTIONS: Usual care provided by memory clinic or general practitioner. MAIN OUTCOME MEASURES: Caregiver rated quality of life of the patient measured with the quality of life in Alzheimer's disease instrument and self perceived burden of the informal caregiver measured with the sense of competence questionnaire (intention to treat analysis). RESULTS: The quality of life of the patients in the memory clinic group was 0.5 (95% confidence interval -0.7 to 1.6) points higher than in the general practitioner group. Caregivers' burden was 2.4 (-5.8 to 1.0) points lower in the memory clinic group than in the general practitioner group. CONCLUSION: No evidence was found that memory clinics were more effective than general practitioners with regard to post-diagnosis treatment and coordination care for patients with dementia. Without further evidence on the effectiveness of these modalities, other arguments, such as cost minimisation, patients' preferences, or regional health service planning, can determine which type of dementia care is offered. TRIAL REGISTRATION: Clinical trials NCT00554047.

Predictive factors for the objective burden of informal care in people with dementia: a systematic review.

BACKGROUND: Informal care plays a substantial role in the provision of total care in dementia. Several reviews have been published on the predictive factors of subjective burden; however, such a review lacks information on objective burden, which refers to the amount and/or costs of informal care. OBJECTIVES: The objectives of this study were to (1) give an overview of the predictive factors that are associated with the objective burden of informal care; (2) discuss whether these factors are similar to the predictive factors of subjective burden; and (3) examine whether they are modifiable. DESIGN: The literature in a number of international databases was systematically searched. Methodological quality and level of certainty were assessed. RESULTS: Ten studies were identified as relevant for the purpose of this review, describing a total of 39 predictive factors. Three factors (behavioral problems and impairments regarding daily functioning and cognition) were considered to be predictors of objective burden. Three factors were not related; 12 were potential predictors; and the results of the remaining 22 factors were inconclusive. CONCLUSIONS: Many factors were found to be (potential) predictors of objective burden, reflecting its complex nature. Objective and subjective burdens are 2 different relevant aspects of informal care. Interventions aimed at countering behavioral problems and impairments regarding daily functioning could reduce objective burden.

Empowered or overpowered? Service use, needs, wants and demands in elderly patients with cognitive impairments.

BACKGROUND: Examination of clinical practice reveals that current treatment options are often not sufficiently utilized by patients suffering from dementia or mild cognitive impairment. OBJECTIVE: This study aimed to investigate to what extent and in what way these patients utilize the available treatment options, as well as to identify factors and reasons that play a role in the non-utilization of these options. METHODS: Semi-structured interviews by telephone were held with the patients' caregivers. RESULTS: Counseling, medication, activities and home care were the options that were most frequently utilized by the 252 patients and caregivers who were included in the study. Group guidance and admissions were the main treatment categories that had not been utilized (although they were proposed). The most important reasons given were refusal by the patient and the fact that help was not necessary yet according to the caregiver. Burden of care and cognition were the most important factors in predicting which of the treatment options were not utilized. CONCLUSIONS: Most patients and caregivers are not aware of the treatment options available to them. Awareness of these options is necessary to avoid situations in which patients and caregivers find themselves with their backs against the wall and the need for care support has become an acute necessity. Health care professionals should play an important role with regard to this empowerment.

Economic evaluation of an integrated diagnostic approach for psychogeriatric patients: results of a randomized controlled trial.

CONTEXT: Because of the increasing number of elderly people with dementia, the costs of dementia and dementia care are expected to grow rapidly in the coming decades. Cost-effectiveness results are relevant for decision making about new strategies in dementia care. OBJECTIVE: To evaluate the cost-effectiveness of an integrated multidisciplinary diagnostic facility for diagnosing dementia in ambulatory psychogeriatric patients. DESIGN: Randomized controlled trial with an economic evaluation component. SETTING: The Maastricht Evaluation of a Diagnostic Intervention for Cognitively Impaired Elderly, Maastricht University Hospital, Maastricht, the Netherlands. PATIENTS: A total of 137 patients who received care in the multidisciplinary diagnostic facility and 93 who received usual care. MAIN OUTCOME MEASURES: Quality-adjusted life-years (QALYs) as the main outcome measure and cognition and behavioral problems as secondary outcome measures. RESULTS: Compared with patients receiving usual care, patients who visited the diagnostic facility gained a mean 0.05 QALY at the extra cost of euro65. The incremental cost per QALY amounted to euro1267. This point estimate lies beneath commonly accepted thresholds and is within an acceptable range of uncertainty. With regard to the secondary analyses, cost-effectiveness results showed a substantial amount of uncertainty and were therefore indecisive. CONCLUSION: On the basis of the main cost-per-QALY analysis, the use of the integrated multidisciplinary diagnostic facility is cost-effective for the diagnosis and management of dementia in ambulatory patients.
