Are community-living and institutionalized dementia patients cared for differently? Evidence on service utilization and costs of care from German insurance claims data

Bridging the Gap: A Comparative Analysis of Healthcare Quality Perceptions Between the Older People and Healthcare Providers

In our study aimed at improving the healthcare system for the aging population, we compared healthcare quality evaluations between 96 older individuals and 30 healthcare providers in Split-Dalmatia County (Croatia). Using nonparametric analyses such as the Mann-Whitney and Wilcoxon tests on Likert scale questionnaire scores, we found most participants highlighted challenges such as healthcare affordability, long wait times, reliance on private care, poor public transportation, and insufficient rural healthcare services. Healthcare providers rated these quality indicators even more negatively. Both groups rated healthcare for dementia patients notably lower, while emergency response, treatment quality, and hospitalization ease were generally rated positively. The heightened awareness among healthcare providers raises the question: why is there a significant delay between recognizing these problems and implementing effective solutions to address them?

Integrated palliative homecare in advanced dementia: reduced healthcare utilisation and costs

OBJECTIVES

To determine the economic benefit of an integrated home-based palliative care programme for advanced dementia (Programme Dignity), evaluation is required. This study aimed to estimate Programme Dignity's average monthly cost from a provider's perspective; and compare healthcare utilisation and costs of programme patients with controls, accounting for enrolment duration.

METHODS

This was a retrospective cohort study. Home-dwelling patients with advanced dementia (stage 7 on the functional assessment staging in Alzheimer's disease) with a history of pneumonia, albumin <35 g/L or tube-feeding and known to be deceased were analysed (Programme Dignity=184, controls=139). One-year programme operational costs were apportioned on a per patient-month basis. Cumulative healthcare utilisation and costs were examined at 1, 3 and 6 months look-back from death. Between-group comparisons used Poisson, zero-inflated Poisson regressions and generalised linear models.

RESULTS

The average monthly programme cost was SGD$1311 (SGD-Pounds exchange rate: 0.481) per patient. Fully enrolled programme patients were less likely to visit the emergency department (incidence rate ratios (IRRs): 1 month=0.56; 3 months=0.19; 6 months=0.10; all p<0.001), be admitted to hospital (IRRs: 1 month=0.60; 3 months=0.19; 6 months=0.15; all p<0.001), had a lower cumulative length of stay (IRRs: 1 month=0.78; 3 months=0.49; 6 months=0.24; all p<0.001) and incurred lesser healthcare utilisation costs (β-coefficients: 1 month=0.70; 3 months=0.40; 6 months=0.43; all p<0.01) at all time-points examined.

CONCLUSION

Programme Dignity for advanced dementia reduces healthcare utilisation and costs. If scalable, it may benefit more patients wishing to remain at home at the end-of-life, allowing for a potentially sustainable care model to cope with rapid population ageing. It contributes to the evidence base of advanced dementia palliative care and informs healthcare policy making. Future studies should estimate informal caregiving costs for comprehensive economic evaluation.

The Costs of Dementia in Europe: An Updated Review and Meta-analysis

BACKGROUND AND OBJECTIVE

The prevalence of dementia is increasing, while new opportunities for diagnosing, treating and possibly preventing Alzheimer's disease and other dementia disorders are placing focus on the need for accurate estimates of costs in dementia. Considerable methodological heterogeneity creates challenges for synthesising the existing literature. This study aimed to estimate the costs for persons with dementia in Europe, disaggregated into cost components and informative patient subgroups.

METHODS

We conducted an updated literature review searching PubMed, Embase and Web of Science for studies published from 2008 to July 2021 reporting empirically based cost estimates for persons with dementia in European countries. We excluded highly selective or otherwise biased reports, and used a random-effects meta-analysis to produce estimates of mean costs of care across five European regions.

RESULTS

Based on 113 studies from 17 European countries, the estimated mean costs for all patients by region were highest in the British Isles (73,712 EUR), followed by the Nordics (43,767 EUR), Southern (35,866 EUR), Western (38,249 EUR), and Eastern Europe and Baltics (7938 EUR). Costs increased with disease severity, and the distribution of costs over informal and formal care followed a North-South gradient with Southern Europe being most reliant on informal care.

CONCLUSIONS

To our knowledge, this study represents the most extensive meta-analysis of the cost for persons with dementia in Europe to date. Though there is considerable heterogeneity across studies, much of this is explained by identifiable factors. Further standardisation of methodology for capturing resource utilisation data may further improve comparability of future studies. The cost estimates presented here may be of value for cost-of-illness studies and economic evaluations of novel diagnostic technologies and therapies for Alzheimer's disease.

Toward mandatory health insurance in low-income countries? An analysis of claims data in Tanzania

Many low-income countries are in the process of scaling up health insurance with the goal of achieving universal coverage. However, little is known about the usage and financial sustainability of mandatory health insurance. This study analyzes 26 million claims submitted to the Tanzanian National Health Insurance Fund (NHIF), which covers two million public servants for whom public insurance is mandatory, to understand insurance usage patterns, cost drivers, and financial sustainability. We find that in 2016, half of policyholders used a health service within a single year, with an average annual cost of 33 US$ per policyholder. About 10% of the population was responsible for 80% of the health costs, and women, middle-age and middle-income groups had the highest costs. Out of 7390 health centers, only five health centers are responsible for 30% of total costs. Estimating the expected health expenditures for the entire population based on the NHIF cost structure, we find that for a sustainable national scale-up, policy makers will have to decide between reducing the health benefit package or increasing revenues. We also show that the cost structure of a mandatory insurance scheme in a low-income country differs substantially from high-income settings. Replication studies for other countries are warranted.

Individual and regional determinants of long-term care expenditure in Japan: evidence from national long-term care claims

BACKGROUND

Japan, with the oldest population in the world, faces a financial challenge caused by rising long-term care (LTC) expenditure. For policymakers to address this, it is important that we have a better understanding of how individual and regional characteristics affect LTC expenditure.

METHODS

We linked national LTC insurance (LTCI) claim data, covering the entire population who used LTCI services in Japan, with municipality data on an individual level. Individuals 65 years and older (n=3 876 068) who had used LTCI benefits at least once in the fiscal year (FY) 2016 were included. We examined the associations of individual and municipality characteristics regarding supply and demand of healthcare with the LTC expenditures on facility care, home and community care, and total care (the sum of both types of care), after adjusting for regional differences in LTC extra charges.

RESULTS

The following variables were associated with higher total expenditure; at the individual level: female, a higher care-need level, a lower income (0% co-payments) or a facility service user; at the municipality level: municipalities locating in metropolitan areas, with a higher proportion of single elderly households, more doctors per 1000 citizens, more nursing homes per 100 000 LTC benefit users or more outpatient medical spending per citizen ≥75 years old.

CONCLUSIONS

As we are able to identify several individual and municipality characteristics associated with higher LTC expenditure in Japan, the study offers insights into dealing with the rapidly growing LTC expenditure.

Improvement in the long-term care burden after surgical treatment of patients with idiopathic normal pressure hydrocephalus: a supplementary study

Idiopathic normal pressure hydrocephalus (iNPH) is a surgically treatable syndrome commonly observed in older adults. However, it is unclear whether clinical improvements after surgery can effectively reduce the long-term care burden (LTCB). In this study, we determined whether shunt surgery was effective in decreasing LTCB. We also investigated the degree of variability in patients and hospitals, using data from the iNPH multicenter study. This study involved 69 participants who underwent lumboperitoneal shunt surgery with follow-up for 12 months. A generalized linear mixed model was applied to analyze the fixed and random effects simultaneously. Regarding LTCB, the disability grades improved significantly. Although the dementia grades also improved, it was not statistically significant. The differences in the LTCB grades in most patients were within the range of the 95% confidence intervals, while in the case of hospitals, some were often out of the range. Further studies are needed to improve dementia in patients with iNPH. The incorporation of random variables, such as hospitals, is important for the analysis of data from multicenter studies.

Differences in Function and Healthcare Cost of Older Adults with Dementia by Long-Term Care Service Type: A National Dataset Analysis

This study aims to analyze the function and cost changes among long-term care insurance (LTCI) beneficiaries with low-severity dementia according to their LTCI service type. Data were collected from the Korean LTCI and national health insurance (NHI) datasets. Participants were 4414 beneficiaries with dementia aged 65 or older who received LTC services continuously for 4 years (2008–2011). LTCI service types were classified into home care (HC), institutional care (IC), and combined care (CC). Activities of daily living (ADL), cognitive function, medical cost, and benefit-cost were assessed. Linear mixed models and multiple regression models were used to analyze the changes in function and costs of the beneficiaries. ADL, cognitive function, medical cost, and benefit-cost differed significantly depending on the service type and time (p < 0.001). LTCI service types affected the degree of changes in ADL, cognitive function, medical cost, and benefit-cost over four years and showed negative changes in IC and CC beneficiaries than HC beneficiaries. HC is a cost-effective way to maintain the function of beneficiaries with low-severity dementia. Thus, efforts are needed to actively promote HC services.

Identifying the long-term care beneficiaries: differences between risk factors of nursing homes and community-based services admissions

BACKGROUND

The Portuguese long-term care sector is classified into home and community-based services (HCBS) and three nursing home (NH) units: convalescence, medium term and rehabilitation, and long term and maintenance.

AIMS

To identify the main factors of admission into each care setting and explore to what extent these populations are different. 14,140 patients from NH and 6844 from HCBS were included from all over the country.

METHODS

A logistic regression was estimated to identify determinants of admission into NH care, using sociodemographic characteristics, medical conditions and dependence levels at admission as independent variables, and region of care, referral entity and placement process as control variables. Then, ordered logistic regression was used to identify the contribution of the above factors in each specific NH unit.

RESULTS

Being female, not being married, not having family/neighbour support, being literate, having mental illness, being cognitively or physically impaired are the main predictors of being admitted into a NH. Within the NH units, placements of the large majority of patients were accurately predicted, based on the available variables. However, for around half of the patients referred to long-term care units, the model expected placements into medium-term units, while for those admitted into short-stay units, the model returned that 29% could have benefited from being admitted into a medium-term care unit.

DISCUSSION AND CONCLUSIONS

Patients' accurate placement is a highly complex and challenging process, demanding more variables than the ones available for the model here presented. Our work confirms the need to collect other type of variables to improve the placement decision process.

Cost-effectiveness of a non-pharmacological treatment vs. "care as usual" in day care centers for community-dwelling older people with cognitive impairment: results from the German randomized controlled DeTaMAKS-trial

BACKGROUND

Cognitive impairment in older adults causes a high economic and societal burden. This study assesses the cost-effectiveness of the multicomponent, non-pharmacological MAKS treatment vs. "care as usual" in German day care centers (DCCs) for community-dwelling people with mild cognitive impairment (MCI) or mild to moderate dementia over 6 months.

METHODS

The analysis was conducted from the societal perspective alongside the cluster-randomized controlled, multicenter, prospective DeTaMAKS-trial with waitlist group design. Outcomes were Mini-Mental Status Examination (MMSE) and Erlangen Test of Activities of Daily Living in Persons with Mild Dementia or Mild Cognitive Impairment (ETAM) of 433 individuals in 32 DCCs. Incremental differences in MMSE and ETAM were calculated via a Gaussian-distributed and incremental cost difference via a Gamma-distributed Generalized Linear Model. Cost-effectiveness was assessed via cost-effectiveness planes and cost-effectiveness acceptability curves (CEAC).

RESULTS

At 6 months, MMSE (adjusted mean difference = 0.92; 95% confidence interval (CI): 0.17 to 1.67; p = 0.02) and ETAM (adjusted mean difference = 1.00; CI: 0.14 to 1.85; p = 0.02) were significantly better in the intervention group. The adjusted cost difference was - €938.50 (CI: - 2733.65 to 763.13; p = 0.31). Given the CEAC, MAKS was cost-effective for 78.0% of MMSE and 77.4% for ETAM without a need for additional costs to payers.

CONCLUSIONS

MAKS is a cost-effective treatment to stabilize the ability to perform activities of daily living and cognitive abilities of people with MCI or mild to moderate dementia in German DCCs. Thus, MAKS should be implemented in DCCs.

Comfort and Satisfaction With Care of Home-Dwelling Dementia Patients at the End of Life

CONTEXT

Despite the preference to pass away at home, many dementia patients die in institutions, resulting in a paucity of studies examining end-of-life care outcomes in the home setting.

OBJECTIVE

The objective of this study was to identify modifiable factors associated with the comfort of dementia patients dying at home and families' satisfaction with care.

METHODS

This is a prospective cohort study conducted from October 2014 to April 2019 in Singapore. Dementia patients at Stage 7 on the Functional Assessment Staging Scale, with albumin <35 g/L, enteral feeding, or pneumonia, were recruited from a palliative homecare program. Independent variables included demographics, medical information, and care preferences. The Comfort Assessment in Dying with Dementia scale assessed dying patients' comfort, whereas the Satisfaction with Care at the End-of-Life in Dementia scale evaluated family caregivers' satisfaction two months after bereavement. Gamma regression identified factors independently associated with comfort and satisfaction.

RESULTS

The median age of 202 deceased patients whose comfort was assessed was 88 years. Anti-cholinergic prescription (60.4% of patients) [β (95% CI) = 1.823 (0.660-2.986), P = 0.002] was positively associated with comfort, whereas opioid prescription (89.6%) [β (95% CI) = -2.179 (-4.107 to -0.251), P = 0.027] and >1 antibiotic courses used in the last two weeks of life (77.2%) [β (95% CI) = -1.968 (-3.196 to -0.740), P = 0.002] were negatively associated. Independent factors associated with families' satisfaction with care were comfort [β (95% CI) = 0.149 (0.012-0.286), P = 0.033] and honoring of medical intervention preferences (96.0%) [β (95% CI) = 3.969 (1.485-6.453), P = 0.002].

CONCLUSION

Achieving comfort and satisfaction with care for dementia patients dying at home involves an interplay of modifiable factors. Honoring medical intervention preferences, such as those with palliative intent associated with patients' comfort, determined families' satisfaction with care.

Claims data-based analysis of the influence of individual and regional characteristics on the utilisation of long-term care by people with dementia in Baden-Wurttemberg, Germany

Background

Challenges of future dementia care include increasing shortage of qualified healthcare providers and decreasing potential of informal care by relatives. In order to meet those challenges, changes in dementia care are needed. These changes should be based on data of both care utilisation and care supply. The aim of this study was to provide insight into individual and regional characteristics that influence the utilisation of long-term care by people with dementia.

Methods

The study was a retrospective cross-sectional analysis of claims-based data and other available data referring to one index year. All data were aggregated for small geographic districts. The study population comprised people with a dementia diagnosis, 65 years and older in Baden-Wuerttemberg and insured by the largest health insurer. Utilisation of nursing home care, informal care, and respite care was analysed using binary coded logistic multilevel analyses.

Results

Seventy nine thousand three hundred forty-nine people with dementia were included in the analyses. Nursing home care was used by 20.4%, informal care by 30.6%, and respite care by 3.5% of people with dementia. Individual characteristics that influence care utilisation included age, sex and the level of care dependency. The utilisation of informal care (OR = 1.713) and respite care (OR = 2.036) was higher in rural districts than in city districts. Respite care supply had an effect on the utilisation of respite care (OR = 1.173).

Conclusions

The study found differences between districts in the utilisation of long-term care for dementia. These differences were largely explained by the composition of the population within the districts. An exception was the utilisation of respite care, which was higher in districts which have higher supply. Individual characteristics that influenced care utilisation are age, sex, level of care dependency and, with regard to informal care, comorbidity. Further research should be conducted on a small-area level, include further individual characteristics as well as other care and living forms.

Home care service utilisation by people with dementia-A retrospective cohort study of community nursing data in Australia

Progressive aged care reforms are shifting dementia care into the community. These efforts have been shown to prevent transition to residential aged care facilities and hospitals. There is a paucity of studies examining the utilisation of home care services for people living with dementia. This study aims to address the current knowledge gap by providing a comprehensive summary of older adults receiving home care and comparing service use for people with and without dementia. A retrospective secondary data analysis was conducted using routine data prospectively collected from a cohort (n = 2,703 with dementia matched to 9,224 without dementia; total 11,927) using a community home nursing service in metropolitan Melbourne, Australia, in 2014. Descriptive statistics compared individuals with and without dementia on client-level demographics and their episode of home care service use. A comparative analysis on select variables was also performed using a conditional Poisson regression to estimate relative risk (RR). Compared to older adults without dementia, people with dementia were more likely to be born overseas (RR 1.10, 95% CI [1.03-1.19]), require an interpreter (RR 1.41, 95% CI [1.26-1.59]), and live with family (RR 1.09 [1.01-1.16]). When examining an individual's episode of care, people with dementia were more likely to require acute care (RR 1.07, 95% CI [1.01-1.14]) and be discharged from home care with personal care services (RR 1.46, 95% CI [1.24-1.72]). People with dementia were less likely to be referred from a hospital (RR 0.73, 95% CI [0.69-0.77]), achieve their home care goals (RR 0.91, 95% CI [0.87-0.94]), or die while in receipt of home care services (RR 0.82, 95% CI [0.72-0.94]). Our findings suggest that people with dementia have different socio-demographic characteristics and interactions with home care services compared to people without dementia.

Day care vs home care: Effects on functional health outcomes among long-term care beneficiaries with dementia in Korea

OBJECTIVES

First, to compare changes in cognitive function, behavioral symptoms, and physical function for Korean Long-Term Care Insurance (LTCI) beneficiaries with dementia in day care (DC) and home care (HC) settings over 1 year. Second, to examine the association between LTCI service type and the aforementioned health outcomes.

METHODS

A retrospective matched cohort study was conducted using the national data set of the National Health Insurance Service in Korea. We identified 7822 beneficiaries with dementia who received either DC or HC services consistently for 1 year from 2008 to 2009. The propensity score matching method was used, yielding 416 participants in each group. Paired samples t-tests and logistic regression analyses were conducted.

RESULTS

Baseline differences between the two groups are present. According to multiple regression models, DC, when compared with HC, was related to less deterioration in cognitive and physical function but was associated with less improved behavioral symptoms 1 year after the LTCI enrollment. In the comparison between matched cohorts, DC, when compared with HC, was associated with less cognitive decline, less disability progression, and similar decrease in behavioral symptoms.

CONCLUSIONS

Cognitive function and disability declined less in the DC group, compared with the HC group. Conversely, behavioral symptoms showed a similar decrease between the two groups after 1-year follow-up. Further research is necessary to examine key features of DC services that have helped delay functional deterioration and alleviate behavioral symptoms.

Perceptions of collaborative relationships between seven different health care professions in Northern Italy

This article presents quantitative findings from a mixed method study that aimed to explore the status quo of interprofessional collaboration (IPC) in a Health Trust, located in a trilingual region in Northern Italy. The survey targeted seven health professions (physicians, nurses, dieticians, occupational therapists, physiotherapists, speech therapists, and psychologists). The survey was distributed online to more than 5,000 health professionals and completed by 2,238. This paper presents results on the frequency of collaboration as well as data from a multiple-group measurement scale for assessing IPC. Descriptive statistics were calculated for continuous variables while categorical data were analysed as counts and percentages. Pearson's Chi-square test and Fisher's exact test were calculated while Mann Whitney and Kruskal Wallis tests were applied to analyse statistical differences in IPC between groups according to sociodemographic variables. In general, our survey data showed that participants, perceived IPC in a positive way, even if the analysis indicated heterogeneity in the level of collaboration expressed. We also found that not all professions had an opportunity to collaborate with others. In addition, we found evidence to suggest that the way health care is organised impacted on perceptions of collaboration between the health professionals in this study. This study provides an initial insight into the perceived levels of IPC within a North Italian context. As such, it offers an account of the strengths and weaknesses of IPC from seven different professional groups based in this region of Europe.

Determinants of hospitalization and length of stay among people with dementia - An analysis of statutory health insurance claims data

OBJECTIVE

Dementia is a crucial challenge in acute care hospitals. Using a retrospective claims data cohort, this paper explores dementia patients' acute hospitalization rates, risk factors, and length of stay.

METHODS

The study used claims data from AOK PLUS, the largest statutory health insurance service (SHI) in Saxony, a federal state of Germany. The analysis included 61,239 people with dementia and 183,477 control subjects, all 65 years and older. Control subjects were age, gender, and regionally matched in a 1:3 ratio. Negative binomial hurdle regression was used to compare differences in hospitalization for the year 2014.

RESULTS

People with dementia had 1.49 times higher adjusted odds of being hospitalized at least once (95% confidence interval [CI], 1.46-1.52). Among those individuals hospitalized at least once, dementia increased the number of readmissions by 18% (95% CI, 1.15-1.20). Dementia patients also had a 1.74 times higher odds for at least one emergency admission compared to individuals without dementia (95% CI, 1.70-1.78). Dementia patients' admission risk factors included having care dependency, being recently diagnosed with dementia and living outside a metropolitan region. The increased length of stay for people with dementia per year was mainly attributable to higher admission rates.

CONCLUSIONS

Dementia patients are at higher risk for hospitalization, especially if they live outside the metropolitan region. Healthcare systems need to respond to the challenges resulting from the predicted demographic developments and increasing burden of dementia in the general population.

Healthcare utilization and costs in primary care patients with dementia: baseline results of the DelpHi-trial

The objectives of this cross-sectional analysis were to determine healthcare resource utilization and cost for community-dwelling patients with dementia (PWD) from a payer's and societal perspective, and to analyze the associations between costs and sociodemographic and clinical variables. Analysis of healthcare costs from a payer's perspective was based on a sample of 425 PWD, analysis of healthcare costs from societal perspective on a subsample of 254 PWD and their informal caregivers. Frequency of healthcare resource utilization was assessed by means of questionnaires. Informal care and productivity losses were assessed by using the Resource Utilization in Dementia questionnaire (RUD). Costs were monetarized using standardized unit costs. To analyze the associations, multiple linear regression models were used. Total annual costs per PWD valued 7016€ from a payer's and 25,877€ from a societal perspective, meaning that societal cost is approximately three and a half times as much as payer's expenditures. Costs valuated 5456 € for medical treatments, 1559 € for formal care, 18,327€ for informal care. Productivity losses valued 1297€ for PWD caregivers. Informal care could vary substantially (-21%; +33%) concerning different valuation methods. Medical care costs decreased significantly with progression of dementia and with age. Costs of care double over the stages of dementia. Formal care costs were significantly higher for PWD living alone and informal care costs significantly lower for PWD with an employed caregiver. For all cost categories, deficits in daily living activities were major cost drivers.

Nursing Home Use Across The Spectrum of Cognitive Decline: Merging Mayo Clinic Study of Aging With CMS MDS Assessments

BACKGROUND/OBJECTIVES

Objective, complete estimates of nursing home (NH) use across the spectrum of cognitive decline are needed to help predict future care needs and inform economic models constructed to assess interventions to reduce care needs.

DESIGN

Retrospective longitudinal study.

SETTING

Olmsted County, MN.

PARTICIPANTS

Mayo Clinic Study of Aging participants assessed as cognitively normal (CN), mild cognitive impairment (MCI), previously unrecognized dementia, or prevalent dementia (age = 70-89 years; N = 3,545).

MEASUREMENTS

Participants were followed in Centers for Medicare and Medicaid Services (CMS) Minimum Data Set (MDS) NH records and in Rochester Epidemiology Project provider-linked medical records for 1-year after assessment of cognition for days of observation, NH use (yes/no), NH days, NH days/days of observation, and mortality.

RESULTS

In the year after cognition was assessed, for persons categorized as CN, MCI, previously unrecognized dementia, and prevalent dementia respectively, the percentages who died were 1.0%, 2.6%, 4.2%, 21%; the percentages with any NH use were 3.8%, 8.7%, 19%, 40%; for persons with any NH use, median NH days were 27, 38, 120, 305, and median percentages of NH days/days of observation were 7.8%, 12%, 33%, 100%. The year after assessment, among persons with prevalent dementia and any NH use, >50% were a NH resident all days of observation. Pairwise comparisons revealed that each increase in cognitive impairment category exhibited significantly higher proportions with any NH use. One-year mortality was especially high for persons with prevalent dementia and any NH use (30% vs 13% for those with no NH use); 58% of all deaths among persons with prevalent dementia occurred while a NH resident.

CONCLUSIONS

Findings suggest reductions in NH use could result from quality alternatives to NH admission, both among persons with MCI and persons with dementia, together with suitable options for end-of-life care among persons with prevalent dementia.

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.

Lifetime Occupation and Late-Life Cognitive Performance Among Women

We examined whether women who had regular jobs throughout life performed better cognitively than older adult housewives. Linear regression was used to compare global cognitive performance scores of housewives (G1) and women exposed to work of low (G2) and high (G3) complexity. The sample comprised 477 older adult Brazilian women, 430 (90.4%) of whom had performed lifelong jobs. In work with data, the G2 group's cognitive performance scores were 1.73 points higher (p =.03), and the G3 group scored 1.76 points (p =.02) higher, than the G1. In work with things and with people, the G3 scored, respectively, 2.04 (p <.01) and 2.21 (p <.01) cognitive test points higher than the G1. Based on our findings we suggest occupation of greater complexity is associated with better cognitive performance in women later in life.

Competing-risks duration models with correlated random effects: an application to dementia patients' transition histories

Multi-state transition models are widely applied tools to analyze individual event histories in the medical or social sciences. In this paper, we propose the use of (discrete-time) competing-risks duration models to analyze multi-transition data. Unlike conventional Markov transition models, these models allow the estimated transition probabilities to depend on the time spent in the current state. Moreover, the models can be readily extended to allow for correlated transition probabilities. A further virtue of these models is that they can be estimated using conventional regression tools for discrete-response data, such as the multinomial logit model. The latter is implemented in many statistical software packages and can be readily applied by empirical researchers. Moreover, model estimation is feasible, even when dealing with very large data sets, and simultaneously allowing for a flexible form of duration dependence and correlation between transition probabilities. We derive the likelihood function for a model with three competing target states and discuss a feasible and readily applicable estimation method. We also present the results from a simulation study, which indicate adequate performance of the proposed approach. In an empirical application, we analyze dementia patients' transition probabilities from the domestic setting, taking into account several, partly duration-dependent covariates.

Increased healthcare service utilizations for patients with dementia: a population-based study

Background

The majority of previous studies investigating the health care utilization of people with dementia were conducted in Western societies. There is little information on the economic burden on the healthcare system attributable to dementia in Asian countries. This study thus investigated differences in utilization of healthcare services between subjects with and those without a diagnosis of dementia using Taiwan’s National Health Insurance population-based database.

Methods

This study comprised 5,666 subjects with a dementia diagnosis and 5,666 age- and gender-matched comparison subjects without a dementia diagnosis. We individually followed each subject for a 1-year period starting from their index date to evaluate their healthcare resource utilization. Healthcare resource utilization included the number of outpatient visits and inpatient days, and the mean costs of outpatient and inpatient treatments. In addition, we divided healthcare resource utilization into psychiatric and non-psychiatric services.

Results

As for utilization of psychiatric services, subjects with a dementia diagnosis had significantly more outpatient visits (2.2 vs. 0.3, p<0.001) and significantly higher outpatient costs (US$124 vs. US$16, p<0.001) than comparison subjects. For non-psychiatric services, subjects with a dementia diagnosis also had significantly more outpatient visits (34.4 vs. 31.6, p<0.001) and significantly higher outpatient costs (US$1754 vs. US$1322, p<0.001) than comparison subjects. For all healthcare services, subjects with a dementia diagnosis had significantly more outpatient visits (36.7 vs. 32.0, p<0.001) and significantly higher outpatient costs (US$1878 vs. US$1338, p<0.001) than comparison subjects. Furthermore, the total cost was about 2-fold greater for subjects with a dementia diagnosis than for comparison subjects (US$3997 vs. US$2409, p<0.001).

Conclusions

We concluded that subjects who had received a clinical dementia diagnosis had significantly higher utilization of all healthcare services than comparison subjects.

Health Care Service Utilization of Dementia Patients before and after Institutionalization: A Claims Data Analysis

BACKGROUND

Community-based and institutional dementia care has been compared in cross-sectional studies, but longitudinal information on the effect of institutionalization on health care service utilization is sparse.

METHODS

We analyzed claims data from 651 dementia patients via Generalized Estimation Equations to assess health care service utilization profiles and corresponding expenditures from four quarters before to four quarters after institutionalization.

RESULTS

In all domains, utilization increased in the quarter of institutionalization. Afterwards, the use of drugs, medical aids, and non-physician services (e.g., occupational therapy and physiotherapy) remained elevated, but use of in- and outpatient treatment decreased. Cost of care showed corresponding profiles.

CONCLUSION

Institutional dementia care seems to be associated with an increased demand for supportive services but not necessarily for specialized medical care.

Which need characteristics influence healthcare service utilization in home care arrangements in Germany?

Background

We see a growing number of older adults receiving long-term care in industrialized countries. The Healthcare Utilization Model by Andersen suggests that individual need characteristics influence utilization. The purpose of this study is to analyze correlations between need characteristics and service utilization in home care arrangements.

Methods

1,152 respondents answered the questionnaire regarding their integration of services in their current and future care arrangements. Care recipients with high long-term care needs answered the questionnaire on their own, the family caregiver assisted the care recipient in answering the questions, or the family caregiver responded to the questionnaire on behalf of the care recipient. They were asked to rank specific needs according to their situation. We used descriptive statistics and regression analysis.

Results

Respondents are widely informed about services. Nursing services and counseling are the most used services. Short-term care and guidance and training have a high potential for future use. Day care, self-help groups, and mobile services were the most frequently rejected services in our survey. Women use more services than men and with rising age utilization increases. Long waiting times and bad health of the primary caregiver increases the chance of integrating services into the home care arrangements.

Conclusion

The primary family caregiver has a high impact on service utilization. This indicates that the whole family should be approached when offering services. Professionals should react upon the specific needs of care dependents and their families.

Subjective caregiver burden: validity of the 10-item short version of the Burden Scale for Family Caregivers BSFC-s

BACKGROUND

Subjective burden is a central variable describing the situation encountered by family caregivers. The 10-item short version of the Burden Scale for Family Caregivers (BSFC-short/BSFC-s) was developed to provide an economical measure of this variable. The present study examined the reliability and validity of the BSFC-s.

METHODS

Comprehensive data from "the IDA project" were the basis of the calculations, which included 351 dyads and examined medical data on people with dementia, interview data from their family caregivers, and health insurance data. A factor analysis was performed to explore the structure of the BSFC-s; Cronbach's alpha was used to evaluate the internal consistency of the scale. The items were analyzed to determine the item difficulty and the discriminatory power. Construct validity was tested with five hypotheses. To establish the predictive validity of the BSFC-s, predictors of institutionalization at a follow-up time of 2.5 years were analyzed (binary logistic regression).

RESULTS

The BSFC-s score adhered to a one-factor structure. Cronbach's alpha for the complete scale was .92. A significant increase in the BSFC-s score was observed when dementia progressed, disturbing behavior occurred more frequently, care requirements increased, and when caregivers were diagnosed with depression. Caregiver burden was the second strongest predictor of institutionalization out of a total of four significant predictors.

CONCLUSIONS

All hypotheses that referred to the construct validity were supported. The BSFC-short with its ten items is a very economical instrument for assessing the caregiver's total subjective burden in a short time frame. The BSFC-s score has predictive validity for the institutionalization of people with dementia. Therefore it is an appropriate outcome measure to evaluate caregiver interventions. The scale is available for free in 20 languages (http://www.caregiver-burden.eu). This availability facilitates the comparison of international research findings.

A claims data-based comparison of comorbidity in individuals with and without dementia

BACKGROUND

Multimorbidity is common in advanced age, and is usually associated with negative - yet to some extent preventable - health outcomes. Detecting comorbid conditions is especially difficult in individuals with dementia, as they might not always be able to sufficiently express discomfort. This study compares relevant comorbidity complexes in elderly people with and without dementia, with a particular look at gender- and living environment-specific differences. Moreover, associations between selected comorbid conditions and dementia are reviewed more closely.

METHODS

Using 2006 claims data from a large German Statutory Health Insurance fund, 9,139 individuals with dementia and 28,614 age- and gender-matched control subjects aged 65 years and older were identified. A total of 30 comorbidity complexes were defined based on ICD-10 codes. Corresponding prevalence rates were calculated, and the association between a distinct condition and dementia was evaluated via logistic regression in the overall sample as well as in analyses stratified by gender and living environment.

RESULTS

Individuals with dementia were more likely to be diagnosed with 15 comorbidity complexes, including Parkinson's, stroke, diabetes, atherosclerosis (supposed dementia risk factors) or fluids and electrolyte disorders, insomnia, incontinence, pneumonia, fractures and injuries (supposed sequelae). In contrast, they were less likely to be diagnosed with 11 other conditions, which included vision and hearing problems, diseases of the musculoskeletal system, lipoprotein disorders and hypertension. In a gender-stratified analysis, the patterns remained largely the same, but a bigger comorbidity gap between cases and control subjects emerged in the male population. Restricting the analysis to community-living individuals did not lead to any substantial changes.

CONCLUSION

Besides strengthening the evidence on accepted dementia risk factors and sequelae, the analyses point to particular conditions that are likely to remain untreated or even undiagnosed. This issue seems to affect male and female individuals with dementia to varying degrees. Raising awareness of these conditions is important to possibly preventing comorbidity-associated complications and disease progression in dementia patients. To more comprehensively understand the mutual interactions between dementia and comorbidity, further research on diagnostic and treatment attitudes regarding comorbidity in dementia patients and on their gender-specific health-seeking behaviour seems to be required.
