The personal cost of dementia care in Japan: A comparative analysis of residence types

Health Care Resource Use and Social Costs in Mild Cognitive Impairment and Mild Alzheimer's Disease

Background

As the number of patients with dementia increases, so do the social costs. In recent years, attempts have been made to reduce risk to be dementia and treat it from the early stages of the disease, making it important to estimate the costs of the early stages.

Objective

To estimate the medical and social costs of the early stages of Alzheimer's disease (AD), which include mild cognitive impairment (MCI) due to AD and mild AD.

Methods

Questionnaires were used to obtain basic information (e.g., age, cognitive function) and medical costs, social care costs, family caregiver medical costs, and family caregiver informal care costs from patients with MCI due to AD or mild AD who were attending a memory clinic. A comparison was then conducted between these two groups.

Results

Patients with mild AD had higher total costs, patient medical costs, patient social care costs, and family caregiver informal care costs than did patients with MCI; however, only patient medical costs were significantly different (p = 0.022). A detailed analysis of patient medical costs revealed that anti-dementia drug treatment costs were significantly higher in patients with mild AD (p <  0.001).

Conclusion

Compared with patients with mild AD, those with MCI may have lower patient and family caregiver costs. As it is important to reduce social costs through risk reduction and therapeutic interventions from the early stages of AD, the present findings could help estimate the social costs and verify the cost-effectiveness of early interventions for AD.

Association between advance care planning and depressive symptoms among community-dwelling people with dementia: An observational cross-sectional study during the COVID-19 pandemic in Japan

Objectives

Advance care planning (ACP) is an increasing priority for people with dementia during the COVID-19 pandemic. This study evaluated the association between ACP initiation and depressive symptoms among home-dwelling people living with dementia.

Methods

An internet-based questionnaire survey was conducted with Japanese family caregivers of home-dwelling persons with dementia in June 2021. Family caregivers evaluated the level of depressive symptoms in persons with dementia using the Neuropsychiatric Inventory (NPI). Caregivers also rated the quality of life of persons with dementia using the EQ-5D-5L.

Results

A total of 379 family caregivers participated in the survey. Depressive symptoms were reported in 143 persons with dementia (37.7%). A total of 155 persons with dementia (40.9%) had initiated ACP, of which 88 (56.8%) had care professionals involved in ACP conversation. After adjusting for the characteristics of persons with dementia and caregivers, persons with professional involvement showed significantly more severe depressive symptoms compared to those who did not initiate ACP. There was no significant difference in the quality of life of persons with dementia according to ACP initiation.

Conclusions

Many home-dwelling persons with dementia experienced depressive symptoms during the COVID-19 pandemic, especially in cases where care professionals were involved in ACP conversations. Optimal and proactive ACP approaches need to be developed to prevent depressive symptoms in newly diagnosed persons.

Family caregivers' concerns about advance care planning for home-dwelling people with dementia: a cross-sectional observational study in Japan

Background

The importance of advance care planning for people with dementia has increased during the Coronavirus Disease 2019 Pandemic. However, family caregivers may have concerns about having conversations regarding advance care planning with their loved ones, which may hinder the initiation of such planning. This study investigated family caregivers’ concerns regarding conducting advance care planning for home-dwelling individuals with dementia.

Methods

A prospective cross-sectional study compared the level of family-caregiver concern between those who had initiated advance care planning and those who did not. In June 2021, an internet-based questionnaire survey was administered to Japan-based family caregivers of persons with dementia. Registered members of a Japan-based survey company were recruited; inclusion criteria were being aged 40 years or older and having been a primary, non-professional caregiver of a family member with dementia. Respondents rated their level of agreement with six statements regarding advance-care-planning-related concerns. Respondents also reported their psychological well-being using the WHO-5 Well-Being Index.

Results

Overall, 379 family caregivers participated in this survey. Of these, 155 (40.9%) reported that their loved ones had initiated advance care planning, of whom 88 (56.8%) stated that care professionals were involved in the advance-care-planning conversations. The level of family-caregiver concern was significantly lower when the loved one initiated the conversation concerning advance care planning. After adjusting for the characteristics of persons with dementia and their caregivers, family caregivers with lower psychological well-being showed significantly higher levels of concern.

Conclusions

Family caregivers reported concerns regarding conducting advance care planning. There is a need for educational and clinical strategies that encourage professionals to address the psychological needs of family caregivers.

Which factors increase informal care hours and societal costs among caregivers of people with dementia? A systematic review of Resource Utilization in Dementia (RUD)

BACKGROUND

Nearly 19 million people across OECD countries are living with dementia, and millions of family caregivers are affected by the disease. The costs of informal care are estimated to represent 40-75% of the total dementia cost exceeding formal care time and medical costs.

OBJECTIVE

To conduct a systematic review to evaluate the methodological quality and factors associated with high informal care hours per month that increase societal costs, and to identify what type of interventions may alleviate the entire burden of informal and formal caregiving.

METHODS

The systematic review was registered at PROSPERO (15.12.2020). A search in Medline, Embase, PsycINFO, and web of science for observational studies, cost-effectiveness, and cost of illness (COI) analyses on resource utilization in dementia (RUD) was conducted on 1 December 2020. Our inclusion criteria included a requirement that studies had to use the original RUD, RUD-FOCA or RUD lite in terms of hours or days per month, and costs as primary or secondary outcome, OECD countries, within the last 20 years and a sample population comprising persons with dementia (PwD) ≥65 years and their caregivers. We followed the PRISMA, GRADE, PICO guidelines and Drummond criteria to assess the methodology and quality of the studies.

RESULTS

Of 307 studies, 26 cross-sectional and 3 longitudinal cohort studies were included in the analyses. Two studies had a randomized controlled trial (RCT) design. The methods and cost categories in each study varied widely. Disease severity, caregiver factors, and behavioural and psychological symptoms of dementia (BPSD) were associated with high informal care hours and societal cost. One RCT found no effect of a non-pharmacological intervention on informal care hours, yet another RCT found a cost-effective impact of an in-home respite care programme reducing informal care burden and costs.

CONCLUSION

The divergent use of the RUD components within included studies encourage more harmonized analyses. There are only two RCTs on RUD, one of which shows a significant treatment effect. Larger sample sizes and longer follow-up periods are required in future RCTs with dedicated focus on cost-enhancing and resource intensive factors such as disease severity and BPSD. Novel interventions must diversify between caregiver and PwD groups.

Trajectories of end-of-life medical and long-term care expenditures for older adults in Japan: retrospective longitudinal study using a large-scale linked database of medical and long-term care claims

BACKGROUND

An accurate understanding of the current state of end-of-life care is important for healthcare planning. The objectives of this study were to examine the trajectories of end-of-life medical and long-term care expenditures and associated factors.

METHODS

This was a retrospective longitudinal study using a large-scale linked database of medical and long-term care claims-National Health Insurance, Advanced Elderly Medical Insurance, and long-term care insurance-covering Prefecture A in Japan. Patients aged ≥70 years who died between April 1, 2016, and March 31, 2017, were included (N = 16,084 patients; mean age = 85.1 ± 7.5 years; 7804 men (48.5%) and 8280 women (51.5%)). The outcome measures were medical expenditures (inpatient, outpatient, and prescription), long-term care expenditures, and total healthcare expenditures (the sum of medical and long-term care expenditures) during the 60 months before the date of death. We calculated each patient's monthly medical and long-term care expenditures for 60 months before the date of death and applied group-based trajectory modeling to identify distinct trajectories. Factors associated with spending trajectories were examined via multinomial logistic regression analyses. Explanatory variables included age, sex, diseases, and the medical services used.

RESULTS

We identified six distinct spending trajectories for the total healthcare expenditures: high persistent (45.6%), medium-to-high persistent (26.1%), early rise then high persistent (9.8%), late rise (6.4%), low persistent then very late rise (i.e., when spending starts increasing later than "late rise"; 6.4%), and progressive increase (5.7%). Factors associated with the high-persistent trajectory were chronic illnesses, various organ failures, neurodegenerative diseases, fractures, and tube feeding. The trajectory pattern of medical expenditures was similar to that of total healthcare expenditures; however, a different pattern was seen for long-term care expenditures.

CONCLUSIONS

Regarding combined medical and long-term care spending of the last 5 years, most patients belonged to a pattern in which the healthcare expenditures remained high, and a combination of multiple factors contributed to these patterns. This finding can offer healthcare providers a longer-term perspective on end-of-life care.

The impact of long-term care service on total lifetime medical expenditure among older adults with dementia

Along with the rapid increase in older adult population in South Korea, the management of dementia is becoming important. Higher dementia prevalence inevitably leads to an excessive burden on medical expenditure throughout one's life, so the catastrophic health expenditure for dementia should be protected in the aspect of both nation and family. Therefore, this study attempted to estimate the lifetime medical expenditures (LE) of older adults with dementia, and confirmed if the long-term care insurance (LTCI) is effective in reducing their medical expenses. The study analyzed LE of adults, aged over 70 years, using a cohort database and simulated the total LE per capita. In order to compare the differences in LE due to dementia, propensity score matching (PSM) was performed. As of 2015, the total LE per capita for older adults with dementia and without dementia was estimated to be 76,973 thousand won ($65,427) and 31,105 thousand won ($26,439). Older adults with dementia had 2.4 times more expenditure than those without dementia. In particular, the LE per capita for hospitalization of dementia patients was 63,945 thousand won ($54,353), which was about 5 times higher than LE per capita for outpatient treatment. In addition, as a result of confirming the political effectiveness of LTCI, the LE for older adults with dementia, who had not used the long-term care service (LTCS), was estimated to be about 85,769 thousand won ($72,904). Conversely, LTCS users were estimated to spend 70,487 thousand won ($59,914), which means that LTCS non-users spent about 22% more on total LE than LTCS users. Non-users spent about half of their LE after the age of 80. Based on these findings, this study confirmed that the LTCI system had the desired effect of reducing the total LE for older adults with dementia.

Classification tree model of the personal economic burden of dementia care by related factors of both people with dementia and caregivers in Japan: a cross-sectional online survey

OBJECTIVE

The purpose of this study was to clarify the microlevel determinants of the economic burden of dementia care at home in Japanese community settings by classifying them into subgroups of factors related to people with dementia and their caregivers.

DESIGN

A cross-sectional online survey.

PARTICIPANTS

4313 panels of Japanese research company who fulfilled the following criteria: (1) aged 30 years or older, (2) non-professional caregiver of someone with dementia, (3) caring for only one person with dementia and (4) having no conflicts of interest with advertising or marketing research entities.

PRIMARY OUTCOME MEASURES

Informal care costs and out-of-pocket payments for long-term care (LTC) services.

RESULTS

From 4313 respondents, only 1383 caregivers in community-settings were included in this analysis. We conducted a χ² automatic interaction detection analysis to identify the factors related to each cost (informal care costs and out-of-pocket payments for LTC services) divided into subcategories. In the resultant classifications, informal care cost was mainly related to caregivers' employment status. When caregivers acquired family care leave, informal care costs were the highest. On the other hand, out-of-pocket payments for LTC were related to care-need levels and family economic status. Activities of Daily Living and Instrumental Activities of Daily Living functions such as bathing, toileting and cleaning were related to all costs.

CONCLUSION

This study clarified the difference in dementia care costs between classified subgroups by considering the combination of the situations of both people with dementia and their caregivers. Informal care costs were related to caregivers' employment and cohabitation status rather to the situations of people with dementia. On the other hand, out-of-pocket payments for LTC services were related to care-need levels and family economic status. These classifications will be useful in understanding which situation represents a greater economic burden and helpful in improving the sustainability of the dementia care system in Japan.

Care preferences of healthy, middle-aged adults in Japan and the USA if they acquired dementia: A cross-sectional observational study

AIM

Japan introduced dementia-friendly initiatives into its national policies to help people with dementia remain involved in society for as long as possible. However, some people might choose to live in a nursing home to avoid care burden on family members. Understanding middle-aged adults' preferences for place of care and identifying factors that influence their preferences would help policy decision-makers promote dementia-friendly initiatives. The present study aimed to investigate the care preferences of middle-aged adults if they acquired dementia in Japan and the USA.

METHODS

We carried out a cross-sectional observational study using an internet-based questionnaire survey of Japanese residents with Japanese ethnicity, Japanese Americans, and non-Asian Americans aged 40-70 years. A total of 301 participants, including 104 Japanese residents, 93 Japanese Americans and 104 non-Asian Americans, completed the survey. Participants were asked to answer the items based on a hypothetical situation in which they had acquired dementia requiring regular care and supervision.

RESULTS

Participants preferred nursing home care (29.9%), followed by professional home care (19.6%), family home care (17.6%) and hospital care (11.3%). Japanese residents had a significantly lower preference for professional home care than did Japanese or non-Asian Americans (adjusted odds ratio 0.28, 95% confidence interval 0.10-0.75). Between-ethnicity difference in care preferences was not observed.

CONCLUSIONS

A low preference for professional home care among the middle-aged adults might be influenced by country-specific long-term and dementia care systems. Policy decision-makers should develop professional home care services that are more available for families of people living with dementia. Geriatr Gerontol Int 2019; 19: 829-833.
