Observational study of frailty in older Japanese patients with non-valvular atrial fibrillation receiving anticoagulation therapy.

The number of patients with atrial fibrillation is increasing, and frailty prevalence increases with age, posing challenges for physicians in prescribing anticoagulants to such patients because of possible harm. The effects of frailty on anticoagulant therapy in older Japanese patients with nonvalvular atrial fibrillation (NVAF) are unclear. Herein, we prescribed rivaroxaban to Japanese patients with NVAF and monitored for a mean of 2.0years. The primary endpoint was stroke or systemic embolism. The secondary endpoints were all-cause or cardiovascular death, composite endpoint, and major or non-major bleeding. Frailty was assessed using the Japanese long-term care insurance system. A multiple imputation technique was used for missing data. The propensity score (PS) was obtained to estimate the treatment effect of frailty and was used to create two PS-matched groups. Overall, 5717 older patients had NVAF (mean age: 73.9years), 485 (8.5%) were classified as frail. After PS matching, background characteristics were well-balanced between the groups. Rivaroxaban dosages were 10 and 15mg/day for approximately 80% and the remaining patients, respectively. Frailty was not associated with the primary endpoint or secondary endpoints. In conclusion, frailty does not affect the effectiveness or safety of rivaroxaban anticoagulant therapy in older Japanese patients with NVAF.Trial registration: UMIN000019135, NCT02633982.

Effect of Early Rehabilitation Services After Discharge on Social Activity Among Chronic Stroke Survivors: A Multicenter Prospective Study

BackgroundSocial inactivity after a stroke leads to adverse outcomes, making social activity after discharge important for chronic stroke survivors. ObjectivesTo investigate the effects of early rehabilitation services after discharge on social activity among chronic stroke survivors. MethodsThe participants were prospectively recruited from three convalescent hospitals. Receipt of early rehabilitation services after discharge for chronic stroke survivors was defined as the utilization of day care or home-based rehabilitation services by the Japanese long-term care insurance system. Social activity was assessed using the Frenchay Activities Index (FAI) premorbid and at 3, 6, and 12 months after discharge. In this study, the outcome was defined as the change in the FAI score from 3 to 12 months after discharge. Multivariate regression analysis was performed to examine the effect of access to rehabilitation on changes in FAI. ResultsNinety stroke survivors (age 67.2 ± 11.6 years, 52 male) were enrolled. The FAI showed improvements by 27.4% and 1.4% from 3 to 12 months after discharge in the rehabilitation and non-rehabilitation groups, respectively. Multivariate regression analysis showed that access to rehabilitation after discharge was positively associated with the FAI change from 3 to 12 months after discharge (B = 30.3, β = 0.38, 95% confidence interval = 11.13–49.47, p = 0.002). ConclusionEarly rehabilitation services after discharge were significantly associated with increased social activity.

Characteristics of first-time users of the nursing small-scale multifunctional home care service: a pooled cross-sectional study using Japanese long-term care insurance claims data from 2012 to 2019

ObjectivesIn April 2012, the Japanese government launched a new nursing service called the nursing small-scale multifunctional home care (NSMHC) to meet the nursing care demands of individuals with moderate-to-severe activities...

Fruit and Vegetable Intake and Risk of Disabling Dementia: Japan Public Health Center Disabling Dementia Study

BackgroundFruits and vegetables contain abundant amounts of antioxidant vitamins such as vitamin C, α-carotene, and β-carotene. Few prospective observational studies have investigated the effects of fruit and vegetable intake on the risk of dementia, and the results are inconsistent. ObjectivesOur aim was to examine associations between fruit and vegetable intake and the risk of disabling dementia. MethodsWe conducted a follow-up survey within the Japan Public Health Center-based Prospective Study involving 42,643 individuals aged 50–79 y at baseline (2000–2003). Dietary fruit and vegetable intakes and related antioxidant vitamin intakes (i.e., α-carotene, β-carotene, and vitamin C) were determined using a food frequency questionnaire. The diagnosis of disabling dementia was made based on the daily living disability status related to dementia under the Japanese long-term care insurance program from 2006 to 2016. Hazard ratios and 95% confidence intervals for disabling dementia were estimated using area-stratified Cox proportional hazard models adjusted for potential confounding factors. ResultsA total of 4994 cases of disabling dementia were recorded. We observed an inverse association between total fruit and vegetable intake and the risk of dementia among males and females: the multivariate hazard ratios (95% confidence intervals) for the highest compared with lowest quartiles of intake were 0.87 (0.76, 0.99) (P- trend = 0.05) among males and 0.85 (0.76, 0.94) (P- trend = 0.006) among females. Among antioxidant vitamins, vitamin C intake was inversely associated with the risk of dementia among males and females: the multivariate hazard ratios (95% confidence intervals) for the highest compared with lowest quartiles of intake were 0.71 (0.61, 0.84) (P- trend < 0.0001) among males, and 0.76 (0.67, 0.86) (P- trend < 0.0001) among females. ConclusionsFruit and vegetable intake and dietary intake of vitamin C may contribute to reducing the risk of disabling dementia among males and females.

Factors Contributing to Health Deterioration in the Japanese Long-Term Care Insurance System in Terms of Instrumental Activities of Daily Living

This study aimed to determine which instrumental activities of daily living (IADL) are associated with health deterioration from the “support level” to the “care level” among users of the long-term care insurance system in Japan. From April 2017 to March 2020, we conducted a retrospective follow-up survey on 178 Japanese community-dwelling older adults (64 men, 114 women) newly certified as support level. Independent variable was 8 IADL items and the outcome defined as the “support level maintenance time.” Cox models were used to assess the risk of health deterioration, with adjustments for age group, family composition, dementia status, and frailty status by gender. Dependence on 5 items, “laundry” (hazard ratio [HR] =2.5; 95% confidence interval [CI]: 1.1-5.8), “cooking” (HR = 3.7; 95% CI: 1.1-12.2), “telephone use” (HR = 2.4; 95% CI: 1.2-4.7), “financial management” (HR = 2.5; 95% CI: 1.2-5.0), and “medication management” (HR = 2.4; 95% CI: 1.2-4.8), was independently associated with a worse outcome among men, whereas dependence on “financial management” (HR = 2.6; 95% CI: 1.5-4.7) and “medication management” (HR = 2.0; 95% CI: 1.1-3.5) was independently associated with a worse outcome among women. These findings suggest that difficulties in “financial management” and “medication management” are common factors associated with health deterioration from the support to the care level among both genders. An association with household tasks was also seen among men, indicating that a paradigm shift is needed to increase the participation of men in household tasks.

Chronic pain in older adults with disabilities is associated with fall-related injuries: a prospective cohort study.

Previous studies have shown an association between chronic pain and the occurrence of falls in community-dwelling older adults; however, the association between chronic pain and fall-related injuries in older adults with disabilities is unclear. This study aimed to determine the association between chronic pain and fall-related injuries in older adults with disabilities. This 24-month prospective cohort study included older adults aged 65years or older using Japanese long-term care insurance services. Chronic pain, defined as "pain that has persisted for more than three months to date," was assessed using a face-to-face questionnaire. Fall-related injuries, defined as "injuries requiring hospitalization or outpatient treatment due to a fall," were assessed using a fall calendar. Data were analyzed using a Cox proportional hazards model, with fall-related injury as the dependent variable, chronic pain as the independent variable, and confounders as covariates. Among 133 included participants, 15 experienced fall-related injuries. After adjusting for age and sex as covariates, chronic pain was significantly associated with fall-related injuries (hazard ratio: 5.487, 95% confidence interval: 1.211-24.853, p = 0.027). Chronic pain was associated with fall-related injuries in older adults with disabilities. In this population, a greater focus should be placed on treating chronic pain to reduce the occurrence of falls.

HOME-BASED END-OF-LIFE CARE COOPERATION BETWEEN VISITING NURSES AND CARE MANAGERS IN JAPAN

Abstract End-of-life care patients use home-visit nursing services under Japanese long-term care insurance; however, they require a care manager to implement the care plan. However, the cooperation procedure of home-based medical care between visiting nurses and care managers has not been adequately researched. Thus, this study aimed to clarify the presence of support between visiting nurses and care managers to be adapted to this situation. This study was conducted in March and April 2023 at home-visit nursing stations located in a prefecture in Japan. Self-administered questionnaires were mailed to 192 visiting nurses in Japan, and 136 response forms (70.8%) were received through postal mails. A total of 130 questionnaires (67.7%) were determined to be valid responses, which also included the participants’ written consent for research. The presence or absence of work experience and the importance of collaboration in the preparatory, introductory, stable, and near-death stages of end-of-life care were answered. The presence of work experience at each stage was over 53.1%. The importance of collaboration at each stage was over 76.9%. Query regarding collaborating well with care managers was answered on a scale from 0 to 100 %. Good collaboration with care managers had an average score of 75.4%. The presence or absence of experience and the importance of collaboration items were clarified at each stage. The research findings could contribute to the development of education and training. This work was supported by JSPS KAKENHI Grant Number JP21K02802.

IMPROVING COGNITIVE FUNCTION IN THE NEW COHORT—BUT ONLY FOR MEN. FINDINGS FROM THE KYOTANGO CENTENARIAN STUDY

Abstract The Kyotango Centenarian Cohort Study was established with the aim of tracing long-term changes in the overall functioning of centenarians. This study started in 2014 in Kyotango City. Since then, new centenarians and those who were expected to be 100 years old the following April were invited to the study every year in September. Eligible centenarians were invited by the city, and centenarians and their families agreed to participate to answer questions either by mail or face-to-face interviews, according to their preference. For the non-participants, anonymized living conditions and care need levels were provided by the city. The number of centenarian candidates varied by year (24-55). However, the number of woman centenarians had increased through the 8-year surveyed period (31 and 42 for women, 10 and 9 for men in 2014 and 2021). On average, every year 40 new centenarians were invited and 80% of them participated in the survey. Among the functional variables, cognitive function was estimated by proxies, which had a high correlation with MMSE. No clear improving trend for nursing care level in Japanese long-term care insurance, as measured by activities of daily living and cognitive function rating, was observed. Meanwhile, an improving trend for cognitive function was observed among men but not among women. This might be caused by the gender difference in the survival ratio that frail women were more likely to survive. Future research should investigate possible reasons for a cohort improvement in Japanese centenarian men, and cognitive intervention programs should particularly target women.

DEMENTIA PREVENTION: THE COST-EFFECTIVENESS OF PREVENTION SERVICES IN JAPANESE LONG-TERM CARE SYSTEM

Abstract Objectives To analyze the cost-effectiveness of prevention services (Named “Support” in Japanese official documents) in Japanese Long-Term Care Insurance system, which draws data from a large volume of 10-year database in Osaka Prefecture. Design: We design an approach to estimate cost-effective prices using aggregate data including costs of dementia in 10 years, time of dementia first diagnosed, changes of care levels, and quality of life. Measurements: The outcomes were average annual expenditure per unit of services. Results In higher risk groups of dementia, prevention services delaying cognitive decline and enhancing quality of life were cost effective at $206 per individual. However, this cost-effectiveness will wear off as symptoms worsen and the care levels increase. Conclusion Prevention services from Long-Term Care Insurance system are possibly to be cost-effective, but this cost benefit is not long-term .

Evaluation of preventive care for swallowing difficulty through policy changes in Japanese long-term care insurance: analysis of a nationwide claims dataset for long-term care insurance

BackgroundSwallowing/feeding difficulty is a serious hidden health problem in the older population. Although oral intake services based on the degree of this difficulty have been provided and revised in Japanese public long-term care (LTC) insurance since 2006, their implementation has not been examined. We evaluated the impact of policy changes on these services.MethodsThe nationwide database of LTC service uses in Japan was analysed for three oral intake services: Enhanced Oral Function in daycare facilities whose users were slightly disabled, Maintenance of Oral Ingestion and Transition to Oral Ingestion from tube feeding in residential facilities. Data were extracted for each June from 2015 to 2020 when monthly usage of these services was aligned and each June from 2009 to 2020 for the proportion of users according to LTC insurance certification. The major policy changes were the addition of municipal provision in Enhanced Oral Function and a requirement for multidisciplinary collaboration in Maintenance of Oral Ingestion in 2015. The impact of the medical fee reduction for developing percutaneous gastro-tubing to Transition to Oral Ingestion was also examined.ResultsBetween 2015 and 2020, the use of Enhanced Oral Function and Maintenance of Oral Ingestion increased and Transition to Oral Ingestion decreased, resulting in a total increase in use of 275,000 times or approximately 5,000 times per 100,000 among all older adults with LTC insurance certification. Concerning the proportion of users’ disability status, the major users of Enhanced Oral Function in 2020 were slightly disabled and independent older adults (70%, up from 55% to 2009). Regarding the major users of Maintenance of Oral Ingestion between 2013 and 2020, care-need level 5 (most severe) decreased by 11%, whereas the total of care-need levels 4 and 3 increased by 9%. The use of Transition to Oral Ingestion, which had been declining, showed a further decline after reduction of the medical fee for percutaneous gastro-tubing in 2014.ConclusionsDue to policy changes, Enhanced Oral Function and Maintenance of Oral Ingestion have increased in the number of use among slightly disabled persons. However, this increase may be insufficient given the hidden swallowing/feeding difficulty.

Relationship between Total Kihon Checklist Score and Age-Specific Deaths among Late-Stage Older Adults in Otawara City (Aged 75 and Older) over a 15-Year Period

Introduction: While the Japanese long-term care insurance system supports an ageing society, there are concerns about the shortage of financial resources and labour force. Further, extending healthy life expectancy and narrowing the gap with the average life expectancy are important issues. In this study, we aimed to examine, over a 15-year period, the relationship between the total Kihon Checklist (t-KCL) score and age-specific deaths among late-stage older adults aged 75 and older who were not certified for long-term care insurance. Methods: The participants were older adults residing in Otawara City, Tochigi Prefecture, who were aged 75 years or older as of 2006. The participants, who were not certified by the long-term care insurance system, were asked to complete the KCL by a community welfare committee member. Based on their t-KCL scores, the participants were classified as robust (0–3 points), pre-frail (4–7 points), and frail (≥8 points). The deaths of those aged 75–89 years who had completed the KCL were investigated. Information on deaths was obtained from local authorities. Statistics were examined for the risk of robust, pre-frail, and frail mortality using a Cox proportional hazards model with age and gender as covariates for the 75–79, 80–84, and 85–89 age groups. Results: Of the 7,924 participants, 3,423 (75–79 years: 1,990, 80–84 years: 1,059, 85–89 years: 374) were ultimately eligible for the study. Of these, 2,450 (75–79 years: 1,238, 80–84 years: 861, 85–89 years: 351) died over the 15-year study period. Hazard ratios for death in frailty as determined by the t-KCL score were 1.337 (95% confidence interval [CI], 1.162–1.540) for the pre-frail group and 2.012 (95% CI, 1.7756–2.305) for the frail group at 75–79 years, respectively, compared with the robust group; 1.511 (95% CI, 1.271–1.797) at 80–84 years only in the frail group; and 1.567 (95% CI, 1.140–2.154) at 85–89 years, also in the frail group. Discussion: The relationship between frailty and mortality weakens after age 80. The results suggest that factors other than frailty may have a stronger influence on mortality risk after the age of 80.

Associations between long-term care-service use and service- or care-need level progression: a nationwide cohort study using the Japanese Long-Term Care Insurance Claims database

BackgroundThe effectiveness of the long-term care service in Japan has been unclear, and most of the relevant studies of this service have been limited to a single region and relatively small samples, necessitating large-scale studies. We examined the associations between long-term care service use and the service/care-need level progression at the national scale in Japan.MethodsWe conducted a nationwide retrospective cohort study using data from the Japanese Long-Term Care Insurance Claims database. Individuals aged ≥ 65 years and newly certified as being at the support-need level 1 or 2 or the care-need level 1 between April 2012 and March 2013 were included. We first conducted 1:1 propensity score matching and then examined the associations between service use and the progression in support-need or care-need levels by using Kaplan–Meier survival curves and log-rank tests.ResultsThe final sample consisted of 332,766 individuals. We observed that service use was associated with a faster decline in the support/care-need level, although the differences in the subjects' survival rate diminished; the log-rank test showed significance (p < 0.001). When stratified for urban–rural classifications or regions of Japan, the results were similar to the primary analysis in all of the stratified groups, and no clear regional variations were observed.ConclusionWe did not observe a clear beneficial effect of receiving long-term care in Japan. Our results suggest that Japan's current long-term care service may not be effective for the recipients of these services. Considering that the system is becoming a financial burden, a re-examination of the service to provide more cost-effective care may be advisable.

Regional disparities in Dementia-free Life Expectancy in Japan: An ecological study, using the Japanese long-term care insurance claims database.

The number of people with dementia increases in an aging society; therefore, promoting policies for dementia throughout the community is crucial to creating a dementia-friendly society. Understanding the status of older adults with dementia in each region of Japan will be a helpful indicator. We calculated Dementia-free Life Expectancy and aimed to examine regional disparities and their associated factors. We calculated Dementia-free Life Expectancy and Life Expectancy with Dementia for each secondary medical area in Japan based on the Degree of Independence in Daily Living for the Demented Elderly, using data extracted from the Japanese long-term care insurance claims database. We then conducted a partial least squares regression analysis, the objective variables being Dementia-free Life Expectancy and Life Expectancy with Dementia for both sexes at age 65, and explanatory regional-level variables included demographic, socioeconomic, and healthcare resources variables. The mean estimated regional-level Dementia-free Life Expectancy at age 65 was 17.33 years (95% confidence interval [CI] 17.27-17.38) for males and 20.05 years (95% CI 19.99-20.11) for females. Three latent components identified by partial least squares regression analysis represented urbanicity, socioeconomic conditions, and health services-related factors of the secondary medical areas. The second component explained the most variation in Dementia-free Life Expectancy of the three, indicating that higher socioeconomic status was associated with longer Dementia-free Life Expectancy. There were regional disparities in secondary medical area level Dementia-free Life Expectancy. Our results suggest that socioeconomic conditions are more related to Dementia-free Life Expectancy than urbanicity and health services-related factors.

Leg skeletal muscle mass asymmetry is independently associated with gait speed in older adults requiring long-term care.

Decreased gait speed in older adults has been associated with incident disability, cognitive impairment, institutionalization, falls, deterioration in level of care, and mortality. Gait speed has been reported to be related to leg asymmetry. However, the relationship between gait speed and leg skeletal muscle mass asymmetry in older adults requiring long-term care has not been clarified. In this study, we examined the association between gait speed and leg skeletal muscle mass asymmetry and the cutoff values of leg skeletal muscle mass asymmetry that may affect gait speed. The asymmetry index of leg skeletal muscle mass was measured in 230 older adults under the Japanese long-term care insurance system using bioelectrical impedance analysis. This cross-sectional study used multiple regression analysis and receiver operating characteristic (ROC) curve analysis to determine the relationship between gait speed and the asymmetry index of leg skeletal muscle mass. Multiple regression analysis revealed that the asymmetry index of leg skeletal muscle mass (β = -0.19, P = 0.002, R2 = 0.261) was independently and significantly associated with gait speed. Furthermore, ROC analysis showed that the cutoff value of the asymmetry index of leg skeletal muscle mass that identified reduced gait speed (<1.0 m/s) was 3.02% (Area under the curve = 0.62, sensitivity 47.3%, specificity 81.0%, P = 0.014). The asymmetry index of leg skeletal muscle mass was associated with gait speed in older adults requiring long-term care. Future assessment and interventions directed towards symmetry of leg skeletal muscle mass may help to improve gait speed in older adults. Geriatr Gerontol Int 2023; 23: 371-375.

Prediction tool for disability progression and mortality in older adults eligible for Japanese long-term care insurance: Koriyama study.

This study aims to create a simple model for predicting disability progression and death among older adults with Japanese long-term care insurance certification. This retrospective study analyzed the anonymized data provided by Koriyama City. The participants were 7706 older adults who were initially certified to be support levels 1 and 2 or care levels 1 and 2 for the purpose of obtaining Japanese long-term care insurance. The results of the certification questionnaire at the initial survey stage were used to create decision tree models intended to predict whether disability progression and death would occur within 1 year. In support levels 1 and 2, among those who scored both "daily decision making" item as other than "possible" and the "taking drugs" item as other than "independent," 64.7% had an adverse outcome. In care levels 1 and 2, among those who scored both the "shopping" item as "totally dependent" and the "defecation" item as other than "independent," 58.6% had an adverse outcome. The accuracy of classification of the decision trees were 61.1% in support levels 1and 2, and 61.7% in care levels 1 and 2. The overall accuracy of the decision tree is low, making it impractical to use it for all subjects. Nevertheless, based on the results of the 2 assessments in this study, the process of identifying a particular group of older adults at a high risk of an increased need for long-term care or possible death within a year is very simple and useful.

Temporal change in the association between life satisfaction and functional decline with gender differences: an age-specific prospective cohort study.

Although life satisfaction (LS) has been shown to predict mortality, research studying the relationship between LS and functional decline is scarce. This study examined the association between LS and functional decline across four time points in young-old Japanese adults. We analysed 1,899 community-dwelling 65-year-olds in this age-specific cohort study conducted between 2000 and 2005. The Life Satisfaction Index K was used to evaluate LS and was classified into quartiles. Functional decline was determined using the Japanese Long-Term Care Insurance (LTCI) system: 1) mild disability; 2) severe disability; 3) all-cause mortality; 4) mild or severe disability; 5) severe disability or death; 6) mild or severe disability, or death. Adjusted hazard ratios (HR) with 95% confidence intervals (CI) were calculated using the Cox proportional hazard model. The analyses were conducted in the 8th, 10th, 12th, and 14th years to assess the effect of LS on functional decline across time points. The impact of LS gradually weakened over time. In the 8th year (aged 72-73), a higher LS was associated with a lower risk of mild or severe disability among the women participants (adjusted HR [95% CI] = 0.30 [0.11-0.81]). However, the effect disappeared gradually (adjusted HR [95% CI] = 0.55 [0.27-1.14]) in the 10th year (aged 74-75), 0.72 (0.41-1.26) in the 12th year (aged 76-77), and 0.68 (0.41-1.14) in the 14th year (aged 78-79). This trend continued in severe disability or death (adjusted HR [95% CI] = 0.24 [0.06-0.70], 0.31 [0.11-0.76], 0.57 [0.28-1.14], and 0.60 [0.32-1.12]) and mild or severe disability, or death (adjusted HR [95% CI] = 0.30 [0.14-0.68], 0.46 [0.24-0.87], 0.67 [0.41-1.10], and 0.65 [0.42-1.02]) in the 8th, 10th, 12th, and 14th years, respectively. No statistically significant association was found among men at any time points or in any classification of outcomes. Higher LS scores in 65-year-old women were associated with a lower risk for functional decline in any combination of mild disability, severe disability, or death. Additionally, the effect of LS was observed to weaken over time. This is not an intervention survey and does not require registration.

Increased care-need in older long-term care insurance users after the 2018 Japan Floods: a retrospective cohort study based on the Japanese long-term care insurance claims.

Level of care-need (LOC) is an indicator of elderly person's disability level and is officially used to determine the care services provided in Japan's long-term care insurance (LTCI) system. The 2018 Japan Floods, which struck western Japan in July 2018, were the country's second largest water disaster. This study determined the extent to which the disaster affected the LOC of victims and compared it with that of non-victims. This is a retrospective cohort study, based on the Japanese long-term care insurance claims from two months before (May 2018) to five months after the disaster (December 2018) in Hiroshima, Okayama, and Ehime prefectures, which were the most severely damaged areas in the country. A code indicating victim status, certified by a residential municipality, was used to distinguish between victims and non-victims. Those aged 64 years or younger, those who had the most severe LOC before the disaster, and those whose LOC increased even before the disaster were excluded. The primary endpoint was the augmentation of pre-disaster LOC after the disaster, which was evaluated using the survival time analysis. Age, gender, and type of care service were used as covariates. Of the total 193,723 participants, 1,407 (0.7%) were certified disaster victims. Five months after the disaster, 135 (9.6%) of victims and 14,817 (7.7%) of non-victims experienced the rise of LOC. The victim group was significantly more likely to experience an augmentation of LOC than the non-victim group (adjusted hazard ratio 1.24; 95% confidence interval 1.06-1.45). Older people who were affected by the disaster needed more care than before and the degree of care-need increase was substantially more than non-victims. The result suggests that natural disasters generate more demand for care services among the older people, and incur more resources and cost for society than before.

COSTS OF DEMENTIA CARE AND EARLY-STAGE PREVENTIVE NURSING: A COMPARATIVE BIG DATA STUDY IN OSAKA

Abstract Data show a substantial increase in the costs of dementia care nationally and globally. We assessed the factors increasing financial pressure, and found an association between the costs and the severity of dementia. We suggest that early diagnosis and preventive nursing care can reduce the deterioration associated with dementia, and therefore the overall costs of dementia care. The purpose of this study was to determine the relationship between the costs of dementia care and early-stage preventive nursing care in a sample of people with dementia aged 65 to 85 years, using the Medical Care Insurance and Osaka Prefecture Long-Term Care Insurance Database (N = 17973). We found that early care might have a significant effect on formal care costs in the early period of dementia but did not influence the medical care costs of dementia. During the first 5 years, the long-term care costs of people with dementia with an initial care level of Support 1/2 (one type of care level of Japanese long-term care insurance system, and the participants receive preventive services) were $4,389, while people with an initial care level of Care 1/2 (the other type of care level, and the participants receive nursing services) were $12,333. About 20% of people who received preventive care recovered, suggesting that preventive nursing care can restore the ability of people with early-stage dementia. This might be the reason for the reduction in long-term care costs. This research provides a basis for supporting preventive nursing care and extending healthy lifespans.

Differential Associations of Frailty with the Incidence of Mild and Severe Disabilities in Older Adults: A 3-Year Cohort Study.

Frailty is associated with the incidence of disability in older adults; however, few studies have investigated differences in the association of frailty with mild and severe disabilities according to Japanese long-term care insurance certification. This study separately investigated the associations between frailty and the incidence of mild and severe disabilities. This 3-year retrospective cohort study included community-dwelling adults in Okayama City aged ≥65 years. We assessed frailty status using the Kihon Checklist and defined the outcomes as mild and severe disabilities according to long-term care insurance certifications. We applied multinomial logistic regression analysis to investigate the association between frailty and the incidence of mild and severe disabilities. The analysis included a total of 36,043 participants. For mild disability, the odds ratios (ORs) comparing frail to robust and prefrail to robust were 3.85 (95% confidence interval [CI], 3.36-4.42) and 1.82 (95% CI, 1.58-2.10), respectively. Similarly, the corresponding ORs for severe disability were 4.35 (95% CI, 3.55-5.34) and 1.78 (95% CI, 1.43-2.21), respectively. In the age-stratified analysis of mild disability, the pre-old group (aged 65-74 years) with frail showed a higher association than the old-age group (aged ≥75 years) with frail. Regarding severe disability, the older group with frailty showed a higher association than the pre-old group with frailty. The results showed that both prefrail and frail were associated with the incidence of mild and severe disabilities, with different patterns of association between the pre-old and old age groups.

Comparison between the Chief Care Manager and the Normal Care Manager on Hospitalization and Discharge Coordination Activities in Japan: An Online Cross-Sectional Study of Care Managers in Aichi Prefecture.

The Japanese long-term care insurance system came into operation in the year 2000 and the chief care manager certification system was established in 2006 to improve the quality of care management. Certified chief care managers are expected to perform the role of a specialist. The purpose of this study was to determine the impact of the chief care manager certificate in coordination with hospitals. In this online cross-sectional survey, responses were obtained from 448 care managers engaged in long-term care activities with all in-home long-term care support providers. Among these 448 care managers, 301 had the chief care manager certificate. Of these care managers, ≥90% regularly asked their patients about their “values” and ≥80% provided their patients with hospitalization and discharge support. Of the care managers who provided their patients with hospitalization support, 80% provided the hospitals with information regarding patient “values” at the time of hospitalization, and 50% provided the hospitals with information regarding patient “values” and information. The chief care manager certificate had positive effects on confidence in hospitalization and discharge support. However, no significant difference was observed between the activities of chief and normal care managers in terms of hospitalization and discharge support.
