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.

Association Between Malnutrition and Food Texture Levels in Integrated Facilities for Medical and Long-Term Care.

This study aims to investigate the association between malnutrition using the global consensus criteria and food texture levels in residents of Integrated Facilities for Medical and Long-Term Care (IFMLCs), which are new long-term care insurance facilities in Japan. This single-center study had a retrospective cross-sectional design. The study was conducted from November 1 to 30, 2021, and the study participants were residents admitted to an IFMLC during the study period. Malnutrition was diagnosed according to the Global Leadership Initiative on Malnutrition (GLIM) criteria. Food texture levels consumed by patients at admission were categorized based on the International Dysphagia Diet Standardization Initiative (IDDSI) framework. Multivariate logistic regression models were used to determine the association between the food texture levels consumed and malnutrition. A total of 98 older residents were analyzed in this study. The median age of the participants was 88 years, and 68 (69%) female participants were included. The IDDSI framework levels were 24% in levels 7 and 6 and 26% in levels 5 and 4. A significant difference in the prevalence of low BMI, reduced muscle mass, and reduced food intake or assimilation was noted between IDDSI framework levels 4 and 7. Multivariate logistic regression analysis was performed for malnutrition, adjusting simultaneously for potential confounders. IDDSI level 4 (odds ratio, 5.074; 95% confidence interval, 1.059-28.092; p=0.042) consumption was independently associated with malnutrition. The consumption of lower food texture levels categorized using the IDDSI framework was associated with a higher malnutrition prevalence in IFMLC residents.

Trajectories of medical care expenditure in the last year of life associated with long-term care utilization in frail older adults: A retrospective cohort study.

Medical care and long-term care utilization in the last year of life of frail older adults could be a key indicator of their quality of life. This study aimed to identify the medical care expenditure (MCE) trajectories in the last year of life of frail older adults by investigating the association between MCE and long-term care utilization in each trajectory. The retrospective cohort study of three municipalities in Japan included 405 decedents (median age at death, 85 years; 189 women [46.7%]) from a cohort of 1,658 frail older adults aged ≥65 years who were newly certified as support level in the long-term care insurance program from April 2012 to March 2013. This study used long-term care and medical insurance claim data from April 2012 to March 2017. The primary outcome was MCE over the 12 months preceding death. Group-based trajectory modeling was conducted to identify the MCE trajectories. A mixed-effect model was employed to examine the association between long-term care utilization and MCE in each trajectory. Participants were stratified into four groups based on MCE trajectories over the 12 months preceding death as follows: rising (n = 159, 39.3%), persistently high (n = 143, 35.3%), minimal (n = 56, 13.8%), and descending (n = 47, 11.6%) groups. Home-based long-term care utilization was associated with increased MCE in the descending trajectory (coefficient, 1.48; 95% confidence interval [CI], 1.35-1.62). Facility-based long-term care utilization was associated with reduced MCE in the rising trajectory (coefficient, 0.59; 95% CI, 0.50-0.69). Both home-based (coefficient, 0.92; 95% CI, 0.85-0.99) and facility-based (coefficient; 0.53; 95% CI, 0.41-0.63) long-term care utilization were associated with reduced MCE in the persistently high trajectory. These findings may facilitate the integration of medical and long-term care models at the end of life in frail older adults.

The impact of long-term care insurance on family care for older adults: The mediating role of intergenerational financial support.

Rapid population aging has been placing heavy tolls on Chinese family caregivers. Previous empirical evidence from multiple countries have shown that establishing national long-term care insurance was effective in reducing family care burdens. Utilizing data from the China Health and Retirement Longitudinal Study (CHARLS) wave 2011 to 2018, this study examined the effects of implementing the pilot long-term care insurance program on family care received by the Chinese older adults, by using a time-varying Difference-in-Differences (DID) method. The results showed that: (1) the implementation of the pilot long-term care insurance program has led to a 17.2% decline in general for family care received by the Chinese older adults. (2) The effect of participating in the pilot program on family care received differed by respondent's household registration, health status, marital status, and possesion of retirement pension, and were specifically pronounced among those who were urban residents, having spouse, living with disabilities, and living with no retirement pension. (3) Further results from the mechanism analyses showed that the pilot long-term care insurance program decreased the level of family care by reducing the dual intergenerational financial support between older adults and their adult children. (4) Although participating in the pilot program decreased older adult's dependence on their adult children, their physical and mental health status were not negatively affected. This study contributes to the existing literature by evaluating the effects of implementing the pilot long-term care insurance program on family care received by the Chinese older adults, and lends supports to the previous studies that participating in long-term care insurance significantly reduces old adults' demand for family care, but not in sacrifice of their physical and mental well-being.

Depression and the risk of dementia and all-cause mortality among Japanese older adults: A 9-year longitudinal study from JAGES.

This study aims to investigate the association and dose-response relationship between depression, dementia, and all-cause mortality based on a national cohort study of elderly people in Japan. We conducted a longitudinal study of 44,546 participants aged ≥65 from 2010-2019 Japanese Gerontological Evaluation Study (JAGES). The Geriatric Depression Scale (GDS-15) was used to assess depressive symptoms and the long-term care insurance (LTCI) was used to assess dementia. Fine-gray models and Cox proportional hazard models were used to explore the effect of depression severity on the incidence of dementia and all-cause mortality, respectively. Causal mediation analysis (CMA) to explore the extent of association between dementia-mediated depression and all-cause mortality. We found that both minor and major depressive symptoms were associated with the increased cumulative incidence of dementia and all-cause mortality, especially major depressive symptoms (P < 0.001). The multivariable-adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for dementia were 1.25 (1.19-1.32) for minor depressive symptoms and 1.42 (1.30-1.54) for major depressive symptoms in comparison to non-depression; P for trend < 0.001. The multivariable-adjusted HRs and 95% CIs for all-cause mortality were 1.27 (1.21-1.33) for minor depressive symptoms and 1.51 (1.41-1.62) for major depressive symptoms in comparison to non-depression; P for trend < 0.001. Depression has a stronger impact on dementia and all-cause mortality among the younger group. In addition, dementia significantly mediated the association between depression and all-cause mortality. Interventions targeting major depression may be an effective strategy for preventing dementia and premature death.

Informal and formal long-term care utilization and unmet needs in Europe: examining socioeconomic disparities and the role of social policies for older adults.

The rising number of older adults with limitations in their daily activities has major implications for the demands placed on long-term care (LTC) systems across Europe. Recognizing that demand can be both constrained and encouraged by individual and country-specific factors, this study explains the uptake of home-based long-term care in 18 European countries with LTC policies and pension generosity along with individual factors such as socioeconomic status. Using data from the Survey of Health, Ageing and Retirement in Europe conducted in 2019, we apply a two-part multilevel model to assess if disparities in use of LTC are driven by disparities in needs or disparities in use of care when in need. While individual characteristics largely affect the use of care through its association with disparities in need, country-level characteristics are important for the use of care when in need. In particular, the better health of wealthier and more educated individuals makes them less likely to use any type of home-based personal care. At the country level, results show that the absence of a means-tested benefit scheme and the availability of cash-for-care benefits (as opposed to in-kind) are strongly associated with the use of formal care, whether it is mixed (with informal care) or exclusive. LTC policies are, however, shown to be insufficient to significantly reduce unmet needs for personal care. Conversely, generous pensions are significantly associated with lower unmet needs, underscoring the importance of considering the likely adverse effects of future pension reforms.

Association Between Oral Malodor and Dementia: An 11-Year Follow-Up Study inJapan.

As infrequent social interaction is a potential risk of dementia, oral malodor may increase the risk of dementia, including Alzheimer's disease. This study investigated the association between malodor and dementia. We used the Japan Public Health Center-based Prospective Study data obtained at Yokote City. A total of 1,493 individuals aged 56 to 75 years underwent a dental examination and self-reported survey from May 2005 to January 2006. Follow-up for the onset of dementia was conducted using long-term care insurance data from 2006 to 2016. Hazard ratios of oral malodor on dementia were estimated by the Cox proportional hazards model. The inverse probability-weighted Cox model was used as a sensitivity analysis. The study comprised 1493 participants (53.6% women) with a mean age of 65.6 (SD = 5.8) years old; at the end of the follow-up, 6.4% (n = 96) developed dementia, and the percentage was 20.7 in severe malodor group. Throughout 15274.133 person-years of follow-up, the average incidence rate for the onset of dementia per 1000 person-years was 6.29. The highest incidence rate was seen in participants with severe malodor (22.4 per 1000 person-years). After adjusting for confounders, compared to those with no malodor, there was a 3.8 (95% confidence interval: 1.5 to 9.4) times greater hazard of developing dementia in participants with severe malodor. The inverse probability weighted Cox model confirmed the same trend with an adjusted marginal hazard ratio of 4.4 (1.2 to 16.4). A significant association between oral malodor and the onset of dementia exists.

Self-Reported Sleep Duration and Bedtime Are Associated with Dementia Risk in Community-Dwelling People Aged 40-74 Years: The Murakami Cohort Study.

Sleep is a potentially modifiable factor associated with dementia, including Alzheimer's disease, but current evidence supporting this is insufficient. This study aimed to determine whether sleep duration and bedtime patterns are associated with the risk of dementia among middle-aged and older people. This cohort study had an eight-year follow-up period. Participants were 13,601 community-dwelling people aged 40-74 years living in Murakami (Niigata, Japan). Data were collected using a self-administered questionnaire. Predictors were self-reported sleep duration and bedtime, and the outcome was newly-diagnosed dementia determined using the long-term care insurance database. Covariates were demographic characteristics, body mass index, smoking, alcohol consumption, total physical activity, insomnia symptoms, disease history, and either bedtime or sleep duration. Cox proportional hazard models were used to calculate hazard ratios (HRs). The mean age of participants at baseline was 59.2 years. Over a mean follow-up period of 8.0 years, 319 cases of dementia were observed. A long self-reported sleep duration relative to the reference sleep duration (7 hours) was associated with increased dementia risk, with the "8 hours" group (adjusted HR = 1.30, 95% CI:0.99-1.73) and "≥9 hours" group (adjusted HR = 1.46, 95% CI:1.00-2.15) having an increased risk (marginally significant) relative to the reference group. Early bedtime was associated with increased dementia risk (adjusted p for trend = 0.0010), with the "21 : 00 or earlier" group (adjusted HR = 1.61, 95% CI:1.14-2.28) having an increased risk relative to the reference ("23 : 00"). A long self-reported sleep duration and early bedtime are both associated with increased dementia risk in middle-aged and older people.

Research on the income and expenditure forecast of long-term care insurance fund in Shihezi City based on community care.

This study forecasts the income and expenditures of the long-term care insurance fund, provides a basis for formulating the raising standard of the long-term care insurance fund, and explores the measures to improve the pilot work of long-term care insurance. By using the exponential smoothing and ARIMA models to forecast the income and expenditure of the old-age care insurance fund in 2022, the problems existing in the operation of the long-term care insurance fund are discussed. In 2022, the income of the old-age insurance fund was 28.8934 million yuan, and the fund compensation expenditure was 28.4070 million yuan, with a slight balance of the fund. The highest relative errors of income and expenditure forecast models are -2.03% and - 2.76%, respectively. According to the results of fund expenditure, the annual financing standard should be 132.93 yuan/person, and the individual financing standard should be 66.47 yuan/person. Through the integration of personal payment, welfare, sports lottery public welfare income, social donations, and other ways, we can gradually establish a multi-channel risk-sharing financing. We will appropriately raise the standard for individual financing and the annual contribution standard for individuals from 50 yuan to 66.47 yuan. This will promote sustainable development of long-term insurance system.

Long-term care insurance coverage and labor force participation of older people: Evidence from China

Many scholars attribute the slowdown of economic growth to population aging and its negative impact on the size of the labor force. Meanwhile, government programs targeting an aging society can generate work disincentives. This paper studies the unintended labor market effects of Long-term Care Insurance (LTCI) among people of older age by exploiting the launch of the LTCI program in China. We find that policy-covered older adults decreased labor market engagement, significantly increasing the probability of exiting the labor market completely or not working full-time. We also document more substantial effects among those with low income, poor health, advanced age, and few children. The forgone wages of older adults account for >0.25% of GDP. These findings have policy implications for countries “growing old before getting rich.”

Does income matter for the policy effect of public long-term care insurance on informal care use in China? A quasi-experimental study.

Since 2016, the Chinese government has been piloting a public long-term care insurance (LTCI) scheme. This study examined whether the LTCI scheme reduced the use of informal care and how this has varied across income groups. We used data from the 2011, 2014, and 2018 waves of Chinese Longitudinal Healthy Longevity Survey, focusing on community-dwelling older adults aged 65 years and older. We used staggered difference-in-differences analyses with propensity score matching to examine the effects of the policy. The LTCI scheme reduced the probability and intensity of informal care use by 5.7% (p < .05) and 17.4% (p < .05), respectively. The policy impact was limited to older people in the middle-income group, reducing the probability and intensity of informal care use by 15.6% (p < .001) and 43.1% (p < .05), respectively. We did not find a statistically significant policy effect for older adults with high or low incomes. The LTCI scheme had different effects on reducing the informal care burden for family caregivers by income level. We suggest that the scheme should entitle people with low incomes to a preferential co-payment rate, thereby enhancing their access to formal care.

Long-run consequences of informal elderly care and implications of public long-term care insurance

We estimate a dynamic structural model of labor supply, retirement, and informal caregiving to study short and long-term costs of informal caregiving in Germany. Incorporating labor market frictions and the German tax and benefit system, we find that in the absence of Germany’s public long-term insurance scheme, informal elderly care has adverse and persistent effects on labor market outcomes and, thus, negatively affects lifetime earnings and future pension benefits. These consequences of caregiving are heterogeneous and depend on age, previous earnings, and institutional regulations. Policy simulations suggest that while public long-term care insurance policies are fiscally costly and induce negative labor market effects, they can largely offset the personal costs of caregiving and increase welfare, especially for low-income individuals.

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...

Changes in physical activity during the year after the Great East Japan Earthquake and future frailty in older survivors.

This study examines whether changes in physical activity (PA) during the first year after the Great East Japan Earthquake and Tsunami (2011-2012) contributed to preventing the onset of future frailty among older survivors of the disaster. This study tracked 2561 physically active Japanese survivors aged ≥ 65 years (43.6% men; mean age 72.9 years) who had completed self-administered questionnaires in 2011 and 2012. PA levels for participants were classified into four categories based on ≥23 and <23 metabolic equivalent hours/week in 2011 and 2012: "consistently low," "decreasing," "increasing," and "consistently high." Frailty was defined as a Kihon Checklist score ≥ 5, which is used in the long-term care insurance system in Japan. Hazard ratios were calculated for the onset of frailty using a Cox proportional hazards model that fitted the proportional sub-distribution hazards regression model with weights for competing risks of death. From 2012 to 2018, 283 men and 490 women developed frailty. Men with consistently high or increasing PA during the first year after the disaster had a lower risk of frailty. Furthermore, even increasing PA by walking for just 30 min/day prevented future frailty in men; however, this association between a change in PA and the decreased risk of frailty was not observed in women. Older men who remained physically active or resumed PA at an early stage and at a low intensity, even after being physically inactive owing to the disaster, were able to prevent future frailty.

Older adults preferences for long-term caregivers in China: a discrete choice experiment

ObjectiveUnderstanding the preferences of old-age adults for their long-term caregivers can improve person-centred health care and the quality of long-term care (LTC). This study examines Chinese older adults’ preferences for long-term caregivers. Study designThis is a cross-sectional study. MethodsA national representative discrete choice experiment (DCE) surveyed 2031 adults aged 50–70 across 12 provinces in China. Each DCE scenario described five attributes: type of caregivers, place of LTC, contents of LTC, out-of-pocket payments, and quality of life (QoL). Preferences and the marginal willingness to pay (WTP) were derived using mixed-logit and latent class models. ResultsOlder adults displayed higher preferences for long-term caregivers who improve their QoL, incur lower out-of-pocket payments, and provide medical LTC services at home, with the maximum WTP of $22.832 per month. QoL was rated as the most important LTC factor, followed by the place of LTC and the type of caregivers. When the level of QoL improved from poor to good, respondents would be willing to pay $18.375 per month more (95% confidence interval: 16.858 to 20.137), and the uptake rate increased by 76.47%. There was preference heterogeneity among older people with different sex, education, family size, and knowledge of LTC insurance. ConclusionQoL was the most important factor in older Chinese adults' preference for caregivers. Home care and medical care from formal caregivers was preferred by older adults. We recommend training family caregivers, raising older people's awareness of LTC insurance, and guiding policymakers in developing people-oriented LTC and a multi-level LTC system.

Difficulties and Solutions in Caring for Cognitive Disorders in Elderly People with Dementia from the Perspective of Social-ecological System Theory

With the deepening of population aging, the increasing population of cognitively impaired older adults in China has put forward an urgent demand for professional cognitive care. In the context of long-term care insurance policy, this paper will take R agency as an example and construct an analysis framework based on the social-ecological system theory at three levels: micro-system, meso-system, and macro-system. It will analyze the physiology and psychology of dementia elderly from inside to outside, how the sentinel care agency collaborates with the sentinel assessment agency, family, and community, how the LTCI policy support and financial support affect the cognitive intervention for cognitively impaired elderly, to promote the healthy operation of the care ecosystem, analyze the dilemma, summarise and put forward the optimization strategy, and provide the experience of providing care services for other aged care service agencies.

Dose-response associations between physical activity and sedentary time with functional disability in older adults with or without frailty: a prospective cohort study.

Evidence regarding the dose-response curve shapes of physical activity (PA) and sedentary time (ST) in older adults with functional disability (FD) is extremely limited. Moreover, these associations may differ depending on with/without frailty. We examined the dose-response associations between moderate-to-vigorous PA (MVPA) and ST with FD among older adults with/without frailty. We included 7,480 initially nondisabled adults (3,795 men and 3,685 women) aged 65-84 years in Ota City, Tokyo, Japan. MVPA and ST were evaluated using the International Physical Activity Questionnaire-Short Form. FD was prospectively identified using a nationally unified database of the long-term care insurance system. Frailty was determined using Check-List 15, validated against Fried's frailty criteria. Multivariate-adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) of MVPA and ST for FD were calculated, and dose-response curves were examined using restricted cubic splines. During 3.6 years of follow-up, 1,001 (13.4%) participants had FD. Among all participants, compared with no MVPA, the HRs for FD reduced linearly up to approximately 2000 metabolic equivalents (METs)■min/week of MVPA, and the lowest HR (HR: 0.61, 95% CI: 0.51-0.74) was reached at around 3,000-4,000 METs■min/week. Although the shape of this association was consistent regardless of with/without frailty, the magnitude of the association tended to be stronger in frail older adults than in non-frail older adults. Compared with those for the median (300 min/day) of ST, the HRs for FD increased linearly as ST reached approximately 600 min/day or more, independent of MVPA, with a maximum HR of 1.31 (95% CI: 1.01-1.71) for 1,080 min/day among all participants. This association was more pronounced among non-frail older adults but not statistically significant among frail older adults. Higher MVPA levels consistently reduced the incidence of FD regardless of frailty in a significant inverse nonlinear dose-response manner. A significant positive nonlinear dose-response association between ST and FD risk was identified among non-frail older adults but not among frail older adults. Increasing MVPA and reducing prolonged ST are important for preventing FD among non-frail older adults. However, reducing ST alone may be insufficient; increasing MVPA, even if by only small increments, is highly recommended for frail older adults.

Treatment strategies for pelvic organ prolapse and postoperative outcomes in older women with long-term care needs: A population-based retrospective cohort study.

The study aimed to investigate treatment options for older women with pelvic organ prolapse (POP) and postoperative outcomes based on their long-term care (LTC) status. We used the medical and LTC insurance claims databases of Tochigi Prefecture in Japan, covering 2014 to 2019. We included women 65 years and older with POP and evaluated their care status and treatment, excluding women with an observation period <6 months. Among women with a postsurgical interval ≥6 months, we compared care level changes and deaths within 6 months and complications within 1 month postoperatively between those with and without LTC using Fisher exact test. We identified 3406 eligible women. Of the 447 women with LTC and 2959 women without LTC, 16 (3.6%) and 415 (14.0%), respectively, underwent surgery. Among 393 women with a postsurgical interval ≥6 months, 19 (4.8%) required LTC at surgery. Two of the 19 women with LTC (10.5%) and eight of 374 women without LTC (2.1%) experienced worsening care-needs level. No deaths were recorded. Urinary tract infection (UTI) was significantly more frequent in women with LTC than in women without LTC (36.8% vs 8.6%). Other complications were rare in both groups. The proportion of patients who underwent surgery for POP was lower in women with LTC than in women without LTC. Postoperative UTI was common and 11% had a worsening care-needs level postoperatively, whereas other complications were infrequent. Further detailed studies would contribute to providing optimal treatment to enhance patients' quality of life.
