Development of a weighted scoring model for social activities to predict disability incidents among older Japanese adults

BackgroundSocial activities contribute to health improvements in older adults, but methods for evaluating these activities are not yet established. We developed a scoring model for social activity, weighted by specific activities, to assess the association between disability incidence in older adults and social activities. MethodsData were obtained from Japan's National Center for Geriatrics and Gerontology Study of Geriatric Syndromes (NCGG-SGS). Social activity was evaluated across 16 domains. Disability was determined using data extracted from Japan's long-term care insurance system. ResultsData from 4998 older adults were analyzed; among them, 422 (8.4 %) developed a disability within 35 months (Interquartile range: 32-39). The Cox proportional hazards model was used to assess 16 domains of social activity. The results yielded risk factors for disability incidence in six social activity domains: work, travel, hobbies, babysitting, family caregiving, and events. The coefficients for these activities were assigned weights of 3, 3, 2, 1, 1, and 1, respectively. The weighted social activity scoring model significantly improved the ability to predict disability incidence when the number of social activities in which individuals participated was considered (social activity score: area under the curve [AUC] 0.691, 95 % confidence interval [CI] 0.664–0.717; number of social activities: AUC 0.681, 95 % CI 0.654–0.707, P = 0.042). ConclusionsThe composite score derived from the weighted social activity scoring model serves as a valuable tool due to its enhanced predictability, which complements established background factors associated with the incidence of disability in older adults.

Services in public long-term care insurance in Japan.

In Japan, a public long-term care insurance system was launched in 2000. Residents can receive long-term care according to their care needs, as determined by a nationally standardized certification system. The present report describes the details of the long-term care services covered by public insurance. The Long-Term Care Insurance Act categorizes services into three major types: in-home, nursing-home, and community-based long-term care services. In-home care services include visiting, commuting, short-stay, and other services. Welfare, health, and medical facilities provide nursing-home care services for the elderly. Community-based care services were categorized into visiting, commuting, nursing-home, and composite services.

Association between decreased neck circumference and impaired activities of daily living among older adults in long-term care.

Assessment interventions for the decline of activities of daily living (ADLs) in older adults are crucial, as ADL decline increases hospitalization duration and mortality risk. Decreased neck circumference may result in various physical dysfunctions, including malnutrition. However, the association between neck circumference and ADLs has not been fully clarified. This study aimed to determine the association between decreased neck circumference and ADLs in older adults requiring long-term care. The study included 152 older adults deemed to require support or care under Japan's long-term care insurance system. Neck circumference was measured just below the thyroid cartilage with a measuring tape. The Barthel index was used to evaluate ADLs, and skeletal muscle mass and nutritional status were assessed by bioelectrical impedance analysis instruments. A multivariate analysis was conducted to investigate the association between neck circumference and ADLs. Neck circumference demonstrated a significant inverse correlation with age and a significant positive correlation with body mass index, skeletal muscle mass index, phase angle, and Barthel index. In the multivariate analysis, ADLs was significantly associated with neck circumference (odds ratio [OR] = 0.51, P = 0.002) and phase angle (OR = 0.04, P < 0.001). Neck circumference is associated with age, skeletal muscle mass, and nutritional status. Furthermore, a decrease in neck circumferenceis suggested as an independent risk factor for ADL decline in older adults requiring long-term care. Geriatr Gerontol Int 2023; 23: 906-911.

Rapid weight change as a predictor of disability among community-dwelling Japanese older adults.

To fill the knowledge gap regarding weight change and the onset of disability in community-dwelling Japanese older adults, we investigated the potential effects of rapid weight change on disability risk as defined by Japan's long-term care insurance (LTCI) system. We analyzed data from a longitudinal study of 10 375 community-dwelling older Japanese adults (≥65 years) who were not LTCI needs certified at baseline and joined the study from 2002 to 2005. Weight change (percentage) was calculated by subtracting participants' weight in the previous year from that measured during a physical examination at study commencement. The five weight-change categories ranged from sizable weight loss (≤ -8.0%) to sizable weight gain (≥ +8.0%). Disability was defined according to LTCI certifications at follow-up. Hazard ratios (HRs) and 95% confidence intervals were calculated for new-onset disability using a Cox proportional hazards model that fitted the proportional subdistribution hazards regression model with weights for competing risks of death. During the mean 10.5-year follow-up, 2994 participants developed a disability. Sizable weight loss (HR [95% confidence intervals], 1.41 [1.17-1.71]) and weight loss (1.20 [1.05-1.36]) were significant predictors of disability onset. Sizable weight gain (1.45 [1.07-1.97]) corresponded to severe disability. Stratified analyses by lifestyle and initial body mass index categories revealed more pronounced associations between weight change and disability risk in the unhealthy lifestyle and below initial normal body mass index groups. Rapid and sizable weight gain could be additional criteria for disability risk in older adults. Geriatr Gerontol Int 2023; 23: 809-816.

Perceived Level of Life Enjoyment and Risk of Developing Disabling Dementia: The Japan Public Health Center-Based Study.

Life enjoyment, linked to the ability to engage pleasurably with one's environment, may be related to the risk of developing dementia. This prospective cohort study examined the association between level of life enjoyment and disabling dementia incidence among Japanese community residents. The participants were Japanese, aged 45-74 years old at 5-years follow-up, in the Japan Public Health Center-based Study (N = 38,660). Psychological conditions and other confounding variables were identified through self-administered questionnaires. Incident disabling dementia registered based on the Japan's Long-Term Care Insurance system from 2006 to 2016. Hazard ratios [95% confidence intervals] were assessed using Cox proportional hazards models. Over a median follow-up period of 9.4 years, a total of 4,642 cases of disabling dementia developed. Level of life enjoyment was inversely associated with the risk of disabling dementia: the multivariable hazard ratios were 0.75 [0.67-0.84] (p < .001) and 0.68 [0.59-0.78] (p < .001) with medium and high life enjoyment, respectively, compared to low life enjoyment. Furthermore, the association between greater life enjoyment and low risk for disabling dementia was strongest in the subgroup with low-medium mental stress. In the high mental stress group, this association was evident for poststroke disabling dementia, but not for disabling dementia without a history of stroke. A higher level of life enjoyment was associated with a lower risk of disabling dementia, particularly in the low-medium mental stress group. This finding suggests the importance of having life enjoyment by managing mental stress for reducing risk of disabling dementia.

Five-year changes of social activity and incident long-term care needs among depressed older adults: A 15-year follow up

ObjectivesTo examine the effects of changes in individual/multiple social activities between 65 and 70 years of age on incident long-term care (LTC) needs between 70 and 80 in older adults with depressive symptoms. MethodsParticipants were recruited from the New Integrated Suburban Seniority Investigation Project, an ongoing prospective cohort study. A total of 525 older adults with depressive symptoms were included. The validated 15-item Geriatric Depression Scale was used to assess depressive symptoms. A self-report questionnaire was used to measure social activities (social-related, learning, and personal). LTC needs was defined according to Japan's Long-term Care Insurance System. A competing risk model and a Laplace regression model were used to estimate the hazard ratios of LTC needs incidence and the 25th percentile difference in LTC-needs-free survival time and their 95% confidence intervals. ResultsOut of 4314 person-years of mild LTC needs, 108 individuals developed it. Participants who increased their frequency of learning activities have a lower risk of developing mild LTC needs. Increasing the frequency could also prolong LTC-needs-free survival time by approximately 2.61 years. Out of 4535 person-years for severe LTC needs, 54 individuals developed it. Participants with a continuous regular frequency of learning activities had a lower risk of developing severe LTC needs. However, the association between this frequency and LTC-needs-free survival time for severe LTC needs was insignificant in the multivariable models. ConclusionsIncreased frequency of learning activities reduced the risk of LTC needs among older adults with depressive symptoms and prolonged their LTC-needs-free survival time.

Bowel movement frequency, stool consistency, and risk of disabling dementia: a population-based cohort study in Japan

ObjectivesThis population-based study aimed to evaluate the association between bowel habits from midlife and dementia. Study designThis was a cohort study using certification records for national long-term care insurance in Japan. MethodsParticipants aged 50 to 79 years who reported bowel habits from eight districts within the Japan Public Health Center-based Prospective Study (JPHC Study) were followed from 2006 to 2016 for incident dementia. Hazard ratio (HR) and 95% confidence interval (CI) were estimated for men and women separately using Cox proportional hazards models accounting for various lifestyle factors and medical histories. ResultsAmong 19,396 men and 22,859 women, 1889 men and 2685 women were diagnosed with dementia. In men, the multivariable-adjusted HRs compared with bowel movement frequency (BMF) of once/day were 1.00 (95% CI: 0.87–1.14) for twice/day or more, 1.38 (1.16–1.65) for 5–6 times/week, 1.46 (1.18–1.80) for 3–4 times/week, and 1.79 (1.34–2.39) for <3 times/week (P for trend <0.001). In women, the corresponding HRs were 1.14 (0.998–1.31), 1.03 (0.91–1.17), 1.16 (1.01–1.33), and 1.29 (1.08–1.55) (P for trend = 0.043). Harder stool was associated with higher risk (P for trend: 0.0030 for men and 0.024 for women), with adjusted HRs compared to normal stool of 1.30 (1.08–1.57) for hard stool and 2.18 (1.23–3.85) for very hard stool in men, and 1.15 (1.002–1.32) and 1.84 (1.29–2.63) in women. ConclusionsLower BMF and harder stool were each associated with higher risk of dementia.

Effects of Caregiver's Gender or Distance Between Caregiver and Patient's Home on Home Discharge from Hospital in 285 Patients Aged ≥75 Years in Japan.

BACKGROUND Many hospitalized aged patients in Japan, the most super-aged society, are unable to be discharged home. This study was performed to clarify the factors associated with home discharge, not to a long-term care (LTC) facility or another hospital, among inpatients aged ≥75 years. MATERIAL AND METHODS A single-center prospective cohort study was performed for inpatients aged ≥75 years in a rural acute-care hospital in Japan, from November 2017 to October 2019. We divided the patients into 2 groups: those who resided at home or had died at home by 30 days after discharge, and others. We obtained data from medical charts and questionnaires given to patients and their caregivers. For each factor shown to be statistically significant by the univariable analysis, a multivariable analysis with adjustment was conducted. RESULTS In all, 285 patients agreed to participate. With adjustment by where the patient was admitted from, residing with other family members, cognitive function scores, and Barthel index, multivariable analysis using each factor identified as relevant by univariable analysis identified the following as associated with home discharge: being less informed about LTC insurance; cost of home-visit medical, nursing, or LTC services; shorter hospital stays; close proximity between patient and caregiver; main caregiver being female; and life expectancy of over 6 months (P<0.05). CONCLUSIONS Male gender and a long distance between the caregiver and patient's home significantly hindered home discharge in patients aged ≥75 years, suggesting the need to provide information regarding home-visit services under Japan's LTC insurance system for such caregivers.

A cross-sectional survey of consistent rehabilitation through long-term care insurance in Japan: a questionnaire survey.

This study was a cross-sectional study in a nationwide survey among rehabilitation staff and care recipients who completed disease-specific rehabilitation and required maintenance/community-based rehabilitation through long-term care insurance. Consistency of rehabilitation was compared using Fisher's exact tests. The concordance of the rehabilitation evaluation and treatment conducted under medical and long-term care insurance was assessed using the κ coefficient. Six hundred questionnaires from care recipients and staff were analyzed. Of the rehabilitation staff, 264 (44%) obtained rehabilitation plans from medical institutions. There was a significant difference between the responses of "referral from the same medical corporation" and "obtaining the rehabilitation plan" by Fisher's exact test (odds ratio: 3.242; P<0.001). Most rehabilitation treatments under medical insurance comprised walking or training with parallel rods/canes [498 patients (83%)], and 454 patients (76%) received stretching and range-of-motion training for the limbs and spine for long-term care insurance. Muscle strength evaluation was the most frequently conducted under medical and long-term care insurance [383 (73%) and 487 (83%), respectively]. The concordance of the evaluation and treatment content, except for disease-specific evaluation, was low (κ coefficient≤0.6). The rate of provision of rehabilitation plans was low, and evaluation and treatment content under medical and long-term care insurance was inconsistent. Our results draw attention to the need for consistent rehabilitation plans between disease-specific and maintenance/community-based rehabilitation.

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.

Impact of number of functional teeth on independence of Japanese older adults.

To examine the relationship between the number of present and functional teeth at baseline and future incidence of loss of independence. Participants were community-dwelling older individuals who participated in a comprehensive geriatric health examination conducted in Kusatsu town, Japan, between 2009 and 2015. The primary endpoint was the incidence of loss of independence among participants, defined as the first certification of long-term care insurance in Japan. The numbers of present and functional teeth at baseline were determined via an oral examination. Demographics, clinical variables (e.g., history of chronic diseases and psychosocial factors), blood nutritional markers, physical functions, and perceived masticatory function were assessed. This study included 1121 individuals, and 205 individuals suffered from loss of independence during the follow-up period. Kaplan-Meier estimates of loss of independence for participants with smaller numbers of present and functional teeth were significantly greater than for those with larger numbers of teeth. Cox proportional hazard analyses indicated that a smaller number of present teeth was not a significant risk factor after adjusting for demographic characteristics. However, the number of functional teeth was a significant risk factor after the adjustment (hazard ratio: 1.975 [1.168-3.340]). Additionally, higher hazard ratios were observed in other adjusted models, but they were not statistically significant. The number of functional teeth may be more closely related to the future incidence of loss of independence than the number of present teeth. This novel finding suggests that prosthodontic rehabilitation for tooth loss possibly prevents the future incidence of this life-event. Geriatr Gerontol Int 2022; 22: 1032-1039.

Regaining the Dignity of Eating

Inserting a nasogastric tube is a common clinical management approach to treating patients with chewing and swallowing impairments and those with choking and aspiration issues. Although guidelines recommend that these tubes should not be indwelled for more than 4-6 weeks, they are in practice sometimes indwelled for periods exceeding 36 months (Wong et al., 2019). Long-term nasogastric tube indwelling may cause clients to gradually lose the ability to chew and swallow, resulting in a decrease in the stimulation received by the brain and an increase in the incidence of dementia (Liu et al., 2019). Japan's long-term care insurance payment regulations, amended in 2021, clearly point out that successfully improving enablement, oral training, nutrition, and cognition in clients results in relatively high payments for long-term care service units (Tamiya et al., 2020). This column advocates for using inter-disciplinary collaboration to "enhance physical fitness, improve nutrition status, take care of the mouth, and then smoothly remove the nasogastric tube" in line with the abovementioned philosophy. When people eat, they initially require the coordination of their lower limb and trunk (core) muscles to support their body weight and maintain posture stability, as the upper limb muscles are critical to sending the food into the mouth. Hence, strengthening physical fitness is of primary importance. Based on the results of the medical staff's assessment, even patients with indwelled nasogastric tubes should continue eating by mouth. Providing high-protein / high-calorie texture-modified foods that meet the chewing and swallowing functional needs of clients is essential to facilitating the repair of cellular tissues. In addition, it is necessary to manage the symptoms of chewing and swallowing impairments to prevent dehydration. Clients with chewing and swallowing impairments are prone to food debris / plaque accumulation in the mouth, resulting in significant levels of bacteria breeding. Moreover, during choking, bacteria is propelled by the cough mechanism into the trachea and may cause aspiration pneumonia. Aspiration pneumonia is often managed using a nasogastric tube. Gastric acid and bacteria may migrate upwards along indwelled nasogastric tubes into the pharynx, resulting in reinfection with aspiration pneumonia. Oral hygiene is thus critical to breaking this vicious cycle. The five topics of this column were derived using the above framework. Clients who are successfully liberated of their nasogastric tubes through inter-disciplinary collaboration regain the ability to eat independently and reduce medical care expenditures, while medical professionals experience the value of their own professional existence as part of an inter-disciplinary team (Bauer et al., 2019; Cochrane et al., 2016; Magne & Vilk, 2020).

Municipal Characteristics of In-Home Death Among Care-Dependent Older Japanese Adults

The provision of in-home and community end-of-life care has emerged as an important policy issue for aging populations around the world. Despite most patients expressing the wish to die at home (as opposed to in the hospital), substantial geographic variation persists in the prevalence of in-home death at the end of life. To assess the association of municipal characteristics with variation in the place of death among care-dependent older people in Japan. In this cross-sectional study using multilevel logistic regression, analyses were performed using national claims data under Japan's long-term care insurance system. The study population included long-term care insurance beneficiaries 65 years and older who died in 2015, excluding those who died from external causes, such as unintentional injuries. Data analyses were conducted from January 1 to April 31, 2021. Predisposing, enabling, and need factors at the individual and municipal levels according to a behavioral model. The outcome was whether individuals died at home or not. This cross-sectional study analyzed 544 836 decedents (median [IQR] age, 87 [81-91] years; 300 142 [55.1%] female). The proportion of in-home deaths was 10.3%. In the multilevel null model, 7.2% of the variance in the place of death was associated with municipal-level characteristics. Municipal characteristics were associated with more of the variance than were prefectural characteristics (2.7%). The largest proportional change (7.3%) in variance at the municipality level was observed when enabling factors (ie, medical and long-term care resources) were added to the model. Municipalities with a high proportion of in-home death were more likely to have a higher supply of clinics, physicians, and care workers providing in-home services per population, as well as a lower number of hospital beds and long-term care facility workers per population. In this cross-sectional study, municipal characteristics explained a substantial proportion of the geographic variance in in-home death in Japan. These results suggest that municipal policy makers need to ensure an adequate supply of clinics, physicians, and care workers providing in-home services to meet the preferences of care-dependent older people who wish to spend their final days at home.

본 연구는 불안정한 노동시장에 놓여 있는 시각장애인 안마사들의 안정된 취업처를 모색하기 위해 노인장기요양보험제도에서의 안마서비스 도입을 고찰하는데 그 목적이 있다. 이를 위해 우리나라 보다 고령사회를 먼저 맞이하여 노인요양의 문제를 대처한 일본의 개호보험 사례를 중심으로 문헌분석을 실시하였다. 연구의 내용은 다음과 같다. 먼저 국내 시각장애인 안마업의 현황과 문제를 살펴보고, 다음으로 일본의 개호보험제도에서 제도개요, 급여, 안마사관련 서비스제공인력 등을 중심으로 분석하였다. 이를 통해서 노인장기요양보험제도에서의 안마서비스 도입을 위한 정책적 방향을 제시하고자 하였다. 연구결과, 일본의 경우 요개호고령자의 증가와 개호가족의 부담을 완화할 목적으로 2000년에 개호보험을 도입하였다. 개호보험 도입이후 요개호고령자가 급속히 증가하였고 특히 이들의 중증화가 되면서 의료비 증가 등으로 재정적 압박을 받게 되었다. 일본정부는 재정부담을 완화하기 위해 여러 차례 개호보험을 개혁을 단행하면서 재활서비스, 예방차원의 급여, 지역밀착형 급여 등을 도입하여 고령자의 중증화 속도를 늦추기 위한 예방노력을 하고 있다. 또한 요개호자의 증가에 따라 요구되는 개호인력 수급문제를 해결하기 위해서 개호사회복지사, 케어매니저, 기능훈련지도원 등에 안마사 등 다양한 보건의료 인력풀제도를 마련하여 개호인력 수급에 대처하고 있다. 2017년에 고령사회로 진입한 우리나라도 고령 사회에서 나타날 요양노인들의 중증화 현상에 맞춰 요양예방체계 구축이 시급한 과제이다. 이를 위해 일본에서 시행하여 있는 안마급여와 관련된 재활서비스, 케어매니저 및 기능훈련서비스 도입을 적극적으로 고민해야한다. 이러한 제도를 도입함에 있어 사회적 연대차원에서 시각장애인 안마사 등 사회적 취약계층을 위한 일자리 창출과 사회적 안전망구축에 대한 지혜도 함께 발휘해야 할 것이다.

The association between psychological distress and risk of incident functional disability in elderly survivors after the Great East Japan Earthquake: The mediating effect of lifestyle and bodily pain

Background: We previously reported that psychological distress was associated with an increased risk of functional disability. However, the mechanism of the association remains unclear. Our aim was to estimate the mediating effect of lifestyle and bodily pain on the association among elderly survivors after the Great East Japan Earthquake.Methods: The study population comprised 1037 residents aged ≥ 65 years. The baseline surveys (exposure and mediators) were conducted in 2011. We classified participants into three categories according to their Kessler 6 score (low: 0–9, moderate: 10–12, and high: 13–24) and defined functional disability as certification for long-term care insurance in Japan. The Cox proportional hazards model was used to calculate the hazard ratios (HRs) and 95% confidence intervals (CIs) for incident functional disability according to Kessler 6 categories and explored the mediating effects of lifestyle and bodily pain on the association.Results: During approximately 8 years of follow-up, we documented 271 incident cases of functional disability. Compared with those in the low distress group, the multivariate adjusted HR for incident functional disability was 1.95 (95% CI 1.21–3.13) for those in the high distress group. Time spent walking, going out, and bodily pain significantly mediated the association between psychological distress and incident functional disability by 10.2%, 10.5%, and 10.3% for the high distress group, respectively.Limitations: We did not consider unmeasured confounders and use of appropriate medication.Conclusions: The evaluation and treatment of bodily pain as well as promotion of active lifestyle would be important for preventing disability among disaster survivors.

Management of frailty under COVID-19 pandemic in Japan.

Frailty prevention is a cornerstone for the extension of healthy life expectancy. It is a multi-dimensional construct that includes physical, mental, and social aspects. Frailty is reversible and can be attenuated by intervention; therefore, its early detection is important in primary and community care. The mainstream of disability prevention in Japan, which comprises the Japanese and local governments as well as healthcare workers, was a high-risk approach until 2014. Given the revision on Japan's long-term care insurance law, current ageing health policies have shifted to more population centric approach. Implements group activities called "Kayoi-no-ba" has been valued in Japan as disability prevention initiative. The Kihon Checklist - a 25-item questionnaire - has been broadly used by health experts and researchers to assess frailty in Japan. However, a new 15-item questionnaire has been newly developed to identify frailty and other health-related problems in older people of 75 years and above. This will enable providing the necessary support to frail individuals at any healthcare facility in local communities. The increase in frailty prevalence in older people has been concern during the COVID-19 pandemic. Home-based physical exercise programs are expected to be effective for frailty prevention. Utilization of information and communication technologies, social network services, and video calls has attracted attention for being effective tools to facilitate communication for older people during the pandemic. Further, life course approaches are needed to clarify the midlife risk of frailty development in later life.

Validating care-needs level against self-reported measures of functioning, disability and sarcopenia among Japanese patients receiving home medical care: The Zaitaku Evaluative Initiatives and Outcome Study.

This study aimed to examine the validity of the care-needs levels classified in Japan's long-term care insurance system (LTCI-CNLs) when compared with patients' self-perceived functioning, disability and physical performance among patients receiving home medical care. This was a multicenter cross-sectional study in Japan. Patients who were receiving continuous home medical care and who could respond to the questionnaire were enrolled in this study. In addition to the LTCI-CNLs, the 12-item version of the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) and the SARC-F were used to measure functioning, disability and physical performance (sarcopenia). In addition, correlations and associations of the LTCI-CNLs with the WHODAS 2.0 and SARC-F were analyzed using Spearman correlations and linear mixed models. Data from 181 patients were included in the analyses. The LTCI-CNLs varied, ranging from support level 1 (5.5%) to care-needs level 5 (10.5%), with care-needs level 2 being the most prevalent (24.9%). Moderate correlations of the LTCI-CNLs with the WHODAS 2.0 and SARC-F were found (ρ = 0.58 and 0.44, respectively). Although WHODAS 2.0 and SARC-F scores varied within each LTCI-CNL, predicted WHODAS 2.0 and SARC-F scores increased as LTCI-CNL increased. Dementia was not associated with WHODAS 2.0 or SARC-F. The LTCI-CNLs was associated with self-reported functioning, disability and physical performance among home medical care patients. Future studies can use the LTCI-CNLs as an outcome variable for specific care approaches or as a proxy covariate for casemix status. Geriatr Gerontol Int 2021; 21: 229-237.

Changes in Kihon Checklist items and new Certification of long-term care needs among Japanese community-dwelling elders.

Objective: Physical frailty has been considered a risk factor for certification of long-term care needs (hereafter referred to as Certification) under Japan’s long-term care insurance (LTCI). Therefore, assessment of frailty in elders should be studied from multiple perspectives. The Kihon Checklist (KCL) is widely used to identify need for support/care among Japanese older adults. This study aims to examine the relationship between changes in KCL items and Certification among Japan’s young-old and old-old.Material and Methods: The KCL responses of 7,092 participants were assessed in April 2012 and March 2016, along with gender, age, and living environment. Deaths, Certifications, and relocations were tracked until March 2018. Changes in KCL items were categorized as bad, worse, improved, or good.Results: Between March 2016 and March 2018, about 7.3% of respondents obtained Certifications. KCL item changes increased the risk of new Certification for bad and worse groups, while improved cognitive function among the old-old possibly reduced the risk of new Certification.Conclusion: Therefore, rather than administering the KCL once, identifying KCL changes among people at risk could help prevent or delay their need for long-term care.
