Clinical subtypes of older adults starting long-term care in Japan and their association with prognoses: a data-driven cluster analysis

We aimed to identify the clinical subtypes in individuals starting long-term care in Japan and examined their association with prognoses. Using linked medical insurance claims data and survey data for care-need certification in a large city, we identified participants who started long-term care. Grouping them based on 22 diseases recorded in the past 6 months using fuzzy c-means clustering, we examined the longitudinal association between clusters and death or care-need level deterioration within 2 years. We analyzed 4,648 participants (median age 83 [interquartile range 78–88] years, female 60.4%) between October 2014 and March 2019 and categorized them into (i) musculoskeletal and sensory, (ii) cardiac, (iii) neurological, (iv) respiratory and cancer, (v) insulin-dependent diabetes, and (vi) unspecified subtypes. The results of clustering were replicated in another city. Compared with the musculoskeletal and sensory subtype, the adjusted hazard ratio (95% confidence interval) for death was 1.22 (1.05–1.42), 1.81 (1.54–2.13), and 1.21 (1.00–1.46) for the cardiac, respiratory and cancer, and insulin-dependent diabetes subtypes, respectively. The care-need levels more likely worsened in the cardiac, respiratory and cancer, and unspecified subtypes than in the musculoskeletal and sensory subtype. In conclusion, distinct clinical subtypes exist among individuals initiating long-term care.

Factors influencing interprofessional collaboration in long-term care from a multidisciplinary perspective: a case study approach

ABSTRACT Systematic assessments of interprofessional collaboration barriers and enablers in long-term care settings are critical for delivering person-centered healthcare. However, research on factors influencing interprofessional collaboration in long-term care settings is limited. For this study, 65 healthcare professionals across multiple facilities experienced in long-term care in Japan participated in online focus group discussions and individual interviews to discuss cases. The qualitative data were analyzed using qualitative content analysis. Seven themes emerged: coordination, the need for care manager training, hierarchy among healthcare professionals, specialization but not the mind-set of overspecialization, casual conversations, electronic group communication tools, and excessive fear of personal information protection. These findings highlight the need to develop coordinator roles and for interprofessional education on the proper approach to personal information protection laws. Furthermore, daily casual conversations, the use of online platforms, and the prevention of patients being left behind due to overspecialization are required.

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.

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.

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.

U-shaped link of health checkup data and need for care using a time-dependent cox regression model with a restricted cubic spline

We explored risk indicators likely to result in older adults needing certified long-term care in Japan and ascertained whether this relationship forms a U-shaped link. We analyzed a community-based cohort of residents in Kitanagoya City, Aichi Prefecture, Japan. Participants were 3718 individuals aged 65 years and above who underwent health examinations between April 1, 2011 and March 31, 2012. For continuous clinical variables, we applied a time-dependent Cox regression model. Two types of models were applied—a linear and nonlinear model with restricted cubic splines—to assess the U-shaped association. Statistical significance (set at 0.05) for the nonlinearity was tested by comparing the spline and linear models. Among the participants, 701 were certified as needing Level 1 care or higher during a follow-up. Among the continuous clinical variables, the nonlinear model for body mass index, systolic blood pressure, high-density lipoprotein cholesterol, alanine aminotransferase, aspartate aminotransferase, and γ-glutamyl transpeptidase revealed significant U-shaped associations as compared with the linear model in which the outcome was a certification of the need for nursing care. These results provide an important insight into the usefulness of nonlinear models for predicting the risk of such certification.

Toward developing care outcome quality indicators for home care for older people: A prospective cohort study in Japan.

Care quality in Japan's long-term care (LTC) agencies, including home care, is the responsibility primarily of individual agencies, and the evaluation of service processes and outcomes is minimal. To describe the development of quality indicators for LTC (QIs-LTC) in Japan. QIs-LTC were developed through literature review and expert panel discussions and then were piloted and used in a 2-year longitudinal survey. The survey (launched in September 2019) targeted older people receiving home care (n = 1450), their family members (n = 880), their professional home care providers (n = 577), and managers of home care agencies (n = 122). Across eight domains (maintaining dignity, minimizing symptoms and disease deterioration, maintaining nutritional status, maintaining bladder/bowel control, encouraging physical activities, experiencing sound sleep, maintaining serenity and contentedness, and maintaining family's well-being), 24 care quality objectives were set with 24 outcome QIs-LTC and 144 process QIs-LTC. In the survey, 84.8% of clients were using home care nursing, 26.3% were living alone, and 39.5% had dementia. In the month preceding the data collection, 13.9% of clients had a new disease or worsening of an existing disease, 8.8% were hospitalized at least once, and 47.9% did not participate in activities of interest. About 20% of clients' families were unable to spend time peacefully, and 52.8% were exhausted from the client's care. The QIs-LTC developed in the current study are generic and client- and family-centered. They encompass objective and subjective information and would facilitate standardized monitoring if adopted and comparison between LTC settings, including home care. In addition, future research directives are outlined. Geriatr Gerontol Int 2023; 23: 383-394.

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.

Long-Term Care in Japan

Long-Term Care in Japan

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.

The Experience and Enlightenment of the Community-Based Long-Term Care in Japan.

(1) Background: China’s population aging situation is severe, but the construction of the long-term care insurance system is still in its infancy. Through summarizing the long-term care experience in Japan, this paper explores the suggestions for the development of long-term care in China. (2) Methods: Based on literature research and policy review, we sorted out the relevant practices and safeguard measures of the long-term care insurance system in Japan, and summarized the characteristics of Japanese community care. (3) Results: In the development of long-term care services, Japan has gradually established a multi-level, systematic, and precise elderly care service model. Its community care has the characteristics of policy support, intensive intervention, complete elements, and strict evaluation. China’s long-term care services should learn from Japan’s experience, strengthen institutional guarantees, improve relevant supporting policies, encourage multiple subjects to participate in community care based on integrating community resources, and establish community care evaluation mechanism.

The course of broken dreams: The expectations and realities of the life of Indonesian nurses as care workers in Japan

<h2>ABSTRACT</h2><h3>Background</h3> Despite the contribution of international nurses to the health care services at a destination country, migrant nurses are not always employed based on their competency. Sending nurses to work as care workers in Japan might contradict the international migration of Indonesian health workforce policy which promotes the brain cirulation. Examining the life and work experiences of Indonesian nurses in Japan provides insight into stages of the migratory journey on a receiving country. <h3>Purpose</h3> The aim of this study was to describe the narratives and experiences of Indonesian nurse migrants who worked as care workers in Japanese long-term care facilities. <h3>Methods</h3> A qualitative descriptive method was employed and a purposive sample of 18 Indonesian nurses participated in this study. Semi-structured interviews were conducted among those participants who worked in long-term care facilities across four prefectures in Japan. Data were analysed using content analysis, supported by QSR NVIVO 10 software. <h3>Results</h3> Three key themes emerged from the data analysis: (i) broken dreams; (ii) surviving the struggle; and (iii) supportive environment. These three themes include the unmet expectations of the participants, their experiences as foreign care workers, and the support they received from their work environment. <h3>Conclusion</h3> Indonesian nurses in this study who migrated and worked in Japan's long-term care facilities as care workers were left disillusioned due to unmet expectations but able to cope with the challenges with supports from the institution and people at their workplace. International care workers with nursing educational backgrounds should be provided with opportunities to develop their professional careers.

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.

Robotic devices and ICT in long-term care in Japan: Their potential and limitations from a workplace perspective

ABSTRACT In light of its rapidly aging society, Japan is pressured to full-heartedly address the labor shortage in long-term care. Among the various policy options currently in discussion, government agencies and business sector representatives agree that robotic devices and information and communication technology (ICT) constitute a suitable countermeasure. However, during our research in Japan in 2019, we found that robotic devices and ICT are only reluctantly being introduced into long-term care facilities. Based on our field visits and interviews as well as supplementary document research, this paper discusses the potential that facility managers ascribe to robotic devices and ICT when it comes to alleviating the labor shortage in the long-term care institutions they run. Of particular interest is the question to what degree the usage of robotic devices and ICT could reduce the physical hardships and mental stress that staff in long-term caregiving experience. This paper will further our understanding of the labor situation in long-term care facilities and contribute to the research field of robotic devices and ICT in Japan’s labor market.

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.

Factors Associated with Denture Non-use in Older Adults Requiring Long-Term Care

BackgroundEvidence suggests that denture non-use is significantly associated with activities of daily living, oral function, and cognitive decline. Few studies have focused on the possibility that the indications for denture use may differ depending on the cognitive and physical functions in older adults requiring long-term care. ObjectivesThe aim of this study was to elucidate the factors associated with denture non-use in older adults requiring long-term care. MethodsThis cross-sectional study comprised 201 older adults (45 men and 156 women; average age = 86.2 ± 7.1 years) requiring long-term care in Japan. Those who did not require denture treatment were classified by dentists into denture-use and denture non-use groups. The severity of dementia was assessed using the Clinical Dementia Rating scale. Multiple logistic regression analyses were conducted to detect the factors significantly associated with denture non-use. ResultsThe proportion of participants without dentures was 58.2%. Multiple logistic regression analyses revealed that a moderate dementia (odds ratio [OR], 4.44; 95% confidence interval [CI] 1.18–16.71, p=0.027) and rinsing ability (OR 3.00; 95% CI 1.12–8.06; p=0.030) were significant factors related to the non-use of dentures. ConclusionSeverity of dementia and rinsing ability were significantly associated with non-use of dentures. These findings indicate the necessity of evaluating oral and cognitive functions while planning denture treatment in older adults requiring long-term care.
