BACKGROUND: Frailty has become a key concern in an aging population. A comprehensive geriatric assessment (CGA) service framework was developed and evaluated aiming to target and connect frail older adults who are at high risk of requiring long-term care services. METHODS: A community-based pilot study was conducted in fiscal year 2016 and 2017 in Kure city, Hiroshima, Japan. Participants aged 65 and over living in Kure city, and 393 persons were extracted from the Kihon Check List (KCL) responses. Among the eligible individuals, 101 consented to participate and received CGA and referred to services based on individual health needs. The efficacy was evaluated by referral rate of services, continuity of the service usage, evaluation of participant's health condition and the quality of life (QoL) after the 6-month follow-up. RESULTS: Ninety-nine (98.0%) participants needed support for the instrumental activity of daily living, 97 (96.0%) were categorized as locomotive syndrome, and 64 (63.4%) had a depressive tendency. Afterward, 60 participants (59.4%) subsequently accepted the referral services, however, 34 (33.7%) used the services and the remaining 26 (25.7%) did not use the services. The health condition improvements in the service-uses group were statistically significant (p < 0.001), however, QoL score did not change between the baseline and 6th -month. CONCLUSION: KCL extracted high-risks older people, and CGA revealed related diseases and health conditions. However, the high refusal rate of referral services indicates a necessity to modify the service framework such as by collaborating with community general support centers, which could increase the efficacy of service framework.

Language：English Publishing type：Research paper (scientific journal)

Older people's health condition is not uniform, and the components of their health are interrelated. Concepts regarding the health of older people have emerged and changed over time. However, the transition of concepts and influencing factors are not well examined through research. We have conducted a scoping review of the changes over time in the concept of health for older people and the factors influencing these changes. The public websites of international organizations and academic societies related to older people's health and research paper database were searched, and the extracted data were summarized in a chronological table. Consequently, this study revealed changing trends in health orientation after health had been defined by WHO, namely, successful aging, productive aging, active aging, and healthy aging, and their components, not the concept of health. The emergence and changes of health orientation among older people may have accompanied proposals and measures of international organizations and academic societies developed in response to changes in the demographic structure, and changes in how society perceives and supports older people. With the changing eras that bring about advances in health technology, prolongation of life expectancy, and changes in lifestyles, the needs of older people, society's perceptions of aging and older people, and how to support them will also change. Our findings may provide a valuable basis for understanding aging and older people, reconsidering their health orientation based on the health issues of older people and their significance, and formulating policies for older people in the future.

Spatially heterogeneous associations between the built environment and objective health outcomes in Japanese cities. Reviewed International journal

Shuangjin Li, Junyi Zhang, Michiko Moriyama, Kana Kazawa

International journal of environmental health research 33 ( 12 ) 1205 - 1217 2023.12

Language：English Publishing type：Research paper (scientific journal)

The built environment is a structural determinant of health. Here we reveal spatially heterogeneous associations of built environment indicators with objective health outcomes (morbidity) by combining a random forest (RF) approach and a multiscale geographically weighted (MGWR) regression method. Using data from six Japanese cities, we found that the ratio of morbidity has obvious spatial agglomerations. The mixed land-use diversity with 1000 m buffer, distance to hospital, proportion of park area with 300 m buffer, and house price with 2000 m buffer, negatively affect health outcomes at all locations. For most locations, high PM2.5 or high floor area ratio with 2000 m buffer are linked to a high ratio of morbidity. Our findings support the use of such data for long-term urban and health planning. We expect our study to be a starting point for further research on spatially heterogeneous associations of the built environment with comprehensive health outcomes.

BACKGROUND: This study aimed to develop a self-assessment scale for care management of people with dementia and examine its reliability and validity. METHODS: Based on Bloom's Taxonomy, previous research, and experts' opinions on dementia and care management, a scale consisting of 18 items was developed to assess care managers' attitudes, knowledge, and skills in their management of people with dementia. To examine the scale's reliability and validity, data were collected from 638 care managers. Construct validity using exploratory factor analysis, known-group validity, and internal consistency reliability of the scale were evaluated. RESULTS: Exploratory factor analysis supported the construct validity with a four-factor model and explained 59.1% of the total variance. Following were the four factors: Factor I 'Person centred care'; Factor II 'Understanding of disease characteristics, treatment and care'; Factor III 'Understanding of people with dementia and care management according to their characteristics'; and Factor IV 'Utilization of local resources surrounding people with dementia'. Regarding the known-group validity, results showed that the group with a qualified chief care manager scored significantly higher than the group without one on Factors I (P = 0.013) and III (P = 0.026). Cronbach's alpha coefficient for the 18 items was 0.928. CONCLUSIONS: The findings prove that the scale has acceptable reliability and validity, and can help care managers reflect on their practice. Future research is desirable to measure the validation of change in the scale.

Aim This study developed a risk scoring tool and examined its applicability using data from the Kihon Checklist cohort dataset for 19 months to predict the transition from no certification for long-term care to long-term care level 3 or above. Methods Data were collected from 26 357 functionally independent, community-dwelling older adults in a Japanese city who answered the Checklist in 2014 and were followed for 19 months. Individuals certified for long-term care during the follow-up period were classified into three levels depending on their certification status: low, moderate, and high long-term care levels. Relationships between the Kihon Checklist domains and high long-term care levels were examined using the logistic regression model. A score chart predicting incidents of high long-term care levels was created to facilitate its applicability. Results As of 2016, 971 participants were certified for long-term care (3.7%), of which 168 (0.6%), 357 (1.4%), and 446 (1.7%) were certified as high, moderate, and low long-term care levels, respectively. Variables associated with the certification of high long-term care level included difficulties in activities of daily living, a decline in locomotor and cognitive function in the Kihon Checklist domains, and age. The score chart was created based on these variables and demonstrated excellent discriminatory ability, with an area under curve of 0.817 (95% confidence interval: 0.785-0.849). Conclusions The Kihon Checklist can predict the future development of a high degree of dependency. The score chart we developed can be easily implemented to identify older adults at high risk with reasonable accuracy.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 19 ( 17 ) 2022.9

Language：English Publishing type：Research paper (scientific journal) Publisher：MDPI

Background: Improving the labor productivity of small and medium-sized enterprises (SMEs) is essential because of the aging population and predicted reduction in the labor force. Therefore, it is necessary to ensure that employees are in good health to work for long times. In this regard, the purpose of the study is to investigate the relationship between work engagement (WE) and related variables among SME employees. Methods: A cross-sectional study was conducted using the baseline data of the prospective cohort study, which included 377 employees from three SMEs headquartered in Hiroshima Prefecture, Japan. Results: A multiple regression analysis was performed to see the associations between Utrecht Work Engagement Scale (UWES) scores and other variables. Significant associations were found with job satisfaction, age, health literacy (HL), and quality of sleep (all, p < 0.05). Additionally, there was a statistically significant difference observed in WE, quality of sleep, concern for own body, job satisfaction, and family life satisfaction (all, p < 0.001) with respect to high and low HL levels. Conclusions: The results of this study reveal that while implementing health and productivity management in SMEs to increase WE, it is best to concentrate on raising HL, job satisfaction, and sleep quality. To increase generalizability, further research could be conducted with more SMEs companies.

Background A prolonged COVID-19 pandemic could exacerbate the risk of infection and undesirable effects associated with infection control measures of older people with dementia (PWD), and the care burden of families. In this study, we examined the efficacy of care manager-led information provision and practical support for families of older PWD who need care, regarding appropriate infection prevention, prevention of deterioration of cognitive and physical functions, and preparedness in cases of infection spread or infection during the pandemic. Methods Fifty-three family members (aged >= 20 years) who were primary caregivers living with older PWD using public long-term care services were enrolled in an one-month randomized controlled trial. This duration was set based on behavior modification theory and with consideration of ethical issue that the most vulnerable people not benefiting from the intervention. The intervention group (IG) received care manager-led information provision and practical support, and the control group (CG) received usual care. Care burden (primary outcome) was measured using the Zarit Caregiver Burden Interview, and secondary outcomes were analyzed using Patient Health Questionnaire-9 (PHQ9), the Fear of COVID-19 Scale, and salivary alpha-amylase activity. Data were collected at baseline and after 1 month. Multiple regression analysis was conducted to examine the efficacy of the intervention. The participants evaluated the care managers' support. Results The participants were randomly divided into IG (n = 27) and CG (n = 26) groups. After the intervention, compared with the CG, there was a decrease in PHQ-9 (beta = -.202, p = 0.044) and alpha-amylase activity in saliva (beta = -.265, p = 0.050) in IG. IG also showed an increased fear of COVID-19 after the intervention (beta = .261, p = 0.003). With the care managers' support, 57.2% of the participants felt secure in their daily lives and 53.1% agreed that they were able to practice infection prevention suitable for older PWD. Conclusions Our findings suggest that the care manager-led intervention may be useful for families of older PWD to enhance behavioral changes in preventing COVID-19 infection and improve their psychological outcomes in the COVID-19 era.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 19 ( 13 ) 2022.7

Authorship：Lead author,　Corresponding author Language：English Publishing type：Research paper (scientific journal) Publisher：MDPI

This longitudinal study aimed to evaluate a community-based and nurse-led advanced case management model centered on disease management. Participants were chronically ill patients aged 20 years and older who were highly dependent on medical care. The case management group (CMG) received nurse-led advanced case management, and the comparison group (CG) was selected by matching estimated propensity scores with the CMG. We compared the changes in medico-economic indicators between the two groups and analyzed the physical and psychological indicators of the CMG over time. The CMG comprised 51 participants, of which eight dropped out by 12 months after registration. After 1:1 propensity score matching, there were 40 participants in the CMG and CG, respectively. At 12 months after the registration, there was no significant difference between the two groups and no change in the CMG. At 24 months after the registration, the CMG's medical and long-term care costs decreased significantly, while the CG's costs increased. Moreover, there was a significant reduction in the number of hospital days and hospital admissions in the CMG. Our findings revealed that nurse-led advanced case management could be useful for patients with complex needs to avoid hospitalization due to exacerbations.
