Collaborative Care Models of Primary Care Clinics for People with Early-Stage Dementia: A Cross-Sectional Survey of Primary Care Physicians in Japan.

Objectives: This study explored collaboration models between primary care physicians (PCPs) and care managers (CMs) and assessed each model's potential in meeting the support needs of individuals with early-stage dementia. Methods: In 2022, a cross-sectional survey was conducted among the PCPs in Tokyo. The data regarding the participant and clinic characteristics and daily practices for individuals with early-stage dementia were collected. The clinical collaborative practice was classified using a latent class analysis; comparisons were made between the identified classes based on 14 items in seven domains of support. Results: Two collaborative and one stand-alone models were identified. The former varied in the professionals' roles, with one led by PCPs and the other by CMs. We named them PCP-led, CM-led, and stand-alone models, accounting for 46.4%, 32.8%, and 20.6% of the clinics, respectively. The PCP-led clinics were significantly more likely to provide support than the stand-alone ones across five domains: cognitive function, care planning, carers' support, information, and social health. The CM-led model clinics generally fell between those of the other two models. Conclusion: Different leadership styles exist in the PCP-CM collaborations in care delivery for people with early-stage dementia. This collaboration offers distinct advantages for clinics in addressing their needs.

Effects of multimorbidity and polypharmacy on physical function in community-dwelling older adults: A 3-year prospective cohort study from the SONIC.

BACKGROUND: We prospectively examined the effect of baseline multimorbidity and polypharmacy on the physical function of community-dwelling older adults over a three-year period. METHODS: The analysis included 1,401 older adults (51.5 % women) who participated in both wave 1 and wave 2 (3-year follow-up) of the Septuagenarians, Octogenarians, and Nonagenarians Investigation with Centenarians (SONIC) study. Grip strength and walking speed were binarized into poor/not poor physical function according to the frailty definition. The number of chronic conditions and the number of prescribed medications were categorized into 3 and 4 groups, respectively. Multivariable logistic regression was used to examine associations between the number of chronic conditions, medication use at baseline, and poor physical function over a three-year period. RESULTS: After adjusting for confounding factors, hyperpolypharmacy (≥ 10 medications) demonstrated associations with weak grip strength (adjusted odds ratio [aOR] = 2.142, 95 % confidence interval [CI] = 1.100-4.171) and slow walking speed (aOR = 1.878, 95 % CI = 1.013-3.483), while co-medication (1-4 medications) was negatively associated with slow walking speed (aOR = 0.688, 95 % CI = 0.480-0.986). There was no significant association between the number of chronic conditions and physical function. CONCLUSION: The findings suggest that the number of medications can serve as a simple indicator to assess the risk of physical frailty. Given that many older individuals receive multiple medications for extended durations, medical management approaches must consider not only disease-specific treatment outcomes but also prioritize drug therapy while actively avoiding the progression towards frailty and geriatric syndromes.

Effect of number of medications on the risk of falls among community-dwelling older adults: A 3-year follow-up of the SONIC study.

AIM: This study examined the association between the number of prescribed medications and falls among community-dwelling older adults. METHODS: We conducted a geriatric comprehensive health-checkup on community-dwelling adults aged 69-91 years who participated in the Septuagenarians, Octogenarians, and Nonagenarians Investigation with Centenarians study. The final analysis of this study included 1,076 participants with complete data. The participants were divided into four groups based on the number of medications at baseline: 0, 1, 2-4, and ≥5. At the 3-year follow-up, the participants were asked whether they had fallen in the past year. Multivariable logistic regression analysis was performed to assess the relationship between the number of medications taken and falls after adjusting for confounding factors. RESULTS: The prevalence rates of falls were 10.5%, 18.2%, 18.3%, and 19.8% in the no-medication, one-medication, comedication, and polypharmacy groups, respectively. In the one-medication prescription group, 59% of prescriptions were for fall-risk-increasing drugs (FRID). Multivariable analysis showed a significantly higher incidence of falls in the one-medication group (adjusted odds ratio [OR], 1.91; 95% confidence interval [CI], 1.04-3.54), co-medication (OR, 1.89; 95% CI, 1.09-3.29), and polypharmacy groups (OR, 1.94; 95% CI, 1.09-3.45) than in the no-medication group. CONCLUSIONS: The study showed that polypharmacy, as well as just taking one medication, can affect the occurrence of falls. This suggests that in addition to the number of medications and polypharmacy, the type of medication, such as FRID, affects the risk of falls. Therefore, pharmacotherapy should consider the risk of falls in older adults when prescribing medications. Geriatr Gerontol Int 2024; 24: 306-310.

Older people living in the community with delusion.

AIM: This study explores the intricate relationship between social interactions and the development of persecutory delusions among older women living alone in Japan. Focusing on the unique perspective of individuals experiencing delusions outside clinical settings, the aim was to understand the impact of interpersonal interactions on delusion formation. METHODS: Cases of older women living alone with persecutory delusions were selected from records of municipal psychogeriatric services and medical consultations within a community space. This study employed a descriptive approach to propose a hypothesis regarding the possible connection between social interactions and the development of persecutory delusions within this demographic. RESULTS: Two relevant cases were identified, from which a three-step hypothesis emerged regarding the potential link between social interactions and the development of persecutory delusions in this demographic. Insights from these cases suggest that anxiety can trigger hallucinations, which, when unaddressed, evolve into delusional interpretations. Addressing these unmet needs could mitigate the progression of persecutory delusions. CONCLUSIONS: The findings of this study underline the critical relationship between social interactions and persecutory delusions among older women living alone. The unmet need for empathy influences the progression from anxiety-driven hallucinations to fully formed delusions. Early intervention can prevent the escalation of delusions and involuntary psychiatric hospitalization. This study underscores the importance of recognizing the link between social isolation and delusion emergence. It advocates for compassionate environments to meet the psychological needs of older individuals grappling with delusions. Geriatr Gerontol Int 2024; 24: 118-122.

Encouraging death communication in a death-avoidant society: analysis of interviews with death café organizers.

BACKGROUND: Post-war Japanese tend to avoid discussion of death, resulting in a lack of death communication within clinical settings. However, with the aging of society, the significance of conversations and decisions related to end-of-life issues has grown. In 2007, the government established guidelines for decision-making in end-of-life care. Nonetheless, death communication remains a challenge for healthcare professionals in clinical settings. In contrast, death cafés have spontaneously emerged within communities as informal gatherings to openly discuss and explore death. Learning from death café organizers may help healthcare professionals encourage death communication in a death-avoidant society. Therefore, a qualitative study was conducted to describe death cafés by examining the underlying motivation and practices through interviews with death café organizers. METHODS: Individual in-depth interviews were conducted with death café organizers. Two key aspects were explored: 1) the underlying motivations of organizers; and 2) the practices and challenges encountered in running death cafés. The interviews were transcribed verbatim and analyzed using a qualitative descriptive approach. Thematic analysis was used. RESULTS: The study identified two themes representing the underlying motivation of death café organizers: individually-oriented and community-oriented. These themes exhibited contrasting orientations and were collectively termed "individual-community orientation". Regarding the practice of death cafés, the focus was on the "attitude towards having attendees with and without grief in the same session." Participants' attitudes towards this aspect fell into two categories with opposing orientations: "purification" and "inclusion." The "purification-inclusion orientation" was more prevalent among organizers who initiated death cafés due to their personal experiences. A matrix was created to categorize death cafés based on their underlying motivations (individual vs. community-oriented) and practices (purification vs. inclusion). This classification resulted in quadrant 1 (community-oriented, inclusive) and quadrant 3 (individually-oriented, purification). Notably, death cafés in quadrant 1 were often held in temples. CONCLUSIONS: Japanese death cafés can be classified into two categories: individually and purification-oriented and community and inclusive-oriented categories. Healthcare professionals can learn valuable insights from death café organizers, particularly in promoting death communication. Specifically, temple death cafés, with their inclusive practices and orientation towards community, can be particularly beneficial in fostering inclusivity and community engagement.

[Acute Aortic Dissection Complicated by IgA Deficiency].

Immunoglobulin A (IgA) deficiency is the most common type of primary immunodeficiency. When a patient receives a blood product transfusion, anti-IgA antibodies are formed. Second transfusion may sometimes cause an anaphylactic reaction, thus caution is necessary. Reported here is a case of Stanford type A acute aortic dissection performed in the patient with IgA deficiency with a history of blood transfusion. Red blood cells and platelet were washed and prepared, and flesh frozen plasma from IgA deficient donors was obtained. Thereafter, the surgery was safely performed.

[The expected role of Dementia Support Doctors in dealing with complex cases of older people with dementia].

AIM: The present studyinvestigated the roles expected of Dementia Support Doctors (DSDs) in dealing with complex cases. METHODS: The participants were attendees of the education programs organised by the Center for Promoting Dementia Support and the Medical Center for Dementia at the Tokyo Metropolitan Geriatric Hospital from April 2021 to March 2022. A self-administered postal questionnaire survey was conducted. The questionnaire included items on the basic attributes of the participants, their experiences with the issues associated with complex cases, and role expectations of consulting/collaboration partners when dealing with complex cases. RESULTS: The valid response rate was 49.3%. DSDs were expected by primary physicians, Community General Support Center staff and administrative staff to diagnose dementia and give advice on support strategies for complex cases. Primary physicians further expected them to initiate pharmacotherapy with anti-dementia drugs and address the pharmacotherapy needs for managing Behavioral and Psychological Symptoms of Dementia. It was also found that DSDs' experience with complex cases was comparable to that of the staff at the Medical Centers for Dementia. Of note, DSDs were mentioned less frequently as consulting/collaboration partners than Medical Centers for Dementia and primary physicians. CONCLUSIONS: The study showed that DSDs play an important role in dealing with complex cases. The roles of DSDs and ways to collaborate with them need to be communicated through interprofessional education.

Criterion validity of the health assessment questionnaire for the national screening program for older adults in Japan: The SONIC study.

AIM: In our previous study, we proposed that the total score of the 12 frailty-related items in the health assessment questionnaire for the national screening program for older adults could be used as an indicator of frailty. We aim to examine the criterion validity of the 12 frailty-related items for frailty. METHODS: The data used in this study were from older Japanese individuals aged 78-81 years (n = 461) who participated in the in-venue (2019) and mailed questionnaire (2020) surveys of the Septuagenarians, Octogenarians, Nonagenarians Investigation with Centenarians study. A receiver operator characteristic (ROC) curve analysis was used to evaluate the criterion validity of the 12 frailty-related items for frailty defined based on the Japanese version of the Cardiovascular Health Study criteria. A multivariable logistic regression model was used to examine the independent association of the 12 frailty-related items with frailty. RESULTS: The area under the ROC curve of the scores of the 12 frailty-related items for frailty was 0.79 (95% confidence interval [CI] = 0.73-0.85, P < 0.001). The cut-off value for frailty was 3 and 4 points, and the sensitivity and specificity were 55.9% and 85.8%, respectively. The multivariable logistic regression model showed that four or more scores of the 12 frailty-related items were significantly associated with frailty (adjusted odds ratio = 7.75, 95% CI = 4.10-14.65, P < 0.001). CONCLUSIONS: The results of this study suggest that the 12 frailty-related items in the health assessment questionnaire for older adults may be useful for assessing frailty in community-dwelling older adults in a simplified manner.

Characteristics of people seeking consultation after progressing to severe dementia: A mixed-method analysis.

OBJECTIVES: This explores the characteristics of patients with worsening dementia who did not receive a specialized medical examination or care. METHODS: This study utilized a mixed methods analysis. Of the 2712 people who received the Mini Mental State of Examination (MMSE) at the Community Consultation Center for Citizens with MCI and Dementia between December 2007 and December 2019, 1413 people who scored 23 points or less were included. Participants were categorized into mild, moderate, and severe groups, based on their MMSE scores. Participants' characteristics-gender, age, presence or absence of an escort, demographics, family type, and presence or absence of a family doctor-were compared between the groups. To further understand the severe group's characteristics, clinical psychologists recorded consultation forms were categorized. RESULTS: More than 80% of the patients in each group had a family doctor. Moreover, all the severe groups had escorts, and the role of family members and supporters was important for the consultation. In the severe group, 29 patients had never received specialized medical care. Their characteristics were coded "non-existence" (fewer people or opportunities to notice their needs), "connection failure" (a lack of access or connections to consultations), and "evaluation failure" (not recognized as a problem requiring consultation). CONCLUSIONS: It is necessary to improve primary physician education, disseminate knowledge, and raise awareness about dementia, besides building and strengthening networks to alleviate the isolation of dementia patients and their families. The psychological aspects of family members' denial regarding their family members with dementia must be addressed through intervention.

Middle-aged and older people with urgent, unaware, and unmet mental health care needs: Practitioners' viewpoints from outside the formal mental health care system.

BACKGROUND: Mental health challenges are highly significant among older individuals. However, the non-utilization of mental health services increases with age. Although universal health coverage (UHC) was reported to reduce unmet health care needs, it might not be sufficient to reduce unmet mental health care needs from a clinical perspective. Despite the existence of UHC in Japan, this study aimed to explore the factors related to the non-utilization of formal mental health care systems among middle-aged and older people with urgent, unaware, and unmet mental health care needs. METHODS: Purposeful sampling was used as the sampling method in this study by combining snowball sampling and a specific criterion. The interviewees were nine practitioners from four sectors outside the mental health care system, including long-term care, the public and private sector, as well as general hospitals in one area of Tokyo, where we had conducted community-based participatory research for five years. The interviews were conducted by an interdisciplinary team, which comprised a psychiatrist, a public health nurse from a non-profit organization, and a Buddhist priest as well as a social researcher to cover the broader unmet health care needs, such as physical, psychosocial, and spiritual needs. The basic characteristics of the interviewees were enquired, followed by whether the interviewees had case of middle-aged or older individuals with urgent, unaware, and unmet mental health care needs. If the answer was yes, we asked the interviewees to describe the details. The interviews pertinent to this study were conducted between October 2021 and November 2021. In this study, we adopted a qualitative descriptive approach. First, we created a summary of each case. Next, we explored the factors related to the non-utilization of formal mental health care systems by conducting a thematic analysis to identify the themes in the data collected. RESULTS: The over-arching category involving "the factors related to an individual person" included two categories, as follows: 1) "Individual intrinsic factors," which comprised two sub-categories, including "difficulty in seeking help" and "delusional disorders," and 2) "family factors," which comprised "discord between family members," "denial of service engagement," "multiple cases in one family," and "families' difficulty in seeking help." The over-arching category "the factors related to the systems" included four categories, as follows: 1) "Physical health system-related factors," which comprised "the indifference of physical healthcare providers regarding mental health" and "the discontinuation of physical health conditions," 2) "mental health system-related factors," which comprised "irresponsive mental health care systems" and "uncomfortable experiences in previous visits to clinics," and 3) "social service system-related factors," which comprised "the lack of time to provide care," "social service not allowed without diagnosis," and "no appropriate service in the community," as well as 4) " the lack of integration between the systems." Apart from the aforementioned factors, "the community people-related factor" and "factors related to inter-regional movements" also emerged in this study. CONCLUSIONS: The results of this study suggest a specific intervention target, and they provide further directions for research and policy implementation. The suggested solutions to the issues pertinent to this study are as follows: the recognition of the ways in which older people may inadequately understand their health or be unaware of available services, the building of a therapeutic alliance for "the individual intrinsic factors." Regarding the "family factors," the solutions include the provision of particularly intensive care for families with family discords, families with multiple cases, and families who find it difficult to seek help, as well as making intensive efforts for ensuring early involvement after contact with health care services. Regarding the "the factors related to the systems," the solutions include the implementation of mental health education campaigns aimed at enhancing mental health knowledge among non-mental health professionals, as well as formulating and implementing reforms ensuring that such professionals are increasingly responsible especially with regard to emergency inpatient care. It also include listening without ageism in clinical practice, the expansion of social services regarding human resources and the flexibility of use which increases the breadth of the types of care, as well as facilitating the integration between the associated health care systems. Further suggestions include encouraging community residents to join social security systems as well as the provision of particularly intensive care for people who have just moved in.

Characteristics of complex cases of community-dwelling older people with cognitive impairment: A classification and its relationships to clinical stages of dementia.

AIM: Older people with severe and complex needs are a major challenge in the realm of community health. However, despite the importance of the issue there is a lack of knowledge regarding complex cases of community-dwelling older people with cognitive impairment (hereafter referred to as "complex cases"). The first aim of this study was to develop a framework for the comprehensive assessment and analysis of the issues faced by complex cases. The second aim was to identify the relationships between these issues and the clinical stages of dementia using the Clinical Dementia Rating (CDR). METHODS: A consecutive case series study was conducted using the records of 293 cases in municipal psychogeriatric services. Descriptions regarding the issues faced by complex cases were extracted from the case records and categorized. Next, trends according to CDR were analyzed. The association between each category and the CDR was then examined by multivariate analysis. RESULTS: The issues faced by complex cases were categorized into five categories: A, Mental Health Issues; B, Physical Health Issues; C, Family Issues; D, Issues of Neighborhood Communication; and E, Financial Issue. The higher the CDR score, the higher the frequency of categories C and E, the lower the frequency of category A, and the more categories each case faced. After adjusting for possible confounders, CDRs were associated with the categories of issues faced by complex cases. CONCLUSIONS: The analytical framework developed in the present study will help in the categorization of the complexity of complex cases and the development of intervention strategies. In addition, by incorporating the perspective of the clinical stage of dementia, more effective support can be provided. Geriatr Gerontol Int 2022; 22: 997-1004.

Construct Validity of a New Health Assessment Questionnaire for the National Screening Program of Older Adults in Japan: The SONIC Study.

The Japanese government has implemented a new screening program to promote measures to avoid worsening lifestyle-related diseases and frailty among the older population. In this effort, the government formulated a new health assessment questionnaire for the screening program of old-old adults aged ≥75 years. The questionnaire comprises 15 items, of which 12 address frailty, two address general health status, and one addresses smoking habits. This study examined the construct validity of this questionnaire, using the explanatory factor analysis (EFA) and confirmatory factor analysis (CFA). The data used in this study were drawn from a mail-in survey conducted in 2020 as part of the Septuagenarians, Octogenarians, Nonagenarians Investigation with Centenarians study. A total of 1576 respondents (range, 78-99 years of age) were included in the study. Although the EFA did not show an interpretable factor structure of the questionnaire with 15 items, the CFA using only 12 frailty-related items showed the goodness of fit for a higher-order factor "frailty", and the five frailty-related sub-factors model was acceptable. These results suggest that the total score of the 12 frailty-related items in the questionnaire can be used as an indicator of the degree of "frailty".

[Comprehensive health assessment of community-dwelling older people using mail method and its association with future transition to need for long-term care and dementia].

Objectives　We selected assessment items that can be used to evaluate the physical, mental, and social functions of community-dwelling older people comprehensively and easily, and examined whether these items could predict a future transition to the requirement for nursing care and dementia.Methods　We conducted a self-administered mail survey of 4,439 community-dwelling older people, who were not certified as requiring nursing care in 2011. The items for the survey were shortlisted out of a total of 54 items that were selected by referring to existing scales, and the evaluation items were determined by pass rate and factor analysis. The cut-off point of the total scores was estimated by ROC analysis using the certification of requiring long-term care (support level 1 or higher) and level of independence in the daily lives of older people with dementia (independence level I or higher) in 2014 as external criteria. The predictive validity was examined by binomial logistic regression analysis using the cut-off point of the total score and the score of the sub-domains as explanatory variables, and the requirement of nursing care and independence level of dementia in 2014 as objective variables.Results　A factor analysis of 1,810 subjects with no deficiencies in the 54 items identified 24 items in five domains (mental health, walking function, Instrumental Activities of Daily Living (IADL), cognitive function, and social support). During the ROC analysis, the cut-off point of the total score was estimated to be 20/21 points (nursing care: AUC 0.75, sensitivity 0.77, specificity, 0.56; dementia: AUC 0.75; sensitivity 0.79, specificity 0.55). The binomial logistic regression analysis showed that persons with a total score of less than 20 points in 2011 were significantly more likely to be certified as requiring nursing care (odds ratio 2.57, 95%CI 1.69-3.92, P<0.01) or show a decline in their independence level of dementia (odds ratio 3.12, 95%CI 1.83-5.32, P<0.01) in 2014. The scores of mental health, walking function, and IADL were significantly associated with certification of requiring nursing care, while walking function and cognitive function were significantly associated with dementia.Conclusion　We believe that the selected items in this study can successfully predict a transition to needing nursing care and dementia in the future. In the sub-domains, the results suggested an association with physical and mental function, as has been previously reported, but little association with social function.

[Lipomatous Hypertrophy of Interatrial Septum in Patient with Venous Thrombus:Report of a Case].

A 64-year-old female underwent a computed tomography (CT) examination of the chest because of pneumonia, which revealed lipomatous hypertrophy of the atrial septum. During medical treatment for pneumonia, venous thrombus of the superior vena cava occurred and then disappeared following apixaban administration. The patient refused surgery at that time, thus follow-up examinations include CT scans were conducted at the outpatient clinic. Two years later, the tumor became larger, and this time she accepted surgery. Under total cardiopulmonary bypass with beating heart a 5.0×3.5 cm tumor was resected. Because of its location very close to superior vena cava, upper area of the right atrium was augmented using a bovine pericardium. Following surgery, sick sinus syndrome developed and pacemaker implantation was performed. Thereafter, the patient had a smooth recovery and no recurrence is noted one year since.

Factors associated with inability to attend a follow-up assessment, mortality, and institutionalization among community-dwelling older people with cognitive impairment during a 5-year period: evidence from community-based participatory research.

BACKGROUND: The aim of the present study was to explore factors associated with (i) the inability to attend a follow-up assessment in the community-based participatory research (CBPR) framework; (ii) mortality; and (iii) institutionalization, across a 5-year period among older people with cognitive impairment identified via an epidemiological survey. METHODS: The participants were 198 older people whose score on the Mini-Mental State Examination was below 24, and who were living in our CBPR region in the Tokyo metropolitan area. Baseline data included sociodemographic factors, health-related factors, social factors, and assessments by healthcare professionals. Over the following 5 years we observed what happened to the subjects within the CBPR framework. Bivariate and stepwise multiple logistic regression analyses were performed to explore the factors associated with the inability to attend a follow-up assessment, 5-year mortality, and institutionalization. RESULTS: Participants who did not attend a follow-up assessment tended to live alone. Being older (>80), living with others, frailty, and the need for rights protection and daily living support were associated with increased mortality. Long-term care insurance certification was strongly associated with institutionalization as a natural consequence of the health-care system. Having dementia and low access to doctors were also positively associated with institutionalization. CONCLUSIONS: Older people with cognitive impairment who are living alone are at higher risk of being overlooked by society. To move toward more inclusive communities, the following are recommended: (i) more interventions focusing on older people living alone; (ii) social interventions to detect daily life collapse or rights violations; and (iii) more support to help people with dementia continue living in the community.

Diogenes syndrome in a 10-year retrospective observational study: An elderly case series in Tokyo.

OBJECTIVES: Supporting people suffering from Diogenes Syndrome (DS) is a challenge for geriatric psychiatry. However, there is a lack of knowledge about DS in Japan. Therefore, a systematic longitudinal study to clarify the factors associated with DS and its prognosis was conducted. METHODS/DESIGN: A retrospective study using data from case records of a municipal psychogeriatric service was conducted. The study population was socially isolated older adults with complex mental health and social care needs who had been referred to the service over 10 years. The participants were stratified into DS and non-DS groups, multivariate analysis was performed to identify factors associated with DS, and survival analysis was performed. RESULTS: Of the 270 participants, 61 with Environmental Cleanliness and Clutter Scale (ECCS) scores >12 were assigned to the DS group, and 209 with ECCS scores ≤12 were assigned to the non-DS group. On multiple logistic regression analysis, significantly more people in the DS group were living alone, had advanced dementia, and had reduced basic activities of daily living (BADL) compared to the non-DS group. Furthermore, survival analysis showed that the DS group had a higher risk of early death than the non-DS group. CONCLUSIONS: In the present study, social isolation, living alone, advanced dementia, and reduced BADL were found to be associated with DS. In addition, DS had a high risk of early death. Support for DS must take into account not only mental and social health, but also physical health from an early stage.
