A preliminary study on the development of care staff's Final-Stage Decision-Making Support Scale for older adults with dementia.

AIM: This preliminary study aimed to develop a care staff Final Life-Stage Decision-Making Support Scale (FS-DM) for older adults with dementia (OwDs) in geriatric facilities. METHODS: The FS-DM items were developed from focus group interviews with care staff and reviewed through discussions with several experts in dementia care. A questionnaire survey was conducted among care staff in geriatric facilities from February to March 2021. RESULTS: In total, 138 carers (110 [79.7%] women and 28 [20.3%] men, mean age: 41.5 ± 2.3 years) participated. Among them, 91 (65.9%) were professional caregivers, and 36 (26.1%) were nurses. The FS-DM was developed using a factor analysis, which resulted in 11 items grouped into three factors', as it is the three factors: (1) support for the realization of the wills of OwDs in their final life-stages through collaboration with families and multiple professionals; (2) consideration of communication regarding the formation and expression of the wills of OwDs in their final life-stages; and (3) support for eliciting the wills of OwDs during their final life-stages according to their decision-making ability and values. The factor loadings ranged from 0.385 to 0.827, and the accumulated contribution ratio was 61.03%. The reliability analysis yielded a Cronbach's α of 0.740-0.855. The first and second factors of the FS-DM were significantly correlated with the Approaches to Dementia Questionnaire item "Nurses' attitudes towards support for decision-making." CONCLUSION: Our results suggest that the FS-DM could provide supportive care for OwDs to formulate, express, and realize their will, and that it has a degree of reliability and validity.

Prevalence of dysphagia in patients after orthopedic surgery.

OBJECTIVES: Oropharyngeal dysphagia is one of the most prevalent health complications in older adults. The prevalence of postoperative dysphagia is expected to rise with the increasing number of older patients undergoing orthopedic surgery; however, the specific prevalence and contributing factors remain unclear. This scoping review aimed to identify the prevalence and factors related to postoperative dysphagia in older orthopedic patients. METHODS: This review included studies published up to September 2022 on postoperative patients aged ≥ 60 years who underwent orthopedic surgery. We searched MEDLINE, EMBASE, CINAHL, CENTRAL, Web of Science, and Ichushi-Web. RESULTS: In total, 21 of the 2158 identified studies were reviewed. The studies were classified into the three categories according to the surgical site: cervical spine disease (n = 12), hip fracture (n = 7), and others (n = 2). The estimated dysphagia prevalence rates [95 % confidence interval] of cervical spine disease, hip fractures, and others were 16 % [8-27], 32 % [15-54], and 6 % [4-8], respectively. Factors related to postoperative dysphagia included cervical alignment in cervical spine disease, being older within the cohort, preoperative health status, malnutrition, and sarcopenia in hip fractures. CONCLUSIONS: The prevalence of postoperative dysphagia after orthopedic surgery was highest for hip fractures, followed by cervical spine and others. These results suggest non-neurogenic dysphagia in older patients undergoing orthopedic surgery and indicate that sarcopenia may contribute to postoperative dysphagia in this population. Therefore, further research should clarify the trajectory of postoperative dysphagia and the effectiveness of rehabilitation for postoperative dysphagia after orthopedic surgery.

Effect of Exercise Therapy on Incident Admission in Patients with Type 2 Diabetes Mellitus Undergoing Inpatient Diabetes Self-management Education and Support Tokyo Metropolitan Toshima Hospital, Tokyo Metropolitan Hospital Organization, Japan.

BACKGROUND: Exercise therapy is the key to preventing admission of patients with type 2 diabetes mellitus (T2DM). However, a few studies have examined the effects of exercise therapy on patients with T2DM undergoing inpatient diabetes self-management education and support (IDSMES). OBJECTIVE: This study investigated whether exercise therapy influenced the incidence of admission after discharge in patients with T2DM undergoing IDSMES. METHODS: This retrospective cohort study included patients with T2DM who underwent IDSMES between June 2011 and May 2015. Overall, 258 patients were included in this study. The exercise therapy program was implemented in June 2013. Accordingly, patients diagnosed between June 2011 and May 2013 were categorized as the non-exercise therapy program group, while those diagnosed between June 2013 and May 2015 were categorized as the exercise therapy program group. Outcomes were incident diabetes-related and all-cause admissions within 1 year of discharge. Multiple logistic regression models were used to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) of the exercise therapy program's impact on the outcomes. RESULTS: Within 1 year of discharge, 27 (10.5%) patients underwent diabetes-related admissions and 62 (24.0%) underwent all-cause admissions. Multiple logistic regression analyses showed a significant association of the exercise therapy program with incident diabetes-related and allcause admissions [OR: 0.22 (95% CI: 0.08-0.59) and 0.44 (95% CI: 0.22-0.86), respectively]. CONCLUSION: Exercise therapy programs significantly lowered the incidences of diabetes-related and all-cause admissions. This indicates that implementing exercise therapy during hospitalization may be important for preventing admissions of patients with T2DM receiving IDSMES.

Relationship between physical activity levels and changes in skeletal muscle characteristics in patients with stroke.

PURPOSE: This study aimed to investigate the relationship between physical activity (PA) levels and short-term changes in skeletal muscle characteristics in patients with subacute hemiparetic stroke. MATERIALS AND METHODS: This prospective observational study included 76 patients with stroke who received inpatient care in a convalescent rehabilitation ward. The PA level was measured as the duration of daily total PA (≥ 1.5 metabolic equivalents) using a triaxial accelerometer for 7 days after admission. The outcomes were changes in the quadriceps muscle quality and quantity on the affected and unaffected sides, as assessed by ultrasonography at admission and 1 month after admission. RESULTS: Multiple regression analysis indicated that the duration of total PA was significantly associated with a percentage change in quadriceps muscle quality (p = 0.011) and quantity (p = 0.012) on the affected side. However, no significant relationship was observed between the muscle quality and quantity on the unaffected side. CONCLUSIONS: The results revealed that PA was associated with changes in the quadriceps muscle quality and quantity on the affected side in patients with subacute hemiparetic stroke. These findings highlight the importance of promoting PA in stroke rehabilitation to improve muscle properties and functional outcomes.

Improving skeletal muscle quality and quantity is an important goal in post-stroke rehabilitation.We investigated physical activity and post-stroke changes in muscle properties.Physical activity is related to changes in muscle quantity and quality on the affected side.Promoting physical activity is essential for improving muscle quantity and quality on the affected side.

A U-shaped relationship between body mass index and functional recovery in older Japanese stroke survivors undergoing hospital rehabilitation.

OBJECTIVE: A relationship between body mass index and functional recovery in older survivors of stroke is unclear. Therefore, this study aimed to investigate the association of body mass index with post-stroke functional recovery in older Japanese stroke survivors undergoing hospital rehabilitation. METHODS: This was a multicenter retrospective observational study of 757 older survivors of stroke, from six convalescent rehabilitation hospitals in Japan. The participants were classified into seven categories according to body mass index at admission. The measurements included outcomes of the absolute gain in the motor subscale of the Functional Independence Measure. Poor functional recovery was defined as gain < 17 points. Multivariate logistic regression analysis was performed to examine the impact of these body mass index categories on poor functional recovery. RESULTS: The mean motor gains were highest in the 23.5-25.4 kg/m2 group (28.1 points), and lowest in the < 17.5 kg/m2 group (220.0 points). The results of the multivariate regression analyses (reference; 23.5-25.4 kg/m2 group) showed that the < 17.5 kg/m2 group (odds ratios 4.30; 95 % confidence intervals 2.09-8.87), the 17.5-19.4 kg/m2 group (1.99; 1.03-3.87), the 19.5-21.4 kg/m2 group (1.93; 1.05-3.54), and the ≥ 27.5 kg/m2 group (3.34; 1.33-8.42) were significantly associated with poor functional recovery, but not in the other groups. CONCLUSIONS: Older survivors of stroke with high-normal weight had the most favorable functional recovery among the seven groups. Meanwhile, both low and extremely high body mass indexes were associated with poor functional recovery.

Diagnosis and prevalence of sarcopenic obesity in patients with colorectal cancer: A scoping review.

BACKGROUND & AIMS: Sarcopenic obesity (SO) is associated with worse outcomes in patients with colorectal cancer (CRC); however, the diagnostic methods and prevalence of SO vary among studies. Therefore, we conducted this scoping review to investigate the diagnosis of SO in CRC, identify the associated problems, and determine its prevalence. METHODS: A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews reporting guidelines. A literature search was performed by two independent reviewers on studies that diagnosed SO in CRC using the MEDLINE, EMBASE, CINAHL, CENTRAL, Web of Science, and Ichushi-Web (in Japanese) databases. Observational, longitudinal, cross-sectional, and clinical trials written in English or Japanese as of July 2022 were included. Studies that did not define SO were excluded from the analysis. The study protocol was pre-registered in Figshare. RESULTS: In total, 670 studies were identified, 22 of which were included. Eighteen studies used sarcopenia in combination with obesity to diagnose SO. Sarcopenia was mainly diagnosed using skeletal muscle mass index (SMI), and only one combined with grip strength or gait speed. Obesity was diagnosed based on the body mass index (BMI; n = 11), followed by visceral fat area (VFA; n = 5). The overall prevalence of SO in patients with CRC was 15% (95%CI, 11-21%). The prevalence of SO in surgical resection and colorectal cancer liver metastases was 18% (95%CI, 12-25%) and 11% (95%CI, 3-36%), respectively. CONCLUSIONS: SO in patients with CRC was mainly diagnosed based on a combination of SMI and BMI, and muscle strength and body composition were rarely evaluated. The prevalence of SO was approximately 15%, depending on the diagnostic methods used. Since SO in patients with CRC is associated with poor prognosis, further research on diagnostic methods for the early detection of SO and its clinical outcomes is needed.

Associations between caregiver burden and care receivers' sharing ratio of household tasks among spousal caregivers.

AIM: We assessed care receivers' sharing ratios of household tasks before they required care and investigated their relationship with caregiver burden. METHODS: A cross-sectional, online survey was completed by 272 spousal caregivers in Japan. Caregiver burden was assessed using the Zarit Burden Interview. Low and moderate-to-high caregiver burdens were defined as those with scores ≤40 and ≥41, respectively. Additionally, caregiver responses to, "How much did your partner contribute to household tasks before the onset of their condition that needed care?" were scored on a 10-point Likert scale ranging from 1 to 10. We defined answers that scored 1-4 as a low sharing ratio and those that scored 5-10 as a high sharing ratio of household tasks of care receivers before developing a condition that required care. RESULTS: Among the husband and wife caregivers, moderate-to-high caregiver burden in 33 (25.0%) and 48 (34.3%) caregivers, respectively. Multivariate logistic regression analysis showed that among the husband caregivers, the high sharing ratio of household tasks of their wives before developing a condition that required care was significantly associated with their caregiver burden (OR 4.55, 95% CI 1.20-17.27); however, no such association was observed among the wife caregivers (OR 0.85, 95% CI 0.37-2.29). CONCLUSIONS: Among husband, but not wife caregivers, the high sharing ratio of household tasks of their wives before they required care was significantly associated with their caregiver burden. Geriatr Gerontol Int 2023; 23: 616-621.

Combination of low muscle strength and malnutrition is associated with longer length of hospital stay among older patients with heart failure.

BACKGROUND: Muscle strength and nutritional status are associated with length of hospital stay (LOHS) in older patients with heart failure (HF). OBJECTIVES: The purpose of the study was to examine the association of the combination of muscle strength and nutritional status on LOHS in older patients with HF. METHODS: This retrospective cohort study included 414 older inpatients with HF (men, 57.2%; median age, 81 years; interquartile range, 75-86 years). Patients were categorized into four groups according to their muscle strength and nutritional status: group 1, high muscle strength and normal nutritional status; group 2, low muscle strength and normal nutritional status; group 3, high muscle strength and malnutrition; and group 4, low muscle strength and malnutrition. The outcome variable was the LOHS, and an LOHS of >16 days was defined as long LOHS. RESULTS: Multivariate logistic regression analysis adjusted for baseline characteristics (reference, group 1) showed that group 4 was associated with a more significant risk of long LOHS (odds ratio [OR], 3.54 [95% confidence interval, 1.85-6.78]). In the subgroup analysis, this relationship was maintained for the first admission HF group (OR, 4.65 [2.07-10.45]) but not for the HF readmission group (OR, 2.80 [0.72-10.90]). CONCLUSIONS: Our results suggest that the long LOHS for older patients with HF at first admission was associated with a combination of low muscle strength and malnutrition but not by either factor individually.

The impact of preoperative muscle strength on postoperative walking ability in patients undergoing total knee arthroplasty.

Although knee extensor muscle strength is strongly associated with postoperative walking ability (PWA) in patients undergoing total knee arthroplasty (TKA), few studies have considered the impact of both knee extensor and flexor muscle strength. This study aimed to determine whether operative side knee flexor and extensor muscle strength before surgery affects the PWA of patients who undergo TKA while accounting for potential covariates. This multicenter retrospective cohort study involved four university hospitals, and patients who underwent unilateral primary TKA were included. The outcome measure was the 5-m maximum walking speed test (MWS), which was completed 12 weeks postoperatively. Muscle strength was measured as the maximum isometric muscle strength required for knee flexor and extensor. Three multiple regression models with a progressively larger number of variables were developed to determine the predictors of 5-m MWS at 12 weeks post-TKA surgery. One hundred thirty-one patients who underwent TKA were enrolled in the study (men, 23.7%; mean age, 73.4 ± 6.9 years). Age, sex, operative side knee flexor muscle strength before surgery, Japanese Orthopaedic Association knee score, and preoperative walking ability were significantly associated with PWA in the final model of the multiple regression analysis ( R2 = 0.35). The current findings suggest that the operative side knee flexor muscle strength before surgery is a robust modifiable predictor of improved PWA. We believe that further validation is needed to determine the causal relationship between preoperative muscle strength and PWA.

Impact of the quantity and quality of the skeletal muscle on survival among patients undergoing allogeneic hematopoietic stem cell transplantation.

INTRODUCTION: Poor skeletal muscle function is relatively high in patients undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT), leading to various negative health outcomes. This study aimed to investigate the relationship between the quantity and quality of skeletal muscle before transplantation and the short-to long-term survival after transplantation in patients undergoing allo-HSCT. METHODS: This retrospective cohort study included 156 patients undergoing allo-HSCT (men, 67.3 %; median age, 53 years; interquartile range, 42-61 years). The quantity and quality of the skeletal muscle were measured at the psoas major at the level of the third lumbar vertebrae using a computed tomography (CT) and were defined as psoas muscle index (PMI) and CT values (CTV), respectively. The outcome measure of this study was overall survival (OS) after allo-HSCT, and we examined the relationship between survival at three time points (6, 12, and 24 months) after transplantation, PMI, and CTV. RESULTS: PMI was significantly associated with survival at all time points in the crude model (P < 0.001), and a significant association was observed in the fully adjusted model (P < 0.01). CTV was significantly associated with survival at all time points in the crude model (P < 0.05), but not in the fully adjusted model (P > 0.05). CONCLUSIONS: We found that the quantity and quality of the skeletal muscle before transplantation were significantly associated with OS at 6, 12, and 24 months after transplantation, showing a particularly robust association with quantity.

Development of a Daily Living Self-Efficacy Scale for Older Adults in Japan.

OBJECTIVES: Older adults tend to experience decreased enjoyment and fulfillment in life, social interactions, and independent living, with aging. These situations often result in lower levels of daily living self-efficacy in activities, which is one of the factors resulting in a decline in the quality of life (QOL) among older individuals. For this reason, interventions that help maintain daily living self-efficacy among older adults may also help maintain a good QOL. The objective of this study was to develop a daily living self-efficacy scale for the elderly that can be used to evaluate the effects of interventions aimed at enhancing self-efficacy. METHODS: An expert meeting involving specialists in dementia treatment and care was held, to prepare a draft for a daily living self-efficacy scale. In the meeting, previous studies on self-efficacy among older adults, which were collected in advance, were reviewed, and the experiences of the specialists were discussed. Based on the reviews and discussions, a draft of a daily living self-efficacy scale comprising 35 items was prepared. This study on daily living self-efficacy was conducted from January 2021 to October 2021. The internal consistency and concept validity of the scale were evaluated based on the assessment data. RESULTS: The mean age ± standard deviation of the 109 participants was 84.2 ± 7.3 years. The following five factors were extracted based on factor analysis: Factor 1, "Having peace of mind"; Factor 2, "Maintaining healthy routines and social roles"; Factor 3, "Taking personal care of oneself"; Factor 4, "Rising to the challenge"; and Factor 5, "Valuing enjoyment and relationships with others". The Cronbach's alpha coefficient exceeded 0.7, thereby suggesting sufficiently high internal consistency. Covariance structure analysis confirmed sufficiently high concept validity. CONCLUSIONS: The scale developed in this study was confirmed to be sufficiently reliable and valid, and when used during dementia treatment and care to assess the levels of daily living self-efficacy among older adults, it is expected to contribute to the improvement of QOL among older adults.

Gender-specific Characteristics of Social Factors Related to Frequency of Daily Conversation Among Community-dwelling Older Adults: A Cross-sectional Observational Study.

Objectives: This study examined the social factors affecting the frequency of going out, and social isolation related to the frequency of daily conversation, stratified by gender. Method: The participants comprised 1,016 community-dwelling older Japanese adults, who were categorized into four groups: those who are (1) not isolated socially and go out every day, (2) not isolated socially and do not go out every day, (3) socially isolated and go out every day, and (4) socially isolated and do not go out every day. We performed a logistic regression analysis to assess the relationship between the frequency of daily conversation and the four groups. Results: Our multivariable logistic regression analysis (reference, group 1) showed that the coexistence of poor social factors significantly affected men (group 2: odds ratio [OR] 2.13 [1.10 to 4.12]; group 3: OR 2.92 [1.70 to 5.00]; and group 4: OR 4.28 [2.43 to 7.54]). For women, the frequency of going out was related to daily conversation only with social isolation group (group 2: OR 1.51 [0.77 to 2.98]; group 3: OR 2.42 [1.25 to 4.68]; and group 4: OR 3.81 [2.08 to 7.00]). Conclusion: Our findings suggest that promoting daily conversations of community-dwelling older adults can help prevent related health adversities.

Effects of Bowel Training and Defecation Posture on Chronic Constipation in Older Adults With Dementia: A Randomized Controlled Trial.

INTRODUCTION: Chronic constipation (CC), which can cause behavioral and psychiatric symptoms of dementia and related caregiver distress, is common in older adults admitted to care facilities with dementia. This study aimed to examine the effect of defecation care on CC and related problems. METHODS: This study compared bowel training and defecation posture intervention (intervention group) with general care (control group) as the treatment of CC among older adults with dementia in 6 long-term care facilities. The primary outcomes were the number of spontaneous bowel movements (SBMs) and complete SBMs. The secondary outcomes were Patient Assessment of Constipation Quality of Life Questionnaire, Constipation Scoring System, constipation symptoms, and Neuropsychiatric Inventory Nursing Home Version scores. The differences were analyzed using 2-way ANOVA with repeated measures. RESULTS: The data of 30 patients (14 in the intervention group, 16 in the control group) were analyzed. Weekly mean complete SBMs increased from 0.53 times at baseline to 1.58 times at 8 weeks in the intervention group compared with a change from 0.56 to 0.43 times in the control group (interaction P < 0.001). The Patient Assessment of Constipation Quality of Life Questionnaire, Constipation Scoring System, behavioral and psychiatric symptoms of dementia, and caregiver distress scores showed significant improvement after 8 weeks of defecation care intervention. DISCUSSION: Defecation care, including bowel training and appropriate defecation posture, is effective for CC among older adults with dementia, improving patient mental health and reducing burden on caregivers.

[Subjective effectiveness and safety of twiddle muff for staff to reduce the wearing of mittens].

PURPOSE: This study investigated the subjective effects and safety of using a twiddle muff to reduce the wearing of mittens by care staff for older patients with dementia. METHODS: A survey was conducted among hospital staff using muffs since January 2022. In addition to the use of questionnaires, the staff were interviewed via the Zoom platform. RESULTS: A total of 18 participants were surveyed, including 15 nurses (83.3%) and 3 physical and occupational therapists (16.8%). Based on the responses to the questionnaire, all participants indicated that the muffs were effective in "removing or reducing physical restraints," and 11 participants (61.1%) pointed out that the muffs were effective in "alleviating behavioral and psychological symptoms" of dementia. The effects of the twiddle muff, as perceived by the staff, were as follows: 1) provides relief from physical and mental tension by reducing mitten restraints and inducing relaxation by pleasant sensory stimulation; 2) improves understanding and allows gentle communication with older patients with dementia; 3) promotes assistance and rehabilitation, enabling transfers and moving operations by reducing the act of clutching bed fences and lines; and 4) is useful as a rehabilitation method for preventing disuse syndrome. CONCLUSION: According to the staff surveyed, the use of the twiddle muff not only eased the distress of older patients with dementia but also helped the respondents understand dementia and promoted communication among themselves. However, it is necessary to objectively demonstrate the effectiveness of a twiddle muff in the future.

[Change in end-of-life care and staff thinking at a geriatric health services facility after the introduction of the "My Wishes" notebook].

AIM: A geriatric health services facility had been working to improve end-of-life care since 2014. In 2017, the facility introduced the My Wishes notebook, which confirms individual's medical choices and distributed the Explaining Practices and Intentions of End-of-life Care book in 2018, in order to help their staff improve care for older adults. Care staff used their learning in caregiving for older adults. This study aimed to clarify the change in end-of-life care and staff thinking at a geriatric health services facility after the introduction of the My Wishes notebook. METHODS: We requested cooperation from all care staff at a geriatric health services facility, and focus group interviews were conducted with 13 staff members over two days in June 2019. The responses in relation to two parameters, the staff members' thoughts and the change in end-of-life care, following the introduction of My Wishes were recorded and qualitatively analyzed. RESULTS: Six categories of responses were extracted from the qualitative analysis: "Difficulty in using My Wishes", "Effects of the use of My Wishes ", "The practice of sought care", "Intentional involvement with patients' families", "Self-confidence in end-of-life care", and "End-of-life care becoming common practice". CONCLUSION: After the introduction of My Wishes, the care staff found that there were difficulties in using My Wishes, such as writing on paper and difficulties in them hearing. On the other hand, they felt the effects of using My Wishes, such as knowing a new side, feeling further possibilities of care, and activating communication among interdisciplinary healthcare providers. Then, while intentionally engaging with patients' families, they will seek and practice the care that the older adults want. Furthermore, while repeatedly searching for and practicing the care that older adults want, they will gain confidence in providing care and change to normalize these care practices.

Care Staff's Daily Living Decision-Making Support Scale for Older Adults with Dementia in Japan: Development of Validity and Reliability.

This study aimed to develop and validate a scale to assess the daily-living decision-making support of care staff for older adults with dementia (OwDs) in Japan. A questionnaire survey was conducted among 138 care staff at two geriatric healthcare facilities from February to March 2021. The Daily Living Decision-Making Support Scale for Older Adults with Dementia (DL-DM) was developed using item analysis, factor analysis, and covariance structure analysis. The factor analysis yielded 12 items and three factors: (1) support for the formation and expression of intentions in daily life based on the life background and values of OwDs; (2) attitudes and devising ways to communicate regarding the formation and expression of intentions in OwDs daily lives; and (3) devising ways to support OwDs in realizing their intentions in daily life. The internal consistency reliability analysis yielded a Cronbach's α of 0.87 for the total scale. The DL-DM correlated with the concurrent validity measures as expected. The DL-DM demonstrated validity and reliability as a potential scale to assess support for OwDs in daily life decision-making. The results also suggest an association between the DL-DM and person-centered care for OwDs.

[Decision-making support for elderly individuals with dementia in a geriatric health service facility: A questionnaire survey on concrete care methods to draw wills of individuals].

PURPOSE: The purpose of this study was to clarify the care methods used by healthcare staff in service facilities to draw up wills for elderly individuals with dementia in daily life and the final stage in decision-making support. METHODS: A questionnaire survey was conducted among healthcare staff in a geriatric health service facility in August 2020. RESULTS: There were 45 subjects (16 males [35.6%]; 29 females [64.4%]). The average age was 42.2 (±12.3) years old, and the mean number of years of experience in a geriatric health service facility was 17.4 (±10.7) years. Deathbed care was provided to ≥90% of the subjects. A factor analysis of items related to decision making in elderly individuals with dementia revealed the first factor to be "support and communication to draw wills", the second factor to be "support and communication for expression to realize decision making", and the third factor to be "understanding, communication, and family support for decision-making realization." The totals of each of these three factors and "having confidence in care focusing on the viewpoint of elderly individuals with dementia" were significantly different. The correction between the Personhood of Approaches to Dementia Questionnaire Japanese version and the three subscales of decision making in elderly individuals with dementia had a significant coefficient of correlation. CONCLUSION: More polite communication methods are necessary for the formation, expression, and realization of the intentions of elderly individuals with dementia to support their decision making.

[Factors related to the awareness of hope at the end of life among older adults who attend community-based preventive services for long-term care].

INTRODUCTION: This study explored the factors related to awareness of hope at the end of life among older adults who attend community-based preventive services for long-term care. METHODS: Hope at the end of life was determined using a six-item questionnaire inquiring about topics such as "Medical hope when oral intake is not possible" and "Where they wanted to spend the end of their lives." A multiple logistic regression analysis was performed using the six items as dependent variables and hospitalization experience, end-of-life care experience, and one's view of life and death as independent variables. RESULTS: Data from 95 retrieved questionnaires were analyzed. The range of hope at the end of life was 14.7%-71.6% for each item. "Where they wanted to spend the end of their lives" was the most frequently considered topic among the respondents. "Medical hope when oral intake was not possible" was considered by 41.1% of respondents, and this topic was related to experience with hospitalization and end-of-life care as well as interest in death. CONCLUSION: Hospitalization experience, end-of-life care, and personal views on life and death were shown to be related to awareness of hope at the end of life among community-dwelling older adults.

The effect of care receivers' dysphagia severity on caregiver burden among family caregivers.

INTRODUCTION: Dysphagia has received much attention as a factor that affects caregiver burden. However, few studies have examined how its severity can affect caregiver burden. This study aimed to examine the effect of dysphagia severity on caregiver burden. METHODS: A cross-sectional online survey was carried out among family caregivers. We assessed caregiver burden using the Zarit Burden Interview. The dysphagia severity was assessed using the Functional Oral Intake Scale, and the caregivers were divided into three groups based on care receivers' oral intake status (levels 1-3: tube-feeding group; levels 4-6: texture-modified food group; level 7: normal group). To investigate the relationship between caregiver burden and dysphagia severity, univariable and multivariable logistic regression analyses were applied to caregiver burden. RESULTS: The Zarit Burden Interview was significantly higher in the texture-modified food group, and the proportions of high caregiver burden reached 25.2%, 39.5% and 23.4% in the normal group, texture-modified food group and tube-feeding group, respectively. The multivariable analyses applied to caregiver burden (reference, normal group) showed that the texture-modified food group was significantly associated with caregiver burden (OR 1.55, 95% CI 1.04-2.32), whereas the tube-feeding group had no relationship with caregiver burden (OR 0.68, 95% CI 0.31-1.49). CONCLUSIONS: Our study showed that the intake of texture-modified food significantly affected caregiver burden even after adjusting for confounding factors, whereas the use of tube feeding did not increase caregiver burden. These results suggest that it is necessary to consider dysphagia severity to reduce dysphagia-related caregiver burden. Geriatr Gerontol Int 2022; 22: 870-875.

The effects of rehabilitation therapy duration on functional recovery of patients with subacute stroke stratified by individual's age: a retrospective multicenter study.

BACKGROUND: The duration of rehabilitation therapy is one of the key elements for promoting post-stroke functional recovery. However, whether an individual's age affects the effectiveness of the duration of rehabilitation therapy on post-stroke functional recovery remains unclear. AIM: This study aimed to investigate whether age has an influence on the relationship between the duration of rehabilitation therapy and post-stroke functional recovery. DESIGN: This is a retrospective observational study. SETTING: Six convalescent inpatient rehabilitation hospitals in Japan. POPULATION: The population of the study was represented by a total of 1186 participants with subacute stroke. METHODS: Participants were stratified into four groups according to their age (≤59, 60-69, 70-79, and ≥80 years). The data of minutes involved in performing rehabilitation therapy for participants during hospitalization per day (extracted from the medical records of each hospital). The outcome measurement was the absolute change in the functional independence measure (FIM) score during hospitalization. RESULTS: The mean FIM gains in the ≤59 years, 60-69 years, 70-79 years, and the ≥80 years groups were 38.7 (18.8), 32.8 (18.0), 29.7 (16.6), and 25.4 (17.2), respectively. The results of the multivariate regression analyses showed that there was a significant association between the duration of daily rehabilitation therapy and the FIM gain in the 70-79 years and the ≥80 years groups (-70-79 years group: B=1.289, ß=0.290, 95% confidence intervals (CIs): 0.718-1.859, P<0.001; the ≥80 years group: B=2.375, ß=0.371, 95% CIs: 1.644-3.107, P<0.001), but not in the other groups. CONCLUSIONS: For patients with subacute stroke in rehabilitation hospitals, a higher duration of daily rehabilitation therapy was associated with better functional recovery in the 70-79 years group and ≥80 years groups. Understanding the responsiveness of patients with stroke to rehabilitation therapy by age group helps to better allocate medical resources and develop more effective approaches. CLINICAL REHABILITATION IMPACT: An increased duration of daily rehabilitation therapy may be helpful in older adults with stroke selected for intensive rehabilitation for improvement of basic daily functioning.
