[Examination of the relationship between tasks in geriatric health service facilities and benefits of working for older assistant care workers].

Objective　In this study, we clarified the characteristics of tasks performed by older assistant care workers at geriatric health services facilities, by individual characteristics and work status. Additionally, we examined the relationship between the tasks and benefits of working for older assistant care workers.Methods　A self-administered questionnaire survey was provided to 2,571 elderly care facilities employing assistant care workers aged ≥60.　A total of 1,606 responses were obtained, and personal characteristics, working conditions, tasks, and benefits of working for older care assistants were surveyed. Thirteen work tasks were established and categorized into four broad categories; user transfer assistance, facility maintenance, meal-related assistance, and managing and talking to users. Seven benefits of working as care assistants were "contribution to society," "social connection," "purpose of life," "income," "learning from caregiving," "health maintenance and promotion," and "time utilization."Results　Most of the respondents were women and relatively young workers. Among tasks, men, younger workers, and those working >5 days weekly represented a high proportion of those performing user transfer assistance tasks. Tasks on managing and talking to users were not correlated with sex, age, and number of days worked, but those with more flexible work patterns were more likely to be engaged in such tasks. Logistic regression analysis showed that user transfer assistance was correlated with benefits of working, such as "contribution to society," "social connection," and "learning from caregiving." Moreover, facility maintenance was associated with "income," "health maintenance and promotion," and "time utilization" and meal-related assistance was associated with "learning from caregiving." Managing and talking to users was associated with "contribution of society," "social connection," "purpose of life," and "learning from caregiving."Conclusion　The tasks of the workers were associated with individual characteristics and work status. The perception of benefits between the working tasks that involved frequent contact with users and those that did not were considerably different.

[Association between the change in the job facilitating and inhibiting factors of care staff due to the employment of older assistant workers and the emotional exhaustion among care staff].

Objectives　The mental health condition of care staff in Japan is becoming problematic. Older assistant workers are currently being employed to assist care staff with their jobs and alleviate their job burden. This employment of older assistant workers is drawing attention; however, their influence on the job facilitating and inhibiting factors of care staff and the association with the care staff's emotional exhaustion remains unclear. In this study, we aim to examine how the employment of older care assistant workers relates to the job-facilitating and job-inhibiting factors of care staff and explore that association with the care staff's emotional exhaustion.Methods　Data from a mail survey of geriatric health services facilities with older assistant workers were analyzed. Among the answers obtained from the care staff, answers from 5,185 who reported working in facilities that employ older assistant workers (over the age of 60) were analyzed. The Emotional Exhaustion subscale of the Japanese Version of the Burnout Questionnaire was used as the dependent variable. The change in job-facilitating and job-inhibiting factors of care staff due to the employment of older assistant workers (improve, maintain/exacerbate) was explored for nine contents.Results　Care staff reported a decrease in the total volume of the task (63.6%), less stress during daily tasks (39.8%), and more concentration on the tasks that require expert care knowledge (38.0%). The results of multiple regression analysis showed that the emotional exhaustion score of care staff was low when the total volume of tasks decreased (ß=－0.383, 95%CI=－0.719, －0.047), when less stress was perceived during daily tasks (ß=－0.432, 95%CI=－0.796, －0.068), when concentration on tasks that required expert care knowledge increased (ß=－0.574, 95%CI=－0.937, －0.210), and when human relationships among staff improved (ß=－0.871, 95%CI=－1.263, －0.480). Conversely, an increase in tasks requiring work with regional personnel and organizations (ß=0.800, 95%CI=0.162, 1.437) was associated with a high emotional exhaustion score.Conclusion　The employment of older care workers was related to the job-facilitating or job-inhibiting factors of care staff, and the change in these factors was associated with lower emotional exhaustion. The employment of older personnel may lower the risk of burnout among care staff.

[Current conditions and challenges of employing older assistant care workers based on geriatric health services facilities' scale].

Objectives　To support care workers, some care facilities employ older individuals as care assistants for peripheral, non-professional tasks. However, the size of the facilities influences their employment needs and support systems for older care workers. Therefore, this study examined the rationale for employing older assistant care workers; the challenges they face; educational systems; and the efforts to facilitate continued employment based on facility size.Methods　Initially, a fax survey was conducted with 3,591 facilities associated with the National Association of Geriatric Health Services Facilities to determine the proportion of older assistant care workers employed. Thereafter, a questionnaire survey was administered to gather more information. Out of 3,591 facilities, 2,170 responded to the survey, and 1,261 responded to the questionnaire. In this study, care assistants aged ≥60 years were classified as older care assistants. The facilities were categorized based on admission capacity into two groups: "small/medium facilities" (≤99 residents) and "large facilities" (≥100 residents). A chi-square test was conducted for data analysis.Results　Of the all geriatric health services facilities, 31.7% employed older assistant care workers. Moreover, the questionnaire survey responses showed they are employed by 687 facilities. Further analysis revealed that larger facilities employed a higher number of older care assistants than small/medium facilities. Small/medium facilities tended to have fewer training systems for older care assistants than larger facilities (30.0% for small/medium facilities vs. 21.6% for large facilities; P=0.014). Furthermore, the work of older care assistants in small/medium facilities was more susceptible to family circumstances than those in larger facilities (15.7% for small/medium facilities vs. 10.2% for large facilities; P=0.033). Compared to small/medium facilities, larger facilities were more likely to state that their employment objective was to reduce the risk of care accidents (19.8% for small/medium facilities vs. 26.3% for large facilities; P=0.046) and provide psychological support, such as periodic interviews, to older care workers to ensure continued employment (24.1% for small/medium facilities vs. for large facilities 37.3%; P<0.001).Conclusion　Larger facilities employeda higher number of older care assistants than small/medium facilities. Furthermore, small/medium facilities were less likely to provide psychological support and had a less structured training system, compared to larger facilities. Additionally, the work of older care assistants in small/medium facilities was more susceptible to family circumstances and other factors, which could affect their work performance. Thus, developing adequate support systems in small/medium facilities is crucial to promoting the employment of older care assistants.

[Relationship between the perceived benefits of working and emotional exhaustion among older assistant care workers: A cross-sectional study].

Objectives　This study is intended to clarify the perceived benefits of working among older assistant care workers employed in geriatric health service facilities and examine the relationship between perceived benefits and emotional exhaustion.Methods　We analyzed data from a mail survey of older assistant care workers employed in geriatric health service facilities that the Japan Association of Geriatric Health Services Facilities conducted in 2020. In this survey, those aged ≥60 were defined as older assistant care workers. Responses were obtained from 1,606 older assistant care workers at 599 facilities. The dependent variable was the emotional exhaustion subscale of the Japanese version of the Burnout Questionnaire. The independent variables were the seven benefits of working as an assistant care worker: 1) I can contribute to society; 2) I am connected to society; 3) I have a sense of purpose in life; 4) I am earning the income I expected since I started working as an assistant care worker; 5) I am learning about care; 6) It has maintained and improved my health; and 7) I can use my time effectively. Latent class analysis (LCA) was performed using these seven benefits as independent variables. Multiple regression analysis was performed using emotional exhaustion and the perceived benefits as dependent and independent variables, respectively. The missing values were supplemented by the multiple imputation method.Results　Overall, 1,601 responses were analyzed after excluding 5 respondents who did not answer all the questions. Four patterns were identified from the LCA results: the "benefit-full type," who perceived all benefits; the "benefit-less type," who perceived few benefits; the "benefit-extroverted type," who perceived social contribution and connection as benefits; and the "benefit-introverted type," who perceived health maintenance and improvement and time utilization as benefits. The multiple regression analysis showed that emotional exhaustion scores were higher for the "benefit-extroverted" and "benefit-less" types than for the "benefit-full" type (b=2.465, P<.001 and b=1.931, P<.001, respectively). No difference was found in the case of the "benefit-introverted" type (b=0.050, P=.851).Conclusion　The perceptions of diverse and introverted benefits were associated with lower emotional exhaustion scores among older assistant care workers. Future intervention studies are needed to examine whether obtaining diverse or introverted benefits can decrease the emotional exhaustion score.

Relationship between oral health and prognosis in patients with empyema: Single center retrospective study with propensity score matching analysis.

BACKGROUND: Empyema is a life-threatening infection often caused by oral microbiota. To the best of our knowledge, no reports have investigated the association between the objective assessment of oral health and prognosis in patients with empyema. MATERIALS AND METHODS: A total of 63 patients with empyema who required hospitalization at a single institution were included in this retrospective study. We compared non-survivors and survivors to assess risk factors for death at three months, including the Renal, age, pus, infection, diet (RAPID) score, and Oral Health Assessment Tool (OHAT) score. Furthermore, to minimize the background bias of the OHAT high-score and low-score groups determined based on the cut-off value, we also analyzed the association between the OHAT score and death at 3 months using the propensity score matching method. RESULTS: The 3-month mortality rate was 20.6% (13 patients). Multivariate analysis showed that a RAPID score ≥5 points (odds ratio (OR) 8.74) and an OHAT score ≥7 points (OR 13.91) were significantly associated with death at 3 months. In the propensity score analysis, a significant association was found between a high OHAT score (≥7 points) and death at 3 months (P = 0.019). CONCLUSION: Our results indicated that oral health assessed using the OHAT score may be a potential independent prognostic factor in patients with empyema. Similar to the RAPID score, the OHAT score may become an important indicator for the treatment of empyema.

Employment in old age and all-cause mortality: A systematic review.

Social participation promotes and maintains the health of older adults. Working is a type of social participation; however, the effect of employment in old age on health outcomes has not been established. This study aimed to review the relationship between employment in old age (≥60 years) and all-cause mortality. For this systematic review, a computerized search was performed using PubMed, CINAHL and PsycINFO for prospective studies published through June 2020. The observational studies were extracted according to the study participants, indicators, follow-up period, statistical approach and main results. The quality of the studies was assessed using the Newcastle-Ottawa Scale. Of the 37 832 records identified, 14 studies were included in the systematic review based on the inclusion and exclusion criteria. Eight studies were derived from Asian countries (four from Japan, two from Taiwan and one from Thailand and South Korea), three were from the United States, two were from Israel and one was from Brazil. The baseline data of 13 studies were collected before 2000. Thirteen of the 14 studies reported any association between employment in later life and a lower risk of mortality. Four studies examined the sex-related differences in the effect of later-life employment on all-cause mortality, but the association was controversial. Overall, we revealed that working in old age would lower mortality risk. Although more findings based on recent data are required, this study indicates that working later in life is beneficial for promoting and maintaining health. Geriatr Gerontol Int 2022; 22: 705-714.

[Actual work situation of second-layer Seikatsu-shien coordinators before and after the first emergency declaration during the COVID-19 pandemic].

Objective　This study aims to understand the status of the resident support activities of second-layer Seikatsu-shien coordinators, who assist in local residents' community development activities, based on long-term care. It observes the effects of these activities, and the presence or absence of relevant instructions from the government or affiliated institutions during and after a state of emergency, such as a lockdown situation. This was examined during the first state of emergency following the COVID-19 crisis, from April to May 2020.Method　In October 2020, a self-administered questionnaire was distributed by mail to 279 second-layer Seikatsu-shien coordinators working in Tokyo's special wards, and 181 responses were collected. The survey focused on the coordinators' activities and activity frequency before the spread of COVID-19, during the state of emergency, and after the activities resumed. Furthermore, the survey questioned whether relevant instructions from the government or affiliated institutions were given during the state of emergency and after the activities resumed. Their details were confirmed in the free comments section.Activity　In creating and revising regional diagnosis tables for the area covered, creating and distributing information magazines and leaflets, etc. included in "understanding social resources and providing information to relevant parties," activity frequency was significantly higher after activities resumed, than before the spread of infection. During the state of emergency, activity frequency was high in the affiliated institution, and only 3.4% of the coordinators visited and spoke to local residents; 91.1% of respondents received instructions from government and affiliated institutions during the state of emergency, and activity frequency was significantly higher when there were instructions; 76.5% received instructions after resuming activities, and activity frequency, such as understanding residents' needs through individual interviews and visits, matching them with services, and supporting the resumption of activity groups was significantly higher when instructions were provided.Conclusion　 After resuming activities, understanding the value of social resources and providing information to the relevant parties was prioritized. During the state of emergency, almost no visits or calls were made to local residents. The frequency of activities to reach out to residents was higher in the presence of instructions, especially after activities resumed. It was suggested that with the rapid spread of a new infectious disease, confusion will likely occur in the field, and having specific instructions will affect the Seikatsu-shien coordinators' activities.

[Relationship between local seniors' longest-held occupation, current work situation, and reasons for working].

Objective　The purpose of this study was to clarify how the type and industry of longest-held occupations correlate with current work situations and reasons for working.Methods　In August 2015, we mailed anonymous, self-administered questionnaires to all 8,075 residents aged 65 and over of a district in Ota Ward, Tokyo, excluding those admitted to institutions. The questionnaire inquired about their basic attributes, current employment status, as well as the type of work and industry of their longest-held occupation. Furthermore, those who were currently employed were asked about their reasons for working. We conducted a multinomial logistic regression analysis with the current employment situation as the dependent variable, and a binary logistic regression analysis with the applicability of individual reasons as the dependent variable.Results　A total of 5,184 questionnaires were returned (response rate: 64.2%), and 5,050 were analyzed. For the longest-held form of work, the most common response was full-time and part-time employment (42.7%), and the most common industry was sales and service (24.2%). Roughly 30% of respondents were currently working, with the most common reason being "For a living," followed by "For my health," "To have a purpose in life (ikigai)," and "To contribute to society and build connections." The industry of the longest-held occupation for those currently working was most often self-employment; executive roles in independent businesses, companies, or organizations for those in full-time positions; and professional jobs for those working part-time. For those not currently working, most had been full-time employees or unemployed. With regard to the longest-held occupations, those currently working and who gave the reason "For a living" were most often owners of independent businesses or self-employed, while those stating "For my health," "To have a purpose in life," and "To contribute to society and build connections" had often been full-time employees, executives at a company or organization, or in administrative or technical positions.Conclusion　For seniors' employment or social participation to go smoothly, we believe a support that emphasizes individuality would be effective, including an emphasis on their longest-held occupation, which is deeply connected to their health conditions and quality of life in old age.

[Longitudinal association between work and self-rated health in older adults: a systematic review].

Objective　Japan's shortage in labor force due to a declining birth rate and aging population has led to the rapid development of various systems and work environments to promote the employment of older adults. With increasing expectations for the active participation of older adults in the labor market, it is necessary to clarify the relationship between work and physical and mental health in this population, as well as the challenges they face. In particular, self-rated health is an important health indicator that captures the overall health status of older adults, which is strongly related to the decline in life functions and the increase in healthy life expectancy. In this study, we examined the longitudinal association between work and self-rated health perception among older adults.Methods　A literature search was conducted using PubMed, PsycINFO, CINAHL, and the Japana Centra Revuo Medicina (Igaku Chuo Zasshi in Japanese). The keywords selected for the search were "older adult," "employment," and "self-rated health." The inclusion criteria were i) the baseline age of study subjects was 60 years or older, ii) employment was used as an independent variable and self-rated health was used as a dependent variable, and iii) studies were longitudinal. The quality of the selected literature was assessed using the Newcastle-Ottawa Scale (NOS).Results　As a result of the review, a total of five studies were accepted. Four studies were from Japan and one was from the United States. The NOS scores showed that all selected studies were of high quality, scoring 6 or 7 on a 9-point scale. Three of the five studies reported that older adults who were working had higher self-rated health than those who were not working. Two of the five studies reported no significant association between employment and self-rated health among older adults.Conclusion　This systematic review suggested a significant relationship between work and self-rated health among older adults. However, the number of studies that focused on the longitudinal effect of employment was limited. Employment in later life is becoming increasingly common, therefore further evidence on its effect on health should be gathered.

Associations between Depressive State and Impaired Higher-Level Functional Capacity in the Elderly with Long-Term Care Requirements.

Depressive state has been reported to be significantly associated with higher-level functional capacity among community-dwelling elderly. However, few studies have investigated the associations among people with long-term care requirements. We aimed to investigate the associations between depressive state and higher-level functional capacity and obtain marginal odds ratios using propensity score analyses in people with long-term care requirements. We conducted a cross-sectional study based on participants aged ≥ 65 years (n = 545) who were community dwelling and used outpatient care services for long-term preventive care. We measured higher-level functional capacity, depressive state, and possible confounders. Then, we estimated the marginal odds ratios (i.e., the change in odds of impaired higher-level functional capacity if all versus no participants were exposed to depressive state) by logistic models using generalized linear models with the inverse probability of treatment weighting (IPTW) for propensity score and design-based standard errors. Depressive state was used as the exposure variable and higher-level functional capacity as the outcome variable. The all absolute standardized differences after the IPTW using the propensity scores were < 10% which indicated negligible differences in the mean or prevalence of the covariates between non-depressive state and depressive state. The marginal odds ratios were estimated by the logistic models with IPTW using the propensity scores. The marginal odds ratios were 2.17 (95%CI: 1.13-4.19) for men and 2.57 (95%CI: 1.26-5.26) for women. Prevention of depressive state may contribute to not only depressive state but also higher-level functional capacity.

Association between subjective memory complaints and impaired higher-level functional capacity in people aged 60 years or older.

OBJECTIVE: We aimed to investigate the association between subjective memory complaints and higher-level functional capacity in either people with long-term care needs or those who require help to maintain functional capacity. METHODS: We conducted a cross-sectional study among participants aged 60 years or older. We measured subjective memory complaints, higher-level functional capacity, and depressive symptoms, and then estimated odds ratios (ORs) by multiple logistic analysis. Subjective memory complaints were used as the predictor variable, higher-level functional capacity as the outcome variable, and age, depressive symptoms, medical history of diabetes and hypertension, frequency of going out, falling within a year, and body mass index as possible confounders. We assessed higher-level functional capacity using the Tokyo Metropolitan Institute of Gerontology (TMIG) index of competence score ≤5 as a cut-off (which is associated with higher one-year mortality rates). RESULTS: We conducted analyses using 501 people aged 60 years or older. Among women, subjective memory complaints were associated with impaired higher-level functional capacity after adjustment for age and depressive symptoms (OR=3.36; 95% confidence interval [CI], 1.59-7.08). Among the men, subjective memory complaints were not significantly associated with impaired higher-level functional capacity after adjustment for age and depressive symptoms (OR=1.91; 95% CI, 0.88-4.12). CONCLUSIONS: Subjective memory complaints among women can indicate impaired higher-level functional capacity and may suggest higher one-year mortality rates.

[Nutcracker syndrome treated by endovascular stenting of the left renal vein].

We describe endovascular stenting of the left renal vein to treat Nutcracker syndrome accompanied by gross hematuria. A 26-year-old woman with a history of hematuria and left flank pain was admitted to another hospital in January 2009. She was referred to our hospital in August 2010 for further investigation and treatment for suspected Nutcracker syndrome based on her medical history and the recurrent gross hematuria. Computed tomography (CT) imaging revealed compression of the left renal vein between the aorta and the superior mesenteric artery and cystoscopy revealed bloody urine from the left ureteric orifice. Ureteroscopy revealed diffuse bleeding from the renal pelvic mucosa. The cytodiagnosis of urine was Class II. She developed left flank pain and further recurrent hematuria in July 2011 and sought active treatment by stenting at our hospital. After we obtained the approval of the Ethical Review Board in our institution, we treated by endovascular stenting of the left renal vein. The venous phase of selective renal angiography during the procedure revealed dilation of the mid-renal vein with delayed flow into the inferior vena cava and tortuous dilated collateral vessels. Two ELUMINEXX Vascular Stents (12 x 40 mm) were deployed at the stenotic site of the left renal vein via the right femoral vein. This strategy improved the stenosis and collateral vessels. No significant postoperative adverse events developed other than dull back pain that disappeared after a few days, and the patient was discharged on postoperative day 4. CT findings three months after the procedure confirmed resolution of the left renal vein compression. Six months post-procedure, the patient had no left flank pain or further hematuria.

[Gender differences in caregiving experience changes over 2-years and effects on psychological well-being of spousal caregivers in a longitudinal study].

PURPOSE: We examined spousal gender differences in change of caregiving experience over 2-years, focusing on care-recipient's physical and mental conditions, living arrangements, financial status, utilization of long-term care insurance (LTCI), availability of secondary caregivers, caregiver's coping strategies and psychological well-being. We also investigated causal associations between caregiving experiences and psychological well-being of the spousal caregivers. METHOD: We conducted a 2-wave survey, in Oct. 2003 and 2005. The subjects were a stratified random sample of 5,000 users of LTCI in Higashi-osaka city in Japan. Data were collected through mailed, anonymous self-report questionnaires. Totals of 212 wives and 356 husbands were longitudinally analyzed. A cross-lagged effect model by simultaneous analysis of multiple populations was made to analyze a causal association between caregiving experiences and caregivers' psychological well-being. RESULTS: There were no significant changes in care-recipient's physical and mental conditions. Over the 2 years, husbands increased the amount of ADL assistance and availability as secondary caregivers, and wives increased utilization of LTCI services. We also found gender differences in the priority of coping strategies. Husbands' preferred coping strategy over 2 years was more on 'willing commitment caregiver's role 'while for wives' it was 'instrumental support seeking'. Wives demonstrated a significantly reduced positive appraisal of caregiving. Though the amount of ADL assistance and 'instrumental support seeking' reduced husband's depression, husband's positive appraisal of caregiving significantly increased strategies of 'emotional support seeking' and 'willing commitment of care role'. Wives & depression decreased with 'valuing own leisure and refreshing' strategies. Furthermore, wives' positive caregiving appraisal increased both strategies of 'keeping own pace of caregiving' and willing acceptance of care role'. CONCLUSION: The husband's results support an interpretation of adaptation to the caregiving role over two years. Therefore husbands who do not experience increase in ADL assistance might be at risk of caregiver's depression. We should monitor their situation of caregiving continually. Though wives increased utilization of LTCI services, this service use did not improve their psychological wellbeing, and they exhibited decreased positive appraisal of caregiving.

[Development of a scale for work motivation of home care workers and influencing factors].

PURPOSE: To develop a scale for home care workers focusing on work motivation and to determine influential underlying factors. METHODS: This study was an anonymous mailed survey of home care workers who provided home help services in July 2007. We collected information in the following areas: demographics of home care workers and care-recipients, burnout, stress, job satisfaction, life satisfaction, and self-esteem (SE). Hierarchical regression analysis was performed in order to identify factors related to work motivation. RESULTS: Construct validity was analyzed by factor analysis. Two subscales were obtained by the analysis and designated as "positive appraisal of the current state" (9 items) and "uplift of morale" (3 items). Content validity was analyzed by good-poor and item-total, and all correlations were strongly positive. Reliability was analyzed by internal consistency. Cronbach's ? values were 0.94 and 0.77, respectively. Concurrent validity was analyzed by correlation coefficient and a significant negative correlation was seen between the two subscales and burnout (r = -0.23--0.50), while positive correlations were noted for job or life satisfaction (r= 0.24-0.49). The positive influential factors on "positive appraisal of the current state" were satisfaction in 1) relation to care-recipients, 2) work environment for skill improvement and 3) the wages. The positive influential factors on "uplift of morale" were satisfaction with relation to care-recipients and their own life. CONCLUSIONS: This scale has sufficient reliability and validity. "Positive appraisal of the current state" and "uplift of morale" were confirmed as appropriate work motivation subscales for home care workers. Thus, support to augment job satisfaction with the work environment and wages appears to enhance "positive appraisal of the current state" and support to augment life satisfaction appears to enhance "uplift of morale".

Gender differences in spousal caregiving in Japan.

BACKGROUND: Gender differences in spousal caregivers and their relationship to care experiences, social demographics, and caregivers' depression were examined. METHODS: A stratified random sample of 2,020 users of public long-term care insurance in a city of Osaka prefecture, Japan, participated in this study. Responses from 308 spouses (56.2% wives, 43.8% husbands) were analyzed. Variables relating to care experiences, social demographics, and caregivers' depression were compared by conducting simultaneous analyses of multiple populations. RESULTS: Wives caring for husbands had higher depression scores than husbands caring for wives. Wives tended to adopt "emotional support seeking" and "willing commitment" as coping strategies for their caregiving experience. Husband caregivers used more home-care services; however, increased service use had no effect on husbands' depression. The availability of secondary caregivers reduced depression for caregivers, regardless of gender. CONCLUSIONS: The effects on depression differed related to the caregiver's gender. Husbands relied more on family or home-care services when caring for their wives, whereas wives provided higher levels of care, positively accepted their role, and did not seek to share caregiving, but sought emotional support.

Management of behavioral and psychological symptoms of dementia in long-term care facilities in Japan.

BACKGROUND: An increasing number of old people, and their medical requirements, cannot be managed by their families in their homes, which has been the traditional and prevalent practice in Japan. The number of people with dementia is increasing and behavioral and psychological symptoms of dementia (BPSD) make care difficult. In the present study, we investigated management techniques for BPSD in long-term care facilities in Japan by using the data mining method, which looks at the reported behaviors of care providers. METHODS: First, interviews were conducted with 15 care providers to develop items for a questionnaire. These data were analyzed qualitatively and synthesized with criteria from the professional literature. The resulting self-report questionnaire on techniques used to manage different symptoms of dementia was completed by 275 care providers. We applied the association rule as a data mining method examining 15 management techniques related to 13 BPSD. RESULTS: Analysis identified four types of management techniques: (i) emotional and behavior-concordance techniques; (ii) acceptance and supportive techniques; (iii) restraining techniques; and (iv) avoidance techniques. Different management techniques, and combinations of techniques, were found to vary in use and effectiveness with different BPSD. CONCLUSIONS: Good management techniques for many BPSD have been developed and are being implemented by care providers. The present study has the potential to inform researchers and care providers in Japan about the types of management techniques in current use, as well as areas of potential need for staff training.

[Family caregiver burden caused by behavioral and psychological symptoms of dementia: measurement with a new original scale].

AIM: The purpose of this study was to measure the caregiver burden caused by behavioral and psychological symptoms of dementia (CBBD) using an originally developed scale and to estimate the CBBD scores in a large sample of family caregivers of elderly people. METHODS: The subjects were 1,818 users of the public Long-term Care Insurance, randomly stratified and sampled in Higashi-osaka city, Osaka prefecture. Data were collected through mailed, anonymous self-report questionnaires. The survey was conducted in October 2003. We created a 10-item CBBD scale based on previous studies on caregivers of dementia. The CBBD scale was applied to all caregivers regardless of dementia symptoms, and we also collected the following information: demographic data of the care-recipients and caregivers, the level of cognitive disorders of the care-recipient and the overall subjective caregiver burden. RESULTS: All items of the CBBD scale were selected at higher percentages by caregivers of care-recipients with cognitive disorders than caregivers of care-recipients without cognitive disorders. In particular, the relative risk and odds ratio of caregivers of care-recipients with cognitive disorder was higher in items such as 'the caregiver feels fear and anxiety about the care-recipient's unpredictable behavior', 'the care-recipient doesn't understand what the caregiver says', 'the caregiver feels irritated with incomprehensible care-recipient's behavior' which pose psychological stress or pressure on caregivers. On the other hand, the relative risk and odds ratio of the overall subjective caregiver burden was lower than that of any item of the CBBD scale. Furthermore, all CBBD items were related to symptoms of dementia (aroused/paranoid behavior, memory disorder, cognitive dysfunction, pica behavior). CONCLUSION: The CBBD scale had sensitivity for the care-recipient's cognitive disorder. In addition, it can detect more precisely the caregiver burden such as psychological stress or pressure due to the care-recipient's cognitive disorders, and it is also useful to assess the needs of caregivers who care for elderly family members with dementia.
