Kimie Fujita, Kiyoko Makimoto, Yasuko Tabuchi, Yuriko Matsunaga-Myoji, Masaaki Mawatari, Oxford hip scores, floor-sitting score trajectories, and postoperative satisfaction rates at 10 years after primary total hip arthroplasty, J Arthroplasty ., 10.1016/j.arth.2023.06.016., 1-7, 2023.07, Background: Available evidence on outcomes at 5 years and beyond for total hip arthroplasty (THA) is mainly limited to patient-reported outcome measures (PROMs). This study documented the trajectory of functional measurement using the Oxford hip score (OHS) and floor-sitting posture in Japan for up to 10 years post- THA and investigated predictors of dissatisfaction at 10 years with THA.

Methods: Patients scheduled for primary THA at a university hospital in Japan between 2003 and 2006 were enrolled in this prospective study. Overall, 826 preoperative participants were eligible for follow-up, with response rates ranging from 93.6 to 69.4% at each postoperative survey point. The OHS and floor-sitting scores were calculated using a self-administered questionnaire six times up to 10 years postoperatively. Patient satisfaction, including general surgery, walking ability, and activities of daily living (ADL), was assessed in the 10-year survey.

Results: The linear mixed-effects model demonstrated a postoperative improvement, peaking at 7 years for OHS and 5 years earlier for the floor-sitting score. The postoperative overall surgical dissatisfaction at 10 years with THA was very low (3.2%). No predictors of surgical dissatisfaction were identified in the logistic regression analyses. Predictors of walking ability dissatisfaction were older age, men, and worse OHS at 1 year postoperatively. Predictors of ADL dissatisfaction were poorer preoperative and 1-year postoperative floor-sitting scores and 1-year postoperative OHS.

Conclusion: The floor-sitting score is a simple PROM suitable for the Japanese population; other populations would require a scale suitable for their lifestyles.

Keywords: Oxford hip score; floor-sitting score; postoperative satisfaction; total hip arthroplasty..

Sayori Sakanashi, Kimie Fujita, Midori Nishio, Shinji Ouma, Kumiko Ogata, Learning needs of family caregivers in the Japanese working generation who care for community-dwelling people with dementia: A qualitative research study, Journal of International Nursing Research, 10.53044/jinr.2021-0022, 1-10, 2023.04, Objective: This study investigated and described the learning needs experienced by family caregivers in the Japanese working generation who care for community-dwelling people with dementia (PWD). Methods: This qualitative descriptive study conducted semi-structured in-depth interviews to explore the learning needs experienced by the family caregivers of PWD. 18 family caregivers were recruited via purposive sampling (age range 30-60 years) from two medical facilities, two self-help groups, and 10 prefectural-sponsored counseling facilities in Japan. The collected data were subjected to a qualitative content analysis. Then, the derived learning needs were independently reviewed by two nursing researchers with expertise in qualitative research and family nursing. The Standards for Reporting Qualitative Research (SRQR) recommendations were followed. Results: Four main categories and 20 subcategories were derived to clarify the learning needs of family caregivers in the Japanese working generation who care for community-dwelling PWD. The four main categories included (a) increasing long-term care literacy, (b) dispelling the negative images associated with dementia and long-term care, (c) working on long-term care as a unified team that handles issues concerning caregiving for dementia, and (d) promoting an active role as a member of society. Conclusions: This study clarified specific learning needs that family caregivers in the Japanese working generation experience when caring for community-dwelling PWD, thus, contributing to a more thorough understanding of the associated challenges. In addition, the structured list of learning needs should aid health professionals when conducting assessments and planning interventions, especially when framing these issues from the cultural perspective..

Aim: Total hip arthroplasty can effectively improve patients' motility with
end-stage osteoarthritis. This study aimed to: (1) compare gradual changes in
utility values with total hip arthroplasty and estimated values without; (2) evaluate
total hip arthroplasty cost-effectiveness; and (3) evaluate cost-effectiveness
by age, diagnosis, and comorbidity.
Methods: Patients who underwent total hip arthroplasty between January
2008 and December 2009 were included. Patients completed the EuroQol preoperatively
and at 1, 3, 5 and 7 years postoperatively. To derive the qualityadjusted
life years gained, a utility score was obtained from the EuroQol item
scores and combined with 7 years, and estimates were obtained by discounting
the postoperative 1-year utility value at an annual rate of 2%–4%. Mixed-effects
regression models were used to compare the estimated and the measured utility
Results: Mean total cost was 1,921,849 yen, and quality-adjusted life years
gain score was 1.746 with per cost as 1,100,715 yen. Compared with actual
measurements, the estimated values from 1 to 7 years post-surgery differed significantly,
and interaction was observed. Regarding age, the older the patient,
the higher the cost per quality-adjusted life years. Patients with lower preoperative
physical function had higher quality-adjusted life years gains, while the
cost per quality-adjusted life years was lower.
Conclusions: Total hip arthroplasty was cost-effective. Compared with actual
measurements, the estimated utility values from 1 to 7 years post-surgery significantly
differed. Even among older patients and those with impaired preoperative
physical functions, its cost was lower than patients' willingness to pay
in Japan..
6. Rumi Tanaka,Kanako Yakushiji, Satomi Tanaka, Michihiro Tsubaki, Kimie Fujita, Reliability and Validity of Light-Intensity Physical Activity Scales in Adults: A Systematic Review, Measurement in Physical Education and Exercise Science , 10.1080/1091367X.2022.2120356, 27, 2, 136-150, 2022.09, This study aimed to review the validity and/or reliability of light-intensity physical activity (LPA) questionnaires and identify the most suitable questionnaires for measurement of LPA in adults. Following the PRISMA-P 2020 guidelines, we searched MEDLINE, PsycINFO, CINAHL, Scopus, Embase, and MedNar. Only studies that targeted adults ≥18 years old and used LPA measured by accelerometer and/or heart rate monitor as an objective criterion were included. The search resulted in 2748 article hits, from which we extracted 16 studies with 14 questionnaires. The 7-Day Sedentary and LPA Log and LPA Questionnaire were specifically designed for LPA measurement, and the Community Health Activities Model Program for Seniors physical activity self-report questionnaire scale has been revised for LPA measurement. These questionnaires had comparatively high reliability and validity in this review. Most studies contained methodological limitations such as test-retest period. In the future, more accurate reliability/validity studies should be conducted for each questionnaire..

Satomi Tanaka, Kimie Fujita, Kanako Yakushiji, Noboru Harada, Tomoharu Yoshizumi, Changes in Physical Activity Due to Fear of COVID-19 and Its Impact on Depression Among Post-Liver Transplant Patients in Japan: A Longitudinal Survey Study, Ann Transplant, 10.12659/AOT.938239, 27, 1-9, Ann Transplant 2022; 27:e938239, 2022.12, BACKGROUND Regular physical activity (PA) is important for maintaining mental and physical health after liver transplantation (LT); however, the fluctuations in routine PA during COVID-19 and its putative impacts are currently unknown. This study examined the changes in PA during the COVID-19 pandemic and explored its association with fear and depression during the pandemic. MATERIAL AND METHODS This longitudinal study included 83 LT patients whose PA was measured using the short form of the International Physical Activity Questionnaire before and during COVID-19. Fear of COVID-19 was estimated based on previous studies, and depression was assessed using the Patient Health Questionnaire-9. Participants were also asked about important sources of information on COVID-19. PA was classified as inactive or active depending on the changes in PA, and logistic regression analyses with PA as a dependent variable were conducted to explore the associations among PA, depression, and fear of COVID-19. RESULTS Moderate and high PA exhibited decreasing trends before and during the COVID-19 pandemic, especially in males. Fear of being infected with SARS-CoV-2, the virus that causes COVID-19, while shopping was significantly higher in females and was significantly independent of inactivity during the COVID-19 pandemic. Only 1 patient reported that their transplant center was their main source of information about COVID-19. Only 4.9% of the LT participants were depressed. CONCLUSIONS Our study results indicate the need to support the provision of accurate information about COVID-19 by health care professionals in transplant centers, especially for patients with low PA, to prevent PA decline in LT patients..

Rumi Tanaka,Kimie Fujita,Satoko Maeno,Kanako Yakushiji,Satomi Tanaka, Keizo Ohnaka, Kenji Ashida, Shohei Sakamoto, Masatoshi Nomura, The effect of real-time monitoring of physical activity intensity in diabetic patients, Japan Journal of Nursing Science, 10.1111/jjns.12445, 19, 1, 1-10, 2021.08, Aim: To evaluate the effects of an intensity display type accelerometer on diabetic patients' physical activity.

Methods: This was a two-arm, non-randomized controlled study. Both groups received information about the recommendation of 150 min/week moderate-to-vigorous physical activity (MVPA). The intervention group used an intensity display type accelerometer to monitor their physical activity intensity for 10 days at baseline and 3 months later. We compared intervention and control groups after 3 and 6 months. Primary outcomes were MVPA and number of steps over 7 days. Secondary outcomes were glycosylated hemoglobin (HbA1c), body mass index, and self-management.

Results: Of 62 participants, 30 and 32 were included in the intervention and control groups, respectively. Mean age in each group was 59.7 ± 10.8 and 58.8 ± 10.2 years, and mean HbA1c was 6.9 ± 0.9% and 6.9 ± 0.8%, respectively. There were no significant differences between the intervention and control groups at either time point, and no outcomes showed significant changes. In a subgroup analysis by physical activity intensity, MVPA of active individuals in the control group significantly decreased at 6 months from baseline. MVPA and number of steps among inactive individuals in the intervention group significantly increased at 6 months from baseline. Self-management of the intervention group showed a trend toward improvement, but HbA1c and body mass index showed no significant change.

Conclusions: Monitoring physical activity intensity led to increased MVPA of inactive patients and maintained MVPA of active patients with diabetes mellitus. This straightforward intervention could be applied in clinical practice..

A semi-structured interview was conducted among examinees with abnormal glucose levels who had never visited a medical clinic for diagnosis of hyperglycemia. Patients were divided into two segments. A tailored notification letter was developed according to these segments using a social marketing approach. Other examinees were prospectively enrolled as the control group. The tailored notification for Segment 1 included a web code to access a health care provider. Future loss of time and money was emphasized in the message for Segment 2. According to responses in a telephone interview, 654 examinees with abnormal fasting glucose levels in a health checkup were divided into Group 1 (n = 178), Group 2 (n = 24), and a control group (n = 452) and given a tailored or conventional notification letter. The proportion of examinees who actually visited a health care provider in Group 1 (20.8%) was significantly higher than that in the control group (11.1%); no examinees in Group 2 visited a health care provider. Receipt of a tailored notification was a significant factor associated with visiting a health care provider, independent of age, sex, or severity of glucose abnormality (odds ratio 1.77; p = 0.02). Our results showed that tailored notification developed using a social marketing approach prompted health checkup examinees with abnormal glucose levels to seek medical care..

We aimed to assess PA in post‐LT patients and to quantify its relationships with the development of postoperative metabolic abnormalities and health‐related quality of life (HRQOL). We recruited 111 patients who had undergone LT ≥ 6 months previously. PA was measured by accelerometry, and HRQOL was evaluated using SF‐8. PA was quantified as the number of steps per day, and the time spent performing moderate‐to‐vigorous PA and light PA per week. The prevalence of hypertension, diabetes, and dyslipidemia increased more than twofold following LT. The proportion of the participants with a sedentary lifestyle (

Kiyoko Makimoto, Kimie Fujita, Rie Konno, Review and synthesis of the experience of patients following total hip or knee arthroplasty in the era of rapidly decreasing hospital length of stay, Japan Journal of Nursing Science, 10.1111/jjns.12361, 17, e12361, 2020.08, Aim: The hospital length of stay for orthopedic surgery has been decreasing during the last couple of decades. Therefore, this study was performed to explore the postoperative experiences of adult/older patients (age ≥20 years) with osteoarthritis who underwent total hip or knee arthroplasty, focusing on the first 6 weeks following discharge. Methods: A systematic literature search on qualitative studies was conducted using six databases, such as Medline, CINAHL and Mednar. Verbatim interview data and themes or subthemes related to the patients' experience after discharge were extracted. Content analysis was used to code interview data. Codes similar in meaning were grouped, and subcategories were formed. These subcategories were then grouped into categories. Results: Sixteen qualitative studies with 253 participants were analyzed. In total, 136 codes were generated and formed 29 subcategories. Six categories were generated: (a) postoperative pain and medication; (b) difficulty in performing activities of daily living; (c) appreciation for support and difficulties associated with receiving support; (d) variability in recovery process and information-seeking; (e) lack of patient-centered care; and (f) transportation problems and social isolation. Conclusion: Our review suggests that prospective patients and their caregivers need individually tailored presurgical education and advanced planning for postsurgical reduced mobility..

Methods: Patients over 20 years of age who were undergoing LDLT were recruited. PA was measured based on the number of steps/day and time spent performing moderate-to-vigorous PA (MVPA) during 1 week using an accelerometer. QOL was assessed based on a physical (PCS) and mental (MCS) component summary of the eight-item Short-Form Health Survey. The LDLT and healthy control groups were matched for age (±3 years) and gender. Pre-operative factors predicting a change in PA were calculated using a generalized linear mixed model. Results: Twenty-four patients completed the study. By 6 months post-LDLT, the MCS and PCS were comparable to those in the control group. The number of steps (3,887 steps/day) and MVPA (29.3 min/week) showed significant improvement by 6 months post-operatively, but remained much lower compared with those in the control group. The multivariate analysis showed that younger age (p <.01 p=".04)" and higher skeletal muscle mass were predictors of improvement in number steps mvpa. conclusion: this study suggests the need for pre-operative interventions by healthcare professionals that focus on outcomes such as improving low smm to facilitate post-operative pa recovery.. id="gencho_ronbuns10120898" class="qir_handle_link">
14. Yuriko Matsunaga, Kimie Fujita, Shuya Ide, Yasuko Tabuchi, Masaaki Mawatari, Kiyoko Makimoto, Changes in actual daily physical activity and patient-reported outcomes up to 2 years after total knee arthroplasty with arthritis, Geriatric Nursing, 10.1016/j.gerinurse.2020.07.006, 41, 6, 949-955, in press, 2020.11, The current study aimed 1) to describe changes in patient-reported outcomes and physical activity measured with an accelerometer preoperatively, 6 months and 2 years postoperatively in older patients undergoing total knee arthroplasty (TKA) for arthritis, and 2) to examine the predictors of the changes in physical activity (PA). This study included 58 patients (mean age 72.6 years, 84.5% women) who completed the Oxford Knee Score (OKS) and the 8-item Short Form Health Survey. Physical activity measured mean steps per day, duration of light physical activity and moderate-to-vigorous physical activity (MVPA) per week. All PA indicators and patient-reported outcomes improved 6 months postoperatively. After 6 months, knee-related pain and function gradually improved, and MVPA increased. The OKS was a sole predictor of improvement in PA during the 2-year study period, suggesting the importance of disease-specific quality of life..

Sayori Sakanashi, Kimie Fujita, Development of the empowerment scale for family caregivers of community-dwelling people with dementia in Japan, Japan Journal of Nursing Science, 10.1111/jjns.12311, 17, 2, 2020.04, Aim: This study aimed to develop the empowerment scale for family caregivers of community-dwelling people with dementia (PWD) in Japan (EFCD) and to validate the scale. Methods: The questionnaires were mailed to 820 family caregivers of PWD. The first version of the EFCD based on interviews with family caregivers and elderly care specialists and content validity results was tested. Participants also completed the Revised Scale for Caregiving Self-Efficacy and the General Health Questionnaire. For the EFCD development procedure, construct validity was evaluated by item analysis and exploratory factor analysis. Criterion validity was tested using Spearman's correlations between scores of the three scales. Reliability was evaluated using Cronbach's alpha, intraclass correlation coefficients (ICC), and Bland and Altman analysis. The final model was verified by confirmatory factor analysis. Results: Data from 304 family caregivers were analyzed. Exploratory factor analysis identified a 16-item, four-factor structure for the final version of the EFCD, as follows: (a) Excellent Practice in Dementia Care; (b) Understanding the Essence of Dementia Care; (c) Caring for Oneself as well as for the Person with Dementia; and (d) Having Peers with Shared Support Activities. Reliability and validity of the scale was established using the methods described. Conclusions: The developed EFCD is a reliable and valid measure that provides a simple assessment of empowerment among family caregivers of PWD..

17. Matsunaga-Myoji Y, Fujita K, Makimoto K, Tabuchi Y, Mawatari M, Three-Year Follow-Up Study of Physical Activity, Physical Function, and Health-Related Quality of Life After Total Hip Arthroplasty, The Journal of Arthroplasty, 10.1016/j.arth.2019.08.009, 35, 1, 198-203, Volume 35, Issue 1, January 2020, Pages 198-203, 2019.07, Background
Little is known about the long-term changes in physical activity (PA) after total hip arthroplasty (THA). The purpose of this study is to describe the changes in the number of steps and intensity of PA as measured by accelerometers, patient-reported physical function, and health-related quality of life of THA patient preoperatively and at 1 and 3 years after THA.
This study included 153 patients (mean age, 61.4 years; 86.3% women) who wore an accelerometer for 10 consecutive days and completed the Oxford Hip Score (OHS) and the Short Form 8 at the 5-year follow-up after THA. PA was evaluated based on the mean steps per day and the time spent performing moderate-to-vigorous PA (MVPA) per week.
All 5 indicators had significantly increased at 1 year after THA, although only MVPA and OHS had further increased significantly at the 3-year follow-up. The predictor of improvement in the number of steps from baseline to 1 year post-THA was younger age, while those of improvement in MVPA from baseline to 3-year post-THA were younger age, higher OHS, and better Short Form 8 mental component scores using mixed-model analysis. Participation in the PA measurements was high (69.9%) at the 3-year follow-up. No significant changes were observed for these outcomes in the remaining cohort beyond 3 years after THA.
In post-THA patients, MVPA continued to increase for 3 years postoperatively. Therefore, PA must be measured over the medium term to long term following THA..

Yuriko Matsunaga-Myoji, Kimie Fujita, Shuya Ide, Yasuko Tabuchi, Masaaki Mawatari, Improved levels of physical activity in patients over 75 years following total knee arthroplasty, Journal of Orthopaedic Surgery, 10.1177/2309499019873363, 27, 3, 2019.09, Purpose: There is insufficient evidence regarding the precise levels of physical activity (PA) in older patients following total knee arthroplasty (TKA). The aims of this study were (1) to describe the changes in the amount and intensity of PA before and after TKA with an accelerometer in older patients, compared with age- and sex-matched healthy participants and (2) to assess the effect of TKA on PA depending on age. Methods: Sixty-six primary TKA patients aged 60 years or over (mean age, 73.3 years) wore an accelerometer (Lifecorder EX) for 10 consecutive days and completed the Oxford Knee Score (OKS) before and at 6 months after TKA. PA was evaluated by mean step count and time spent (min) engaged in PA per day. PA intensity was classified as light (1.5–3 metabolic equivalents (METs)), moderate to vigorous (≥3 METs), and total (≥1.5 METs). Sixty-four healthy participants completed a single assessment of PA. Results: Each of the PA measures and OKS increased significantly after TKA. Compared with healthy controls, light and total PA improved to 100% at 6 months after TKA in patients 75 years or older. By contrast, moderate-to-vigorous PA was 32% of that of the controls and rose to 78% after TKA. PA intensity in patients aged 60–74 years was 31–74% of the controls but did not reach the same level after TKA. Conclusion: TKA in older patients increases the amount of PA, with light and total PA suitable parameters for assessing PA..

a retrospective analysis, Topics in Stroke Rehabilitation, 10.1080/10749357.2018.1507309, 25, 8, 591-598, 2018.11, Background: Physical activity (PA) is beneficial for stroke prevention; in particular, moderate-to-vigorous physical activity (MVPA). However, few studies have investigated its relationship with recurrent ischemic stroke (RIS). Objectives: To clarify the relationship between MVPA and RIS and the burden of risk factors after a first-ever ischemic stroke. Methods: A total of 45 outpatients (mean age 67.1 ± 10.2 years) who had previously experienced a transient ischemic attack or a minor non-cardioembolic ischemic stroke at a single hospital in Japan (mean 6.4 ± 4.2 years previously), were enrolled between March and June 2016. All patients wore an accelerometer around their hips for 10 days, and their percentage body fat (%BF) and visceral fat level (VFL) were measured by bioelectrical impedance. Retrospective information about the history of RIS and risk factors (blood pressure, lipoprotein cholesterol and estimated glomerular filtration rate) were extracted from the clinical records. Binary logistic regression models were used to estimate the relevance of the RIS history to MVPA and potential risk factors such as sociodemographic and clinical variables (obesity, smoking and hypertension). Results: RIS occurred in 9 patients; they had significantly higher VFL (p = 0.007) and %BF (p = 0.007) values and lower MVPA (p = 0.011) values than patients without recurrence. A multivariate analysis of these factors indicated that age, VFL and MVPA were significant independent predictors of RIS. Conclusions: Patients with a history of mild ischemic stroke had low MVPA and high VFL values, which together may be a risk factor for RIS..

21. Lin K, Bao L, Wang J, Fujita K, Makimoto K, Liao X., Validation of the Chinese (Mandarin) Version of the Oxford Knee Score in Patients with Knee Osteoarthritis, Clinical Orthopaedics and Related Research, 10.1007/s11999-017-5495-2, 475, 12, 2992-3004, 2017.12, Background: With the increasing number of patients with knee osteoarthritis undergoing TKAs in China, there is a clear need for a valid, short, joint-specific patient-reported outcome measure such as the Oxford Knee Score (OKS). Questions/purposes: To test the translated and cross-culturally adapted Chinese (Mandarin) version of the Oxford Knee Score (OKS-CV) and its (1) reliability, (2) construct validity, (3) dimensionality, and (4) responsiveness. Methods: Three native Chinese bilingual translators (a professional English translator, an experienced orthopaedic surgeon, an advanced-practice nursing specialist) translated the English-language OKS into Mandarin Chinese. A consensus panel created a synthesis of those efforts, which then was back-translated by two bilingual nonmedical, professional English-language translators. The OKS-CV was developed according to the guidelines of copyright holders. Between March 2013 and March 2015, 253 patients underwent TKAs. Among them, 114 Mandarin-speaking patients with knee osteoarthritis underwent primary unilateral TKA (age, 67 ± 7 years; range, 55–84 years; female, 80%; preoperatively 54% had moderate to severe knee osteoarthritis), completed the preoperative questionnaires, and were followed up, with a mean postoperative followup of 2.7 years (SD, 0.5 years). Eligibility criteria were (1) patients with knee osteoarthritis who were scheduled to have a primary unilateral TKA, (2) patients who were fluent in Mandarin, and (3) consent to participate. The exclusion criteria were: (1) lack of understanding of Mandarin, and (2) inability to comprehend the questionnaires owing to cognitive impairment. To evaluate test-retest reliability, another group of 35 Mandarin-speaking outpatients with knee osteoarthritis (age, 61 ± 10 years; range, 44–84 years; female, 77%) was recruited to complete the OKS-CV twice at a 1-week interval. Reliability was tested using Cronbach’s alpha and intraclass correlation coefficient (ICC). Construct validity was evaluated using Spearman’s rank correlation coefficient to quantify the correlations between the OKS-CV and the WOMAC, Short Form-8 Health Survey (SF-8TM), and EuroQol Group 5-Dimension Self-Report Questionnaire (EQ-5D). Exploratory factor analysis was performed to clarify dimensionality. The eigenvalue indicates the importance of each factor obtained from factor analysis. Responsiveness was determined by standardized response mean (SRM) and effect size (ES) from preoperative and postoperative scores of the OKS-CV. Floor and ceiling effects also were analyzed. Results: The internal consistency (Cronbach’s alpha = 0.89) and test-retest reliability (ICC = 0.93; 95% CI, 0.87–0.97) proved good. Convergent construct validity was supported by moderate to strong correlations between the OKS-CV and the WOMAC (r = −0.80, p TM physical component summary (r = 0.65, p TM mental component summary (r = 0.58, p

A concept analysis, International Journal of Nursing Practice, 10.1111/ijn.12573, 23, 5, 2017.10, Aim: This concept analysis defined and described the components of empowerment of family caregivers who care for adults and the elderly. Methods: Rodgers evolutionary method of concept analysis was used. Data sources included Pub Med, CINAHL, Scopus, and Igaku Chuo Zasshi. Thirty articles published between 1995 and 2015 focusing on the empowerment of family caregivers providing care to adults and the elderly were selected. Result: The analysis reveals 6 attributes, 5 antecedents, and 5 consequences. In addition, the results reveal structured aspects of family caregivers, care receivers, and other people surrounding them, and their relationships. Empowerment of adults' and elders' family caregivers may be defined as “positive control of one's mind and body, cultivating a positive attitude, proactively attempting to understand one's role as a caregiver to improve caregiving capabilities, focusing on others as well as oneself, supporting the independence of the care receiver, and creating constructive relationships with other people surrounding them.”. Conclusion: The components of empowerment clarified in this research can be used for the measurement of and interventions aimed at improving empowerment among family caregivers. Furthermore, clarifying the definition of empowerment among family caregivers enables researchers to better distinguish empowerment from similar concepts in the future..

Fujita K, Makimoto K, Mawatari M., Three-year follow-up study of health related QOL and lifestyle indicators for Japanese patients after total hip arthroplasty., J Orthop Sci., 10.1016/j.jos.2015.11.004., 21, 2, 191-198, 2016.04, BACKGROUND:In non-Western countries including Japan, activities requiring deep flexion of the hip joint, such as seiza (kneeling with calves tucked under the thighs and buttocks resting on the heels) and using squat toilets are commonly practiced. The purpose of this study was to assess longitudinal changes in traditional health-related quality of life measures and measures of physical functions associated with lifestyle for Japanese patients pre-surgery and after total hip arthroplasty.
METHODS:Consecutive primary total hip arthroplasty patients between July 2003 and November 2006 were eligible. Patients were measured preoperatively and at 6 weeks, 1 year and 3 years postoperatively. Patients completed the EuroQol 5D, the Western Ontario and McMaster Universities Osteoarthritis Index and items related to Japanese lifestyle activities such as squatting. Changes in these scale scores across the four time points were tested, and we examined predictive factors of EuroQol 5D score at 3-year follow-up using multiple linear regression.
RESULTS:Of 1103 eligible patients, 576 completed questionnaires at all four time points. By 6 weeks post-surgery, reductions in pain and improvements in physical function and stiffness became highly significant, and improvements continued to 3 years postoperative. In contrast, improvements were far more limited for items related to Japanese lifestyle functions such as seiza and use of a Japanese squat toilet, even 3 years after surgery. Predictive factors of EQ5D at 3-year post THA were WOMAC pain and physical function, seiza, age and comorbidity measured at 3-year post THA.


The rate of improvement in QOL requiring deep flexion of the hip joint was much slower than that in QOL related to Western lifestyle. Our study suggests a need for lifestyle modification for THA patients in the other countries where kneeling and squatting are commonly performed..

Myoji Y,Fujita K,Mawatari M,Tabuchi Y., Changes in sleep-wake rhythms, subjective sleep quality and pain among patients undergoing total hip arthroplasty, International Journal of Nursing Practice, 10.1111/ijn.12345, 21, 6, 764-770, 2015.12, We evaluated nocturnal sleep-wake rhythms and subjective sleep quality on the first postoperative night compared with the preoperative night in 34 patients who had total hip arthroplasty (mean age: 61.9 years; 82.4% female) under spinal anaesthesia. We also examined secondary factors related to sleep disturbances after surgery. Patients wore an accelerometer (actigraph) during the preoperative period and the first postoperative night to track sleep-wake rhythms. Secondary end-points were postsurgical pain and low back pain. Sleep parameters were measured objectively by actigraphy, and subjective sleep quality was measured by the Oguri-Shirakawa-Azumi Sleep Inventory, Middle-Aged and Aged Version and found to worsen significantly after surgery. Actigram data showed a reduction in actual sleep time from 353.7±121.2min preoperatively to 263.8±104.4min postoperatively. The data indicate that normalized continuous sleep time is important for patient healing and well-being and that postoperative sleep disturbance is related to low back pain more than to postsurgical pain..
