ABSTRACT
<b>Objective</b> : The purpose of this study was to examine the relationships between levels of self-efficacy on health behavior of outpatients with rheumatoid arthritis (RA) and patient's assessment of RA conditions.<br><b>Methods</b> : A cross-sectional study was performed using a self-administered anonymous questionnaire between October and December 2010 on 406 RA outpatients who consecutively visited 3 urban hospitals in Japan. The following variables were investigated ; (1) the scale of self-efficacy on health behavior in chronic disease patients (CD-SES), which has 2 subscales : active coping behavior with disease (14 items) and controllability for health (10 items). (2) The demographic data ; age, gender, duration of disease, treatment. (3) patient's assessment of RA conditions : painful joint count, swollen joint count, serum C reactive protein (CRP), patient estimate of global status (PGS) which was measured on a 100-mm visual analogue scale (0=best score), functional disability according to Japanese version of modified Health Assessment Questionnaire.<br><b>Results</b> : CD-SES data were obtained from 191 patients. 80<b>%</b> was female with mean age 64.4 yr. Total CD-SES scores significantly correlated with age, PGS and functional disability. The scores of active coping behavior with disease correlated with age, and the scores of controllability for health correlated with PGS. The other variables such as painful joint counts, swollen joint counts, and serum CRP showed no relationship with the scores of self-efficacy.<br><b>Conclusion</b> : Self-efficacy on health behavior of RA patients related to PGS and functional disability. The longitudinal study is necessary to ascertain whether the psychological support enhances self-efficacy, and affects clinically important outcome measures such as PGS.
ABSTRACT
<b>Purpose:</b> The Schedule for the Evaluation of Individual Quality of Life - Direct Weighting (SEIQoL-DW) is designed to investigate an individual's perspective on their own quality of life (QOL) and has been used widely among various clinical populations, including cancer patients and those with chronic kidney disease, in addition to healthy participants. While the original SEIQoL-DW is a semi-structured interview, other formats have been developed; recently computer-based versions have yielded equivalent results comparable to paper-based versions. However, no previous study has examined differences between the computer-based version and its original interview-based design. The purpose of this study is to assess the feasibility and validity of a computer-based version of the SEIQoL-DW, compared with the original interview-based format.<br><b>Methods:</b> We conducted a non-randomized crossover study with 13 medical students from November 2008 to January 2009 at a municipal university in Yokohama, Japan. Both the computer-based and interview-based versions of SEIQoL-DW were administered to all study participants. Wilcoxon-signed rank test was used to compare differences in mean SEIQoL Index score between computer-based and interview-based results. The intra-class correlation coefficient and the Bland and Altman limits of agreement methods were used to compare formats.<br><b>Results:</b> No significant differences were found in the SEIQoL-DW Index between the computer-based and interview versions after analysis with Wilcoxon-signed rank test (p = 0.501). The intra-class correlation between formats was 0.94 (CI: 0.81–0.98). The limit of agreement analysis showed that 53.3% of the observations were within ±1–5 units of the average score, while 46.7% were within ±5–10 units. In total, 100% of observations were within ±1–10 units.<br><b>Conclusions:</b> The computer-administered version of SEIQoL-DW may be feasible and acceptable and provides a valid alternative, at least in healthy subjects, to the more cumbersome interview version. Use of the computer-based version will facilitate its application to larger patient populations in various clinical settings.
ABSTRACT
<b>OBJECTIVE</b> : This study was conducted in a Japanese population to better understand the association between insomnia and sleeping prone.<br><b>METHODS</b> : A cross sectional questionnaire study was conducted with outpatients of St. Luke's International Hospital in August, 2007. Information on sleep position habits, symptoms, quality of life, and sleep quality was collected. The Athens Insomnia Scale (AIS) was used to measure sleep quality. Participants with an AIS score of 4 or higher were categorized as sub-threshold insomnia and as the insomnia group.<br><b>RESULTS</b> : Of the 784 subjects who returned completed questionnaires (response rate=65%) 30.4% were men. About 13% of the respondents slept in the prone position at least three times a week. Based on multivariate adjusted logistic regression analysis, there was a significant association between sleeping prone and having no problem with insomnia (odds ratio, 0.61 ; 95% CI, 0.38-0.99).<br><b>CONCLUSION</b> : These data suggest that sleeping in the prone position is associated with good quality sleep.
ABSTRACT
BACKGROUND: Use of complementary and alternative medicine (CAM) has become popular in Japan.<BR>OBJECTIVE: To investigate associations of symptom-related CAM use with sociodemographic factors in Japan.<BR>DESIGN AND SETTING: A prospective cohort study of a nationally representative sample of households in Japan.<BR>PARTICIPANTS: Community-dwelling adults who developed at least one symptom during a 31-day period.<BR>MAIN OUTCOME MEASURES: Self-reported, symptom-related use of CAM, either physical CAM or oral CAM.<BR>RESULTS: Of 2, 453 adults, 2, 103 participants (86%) developed at least one symptom. Of these symptomatic adults, 156 (7.4% ; 95% CI: 6.3-8.5%) used physical CAM therapy. The likelihood of using physical CAM was not significantly influenced by annual household income, employment, or education. Participants living in large cities had an increased likelihood of using physical CAM with an odds ratio (OR) of 2.6 (95% CI: 1.2-5.8), compared to those living in rural areas. Oral CAM therapy was used by 480 participants (22.8%; 95% CI: 21.0-24.6%) among the symptomatic adults. An age of 60 years old and older (OR 2.0; 95% CI: 1.2-3.3) and female gender (OR 1.8; 95% CI: 1.3-2.6) were significantly associated with an increased use of oral CAM. The unemployed participants had a lower likelihood of using oral CAM, with an OR of 0.6 (95% CI: 0.4-0.9), compared to the employed.<BR>CONCLUSIONS: Oral CAM use is common among Japanese patients and is associated with older age, female gender, and employed status, while physical CAM use is less common and is associated with living in a large city.
ABSTRACT
OBJECTIVE: To investigate Japanese physicians' use of dialects related to geographic areas and to elucidate how physicians respond to dialect-using patients.<BR>METHODS: We conducted a web-based open survey, to which 170 anonymous physicians reported. We examined the following 1) whether dialects are used during communication with patients; 2) how to communicate with patients using dialects; and, 3) reasons for having difficulty in communicating with patients who regularly use dialects. Geographical areas were divided into the following 8 areas Hokkaido-Tohoku, Kanto, Koshinetsu-Hokuriku, Tokai, Kinki, Chugoku, Shikoku and Kyushu-Okinawa.<BR>RESULTS: Of 170 physicians, 61.2% (95% CI: 53.4-68.5%) reported using dialects. These proportions differed by geographic area (F= 8.141; p<0.001) . Physicians practicing in Shikoku and Chugoku used dialects most frequently, while those practicing in Kanto and Hokkaido-Tohoku used dialects least frequently. Many dialect-using physicians thought that physicians should use the same dialect as dialect-using patients. In addition, dialect-using physicians were more likely to think that a physician-related factor was responsible for having difficulty in garnering clinical information.<BR>CONCLUSIONS: Use of dialects by Japanese physicians during communication with patients seems common and may differ by geographic areas. Physicians' use of dialects could be a useful tool for effective clinical communication.
ABSTRACT
<b>BACKGROUND</b> : Previous studies have suggested positive association between residents' workload and medical errors. However, few studies have investigated the possible associations between procedural errors, workload, and the individual characteristics of residents, including personality, mental state and job satisfaction.<br><b>OBJECTIVE</b> : To explore possible associations of workload and individual characteristics of residents with their procedural error rates.<br><b>DESIGN</b> : Prospective observational study based on a daily questionnaire.<br><b>PARTICIPANTS</b> : Residents of postgraduate year 1 and 2.<br><b>MEASUREMENTS</b> : Residents' workload (on-calls, work hours, sleep and napping hours), residents' physical and mental health state, personality inventory, and procedural error rate (defined as procedural error counts divided by overall procedural attempts).<br><b>RESULTS</b> : On average, the residents (N=49) were responsible for 9.8 inpatients per day (range, 1.9-23.1), worked for 16.0 hours per day (range, 12.6-19.8), slept for 4.4 hours per day (range, 2.8-5.7), napped for 0.2 hours per day (range, 0-0.7), and experienced 1 overnight work shift every 7.2 days. The procedural error rate was 2.2 per 10 procedures (range, 0.4-5.0). Using a multivariable adjusted regression model, significant factors associated with lower error rates included : longer napping ; reflective personality ; better mental state ; higher job satisfaction ; and, less on-call frequency.<br><b>CONCLUSIONS</b> : Procedural error of residents is positively associated with higher on-call frequency and inversely associated with napping, reflective personality, better mental state, and higher job satisfaction. For reducing procedural error among residents, improvement of modifiable factors, such as workload and mental health, is needed.
ABSTRACT
In 2006 26 first-year residents at St.Luke's International Hospital underwent training with a highly sophisticated simulator to learn how to treat patients with cardiopulmonary arrest or anaphylactic shock.We evaluated the effects of simulation training for first-year residents.<BR>1) After training, we analyzed the residents' performance in the 2 scenarios and the residents' satisfaction with simulation training.<BR>2) According to the resident's performance dataduring simulation training, first-year residents have sufficient skill to treat patients in cardiopulmonary arrest but not patients with anaphylactic shock.<BR>3) Twenty-five of the 26 residents (96.2%) were highly satisfied with simulation training.
