This case report aimed to compare the outcomes of these two methods and provide a good indication of the method that should be selected in case of a pandemic.Methods　For on-site inspections, documents, including checklists, were sent to 351 hospitals from the Osaka City Public Health Office, and responses from each hospital were returned. On-site inspections were conducted, and the written instructions that indicated inadequate aspects and guidance were mailed to hospitals.For document-based inspections, documents were sent to 176 hospitals, and responses were returned. For hospitals that answered \"incomplete\" regarding the categories of medical safety management systems and hospital-acquired infection control, public health physicians called to confirm and instruct their inadequate responses, and the same step as the on-site inspection was executed. We compared and examined the outcomes of the on-site and document-based inspections.Results　In the on-site inspections, 12 of the 351 hospitals (3.4%) were recognized as inadequate because of a shortage of healthcare workers. In the document-based inspections, eight out of 176 hospitals (4.5%) were identified, and there was no significant difference.Regarding the medical safety management system, 95 of the 351 hospitals (27.1%) on on-site inspection and 21 of the 176 hospitals (11.9%) on document-based inspection received written instructions. The proportion of hospitals that received written instructions was significantly higher for on-site inspections than for document-based inspections (P < 0.001).For hospital-acquired infection control, 65 of 351 hospitals (18.6%) on on-site inspection and 17 of 176 hospitals (9.7%) on document-based inspection got written instructions. The proportion of hospitals that received written instructions was significantly higher for on-site inspections than document-based inspections (P = 0.007).Conclusion　Document-based inspection can easily unify the guiding criteria with fewer public health physicians. However, because of the limited amount of information available without checking the documents retained in hospitals, it is difficult to monitor the matters that need instructions. Thus, on-site inspection is preferable. However, if onsite inspection is difficult, inspection combined with online methods should be considered.</p>","PeriodicalId":72032,"journal":{"name":"[Nihon koshu eisei zasshi] Japanese journal of public health","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142633130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study focused on the terms \"individual evacuation plan,\" \"residents requiring assistance in evacuation,\" and \"welfare shelters\" among physiotherapists, and the degree of knowledge and factors associated with knowledge of these terms were examined to consider ways for physiotherapists to participate more actively in disaster response.Methods　A web-based survey was conducted among members of the Fukushima Physical Therapy Association from March 8-31, 2023. The survey items included basic attributes, knowledge of \"individual evacuation plan,\" \"residents requiring assistance in evacuation,\" and \"welfare shelters,\" and the presence of opportunities to acquire knowledge, own evacuation experience, and experience supporting disaster survivors. The association between knowledge and length of career as a physiotherapist, presence of opportunities to acquire knowledge, own evacuation experience, and experience supporting disaster survivors were examined using the χ² test and residual analysis. Additionally, respondents were asked regarding their understanding of the physiotherapy recipients' \"individual evacuation plan\" and participation in formulating those plans. Those who understood and participated in those plans were asked to provide a free-form response about the use of the \"individual evacuation plan\" in providing routine physiotherapy and specific activities.Results　Of the 1,645 participants, 171 (10.4%) responded.

This study aimed to estimate long-term trends in the intensity of occupational PA, constituting the largest portion of PA in Japan.Methods　Data on the number of workers in Japan by occupational category were obtained from the Labour Force Survey. PA intensity (metabolic equivalents [METs]) was assigned to 329 occupations in the Japanese Standard Occupational Classification based on the methods and data of Tudor-Locke et al. (2011), and representative intensity values for 11 occupational categories were calculated. Based on intensity, occupational categories were reclassified into sedentary (≤1.5 METs), light (1.6-2.9 METs), and moderate (≥3 METs). Trends in the prevalence of workers in each category were analyzed, along with the annual mean occupation-related METs from 1953 to 2022. The mean occupation-related METs represented the weighted average of PA intensity, calculated based on the annual worker population for each occupational category. Results　From 1953-2022, the prevalence of moderate-intensity occupations significantly declined, whereas sedentary and light-intensity occupations increased. The mean occupation-related METs decreased continuously for 70 years. During the 48-year period from 1962 to 2010, when there were no major changes in occupational classification methods, there was a decline of 0.25 METs, representing a 9.6% decrease, from 2.60 to 2.35 METs.Conclusion　Over the past 70 years, occupations in Japan have transitioned to ones with lower PA intensity. Consequently, the average PA intensity across all occupations decreased by at least one-tenth.

The survey content included teachers' knowledge of gaming disorders, whether their students experienced gaming-related problems, difficulties perceived by teachers, how they discovered the problems, how they dealt with them, the challenges they faced in dealing with the problems, and desired support. Data were analyzed based on the teachers' roles, responsibilities, type of school, and knowledge of gaming difficulties. Fisher's exact probability tests were used to determine significance, and adjusted standardized residuals were used to assess the differences between groups.Results　Nearly 63.1% of the teachers already had knowledge of gaming disorders, and 49.4% acknowledged the existence of students with gaming problems. The most common reasons for discovering problems were disrupted daily rhythm (51.7%) and increased tardiness and early dismissal (34.7%). The main actions taken to address gaming problems were \"consultation and information sharing with families\" (48.6%) and \"individual guidance by teachers\" (34.1%). Approximately half of the teachers indicated that they regularly experienced difficulties in activities related to prevention, early detection, student support, and interaction with parents. Specific challenges included limited guidance and involvement with families (61.4%) and the inability to intervene and provide effective support (62.5%). Teachers' support included programs for addiction recovery (56.8%), awareness programs for parents (56.0%), and staff training to increase the understanding of gaming disorders (50.5%).

We identified four key factors to pinpoint the challenges and enhance opportunities for introducing GSM; GSM's operational achievements, a comparison of the characteristics of GSM users and non-users, purpose for using GSM, and observation of GSM's contribution to long-term care prevention among older adults.Methods　A pilot GSM study was conducted in Ikeda City, Osaka Prefecture, from October to December 2022. The service included three routes, operating six times daily on a fixed schedule, and was provided by 10 volunteer drivers. Passengers signaled for boarding, and service details were provided through leaflets. A self-administered mail survey was conducted before and after the demonstration test with 674 respondents to the post-questionnaire, and 502 respondents were asked at both time points about issues related to the service, user characteristics, and care prevention. To assess care prevention, we examined the percentage of favorable changes triggered by GSM based on \"opportunities to go out,\" \"personal and behavioral aspects,\" \"social relations,\" and \"psychological aspects.\" Additionally, we examined whether the health indices in the post-hoc survey were better among GSM users than non-users.Results　Of the 223 scheduled GSM services, 214 (96.0%) were operated by 10 volunteers driving an average of 3.1 (SD 2.4) times weekly (0-11 times), indicating an uneven distribution of driving responsibilities. Among the users, 65 (9.6%) were more engaged in community activities and emotional support than non-users. The main purposes for using GSM services were shopping and medical visits, with approximately 70% of users finding it easier to go out owing to these services. The percentage of favorable changes were noted in 3.1-26.2% and 0.2-1.5% of users and non-users, respectively. In the post-test survey, users showed higher independence on the instrumental self-maintenance subscale than non-users.Conclusion　GSM facilitates outings among older adults and may reduce the need for potential long-term care.

Developing resilience at a young age promotes mental health and provides benefits throughout one's lifespan. Validated measures for assessing resilience at a young age are required in both clinical practice and epidemiological studies. The Child and Youth Resilience Measure-Revised (CYRM-R) is a tool used worldwide to assess resilience in children and young people. The objective of this study was to develop a Japanese version of the CYRM-R and investigate its psychometric properties.Methods　Children in grades 5-9 were recruited via a two-stage cluster random sampling taken from the Japan Adolescent and Youth (JAY) Longitudinal Cohort Study. The participants completed the Japanese version of the CYRM-R . The CYRM-R consists of two subscales, personal resilience and caregiver resilience, with a total of 17 items. The linguistic validity of the Japanese version of the CYRM-R was ensured through translation and back-translation.Cronbach's alpha coefficients were examined for the total score and the two subscales to assess the internal consistency of the Japanese version of the CYRM-R scale. In addition, correlation coefficients of the subscales were calculated. For factorial validity, a confirmatory factor analysis was conducted on the same two-factor structure as in the original version to assess the model's goodness of fit. Results　A total of 2,266 children (50.0% male) were included in the study. The overall Cronbach's alpha of the Japanese version of the CYRM-R obtained from this sample was 0.956; For the personal resilience subscale, Cronbach's alpha was 0.932; for the caregiver resilience subscale, it was 0.919.

Consequently, the Better Life Index (BLI) developed by the Organisation for Economic Co-operation and Development (OECD) has emerged as a pivotal multidimensional measure of well-being, surpassing traditional indicators such as Gross Domestic Product (GDP). However, current well-being indicators predominantly focus on national measurements and do not effectively evaluate well-being in smaller regions such as states or prefectures. This study aimed to calculate a Regional Well-Being Index (RWI) tailored to localized areas in Japan.Methods　Japanese official statistics, publicly available as open data, were analyzed, focusing on 11 domains similar to those in the BLI: \"Income,\" \"Jobs,\" \"Housing,\" \"Health,\" \"Work-Life Balance,\" \"Education,\" \"Community,\" \"Civic Engagement,\" \"Environment,\" \"Safety,\" and \"Life Satisfaction.\" The RWI scores were calculated for each prefecture in 2010, 2013, 2016, and 2019 using standard normalization techniques. To represent the overall well-being of each prefecture in each year, scores were aggregated across all domains; this aggregate is referred to as the Integrated RWI. The reliability and validity of RWI were assessed by examining time-series changes and Pearson's correlation coefficients.Results　Median Integrated RWI scores for Japanese prefectures remained relatively stable across the study period, with slight variations observed: median = 0.67 (Interquartile range [IQR]: -2.48-2.71) in 2010, median = 0.00 (IQR: -2.85-2.76) in 2013, median = 0.13 (IQR: -3.05-2.49) in 2016, and median = 0.19 (IQR: -2.75-3.06) in 2019. Geographical analysis showed lower scores in regions such as Western Kyushu and Shikoku, and higher scores in Chubu and Eastern Kinki. The RWI and the BLI demonstrated construct validity, with Pearson's correlation coefficients ranging from 0.58 to 0.99 across various domains.Conclusion　The RWI, based on the OECD's BLI, proved to be a reliable and valid tool for assessing comprehensive well-being at the regional level in Japan.

In Japan, although each municipality performing cancer screening programs implements quality control for their programs using the checklist authorized by the Ministry of Health, Labour and Welfare, compliance with all the items listed is not possible because calculating sensitivity and specificity using cancer registry data is difficult under these circumstances. This report elucidates the methodology for calculating indicators, including sensitivity and specificity, by delineating the parameters of false-negative cases within population-based cancer screening programs in Japan. Furthermore, the inherent challenges associated with ensuring the quality control of cancer screening procedures are expounded upon in this report.Method　Data from the Prefectural Cancer Registry of Japan and cancer screening records compiled by municipalities were used to differentiate true-positive, true-negative, false-positive, and false-negative cases based on the combination of screening test outcomes and subsequent cancer incidence.Results　A false-negative case was defined as an examinee who received a cancer diagnosis within one year after undergoing the screening test, notwithstanding the negative judgment of the cancer screening decision. The duration for judgment of true-positive, true-negative, and false-negative cases was also extended to one year. Cancer identification after cancer screening was ascertained using data from the Prefectural Cancer Registry, ensuring uniform categorization of the four cases. Subsequently, sensitivity and specificity values were calculated for municipalities conducting cancer screening programs.Conclusion　Sensitivity and specificity are indispensable metrics for the inherent quality control of cancer screening because these parameters directly assess the efficacy of screening tests. The anticipated increase in the number of municipalities engaged in comprehensive quality control of cancer screening in Japan is poised to enhance the efficiency of cancer control policies.
